Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.
This seemed like a solvable problem.
Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.
Here's how it works: Find a product (or suggest one), contribute to its testing fund, get detailed lab results when testing completes. If a product doesn't reach its funding goal within 365 days, automatic refund. All results are published openly. Laboratory.love uses the same methodology as PlasticList.org, which found plastic chemicals in everything from prenatal vitamins to ice cream. But instead of researchers choosing what to test, you do.
The bigger picture: Companies respond to market pressure. Transparency creates that pressure. When consumers have data, supply chains get cleaner.
Technical details: Laboratory.love works with ISO 17025-accredited labs, test three samples from different production lots, detect chemicals down to parts per billion. The testing protocol is public.
So far a couple dozen products have received some funding, six products have been fully funded (five product results published, the sixth is at the lab as I write this!)
You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love
Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.
I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.
This is great. I thought about a different model even before plasticlist: make a subscription and test various products, but people will have a number of upvotes based on their sub streak. They vote for food to test, and then you show results to everyone subbed. Kind of like what examined does, but they do deep dives into medical topics for subs. I think this model will work better than the one you currently have. Awesome project anyways!
It is extremely weird to me that countries don't do that on taxpayers money and show the results publicly, this is what they should do.
I definitely considered a voting mechanism, but there are a few million active, buyable CPG UPCs in the U.S. at any given time. When conducting some basic market research for this project, I found that most people are only willing to pay to find results about the specific products they care about.
What would be a good strategy to prevent companies from cottoning on to this and gaming the system? They could for example change packaging on production runs for a product that’s undergoing laboratory.love funding campaign.
It's an interesting thought. Companies do change packaging somewhat regularly. However, the underlying skew usually remains the same. Changing the packaging and/or the SKU is very expensive. It's probably cheaper and more beneficial to your company to do your own Plastic Chemical testing and get ahead of the problem.
My suspicion is if this was gameable, this would be a solved problem by a number of companies. The truth is there is no single simple or even hard step to take, it’s mostly like numerous steps that multiple actors would need to do.

The product label images loading on the homepage are huge right now. They are displayed in 128px * 128px box but are about 2 MB in size each. May be generate resized versions at build time and use <picture> tags?
This is so incredibly important, well done. The problem of our food being steeped in plastic hits the news here and there, but it should be front and center in my opinion. Testosterone has been plummeting for decades and it scares the heck out of me. The hormone whose job is "form goals, shrug off failure, and try again!" is being destroyed and corporations are given a free pass to pump us full of phthalates and bisphenol. It's infuriating.
And anecdotally, I've still been forming goals and shrugging off failure five years into suppressing most of my endogenous testosterone with exogenous estrogen
Well that's great for you, but I was making a generalized statement about the role of testosterone, scientific data showing huge decline, and more and more studies linking it to plastics. We can't just alter a key hormone within the span of a few decades and shrug it off. My levels are great for a 40 year old
And yes there are certainly other factors, but that's not what the original comment was talking about?
I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet).
It uses 4k stereoscopic capture and bunch of ML models to match bone position with sub-millimeter precision. The surgeon screws a metal base piece into the bone, and we detect where that is in space. Then, a Stewart Platform adjusts another part that is placed onto the base. The robotic adjustment allows the base to be placed in a ballpark area, with the robotically-adjusted piece oriented in the exact spot where the surgeon needs to cut.
The net result is a robotic system that is many times cheaper than the least expensive incumbent, decreases surgery time significantly, reduces error, and basically "just works" as opposed to requiring a ton of training. We are debuting at a tradeshow in October.
This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing
I'm working on Small Transfers (https://smalltransfers.com/), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers.
You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets.
If combined with subscriptions, the pricing can work similarly to mobile plans, where monthly plans become cheaper above a certain usage threshold.
Looking for more developers to try it and share feedback.
Replicated Data exchange format, RDX. A JSON superset that has diff, patches, branches and merges. Once you have that ability at the data format level, many things become surprisingly straightforward.
https://github.com/gritzko/go-rdx
This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .
It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.
Nice project! The National Library of Scotland has a nifty tool focused mainly on the UK and Ireland that does something similar (with a paid print service attached):
https://maps.nls.uk/geo/find/marker/
I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps.
That's nice! I have some GIS data of my country it was pretty detailed, it may be outdated now, but covered a good amount of administrative details. If you are extending and need some data on Bangladesh, I can send you
Have you looked into speaking with the various SHPOs in each US State/Territory?
I've worked with several of them a fair bit and they have a ton of old maps hidden internally. Especially for small, specific areas of the state, like historical districts.
Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.
I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups.
Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those services provided all the information on a book. One might provide the series, the other might provide genres, and yet another might provide a cover with good dimensions, but none provided everything, so I decided to work on something of my own (called Librario).
While Shelvica is the focus, Librario could become its own thing in time, so I don’t mind the sidetracking.
I also plan on having a “ISBN Search” kind of website that feeds from that database as a way to let users search for information about books, which then feeds the service’s database, making it stronger for Shelvica.
I open source everything I make, but I’m still wondering if these will be open sourced or not. I’ll probably go with the EUPL 1.2 license if I do decide on open sourcing them.
[1]: My wife and I have a personal library with around 1800 books, but most applications for management are either focused on ebooks or choke with this many books. Libib is the exception, but I wanted a little more.
Didn’t have the time yet, but it’s on my todo list. I have extractors for Google Books, Hardcover.app, and ISBNDB already working, and Amazon, Goodreads, and Anna’s Archive in the todo list.
I do plan on including a link to the book on Anna’s Archive in the “ISBN Search” website. At least to the search page with the filters already filled.
Hey I'd like to learn more about what you're doing. I'm working on a tangentially related service but focusing on audiobooks. One big stumbling block I ran into early on was trying to find something close to a unified ISBN datasource.
If you're up for it, shoot me an email at charles@geuis.com.
I attempted something like this because I wanted a good books search service which provided me at-a-glance information I needed from Storygraph & Goodreads. The main things I look for when I search a book is genres/Storygraph's "moods", number of pages, whether it's part of a series, rating across services & how much does it cost.
I'm super curious if anybody will pick it up and do something useful with it. This was a couple of years of my life and I absolutely loved working on it but having a child put a hard stop to such entertainment for many years. Now, a good 30 years later I finally found the time to resurrect it.
I'm not sure yet if I am going to do more work on it or leave it as it is, it's good enough to give someone new to OS development a running start and a foundation to build on.
In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.
Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).
Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!
That's such a great idea. Especially since you're also helping the restaurants out. Nowhere near that area otherwise I would've petitioned straight away
The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circuitscript tool (currently only the desktop cli tool) is able to generate KiCAD netlists and this can be imported into PCBnew.
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
As a big openscad fan I love the idea of designing circuits with code.
I do wonder though about designing circuits vs designing schematics. I see you have ‘wire down 100’ making it a more visual language than defining the nets. Be interesting to separate the schematic layout from the nets, so rule base schematic layout can then be applied.
I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy.
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a small forest).
Great to see something along those lines but with much better visuals.
Working on a dutch voting compass that uses real world motion votings as a way to determine which party fits you best. The Netherlands got an open API for this since last year, so it felt appropriate to start using it.
It prioritizes accessibility, longevity, performance, and simplicity.
With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)
Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.
All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).
Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.
Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator
The library is free for personal, educational, non-profit use. Commercial use requires a license.
Impressive! Feels really responsive. I feel the controls are a little unusual though: WASD corresponds to actual map orientation rather than to where the character is facing. I find it confusing when playing together with a mouse, where I would expect I can hold W to move forward while using the mouse to control the character's orientation and direction.
The initial implementation actually used that approach - but I got some complaints from people saying it felt weird and I changed it. That was a long time ago during prototyping though - might change it back and see how it feels now (or just add an option). Thanks for the feedback.
I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).
My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.
Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.
The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.
I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.
My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.
Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk
I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.

A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use.
There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.
I'm currently building Visirya, an app that helps people record their night dreams and transforms them into short videos and written journals. The bigger goal is to use this dream data to create dream cartographies, essentially maps of recurring themes, emotions, and symbols—to uncover patterns and insights across dreams over time.
So far, we've built the video generation and dream journaling features. The app is live on TestFlight, and we're preparing a major update soon that includes a new better UI, and dream questionnaire to help with pattern recognition and dream mapping.
Would love to hear thoughts, feedback, or connect with others working on similar intersections of tech and the mind! If you're interested in trying it out, you can find the TestFlight link on our website: https://visirya.com
The idea is nice, but I wonder if a generated video can have any resemblance of the actual dream. At least for me, dreams are very tied to emotion, and the visuals are kinda blurry, so i don’t know if that sort of thing can provide any satisfaction. But I know certain aesthetics can feel “dreamlike”.
Super cool! I'm building in the same space but for Muslims - Dreamstate: Interpret your dreams Islamically https://dreamstateai.replit.app/
I tried your app - it's quite abrupt to go straight to Access Microphone permissions. The voice recording took a long time to analyse, it timed out for me. It's a great idea but didn't work for me unfortunately.
On the side, custom coloring books for kids using nano banana, started with a project for my son, and its a little janky for some photos but have had some interest already: https://bespokebooks.io. I think it needs to be a phone app to really work for most people though, so that's next on my to do list besides some prompt tweaking.
I think there are a lot of really fun projects possible now in the child book creation space, particularly as you build tools that they can use themselves (like adding voice interfaces to building a book or story).
This is outside my 996 job of AI Agent/Assistant infra + ops :)
Working on a webapp for critically think with others about a problem.
The idea is that you build a diagram that contains all the details about the problem and people's thoughts on it, and it's organized in such a way that it's easy to just keep refining, down to the smallest detail. So you build this concrete, shared understanding, and move it forward and forward, until hopefully y'all can make some best decision to improve the situation.
There's a lot to do. Currently working on UX to allow hiding intermediate nodes and still have indirect edges drawn. Want to add an LLM integration to generate/update diagrams via natural language, which I think will help a lot with usage barriers to using the app.
I wanted something similar for a worldview. I want an app where I can dump all the things that actively go into shaping my worldview and then when someone wants to know why I think the way I do, I will share them the link of my worldview board. We are not famous people to have our memoir written but this is another way to peek into minds of strangers.
That's a cool idea. Seems like there would be a ton of things contained in an individual's worldview, that it'd be hard to build all of it up. Perhaps when you encounter something that makes you think of some core philosophy, you note it and the philosophy, and eventually there would be a loose picture that forms amongst all the relations.
Certainly would be helpful for trying to understand someone else. Not sure if this is totally appropriate, but it does seem like something that a chatbot would be good at combing through to find examples to suggest why one thinks a certain way about a new topic. You could even ask it about your own worldview!
Postply uses full-context to generate better replies on X, Instagram, Facebook & LinkedIn.
It supports custom reply profiles and styles for support teams and social media managers.
There are clearly a lot of AI replies on social media already, but they are really generic and bad.
With Postply.com I'm hoping it will help people generate better and more meaningful replies.
Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.
I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.
The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.
I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.
Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.
Great instructional video. First place I learned E natural minor with his scale fragments section.
Yes, not a new technique by any stretch of the means. AFAIK John Petrucci takes a less aggressive approach with raising BPM. Funnily, Shawn Lane goes into a very similar methodology >30 years ago[1].
At least a couple more weeks. Hopefully less than a month out from now.
I have most of the UI done for sequencing. Workflows for speed building and metronome sequencing will be completely free, which is also a top priority for me to get out the door first.
I got tired of Spotify recommending me the same songs, from the same artists, over and over again.
So I built Riff Radar - it creates playlists from your followed artists' complete discography, and allows you to tailor them in multiple ways. Those playlists are my top listened to. I know, because you can also see your listening statistics (at the mercy of Spotify's API).
The playlists also get updated daily. Think of it as a better version of the daily mixes Spotify creates.
I still am not sure exactly how to define it, but it's a ruby library, that is mix of a rules engine+spreadsheet feelings+array language+static validation+compiled/codegen... that last part is mostly not merged yet but yeah, ruby DSL codegenerating ruby, it's ruby all the way.
https://github.com/amuta/kumi/tree/codegen-v5
(see ./golden for more context on the compilation/codegen. I barely knew what a compiler was before doing this so I might have just created some nonsense )
Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here's a tarball containing everything" to "here's 500 packages", with resulting changes in the build process, download/update mirrors, installer, etc.)
Given that this is a major release, there are fairly wide error bars on that; it could be as much as 3 weeks earlier if the first release candidate turns out to be perfect, and of course it could be later if things go badly (but I very much hope to get it out by the end of 2025).
Definitely a massive job. Some FreeBSD developers have stepped up to volunteer tremendous amounts of help (and also the FreeBSD Foundation has paid staff helping out with parts of this) but my best guess is that I'll be spending around 300 unpaid hours making this release happen; I've been doing pretty much full time hours on this in September and I'm really hoping that once pkgbase moves from "need to implement the stuff which isn't implemented yet" to "need to iron out some bugs" I'll have time for other things... like my paid job, Tarsnap.
Very much a hobby, but I'm working on a Pinterest alternative built on ATProto called Scrapboard[1]
The Bluesky ecosystem is a really great platform to build social media on and with Pinterest being overtaken by AI content I figured I'd give it a shot. There is definitely not as much content there, but it is of much higher quality and the culture of providing alt text on images really makes search work rather well.
I'm working on ScaleDown [1], a context pruning API.
So over the past few years, I have seen how contexts have been steadily growing in AI apps. And while the context lengths of LLMs have also been increasing, they are still effectively about 200k tokens. The performance drops off a cliff after that (you might have noticed it as well with long AI chats).
It is a simple API that prunes away irrelevant parts of a context for a given prompt, a.k.a. context-aware pruning. Integration is super simple: just an extra API call before the final LLM API call. You can get an API from the website.
I would love to chat if this is something that is relevant to you and if you have any feedback on what we are building!
I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long.
For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that.
I think people feel that this is a poor match for how money works. So they improvise. And because we tend to not discuss money with others, they improvise on their own. What this typically looks like is checking their balance and trying to pace things.
I’ve been trying to design the app around that. Providing support to what seems like a natural, instinctive approach to managing money.
I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this?
And which cards / banks does it support?
Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.
Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion.
Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it's quite underserved at the moment.
In the future I may expand to other code-centric frameworks and more general game development topics, let's see how it go.
First time hearing about libGDX. Do you have any resources on why it's your favorite framework? It might be useful for your website as well. To sort of "sell" the framework to game developers who have not used it before.
libGDX is not in the same spotlight as Godot or Unity but still popular within Java devs circle.
I'm not aware of any resources explaining the "why libGDX" but here are some differences, speaking from my own experiences:
- Code oriented development, no authoring tool, no drag and drop, just you and the API, which might attracts traditional devs who prefer a pure coding approach.
- Very thin abstraction over the platform graphics layer, it just adds a few more drawing APIs over the underlying graphics API (OpenGL and WebGL). You’re free to build your own abstractions on top of the core APIs.
- Java, while might be verbose, is very stable, easy to learn and has huge ecosystem. Or you can just use Kotlin.
- Once you learn the ins and outs of the framework, it actually has a greater sense of freedom compared to Unity, Godot, Unreal, etc because those engine always force you to do things in their own opinionated ways.
I’ve been working more on the unit economics of my data union/trust idea (https://wherelabs.info/).
What I’m trying to understand is whether it is viable to pay people ~$5 per week for sharing their location data and demographics based on a 90% share of revenue from sales of data products built on that data. (But without ever selling or exposing individual level data).
I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease.
Are you making a joke, or is there some use for that? (I would think of all species on earth, chickens are the easiest to get eggs for once you exclude the insects, but lack of domain knowledge means I could easily be missing something)
Not OP but I think there are a lot of people (maybe mostly vegans) who would be interested. I have no thought on whether it would be financially viable.
I'd be interested just because I'd rather use non-animal alternatives if available.
I hope lab-made milk becomes a viable thing even though I'm not vegan or vegetarian. Lab-made eggs would be good too.
I'm working on an audiobook service (currently for myself) that will fill in major missing features for platforms like Audible.
- Ignore AI voiced books
- Show me unread books in series that I have in my library
- Experimenting with better search. I have experience with building semantic search systems and have been highly disappointed with Audible's extremely sub-par search capabilities. I want results that are actually based on books, authors, and narrators that I have already purchased, read, or listened to.
- Get automatic notifications when new books from authors and narrators that I subscribe to become available.
There's at least a few more gripes I want to address, but these are the high priority ones that come to mind right now.
My biggest issue these days, is that after spending 1000 hours messing around in eleven labs, almost all female american audiobook narrators sound AI generated to me. I feel like as a demographic they must have sold a lot of voice recordings to the platform for analysis. I have DNR'ed a few audiobooks recently due to this.
I've been making and selling my electronic social battery pin badges for a while now (https://hortus.dev/products/social-battery) and I'm expanding the range with seasonal versions like a Christmas mood badge, and a halloween themed ghost badge that's coming soon. I'm lucky enough that these projects have gone down well and are making enough money to fund some more complicated (and expensive) projects that I wouldn't have otherwise had the guts to try. Currently I'm working on an RGB digital sand timer with customizable timing sequences so that you can use it for things like the pomodoro technique - I have a working prototype and at the moment I'm experimenting with interfaces for setting the sequences. I wanted to use a combination of buttons and an accelerometer for this but it's not as intuitive as I'd like so I may end up making a small smartphone app to configure it.
I pride myself on being pretty well organized with my digital life, especially files and folders. I’ve been using Hazel (God Knows, since it's beta). Recently, I realized it has become a muscle memory for me to name/rename files, and drop them where they belong while I'm working on or as it happens. This works for me now because I have a weekly routine of digital chores that picks up any slack and missing things that I missed during my days. Compound this with the fact that I have reduced a lot of clutter, minimized things that I’m involved in. That worked. I did away with Hazel since the beginning of 2025 and I didn’t missed it.
However, I’ve been sheepishly and shamefully looking at either an AI-assisted solution to even do away with the last mile cleanups and organization that I do.
Your text above is good enough marketing for me, and your website’s content sealed it. Didn’t even look further. I’m your customer now. And, personally, have always loved supporting other founders/builders building interesting tools and utilities.
Edit: I just realized this is not compatible with Intel Macs which I wanted to use on too. I didn’t read everything on the website, did I?
Suggestion: Please send me an email after successful purchase, so I have a record.
This might be what I've been looking for. On the first of every month I have Hazel put everything in ~/Downloads/yyyy-mm (previous month), with the intent to move each file to the correct project/area folder in my actual file structure. But I'm about 1.5 years behind on that...
Have you looked at competitors? If so, what are they? I haven't found anything that does this as elegantly as Fallinorg.
I'm working on Macscope (https://macscope.app), a better Cmd+Tab for macOS. I built it because macOS window management feels slow compared to the keyboard-driven speed of a terminal or code editor.
It augments your existing muscle memory: a quick tap of a shortcut switches apps like normal, but holding it opens a powerful interface with features like:
Unified Search: Instantly find any window, app, or browser tab.
Scopes: Save and restore entire window layouts for different projects (perfect for after you unplug a monitor).
Placement Modes: Snap windows to screen halves as you switch to them.
The goal is to make the OS feel as fast as my other tools. I'm always looking for feedback on how to make window management less frustrating!
I’ve been building Flare (https://www.getflare.app/), an app for people with chronic skin conditions (eczema, rosacea, etc).
It lets you log symptoms and triggers, but the bigger vision is being able to discover patterns, ask questions about your own data, etc.
Being able to answer questions like “Do my flare-ups correlate with stress?” or “What foods make things worse?” backed with personalized data has been helpful with my own flares.
Still early, but curious to hear thoughts from folks!
It annoys me how much a bad trailer can spoil the movie, so I made this platform to rate trailers how "spoily" they are and how good they are. To my surprise, you find some great trailers without many spoilers, but then you will have trailers which are basically a 3-min summary of the movie.
Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!
I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)
As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.
I am working on FastFileLink (https://fastfilelink.com/), yet another file-sharing CLI/app that uses WebRTC for P2P transfer but exposes HTTPS links, making it compatible with browsers and tools like curl/wget.
It's ~90% production-ready. We use it internally to move files between containers and hosts (especially when volumes aren't mounted), and for WFH employees to exchange large files without a relay server.
For huge files, there's resumable upload to our infra-backed server — fast global downloads included.
The CLI will also support receiving files via WebRTC, but that feature hasn't been released yet. It is open source (https://github.com/nuwainfo/ffl), but the README hasn't been updated yet and the code is not synced with the latest version (working on these).
Another production-used tool I'm working on is
MailTrigger (https://www.mailtrigger.net/) — a programmable SMTP server that turns any email into a message on LINE, Slack, Teams, Telegram, SMS, or basically anything.
If your app can send email, it can trigger multi-channel notifications with zero extra code.
Think of it as “SMTP to Anything,” or an email-native IFTTT/Zapier.
It supports JS and WASM for preprocessing, routing, and automation — you can write custom logic, auto-reply with LLM-generated messages, or forward alerts intelligently.
We use it for price drop alerts, server health monitoring, and integrations with Jenkins/Sentry to push incidents to our DevOps Telegram channel.
Also experimenting with LLM-assisted rule creation: you can define notification logic in natural language instead of writing code — for example, auto-reply with an LLM-generated joke or handle customer support queries dynamically.
Docs are more complete than the website (which is still evolving), and the pricing page is currently a placeholder.
Already running in production for us and a few early adopters.
I’m building a daily word puzzle game with a twist!
In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword.
You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got.
I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every day!
So far I’ve gotten really positive feedback and have around 100 people signed up to get notified. It’s been a lot of fun to build!
Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once.
That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.
Working on a personal recruiter / talent agent for my smartest dev/product/design friends (and theirs) https://www.hedgy.works
Key problems we're solving:
- Everyone wants to be doing meaningful, fun work that feels like their "life's work". Few feel like they are.
- In recruiting, the AI spam problem is real and only getting worse, essentially killing the cold application pipeline. You need a referral.
- Optimizing your career feels like annoying politicking for a lot of the most talented folks who just want to focus on building cool stuff. But, as an employee, if you don't test the market (e.g. take a recruiter conversation) from time to time, your comp can really stagnate.
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!
Sumo fan here, this is cool. UI is great. I assume you know about sumodb? I don't say that to discourage you, but people are tracking stats.
Since you are good at UI, here's something I would really like: a Natto-style page for each bout that I can manually page through as I watch the basho. Since Natto is underground, I have to watch the basho on NHK or Abema or via Kintamayama - all fine, but I miss the Natto graphics. If you could do that in a way that I could tap through each match, I'd use it every day of the basho and I think so would everyone on r/sumo.
BTW if you don't know what I'm talking about, reach out and I will explain.
I was testing something like this with https://sumostats.com/live (a second-screen style page, so you can quickly look up the current match and it follows along live).
But I think I know what you mean... I'll check out Natto graphics again (haven't seen it in a while) and will try make something up for next basho!
Continuing to do a lot of historical review of early AI stuff. Just finished the Semantic Information Processing[1] book edited by Marvin Minsky, and now I'm reading Volume 1 of the Parallel Distributed Processing[2 book by Rumelhart and McClelland. After that, I have Principles of Semantic Networks[3] by John F. Sowa queued up.
Along with all of that, still working on a lot of stuff using Jason[4] / AgentSpeak[5]. I created a fork[6] of Jason that is meant to be easier to integrate with Spring Boot, and to take more of a "run headless on a server" approach, which meant taking out references to a Swing based in-process logging/management tool. In place of that, I'm implementing a JMX based management interface, and recently I've started to work on replacing the old Swing app with a JavaFX app that can connect using JMX Remoting.
It's funny you say that. I already do run a weekly "book club" group, but it's at work at my $dayjob employer. And, for various reasons, we've drifted away from the book focus and turned into a more presentation/discussion oriented group. But I still love to read physical books, and wouldn't be opposed to trying to come up with something to structure some discussion around some of these "outside of work" readings that I do.
If you want, drop me and email (prhodes@fogbeam.com) and maybe we can set something up.
I'm trying to make an RF lightning detector small enough to trivially add to my motorbike.
I live in Viet Nam, and driving through bad storms this time of year is pretty miserable, and they happen fast and are local enough that weather prediction is not terribly useful.
There are a lot of problems with EMI. Lots of ungrounded brushed motors everywhere that make the RF bits hard. If I succeed, I'll publish the PCB designs.
I've also got some educational products in production right now, about Vietnamese history. I'd share a link, but my website probably can't handle the traffic right now.
Tech side project: crawlers that doomscroll job boards for me, and a Tinder clone that swipes through them. I recently broke out the actual automation logic into something more recyclable for scaling out to new targets (and broke out the HTML parsing for possible use outside my browser automation flow). Still figuring out how I want to handle datasources as both an API and a plugin architecture, but the goal is to eventually be able to configure searches through the API, to manually trigger and/or setup scheduled runs.
Personal side project: extensive cleanup of my family's place. I'm just now approaching a decent first pass at the outside, and have to tear apart a basement next. It's taken most of this year. It's not the specific reason I've farmed collecting search results off to a bot
For-fun thing: CTF puzzles. I'm not very good at them, but they're useful for other things. I fell down the scraping rabbit hole this way, and I'm currently using a series of them to finally get some exposure to Python. I also have a writeup half-written about this exact process
I'm working on Pruno (https://pruno.dev/), it's similar to Dependabot/Renovate bot but it removes dependencies instead.
My team suffers from dependency creep. As soon as your system grows, the number of dependencies skyrockets. In Python/Javascript projects it's especially hard to determine which dependencies are not used anymore.
Pruno saves time for your team by automating this work. It's still WIP, but I'd like to get feedback. How are you dealing with your dependencies?
I'm working on a bunch of small tools for musicians. I want to simplify complex musical concepts by giving visual feedback and minimal UI. All modular components built with pure JavaScript.
Continuing to build https://crucialexams.com/, a platform that helps people prepare for IT certifications like CompTIA, AWS, and Microsoft/Azure. It offers realistic practice tests and study tools. I also have partnered with educators and universities who now offer it to their students and get dashboards to review student progress and identify where they are struggling.
It's been a while since I've used CloudWatch myself. How would you expect this? IE would you lean more towards having a lambda/firehose that forwards events to to the API (which is [public](https://tailstream.io/docs/api) by the way!) or would you expect some kind of agent / connector to run that automatically pulls the logs from CloudWatch?
I've been contributing to a project called Folk computer[1]. It's focused on creating a physical medium for computing (think printing out a program, which is then tracked by the computer. There's some really cool spatial interaction that happens). Folk v2 is currently in development, so I've been digging into the guts of the datalog-like engine. It's been a lot of fun to pick up C and see it applied to a project I can directly interact with!
My one man side project is Prisme Analytics: an high-perfomance, self-hosted and privacy-focused web analytics service.
I'm working on improving UX and simplifying deployment a lot. In the next release, a single docker run will be enough to get a working web analytics service with minimal resource usage.
I'm building an app to help people memorize Kanji by turning the characters into vivid, memorable images with accompanying mnemonic stories.
I think AI image and video models have reached a point where they can offer a completely new approach to language learning.
Next, I'm planning to add features that use AI to generate comic strips (using Seedream or Nano Banana), songs (using Suno) and videos (using Veo 3 or Seedance) to make learning Kanji even more engaging.
Solo-building this project for some time, going to launch the first version in a week or so!
https://elmo.dev - a tool that automatically builds a searchable knowledge base around your project based on your conversation with coding tools.
It works automatically and doesn't require your attention. To build KB it uses same tool as you (claude/codex/gemini) so it uses the same quota and you don't have to pay additionally for the AI running it.
The result is ./elmodocs directory in the root of your project. You can reference CLAUDE.md/AGENTS.md/GEMINI.md to this directory or directly include the whole directory or its parts into the coding context.
I'm finally organising 20 years of voice notes. Some were quite outdated - I probably no longer need the mozzarella cheese I reminded myself to buy in early 2008.
To organize them, I'm writing a Python Qt application with Claude Code. It started off as vibe coding, but I'm now developing it using processes very similar to those I would use when managing software teams. I've picked up a lot of good tips about that here on HN. I've got Whisper, and fallback online services, transcribing the audio and summarizing it and adding tags. After much UI experimentation, I've landed on something that looks not unlike an email client, with tags in the left pane, a center pane which lists transcriptions and notes about each audio file, and a right pane with more detailed information about the selected audio file.
Next step is to serve it all as a model context protocol server - I need to pick an agent.
We are working to build Notion, but for books. It is a personal book diary to collect your to-be-read and smart sort them, as well as log your reads and use that data to build a profile of your book dna in order to connect you with new books/authors that your book twins love.
Fluxmail is an AI-powered email app that helps you get done with email faster. I think there's a significant opportunity for AI to change the way we use email, and I'm experimenting with ways to improve the status quo. I'd love to hear what features you'd like to see in such an app!
This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.
I built a fantasy football rankings app using claude code, and it has been blowing up in the fantasy football subreddit. Funny enough, it's forcing Yahoo to change their site and improve their layout which ruined all my automation. Surprised how much traffic it's receiving every week just for a better layout.
I've been building https://resolver.one - a DNS server that returns GeoIP data as TXT records. Query an IP directly as the hostname (e.g. dig TXT 8.8.8.8.rslvr.one) and get back country, ASN, etc.
Always been fascinated by repurposing established protocols for unintended uses - DNS is everywhere, passes through firewalls, and has built-in caching. Seemed like a fun way to deliver location data without HTTP APIs.
Super niche, definitely a bit odd, but that's the appeal.
Data source is IPinfo Lite MMDB file, which seems to be offered freely without restrictions. I'd love to offer comprehensive GeoIP attributes but I'm afraid to even ask how much the DB download of that costs... I'm working on supporting new data sets now like security CVEs, shodan integration, etc.
It started as a solution to LLM front ends having terrible native branching features. But slowly I realize most of our data will be going through LLM's so Yggdrasil is evolving into a platform which consumes all your LLM queries, while keeping it easy to query and reference.
And now I have begun to realize how detrimental LLM assisted coding can be to someone who starts depending on it too much, so Yggdrasil is a bet in the other direction as compared to mainstream. Instead of agents/AI doing everything I believe human + ai assistance will win in the end.
Yggdrasil has a simple agent called Valkyrie, so they have their place, but that I believe should be the last step, after the developer has discussed and planned thoroughly through our tree interface, Heimdall.
And if someone replaces the dev, they can browse their conversations with the LLM, observe their mind map, what questions they asked, what extra things they considered (branches), the whole thought process easily navigable and visible.
Personally after using Yggdrasil, I feel quite confident in using the LLM, as I can ask all the silly questions I want, without worrying about context pollution. It aligns really well with the natural exploratory tangential thoughts we have when trying to find solutions or learn something.
I am building LookAway[1] - an antidote to seductive screens. Many people have been facing issues like eye strain, digital fatigue, CVS, posture issues, and more due to prolonged screen use and I aim to solve it with this product. I believe managing screen time is as important as managing sleep (if not more).
As someone who's curious (I see lots of room for improvement in terminals!), I can't tell what this does from the website, other than the ability to load and view 3d models.
A webscraping / data pipeline to get the .pdf "Explanation of Benefits", "Proof of Coverage", and "Drug Formulary" for every Medicare Advantage plan in the USA
These docs are gonna be used in a product for medicare brokers (if you are/know one please reach out open enrollment starts Nov.1!), and the pipeline is horizontally scalable to ingest updated 2026 plans overnight @ start of open enrollment (though some companies are posting updated plans earlier)
There are some clever tricks at play but mostly it's bog-standard browser automation; I'm also in an interview process with 2 entities (one funded startup and one massive corporation) talking about web automation roles, and while it's frustrating that they're moving so slowly it's working out to give me time to build this well.
Trying to re-legalize "neighborhood commercial" by right in the city I live in. Things like corner stores or small barber shops or coffee shops or converted restaurants. ACUs or Accessory Commercial Units, home conversions... different ways of doing it.
Great. I assume you live in the US ? Your urban planning law are atrocious. In countries like thailand for instance it's very common to have a shop in the house. Things go nicely and it's more lively. Good luck, that a good project at the root of so many issues
If you have a shop in a house in Thailand and a crazy person decides he likes the shop and stays in front of it all day yelling, in Thailand, the people in the house call the police, who make the crazy person leave. In the US, every person, crazy or not, has Freedoms and Rights, and the police won't do anything to help the people in the house because it would be wrong according the the US way of thinking to curtail the Rights and Freedoms of the crazy person (who is yelling all day near the shop, which is very near the house).
Consequently, owners of houses in the US try to make it as boring as possible and as useless as possible for any crazy person, homeless person or group of teenagers to hang around near the house. One way they do this is to make sure the house is surrounded only by other houses, trees, parking spaces and roads (and there is not anything as useful or interesting as a shop in easy walking distance).
This is a bit of an exaggeration, but it is directionally accurate.
No, it's mostly just car-brain where people think that cities should be designed around cars cars and cars, and then if there's room left over, maybe some shops and homes.
So they worry about a neighborhood shop taking up the precious, precious parking spots or causing 'traffic!' even if in reality it reduces it because people have something close by their home they could even walk or bike to.
So the root problem is not the American commitment to rights and freedoms (especially for the disadvantaged) that Americans discuss constantly -- often in heated, emotional or abstract terms and sometimes in frankly ideological terms. According to you the root problem is an irrational and destructive commitment to automobiles, which (at least after the 1960s) Americans talk about much less than they talk about rights and freedoms -- and
when they talk about them, they talk mostly in pragmatic terms, e.g., miles per gallon, turning radius, maintenance costs and space for car seats for children.
I live in a city of 100K people, where there really aren't that many visible people with mental health issues or drug problems. I also go to a lot of city council meetings and hearings and observe local social media.
I recently released JazzEar, an iOS app for ear training. Specifically focuses on improving recognition of chord progressions you would hear in jazz standards.
Now I'm working on a smaller app for jazz musicians to manage their tune list and act as a tool to help practice and review tunes. I wanted this app to tell me what tunes on my list I haven't played in a while (and might forget), or try different keys or exercises on the tune and track what I found difficult.
I left my job to work on my side project (MCP-B: https://news.ycombinator.com/item?id=44515403) full time. I set out with the goal of making the ability to vibecode a webMCP server for your website and inject it via userscript.
While building that, I basically wrote a modern version of Tampermonkey with its own marketplace built in. So you can vibe code any userscript and publish it to the marketplace all within the extension.
The automation stuff is still the core value-prop, but this is a fun bonus feature while I work on solidifying the automation features.
I'm writing a HN post for it. Excited to show everyone in a couple weeks here.
After that Deus Ex remaster fiasco, I wanted to see how the famous Unreal 1 dithering technique would look on Quake's software renderer. Getting a clean build of it on Linux was fun in itself: https://github.com/klaussilveira/exp-quake
I'm still working on Danger World (https://danger.world), my casual 2D narrative adventure with turn-based RPG elements. Built in Flame, on top of Flutter for iOS, Android, Windows and MacOS.
We're getting close! It's just a matter of polishing and polishing and polishing, but I'm really excited about how close we are to launch.

Been thinking a lot about tools for modern musicians/artists/producers. Not tools for creating the music but tools for communication. Email subscriber lists, event creation (image and text) combined with ability to generate QR codes and send them with easy to use dashboard, some kind of insights into the QR scans, merchandise (integrations with Shopify), hn style link aggregation around music.. been building it with my son who also becomes my product manager since he the one using the tools. For now a private repo consisting of a rails API and a react TS frontend app. Everyday I come up with some small improvements in my head but alas not enough time in the world. With the day job an all, this is purely a passion project and a way to help my son follow his passion, putting on house music events and DJ/producing. If anyone interested, plz reach out contact@kushtybuckrecords.com
- Active recall studying app that allows a user to practice active recall[0]. The app hides user provided content at first and asking the user to try to remember all they can before reading the content. Then the user goes through the material slowly revealing each paragraph from their input. At the end they try to actively remember what they learned and can even compare to what they knew at the start.
- Mixtape sharing platform for midwest emo[1] which is a genre I've really gotten into over the past few years. The community is pretty strong on YouTube for creating "mixtapes" so I wanted a spot that was just for these videos.
- PhotoForge[2] Photographer's companion app which can help me choose photos using a Tinder-esque swiping mechanism. It also has some AI stuff for generating Instagram descriptions. Finally has a watermark tool. Still trying to think of other stuff to add. This was an AI code weekend project so it's like a house on stilts at the moment but I plan to give it some more love soon
I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1].
It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integration.
I posted about it[3] on Last FM's subreddit and I was pleasantly surprised to see that a lot of people shared their labels on the comments and seemed to like it.
I'm currently working on language detection, I think it'd be cool to get a language breakdown of the songs you listen to and for that to be part of the displayed items within the label. Something along the lines of EN- 80%, ES- 15%, FR - 5%
I've also tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up")
Typing is an extremely underrated skill and especially in the age of LLMs, it is the bottle neck in a lot of cases.
I’ve never been fond of existing typing apps; excessive ads, typing random words, etc so I built my own.
You can practice typing code, use your own text, etc
We have a paid plan for features where you can type natural text that targets your weak points (via SmartPractice) and many others. Other than that, it’s both free to use (and ad-free)
I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard.
Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job monitors), I'll be able to start building a proper terraform provider, and audit logs.
Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer
Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things.
Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of hints (know of UK, Norway and might have found for France).
I've been working on a map that shows which neighborhoods in a city are nice/not nice with a short description.
Whenever I visit a new city, just looking at Google Maps is pretty meaningless - it's just a bunch of gray land and streets. I end up looking up Reddit posts for where to go, searching for crime maps, trying to find annotated maps, etc. to get a better idea of where to visit in a city (or even live, like when I had moved to Austin). AI generated scoring and descriptions, while imperfect, have already helped me when visiting SF recently. Early stage, so please help with submitting corrections, if you'd like!
I like the idea! In my opinion (looking at SF) it’s still too low resolution. SF in particular can vary greatly in safety, walkability, etc. even a few blocks over within a neighborhood.
Very cool! I really like the idea, the way I'd develop this further is by having live crimes reporting on it so that you know which streets to avoid , similar to what waze does where people report items
Most of our jobs consist of working with tools. Yet it’s very hard to get insights into which tools are required most, are growing in your area, etc. So I decided to keep track of tools and technologies mentioned in the data space by keeping track of job openings for the last two years. Now I’ve opened up that data set. Here’s an analysis for jobs per data warehouse: https://selectfrom.work/insights/data_warehouses
I’m currently hacking away at a project which turns your keyboard into a clipboard manager, password vault and barcode reader as parts of it. I just need to come up with a better name than totally normal keyboard (:
Inspired by a friend getting a random email and it sparking a memory for me: https://pageday.org, a global message lottery where each day a random message is drawn to be the homepage.
Yeah that's a good question, and something we haven't codified.
Odds are that we'll curate quite heavily to keep it interesting and maybe along similar guidelines to hn with "anything that gratifies one's intellectual curiosity" rather than just "anything".
Mostly organizing my dotfiles across Windows, macOS, Linux and BSD, however, I have really fallen for Ansible. I discovered at work awhile back, but was able to grok how to make and run a playbook, and I've been hooked since. It also finally allowed me to click the difference between Imperative and Declarative programming!
I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output.
The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.
I'm trying to build a next gen quickbooks competitor.
Something that doesn't nickle and dime you, very cheap (perhaps even open source), has all of the extensibility of a modern ERP, a great UI, and handles complex use cases (revenue rec, expense management, inventory cogs, etc).
I feel like this is solving a real problem, but have no idea how to break into the industry. Just trying to solve my own problems for business accounting but would be nice to know other folks would be interested.
Oar, a GitOps Continuous Delivery tool for Docker Compose. Think ArgoCD, but you don't need or want all that Kubernetes complexity.
https://github.com/oar-cd/oar
I'm trying to incentivize people to build IRL communities instead of AI-related apps because the demand for human interaction FAR outweighs the supply. My platform (https://onthe.town), is basically Shopify for social experience clubs. Anyone can start a club and create events based around bringing random people together IRL based on shared interests. You get your own website and infra that handles signups, payments, and matching.
It's largely based on platform-izing the extremely popular Timeleft app that simply matches 6 random people for dinner. With onthe.town, anyone can create a Timeleft-like app around any concept they're interested in. Some clubs people have created include a golf club (get matched with 3 other people to play golf with), a vinyl record sharing club, a lunch club for biotech networking, and a club to meet other parents for dinner.
There was a startup in my region who got popular with the simple idea of having a website/service that manages simple events, like talks, presentations etc.
I think it started with mostly students using it because there used to be a lot of university-related events like these, and eventually they’ve become the standard platform for that, at least in the State. It was all pretty simple, it managed payment etc. and you’d get a QR code by email or in the app that could be scanned in the entrance.
I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made up of jobs that declare their input and output partition deps, so that they can be automatically fulfilled, enabling kubernetes-like continuous reconciliation of desired partitions.
This means, instead of the answer to "how do we produce this output data" being "trigger and pray everything upstream is still working", we can answer with "the system was asked to produce this output data partition and its dependencies were automatically built for it". My hope is that this allows the interface with the system to instead be continuously telling it what partitions we want to exist, and letting it figure out the rest, instead of the byzantine DAGs that get built in airflow/etc.
This comes out of a big feeling that even more recent orchestrators like Prefect, Dagster, etc are still solving the wrong problem, and not internalizing the right complexity.
Very much agree that to this is the direction data orchestration platforms should go towards - the basic DAG creation can be straightforward, depending on how you do the authoring - (parsing SQL is always the wrong answer, but is tempting) - but backfills, code updates, etc are when it starts to get spicy.
I think this is where it gets interesting. With partition dependency propagation, backfills are just “hey this range of partitions should exist”. Or, your “wants” partitions are probably still active, and you can just taint the existing partitions. This invalidates the existing partitions, so the wants trigger builds again, and existing consumers don’t see the tainted partitions as live. I think things actually get a lot simpler when you stop trying to reason about those data relationships manually!
Clicking items in the tensors explains where they came from and where they are used in the output. The input tensors can be modified too.
It's a one-man side project that's been half building the site framework, and half re-implementing pytorch functions in javascript. Plenty more functions to go, but hopefully people can already find it useful. I'm planning on doing a Show HN once I've added ~10 more functions.
Posting this from a throwaway account because my main account is locked due to `noprocrast`!
I’ve been working on a few utility libraries to make it easier to develop web services, basically exporting packages that I find myself using or rewriting often and exporting them as their own modules.
I’m working on https://github.com/hxtk/aip as a collection of libraries giving safe default choices to implement Google’s API improvement proposals in ConnectRPC services. It borrows (with attribution per the license) an unexported implementation of AUP-160 filters from the LuCI project, and I intend to expand it to support data sources other than SQL databases and page tokens, and it also exports an implementation of AIP-161 field masks (which have different semantics compared to standard field masks) and middleware to help with using them for AIP-157 read filtering. I intend to export more middleware that I use frequently, but I don’t know if it’ll live in this module or its own yet.
You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.
I'm putting a bunch of security tools / data feeds together as a service. The goal is to help teams and individuals run scans/analysis/security project management for "freemium" (certain number of scans/projects for free each month, haven't locked in on how it'll pan out fully $$ wise).
I want to help lower the technical hurdles to running and maintaining security tools for teams and individuals. There are a ton of great open source tools out there, most people either don't know or don't have the time to do a technical deep dive into each. So I'm adding utilities and tools by the day to the platform.
Likewise, there's a built in expert platform for you to get help on your security problems built into the system. (Currently an expert team consisting of [me]). Longer term, I'm working on some AI plugins to help alert on CVEs custom to you, generate automated scans, and some other fun stuff.
https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a proper accounting foundation.
It's a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Soon with multi-currency support. Currently targeted for desktops.
It's interesting in many way. Using double-entry (it's a perspective shift and a power tool), the challenges and advantages of building local-first app, UI/UX & visualizations, privacy and more. For personal apps, local-first is a good fit.
Tinkering with a tiny macOS app that gives me proactive reminders about the low battery and imminent shutdown.
Standard system notification comes at about 10%, and most of the time, in my case at least, whenever I miss that, the result is "laptop shutdown amidst an ongoing video meeting" or something like that.
(Basically, too late before I act)
Just so that I don't miss the reminders, the app will show an overlay window with some text, following my cursor, and a custom sound.
I vibe-coded a version this weekend and can see it being helpful already [at least to me].
I'm actually in the middle of a complete redesign of the AI layer, but there is a POC video linked from the GitHub README that demonstrates the interaction I'm going for using an earlier version. The POS is a very bare-bones system where the "kernel," as it were, is implemented in Rust. There's an MCP atop that to allow the AI and UI layers to drive the POS. Stores may be implemented as extensions that plug into the POS kernel, and that's where language, currency, item databases, and such are defined. The AI cashier knows what items are for sale, how to modify items (in a restaurant context), how to translate from other languages, how to interpret what the customer actually wants, and seamlessly lead the customer through a transaction.
The current code is quite ugly and full of a lot of unfortunate hacks, but it was a good education. The new design puts the AI much more in charge, without as much code-level orchestration. I'm applying a lot of my knowledge from the retail POS and self-service checkout domains to this, as well as learning a lot about applying AI to a "legacy" software domain.
Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types.
Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Would love feedback!
It's not the core of koda-validate, and yeah lots of libraries have a similar capacity. Feedback I'd be interested in is if there are gaps.
In general the value prop of koda-validate is that it turns validation into typesafe building blocks, which makes validators very re-usable -- and flexible. Some other notable differences from pydantic are that it doesn't `raise` on validation errors, you don't need a typing plugin, and it's fully asyncio-compatible.
An open-source protein/molecule viewer, molecular dynamics sim, and general structural biology toolkit, written in Rust. And an ecosystem of libraries to back it up.
I have made a Bürgeramt appointment finder. It was down for a few weeks after the city of Berlin changed its anti-bot measures. I just released an updated version that works again: https://allaboutberlin.com/tools/appointment-finder
My citizenship wait times page (https://allaboutberlin.com/guides/citizenship-wait-times) has also gotten enough feedback to be useful since its release last month. I'd like to make it more useful with better visualisations.
Now I'm working on another iteration of my health insurance calculator (https://allaboutberlin.com/tools/health-insurance-calculator). It's kind of a big deal both because it's a huge financial decision for recent immigrants, and because it funds a big chunk of all the free stuff I'm putting out. This is especially important with ChatGPT and AI summaries halving my traffic. This iteration will recommend health insurance combinations that work for a visa application and for a long-term stay in Germany. It will provide far better explanations.
At the same time, I'm testing a new insurance broker with far shorter response times, so people can directly ask an expert to help them choose. They're reachable via Whatsapp, and that made a huge difference in how people get advice. It worked so well that I want to do the same for other topics. I'm already talking with an immigration lawyer who's interested.
I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.
I might be taking a contracted job to help provide AI/ML guidance for a friend's company here soon, but all I really do is use ChatGPT/Claude Code a lot and don't really have explicit AI/ML tool building experience. They know this and mostly just want me for competency and comfort going from 0-1 with a new project, but I'm still pretty nervous! So I'm trying to conjure up some simple ideas to inspire me to learn :)
Currently trying to predict student absenteeism in the future based on historical indicators with synthetic data using basic ML modeling and then using LLMs to generate helpful guidance for relevant parties. Basically letting parents know there's concern and citing leading indicators.
Not sure what I'll do next, but hoping to come up with a few other ideas to put my mind at ease. It's fun having some actual motivation to keep up with the current hype instead of just being a consumer, though!
I’m working on https://www.hessra.net/, an identity + authorization service built around [Biscuits](https://www.biscuitsec.org/) instead of JWTs. The goal is to decompose auth primitives so they’re easier to use in service-to-service cases, while also showing off what Biscuit tokens make possible.
JWTs feel like problems waiting to happen. I think biscuits give stronger guarantees and are harder to get wrong.
One piece I’ve shipped is an identity token that can be delegated offline. For example, “company:alice” can delegate to “company:alice:agent,” and that token can then be used to request an authorization token. This makes for a neat API key model: you can issue a simple opaque identity token to your customer (e.g. “customer123”) without having to maintain a DB of hashes/expirations, since those are encoded into the token. Later, you can upgrade security by exchanging the identity token for an authorization token, or let customers delegate access (e.g. “customer123:marketing”).
I’ve also been experimenting with higher-order authorization flows:
• Service chains: each step in a request’s path (edge → app → DB) can add attestations, so later services can validate the full chain.
• Multi-party authorization: requiring two independent services/orgs to co-sign an authorization token, useful for cross-org or on-prem deployments.
Right now I’m building an OAuth 2.1 profile where the identity token replaces a refresh token and the authorization token stands in for the access token. I’m especially interested in hearing where people find OAuth clunky in practice, or stories from folks who’ve built auth systems with other token types (macaroons, biscuits, etc.) or for use cases where OAuth didn’t fit well.
Biscuits are in the same family as macaroons in that they are bearer tokens that can be attenuated offline, but they go further. A biscuit carries a chain of signed “blocks” that can contain facts, rules, and checks in a small Datalog-like logic language. That lets the token itself express richer authorization context, not just restrictions.
Key differences from macaroons:
- Crypto model: Macaroons use HMAC, so every verifier needs the shared secret. Biscuits use public/private keypairs so any verifier with the public key can check validity.
- Expressiveness: Macaroons only add caveats (restrictions). Biscuits can encode facts, rules, and checks, enabling more complex policies to travel with the token. so you can attest and attenuate (and do some other tricky stuff if you want)
- Delegation: Both support attenuation, but biscuits do it with signed blocks that are verifiable and can be chained across services.
So conceptually similar, but biscuits aim to be more decentralized and policy-rich.
On the side, I‘m building a platform that allows to run MCP servers on demand, making them reachable under a public URL, but password-protected.
You also get an embedded VNC viewer, and thus you can watch what an AI-agent is doing with it.
This makes it possible to use your own, dedicated MCP server instances from, for example, n8n workflows, without thinking about infrastructure.
I’m solo-coding the clear commercial project smmdealfinder.com which is not ground-breaking or amazing as these other great projects here, but its been an amazing journey for me personally for the last 18 months and has developed me probably from a junior engineer to senior+/staff.
Whilst I’m recently really critical of most AI posts here, this wouldn’t have been possible without AI, but mainly because AI could feed my curiosity and barely any riddle was unsolvable, when I put it into pieces and combined it with debugging (and checking docs). Actually most riddles on my level weren’t unsolvable before, but AI reduced the friction and speed of learning for me. This actually goes beyond coding. In life I just ask and learn a lot about, washing, cooking and domain-specific terms.
I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 .
There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just managing files instead of creating a new compose-like DSL. But even if it doesn't become popular I'm just happy I don't have to manage my homelab with Ansible anymore :) .
I'm working on a new type of git forge[1], optimized for speed and work with patches.
It goes to extreme lengths to ensure great performance, i.e. rewritten most server-side parts of git from scratch, so there is no "exec"-ing git nor calls to libraries like libgit2. The frontend should also be very fast thanks for HTMX.
There was "choker" back in the day, which I actually never heard about since I wasn't into chess back then. But (1) there was no web version, and (2) it had a specific gameplay that seems too slow for my taste. My version is highly customizable on the setup/rounds/rules, too. From my research, the original was also overrun by bots.
Looking up choker online I found this reddit thread:
> It’s a cool concept, but terrible app design and it’s all just bots you connect with, making it terribly easy to win almost every game
It sounds like this game needs a better AI opponent then? I don’t know anything about this game but something that learned from your gameplay and figured out how to beat you would be very cool.
I already have a better chess engine at different skill levels for 1-player mode. For two human players, I plan to start with sending a link to a friend given there won't be enough random players on the website to find one in real-time.
I am launching (tomorrow) a service that helps builders and businesses fix their vibe coded apps and get them production-ready and integrated into their organization:
Testing jig for a traction control system for a locomotive. Microcontroller connected to a DDS waveform generator simulates the sensor that picks wheel speed, various ADCs and DACs read in analog voltages that are compared to determine loss of traction. 1980s analog computing at its finest. If I had a choice I would be doing anything else ;)
I made my pops a walnut multi-guitar stand a couple months ago and I’d like to get some nice pics done and make one of those eCommerce web site things to sell them. Here's a bad pic https://bradlyfeeley.com/onokura.jpg
Also working on DailySelfTrack ( https://dailyselftrack.com/ ), an app to track what matters to you in a way that you find relevant. So it is a mix of habit tracker, health log and journal. Like a spreadhsheet app, but with much better UX. And like a habit/health app, but with much greater customization.
I want this to be a tool highly useful for people who have complex health issues, are working towards ambitious goals, or just want to regularly reflect on their day.
I'm building it since I couldn't find a satisfying solution anywhere. It's local first and does not force you into a subscription, or tries to exploit you with any other dark patterns
I'm working on exploring an exploit in physical security systems that I haven't seen anyone investigate before (at least, not published on the internet). It's involved an interesting combination of reverse engineering, pentesting and regular prototyping/hardware development.
Currently writing a run-through of it to publish on my website. I'm not sure how secretive to be - I think I just want to be the first to actually release my findings. In my post I'll detail the steps to reproduce my results so more people can look into this.
So far I haven't found any critical ways to (ab)use this access control system weakness, as it only typically applies to the outer layer of physical security.
Currently working on https://rudys.ai to publish and optimise Google Ads campaigns on autopilot.
The idea is to be able to publish campaigns globally in any location/language and also get qualitative recommendations on what to improve. For example, if people have typos in their search terms, Rudy recommends to add it as a keyword so it can maximise the conversion.
Yesterday I proved the infinitude of primes, which I was pretty happy with. https://www.philipzucker.com/knuckle_primes/ A trivial theorem in the scheme of things, but one for which z3 certainly can't do it on it's own.
I'm working on Happy Coder, an open source Codex and Claude Code native mobile app (plus a web app).
Happy lets you spawn and control multiple Codex/Claude Code sessions in parallel. Happy Coder runs on your hardware, works from your phone and desktop, costs nothing, End to End encrypted, and permissive MIT License.
Happy Coder is a unix style "do one thing well" project.
The goal is zero workflow disruption. I want to be able to run CLI coding agents on any internet connected computer, and control them with my phone. Happy has a command line wrapper for Codex and Claude Code that let you start a session in your terminal, and then continue it from your phone with real time sync. So type in your terminal and see it on the phone, type into your phone and see it in your terminal. So you can switch back and forth.
There is an optional voice agent some contributors have been hacking on that lets you talk to the voice agent first, and the voice agent then writes prompts for Codex/Claude Code and answers questions about what the coding agent running on your computer is doing/did. The voice agent feature is pretty neat, but in my opinion needs a bit more iteration, so any ideas or help would be awesome.
I’m building a text editor inspired by ed, but instead of editing files on disk, it edits live network flows. In this model, files don’t exist as static objects—they exist in motion.
Creating a file generates a self-sustaining pattern of packets circulating through the network, and editing it changes the flow itself. Multiple users can edit the same file simultaneously, because the file isn’t tied to any machine—it’s in the network.
The interface is familiar if you’ve used ed, with commands like append, delete, and substitute, but behind the scenes it’s all live traffic. You can even discover existing flows and jump into them in real time.
It’s a Linux proof-of-concept using raw sockets, and the goal is to explore what files could be if we thought of them as living, circulating processes rather than static storage.
I have been working on my terminal editor, but I parked that for now -- https://github.com/bloomca/love. It is possible to load a file and edit it, copy/paste works, you can select text, etc. The next step is to integrate with the tree-sitter for syntax highlighting and then with LSP, but it took a bit more time than I wanted.
Another project of mine is to play music from my audio CDs by myself. I built a simple Rust library to read TOC and raw PCM data from a CD drive -- https://github.com/Bloomca/rust-cd-da-reader (works on Windows, macOS and Linux), and a ripper -- https://github.com/Bloomca/audio-cd-ripper, which rips all tracks and encodes it as FLAC and fetches metadata from MusicBrainz.
The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.
Vibescape: an immersive meditation app. This one is currently featured at the top of the App Store, yay! Launched as a day one app on Vision Pro, new update has what I think is the best immersive environment I've made yet that comes alive with music: https://apps.apple.com/us/app/vibescape/id6476827678
I'm working on a Heroku / Render / Flyio alternative thats free, open source, built on top of Kubernetes for about 2 years now.
I’ve found these services charge way too much per GB of memory (10x more than IaaS providers), but more importantly, offer terrible flexibility. You can’t schedule multiple apps on the same instance, and there aren’t many instance size options.
Canine also supports deployments of any helm package (postgres, airbyte, dagster, etc) via helm charts.
I am working on my Go UI library called gooey [1] which aims to be a one stop framework to build webview/webview apps in Go and WebASM.
It started out with bindings for the DOM, Web, and Browser APIs, but as of today I now have custom Web Components support (which is a big deal considering Go's type system quirks).
Tomorrow I'm gonna polish some of the UI components and start refactoring my git-evac [2] repo management tool which is the first app using the gooey framework.
> Components are bad for web accessibility (aria- property fatigue).
I've been using web components as a vehicle to automate and auto validate accessibility aspects as much as possible, because I think the only way to truly make things sustainably accessible is to find a way to unburden the developer by either inferring as much as possible or making validation a natural part of development rather than a separate testing cycle that will invariably cause accessibility support to become out of sync.
It sounds like you might have similar concerns. Do you have any insights to share along these lines for Gooey?
The UI components that I wrote initially are just wrappers for the Browser provided input/form elements. As I'm relying on webview/webview to build desktop apps out of it, that also kind of implies WebKitGTK4 on Linux, WebKit on MacOS, and WebView2 (Edge) on Windows.
These work quite nicely together with a screen reader because you don't have to intercept the focus event (or others) that people browsing in caret mode or similar would use to navigate the page.
Additionally I decided to make single page applications using a main and section[data-view] elements so that the HTML and CSS alone is enough to hint screen readers on what's visible and so that there are no javascript codes necessary to tween things around, the JS/WebASM side of things literally just sets a data-view property on the main element.
The whole idea behind gooey and the way it is structured is:
- all states must be serializable in HTML
- Static HTML and CSS makes the page usable (apart from web forms and REST APIs, that's developer provided code)
- Dynamic WebASM on top essentially translates the DOM to be interactive, so that things can be animated based on changing data or streams coming from the backend. All interactivity is rendered directly into the DOM, so that it can be serialized again at all times.
- Communication between Client and Server is JSON or any other Go implemented Marshaller, and using Fetch API behind the scenes.
I decided on purpose to not provide XMLHTTPRequest and other old APIs because I'm relying on WebASM and "modern Browser engines" anyways. This way I kinda force users of gooey to use modern JS from the WebASM context and I save a whole lot of trouble with compatibility issues (and don't get into the unsemantic div fatigue like React does, for example).
The bindings should also work with tinygo's compiler if you're careful with deadlocks (see docs/ERRATA.md).
Haven't tested the typecasting that's required for the components yet though, they might break because of some generics quirks (e.g. Wrap/Unwrap helper methods).
I've been working on raytraced lighting in the Bevy game engine, using wgpu's new support for hardware raytracing in WGSL. The initial prototype is launching with the release of Bevy 0.17 tomorrow, but there's still a ton left to improve. Lots of experimenting with shaders and different optimizations.
It's a digital comic book store. Letterboxd with a buy button. It's really fun. We've got a lot of great publishers signed, and a great team. It's such a thrill to work in a space where people work their ass off to create art, in spite of the fact that the rewards are minimal. Our job, we feel, is to make them more money to make more art.
It looks like Markdown is having a bit of a heyday with it being the default mode of docs for AI coders. And it became apparent that there is no simple, but powerful Markdown viewer for the Mac, so I made one.
It supports all the usual Markdown formatting but also diagrams and equations so you can get Claude to not only write up your system docs but also supply a diagram of the database structure, logic, or AWS services.
It would be cool if you gave it a go :-) It is in the Mac app store "ViewMD"
It is a desktop app built with Electron and React. I built to help newlywed couples to quickly sort thousands of wedding photos with a Tinder style swipe UI. It is offline first, fully private, and offers one click export of your selected pictures.
I started building it earlier this year after going through my own wedding photo experience and realizing how overwhelming it can be. I saw my wife dragging and dropping photos from one folder to other and thought there has to be a better way for non-photographer folks.
Right now, I have a working prototype, a landing page live, and I am testing distribution and feedback from early users.
I'm pursuing my vision of "music-i18n": Open source music software that works for microtonal music and worldwide musical cultures.
It's not a from-scratch effort, quite the contrary: I'm trying to tie in existing music standards (MIDI, MusicXML, SMuFL, MEI, etc.) and ensure that FOSS systems (MuseScore, Verovio, smaller components) implement enough of those standards to support music-i18n.
Sometimes, this also includes extending the standards themselves when they are not fully capable of representing some non-mainstream musical aspect. For example, MusicXML lacks the ability of representing multiple accidentals per note (whereas MEI does), which is a must for microtonality.
I started down this path around 2018, as a music player who got interested in arranging Arabic songs in a "Real Book" style. It opened a giant rabbit hole that I'm still far from having fully explored.
Now and then, I collaborate with other devs who are interested in adjacent topics. I would love to hear from some of you here!
Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI.
I am currently working on a new mode that is more like what played walking around: a few rounds in rapid fire, very little time to think before the next round.
Often, when I use generative AI to produce videos, the results are close to what I envision but rarely capture my imagination exactly. Prompting the AI to fix specific details can be a cumbersome and time-consuming process. To address this, I'm developing solutions that make the creative workflow more intuitive. So far, I’ve built an app that allows users to provide visual clues as guides, along with a 3D environment where the camera can be freely manipulated within the generated scene.
The community is moving fast though. Now higgsfield allows using arrows and pointers to edit the video but so far, no one is doing a good camera control visually.
I’m writing a Python framework to create Python home automation scripts driving Zigbee2MQTT with as little boilerplate as possible.
https://pyziggy.github.io
It supports Claude Code and Codex, but has you constantly working on multiple features in Git worktrees. This way you are always able to stay busy while waiting on your agents.
It has built in tools for review, such as a diff viewer, and a quick button to run your application in different worktrees for testing. It has completely transformed the way I work.
Obsetico App (named after a friends' comment that "it's great for Obsessed people like my wife"
A mobile app to track tasks, events and any info about anything you care about: your car, home, tools, workshop, appliances, pets, lab equipment... anything really.
Lets you organize "resources" in a hierarchy (like "folders"). You can then define tasks, add pictures, geolocation, contacts, notes, events, etc to them. Recently added the feature to "share" resources with others.
Still working on https://theretowhere.com, which is a website that makes it easier to find apartments and hotels/airbnbs close to people and activities you care about.
The past couple months have been fun since I've implemented a lot of new highly-requested features into the site's city heatmapping capabilities. One thing I've found motivating is having my own private changelog that shows screenshots of feature requests people have given me, and then dates for when I finally finished those features.
It's easy to forget how much stuff you've built in a month or two, sometimes.
I joined two current interests, my need to learn better JavaScript (since I never used it much) and the discovery of programs like PICO-8. I realize TIC-80 is basically the same but allows me to use other languages, so I’m trying to write small games using JS. I’m still on the struggle phase, trying to learn how to make sound effects, music etc. but I like the fact it comes with everything you need to create whatever you want. Also like how it makes you forget about all the giant software complexity nowadays.
I am working on Octelium https://github.com/octelium/octelium a FOSS unified zero trust secure access platform that is flexible enough to operate as a modern zero-config remote access VPN, a Zero Trust Network Access (ZTNA)/BeyondCorp platform, an API/AI/LLM gateway, an infrastructure for MCP gateways and agentic AI architectures/meshes, a PaaS-like platform, ngrok alternative, and even as a homelab infrastructure. It is basically a unified, generic, Kubernetes-like, zero trust architecture (ZTA) for secure access and deployment, that can operate in many human-to-workload, workload-to-workload, and hybrid environments.
I actually did a SHOW HN exactly 3 months ago and received lots of invaluable critique regarding how dense, overwhelming and unreadable the docs and repo README were. I've actually spent a lot of time trying to improve the quality of the docs and README since then. I'd love to receive any feedback, negative included, regarding the current overall quality of the docs and README from whoever is interest in that space.
Very close to releasing V3 of my Obsidian template vault with huge improvements, first class AI support, included Bases, a solid productivity system, and a ton more.
We are building an operating system for making sustainability compliance trivial. Currently we are using a combination of modern AI agents and traditional methods. If you are a hyperscaler or in a heavy industry or just need support for dealing with e.g. California's SB 253 and SB 261, shoot me a message.
WithAudio a one-time payment, desktop text-to-speech app that helps users read better by highlighting text as it's spoken.
Current Challenges:
Technical: It's difficult to consistently parse text from various document formats. The I also wants to expand to more platforms but I know I need to focus on marketing.
Non-technical: The product has seen some success with minimal marketing, but I keep getting distracted by spending too much time on technical work. I know I need to do more for marketing but I keep going to my safe space (my IDE).
I believe in the product but it keeps reminding me how difficult is to get somethig to a polished, finished state for all users. 90% of the project takes 90% of the time and the other 10% takes another 90% of the time.

I'm working on a video platform called Nickel. 5-second clips and 5-minute (max) videos. I've been slacking on development but realized recently that I lack focus and am easily distracted by other projects. I wrote about this yesterday.
I did figure out something I've long wondered about recently. Y'know how you can see previews of videos in Messages? I got it working! Here's an example video: https://nickel.video/6NI3n_IlIlII
My inspiration for Nickel was 1) missing Vine and 2) not wanting to use YouTube to share my gaming clips.
MAXSTACK: Web framework for rapidly building SaaS apps with AI - trying to enable the next wave of 'fast-fashion saas'. Think of it like better-auth is doing for auth, I want to do for the rest of SaaS
- comes with common SaaS features pre-built (crud, blog, auth, etc.)
- import templates from the framework until you want to customize them
- create forms with just a zod schema
- good docs, typescript interfaces, a CLI for common tasks, and MCP for your AI agent
If you're building something now or want to - I'd love to help. Could use the experience to make things easier through my framework.
In my free time I’m still working on My Financé (I keep getting feedback this name is confusing), which is a fairly undifferentiated personal finance tool.
It’s a labor of love, but I love it!
I’m currently building a simulation engine that lets you forecast your spending, build scenarios (like taking a year off, getting a cat, move to a new city, etc based on your current spending patterns and assets.
I don't know what it is about this name, but I read it as "My Fiancé". My brain did not register the first "n" and it wasn't until I read your parenthetical remark that I went back and re-read.
The name isn't confusing, per se ("get married to/be exclusive with your finances", OK), but it also isn't very strong... "financé" is also very strange and awkward to pronounce as a native English speaker. Probably because it comes across more as Spanish-seeming despite it being a play on a French work.
Since a few months back I am working on a side project to give a snapshot of the regional and global species and natural ecosystems.
I use manual (me) and automated tools (web and literature search tools, llms, visualizers ...) to search, extract, organize and visualize ecosystem literature and data.
If there are some species that are you would like to see a snapshot of, and the region/location let me know and i will try to get a similar visualization.
DM or as reply to the chat.
Share the species name (common or scientific) and location (can be a city, town, region, province, country).
It is a work 8n progress, but I would be very happy to recieve feedback.
I appreciate what you're doing here. I think it's really important to have this kind of high level overview of these species. I have a little feedback based on clicking around the site.
When you click on a country in the map view(under Elephants, for example), I think the map still has focus instead of the card. So this means you can't highlight text, click on links, etc within the card. Also if you scroll using the scroll wheel, you end up zooming in and out on the map.
I wonder if it would be good to have a "see more" link or some such here, so you can view the same information in the card, but on its own discrete page for each country?
Really appreciate that you checked out the website. It is a bit hacky, but for now i am happy with it. Indeed that is correct, the focus is on the map. I am going to fix that. Thank you.
As for the see more, it is in my planning. I can do it manually, but I am waiting for some free time to automated that.
Emilia, a personal relationship manager. Every once in a while I meet extended family (wives of cousins or their children) or I meet a fellow soccer parent and I forget their names, or who's related to who.
I've used Monica HQ to keep track of this but thought I could tackle differently using AI. With AI you could ask questions like "who's everybody on my aunt's side? Like cousins and their family" and get a good answer.
Afaik other "relationship managers" out there are professionally oriented, for sales people. A lot of them talk about LinkedIn integration, for example.
Take a look at http://emilia-workers-website.inerte.workers.dev/ and if you're interested in Alpha testing, send me an email at inerte@gmail.com - I setup a Discord last week so early adopters can chat with me about.
Adding a chat feature to my iOS app size analysis tool that runs locally on your Mac. My goal is to make everyone a build engineer, where you can chat with your builds and get insights and improvement areas. Testing out on-device Apple Intelligence models but need to find the time to do more validation testing.
I'm working on a product to break down information siloes for private market investors. A lot of data for private equity, private credit, and venture capital firms lives in memos, deal books, conversation notes, emails, and chats. In some cases, attempts to organize that data in a more structured format (e.g. using the CRM) has resulted in data not getting recorded because of the friction of managing those types of systems.
So basically, I'm building a system where users can query all of that unstructured data and add more with a little less friction.
Working on Fraim, open-source agents for cloudsec and appsec engineers to complement existing deterministic scanners. Born out of our 3 years of learnings building such scanners for IaC. Turns out in the real world policies are subjective enough to make this hard.
Examples:
- Policies are frequently subjective. Hard to codify, but LLMs can evaluate them more like a security engineer would. "IAM policies should use least privilege." What is "least" enough? "Admin ports shouldn't be exposed to the Internet." What's an admin port?
- Security engineers are stretched thin. LLMs can watch PRs for potentially risky changes that need closer human review. "PR loosens authz/authn." "PR changes network perimeter configuration."
- Traditional check runs (SAST, IaC, etc.) flood PRs with findings. Security doesn't have time to review them all. Devs tends to ignore them. Frequent false positives. LLMs can draw attention to the important ones. "If the findings are unusual for this repo, require the author to acknowledge the risk before merging."
(Will probably register a proper domain name close to release)
Historically, Astro hasn't had an API like renderToString for React/Vue/etc. that takes a component and renders it on the server. That changed with the release of the Container API last year: https://docs.astro.build/en/reference/container-reference/
But there are still a lot of rough edges:
- Importing components is a hassle (you have to go dig through the Astro manifest or create a TS file that exports all your components)
- No Vite integration (so no local dev support, or hot reload)
- No styling support (this is probably the biggest one)
Mighty will provide dev + styling support and a simple way to import your Astro components, with adapters for Hono and Laravel when first releasing. For Hono, it should be as simple as writing a few lines of code:
trying to build a webapp where i apply some recommender systems knowledge to TCG deckbuilding. MtG in particular is suffering from product fatigue and as someone who is both an MLE and a casual MtG player, it has been a fun challenge to apply my skills to a domain of interest
Thinking about vibe coding a Behaviour Change App as opposed to a simple habit tracking app. I have personally used the habit tracking apps, and they are absolutely useless. My app will help the users learn how to actually change their behaviour, teaching them micro skills like value alignment, self-compassion, etc. These micro skills will help them in all aspects of their life and mainly to change bad habits.
I’ve been working on https://fontofweb.com, a search engine for real-world web design.
Most design inspiration sites lean heavily on curated mockups (Dribbble) or award-winning showcases (Awwwards, Mobbin). That makes them polished, but they don’t reflect what most production sites actually look like. Font of Web takes a different approach: it sources directly from live websites, and the community can clip specific elements instead of entire pages. That means you can browse navbars, pricing cards, dashboards, etc., not just full screenshots.
Each clip is enriched with metadata (fonts, color palettes, original domain). Search works across that metadata, natural language queries (“minimalist fintech dashboard”), and even visual similarity — so you can find results either by text or by image.
There’s also a Chrome extension to snip and save from any site.
I’d like to hear from designers and frontend engineers: is this useful in your workflow? Anything obviously missing?
I'm working to build a tool for macOS and Windows desktops to help non-technical users figure out what's wrong with their home internet and how to fix it. https://www.networkweather.com/
It's literally just me in the garage right now banging out prototypes, talking to MSPs, and probing networks/WiFi/OS to make this tool.
The hope is that companies care whether employees are productive when remote/hybrid/on-the-road, or at least are sick of trying to triage first line helpdesk tickets about home network issues and Zoom glitches.
Trying to document my current hobby project, but stuck in the analysis phase. I dont even know what it is. When I try to describe its purpose I get blank looks. People tend to need physical demonstrations to understand whats going on. Its not entirely new, or novel, its definitely not revolutionary, but it is a hybrid of so many things, in a very indirect sense, that its just beyond my verbiage. Not a humble brag, I dont think its amazing or anything. I have just failed to describe it. Have been trying to get a phd I know to look at it, and describe it for me, but he just straight up isnt interested.
Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].
Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.
I hope to sell them and then probably never recoup my investment.
I'm working on a notes app that is as simple as Apple notes, but has native markdown support and uses semantic search.
Uses SwiftUI for the UI, and Zig does most of the heavy lifting on the backend. It's inspired by ghostty which uses a similar setup[1].
Right now it only works for Mac, but I'll be porting to iOS as soon as I get the markdown renderer polished. It's not available to the public yet, but I'm using it as my daily driver and hope to release it later this year. I've open sourced it so you can see the source code here[2].
I'm working a coding agent, named VT Code. It is a Rust-based terminal coding agent with semantic code understanding powered by tree-sitter and ast-grep, and fully configurable and open-source.
A command-line tool called berk that is a versatile job dispatcher written in c. It is meant to replace big clunky tools like Jenkins, Ansible etc. It has syntax similar to git. It works pretty well, just need to iron out some kinks before final release. https://github.com/jezze/berk
Working on the Restful Atmos Sleep Lamp, a smart bedside lamp that automatically shifts throughout the day and night for the circadian rhythm, reducing blue light at night and maximizing blue light during the day. There is a machine learning layer that learns your preferences and automatically adjusts the intensity of the light, similarly to the Nest Thermostat [0].
Also, shipping Bedtime Bulb v2 next month. This is a hybrid LED-incandescent design meant for the evening that is the best of both worlds: low blue light, high color quality, perfect compatibility with dimmers, 10x less flicker than incandescent, includes near infrared, low energy use, long lifespan [1].
I had been unemployed for a year and worked a lot on DiffKeep (https://github.com/DiffKeep/DiffKeep), a cross platform AI generated image management program. Fortunately / unfortunately I got a job and haven't been able to dedicate much time to it lately.
I'm converting PG's essays into latex. It generates 4 "volumes", each with it's own mobile + PDF. It's still early, but am really happy with it so far!
Been exploring the amazing GCAT space dataset - it’s been a good way to drive some dashboard feature experimentation using fun data. Still need to work on my dashboard design skills, though.
A burnout detector for SREs. The goal is to help teams identify incident responders who may be overworked/getting burned out.
We are looking at:
-Objective data: signals from incident management tools (Rootly/PagerDuty), GitHub, and Slack
-Self-reported data: asking the engineers how they feel via short survey
From this, we generate a CBI score (Copenhagen Burnout Inventory). We're still in beta, but we've received positive feedback from our beta testers, especially from manager of large and distributed orgs.
Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation.
The bigger picture: Certificates are often the only tangible outcome of a learning experience. By making them verifiable, permanent, and easy to distribute, organizations save admin time while learners get a trustworthy credential.
Status: Running for 2 years, used by schools and training centers in Latin America. Now building AI-powered features for design editing and data extraction from PDFs.
I had problems sharing my photos on Instagram so I made an alternative:
https://phofee.com/
I made an install script for Arch Linux that sets up the bare essentials for a new install. You can fork it and edit it to your own liking.
https://github.com/QCgeneral29/AIP
I've been building an LLM powered map for the last 6 months. I'm working to reinvent how mapping applications interact with geocoders and routing engines to make much more powerful and easy to use map applications!
I am working on a tiny cli project, tascli: https://github.com/Aperocky/tascli, a local fast and simple personal task and record manager. Specifically, I need to update it to support recurring task and records.
Scrolling Stock Price "LED" Ticker for Windows. I could never find one that did what I wanted so with the help of Copilot I built my own. Still has some bugs I am working on but I would love some feedback!
Banker (banker.so): An AI spreadsheet that excels at spreadsheet understanding (pun intended).
There are some AI spreadsheet products out there mostly as plugins along with MS Copilot. However my experience with them showed that they are bad at understanding spreadsheets.
The reason is that sheets are 2D data models. Because LLMs are trained on 1D data models (simply text), translation of 2D data models to formats an LLM can consume is a big context engineering task.
I read and implemented some of the algos mentioned in SpreadsheetLLM paper released by Microsoft. Ironic, isn't it?
Got it to a nice working state. Give it a go - if you need more tokens, let me know!
- A super easy-to-install monitoring tool that doesn’t require bash scripts or config files
- A mobile-friendly, UX-first interface where I can check everything from my phone
It’s now pretty feature complete. I can see a full picture of all the servers and VPS I run straight from my phone.
Setup is one command, no config files, and everything else happens in the UI. There’s a catalog of predefined alert rules, and creating new ones is easier than anything else I’ve used.
I've been working on LogChef (https://logchef.app) - a specialized log analytics UI for ClickHouse that focuses on powerful querying and exploration without the complexity of full observability platforms.
The core idea is to leverage ClickHouse's incredible columnar performance for log analytics while providing a schema-agnostic interface that works with any log table structure. It supports both simple search syntax for quick queries and full ClickHouse SQL for complex analytics. Also it has proper RBAC: Team-based access controls for multi-tenant environments.
Off late I have also added some AI features:
- AI-powered SQL generation - write queries in natural language
- MCP (Model Context Protocol) server integration for AI assistants to query your logs
It's open source (AGPLv3) and deliberately doesn't handle log collection - instead it integrates with existing tools like Vector, Fluentd, or OpenTelemetry Collector. The roadmap includes REST APIs, client libraries, visualizations, and alerting.
Built with Go + Vue.js + TypeScript. Currently handles millions of log entries daily in production environments at my org. The deployment is just a single binary deployment with a SQLite DB.
I'm working on Matry - it's a tool for designing in the browser. It's kind of like a cross between Webflow, Vim, Storybook, and Cursor. I'm trying to strike a fine balance that I don't see in existing tools.
Nothing to demo yet, but hopefully I'll have something soon.
It gives you precise control over every shade/tint (no AI or auto generation!) so you can incorporate your own brand colors, and helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) against all grade 50 colors, such as red-600 vs gray-50, or green-600 vs gray-50. There's export options for plain CSS, Tailwind, Figma, and Adobe.
I'm really open to feedback on what problems and needs people have for creating accessible designs!
I’m building an ETL tool that “just works” and gets out of the way. I can write shell scripts and python to do this stuff but honestly I just want to drop my files/API results into a GUI tool and have it combine things for me. Landing page is at https://eetle.com
Building https://multi.dev, an AI coding agent with bunch of FOSS contributors
We took a great amount of learning from tools like Cline, Roo.. After spending some time on their tech as active users/devs, we decided to build multi from scratch with drastically different take on core features, tech stack, ux/devex..
If you are an active user of similar tools, and/or want to try multi.. We want to hear from you.
--
edit: I am one of the core contributors to multi. And we are in the process of open sourcing it.
I'm working on a site for filmmakers to help showcase themselves!
Why? >
LinkedIn isn't for creatives.
Actor's Access is dated and charges a ton for basic extras
Squarespace/wix is fine but everyone in 'the biz' has one and nobody wants to maintain it. Plus they're all silo'd.
Check out my site if you wanna. You get to host your own headshots, resume, and reels. You can upload your screenplay there and hear it read outloud. You can put up your cinematic scores and make a place to send people to hear your music.
I'm working on a WordPress PaaS with dedicated lanes for bots. The status quo around WordPress is that you block bots using Cloudflare, else your site crashes. Since AI search is here to stay, we need a way to let bots crawl WordPress sites without crashing the server.
I'm trying to get my agentic software specification tool Arbiter to release (UI polish/debugging is so slow :/, browser shenanigans are harder than Rust fr). It's basically a tool that AI agents can use to construct a project specification. The twist to Arbiter is that the specs are structured and validated, and you can compile them to get:
Services with stubbed endpoints,
UIs with placeholder components,
Dockerfiles/Terraform/K8s infra,
E2E tests (via declared flows),
Github/Gitlab epics/issues/subissues
It's also got github/gitlab webhook integration, so you can do stuff like trigger agents reactively when events occur on a repo, it includes cloudflare tunnel support so you can set up webhooks even in a local dev environment, and the project generator is fully customizable.
Nope, it's a structured spec agents construct using a CLI or MCP (you can also interact with the spec using a web UI). It's CUE, and validated against a schema. Instead of taking your conversation and generating a markdown document that agents might (but often don't) respect, the agent populates the spec in the service from your conversation, then when you're done you can use the CLI to automatically generate a bunch of code.
Codexes Factory: algorithmic tools to create, operate, distribute, and market entire publishing imprints. This week I am launching my first imprint, Xynapse Traces, with 66 books in the Korean pilsa (筆寫) style. Later in October, Nimble Ultra, devoted to the history and practice of intelligence and espionage. Last week I built a giant collection of 575 imprints that are a shadow superset of the ~540 imprints operated by the Big Five publishing houses (Penguin Random House, the largest has ~300). Teeny weeny tip of the iceberg at NimbleBooks.com.
I'm working on a new CAPTCHA designed to be very simple and user-friendly for humans, while maintaining strong LLM bot protection. I'm currently looking for pilot users (content creators, site owners, or anyone interested) to test it out and provide feedback. If you're interested, please comment.
An “everything” feed reader. Its a plugable framework that allows you to push anything into an RSS feed reader type interface. Email, Slack notifications, RSS, etc.
I want one place to manage ALL notification settings. So if I want to be notified of Slack messages that contain the word “cat”, I can do that.
I am also looking to add summarization and tagging using a local SLM. Trying to find a method that can run on older hardware.
I'm building with python/fastapi, react/tailwind/vite, with Claude Code and using test-driven development.
Red-green-refactor is tedious for humans but perfect for AI. And the test names & code make great documentation of every micro decision, running in milliseconds to prevent regressions.
The software itself helps people perform construction approvals.
Old way: dozens of documents and versions sent back and forth over email. Many fiddly details that must be checked - to streamline the process we'll use AI to provide verdicts that help humans make decisions.
I plan to create content & teach what I've learned.
Picshift.io: upload an image, get a URL, change what shows at that URL whenever you want. Works anywhere an image link works.
You can randomize and schedule images to show up at the link as well. Super useful for marketing, maintaining screenshots on a website or in documentation, etc.
I am all-in on a Unity game right now. Working with one other person and hoping to ship to Steam later this year.
Thinking about play testing at scale is a new thing for me. I've been getting into visualization techniques like using 3d textures to build voxel heat maps in-editor. We've managed to accumulate quite a bit of play testing telemetry already. The power of aggregated statistics in the editor views is absolutely mind-blowing to me. For level designers it's like having proper omniscience. Being able to see things like thousands of samples (manifesting as a bright red voxel) that wound up tripping over the same misplaced geometry is like cheating.
i've been incrementally hiking the via francigena (https://www.viefrancigene.org/en/walking/) and am working through integrating my gpx, geotagged photos, and oura ring data to both illustrate my journey and analyze how different terrains and altitudes affected the collected biometrics.
ingesting/parsing gpx layers into duckdb using python to extract tags and load api data. using minio right now but ultimately want to push to cloudflare free tools or vercel.
Building https://pneumatter.com to explore embodying articles of Programmable Architecture (self-assembling buildings)which are weather-compliant, resource generating, and optionally permanent.
Yep, you read it right. 0 false positives. We scan the whole codebase for possible vulnerabilities, rank them, write the proof-of-concept for exploitation, spin up the software in a sandbox, and then attack. All of them happen autonomously without human involvement.
The end report? Only verified vulnerabilities are being reported without noise.
Already reported some unknown vulnerabilities in open source projects. The good thing is we're just getting started.
Improving my 'Video game generator from photos'.
The bottleneck of this kind of generator is 'how much time to obtain the video game".
I managed on my last vacation (it's a side project) to reduced it to 2 hours.
This is an example of one FPS made by my tool :
https://free-visit.net/fr/demo01
I’m working on Colanode, which is built to close the gap between the convenience of cloud tools and the ownership of local software. It brings chat, docs, databases, and files into one open-source, self-hostable workspace where data lives on your devices first and syncs in the background. Unlike typical SaaS tools, Colanode is local-first: everything works instantly and offline, infrastructure stays minimal, and you keep full control of your data.
It focused on critical thinking and communication skills by having dialogues about recent news and announcements at the companies you want to work at. Have a 2 min dialogue and get feedback about how you think and speak.
I'm vibe coding using GitHub Copilot and JetBrains AI Pro on a Blazor web app that tracks my investment in like index funds, stocks, ETFs, etc. It's a simple CRUD web app.
The app is nearly completed, and Grok (preview in Copilot, currently free) wrote most of the CRUD pages with Entity Framework. Of course, it does get things wrong, and I use Claude 4 to fix the issues. (i'm a C# dev, I review code generated by Grok sometimes.)
I created a 2D platformer inspired by the classic Mario games. The game is called Jolly Land Adventure and I made it because I wanted a simple platformer that's easy to just pick up and play.
The game is available on Steam for Windows, Mac and Linux. The demo contains the entire first episode with 30 levels for anyone who wants to try it out.
Everyone’s drowning in long articles, dense PDFs, and hour-long videos. I’m working on https://unrav.io , it lets you flip any article, paper, or YouTube link into the format you actually want (summary, mindmap, podcast, infographic, etc.) in one click.
Right now I’m experimenting with a simple bookmarklet trigger instead of a browser extension. Curious: how do HN folks feel about bookmarklets in 2025, still viable, or do you prefer extensions?
I've been sculpting a static site generator for myself in TypeScript. The focus is on accessible, clean, and semantic output. It's one of those endless projects but it's fun to work on.
I am a bit of a checklist nerd, so I wrote a web app do to checklists: https://checkoff.ai
As it is fashionable these days, it can create checklists with AI ("Fun things to do in Pittsburg"), you can create checklists from templates (some stuff you do every day), etc.
I also have an MCP server that allows you to plug it into your favorite LLM.
Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.
Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.
Building AI workbench and tools for Home Service Business verticals. I found there is a lot of waste in targeting and workflows for business, focussing on improving them with advanced YOLO and LLM models.
It's a personal knowledge system. It's a zettelkasten with an LLM substrate. It uses LLMs to build a model of the theses, arguments and facts used in cards, and uses these to both summarize the information on the card and to automatically link cards together based on shared concepts.
I just shipped 3pio, a drop-in test runner that context-optimizes your test output. It uses your existing test runner and tests so zero changes to your codebase or tooling to use it.
IME it results in much less context clutter from your test output.
Building Bloomberry - an alternative to Builtwith. While the latter focuses on frontend tech, I cover almost every SaaS product category. Want to know companies that use Microsoft Dynamics or Zoom? You can with Bloomberry, but not with Builtwith.
Working on a "Data Governance in a Box" solution for small businesses that are using out of data routers and security practices. Starting here in Canada, but open to collaboration.
I don’t know if this is really necessary, but I created it after doing an in-house CTF challenge, with no LLM rules, and I was giving several LLM CLI’s a lot of leeway and iterating very quickly.
I'm working on a super-simple budgeting app called https://4keynumbers.com, which is based on Ramit Sethi's Conscious Spending Plan. It currently syncs my expenses from Plaid and cooks it down into a single chart, with only savings, investments, bills/fixed, and "safe to spend" as categories.
I am creating a webapp to let screenwriters collaborate when writing their scripts.
I have several friends in this industry and their tooling is either expensive, not localized for their market or straight away bad (I've seen terrible dataloss).
I got some inspiration from linear and am building it on top of ruby on rails with CRDTs.
Scriptwriting require specific formatting (set by Hollywood ages ago). Doing this in google docs is really painful. Besides that, people who work in this industry are already used to the format, so if you wanna pitch something to studios, they expect to be in industry format.
This is mostly a nostalgia play--I'm pining for a time when app development was much easier. I'm trying to apply lessons from early Rapid Application Development while still providing a full-featured language.
I confess that I haven't gotten any traction at all, but I find it incredibly useful for my own consulting business, so I'm going to keep on working on it.
I’m at a crossroads with my Speed Cubing Competitions listing app (SCComps.com). It’s an iOS app built in Flutter, has around 250 downloads, and currently generates no revenue. I'm spending about $500 a year just to keep it running. There’s little community engagement, and I'm debating whether to double down and rebuild it in Swift—or just shut it down altogether.
pptx-tools, a collection of cli tools for interacting with Powerpoint presentations. Covers use cases that PowerPoint doesn't support. Currently in the making:
* pptx-grep - find text across multiple powerpoints, yield file/slide no and text excerpt of match
* pptx-dump - dumps extended info about a powerpoint, such as number of slides, applied master slides, used fonts etc.
* pptx-lint - allows to define validation rules for pptx based on content and/or formatting. E.g. presentation must not contain word "TBD", all text must be formatted in Arial etc.
Trying to build a secure, configurable and easy to use authentication system (relative to my understanding)
I have experienced knowledge gaps and blind spots that I am attempting to fix. For example most users worry about security of hashed passwords and yet they do not realize that the TOTP (eg Google Authenticator) use symmetric encryption and quite a lot of the authentication providers store the private key in plain text in their database. List goes on...
I’m working on yet another cloud based coding agent https://seniordev.io/ that connects to an existing GitHub repo, spins up a feature branch, commits incremental changes, and opens a PR. You can jump into an embedded VS Code server to review and tweak the code before merging—no local setup needed. Any feedback is greatly appreciated Thanks!
Currently I've been working on https://terragonlabs.com which is a way to orchestrate Claude Code and other agents (Amp, Codex) as background agents.
I feel like I am locally constantly bouncing between different agents for different tasks and really wanted to be able to do the same in a remote environment.
A script which will find random pictures of anyone in the family from the Immich database, resize them and add metadata on them like where they were taken and when and put them on the TV to show as kind of a screen saver when we're at home.
I like this Facebook feature which shows you "Today 10 years ago", Immich, does have it in it's UI too and perhaps I will mix in those pictures also to show on TV.
I'm working on a text-based softball league simulator where you forcibly enlist your friends and family to join your co-ed softball team. You play as their manager/coach/fellow player.
Every aspect of the games are narrated in real time so you know what's going on. I'm still in the prototype stage and I've seen some pretty hilarious interactions already.
Currently working on a prediction market platform. Although big players like kalshi are pushing this narrative very hard right now i think there is space for a more social focused platform where users can play together.
rovr, a terminal file explorer because there just isnt enough competing
using the textual framework, i have proper mouse handling thanks to it, that i noticed was missing in superfile, or just wasnt nice to use in yazi
im taking a look at asyncio to replace threads in the program to hopefully help performance
https://github.com/NSPC911/rovr
Deterministic guarantees, and corrective behavioral monitoring for ai agents (starting with claude code, and ADK). Think security + performance bumper rails. At the cost of 0 context.
I was the feature requestor for Claude Code Hooks - and have been involved in ai governance for quite awhile, this is an idea I'm excited about.
Ping below if you want to early beta test. everything is open source, no signups.
I've been working on writing two appendix sections on knowledge distillation and reinforcement learning for Machine Learning for Drug Discovery [1], which were initiated as tangents to expand coverage of material from a few earlier chapters. I hope to also write these appendix sections up as freely available articles (at least in a condensed form). Thankfully, I'll be able to finish the knowledge distillation section this month but, unfortunately, I need to pivot to finishing out chapter 11 to stay on schedule for full publication.
Im working on (slowly) a very very niche web app to help my wife manage her dog breeding program. Maybe it'll be useful enough for other breeders to use it.

I'm working on character.ai for learning Chinese, you chat with characters at your level, and get instant feedback on your writing. It's a way to get a wide amount of comprehensible input in an engaging way that also practices output.
This is really cool, I'm interested in this as I'm also a chinese learner and I thought about doing sometihng kinda similar (just locally)
I like the UI, really cool project.
I think the prompting might need more work to make it natural though. I just tried a "hungover chat with 996" worker, and the responses seemed to be lacking a little too much context
Writing a specification for a personal library app in the hopes I can get AppSheet + Gemini to make one for me. I'm working on library science in general, so it will hopefully implement ideas I have about book classification and entity catalogs.
Working on an AI-optimized query language. Like a terse, logical SQL. So smaller models can translate natural languages to DB queries more accurately. Saves lots of compute in RAG.
I got a dumb phone. Been messing around with setting a phone number to call to get SMS directions and things of that sort.
Then I wanted to build my own phone so I got a LTE module and been messing around with that.
About the first part, I am working on something similar for myself. If you want an api to get SMS for free, without needing any 10dlc stuff, check out groupme, which supports SMS.
I’ve created an AI-powered app designed to help candidates prepare for Meta’s product manager interviews, with a focus on product execution questions. The app allows you to practice by speaking or typing your responses, then uses AI to score answers against a rubric and track your progress over time.
I’m looking for beta testers—happy to share early access if you’re interested! If you are please message me.

I've been considering open-sourcing it due to lack of commercial success, but might try an ad-based approach first.
creating a kanban editor for vscode that can integrate images, videos etc. i use it for planning and creating lectures over several weeks. it can export to a marp compatible presentation format. it's coded with claude, because i would not have had the time to do it othervise.
For me, I'll probably send an email later to support to ask (no rush, since it's out of stock anyway), but I was checking for info on compatibility with Yamaha (e.g. my Cross Connect) ebikes. It's not on the compatibility list. They make their own (mid-drive) motors (PW-SE on mine I think) and proprietary batteries. They pulled out of the United States market altogether so getting more batteries from them again is doubtful. (Mine currently charges to ~85% and then throws an error code, but it still works for now.) It is a Yamaha 500Wh36V battery pack on the down tube with 3 wires (I just unscrewed where the battery plugs in to see).
I suppose it has moved from “what are you working” to “what have you worked on” territory, but since I wrapped up the website just about a week ago it still feels quite fresh.
Always interested in feedback and what folks find useful! It’s focused on the mechanics of writing understandable software, which I think is especially important in the age of AI slop.
An extension which treats tabs as a stack - so I can go down a rabbit hole opening new tabs and then use a shortcut to close a tab and take me to the parent of that tab
I've see so many HN posts and cmments about CSVs sucking and Unicode control characters as delimiters, that I set about creating a spec and some tools for use with it.
Nothing good enough to share as its own post, but its something I'm working on that people may be interested in.
Traditional Knowledge: Constrained to Ibn Seerin's classical teachings — trusted by Muslims for over 1,000 years
AI-Powered Analysis: Unlock the meaning of your dream with 4,300 dream symbols from the Dictionary of Dreams.
Share your dream confidentially, answer a few context questions, and receive your authentic Islamic interpretation in under a minute.
This is an MVP which I started <4 weeks ago. Currently validating Desirability, Feasibility, and Viability.
Confidentiality is very difficult to guarantee. You may want to put some brackets on what your users can realistically expect and give them tips on how they can stay anonymous. But lovely and novel idea, really neat to see these kind of cross-overs.
On the app's dream input page, it specifies a bit more "Your dreams are private and not stored or collected." - would that cover it? Thanks for your feedback and encouragement!
That is a 'pinky promise', it may well be true and let's assume you are well intentioned but it leaves the door open to you not being trustworthy after all or someone intercepting the data while it is being processed (for instance, by compromising your service).
In order for you to process the dream data you have to at least make a temporary copy. One way to get rid of that is to move the interpretation part to the client side if possible. Another thing you could do is if people are really concerned about the content of a particular dream to suggest they use TOR or some other anonymization (not perfect, I know) service to at least hide their internet location from you, the operator of the service.
Does the app itself run entirely within your own infrastructure or does it call out for part of the work?
Kind of have been wasting time with Cloudflare workers engine. Trying to build a system that schedules these workers for a lightweight alternative to GitHub actions. If you are interested in WASM feel free to reach out. Looking to connect with other developers working on the WASM space.
Oh hey I can post an update. My little electronic dictionary is finished. Software works and it's all dressed up in a stealth notebook case. (It runs Python now instead of Lisp though)
I've been wondering for years if historical magazines/periodicals could ever be transformed into a modern ebook format. PDF doesn't cut it, but most other efforts are unsatisfactory... part of what makes a magazine a magazine is the rich, mixed content. So, for the past few weeks (months?) I've been taking a stab at it with the science fiction pulps. Started with Analog/Astounding, and I was able to re-typeset the cover (with original art), most of the interior, many of the ads, and so on.
For now, I think it would be funny if you put plaintext that says "just bought the milliondollargpt.com and have no idea what to do with it...". Optionally as a hyperlink to your comment I am replying to.
I'm writing a programming language for feature-flags/remote-config. I figure a simple DSL has to be an improvement over YAML or a series of forms in a web app.
I'm also generally disappointed by the lack of testing that's performed on feature-flag definitions. So I'd like to have a test runner capable of asserting your feature flag's rules matches your intent.
I have been prototyping a local-only social media manager initially targeting the game development community. I am sick of all the subscription only platforms such as buffer, hootsuite etc.
Initially I have been looking at Mastodon and Bluesky since they have sane APIs.
The plan is to make it so that you can sync your data folder either manually (e.g. dropbox, or sneakernet if you want) or a via a basic cheap data plan.
I've been building an innovative guided munition for Ukraine for the last 4 months, we have first prototypes made and have arrangements with the testing range to begin flying them soon.

My theory of learning is that you learn the characters better if you learn how to read and write them at the same time. And flash cards are better by giving you as much information as possible about the character.
This is fundamentally different from e.g. WaniKani which only teaches you how to read the character and relies on pre-made mnemonics (plus SRS) for easier retention, and from Anki which (normally) has very minimal flash cards, showing only small bits of information per card. When you have the whole dictionary on each card it gives you the opportunity to create the easiest connection with what you already know. This may be some made up story about the components (radicals) in the kanji (like WaniKani does) a word you already know, other kanji sharing the components, etc. The more connections you make the easier it is to learn them.
One of the features I personally use extensively is the ability to bookmark words containing the kanji, which will then pop up at the top of the words section in a later review. If I remember the meaning and the reading of the words I have bookmarked for this character during a reading review, I consider mark card as good. If I remember none of them I mark it “again”.

For the past ten months I've been working on a way to transmit and receive around 10 kilobytes halfway across town. I've blown through government grants totaling in the hundreds of millions of dollars but it seems this is an unsolvable problem.

Currently a one-man side project:
https://laboratory.love
Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.
This seemed like a solvable problem.
Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.
Here's how it works: Find a product (or suggest one), contribute to its testing fund, get detailed lab results when testing completes. If a product doesn't reach its funding goal within 365 days, automatic refund. All results are published openly. Laboratory.love uses the same methodology as PlasticList.org, which found plastic chemicals in everything from prenatal vitamins to ice cream. But instead of researchers choosing what to test, you do.
The bigger picture: Companies respond to market pressure. Transparency creates that pressure. When consumers have data, supply chains get cleaner.
Technical details: Laboratory.love works with ISO 17025-accredited labs, test three samples from different production lots, detect chemicals down to parts per billion. The testing protocol is public.
So far a couple dozen products have received some funding, six products have been fully funded (five product results published, the sixth is at the lab as I write this!)
You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love
Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.
Second this, it would be useful to have a "EU safe" label or similar to help me understand if 635.8 DEHP is a good thing or bad.
Thanks for the feedback. Yes, data readability is on the roadmap!
Or "NON-GMO" label would very extremely helpful too.
Thanks for the feedback. Yes, data readability is on the roadmap!
Your blog doesn't seem to expose an RSS feed - I'd like to follow your progress.
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.
Consumer Lab does this testing. It's great, you just have to pay for a membership.
Thank you - had no idea.
Wow... AI told me that all the tested products far exceed the EU limits!
I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.
This is great. I thought about a different model even before plasticlist: make a subscription and test various products, but people will have a number of upvotes based on their sub streak. They vote for food to test, and then you show results to everyone subbed. Kind of like what examined does, but they do deep dives into medical topics for subs. I think this model will work better than the one you currently have. Awesome project anyways!
It is extremely weird to me that countries don't do that on taxpayers money and show the results publicly, this is what they should do.
I definitely considered a voting mechanism, but there are a few million active, buyable CPG UPCs in the U.S. at any given time. When conducting some basic market research for this project, I found that most people are only willing to pay to find results about the specific products they care about.
What would be a good strategy to prevent companies from cottoning on to this and gaming the system? They could for example change packaging on production runs for a product that’s undergoing laboratory.love funding campaign.
It's an interesting thought. Companies do change packaging somewhat regularly. However, the underlying skew usually remains the same. Changing the packaging and/or the SKU is very expensive. It's probably cheaper and more beneficial to your company to do your own Plastic Chemical testing and get ahead of the problem.
My suspicion is if this was gameable, this would be a solved problem by a number of companies. The truth is there is no single simple or even hard step to take, it’s mostly like numerous steps that multiple actors would need to do.
A couple of suggestions:
The completed entry should include the date of the test results, so currency can be judged,
Ideally the completed entry should contain a scan of the full test report from each of the accredited laboratories.
Both good ideas and on the roadmap!
Can you talk a bit about the tech stack?
React + Vite + Tailwind on the frontend; Netlify Functions for backend with Stripe, Supabase, and email integrations; content via Markdown build script; deployed on Netlify; linted with ESLint; JavaScript-only codebase
LLMs wrote 99% of the code.
The product label images loading on the homepage are huge right now. They are displayed in 128px * 128px box but are about 2 MB in size each. May be generate resized versions at build time and use <picture> tags?
This is so incredibly important, well done. The problem of our food being steeped in plastic hits the news here and there, but it should be front and center in my opinion. Testosterone has been plummeting for decades and it scares the heck out of me. The hormone whose job is "form goals, shrug off failure, and try again!" is being destroyed and corporations are given a free pass to pump us full of phthalates and bisphenol. It's infuriating.
Plastics could be part of it, but three years ago Cleveland Clinic said it could also be weight, sedentary lifestyle, poor sleep, diet, and alcohol
https://health.clevelandclinic.org/declining-testosterone-le...
And anecdotally, I've still been forming goals and shrugging off failure five years into suppressing most of my endogenous testosterone with exogenous estrogen
Have you had your levels checked?
Well that's great for you, but I was making a generalized statement about the role of testosterone, scientific data showing huge decline, and more and more studies linking it to plastics. We can't just alter a key hormone within the span of a few decades and shrug it off. My levels are great for a 40 year old
And yes there are certainly other factors, but that's not what the original comment was talking about?
Theres a cheaper and more pragmatic solution to this. Just inject T lol.
Cool project!
I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet).
It uses 4k stereoscopic capture and bunch of ML models to match bone position with sub-millimeter precision. The surgeon screws a metal base piece into the bone, and we detect where that is in space. Then, a Stewart Platform adjusts another part that is placed onto the base. The robotic adjustment allows the base to be placed in a ballpark area, with the robotically-adjusted piece oriented in the exact spot where the surgeon needs to cut.
The net result is a robotic system that is many times cheaper than the least expensive incumbent, decreases surgery time significantly, reduces error, and basically "just works" as opposed to requiring a ton of training. We are debuting at a tradeshow in October.
This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing
I'm working on Small Transfers (https://smalltransfers.com/), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers.
You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets.
If combined with subscriptions, the pricing can work similarly to mobile plans, where monthly plans become cheaper above a certain usage threshold.
Looking for more developers to try it and share feedback.

"Google maps but for old maps": https://pastmaps.com
This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .
It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.
Nice project! The National Library of Scotland has a nifty tool focused mainly on the UK and Ireland that does something similar (with a paid print service attached): https://maps.nls.uk/geo/find/marker/
I would absolutely love if you brought Canadian maps to this.
I work for Build Canada and I would love to see some maps from the fur trade and early exploration to tell stories.
If you want to chat my email is brendan at buildcanada.com
Hey, cool to see!
I'm running a similar but smaller project (5k MAU), my oldest map is central London in 1561
https://onamap.me/maps/London1561/
I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps.
My home page is here for more: https://onamap.me/
I also came across this similar project a while ago:
https://www.verbeeld.be/2024/11/17/using-gps-in-the-year-156...
Good luck continuing to build out the project!
That's nice! I have some GIS data of my country it was pretty detailed, it may be outdated now, but covered a good amount of administrative details. If you are extending and need some data on Bangladesh, I can send you
I've always wanted a map with a horizontal slider for the year, so I can watch the map change as you slide further back in time.
I know that's different than what you're building, but what you're doing is super cool. Nice work!
GIS is underrated. This is awesome!
Have you looked into speaking with the various SHPOs in each US State/Territory?
I've worked with several of them a fair bit and they have a ton of old maps hidden internally. Especially for small, specific areas of the state, like historical districts.
I would love to use this if it supported Italy
Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.

I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups.
Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those services provided all the information on a book. One might provide the series, the other might provide genres, and yet another might provide a cover with good dimensions, but none provided everything, so I decided to work on something of my own (called Librario).
While Shelvica is the focus, Librario could become its own thing in time, so I don’t mind the sidetracking.
I also plan on having a “ISBN Search” kind of website that feeds from that database as a way to let users search for information about books, which then feeds the service’s database, making it stronger for Shelvica.
I open source everything I make, but I’m still wondering if these will be open sourced or not. I’ll probably go with the EUPL 1.2 license if I do decide on open sourcing them.
[1]: My wife and I have a personal library with around 1800 books, but most applications for management are either focused on ebooks or choke with this many books. Libib is the exception, but I wanted a little more.
I'd love to get updates on this and talk with you. My email is ben@bookdna.com
We are in the process of building Notion but for books (specifically aimed at your to-be-read list and book log): https://building.shepherd.com/roadmap/launch-our-tbr-app-to-...
Very interested to hear how it goes.
Interesting! Have you looked into data from Anna (https://annas-archive.li/blog/all-isbns-winners.html)?
Didn’t have the time yet, but it’s on my todo list. I have extractors for Google Books, Hardcover.app, and ISBNDB already working, and Amazon, Goodreads, and Anna’s Archive in the todo list.
I do plan on including a link to the book on Anna’s Archive in the “ISBN Search” website. At least to the search page with the filters already filled.
Hey I'd like to learn more about what you're doing. I'm working on a tangentially related service but focusing on audiobooks. One big stumbling block I ran into early on was trying to find something close to a unified ISBN datasource.
If you're up for it, shoot me an email at charles@geuis.com.
I need the search service so bad.
I attempted something like this because I wanted a good books search service which provided me at-a-glance information I needed from Storygraph & Goodreads. The main things I look for when I search a book is genres/Storygraph's "moods", number of pages, whether it's part of a series, rating across services & how much does it cost.
Could never make it work properly.
this month, i've been building https://tierbudddy.com and https://passportphotos.co
I finally collected the courage to release my operating system into the wild:
https://news.ycombinator.com/item?id=45400006
I'm super curious if anybody will pick it up and do something useful with it. This was a couple of years of my life and I absolutely loved working on it but having a child put a hard stop to such entertainment for many years. Now, a good 30 years later I finally found the time to resurrect it.
I'm not sure yet if I am going to do more work on it or leave it as it is, it's good enough to give someone new to OS development a running start and a foundation to build on.

In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.
Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).
Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!
That's such a great idea. Especially since you're also helping the restaurants out. Nowhere near that area otherwise I would've petitioned straight away
This is an amazing idea tapping unto the one thing we most humans love which is food. Kudos!
Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/
Recently, I have released a simple IDE (called the Bench) to try Circuitscript online: https://bench.circuitscript.net/
The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circuitscript tool (currently only the desktop cli tool) is able to generate KiCAD netlists and this can be imported into PCBnew.
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
As a big openscad fan I love the idea of designing circuits with code.
I do wonder though about designing circuits vs designing schematics. I see you have ‘wire down 100’ making it a more visual language than defining the nets. Be interesting to separate the schematic layout from the nets, so rule base schematic layout can then be applied.
I love this idea! Just wanted to send a note of encouragement. Keep at it!
Thank you very much!
Hey I am a embedded sw / hw engineer. looks pretty neat. would love to talk to you about it
Sure, let's talk! Please contact me at my email in my profile. Thanks!
I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy.
https://github.com/scallyw4g/bonsai
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
https://github.com/scallyw4g/poof
That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a small forest).
Great to see something along those lines but with much better visuals.
That's an interesting application! I'm excited to see where these kinds of projects go now that we have so much computing power.
This thing I built was in 2006 or so iirc, here is a screenshot:
https://jacquesmattheij.com/snapshot4.png
Apologies for the low resolution, I don't think I have a better one.
Wow the voxel engine work is beautiful! Impressive work man
Thank you! It's definitely been a labour of love
Cool. Especially love the low dependency approach. Readme says OpenGL 3.3. Are you doing the GPU compute using old-school GPGPU techniques?
Working on a dutch voting compass that uses real world motion votings as a way to determine which party fits you best. The Netherlands got an open API for this since last year, so it felt appropriate to start using it.

I launched Quiet UI this week:
https://quietui.org/
It prioritizes accessibility, longevity, performance, and simplicity.
With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)
Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.
All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).
Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.
Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator
The library is free for personal, educational, non-profit use. Commercial use requires a license.
Your docs are great! How did you create them? Did you use external tools to generate them?
Awesome components library. Well done! I might definitely try it in one of my next projects.
Nice. Great work. Bookmarked
Great work!, love the simple aesthetic
FYI the browse components button clips text from the next section on ios
From the text ‘What's in the box?’ Only the W is visible
Thanks! I’ll look into this.
I'm working on top down shooter for the browser (co-op to come) https://www.demoncleaners.com/

Trying to build browser games that feel more like Steam games.
Impressive! Feels really responsive. I feel the controls are a little unusual though: WASD corresponds to actual map orientation rather than to where the character is facing. I find it confusing when playing together with a mouse, where I would expect I can hold W to move forward while using the mouse to control the character's orientation and direction.
The initial implementation actually used that approach - but I got some complaints from people saying it felt weird and I changed it. That was a long time ago during prototyping though - might change it back and see how it feels now (or just add an option). Thanks for the feedback.
I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).
My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.
Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.
The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.
It's easier to show than tell. Take a look: https://typegres.com/play
Very cool!
I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.
My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.
Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk
I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.

Thank you, can not reproduce yet but will investigate.
Working fine using Windows 10, Firefox 143.0.1 (32-bit), old desktop for web facing browsing etc.
TBH I would have thought it would have been a 64-bit version, regardless, it's not a universal FF issue, more a your-setup specific hiccup.
Building SupaBird.io - reverse-engineering viral X content so you don't have to guess what works.
Here's the catch: most creators study top accounts but can't replicate their success. They miss the patterns.
Analyzed 1M+ tweets from top performers and built AI that doesn't just copy - it adapts their winning frameworks to your voice and niche.

A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use.
There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.

I'm currently building Visirya, an app that helps people record their night dreams and transforms them into short videos and written journals. The bigger goal is to use this dream data to create dream cartographies, essentially maps of recurring themes, emotions, and symbols—to uncover patterns and insights across dreams over time.
So far, we've built the video generation and dream journaling features. The app is live on TestFlight, and we're preparing a major update soon that includes a new better UI, and dream questionnaire to help with pattern recognition and dream mapping.
Would love to hear thoughts, feedback, or connect with others working on similar intersections of tech and the mind! If you're interested in trying it out, you can find the TestFlight link on our website: https://visirya.com
The idea is nice, but I wonder if a generated video can have any resemblance of the actual dream. At least for me, dreams are very tied to emotion, and the visuals are kinda blurry, so i don’t know if that sort of thing can provide any satisfaction. But I know certain aesthetics can feel “dreamlike”.
Super cool! I'm building in the same space but for Muslims - Dreamstate: Interpret your dreams Islamically https://dreamstateai.replit.app/
I tried your app - it's quite abrupt to go straight to Access Microphone permissions. The voice recording took a long time to analyse, it timed out for me. It's a great idea but didn't work for me unfortunately.
On the side, custom coloring books for kids using nano banana, started with a project for my son, and its a little janky for some photos but have had some interest already: https://bespokebooks.io. I think it needs to be a phone app to really work for most people though, so that's next on my to do list besides some prompt tweaking.
Notebook to do it yourself here: https://github.com/dbish/bespoke-books-ai-example
I think there are a lot of really fun projects possible now in the child book creation space, particularly as you build tools that they can use themselves (like adding voice interfaces to building a book or story).
This is outside my 996 job of AI Agent/Assistant infra + ops :)
I've had similar ideas involving bespoke print on-demand books, could you share how you actually get these printed/published?
Working on a webapp for critically think with others about a problem.
The idea is that you build a diagram that contains all the details about the problem and people's thoughts on it, and it's organized in such a way that it's easy to just keep refining, down to the smallest detail. So you build this concrete, shared understanding, and move it forward and forward, until hopefully y'all can make some best decision to improve the situation.
There's a lot to do. Currently working on UX to allow hiding intermediate nodes and still have indirect edges drawn. Want to add an LLM integration to generate/update diagrams via natural language, which I think will help a lot with usage barriers to using the app.
Happy to get any feedback :) https://ameliorate.app/ https://github.com/amelioro/ameliorate
I wanted something similar for a worldview. I want an app where I can dump all the things that actively go into shaping my worldview and then when someone wants to know why I think the way I do, I will share them the link of my worldview board. We are not famous people to have our memoir written but this is another way to peek into minds of strangers.
That's a cool idea. Seems like there would be a ton of things contained in an individual's worldview, that it'd be hard to build all of it up. Perhaps when you encounter something that makes you think of some core philosophy, you note it and the philosophy, and eventually there would be a loose picture that forms amongst all the relations.
Certainly would be helpful for trying to understand someone else. Not sure if this is totally appropriate, but it does seem like something that a chatbot would be good at combing through to find examples to suggest why one thinks a certain way about a new topic. You could even ask it about your own worldview!
Currently working on: https://postply.com
Postply uses full-context to generate better replies on X, Instagram, Facebook & LinkedIn. It supports custom reply profiles and styles for support teams and social media managers. There are clearly a lot of AI replies on social media already, but they are really generic and bad. With Postply.com I'm hoping it will help people generate better and more meaningful replies.
Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.
I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.
The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.
I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.
Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.
Reminds me of John Petrucci's Rock Discipline instructional video where he outlines exactly this technique on how to build up speed.
Great instructional video. First place I learned E natural minor with his scale fragments section.
Yes, not a new technique by any stretch of the means. AFAIK John Petrucci takes a less aggressive approach with raising BPM. Funnily, Shawn Lane goes into a very similar methodology >30 years ago[1].
[1]: https://youtu.be/dpLDN1QCkQM?t=112
When will it be done? Would like to try.
At least a couple more weeks. Hopefully less than a month out from now.
I have most of the UI done for sequencing. Workflows for speed building and metronome sequencing will be completely free, which is also a top priority for me to get out the door first.
I got tired of Spotify recommending me the same songs, from the same artists, over and over again.
So I built Riff Radar - it creates playlists from your followed artists' complete discography, and allows you to tailor them in multiple ways. Those playlists are my top listened to. I know, because you can also see your listening statistics (at the mercy of Spotify's API).
The playlists also get updated daily. Think of it as a better version of the daily mixes Spotify creates.

I still am not sure exactly how to define it, but it's a ruby library, that is mix of a rules engine+spreadsheet feelings+array language+static validation+compiled/codegen... that last part is mostly not merged yet but yeah, ruby DSL codegenerating ruby, it's ruby all the way.

Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here's a tarball containing everything" to "here's 500 packages", with resulting changes in the build process, download/update mirrors, installer, etc.)
What's the ETA?
Target is 2025-12-02 00:00 UTC.
Given that this is a major release, there are fairly wide error bars on that; it could be as much as 3 weeks earlier if the first release candidate turns out to be perfect, and of course it could be later if things go badly (but I very much hope to get it out by the end of 2025).
That's a massive job. Much good luck, and a lack of gremlins!
Definitely a massive job. Some FreeBSD developers have stepped up to volunteer tremendous amounts of help (and also the FreeBSD Foundation has paid staff helping out with parts of this) but my best guess is that I'll be spending around 300 unpaid hours making this release happen; I've been doing pretty much full time hours on this in September and I'm really hoping that once pkgbase moves from "need to implement the stuff which isn't implemented yet" to "need to iron out some bugs" I'll have time for other things... like my paid job, Tarsnap.
Very much a hobby, but I'm working on a Pinterest alternative built on ATProto called Scrapboard[1]
The Bluesky ecosystem is a really great platform to build social media on and with Pinterest being overtaken by AI content I figured I'd give it a shot. There is definitely not as much content there, but it is of much higher quality and the culture of providing alt text on images really makes search work rather well.

I'm working on ScaleDown [1], a context pruning API.
So over the past few years, I have seen how contexts have been steadily growing in AI apps. And while the context lengths of LLMs have also been increasing, they are still effectively about 200k tokens. The performance drops off a cliff after that (you might have noticed it as well with long AI chats).
It is a simple API that prunes away irrelevant parts of a context for a given prompt, a.k.a. context-aware pruning. Integration is super simple: just an extra API call before the final LLM API call. You can get an API from the website.
I would love to chat if this is something that is relevant to you and if you have any feedback on what we are building!

I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long.
For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that.
I think people feel that this is a poor match for how money works. So they improvise. And because we tend to not discuss money with others, they improvise on their own. What this typically looks like is checking their balance and trying to pace things.
I’ve been trying to design the app around that. Providing support to what seems like a natural, instinctive approach to managing money.

I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this?
And which cards / banks does it support?
Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.
I've been working non-stop on my game development tutorial website:
https://raizensoft.com/tutorials/
Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion.
Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it's quite underserved at the moment.
In the future I may expand to other code-centric frameworks and more general game development topics, let's see how it go.
First time hearing about libGDX. Do you have any resources on why it's your favorite framework? It might be useful for your website as well. To sort of "sell" the framework to game developers who have not used it before.
libGDX is not in the same spotlight as Godot or Unity but still popular within Java devs circle.
I'm not aware of any resources explaining the "why libGDX" but here are some differences, speaking from my own experiences:
- Code oriented development, no authoring tool, no drag and drop, just you and the API, which might attracts traditional devs who prefer a pure coding approach.
- Very thin abstraction over the platform graphics layer, it just adds a few more drawing APIs over the underlying graphics API (OpenGL and WebGL). You’re free to build your own abstractions on top of the core APIs.
- Java, while might be verbose, is very stable, easy to learn and has huge ecosystem. Or you can just use Kotlin.
- Once you learn the ins and outs of the framework, it actually has a greater sense of freedom compared to Unity, Godot, Unreal, etc because those engine always force you to do things in their own opinionated ways.
Great, I will check it out, I am a Java dev and always wanted to learn about game programming!
Learning Ruby on Rails through building simple web apps for myself.

I’ve been working more on the unit economics of my data union/trust idea (https://wherelabs.info/).
What I’m trying to understand is whether it is viable to pay people ~$5 per week for sharing their location data and demographics based on a 90% share of revenue from sales of data products built on that data. (But without ever selling or exposing individual level data).

Best of luck. I've known so many people in my circle deal with infertility and miscarriages. Hope you succeed.
You might just beat the Mombasa Hatchery and Conditioning Center's record!
Do the same for chicken eggs
Are you making a joke, or is there some use for that? (I would think of all species on earth, chickens are the easiest to get eggs for once you exclude the insects, but lack of domain knowledge means I could easily be missing something)
Not OP but I think there are a lot of people (maybe mostly vegans) who would be interested. I have no thought on whether it would be financially viable.
I'd be interested just because I'd rather use non-animal alternatives if available.
I hope lab-made milk becomes a viable thing even though I'm not vegan or vegetarian. Lab-made eggs would be good too.
As someone who's dealt with this and know more people, good luck.
You're doing God's work, pun intended.
I'm working on an audiobook service (currently for myself) that will fill in major missing features for platforms like Audible.
- Ignore AI voiced books
- Show me unread books in series that I have in my library
- Experimenting with better search. I have experience with building semantic search systems and have been highly disappointed with Audible's extremely sub-par search capabilities. I want results that are actually based on books, authors, and narrators that I have already purchased, read, or listened to.
- Get automatic notifications when new books from authors and narrators that I subscribe to become available.
There's at least a few more gripes I want to address, but these are the high priority ones that come to mind right now.
>- Ignore AI voiced books
My biggest issue these days, is that after spending 1000 hours messing around in eleven labs, almost all female american audiobook narrators sound AI generated to me. I feel like as a demographic they must have sold a lot of voice recordings to the platform for analysis. I have DNR'ed a few audiobooks recently due to this.
I've been making and selling my electronic social battery pin badges for a while now (https://hortus.dev/products/social-battery) and I'm expanding the range with seasonal versions like a Christmas mood badge, and a halloween themed ghost badge that's coming soon. I'm lucky enough that these projects have gone down well and are making enough money to fund some more complicated (and expensive) projects that I wouldn't have otherwise had the guts to try. Currently I'm working on an RGB digital sand timer with customizable timing sequences so that you can use it for things like the pomodoro technique - I have a working prototype and at the moment I'm experimenting with interfaces for setting the sequences. I wanted to use a combination of buttons and an accelerometer for this but it's not as intuitive as I'd like so I may end up making a small smartphone app to configure it.
Building https://fallinorg.com/, a Mac app that organizes your files.
It looks inside each file to see what it’s about, then moves it to the right folder for you.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It already works with PDFs, text, Markdown, and many other file types. Next I’m adding ePub, and later Microsoft Office and iWork support.
If you have messy folders anywhere on your Mac, Fallinorg can help.
I pride myself on being pretty well organized with my digital life, especially files and folders. I’ve been using Hazel (God Knows, since it's beta). Recently, I realized it has become a muscle memory for me to name/rename files, and drop them where they belong while I'm working on or as it happens. This works for me now because I have a weekly routine of digital chores that picks up any slack and missing things that I missed during my days. Compound this with the fact that I have reduced a lot of clutter, minimized things that I’m involved in. That worked. I did away with Hazel since the beginning of 2025 and I didn’t missed it.
However, I’ve been sheepishly and shamefully looking at either an AI-assisted solution to even do away with the last mile cleanups and organization that I do.
Your text above is good enough marketing for me, and your website’s content sealed it. Didn’t even look further. I’m your customer now. And, personally, have always loved supporting other founders/builders building interesting tools and utilities.
Edit: I just realized this is not compatible with Intel Macs which I wanted to use on too. I didn’t read everything on the website, did I?
Suggestion: Please send me an email after successful purchase, so I have a record.
This might be what I've been looking for. On the first of every month I have Hazel put everything in ~/Downloads/yyyy-mm (previous month), with the intent to move each file to the correct project/area folder in my actual file structure. But I'm about 1.5 years behind on that...
Have you looked at competitors? If so, what are they? I haven't found anything that does this as elegantly as Fallinorg.
This is perfect for cleaning out my Downloads folder and adhering to the Johnny Decimal system (as a first pass, anyway). Neat!
I'm working on Macscope (https://macscope.app), a better Cmd+Tab for macOS. I built it because macOS window management feels slow compared to the keyboard-driven speed of a terminal or code editor.
It augments your existing muscle memory: a quick tap of a shortcut switches apps like normal, but holding it opens a powerful interface with features like:
Unified Search: Instantly find any window, app, or browser tab.
Scopes: Save and restore entire window layouts for different projects (perfect for after you unplug a monitor).
Placement Modes: Snap windows to screen halves as you switch to them.
The goal is to make the OS feel as fast as my other tools. I'm always looking for feedback on how to make window management less frustrating!
I’ve been building Flare (https://www.getflare.app/), an app for people with chronic skin conditions (eczema, rosacea, etc).
It lets you log symptoms and triggers, but the bigger vision is being able to discover patterns, ask questions about your own data, etc.
Being able to answer questions like “Do my flare-ups correlate with stress?” or “What foods make things worse?” backed with personalized data has been helpful with my own flares.
Still early, but curious to hear thoughts from folks!
TrailerSpoiler.com [0]
It annoys me how much a bad trailer can spoil the movie, so I made this platform to rate trailers how "spoily" they are and how good they are. To my surprise, you find some great trailers without many spoilers, but then you will have trailers which are basically a 3-min summary of the movie.

Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!
I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)
As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.

Neat idea, but how does that work? Can an app limit other apps? I didn't know it was possible.
I am working on FastFileLink (https://fastfilelink.com/), yet another file-sharing CLI/app that uses WebRTC for P2P transfer but exposes HTTPS links, making it compatible with browsers and tools like curl/wget.
It's ~90% production-ready. We use it internally to move files between containers and hosts (especially when volumes aren't mounted), and for WFH employees to exchange large files without a relay server. For huge files, there's resumable upload to our infra-backed server — fast global downloads included.
The CLI will also support receiving files via WebRTC, but that feature hasn't been released yet. It is open source (https://github.com/nuwainfo/ffl), but the README hasn't been updated yet and the code is not synced with the latest version (working on these).
Another production-used tool I'm working on is MailTrigger (https://www.mailtrigger.net/) — a programmable SMTP server that turns any email into a message on LINE, Slack, Teams, Telegram, SMS, or basically anything. If your app can send email, it can trigger multi-channel notifications with zero extra code.
Think of it as “SMTP to Anything,” or an email-native IFTTT/Zapier.
It supports JS and WASM for preprocessing, routing, and automation — you can write custom logic, auto-reply with LLM-generated messages, or forward alerts intelligently. We use it for price drop alerts, server health monitoring, and integrations with Jenkins/Sentry to push incidents to our DevOps Telegram channel.
Also experimenting with LLM-assisted rule creation: you can define notification logic in natural language instead of writing code — for example, auto-reply with an LLM-generated joke or handle customer support queries dynamically.
Docs are more complete than the website (which is still evolving), and the pricing page is currently a placeholder. Already running in production for us and a few early adopters.
I’m building a daily word puzzle game with a twist!
In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword.
You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got.
I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every day!
So far I’ve gotten really positive feedback and have around 100 people signed up to get notified. It’s been a lot of fun to build!
love the UI! one feedback I have is it would be nice to be able to use arrow keys on the desktop website to move the tiles
The UX is phenomenal. Easily in the top 1% of daily word puzzles. Love the concept, I'm sure it will do well at your launch!!
This is such a nice comment, and I only checked out the website because of your comment! I am glad I did. Indeed a spectacular puzzle.
That’s lovely to hear! Thank you!
playlin.io is super cool! Nice job! I’ll submit my game there when it launches :)
Thank you! Happy to feature your game, I've played a _lot_ putting together Playlin so I have a pretty good sense of what's out there.
Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once.
That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.
Thanks! I experimented with this but struggled making it feel natural on mobile.
I ended up implementing an alternate solution that I’m hoping solves for the same paint point.
My current dev build “merges” tiles when you connect them to complete a word. This allows you to move them as
I’m going to release a demo with that feature soon. My core playtesters seem to like it but I want to get more feedback on it from a larger group!
Working on a personal recruiter / talent agent for my smartest dev/product/design friends (and theirs) https://www.hedgy.works
Key problems we're solving:
- Everyone wants to be doing meaningful, fun work that feels like their "life's work". Few feel like they are.
- In recruiting, the AI spam problem is real and only getting worse, essentially killing the cold application pipeline. You need a referral.
- Optimizing your career feels like annoying politicking for a lot of the most talented folks who just want to focus on building cool stuff. But, as an employee, if you don't test the market (e.g. take a recruiter conversation) from time to time, your comp can really stagnate.

a fun side project to track Sumo stats.
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!
Sumo fan here, this is cool. UI is great. I assume you know about sumodb? I don't say that to discourage you, but people are tracking stats.
Since you are good at UI, here's something I would really like: a Natto-style page for each bout that I can manually page through as I watch the basho. Since Natto is underground, I have to watch the basho on NHK or Abema or via Kintamayama - all fine, but I miss the Natto graphics. If you could do that in a way that I could tap through each match, I'd use it every day of the basho and I think so would everyone on r/sumo.
BTW if you don't know what I'm talking about, reach out and I will explain.
Sumodb is great and still better in many ways!
I was testing something like this with https://sumostats.com/live (a second-screen style page, so you can quickly look up the current match and it follows along live).
But I think I know what you mean... I'll check out Natto graphics again (haven't seen it in a while) and will try make something up for next basho!
Given that people bet on sumo, wouldn't people pay a lot of money for your stats?
Haven't met anyone who bets on sumo so I don't know. The stats are out there, so I don't think its worth anything more than a bit of ui convenience
Continuing to do a lot of historical review of early AI stuff. Just finished the Semantic Information Processing[1] book edited by Marvin Minsky, and now I'm reading Volume 1 of the Parallel Distributed Processing[2 book by Rumelhart and McClelland. After that, I have Principles of Semantic Networks[3] by John F. Sowa queued up.
Along with all of that, still working on a lot of stuff using Jason[4] / AgentSpeak[5]. I created a fork[6] of Jason that is meant to be easier to integrate with Spring Boot, and to take more of a "run headless on a server" approach, which meant taking out references to a Swing based in-process logging/management tool. In place of that, I'm implementing a JMX based management interface, and recently I've started to work on replacing the old Swing app with a JavaFX app that can connect using JMX Remoting.

I love this! If you want to do a short book club or do a review after each book, I'm very down!
It's funny you say that. I already do run a weekly "book club" group, but it's at work at my $dayjob employer. And, for various reasons, we've drifted away from the book focus and turned into a more presentation/discussion oriented group. But I still love to read physical books, and wouldn't be opposed to trying to come up with something to structure some discussion around some of these "outside of work" readings that I do.
If you want, drop me and email (prhodes@fogbeam.com) and maybe we can set something up.
I'm trying to make an RF lightning detector small enough to trivially add to my motorbike.
I live in Viet Nam, and driving through bad storms this time of year is pretty miserable, and they happen fast and are local enough that weather prediction is not terribly useful.
There are a lot of problems with EMI. Lots of ungrounded brushed motors everywhere that make the RF bits hard. If I succeed, I'll publish the PCB designs.
I've also got some educational products in production right now, about Vietnamese history. I'd share a link, but my website probably can't handle the traffic right now.
Tech side project: crawlers that doomscroll job boards for me, and a Tinder clone that swipes through them. I recently broke out the actual automation logic into something more recyclable for scaling out to new targets (and broke out the HTML parsing for possible use outside my browser automation flow). Still figuring out how I want to handle datasources as both an API and a plugin architecture, but the goal is to eventually be able to configure searches through the API, to manually trigger and/or setup scheduled runs.

Personal side project: extensive cleanup of my family's place. I'm just now approaching a decent first pass at the outside, and have to tear apart a basement next. It's taken most of this year. It's not the specific reason I've farmed collecting search results off to a bot
For-fun thing: CTF puzzles. I'm not very good at them, but they're useful for other things. I fell down the scraping rabbit hole this way, and I'm currently using a series of them to finally get some exposure to Python. I also have a writeup half-written about this exact process
I'm working on Pruno (https://pruno.dev/), it's similar to Dependabot/Renovate bot but it removes dependencies instead.
My team suffers from dependency creep. As soon as your system grows, the number of dependencies skyrockets. In Python/Javascript projects it's especially hard to determine which dependencies are not used anymore.
Pruno saves time for your team by automating this work. It's still WIP, but I'd like to get feedback. How are you dealing with your dependencies?
I'm working on a bunch of small tools for musicians. I want to simplify complex musical concepts by giving visual feedback and minimal UI. All modular components built with pure JavaScript.
Here are some of my first results (free PWA):
https://fretool.dev-zoo.net (Fretboard visualizer)
https://atoy.dev-zoo.net (real time audio slowdown and looper)
https://harptool.dev-zoo.net (Harmonica helper)
Continuing to build https://crucialexams.com/, a platform that helps people prepare for IT certifications like CompTIA, AWS, and Microsoft/Azure. It offers realistic practice tests and study tools. I also have partnered with educators and universities who now offer it to their students and get dashboards to review student progress and identify where they are struggling.
I'm working on Botnet of Ares, a hacking simulator where you can exploit millions of devices.

I started a newsletter that tries to recreate the original magic of stumble upon. To feature cool random stuff from across the internet.
I believe the old internet is still alive and well. It's just buried under a mountain of shit.

Neat! I don't love newsletters though, any chance you may be publishing this using ActivityPub too?
(Sorry if this sounds entitled, it's a genuine "do you have plans" question)
i am subscriber #48. let’s roll!
ps: love the design of the page!
Such a good UI.
Working on real-time log visualization platform with wallboard/tv support, initially inspired by Logstalgia:
https://tailstream.io
Launched the initial version a couple of weeks ago and making good progress, trying to share as much of the process as I can on X.
Backend API can be used by any client, but I also built an open source agent in Go that makes setup really easy.
Currently working on a proper log viewer, alerts and visualization improvements.
Please show this to AWS. CloudWatch is such a pain, arcade visuals is what I want, if I have to look at logs.
It's been a while since I've used CloudWatch myself. How would you expect this? IE would you lean more towards having a lambda/firehose that forwards events to to the API (which is [public](https://tailstream.io/docs/api) by the way!) or would you expect some kind of agent / connector to run that automatically pulls the logs from CloudWatch?
I've been contributing to a project called Folk computer[1]. It's focused on creating a physical medium for computing (think printing out a program, which is then tracked by the computer. There's some really cool spatial interaction that happens). Folk v2 is currently in development, so I've been digging into the guts of the datalog-like engine. It's been a lot of fun to pick up C and see it applied to a project I can directly interact with!

My one man side project is Prisme Analytics: an high-perfomance, self-hosted and privacy-focused web analytics service.
I'm working on improving UX and simplifying deployment a lot. In the next release, a single docker run will be enough to get a working web analytics service with minimal resource usage.

Kanji Palace - https://kanjipalace.com
I'm building an app to help people memorize Kanji by turning the characters into vivid, memorable images with accompanying mnemonic stories.
I think AI image and video models have reached a point where they can offer a completely new approach to language learning.
Next, I'm planning to add features that use AI to generate comic strips (using Seedream or Nano Banana), songs (using Suno) and videos (using Veo 3 or Seedance) to make learning Kanji even more engaging.
Solo-building this project for some time, going to launch the first version in a week or so!
https://elmo.dev - a tool that automatically builds a searchable knowledge base around your project based on your conversation with coding tools.
It works automatically and doesn't require your attention. To build KB it uses same tool as you (claude/codex/gemini) so it uses the same quota and you don't have to pay additionally for the AI running it.
The result is ./elmodocs directory in the root of your project. You can reference CLAUDE.md/AGENTS.md/GEMINI.md to this directory or directly include the whole directory or its parts into the coding context.
I'm finally organising 20 years of voice notes. Some were quite outdated - I probably no longer need the mozzarella cheese I reminded myself to buy in early 2008.
To organize them, I'm writing a Python Qt application with Claude Code. It started off as vibe coding, but I'm now developing it using processes very similar to those I would use when managing software teams. I've picked up a lot of good tips about that here on HN. I've got Whisper, and fallback online services, transcribing the audio and summarizing it and adding tags. After much UI experimentation, I've landed on something that looks not unlike an email client, with tags in the left pane, a center pane which lists transcriptions and notes about each audio file, and a right pane with more detailed information about the selected audio file.
Next step is to serve it all as a model context protocol server - I need to pick an agent.
this is really neat.
We are working to build Notion, but for books. It is a personal book diary to collect your to-be-read and smart sort them, as well as log your reads and use that data to build a profile of your book dna in order to connect you with new books/authors that your book twins love.

I'm working on 2 projects right now:
1. Fluxmail - https://fluxmail.ai
Fluxmail is an AI-powered email app that helps you get done with email faster. I think there's a significant opportunity for AI to change the way we use email, and I'm experimenting with ways to improve the status quo. I'd love to hear what features you'd like to see in such an app!
2. ExploreJobs.ai - https://explorejobs.ai
This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.
I built a fantasy football rankings app using claude code, and it has been blowing up in the fantasy football subreddit. Funny enough, it's forcing Yahoo to change their site and improve their layout which ruined all my automation. Surprised how much traffic it's receiving every week just for a better layout.

I've been building https://resolver.one - a DNS server that returns GeoIP data as TXT records. Query an IP directly as the hostname (e.g. dig TXT 8.8.8.8.rslvr.one) and get back country, ASN, etc.
Always been fascinated by repurposing established protocols for unintended uses - DNS is everywhere, passes through firewalls, and has built-in caching. Seemed like a fun way to deliver location data without HTTP APIs.
Super niche, definitely a bit odd, but that's the appeal.
Neat idea, even if it doesn't end up going anywhere.
Out of curiosity, are you able to share what your source of data is? Isn't GeoIP data typically licensed?
Data source is IPinfo Lite MMDB file, which seems to be offered freely without restrictions. I'd love to offer comprehensive GeoIP attributes but I'm afraid to even ask how much the DB download of that costs... I'm working on supporting new data sets now like security CVEs, shodan integration, etc.
IP2Location LITE has free data on ZIP code and timezone for enrichment. You can consider it too.
I have been building https://github.com/zayr0-9/Yggdrasil
It started as a solution to LLM front ends having terrible native branching features. But slowly I realize most of our data will be going through LLM's so Yggdrasil is evolving into a platform which consumes all your LLM queries, while keeping it easy to query and reference.
And now I have begun to realize how detrimental LLM assisted coding can be to someone who starts depending on it too much, so Yggdrasil is a bet in the other direction as compared to mainstream. Instead of agents/AI doing everything I believe human + ai assistance will win in the end.
Yggdrasil has a simple agent called Valkyrie, so they have their place, but that I believe should be the last step, after the developer has discussed and planned thoroughly through our tree interface, Heimdall.
And if someone replaces the dev, they can browse their conversations with the LLM, observe their mind map, what questions they asked, what extra things they considered (branches), the whole thought process easily navigable and visible.
Personally after using Yggdrasil, I feel quite confident in using the LLM, as I can ask all the silly questions I want, without worrying about context pollution. It aligns really well with the natural exploratory tangential thoughts we have when trying to find solutions or learn something.
I am building LookAway[1] - an antidote to seductive screens. Many people have been facing issues like eye strain, digital fatigue, CVS, posture issues, and more due to prolonged screen use and I aim to solve it with this product. I believe managing screen time is as important as managing sleep (if not more).

As someone who's curious (I see lots of room for improvement in terminals!), I can't tell what this does from the website, other than the ability to load and view 3d models.
Ah right, that’s just the “wow factor” hook. If you scroll down a smidge you’ll see a 3-minute video trailer.
The Media page also has a 15-minute demo comparing Terminal Click against suckless.
Of course I just need to do a better job telling you what we’re all about without the need to watch videos.
Nice work! so much cool stuff happening in terminals these days

A webscraping / data pipeline to get the .pdf "Explanation of Benefits", "Proof of Coverage", and "Drug Formulary" for every Medicare Advantage plan in the USA
These docs are gonna be used in a product for medicare brokers (if you are/know one please reach out open enrollment starts Nov.1!), and the pipeline is horizontally scalable to ingest updated 2026 plans overnight @ start of open enrollment (though some companies are posting updated plans earlier)
There are some clever tricks at play but mostly it's bog-standard browser automation; I'm also in an interview process with 2 entities (one funded startup and one massive corporation) talking about web automation roles, and while it's frustrating that they're moving so slowly it's working out to give me time to build this well.
Trying to re-legalize "neighborhood commercial" by right in the city I live in. Things like corner stores or small barber shops or coffee shops or converted restaurants. ACUs or Accessory Commercial Units, home conversions... different ways of doing it.
Great. I assume you live in the US ? Your urban planning law are atrocious. In countries like thailand for instance it's very common to have a shop in the house. Things go nicely and it's more lively. Good luck, that a good project at the root of so many issues
If you have a shop in a house in Thailand and a crazy person decides he likes the shop and stays in front of it all day yelling, in Thailand, the people in the house call the police, who make the crazy person leave. In the US, every person, crazy or not, has Freedoms and Rights, and the police won't do anything to help the people in the house because it would be wrong according the the US way of thinking to curtail the Rights and Freedoms of the crazy person (who is yelling all day near the shop, which is very near the house).
Consequently, owners of houses in the US try to make it as boring as possible and as useless as possible for any crazy person, homeless person or group of teenagers to hang around near the house. One way they do this is to make sure the house is surrounded only by other houses, trees, parking spaces and roads (and there is not anything as useful or interesting as a shop in easy walking distance).
This is a bit of an exaggeration, but it is directionally accurate.
No, it's mostly just car-brain where people think that cities should be designed around cars cars and cars, and then if there's room left over, maybe some shops and homes.
So they worry about a neighborhood shop taking up the precious, precious parking spots or causing 'traffic!' even if in reality it reduces it because people have something close by their home they could even walk or bike to.
So the root problem is not the American commitment to rights and freedoms (especially for the disadvantaged) that Americans discuss constantly -- often in heated, emotional or abstract terms and sometimes in frankly ideological terms. According to you the root problem is an irrational and destructive commitment to automobiles, which (at least after the 1960s) Americans talk about much less than they talk about rights and freedoms -- and when they talk about them, they talk mostly in pragmatic terms, e.g., miles per gallon, turning radius, maintenance costs and space for car seats for children.
I live in a city of 100K people, where there really aren't that many visible people with mental health issues or drug problems. I also go to a lot of city council meetings and hearings and observe local social media.
It's the cars.
Do people often yell at stores in commercial settings?
I recently released JazzEar, an iOS app for ear training. Specifically focuses on improving recognition of chord progressions you would hear in jazz standards.
https://jazzear.com/
Now I'm working on a smaller app for jazz musicians to manage their tune list and act as a tool to help practice and review tunes. I wanted this app to tell me what tunes on my list I haven't played in a while (and might forget), or try different keys or exercises on the tune and track what I found difficult.
I left my job to work on my side project (MCP-B: https://news.ycombinator.com/item?id=44515403) full time. I set out with the goal of making the ability to vibecode a webMCP server for your website and inject it via userscript.
While building that, I basically wrote a modern version of Tampermonkey with its own marketplace built in. So you can vibe code any userscript and publish it to the marketplace all within the extension.
The automation stuff is still the core value-prop, but this is a fun bonus feature while I work on solidifying the automation features.
I'm writing a HN post for it. Excited to show everyone in a couple weeks here.
After that Deus Ex remaster fiasco, I wanted to see how the famous Unreal 1 dithering technique would look on Quake's software renderer. Getting a clean build of it on Linux was fun in itself: https://github.com/klaussilveira/exp-quake

Our patent-pending neurostimulation builds on over a decade of research in slow-wave enhancement, and more than 50+ published peer-reviewed papers.
Today we're building our last 3D printed unit. In October we start our first tooling run.
The first thing I need to see is what it can achieve.
30% increase in slow-wave activity. 15% decrease in early night cortisol 14.5% increase in HRV during stimulation
It's all in the research.

I'm still working on Danger World (https://danger.world), my casual 2D narrative adventure with turn-based RPG elements. Built in Flame, on top of Flutter for iOS, Android, Windows and MacOS.
We're getting close! It's just a matter of polishing and polishing and polishing, but I'm really excited about how close we are to launch.
Https://KushtyBuckRecords.com Been thinking a lot about tools for modern musicians/artists/producers. Not tools for creating the music but tools for communication. Email subscriber lists, event creation (image and text) combined with ability to generate QR codes and send them with easy to use dashboard, some kind of insights into the QR scans, merchandise (integrations with Shopify), hn style link aggregation around music.. been building it with my son who also becomes my product manager since he the one using the tools. For now a private repo consisting of a rails API and a react TS frontend app. Everyday I come up with some small improvements in my head but alas not enough time in the world. With the day job an all, this is purely a passion project and a way to help my son follow his passion, putting on house music events and DJ/producing. If anyone interested, plz reach out contact@kushtybuckrecords.com
- Active recall studying app that allows a user to practice active recall[0]. The app hides user provided content at first and asking the user to try to remember all they can before reading the content. Then the user goes through the material slowly revealing each paragraph from their input. At the end they try to actively remember what they learned and can even compare to what they knew at the start.
- Mixtape sharing platform for midwest emo[1] which is a genre I've really gotten into over the past few years. The community is pretty strong on YouTube for creating "mixtapes" so I wanted a spot that was just for these videos.
- PhotoForge[2] Photographer's companion app which can help me choose photos using a Tinder-esque swiping mechanism. It also has some AI stuff for generating Instagram descriptions. Finally has a watermark tool. Still trying to think of other stuff to add. This was an AI code weekend project so it's like a house on stilts at the moment but I plan to give it some more love soon

I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1].
It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integration.
I posted about it[3] on Last FM's subreddit and I was pleasantly surprised to see that a lot of people shared their labels on the comments and seemed to like it.
I'm currently working on language detection, I think it'd be cool to get a language breakdown of the songs you listen to and for that to be part of the displayed items within the label. Something along the lines of EN- 80%, ES- 15%, FR - 5%
I've also tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up")

Thank you for giving it a try!
I’m building TypeQuicker: https://www.typequicker.com
Typing is an extremely underrated skill and especially in the age of LLMs, it is the bottle neck in a lot of cases.
I’ve never been fond of existing typing apps; excessive ads, typing random words, etc so I built my own.
You can practice typing code, use your own text, etc
We have a paid plan for features where you can type natural text that targets your weak points (via SmartPractice) and many others. Other than that, it’s both free to use (and ad-free)
nice!
i open and close parens, brackets and curlies at the same time.
is there a mode/setting to capture this intent?
Hi - thanks for checking it out!:)
Sorry, I’m not sure I follow - do you mean you type: () and then type within them?
exactly.
AFAIK a lot of programmers do this before their editor would auto close them and so its now muscle memory to

That’s great! Going to give it to my kids to try.
Thanks! Any feedback is welcome :)
I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard.
Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job monitors), I'll be able to start building a proper terraform provider, and audit logs.

We're building a monster trainer where you can actually teach your monster moves. Think like Pokémon the anime, but for real: https://youtu.be/ThOCM9TK_yo?feature=shared
Behind the scenes, we're doing real time code gen to power the monsters!
Would love feedback!
ok this is really cool. do you do procedural animations as well or it's still animated library of moves you blend?
No procedural animations yet, but soon we want to get there. We also want to do procedural VFX. There is a lot of meat in there!
OOh I have a great connect for VFX if you need a sound engineer

Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer
Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things.
Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of hints (know of UK, Norway and might have found for France).
Would be great to know which pubs have gluten free beer. I recently became gluten intolerant, and it's ended my 40 year beer career!

I've been working on a map that shows which neighborhoods in a city are nice/not nice with a short description.
Whenever I visit a new city, just looking at Google Maps is pretty meaningless - it's just a bunch of gray land and streets. I end up looking up Reddit posts for where to go, searching for crime maps, trying to find annotated maps, etc. to get a better idea of where to visit in a city (or even live, like when I had moved to Austin). AI generated scoring and descriptions, while imperfect, have already helped me when visiting SF recently. Early stage, so please help with submitting corrections, if you'd like!
I like the idea! In my opinion (looking at SF) it’s still too low resolution. SF in particular can vary greatly in safety, walkability, etc. even a few blocks over within a neighborhood.
Very cool! I really like the idea, the way I'd develop this further is by having live crimes reporting on it so that you know which streets to avoid , similar to what waze does where people report items
I have a similar problem where I want map-type data, but it's subjective reviews that couldn't go in OSM directly.
Are you using OSM's nodes and relations and such as foreign keys for your own overlay, or just lat/long?
Just using lat/long points for the polygons.
Most of our jobs consist of working with tools. Yet it’s very hard to get insights into which tools are required most, are growing in your area, etc. So I decided to keep track of tools and technologies mentioned in the data space by keeping track of job openings for the last two years. Now I’ve opened up that data set. Here’s an analysis for jobs per data warehouse: https://selectfrom.work/insights/data_warehouses

I’m currently hacking away at a project which turns your keyboard into a clipboard manager, password vault and barcode reader as parts of it. I just need to come up with a better name than totally normal keyboard (:
Inspired by a friend getting a random email and it sparking a memory for me: https://pageday.org, a global message lottery where each day a random message is drawn to be the homepage.
What happens if the selected message is unpleasant or against your political views? Do you curate submissions? If so how?
Yeah that's a good question, and something we haven't codified.
Odds are that we'll curate quite heavily to keep it interesting and maybe along similar guidelines to hn with "anything that gratifies one's intellectual curiosity" rather than just "anything".
Mostly organizing my dotfiles across Windows, macOS, Linux and BSD, however, I have really fallen for Ansible. I discovered at work awhile back, but was able to grok how to make and run a playbook, and I've been hooked since. It also finally allowed me to click the difference between Imperative and Declarative programming!
Careful, not all ansible is declarative or idempotent. Lots of foot guns exist, still a valuable tool
I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output.
The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.

I'm trying to build a next gen quickbooks competitor.
Something that doesn't nickle and dime you, very cheap (perhaps even open source), has all of the extensibility of a modern ERP, a great UI, and handles complex use cases (revenue rec, expense management, inventory cogs, etc).
I feel like this is solving a real problem, but have no idea how to break into the industry. Just trying to solve my own problems for business accounting but would be nice to know other folks would be interested.

I'm trying to incentivize people to build IRL communities instead of AI-related apps because the demand for human interaction FAR outweighs the supply. My platform (https://onthe.town), is basically Shopify for social experience clubs. Anyone can start a club and create events based around bringing random people together IRL based on shared interests. You get your own website and infra that handles signups, payments, and matching.
It's largely based on platform-izing the extremely popular Timeleft app that simply matches 6 random people for dinner. With onthe.town, anyone can create a Timeleft-like app around any concept they're interested in. Some clubs people have created include a golf club (get matched with 3 other people to play golf with), a vinyl record sharing club, a lunch club for biotech networking, and a club to meet other parents for dinner.
Love the idea. From the FAQ section on the website:
> Organizers can keep a portion of sign-up or event fees
Isn't this a given? Don't event organisers expect to keep the entire sign-up fee for themselves when they host an event? The website banner reads:
> Build an IRL community. Get paid for it.
I was under the impression that onthe.town will pay the organisers from their own pocket for organising the event, but that does not seem to be true.
There was a startup in my region who got popular with the simple idea of having a website/service that manages simple events, like talks, presentations etc.
I think it started with mostly students using it because there used to be a lot of university-related events like these, and eventually they’ve become the standard platform for that, at least in the State. It was all pretty simple, it managed payment etc. and you’d get a QR code by email or in the app that could be scanned in the entrance.
I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made up of jobs that declare their input and output partition deps, so that they can be automatically fulfilled, enabling kubernetes-like continuous reconciliation of desired partitions.
This means, instead of the answer to "how do we produce this output data" being "trigger and pray everything upstream is still working", we can answer with "the system was asked to produce this output data partition and its dependencies were automatically built for it". My hope is that this allows the interface with the system to instead be continuously telling it what partitions we want to exist, and letting it figure out the rest, instead of the byzantine DAGs that get built in airflow/etc.
This comes out of a big feeling that even more recent orchestrators like Prefect, Dagster, etc are still solving the wrong problem, and not internalizing the right complexity.
Very much agree that to this is the direction data orchestration platforms should go towards - the basic DAG creation can be straightforward, depending on how you do the authoring - (parsing SQL is always the wrong answer, but is tempting) - but backfills, code updates, etc are when it starts to get spicy.
I think this is where it gets interesting. With partition dependency propagation, backfills are just “hey this range of partitions should exist”. Or, your “wants” partitions are probably still active, and you can just taint the existing partitions. This invalidates the existing partitions, so the wants trigger builds again, and existing consumers don’t see the tainted partitions as live. I think things actually get a lot simpler when you stop trying to reason about those data relationships manually!
Wow, neat idea!
Is this going to be proprietary or OSS?
Definitely open source!
I'm making a visual explainer site for PyTorch functions:
https://whytorch.org/
A great example of how it works is http://whytorch.org/torch.amax/
Clicking items in the tensors explains where they came from and where they are used in the output. The input tensors can be modified too.
It's a one-man side project that's been half building the site framework, and half re-implementing pytorch functions in javascript. Plenty more functions to go, but hopefully people can already find it useful. I'm planning on doing a Show HN once I've added ~10 more functions.
Posting this from a throwaway account because my main account is locked due to `noprocrast`!
This looks neat. Great idea!
Perhaps `dot`, `cross` etc might be useful additions.
I've just added the dot, cross, and Kronecker products - thanks for the suggestion!
I’ve been working on a few utility libraries to make it easier to develop web services, basically exporting packages that I find myself using or rewriting often and exporting them as their own modules.
I recently published https://github.com/hxtk/sqlt for SQL query generation with Go templates.
I’m working on https://github.com/hxtk/aip as a collection of libraries giving safe default choices to implement Google’s API improvement proposals in ConnectRPC services. It borrows (with attribution per the license) an unexported implementation of AUP-160 filters from the LuCI project, and I intend to expand it to support data sources other than SQL databases and page tokens, and it also exports an implementation of AIP-161 field masks (which have different semantics compared to standard field masks) and middleware to help with using them for AIP-157 read filtering. I intend to export more middleware that I use frequently, but I don’t know if it’ll live in this module or its own yet.
I'm working on an AI thumbnail/graphics maker using the various image models.
https://thumbnail.ai/
You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.

I'm putting a bunch of security tools / data feeds together as a service. The goal is to help teams and individuals run scans/analysis/security project management for "freemium" (certain number of scans/projects for free each month, haven't locked in on how it'll pan out fully $$ wise).
I want to help lower the technical hurdles to running and maintaining security tools for teams and individuals. There are a ton of great open source tools out there, most people either don't know or don't have the time to do a technical deep dive into each. So I'm adding utilities and tools by the day to the platform.
Likewise, there's a built in expert platform for you to get help on your security problems built into the system. (Currently an expert team consisting of [me]). Longer term, I'm working on some AI plugins to help alert on CVEs custom to you, generate automated scans, and some other fun stuff.

It's a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Soon with multi-currency support. Currently targeted for desktops.
It's interesting in many way. Using double-entry (it's a perspective shift and a power tool), the challenges and advantages of building local-first app, UI/UX & visualizations, privacy and more. For personal apps, local-first is a good fit.
Tinkering with a tiny macOS app that gives me proactive reminders about the low battery and imminent shutdown.
Standard system notification comes at about 10%, and most of the time, in my case at least, whenever I miss that, the result is "laptop shutdown amidst an ongoing video meeting" or something like that. (Basically, too late before I act)
Just so that I don't miss the reminders, the app will show an overlay window with some text, following my cursor, and a custom sound.
I vibe-coded a version this weekend and can see it being helpful already [at least to me].
Nothing extraordinary like yall.
I've been down a prime numbers rabbit hole. Trying to see the largest prime I can generate in a browser.
An AI interface to a point-of-sale (POS) system: https://github.com/paulmooreparks/PosKernel
I'm actually in the middle of a complete redesign of the AI layer, but there is a POC video linked from the GitHub README that demonstrates the interaction I'm going for using an earlier version. The POS is a very bare-bones system where the "kernel," as it were, is implemented in Rust. There's an MCP atop that to allow the AI and UI layers to drive the POS. Stores may be implemented as extensions that plug into the POS kernel, and that's where language, currency, item databases, and such are defined. The AI cashier knows what items are for sale, how to modify items (in a restaurant context), how to translate from other languages, how to interpret what the customer actually wants, and seamlessly lead the customer through a transaction.
The current code is quite ugly and full of a lot of unfortunate hacks, but it was a good education. The new design puts the AI much more in charge, without as much code-level orchestration. I'm applying a lot of my knowledge from the retail POS and self-service checkout domains to this, as well as learning a lot about applying AI to a "legacy" software domain.
Updating my validation library for python, koda-validate (https://github.com/keithasaurus/koda-validate).
Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types.
Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Would love feedback!
Pydantic already covers type-driven validation and it works well enough. What is the main value add in Koda? Just curious.
It's not the core of koda-validate, and yeah lots of libraries have a similar capacity. Feedback I'd be interested in is if there are gaps.
In general the value prop of koda-validate is that it turns validation into typesafe building blocks, which makes validators very re-usable -- and flexible. Some other notable differences from pydantic are that it doesn't `raise` on validation errors, you don't need a typing plugin, and it's fully asyncio-compatible.

I have made a Bürgeramt appointment finder. It was down for a few weeks after the city of Berlin changed its anti-bot measures. I just released an updated version that works again: https://allaboutberlin.com/tools/appointment-finder
My citizenship wait times page (https://allaboutberlin.com/guides/citizenship-wait-times) has also gotten enough feedback to be useful since its release last month. I'd like to make it more useful with better visualisations.
Now I'm working on another iteration of my health insurance calculator (https://allaboutberlin.com/tools/health-insurance-calculator). It's kind of a big deal both because it's a huge financial decision for recent immigrants, and because it funds a big chunk of all the free stuff I'm putting out. This is especially important with ChatGPT and AI summaries halving my traffic. This iteration will recommend health insurance combinations that work for a visa application and for a long-term stay in Germany. It will provide far better explanations.
At the same time, I'm testing a new insurance broker with far shorter response times, so people can directly ask an expert to help them choose. They're reachable via Whatsapp, and that made a huge difference in how people get advice. It worked so well that I want to do the same for other topics. I'm already talking with an immigration lawyer who's interested.
I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.
Very interesting idea. Good luck!
I might be taking a contracted job to help provide AI/ML guidance for a friend's company here soon, but all I really do is use ChatGPT/Claude Code a lot and don't really have explicit AI/ML tool building experience. They know this and mostly just want me for competency and comfort going from 0-1 with a new project, but I'm still pretty nervous! So I'm trying to conjure up some simple ideas to inspire me to learn :)
Currently trying to predict student absenteeism in the future based on historical indicators with synthetic data using basic ML modeling and then using LLMs to generate helpful guidance for relevant parties. Basically letting parents know there's concern and citing leading indicators.
Not sure what I'll do next, but hoping to come up with a few other ideas to put my mind at ease. It's fun having some actual motivation to keep up with the current hype instead of just being a consumer, though!
biscuit-based identity and authorization
I’m working on https://www.hessra.net/, an identity + authorization service built around [Biscuits](https://www.biscuitsec.org/) instead of JWTs. The goal is to decompose auth primitives so they’re easier to use in service-to-service cases, while also showing off what Biscuit tokens make possible.
JWTs feel like problems waiting to happen. I think biscuits give stronger guarantees and are harder to get wrong.
One piece I’ve shipped is an identity token that can be delegated offline. For example, “company:alice” can delegate to “company:alice:agent,” and that token can then be used to request an authorization token. This makes for a neat API key model: you can issue a simple opaque identity token to your customer (e.g. “customer123”) without having to maintain a DB of hashes/expirations, since those are encoded into the token. Later, you can upgrade security by exchanging the identity token for an authorization token, or let customers delegate access (e.g. “customer123:marketing”).
I’ve also been experimenting with higher-order authorization flows:
• Service chains: each step in a request’s path (edge → app → DB) can add attestations, so later services can validate the full chain.
• Multi-party authorization: requiring two independent services/orgs to co-sign an authorization token, useful for cross-org or on-prem deployments.
Right now I’m building an OAuth 2.1 profile where the identity token replaces a refresh token and the authorization token stands in for the access token. I’m especially interested in hearing where people find OAuth clunky in practice, or stories from folks who’ve built auth systems with other token types (macaroons, biscuits, etc.) or for use cases where OAuth didn’t fit well.
Are Eclipse Biscuits related to Google Macaroons? https://research.google/pubs/macaroons-cookies-with-contextu...
(what a word salad that is...)
Biscuits are in the same family as macaroons in that they are bearer tokens that can be attenuated offline, but they go further. A biscuit carries a chain of signed “blocks” that can contain facts, rules, and checks in a small Datalog-like logic language. That lets the token itself express richer authorization context, not just restrictions.
Key differences from macaroons:
- Crypto model: Macaroons use HMAC, so every verifier needs the shared secret. Biscuits use public/private keypairs so any verifier with the public key can check validity.
- Expressiveness: Macaroons only add caveats (restrictions). Biscuits can encode facts, rules, and checks, enabling more complex policies to travel with the token. so you can attest and attenuate (and do some other tricky stuff if you want)
- Delegation: Both support attenuation, but biscuits do it with signed blocks that are verifiable and can be chained across services.
So conceptually similar, but biscuits aim to be more decentralized and policy-rich.
On the side, I‘m building a platform that allows to run MCP servers on demand, making them reachable under a public URL, but password-protected. You also get an embedded VNC viewer, and thus you can watch what an AI-agent is doing with it.
This makes it possible to use your own, dedicated MCP server instances from, for example, n8n workflows, without thinking about infrastructure.

I’m solo-coding the clear commercial project smmdealfinder.com which is not ground-breaking or amazing as these other great projects here, but its been an amazing journey for me personally for the last 18 months and has developed me probably from a junior engineer to senior+/staff.
Whilst I’m recently really critical of most AI posts here, this wouldn’t have been possible without AI, but mainly because AI could feed my curiosity and barely any riddle was unsolvable, when I put it into pieces and combined it with debugging (and checking docs). Actually most riddles on my level weren’t unsolvable before, but AI reduced the friction and speed of learning for me. This actually goes beyond coding. In life I just ask and learn a lot about, washing, cooking and domain-specific terms.
I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 .
There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just managing files instead of creating a new compose-like DSL. But even if it doesn't become popular I'm just happy I don't have to manage my homelab with Ansible anymore :) .

Working on a chess / poker hybrid.
There was "choker" back in the day, which I actually never heard about since I wasn't into chess back then. But (1) there was no web version, and (2) it had a specific gameplay that seems too slow for my taste. My version is highly customizable on the setup/rounds/rules, too. From my research, the original was also overrun by bots.
Looking up choker online I found this reddit thread:
> It’s a cool concept, but terrible app design and it’s all just bots you connect with, making it terribly easy to win almost every game
It sounds like this game needs a better AI opponent then? I don’t know anything about this game but something that learned from your gameplay and figured out how to beat you would be very cool.
I already have a better chess engine at different skill levels for 1-player mode. For two human players, I plan to start with sending a link to a friend given there won't be enough random players on the website to find one in real-time.

I'm working on exploring an exploit in physical security systems that I haven't seen anyone investigate before (at least, not published on the internet). It's involved an interesting combination of reverse engineering, pentesting and regular prototyping/hardware development.
Currently writing a run-through of it to publish on my website. I'm not sure how secretive to be - I think I just want to be the first to actually release my findings. In my post I'll detail the steps to reproduce my results so more people can look into this.
So far I haven't found any critical ways to (ab)use this access control system weakness, as it only typically applies to the outer layer of physical security.

I'm working on Happy Coder, an open source Codex and Claude Code native mobile app (plus a web app).
Happy lets you spawn and control multiple Codex/Claude Code sessions in parallel. Happy Coder runs on your hardware, works from your phone and desktop, costs nothing, End to End encrypted, and permissive MIT License.
https://github.com/slopus/happy
Happy Coder is a unix style "do one thing well" project.
The goal is zero workflow disruption. I want to be able to run CLI coding agents on any internet connected computer, and control them with my phone. Happy has a command line wrapper for Codex and Claude Code that let you start a session in your terminal, and then continue it from your phone with real time sync. So type in your terminal and see it on the phone, type into your phone and see it in your terminal. So you can switch back and forth.
There is an optional voice agent some contributors have been hacking on that lets you talk to the voice agent first, and the voice agent then writes prompts for Codex/Claude Code and answers questions about what the coding agent running on your computer is doing/did. The voice agent feature is pretty neat, but in my opinion needs a bit more iteration, so any ideas or help would be awesome.
I’m building a text editor inspired by ed, but instead of editing files on disk, it edits live network flows. In this model, files don’t exist as static objects—they exist in motion.
Creating a file generates a self-sustaining pattern of packets circulating through the network, and editing it changes the flow itself. Multiple users can edit the same file simultaneously, because the file isn’t tied to any machine—it’s in the network.
The interface is familiar if you’ve used ed, with commands like append, delete, and substitute, but behind the scenes it’s all live traffic. You can even discover existing flows and jump into them in real time.
It’s a Linux proof-of-concept using raw sockets, and the goal is to explore what files could be if we thought of them as living, circulating processes rather than static storage.

Another project of mine is to play music from my audio CDs by myself.

The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.

I am working on my Go UI library called gooey [1] which aims to be a one stop framework to build webview/webview apps in Go and WebASM.
It started out with bindings for the DOM, Web, and Browser APIs, but as of today I now have custom Web Components support (which is a big deal considering Go's type system quirks).
Tomorrow I'm gonna polish some of the UI components and start refactoring my git-evac [2] repo management tool which is the first app using the gooey framework.

> Components are bad for web accessibility (aria- property fatigue).
I've been using web components as a vehicle to automate and auto validate accessibility aspects as much as possible, because I think the only way to truly make things sustainably accessible is to find a way to unburden the developer by either inferring as much as possible or making validation a natural part of development rather than a separate testing cycle that will invariably cause accessibility support to become out of sync.
It sounds like you might have similar concerns. Do you have any insights to share along these lines for Gooey?
The UI components that I wrote initially are just wrappers for the Browser provided input/form elements. As I'm relying on webview/webview to build desktop apps out of it, that also kind of implies WebKitGTK4 on Linux, WebKit on MacOS, and WebView2 (Edge) on Windows.
These work quite nicely together with a screen reader because you don't have to intercept the focus event (or others) that people browsing in caret mode or similar would use to navigate the page.
Additionally I decided to make single page applications using a main and section[data-view] elements so that the HTML and CSS alone is enough to hint screen readers on what's visible and so that there are no javascript codes necessary to tween things around, the JS/WebASM side of things literally just sets a data-view property on the main element.
The whole idea behind gooey and the way it is structured is:
- all states must be serializable in HTML
- Static HTML and CSS makes the page usable (apart from web forms and REST APIs, that's developer provided code)
- Dynamic WebASM on top essentially translates the DOM to be interactive, so that things can be animated based on changing data or streams coming from the backend. All interactivity is rendered directly into the DOM, so that it can be serialized again at all times.
- Communication between Client and Server is JSON or any other Go implemented Marshaller, and using Fetch API behind the scenes.
I decided on purpose to not provide XMLHTTPRequest and other old APIs because I'm relying on WebASM and "modern Browser engines" anyways. This way I kinda force users of gooey to use modern JS from the WebASM context and I save a whole lot of trouble with compatibility issues (and don't get into the unsemantic div fatigue like React does, for example).
Looks great! Wish Go wasm modules were smaller.
The bindings should also work with tinygo's compiler if you're careful with deadlocks (see docs/ERRATA.md).
Haven't tested the typecasting that's required for the components yet though, they might break because of some generics quirks (e.g. Wrap/Unwrap helper methods).
That’s a great name.

ViewMD - A Mac Markdown Viewer app
It looks like Markdown is having a bit of a heyday with it being the default mode of docs for AI coders. And it became apparent that there is no simple, but powerful Markdown viewer for the Mac, so I made one.
It supports all the usual Markdown formatting but also diagrams and equations so you can get Claude to not only write up your system docs but also supply a diagram of the database structure, logic, or AWS services.
It would be cool if you gave it a go :-) It is in the Mac app store "ViewMD"

It is a desktop app built with Electron and React. I built to help newlywed couples to quickly sort thousands of wedding photos with a Tinder style swipe UI. It is offline first, fully private, and offers one click export of your selected pictures.
I started building it earlier this year after going through my own wedding photo experience and realizing how overwhelming it can be. I saw my wife dragging and dropping photos from one folder to other and thought there has to be a better way for non-photographer folks.
Right now, I have a working prototype, a landing page live, and I am testing distribution and feedback from early users.

I'm pursuing my vision of "music-i18n": Open source music software that works for microtonal music and worldwide musical cultures.
It's not a from-scratch effort, quite the contrary: I'm trying to tie in existing music standards (MIDI, MusicXML, SMuFL, MEI, etc.) and ensure that FOSS systems (MuseScore, Verovio, smaller components) implement enough of those standards to support music-i18n.
Sometimes, this also includes extending the standards themselves when they are not fully capable of representing some non-mainstream musical aspect. For example, MusicXML lacks the ability of representing multiple accidentals per note (whereas MEI does), which is a must for microtonality.
I started down this path around 2018, as a music player who got interested in arranging Arabic songs in a "Real Book" style. It opened a giant rabbit hole that I'm still far from having fully explored.
Now and then, I collaborate with other devs who are interested in adjacent topics. I would love to hear from some of you here!
As an entry point, I recommend checking out the "progress report" I wrote last October: https://blog.karimratib.me/2024/10/01/music-grimoire-progres... - I'm currently drafting this year's update. My main demo is at https://blog.karimratib.me/demos/musicxml/
https://spanara.app
Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI.
I am currently working on a new mode that is more like what played walking around: a few rounds in rapid fire, very little time to think before the next round.
Seems like a really small dictionary. Many/most of my guesses (and Gemini's) don't work.
Yeah, sorry about that, and thanks for the heads up!
I've struggled with the dictionary a few different times. Here's to hoping the 12dicts wordlist 2of12inf is a better choice than my previous ones :D
The new dictionary is live!
Often, when I use generative AI to produce videos, the results are close to what I envision but rarely capture my imagination exactly. Prompting the AI to fix specific details can be a cumbersome and time-consuming process. To address this, I'm developing solutions that make the creative workflow more intuitive. So far, I’ve built an app that allows users to provide visual clues as guides, along with a 3D environment where the camera can be freely manipulated within the generated scene.
The community is moving fast though. Now higgsfield allows using arrows and pointers to edit the video but so far, no one is doing a good camera control visually.
I’m writing a Python framework to create Python home automation scripts driving Zigbee2MQTT with as little boilerplate as possible. https://pyziggy.github.io
A new type of development environment for working with agents
https://github.com/stravu/crystal
It supports Claude Code and Codex, but has you constantly working on multiple features in Git worktrees. This way you are always able to stay busy while waiting on your agents.
It has built in tools for review, such as a diff viewer, and a quick button to run your application in different worktrees for testing. It has completely transformed the way I work.
Obsetico App (named after a friends' comment that "it's great for Obsessed people like my wife"
A mobile app to track tasks, events and any info about anything you care about: your car, home, tools, workshop, appliances, pets, lab equipment... anything really.
Lets you organize "resources" in a hierarchy (like "folders"). You can then define tasks, add pictures, geolocation, contacts, notes, events, etc to them. Recently added the feature to "share" resources with others.

It's so generic that it's hard to describe :-) I need a better elevator pitch.
Still working on https://theretowhere.com, which is a website that makes it easier to find apartments and hotels/airbnbs close to people and activities you care about.
The past couple months have been fun since I've implemented a lot of new highly-requested features into the site's city heatmapping capabilities. One thing I've found motivating is having my own private changelog that shows screenshots of feature requests people have given me, and then dates for when I finally finished those features.
It's easy to forget how much stuff you've built in a month or two, sometimes.
I joined two current interests, my need to learn better JavaScript (since I never used it much) and the discovery of programs like PICO-8. I realize TIC-80 is basically the same but allows me to use other languages, so I’m trying to write small games using JS. I’m still on the struggle phase, trying to learn how to make sound effects, music etc. but I like the fact it comes with everything you need to create whatever you want. Also like how it makes you forget about all the giant software complexity nowadays.
I am working on Octelium https://github.com/octelium/octelium a FOSS unified zero trust secure access platform that is flexible enough to operate as a modern zero-config remote access VPN, a Zero Trust Network Access (ZTNA)/BeyondCorp platform, an API/AI/LLM gateway, an infrastructure for MCP gateways and agentic AI architectures/meshes, a PaaS-like platform, ngrok alternative, and even as a homelab infrastructure. It is basically a unified, generic, Kubernetes-like, zero trust architecture (ZTA) for secure access and deployment, that can operate in many human-to-workload, workload-to-workload, and hybrid environments.
I actually did a SHOW HN exactly 3 months ago and received lots of invaluable critique regarding how dense, overwhelming and unreadable the docs and repo README were. I've actually spent a lot of time trying to improve the quality of the docs and README since then. I'd love to receive any feedback, negative included, regarding the current overall quality of the docs and README from whoever is interest in that space.
Can you communicate the value of Octelium in 25 words or less?

WithAudio a one-time payment, desktop text-to-speech app that helps users read better by highlighting text as it's spoken.
Current Challenges:
Technical: It's difficult to consistently parse text from various document formats. The I also wants to expand to more platforms but I know I need to focus on marketing.
Non-technical: The product has seen some success with minimal marketing, but I keep getting distracted by spending too much time on technical work. I know I need to do more for marketing but I keep going to my safe space (my IDE).
I believe in the product but it keeps reminding me how difficult is to get somethig to a polished, finished state for all users. 90% of the project takes 90% of the time and the other 10% takes another 90% of the time.
Appreciate any feedback.

I'm working on a video platform called Nickel. 5-second clips and 5-minute (max) videos. I've been slacking on development but realized recently that I lack focus and am easily distracted by other projects. I wrote about this yesterday.
https://blog.webb.page/2025-09-28-ikigai.txt
I did figure out something I've long wondered about recently. Y'know how you can see previews of videos in Messages? I got it working! Here's an example video: https://nickel.video/6NI3n_IlIlII
My inspiration for Nickel was 1) missing Vine and 2) not wanting to use YouTube to share my gaming clips.
MAXSTACK: Web framework for rapidly building SaaS apps with AI - trying to enable the next wave of 'fast-fashion saas'. Think of it like better-auth is doing for auth, I want to do for the rest of SaaS
- comes with common SaaS features pre-built (crud, blog, auth, etc.) - import templates from the framework until you want to customize them - create forms with just a zod schema - good docs, typescript interfaces, a CLI for common tasks, and MCP for your AI agent
If you're building something now or want to - I'd love to help. Could use the experience to make things easier through my framework.
In my free time I’m still working on My Financé (I keep getting feedback this name is confusing), which is a fairly undifferentiated personal finance tool.
It’s a labor of love, but I love it!
I’m currently building a simulation engine that lets you forecast your spending, build scenarios (like taking a year off, getting a cat, move to a new city, etc based on your current spending patterns and assets.
https://myfinancereport.com/
It’s great fun to have a project of one’s own to just toil away on.
I don't know what it is about this name, but I read it as "My Fiancé". My brain did not register the first "n" and it wasn't until I read your parenthetical remark that I went back and re-read.
The name isn't confusing, per se ("get married to/be exclusive with your finances", OK), but it also isn't very strong... "financé" is also very strange and awkward to pronounce as a native English speaker. Probably because it comes across more as Spanish-seeming despite it being a play on a French work.
Yeah it was meant to be along the lines of:
My Financé, because you should love your finances.
To your point, I think it’s hard to notice the spelling, and hard to figure out how to pronounce it.
It also is the same spelling as My Finance, which is tricky to rank for on Google.
Overall, it seems like it has potential to be a fun brand, but the constant confusion has led me to strongly consider a “rebrand”.
> I don't know what it is about this name, but I read it as...
same misreading

Earth Meta Insights
Since a few months back I am working on a side project to give a snapshot of the regional and global species and natural ecosystems.
I use manual (me) and automated tools (web and literature search tools, llms, visualizers ...) to search, extract, organize and visualize ecosystem literature and data.
A regional example of mountain gorilla's of Rwanda: https://www.earthmetainsights.com/emi-cards-gorillas-of-rwan...
A global example of Elephants across the world: https://www.earthmetainsights.com/emi-cards-state-of-elephan...
If there are some species that are you would like to see a snapshot of, and the region/location let me know and i will try to get a similar visualization. DM or as reply to the chat. Share the species name (common or scientific) and location (can be a city, town, region, province, country).
It is a work 8n progress, but I would be very happy to recieve feedback.
I appreciate what you're doing here. I think it's really important to have this kind of high level overview of these species. I have a little feedback based on clicking around the site.
When you click on a country in the map view(under Elephants, for example), I think the map still has focus instead of the card. So this means you can't highlight text, click on links, etc within the card. Also if you scroll using the scroll wheel, you end up zooming in and out on the map.
I wonder if it would be good to have a "see more" link or some such here, so you can view the same information in the card, but on its own discrete page for each country?
Really appreciate that you checked out the website. It is a bit hacky, but for now i am happy with it. Indeed that is correct, the focus is on the map. I am going to fix that. Thank you.
As for the see more, it is in my planning. I can do it manually, but I am waiting for some free time to automated that.

Emilia, a personal relationship manager. Every once in a while I meet extended family (wives of cousins or their children) or I meet a fellow soccer parent and I forget their names, or who's related to who.
I've used Monica HQ to keep track of this but thought I could tackle differently using AI. With AI you could ask questions like "who's everybody on my aunt's side? Like cousins and their family" and get a good answer.
Afaik other "relationship managers" out there are professionally oriented, for sales people. A lot of them talk about LinkedIn integration, for example.

I'm working on a product to break down information siloes for private market investors. A lot of data for private equity, private credit, and venture capital firms lives in memos, deal books, conversation notes, emails, and chats. In some cases, attempts to organize that data in a more structured format (e.g. using the CRM) has resulted in data not getting recorded because of the friction of managing those types of systems.
So basically, I'm building a system where users can query all of that unstructured data and add more with a little less friction.
Working on Fraim, open-source agents for cloudsec and appsec engineers to complement existing deterministic scanners. Born out of our 3 years of learnings building such scanners for IaC. Turns out in the real world policies are subjective enough to make this hard.
Examples:
- Policies are frequently subjective. Hard to codify, but LLMs can evaluate them more like a security engineer would. "IAM policies should use least privilege." What is "least" enough? "Admin ports shouldn't be exposed to the Internet." What's an admin port?
- Security engineers are stretched thin. LLMs can watch PRs for potentially risky changes that need closer human review. "PR loosens authz/authn." "PR changes network perimeter configuration."
- Traditional check runs (SAST, IaC, etc.) flood PRs with findings. Security doesn't have time to review them all. Devs tends to ignore them. Frequent false positives. LLMs can draw attention to the important ones. "If the findings are unusual for this repo, require the author to acknowledge the risk before merging."

Super interesting!
I'm building Mighty, a library that lets you render Astro components everywhere.
https://go-mighty.vercel.app/
(Will probably register a proper domain name close to release)
Historically, Astro hasn't had an API like renderToString for React/Vue/etc. that takes a component and renders it on the server. That changed with the release of the Container API last year: https://docs.astro.build/en/reference/container-reference/
But there are still a lot of rough edges:
- Importing components is a hassle (you have to go dig through the Astro manifest or create a TS file that exports all your components)
- No Vite integration (so no local dev support, or hot reload)
- No styling support (this is probably the biggest one)
Mighty will provide dev + styling support and a simple way to import your Astro components, with adapters for Hono and Laravel when first releasing. For Hono, it should be as simple as writing a few lines of code:
https://go-mighty.vercel.app/guides/backend-adapters/hono/#r...
Still WIP, but I hope to have something out by the end of the year! Let me know what you think.

Thinking about vibe coding a Behaviour Change App as opposed to a simple habit tracking app. I have personally used the habit tracking apps, and they are absolutely useless. My app will help the users learn how to actually change their behaviour, teaching them micro skills like value alignment, self-compassion, etc. These micro skills will help them in all aspects of their life and mainly to change bad habits.
I’ve been working on https://fontofweb.com, a search engine for real-world web design.
Most design inspiration sites lean heavily on curated mockups (Dribbble) or award-winning showcases (Awwwards, Mobbin). That makes them polished, but they don’t reflect what most production sites actually look like. Font of Web takes a different approach: it sources directly from live websites, and the community can clip specific elements instead of entire pages. That means you can browse navbars, pricing cards, dashboards, etc., not just full screenshots.
Each clip is enriched with metadata (fonts, color palettes, original domain). Search works across that metadata, natural language queries (“minimalist fintech dashboard”), and even visual similarity — so you can find results either by text or by image.
There’s also a Chrome extension to snip and save from any site.
I’d like to hear from designers and frontend engineers: is this useful in your workflow? Anything obviously missing?
I'm working to build a tool for macOS and Windows desktops to help non-technical users figure out what's wrong with their home internet and how to fix it. https://www.networkweather.com/
It's literally just me in the garage right now banging out prototypes, talking to MSPs, and probing networks/WiFi/OS to make this tool.
The hope is that companies care whether employees are productive when remote/hybrid/on-the-road, or at least are sick of trying to triage first line helpdesk tickets about home network issues and Zoom glitches.
Trying to document my current hobby project, but stuck in the analysis phase. I dont even know what it is. When I try to describe its purpose I get blank looks. People tend to need physical demonstrations to understand whats going on. Its not entirely new, or novel, its definitely not revolutionary, but it is a hybrid of so many things, in a very indirect sense, that its just beyond my verbiage. Not a humble brag, I dont think its amazing or anything. I have just failed to describe it. Have been trying to get a phd I know to look at it, and describe it for me, but he just straight up isnt interested.
Er... is it software? Hardware?
Has both. Hardware is mostly in the prototype phase.

Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].
Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.
I hope to sell them and then probably never recoup my investment.

I'm working on a notes app that is as simple as Apple notes, but has native markdown support and uses semantic search.
Uses SwiftUI for the UI, and Zig does most of the heavy lifting on the backend. It's inspired by ghostty which uses a similar setup[1].
Right now it only works for Mac, but I'll be porting to iOS as soon as I get the markdown renderer polished. It's not available to the public yet, but I'm using it as my daily driver and hope to release it later this year. I've open sourced it so you can see the source code here[2].

A burnout detector for SREs. The goal is to help teams identify incident responders who may be overworked/getting burned out.
We are looking at:
-Objective data: signals from incident management tools (Rootly/PagerDuty), GitHub, and Slack
-Self-reported data: asking the engineers how they feel via short survey
From this, we generate a CBI score (Copenhagen Burnout Inventory). We're still in beta, but we've received positive feedback from our beta testers, especially from manager of large and distributed orgs.
It's fully open-source, you can test it out locally https://github.com/Rootly-AI-Labs/rootly-burnout-detector-we...
Alternatively, we offer a hosted version with mock data, allowing you to play with it. https://www.oncallburnout.com/
If you have any feedback or ideas, shoot them my way :)
Very good idea. I could have used this multiple times in my career. I am a go until I drop type of person, and I'd just keep going.
Currently bootstrapping a SaaS side project: https://diplomium.com
Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation.
The bigger picture: Certificates are often the only tangible outcome of a learning experience. By making them verifiable, permanent, and easy to distribute, organizations save admin time while learners get a trustworthy credential.
Status: Running for 2 years, used by schools and training centers in Latin America. Now building AI-powered features for design editing and data extraction from PDFs.

Banker (banker.so): An AI spreadsheet that excels at spreadsheet understanding (pun intended).
There are some AI spreadsheet products out there mostly as plugins along with MS Copilot. However my experience with them showed that they are bad at understanding spreadsheets.
The reason is that sheets are 2D data models. Because LLMs are trained on 1D data models (simply text), translation of 2D data models to formats an LLM can consume is a big context engineering task.
I read and implemented some of the algos mentioned in SpreadsheetLLM paper released by Microsoft. Ironic, isn't it?
Got it to a nice working state. Give it a go - if you need more tokens, let me know!
I’m still working on Simple Observability:
https://simpleobservability.com
I built it because I needed two things:
- A super easy-to-install monitoring tool that doesn’t require bash scripts or config files
- A mobile-friendly, UX-first interface where I can check everything from my phone
It’s now pretty feature complete. I can see a full picture of all the servers and VPS I run straight from my phone.
Setup is one command, no config files, and everything else happens in the UI. There’s a catalog of predefined alert rules, and creating new ones is easier than anything else I’ve used.
There’s a free tier if anyone wants to try it!
Very cool! However I couldn't get the agent running on an ARM based Oracle Linux Server 10 in OCI. I tried two different servers
level=ERROR msg="failed to fetch collection config. retrying in 5s..." error="GET /configs/ failed with status: 204"
I've been working on LogChef (https://logchef.app) - a specialized log analytics UI for ClickHouse that focuses on powerful querying and exploration without the complexity of full observability platforms.
The core idea is to leverage ClickHouse's incredible columnar performance for log analytics while providing a schema-agnostic interface that works with any log table structure. It supports both simple search syntax for quick queries and full ClickHouse SQL for complex analytics. Also it has proper RBAC: Team-based access controls for multi-tenant environments.
Off late I have also added some AI features:
It's open source (AGPLv3) and deliberately doesn't handle log collection - instead it integrates with existing tools like Vector, Fluentd, or OpenTelemetry Collector. The roadmap includes REST APIs, client libraries, visualizations, and alerting.Built with Go + Vue.js + TypeScript. Currently handles millions of log entries daily in production environments at my org. The deployment is just a single binary deployment with a SQLite DB.
Would love feedback from the community! GitHub: https://github.com/mr-karan/logchef
I'm working on Matry - it's a tool for designing in the browser. It's kind of like a cross between Webflow, Vim, Storybook, and Cursor. I'm trying to strike a fine balance that I don't see in existing tools.

Also, any suggestions for blogs that could be added as sources is appreciated.
Looks cool. I would be honored if you added my blog. Each post is a summary of a recent computer science research paper.
https://danglingpointers.substack.com/
Also, maybe add a place on your website where people could submit blogs for your consideration? I didn't see one at first glance.
Hi Blake,
Yes, the form to submit blogs is one of those last-mile polish that I need to work on.
I've added your blog as a source. Very cool concept.
An editor for creating custom accessible color palettes for web/UI design. :)
https://www.inclusivecolors.com/
It gives you precise control over every shade/tint (no AI or auto generation!) so you can incorporate your own brand colors, and helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) against all grade 50 colors, such as red-600 vs gray-50, or green-600 vs gray-50.

I’m building an ETL tool that “just works” and gets out of the way. I can write shell scripts and python to do this stuff but honestly I just want to drop my files/API results into a GUI tool and have it combine things for me. Landing page is at https://eetle.com
Building https://multi.dev, an AI coding agent with bunch of FOSS contributors
We took a great amount of learning from tools like Cline, Roo.. After spending some time on their tech as active users/devs, we decided to build multi from scratch with drastically different take on core features, tech stack, ux/devex..
If you are an active user of similar tools, and/or want to try multi.. We want to hear from you.
-- edit: I am one of the core contributors to multi. And we are in the process of open sourcing it.
What's the difference? Tell me more.
I'm working on a site for filmmakers to help showcase themselves!
Why? >
LinkedIn isn't for creatives. Actor's Access is dated and charges a ton for basic extras Squarespace/wix is fine but everyone in 'the biz' has one and nobody wants to maintain it. Plus they're all silo'd.
Check out my site if you wanna. You get to host your own headshots, resume, and reels. You can upload your screenplay there and hear it read outloud. You can put up your cinematic scores and make a place to send people to hear your music.
https://cinesignal.com
Looking for users who wanna test the system out. Give me a shout and I'll throw you some credits if you wanna hear your screenplay read outloud.
I'm working on a WordPress PaaS with dedicated lanes for bots. The status quo around WordPress is that you block bots using Cloudflare, else your site crashes. Since AI search is here to stay, we need a way to let bots crawl WordPress sites without crashing the server.
Currently at MVP stage, no domain yet.
Regular Cloudflare + heavy caching should solve all crawling problems, no?
For most bot visits, there should not be a single database request.
https://github.com/hsnice16/forming-jotform
I already have a similar project for Typeform, for which someone reached out to me to see if I can help them integrate it into their project.
This project is very similar to that, but it implements Jotform.
I'm trying to get my agentic software specification tool Arbiter to release (UI polish/debugging is so slow :/, browser shenanigans are harder than Rust fr). It's basically a tool that AI agents can use to construct a project specification. The twist to Arbiter is that the specs are structured and validated, and you can compile them to get:
Services with stubbed endpoints, UIs with placeholder components, Dockerfiles/Terraform/K8s infra, E2E tests (via declared flows), Github/Gitlab epics/issues/subissues
It's also got github/gitlab webhook integration, so you can do stuff like trigger agents reactively when events occur on a repo, it includes cloudflare tunnel support so you can set up webhooks even in a local dev environment, and the project generator is fully customizable.
How does it work? is just a documentation specification like spec kit?
Nope, it's a structured spec agents construct using a CLI or MCP (you can also interact with the spec using a web UI). It's CUE, and validated against a schema. Instead of taking your conversation and generating a markdown document that agents might (but often don't) respect, the agent populates the spec in the service from your conversation, then when you're done you can use the CLI to automatically generate a bunch of code.
Codexes Factory: algorithmic tools to create, operate, distribute, and market entire publishing imprints. This week I am launching my first imprint, Xynapse Traces, with 66 books in the Korean pilsa (筆寫) style. Later in October, Nimble Ultra, devoted to the history and practice of intelligence and espionage. Last week I built a giant collection of 575 imprints that are a shadow superset of the ~540 imprints operated by the Big Five publishing houses (Penguin Random House, the largest has ~300). Teeny weeny tip of the iceberg at NimbleBooks.com.
I'm working on a new CAPTCHA designed to be very simple and user-friendly for humans, while maintaining strong LLM bot protection. I'm currently looking for pilot users (content creators, site owners, or anyone interested) to test it out and provide feedback. If you're interested, please comment.
An “everything” feed reader. Its a plugable framework that allows you to push anything into an RSS feed reader type interface. Email, Slack notifications, RSS, etc.
I want one place to manage ALL notification settings. So if I want to be notified of Slack messages that contain the word “cat”, I can do that.
I am also looking to add summarization and tagging using a local SLM. Trying to find a method that can run on older hardware.
I'm building with python/fastapi, react/tailwind/vite, with Claude Code and using test-driven development.
Red-green-refactor is tedious for humans but perfect for AI. And the test names & code make great documentation of every micro decision, running in milliseconds to prevent regressions.
The software itself helps people perform construction approvals.
Old way: dozens of documents and versions sent back and forth over email. Many fiddly details that must be checked - to streamline the process we'll use AI to provide verdicts that help humans make decisions.
I plan to create content & teach what I've learned.
https://approviq.com
Trying to figure out how I can make agentic development better with: https://toolkami.com
The space is moving so fast, so I had to note down my thoughts e.g. https://blog.toolkami.com/openai-codex-tools/and figure out what's next.
Picshift.io: upload an image, get a URL, change what shows at that URL whenever you want. Works anywhere an image link works.
You can randomize and schedule images to show up at the link as well. Super useful for marketing, maintaining screenshots on a website or in documentation, etc.
Would love to hear if anyone wants to use it!

I am all-in on a Unity game right now. Working with one other person and hoping to ship to Steam later this year.
Thinking about play testing at scale is a new thing for me. I've been getting into visualization techniques like using 3d textures to build voxel heat maps in-editor. We've managed to accumulate quite a bit of play testing telemetry already. The power of aggregated statistics in the editor views is absolutely mind-blowing to me. For level designers it's like having proper omniscience. Being able to see things like thousands of samples (manifesting as a bright red voxel) that wound up tripping over the same misplaced geometry is like cheating.

vulnerability discovery and exploitation, with zero false positives.
https://vyprsec.ai/
Yep, you read it right. 0 false positives. We scan the whole codebase for possible vulnerabilities, rank them, write the proof-of-concept for exploitation, spin up the software in a sandbox, and then attack. All of them happen autonomously without human involvement.
The end report? Only verified vulnerabilities are being reported without noise.
Already reported some unknown vulnerabilities in open source projects. The good thing is we're just getting started.
Improving my 'Video game generator from photos'. The bottleneck of this kind of generator is 'how much time to obtain the video game". I managed on my last vacation (it's a side project) to reduced it to 2 hours. This is an example of one FPS made by my tool : https://free-visit.net/fr/demo01

I’m working on Colanode, which is built to close the gap between the convenience of cloud tools and the ownership of local software. It brings chat, docs, databases, and files into one open-source, self-hostable workspace where data lives on your devices first and syncs in the background. Unlike typical SaaS tools, Colanode is local-first: everything works instantly and offline, infrastructure stays minimal, and you keep full control of your data.

How is this different than using Google docs or something ?
Scriptwriting require specific formatting (set by Hollywood ages ago). Doing this in google docs is really painful. Besides that, people who work in this industry are already used to the format, so if you wanna pitch something to studios, they expect to be in industry format.

This is mostly a nostalgia play--I'm pining for a time when app development was much easier. I'm trying to apply lessons from early Rapid Application Development while still providing a full-featured language.
I confess that I haven't gotten any traction at all, but I find it incredibly useful for my own consulting business, so I'm going to keep on working on it.
I’m at a crossroads with my Speed Cubing Competitions listing app (SCComps.com). It’s an iOS app built in Flutter, has around 250 downloads, and currently generates no revenue. I'm spending about $500 a year just to keep it running. There’s little community engagement, and I'm debating whether to double down and rebuild it in Swift—or just shut it down altogether.
pptx-tools, a collection of cli tools for interacting with Powerpoint presentations. Covers use cases that PowerPoint doesn't support. Currently in the making:
* pptx-grep - find text across multiple powerpoints, yield file/slide no and text excerpt of match
* pptx-dump - dumps extended info about a powerpoint, such as number of slides, applied master slides, used fonts etc.
* pptx-lint - allows to define validation rules for pptx based on content and/or formatting. E.g. presentation must not contain word "TBD", all text must be formatted in Arial etc.
Trying to build a secure, configurable and easy to use authentication system (relative to my understanding)
I have experienced knowledge gaps and blind spots that I am attempting to fix. For example most users worry about security of hashed passwords and yet they do not realize that the TOTP (eg Google Authenticator) use symmetric encryption and quite a lot of the authentication providers store the private key in plain text in their database. List goes on...
I’m working on yet another cloud based coding agent https://seniordev.io/ that connects to an existing GitHub repo, spins up a feature branch, commits incremental changes, and opens a PR. You can jump into an embedded VS Code server to review and tweak the code before merging—no local setup needed. Any feedback is greatly appreciated Thanks!
Currently I've been working on https://terragonlabs.com which is a way to orchestrate Claude Code and other agents (Amp, Codex) as background agents.

A script which will find random pictures of anyone in the family from the Immich database, resize them and add metadata on them like where they were taken and when and put them on the TV to show as kind of a screen saver when we're at home.

- some service worker hacks to do seamless image processing (jpg/png -> webp), storage and retrieval
- document snapshot history, thumbnail preview with iframe and snapdom: html->img sorcery
- live previews and compilations
- loads very quickly, navigation and cold starts, images make heavy use of the Cache api
- use in-browser git (thanks isomorphic-git) for version control; optionally sync with github via cors proxy (host your own if you want)
- best of all completely free to use. 99.5% finished MIT github repo dropping soon ;)

- the coolest feature (imo) is a "reader": upload Japanese texts (light novels, children's books, etc), then translate them to your native language to practice your reading comprehension. Select text anywhere on the page (with your cursor) to instantly do a dictionary lookup. A LLM evaluates your translation accuracy (0..100%) and suggests other possible interpretations.

That's pretty cool. It's nice to see this exists.
For me, I'll probably send an email later to support to ask (no rush, since it's out of stock anyway), but I was checking for info on compatibility with Yamaha (e.g. my Cross Connect) ebikes. It's not on the compatibility list. They make their own (mid-drive) motors (PW-SE on mine I think) and proprietary batteries. They pulled out of the United States market altogether so getting more batteries from them again is doubtful. (Mine currently charges to ~85% and then throws an error code, but it still works for now.)

A tool for Muslims. Dreamstate: Interpret your dreams Islamically
https://dreamstateai.replit.app/
Traditional Knowledge: Constrained to Ibn Seerin's classical teachings — trusted by Muslims for over 1,000 years AI-Powered Analysis: Unlock the meaning of your dream with 4,300 dream symbols from the Dictionary of Dreams.
Share your dream confidentially, answer a few context questions, and receive your authentic Islamic interpretation in under a minute.
This is an MVP which I started <4 weeks ago. Currently validating Desirability, Feasibility, and Viability.
Confidentiality is very difficult to guarantee. You may want to put some brackets on what your users can realistically expect and give them tips on how they can stay anonymous. But lovely and novel idea, really neat to see these kind of cross-overs.
On the app's dream input page, it specifies a bit more "Your dreams are private and not stored or collected." - would that cover it? Thanks for your feedback and encouragement!
That is a 'pinky promise', it may well be true and let's assume you are well intentioned but it leaves the door open to you not being trustworthy after all or someone intercepting the data while it is being processed (for instance, by compromising your service).
In order for you to process the dream data you have to at least make a temporary copy. One way to get rid of that is to move the interpretation part to the client side if possible. Another thing you could do is if people are really concerned about the content of a particular dream to suggest they use TOR or some other anonymization (not perfect, I know) service to at least hide their internet location from you, the operator of the service.
Does the app itself run entirely within your own infrastructure or does it call out for part of the work?
definitely WIP but my and my brother are working on sourcing and selling microplastic free athletic wear. Shopify is super wip https://tryfibre.com/

Kind of have been wasting time with Cloudflare workers engine. Trying to build a system that schedules these workers for a lightweight alternative to GitHub actions. If you are interested in WASM feel free to reach out. Looking to connect with other developers working on the WASM space.

Oh hey I can post an update. My little electronic dictionary is finished. Software works and it's all dressed up in a stealth notebook case. (It runs Python now instead of Lisp though)

I've been wondering for years if historical magazines/periodicals could ever be transformed into a modern ebook format. PDF doesn't cut it, but most other efforts are unsatisfactory... part of what makes a magazine a magazine is the rich, mixed content. So, for the past few weeks (months?) I've been taking a stab at it with the science fiction pulps. Started with Analog/Astounding, and I was able to re-typeset the cover (with original art), most of the interior, many of the ads, and so on.

I still need to put together a build system to actually zip this up into an epub file...
just bought the milliondollargpt.com and have no idea what to do with it...
For now, I think it would be funny if you put plaintext that says "just bought the milliondollargpt.com and have no idea what to do with it...". Optionally as a hyperlink to your comment I am replying to.
Edit: Spelling
done! thanks
thats make sense! just a sec :D
I'm writing a programming language for feature-flags/remote-config. I figure a simple DSL has to be an improvement over YAML or a series of forms in a web app.
I'm also generally disappointed by the lack of testing that's performed on feature-flag definitions. So I'd like to have a test runner capable of asserting your feature flag's rules matches your intent.
I have been prototyping a local-only social media manager initially targeting the game development community. I am sick of all the subscription only platforms such as buffer, hootsuite etc.
Initially I have been looking at Mastodon and Bluesky since they have sane APIs.
The plan is to make it so that you can sync your data folder either manually (e.g. dropbox, or sneakernet if you want) or a via a basic cheap data plan.

I've been building an innovative guided munition for Ukraine for the last 4 months, we have first prototypes made and have arrangements with the testing range to begin flying them soon.
Mostly decentralized/federated crypto stuff.
1. COCKTAIL-DKG - A distributed key generation protocol for FROST, based on ChillDKG (but generalized to more elliptic curve groups) -- https://github.com/C2SP/C2SP/issues/159
2. FREEON (Threshold signing tool for open source development teams) -- https://github.com/soatok/freeon
3. A reference implementation for the specification I wrote last year for federated Key Transparency, so that the Fediverse can build end-to-end encryption (E2EE) with stronger, less-centralized notion of trust than TOFU -- https://github.com/fedi-e2ee/public-key-directory-specificat...
I wrote a blog post about a lot of this work (and my other side projects): https://soatok.blog/2025/08/27/its-a-cold-day-in-developer-h...
And for the overall ActivityPub E2EE work: https://soatok.blog/category/technology/open-source/fedivers...
A kanji learning app using free dictionary data and the FSRS spaced repetition system for maximum context per card and optimal memory retention.

My theory of learning is that you learn the characters better if you learn how to read and write them at the same time. And flash cards are better by giving you as much information as possible about the character.
This is fundamentally different from e.g. WaniKani which only teaches you how to read the character and relies on pre-made mnemonics (plus SRS) for easier retention, and from Anki which (normally) has very minimal flash cards, showing only small bits of information per card. When you have the whole dictionary on each card it gives you the opportunity to create the easiest connection with what you already know. This may be some made up story about the components (radicals) in the kanji (like WaniKani does) a word you already know, other kanji sharing the components, etc. The more connections you make the easier it is to learn them.
One of the features I personally use extensively is the ability to bookmark words containing the kanji, which will then pop up at the top of the words section in a later review. If I remember the meaning and the reading of the words I have bookmarked for this character during a reading review, I consider mark card as good. If I remember none of them I mark it “again”.

I think this is a really cool idea! I will say that I only used one search but the results seemed only vaguely accurate.
Still focused on metal 3D printer slicer software with Blender geometry nodes, and a microscopic positioning stage design for hobbyists.
On the weekend built a lattice-filter test jig with the LiteVNA64, so sorting though the pile of crystals is less time intensive.
Other hobbies maybe 3 other people would find amusing. =3

Yet another online cycling calculator, this time with an emphasis on power/speed difference between different tires.
I'm sick and tired of audiophile level bs floating around online forums and I want to create a simple tool for people to fiddle around with different settings to see what really impacts their speed while cycling.
As usual - no plans for monetization whatsoever. Nothing fancy either, just an elaborated weekend project.
If you like the idea and want to help with graphic design and or html just let me know. :)
Yet another browser-based screen/video recorder and editor but with multiple inputs, full privacy and scriptable effects - a slow weekend project
For the past ten months I've been working on a way to transmit and receive around 10 kilobytes halfway across town. I've blown through government grants totaling in the hundreds of millions of dollars but it seems this is an unsolvable problem.
Ha ha ha. Funny joke it seems
Esperanto havas la mal- prefikso por krei specialcelan antonomion, sed la rezulto ofte mankas klarecon, kaj kiel morfemo mal mem estas morale kondamna: komparu malica, maligna, malversacio kie mal ne estas sinkrone disigebla.
Tial mi vorkas por krei liston de ĉiuj mal- vortoj kun sen mal- alternativoj. Fakte ĝi ankaŭ povas servi la kontraŭan celon, provizi pli ĝeneralajn mal- vortojn kiam oni deziras krei verkon pli facile akirebla de ĉia nivelo.
Mi planas eldoni ĝin denove ĉe https://eo.wiktionary.org/wiki/Aldono:Pri_antonimoj kiam mi finis, sed nun estas pli facila progresi per citilaj kaj vidŝangaj kromaĵoj ja provizata ĉe https://fr.wikiversity.org/w/index.php?title=Utilisateur:Psy...
