At the moment, the flow goes like this:
1. During the week, write posts for things that have happened.
2. Posts can be assigned to groups. (family, friends etc).
3. At the end of the week (or month), the app automatically creates a newsletter for each group by pulling posts assigned to each group. Add some final touches yourself and send it off!
4. Every newsletter will come with a link to download all images.
I'm trying to design it to be as old people friendly as possible which meant making the experience as simple as it can get. This made me settle on email newsletters. Emails are ubiquitous, have been around and will be around for a while. It's easy to sign up and things are just pushed to you instead of having to go to another app.
Another thing I want is multilingual support as my family is Korean my in-laws are not.
I'm hoping to get an MVP working this week and get some testing done with my own parents and in-laws.

- Nuclear Reactor Starter Kit --- an open source set of procedures, processes, templates, and maybe even some IT advice that should help newcomers start companies with nuclear quality assurance programs easily and quickly while also making a new format in which nuclear companies can share lessons learned in efficiency.
- Reactor Database --- similar to the iaeas PRIS but focused on reactor development rather than power reactors. Will include nuclear startup company tracking with details gleaned from statements and maybe extrapolated where necessary from simple simulations. Will include things like fuel cost and licensing progress. This way people can more easily separate vaporware from real nuclear, and keep track of promises vs delivery.

I have tens of thousands of ads in the collection and it would take me many lifetimes to complete, but I've been using AI to extract and catalog the meta data. I can get through about 100 ads/day this way.

It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood.
Visually it looks the same. The suggested videos come from predefined buckets on topics they love.
E.g. 33% fun math, 33% DIY engineering, 33% creative activities.
Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with Minecraft in it, never gets surfaced.
For anyone interested in using it, send me an email.
I'll put you on my list. And you can contribute ideas to our community Google Doc.

A game engine that lets you code multiplayer games without coding the multiplayer! My idea was to put multiplayer into the fabric of the programming language itself. This allows the engine to automatically turn your game into a multiplayer game, without you needing to learn anything about networking or synchronization. I imagine there are lots of people who have the talent and creativity to create a multiplayer game but don't have the interest or patience in learning how to code multiplayer, and so that's who this is for!
I've been working on this for 3 years and there were lots of tricky parts rolling back and deterministically executing a whole programming language, but it's working now! My next phase is to increase the breadth of features so better games can be made with it!

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.

So I thought: what if, when you opened the PR, you had a tool that actually executed your migrations, saw what locks they acquired (in runtime) and then reported it as a comment to your PR? This would provide you with yet another data point you could use to reason about whether your migration is safe to deploy or not. For example:
ALTER TABLE users ADD COLUMN email TEXT:
acquired AccessExclusiveLock on relation `users`
It does this by opening a transaction, executing the statement, and observing the `pg_locks` view from _a different_ connection before the initial transaction is rolled bac (or committed, depending in the flags you passed). The idea is to be able to use it as a CLI, as a library or with a ready-made GitHub Action (which will take care of commenting in your PR).It's in early-stage and very much a PoC yet, but I think there's merit in the idea.

In the app you pick a folder with videos in it and it stores the path, metadata, extracts frames as images, uses a local whisper model to transcribe the audio into subtitles, then sends a selection of the snapshots and the subtitles to an LLM to be summarised. The LLM sends back an XML document with a bunch of details about the video, including a title, detailed summary and information on objects, text, people, animals, locations, distinct moments etc. Some of these are also timestamped and most have relationships (i.e this object belongs to this location, this text was on this object etc). I store all that in a local SQLLite database and then do another LLM call with this summary asking for categories and tags, then store them in the DB against each video. The App UI is essentially tags you can click to narrow down returned videos.
I plan on adding a natural language search (Maybe RAG -- need to look into the latest best way), have half added Projects so I can group videos after finding the ones I want, and have a bunch of other ideas for this too. I've been programming this with some early help from Aider and Claude Sonnet. It's getting a bit complex now, so I do the majority of code changes, though the AI has done a fair bit. It's been heaps of fun, and I'm using it now in "production" (haha - on my PC)

It’s the biggest and dirtiest dataset I’ve ever worked with, so it’s been interesting to figure out practical solutions to run things fast and generalize cleaning tasks. Of course it’ll be impossible to get every case (I can only match about half of the state licenses to national records at the moment), so I’ll have to figure out a user-edit/consensus system for the rest.

Decided to do an extended sabbatical after being part of one of the many tech layoffs the last years, and I'm thus working on things I like, instead of things that pay..
Collecting and cataloging craft beer venues from around the world, at https://wheretodrink.beer Still a WIP, and it's not trying to be the most extensive list, but I want it to be a substantial list. Once I reach a certain maturity in the data I'll probably look to spawn minor projects off from the data set.. have a couple ideas already that I'll just keep to my self for now :D
I also had a set of left over domains relating to beer that I'm offering up for use with BlueSky handles, and beer related link pages at https://drnk.beer - a bit on the back burner.

The idea is to improve the tooling to work with grammars, for example generating railroad diagrams, source, stats, state machines, traces, ...
On both of then select one grammar from "Examples" then click "Parse" to see a parse tree or ast for the content in "Input source", then edit the grammar/input to test new ideas.
There is also https://mingodad.github.io/plgh/json2ebnf.html to generate EBNF for railroad diagram generation form tree-sitter grammars.
Any feedback, contribution is welcome !

I analyzed 7 years of Armorgames.com data (999 games) to understand web gaming market trends.
Key findings that might interest fellow developers:
User standards are rising: Average ratings dropped from 7.02 (2018) to 6.45 (2025), but the percentage of high-quality games (8.5+ rating) actually increased from 12.3% to 14.7%. This suggests quality polarization rather than overall decline.
Genre trends: Rising: Idle games, Strategy, RPGs (deeper gameplay mechanics) Declining: Traditional arcade/action games Stable: Puzzle and Adventure (web gaming staples)
Innovation wins: The highest-rated "hidden gems" all had one thing in common - innovative mechanics rather than genre variations. Games like "Detective Bass: Fish Out of Water" (9.3 rating) and "SYNTAXIA" (9.1 rating) show originality still pays off.
Market maturation: The correlation between rating and popularity is surprisingly weak (0.126), suggesting quality ≠ virality. However, play count strongly correlates with favorites (0.712).

I had fun with the interface - it's themeable, and inspired by classic cameras: lets you quickly switch between full auto/half auto/full manual modes with dedicated dials.
Going to add more features in the coming months, but the #1 focus is keeping it super simple and blazing fast.
Given that virtually all processing pipelines these days stack multiple shots to create a photo, as far as I'm aware this is the only way of getting a "traditional" single-exposure photo on iPhone, where the shutter speed is actually meaningful.
There are other camera apps that support Bayer RAW capture, but those support a bunch of other formats, and you probably don't want Bayer RAW for most of your shots anyways, so for my own workflow it's better to have a dedicated app that I can launch really quickly rather than tap around in menus.

The whole thing works pretty well, it's built using Godot & a custom Rust extension with the 6502 emulator & assembler. It can even be exported to the web so you can write your code using a CodeMirror editor and send it to the game in the browser.
Now, as expected, the hard part is making it fun. Just giving players an empty code editor and a manual for the sensors/actuators doesn't seem great, and there's also no goal for now. I'd like to take inspiration from Shenzhen I/O to build a sense of progression by tackling more and more difficult control challenges maybe?
It also supports running multiple computers at once so I think there's some fun potential for a "multiplayer" mode where you try to achieve some objective (scanning X, mining Y) against other players by sending spacecrafts with your code on them and all the crafts would run on one server. Anyway I'm curious if people would be interested in such a game!

Everything from farm related stuff (water, food, shelter, etc.) to self-sufficiency (solar, etc.) to real time monitoring (which cameras, affecting power supply).
Who knows if it'll ever happen, but just planning everything in detail is a lot of fun. Especially with weird regulatory constraints where I'm living, there's a lot to watch out for.
Example: Solar panels at >3m height need building permits. Snow in winter means panels should be set up at a specific angle. So my initial plan of putting the panels on my 2.5m high carport doesn't work. Either lower carport, lower angle, different place or getting a building permit.

So I started building something simple: a tool that lets me turn highlights into flashcards with as little friction as possible.
Just select text on your iPhone, share it with the app, and it creates a flashcard using AI — a Q&A pair and a short summary. You can browse cards in the app, or show them on your Home Screen, Lock Screen, or watchface of your Apple Watch.
This is my first iOS app, and building it has been a great learning experience. I’m using Supabase for the backend which have been mostly great.

A 3D game to help students in grades 5-8 learn Arithmentic, Fractions, Geometry, and Algebra.
50% or more of middle school students experience math anxiety, and it's no wonder that so many people grow up believing, "I'm not a math person." Math can be incredibly fun and beautiful if approached and experienced the right way. Mathbreakers is a vibrant, interactive world where all game mechanics are built on intrinsic mathematical properties, so simply by playing the game, a foundation of understanding of those concepts is built.
We're doing early prototype testing now with a planned launch in September 2025. The game engine is PlayCanvas (engine-only) and the platform is WebGL (Mac/PC/ChromeOS).

The poetry one is react native. Art and philosophy ones are swift/kotlin. I wanted to see if you could use LLMs to effectively create a cross-platform app. The idea behind react native was that you write it once in an approachable language, then the framework compiles to native app code. In 2025, the approachable language you code in is English, and the LLM now generates native app code.
It was generally a success and I feel less of a need of the development overhead of react native these days.

The idea is simple:
1. On the days I work, I get an email one hour before the end of the day (as I usually use emails as todo lists).
2. I reply to that email with what I did just like I would in a personal journal.
3. My reply gets saved and shows up on a calendar. It's nothing fancy, just the content of the email on the day it was written.
4. When I need to prepare for a performance review or a manager check-in, I can generate a clean report based on my past entries with summaries written by AI
That’s it. No login every day, no new tool to open. Just a little trace of my work, saved quietly, and summarized when needed.

An AI-trip planner with a nice twist. It shows you everything you need to know about a place even before getting there: Images, a great summary, cost of living broken down weather conditions etc. It also comes with the usual features you'll expect in a trip planning app (ai itinerary suggestions, travel expenses tracker, group chat for group trips, google places integration for looking up places to eat, things to do, healthcare places and transportation centers, and a private travel checklist). You should check it out today!

So I'm giving a try to a project which started with marketing. No implementation, just a TikTok to see if people like it. And holy crap, we got 75k views!
The new idea [2] is easier to explain (1 pushup = 1 minute of scrolling) and already has a community. Plus, not working alone helps me focus on what I'm good at: programming. I don't regret learning about other areas but doing marketing for a living is not my thing.
I'm not getting rid of SpeedBump, though. It's a fun side project and it does help people :)

I've been doing a lot of experiments evaluating LLM translation performance, and I used what I learnt (that LLMs make mistakes, but different LLMs make different mistakes, and they're better at critiquing translations than producing them) to make a hybrid translator (https://nuenki.app/translator) that beats everything else.
And I was invited to do a talk about that to a company, which was really cool! I'm 19, doing this in my gap year before uni.

Backend is already working: Boldaric https://github.com/line72/boldaric
And a simple iOS native front end (which I haven’t submitted to the App Store yet). Tor Jolan https://github.com/line72/torjolan
It has been interesting tweaking the algorithms and models for various similarity searches.
I really like that it focuses on music characteristics and not metadata, so popularity of a song/artist isn’t even taken into account. This has really helped me explore my rather large music collection especially when I get stuck in a rut of listening to the same things.

I have strong focus on db consistency and Type safety between steps.
### Built so far – core SQL orchestration (state machine, retries, observability, queue management) – strictly typed TypeScript DSL + compiler that turns flow definitions into migrations – a minimal Edge Function worker that polls, executes and reports back
### Current focus I’m heads-down on a dedicated client library. It leverages Supabase Realtime to stream events and progress of each flow run back to the browser, while having strict compile-time safety for flows defined with the TypeScript DSL.
### Next on the roadmap - Fanouts for processing arrays of data in parallel, with per-item retry logic. - SQL-based conditionals/branching that leverages JSONB containment operator and step outputs

It started as a side project to explore the latest AI trends. Now it’s something we use daily — and others are starting to as well.
Thoughtcatcher is a lightweight, AI-powered notes + reminders app that acts like a memory companion.
It helps you: - Capture raw thoughts and auto-tag them using AI - Set smart reminders triggered by context and meaning - This was a game changer for me personally - Search and chat with your notes like a conversation — not just by keywords, but by intent
Example? You’re walking out of a meeting and think: “We should revisit that pricing model after the new release.” You jot it into ThoughtCatcher — no structure, no stress. A week later, right before the next sprint planning, it reminds you. Just when you would’ve forgotten — it remembers.
What started as a learning project has grown into something useful — not just for individuals, but for teams too.
We’re now exploring B2B use cases like: • Project knowledge management • Shared team notes with smart search and chat • Meeting follow-up insights and reminders • AI-powered team memory for client or product work
Want to try it out? Android users: Download the app iOS users: Use the PWA — just “Add to Home Screen”
Still early. Still learning. But ThoughtCatcher already feels like something I wish I had years ago.
Would love your feedback or thoughts. And if you’re building something similar— let’s connect

The system is complex. Choosing the best option is difficult. Understanding the timelines, the required documents, and how to prove coverage for a visa application or school enrolment is super complex. I'm trying to streamline the whole thing.
I released phase one yesterday. It's a simple overhaul of the text advice plus a new health insurance calculator. I also paired up with a health insurance broker to give more personalised advice, since everyone needs a different recommendation.
It's here: https://allaboutberlin.com/guides/german-health-insurance
I'm now working on phase two: covering the exact process of getting insured for a visa application. I really want to walk people through the exact order of things, with detailed steps and timelines. The calculator will get a hell of a lot more complicated.
Phase three is compressing all of that. Once I have a good idea of how things work and where friction can be reduced, I'll simplify and automate as much of it as possible. It should turn a messy, complex and confusing process into a fairly straightforward thing.
I feel like no one is really doing this yet, and I'm surprised at how achievable it is.

What I have is a basic flash card app with double sided cards (for writing (i.e. drawing) the kanji, and reading). What sets it apart is that each card contains all the relevant dictionary data, and users are encourage to bookmark a couple of words to help them remember the writing or the reading of the kanji.
What I am working on now is the database backup/sync system. I store all the user’s progress in indexeddb store in their local browser. To sync I am writing a simple patch system, so they can pick a remote somewhere (e.g. a gist on github) and push their latest patches, when syncing progress I would check the hash of the patch and apply the relevant patches.
After that I am planning on turning it into a progressive web app so users can download the app onto their devises.

We used to run a content and product studio, and every time we had to get NDAs or service agreements signed, it felt ridiculous to pay $30/month for 2-3 documents.
So we built SignWith — no subscriptions, just simple pay-per-document pricing. ESIGN act and UETA Complaint.
Every month you get 3 free signatures - and then you can pay per document. So best ROI.
Works great for freelancers, early-stage founders, agency folks, or anyone who doesn’t need to send docs every day but still wants something secure and professional.
Launched recently. Early traction's been interesting. Would love feedback if you’re in this space or use e-sign tools regularly.

It's an email-only Korean (and English) language learning service started by me and my partner! We've both been interested in language and, since I've been learning Korean and she's been improving English, I've been looking for a modality that works for me -- apps don't click for me for some reason.
It started by me sending myself an email everyday with new Korean vocab/grammar, but we thought it would be nice if it responded with corrections and learned from my common mistakes to make better questions. So, we've built it out to work for us, and turns out other people also like it and are growing everyday!

Tech Pizza Mondays has been going well, as the Toronto HN meetup. If you're reading this on HN, you're welcome to join us -> URL Mondays.Pizza details on fedi.
We just finished Toronto's Pizza Day, our fifth year in a row and most successful so far. toronto.pizzadao.xyz will eventually get updated to next year's event invite.
I threw a fun experimental comedy party, and I plan to throw another in August. Having a volunteer cast was great, the clown burlesque was shockingly great. I hope to find some team members who want to join forces and put on the greatest talent show this town has ever seen!
Working on founding a school in Toronto has been very difficult, feels like I'm making zero real progress over time. If anyone cares deeply about education, I'd be happy to talk. I'm extremely enthusiastic about the Sudbury Valley School model.
And this last week I started a fitness club, where most weekdays we do strength training with giant wooden swords. Looking for people who want to join up and get strong and have fun!

Build tools are generally an un-sexy field, and JVM build tools perhaps doubly so. But Mill demonstrates that with some thought put into the design and architecture, we can speed up JVM development workflows by 3-6x over traditional JVM tools like Maven or Gradle, and make it subjectively much easier to navigate in IDEs and extend with custom logic.

Think of it as a true drop in replacement for postgres that runs on multiple nodes. It internally does replication, sharding and leader election. Just add more nodes and you get to increase both read and write scale.
I personally am working on a few things like online major upgrades, async replication for DR, enhanced backup/restore/pitr/clone capabilities, and more recently supporting DocumentDB extension which provides a true Mongodb API.
Being a startup I also get to talk with large customers, help with marketing content, and participate in database conferences.

Checkout how posthog did it [1], it's an interesting approach. Having something that can support both devs and content folks (non technical) is great. It is easy to get bogged down in building the website and reinventing bunch of wheeels, instead of focusing on the product & content, esp in smaller teams.

A developer-focused IoT Cloud Platform. The idea stems from pain points experienced while automating an indoor farm a few years ago where I had to spend way too much time building the data collection and analysis infrastructure instead of focusing on the actual automation.
Devices connect via secure MQTT, HTTP, or WebSockets and send structured, typed data. Each device gets its own sequential mailbox for messages. You can trigger webhooks or broadcast messages to other devices based on incoming data, powered by programmable actions.
Just deployed to production. Currently working on Device SDKs (coming very soon) and time-series analytics. Check out the platform, we're in technical preview now. Happy to answer questions and appreciate any feedback.

I have a software engineering background, and I’ve been working on this for nearly 3 years now! I used to play with the Electra One controller before, but having the encoders over the display is really something I’ve always wanted.
I presented Karl last month at Superbooth (a fair in Berlin) and got really good feedback. After 6 months of beta and 2 years of touring with it myself, the first batch will be dispatched in August, and this is quite exciting!

Here’s a simple app my toddler made to generate toy trains[0].
“Real users” are using it to build personal software tools like finance dashboards, content generators, and educational apps.
Right now the functionality is great for many simple tools, but it’s notably lacking a first-class data layer (coming soon!).
All of the AI-generated code runs in secure MicroVMs, and the front-ends are just static assets, meaning the apps scale to zero when not in use.
We’re currently in the process of making the builder less of a “workflow” and more purely agentic, which should improve the overall success rate.

The goal is for you to get complete and honest feedback from the team you work with. The killer feature is we make it quick and easy. And your reflectors can never initiate the instance of giving of feedback, the system invites them; this avoids the "but I am angry now" situation.
You can add the team members you work with in any setting and specify how often you work together. Depending on that, they will get the chance to reflect on you between every four weeks and every eight weeks. A reflection takes literally seconds.
Sign up is invite-only atm but invites are handed out pretty quickly since we want the feedback! Just sign up for the wait list on the site [1]. It will be free because we have a business version [2] that will support it; and the personal app will hopefully generate interest in the company one.
You can send feedback to "admin" at the domain of the company one [2].

Been a freelance dev for years, now going on "sabbatical" (love that word) very shortly.
Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.
I'm excited.

I posted about this on last month's thread, and mentioned in a descendant comment that I was going to PyCon US in May. Someone well-meaning asked if tech conferences are in tune with working on myself. I just got back from PyCon. Yes! It was an incredible experience. Not for learning technical things from talks – the talks are mostly online already – but for the social and community aspects.

For older kids I've been making it easier to write games in Godot using TypeScript:
https://breaka.club/blog/godots-most-powerful-scripting-lang...
I'm building tooling using this technology which allows kids to create their own games, this is itself presented as a game kids can play through. Basically, imagine if Roblox actually delivered on its promises to kids.
Most of what we're building will be open sourced, so that older kids / young adults will be able export their projects and share their creations stand-alone.
Of course, telling kids they can create their own game is only relevant is kids want to do that. We're not locked into one way of thinking. We've also modified Overcooked 2, a traditionally co-op game and introduced a visual scripting platform which allows kids to code their way through levels:
https://www.youtube.com/watch?v=ackD3G_D2Hc
Overcooked 2 won't be the only game for which we do this. Introducing coding to existing games is a fun way to teach kids to code, without yet burdening kids with too much creative freedom. Kids already want to play these games, so this approach allows us to bring educational tooling to kids rather than vice versa.
I used to be Head of Engineering at Ender, where we ran custom Minecraft servers for kids: https://joinender.com/ and prior to that I was Head of Engineering at Prequel / Beta Camp, where we ran courses that helped teenagers learn about entrepreneurship: https://www.beta.camp/. During peak COVID I also ran a social emotion development book subscription service with my wife, a primary school teacher.

- Suggest a professional summary (with highlighting) to match a job description [0].
- Preview as you go.
- ATS friendly templates.
- Find relevant jobs for my resume.
[0] Recruiters skim through resumes, and highlighting the keywords they look for has always helped me to get their attention, so I decided to implement this feature using AI.

* Vectors are stored in Lance format directly on Cloudflare R2
* Search is done via Lance, comparing natural language queries to image vectors
* The whole thing runs on Fly.io across three small FastAPI apps (upload, search, frontend)
No Postgres or Mongo. No AI, Just object storage and files.
You can try it here:
Or see the code here:

This involves exploring the ethics of using magic to accomplish tasks. The problem then boils down to a matter of epistemology— a testing problem. But testing is something you only do in the absence of trust. So critical thinking begins with the rejection of trust.
It’s been interesting to read about “Anomalistic Psychology” which is the study of magical thinking. Malinowsky commented that not a single canoe was built by Melanesian islanders without the use of magic, yet none of them would say that they could be built without craftsmanship.
Magic is the belief in the infallibility of hope, to paraphrase Malinowski. Which may explain why too many smart people are uncritical about LLMs.

2. Plowing through the "AI Agents in Action" book. I'm just wrapping up the section on AutoGen and about to move into crew.ai stuff.
3. Reading a book on Software Product Line Engineering.

A social event planning app to capture the fun my friends and I had with facebook events, but without the facebook. We have native apps for iOS, Android and the web. dateit has a generous free features compared to competing apps (SMS invites, photo upload, customization).
My cofounder and I have fully bootstrapped this and now it mostly self sustains which is an exciting achievement!
It's been a fun project to hack on for the last couple years and spawned several interesting side quests. For example, the backend is in Swift (as I started as an iOS dev) so that has been an exciting space to work in.

I've added a react SSR system. It has node subprocess code for rendering HTML from java via stdin/stdout. There's a Node/Vite proxy server that adds the fancy HMR you expect from SPA apps.
It supports multiple roots on a page, every SSR component has data-props and data-componentname, and the entry script just queries those attributes and hydrates everything.
The node renderer script is packaged as an EXE which is deployed in WEB-INF on the server.
It's fun to add the amazing React tooling to an old codebase. It also shows how you really, really, really do not need NextJS.

It’s just a basic IntelliJ plugin which provides an infinite canvas to add code bookmarks to. I work on a large code base and often have to take on tasks involving lots of unfamiliar areas of code and components which influence each other only through long chains of indirection. Having a visual space to lay things out, draw connections, and quickly jump back into the code has been really helpful
The canvas and UI is built using Java AWT since that’s what IntelliJ plugins are built on, but it occurred to me that I could just throw in a web view and use any of the existing JS libraries for working on an infinite canvas. React Flow has seemed like the best option with tldraw being what I’d fallback to.
But then.. if the canvas is built with web technology then there’s no reason to keep it just within an IntelliJ plugin vs just a standalone web app with the ability to contain generic content that might open files in IntelliJ or any other editor. I’m pretty sure the “knowledge database on a canvas” thing has been done a number of times already so I want to also see if there are existing open source projects that it’d be easy enough to just add a special node type to

A turnkey self-hosted home router + app server that you can (eventually) just plug into your modem and go through a simple setup and have self hosting. It's in heavy development, so it requires some experience with NixOS to get running, but the goal is to have it usable by non-technical people.
Current features
- Firewall
- Headscale VPN, apps private by default
- Automated DDNS
- Dozens of apps with automated subdomain allocation and TLS cert management
- Ad Blocking
- Customizable public landing page
- Single module configuration for all features
- Automatic backup for all apps
In Work/TODO: - Better landing page and contribution process
- Admin Dashboard, Config page
- SSO across apps
- Ability sync to a cloud instance in case you no longer want to host at home
- Ability to mesh with friends/family/associates for social networking, distributed backup, distributed CDN, etc
- Getting others to install it and build a community
Aspirational: - A standard protocol or tool for updating DNS entries at registrars
- A standard protocol or tool for updating modems with suitable settings for self-hosting
- a free DDNS service to provide to users of HomeFree

It works by connecting directly to Linear and dispatching assigned tasks to agents that submit PRs in GitHub when finished. My agents work in a fully-integrated Linux development environment, including internet access. This means that they can browse the web, install dependencies, and creatively work around environment issues to make sure they run and test the code they ship.
It's really gratifying to see people asking all over the internet, "Where can I just create tickets and get pull requests?" because that's exactly the workflow I built CheepCode to support. As an engineer for almost 15 years, I knew what I personally wanted, and it really makes me happy to see that what I built will work for so many others too.
As a bootstrapped solo founder, it's challenging to juggle product/growth/development/strategy all at once, but also incredibly rewarding. I wouldn't necessarily say no to funding ;) but in the meantime, it's quite a thrill!

It uses GPT-4 for story generation, ElevenLabs for narration, and a simple Next.js + Supabase stack for the app layer. I’m experimenting with story memory (so kids can revisit recurring characters) using vector embeddings, and building a “choose-your-own-adventure” mode with dynamic audio rendering.
Biggest challenge so far: aligning narration, ambient sounds, and story pacing without sounding janky or robotic. Solved it by tokenizing and chunking the story for synchronized audio stitching via ffmpeg.
Another challenge was the inconsistent image illustrations via Dall-E 3. I’ve adopted a dynamic prompting method that includes as many details about the scene, character details, and other visual elements which should remain consistent on each of the storybook pages.
If your kid ever demands “one more story” after a long day, I built this for you. It’s had a meaningful impact on my son’s behavior.

In contrast to the popular arena based allocators (which target quickly allocating/freeing short lived per-request allocations), I am targeting an allocator for build very large in-memory dbs or caches with almost no garbage collection cost.
There's a little no-gc string interner package in there as well.

Related to the memorymanager, as in intending to support it are
https://github.com/fmstephe/fuzzhelper A library for setting up fuzz tests for complex data structures.
https://github.com/fmstephe/gossert A library for adding runtime assertions to Go code. It's developed so that when the assertions are switched off the compiler should be able to completely eliminate the assertions. But this requires build tags to switch the assertions on.

Growing a coding agent as a "game": https://github.com/dhamidi/smolcode. Started with https://ampcode.com/how-to-build-an-agent and then asked the agent to modify itself. It's so much fun and hard to stop!
Since coding is cheap now, I'm building a web framework for myself, using reasonable defaults: built around the transaction log, single binary deploys, sqlite3 for everything, runtime introspection tools to make ops easier.
I want the framework to "compile itself out of the project", so that projects don't have devtime dependencies and can be easily edited by Cursor et al. It should still stick around in the form of a high-level CLI that an AI agent can leverage to fulfill common tasks (e.g. add a new UI component, query, command, etc).

My co-founders and I are building an AI assistant that helps immigrants navigate Finnish bureaucracy. As immigrants, we've experienced firsthand how fragmented and inaccessible essential information can be, scattered across Migri, Kela, the tax office, and municipal websites, often only in Finnish and Swedish.
We're using RAG (Retrieval Augmented Generation) to create a multilingual chat interface that connects people to official resources rather than replacing them. The system reduces "failure demand" - support requests that arise because people can't achieve their goals through existing resources.
The technical approach is a multi-agent system in which specialized AI agents handle different domains (immigration law, employment, housing, healthcare, etc.). We've named the agents after Finnish mythological figures (such as Tapio, Ilmarinen, and Sampo) to create a cultural connection while providing practical assistance.
Interestingly, this addresses a systematic problem - government agencies spend significant resources on repetitive support that could be automated. At the same time, immigrants get frustrated trying to piece together information from multiple sources.
We're exploring B2B opportunities (companies relocating employees, municipalities, healthcare systems recruiting internationally) and EU funding for integration technology.
Happy to share more details or get feedback from anyone who's worked on similar multilingual AI systems or government-facing tools.

- For node, that means it installs eslint + prettier / biome,
- setups all the plugins,
- sets up typescript with watch mode using tsx and alias support,
- installs vitest with all configuration,
- installs dotenvx and configures it to use separate development, staging, test and production configuration,
- installs commitlint, commitizen to ensure all your commit messages adhere to specific conventions,
- installs lefthook / husky to run tasks before commit, on push etc.
- Adds github actions for linting, running tests.
- Creates a docker development, testing, staging and production setup with different dockerfiles for each.
- Development version installs self signed localhost SSL certificates for use by nginx/traefik/caddy.
- Test environment runs all tests inside the container and shuts it down,
- Staging environment mimicks real production as closely as possible with minimal resource consumption.
- Production environment uses actual SSL certificates issued by the likes of zeroSSL or letsencrypt with a highly optimized dockerfile for minimal footage.
- Direct deployment to AWS / Azure / GCP
- Python version does a tonne of stuff too. Will share if anyone is curious
- What is special about this? As dependencies change, the boilerplate also updates itself, runs the tests and passing configuration is cached

I'm working on a WhatsApp to Signal relay. I.e.: whenever someone sends a WA message to you, it appears in your Signal. You can reply and it will go back to the original sender.
Why? I'm privacy conscious and don't fancy using a Meta product. But some of my friends/associates/family still insist on WhatsApp only. Running this WhatBridge service on my micro server behind a VPN allows me to communicate without having WhatsApp on my mobile.
Behind the scenes, it connects WAHA (https://github.com/devlikeapro/waha ) and Signal CLI (https://github.com/AsamK/signal-cli). Still early stages, but getting closer to a workable state.

I've found it really satisfying to solve the data challenges that come along the way, from "where on earth could this data come from" to collecting, storing, parsing, validating and serving constantly. It's also - by nature - something that's never going to be "done". There's always something to improve. I love it!
We now offer more types of data (ASN/whois, proxy/threat detection, so on) than most other providers, more accurate and more frequently updated, at a tenth of the cost, which is something I'm really happy about.
For anyone interested, you can make 1,000 requests day free, or reach out if you have an open source/public interest project for an unlimited key or access to the data.
I'd also love to hear any suggestions for additional data types to add.

We monitor how companies/brands rank in LLMs/AI Search, we don't use the API but the user interfaces (since these are totally different). We run thousands of prompts to analyse responses and combine that with website traffic to get an understanding of what is being said and how well you rank.
I didn't anticipate Google moving to AI mode so fast, to be totally honest, which makes it really interesting because we likely see rank tracking and keyword tracking disappear in the near future.

Once I’m happy with my take on a reference implementation I’m hoping to create some tooling with it to do some interesting analysis of CSP abstract syntax trees to identify things like policy anti patterns, reporting on capabilities a policy grants to a domain/resource, and a better mechanism for allowing tools like OPA, SemGrep, etc. to define and enforce rules on a policy.

Short description:
- Client generates RSA keypair and connects to server from <1024 TCP port, sends pubkey. - Server uses reverse DNS to come up with cert name (rules can specify alternate CN and SANs, override TTL, etc). - Server generates a signed cert and connects back to client on <1024 TCP port and sends cert.

1) a note-taking workflow in Obsidian (you take bite-sized notes about a topic, then connect "prerequisite" notes in Obsidian's canvas editor)
2) a tool that uploads each note and graph data to a database
3) a webapp that presents those notes algorithmically using spaced repetition. This enables you to allow others to "traverse" your note graph in a guided and self-paced manner.
You can add "challenge presets" to each note so that your mastery of each piece of knowledge can be tested with simple flashcards, multiple choice, free response, or some visual/actionable task to force active recall. An algorithm uses your success rate and spaced repetition data to introduce & drill more advanced notes into your long term memory.
Here's some more reading I was inspired by:
https://www.mathacademy.com/pedagogy
https://www.justinmath.com/individualized-spaced-repetition-...
Even if there are a lot of imperfections and flaws about this project (like the sheer difficulty of curating a good knowledge graph to begin with), I'm hoping to make my note-taking in Obsidian more structured and thorough, replace my Anki routine, and make any of my notes into an automated + algorithmic course. If someone has another similar project (combining note-taking with hierarchal, topological knowledge graphs with spaced repetition and testing all in one platform) I would love to hear more about your approaches. Quick shoutout to one person I've seen who is doing something similar: https://x.com/JeffreyBiles/status/1926639544666816774

Separately, working on building an app to assist with cipher analysis of things like Kryptos and Bitcoin/crypto puzzles. Loosely modeled after CyberChef, but a native app that is capable of far more detailed frequency analysis and brute forcing with the GPU.
Also, experimenting with LLM workflows for both work and the rest of life. Prompt engineering seems like an incredibly valuable skillset for the next decade.

I always felt like collecting all my todos / notes in a single notes app is not enough. Sometimes you want to remember something just for the next time you open this app/window. Attaching the note directly onto the window makes sure you won’t forget on it.

- Works by selecting traits, which then trains a model(flux) OR uploading your own photos.
- Hopefully useful for shopify/ecomm store owners, digital agencies, or just about anyone to drastically speed up the time and reduce the cost to test creatives, create media content, or just do what you want with a model of yourself.
- Web with Nextjs, DB with Supabase, marketing with nothing.
- Happy to share more details into how we built this, and hear feedback and thoughts.

In short: installed immich(instead of Synology Photos), Beszel, Paperless-ngx(configuration pending), moved a bunch of tools out of my HTPC VM in to separate VM, did a proper backup of my proxmox cluster and set up cloud-init template with new ubuntu.
Due: gitops style deployment and terraformation of infrastructure(provision proxmox VMs via terraform) and auto redeployment of docker containers across 5 machines. Probably would need github runner in my network. Also Authelia is still missing in my lab, I need to get to that soon

Instead of integrating, maintaining and paying for multiple tools, everything is available in one simple to use dashboard.
For those familiar with PostHog, you can think of it a simple version of that.
I've been developing it and testing with few startups and plan to start promoting it more soon once the MVP is bit more polished. Also more tools are on the roadmap.

I made it because the desktop software I use (ImageOptim) doesn't support Jpegli, which I find to be much better than mozjpeg for most types of jpegs used on the web.

I started the project around a year ago, then got a little stuck and forgot about it for a while, until now.
For anyone curious about the technical details, it's a Rust program that wraps `ssh`, copies a small statically compiled binary to the remote, and uses SSHFS/SFTP (haven't decided yet, maybe configurable?) to allow your local editor to access the remote files as easily as local ones

Until recently, it was cost-prohibitive to gamify topics with indefinite answers and progressions. As a result, "left-brained" topics have been gamified for years, but "right-brained" topics have resisted gamification. LLMs and generative AI unlock game economics for unstructured text.
Casual gaming is only category outpacing passive, social media. The most direct way to elevate humanity's media appetite is to turn human greatness into casual games.

The idea came since Omnivore decided to shut down. It is open source and self-hostable but the whole system has so many bells and whistles that nobody would want to self-host it. Even more, even if I am able to export all my data, I will be unable to use their beautiful client to view my data or build anything of my own because I am not good at that.
The idea is to have a read-it-later app that has modular components each of which can be self-hosted independently which talk in protocols. So a different data crawler module that can take many forms - browser extension, Telegram bot, or something else, that takes an URL and posts the page content to a server.
The server will have modular parsers that are extensible to support different websites and pages, contributed by community (similar to Telegram's parser or Calibre's). It then converts it into a common format to be stored.
The storage should also be pluggable so that I can easily store my data wherever I want - whether locally as MD files, on S3, or on an SQL Database. This also should be extensible to allow different storage types like so many other tools do.
Then a web server that serves common endpoints to read, add tags and annotations, and other operations. It just needs the user's storage endpoint and authorization to allow them to access their data. I feel this is going to be the most challenging.
Let users create their own clients that render this for users. Just like Telegram and Matrix.
This idea resurfaced recently because I wanted to try getrecall.ai but it looks too expensive and I am worried about privacy. Having a setup like this would allow me to plugin a local LLM to this system as well.

- Improving onboarding experience
- Tapping new growth channels (Organic SEO, Paid ads, Integration marketplaces)
- Resolving customer support tickets and minimizing ticket flow in general

This is an example view-only trip: https://ikuyo.kenrick95.org/trip/2617cd98-a229-45d4-9617-526...
So far it has:
- Timetable view, with drag-and-drop support. I think it will be useful for planning the activities as I need to be able to quickly swap activities - List view. I think it will be useful for actual travel itself as the day go, I'll need to focus day-by-day - Maps. To make it easier to plan nearby activities, but I think I still need to rely on Google Maps or other kind of maps since I still need the navigation/direction in-between activities - Sharing & comments. Since I plan to use it to collaborate the travel with my friend, this is a must-have feature for me. - Expenses. This is still quite basic but maybe I should also track who owes whom...
I think now I'm happy with the feature set and will start planning my travel using this to polish the UX :)

I’m also planning on adding more detailed (left to right audio) panning and other output controls, oriented towards using BeatScratch live with other musicians. My hope for this is to use it to complement my own musical practice I’ve been working on, outside of all this 1s-and-0s programming time.

Chancy is a postgres-backed task queue for Python that scratches a lot of the Celery itches. It's not meant for folks that need to run a million tasks a second, but for the majority of projects (many millions per day) it offers:
- Robust job support, including timeouts, memory limits, retries, global uniqueness, global rate limiting, scheduling (cron and "in 10 seconds"), priorities, etc...
- DAG based workflow plugin
- It's asyncio-first with support for threading, multiprocessing, asyncio, and sub-interpreter tasks so each job can use the optimal concurrency model. Workflows can mix tasks across multiple queues and concurrency models.
- Can be embedded inside your existing ASGI servers - great for things like development docker containers or containers deployed on say, unraid.
- Worker's handle scheduling (no need for `celery beat`) and have an optional built-in dashboard.
- 1 infrastructure dependency (postgres) and 1 required package (psycopg3) - with everything else isolated in optional plugins. - Dynamically re-assign queues to new workers based on tags, add, pause (with auto-resume), modify or destroy queues at any time.
- Highly observable - unlike Celery, you can just query your database when needed to see the entire system state
- Portable - Linux/Windows/OSX
- Permanently free and open-source without any "premium" or paid features.
- Django integration - ORM/models, admin, and django auth integration for the dashboard.
Chancy is a young tool, but is used in production environments with tens of thousands of users and billions of jobs run with great feedback from early users:
> ...thank you for this amazing library...
> hey, first thanks for such a great library! Chancy has worked incredibly well, and its modular design has made it a pleasure to use. Super lightweight but feature-full; it's a hard balance to strike.

Along the lines of predictionbook, metaculus - something that helps you be "well calibrated", but more playful/fun than metaculus.
It doesn't have a lot of upside - predictionbook actually went offline due to lack of interest. But it was a good excuse to try out some vibe coding, and learn react native (I've mostly been a backend programmer).
In an attempt to make it more engaging and fun, I decided to have it focus on sports picks. Also partly because calibration graphs need to have a lot of predictions to yield any reliable information about your calibration.
I got it up in time for March Madness and about 25 of my friends joined and it was a good time. I nagged and reminded them a lot about about 15-20 of them predicted all 63 games, by picking the winner of each match and what their percentage confidence was. I had a leaderboard and live-blogged and gave silly awards.
I later added support for multiple "tournaments" and currently have tournaments going for NBA Playoffs and NHL Playoffs, but interest is waning. Of my friends, only 2-3 others are still regularly predicting.
Maybe it'll be more fun for the NFL season but I might also let it go a bit dormant.
Biggest challenge is that there isn't really a bulletproof way to rank people if people only predict some games in a tournament. I've tried all sorts of things, minimum # of games, bayesian kernel smoothing, but it's ultimately arbitrary when choosing how to penalize someone for not participating.
If I were to continue I'd be looking at things like automatically integrating with sports apis and odds/bookmaking apis, allowing users to create their own tournaments, etc. But ultimately, the UX of the site isn't much more than making a prediction, and then checking back later when the game is over to see your score. Not much more reason to hang around on the site than that.

Sereze guides personalized breathing techniques like Box Breathing, Yoga Nidra/NSDR, and Silent Meditation, tailored using your Apple Health data (HRV, HR, sleep). It works completely offline with no logins or server sync — just phone and your Apple Watch.
It tracks heart rhythm and variability in real time during sessions, then uses LLM/GenAI to offer personalized insights into your nervous system health, sleep recovery, and stress resilience. You can even ask it questions post-session and receive contextual responses.
Recent features include TTS-guided breath cues, REM/Deep/Core sleep stage breakdowns, and a silent mode for mindful journaling or meditative tracking.

I've been experimenting with a custom workflow to turn long-form videos into short, engaging highlight clips. I know a bunch of startups are in this space, but I wanted to build something lightweight and flexible just for fun — and ended up integrating it into one of my products.
Here’s the general flow:
Transcribe the video Use tools like Whisper, AssemblyAI, or Deepgram to get an accurate transcript.
Extract interesting clips Feed the transcript into an LLM (I recommend Gemini because of its long context and quality) and prompt it to segment the video based on criteria like "viral", "engaging", "funny", etc. Make sure it returns timestamps.
Generate the clips Use ffmpeg to slice the original video using those timestamps.
(Optional) Auto-crop for vertical If the user selects a mobile/short-form format, use something like Sieve to auto-crop and center the subject for vertical (9:16) output.
(Bonus) Enhance captions Run the extracted clip transcripts back through the LLM to pick out keywords or phrases to emphasize in the captions.
Add captions with styling Use Remotion or similar to render the clips with styled, animated captions. The component handles logic for timing and highlighting.
Render and download Batch render your clips and you’re done.
I used this exact pipeline to build a feature in one of my tools: https://www.shortsgenerator.com/highlights-generator

It started out as a cloud runner for small (mostly pure) composable javascript functions that we run for you in the cloud. So whenever you have some small code snippet that you want to run, you can hit up microfn.dev, paste your code and then plug it into wherever you want (pipe into the terminal, use from MCP, add a cron to it, add to Siri shortcuts, use for home automation, ping it with webhooks, etc)
Now we added agents support, so you can have autonomous AI agents take your functions and decide when to use them. Even better, you can hook microfn into a MCP and have anything that supports MCP use those functions as well!
Suppose you need a new thing that your agent should do, you could ask the agent (whether that's claude or cursor) to compose a new function, add it to microfn, then use it itself going forward!
microfn.dev wants to be a toolbox for composable small tools. Imagine a toolbox at home with a bunch of hammers and screw drivers that you collect, share, and use for different purposes.
Some actual examples:
- Pull data off services (twitter, etc)
- Store data from sensors somewhere
- Give agents tools to talk to your specific systems without needing to write an entire MCP
- Wrap complex logic (eg slack auth + sending a message to slack) into a function and add it to a Siri shortcut, so you can quickly send messages to a specific channel with a ping or curl
Still very early alpha (beta-ish), but very excited about this

Hey everyone, I’m building my next project and would really value your input. I’m exploring two directions — both designed for mid-to-senior technical builders: AI Agent Builder: Create complex, production-ready agents from plain text in minutes. Fully code-ownable, transparent (not a black box), and easily connectable to modern tools — even the latest YC startups with APIs. Cursor for APIs: A dev-first tool to connect to any API instantly. Just type “build a RAG system for…” and it suggests the best tools, then generates the right code and surfaces the latest docs — including niche APIs. Think of it as a fast, intelligent API library with copy-paste-ready code. Which of these would actually improve your workflow?

An app framework targeting modern C++ (>C++20) based on Boost.Fiber and stdexec( sender/receivers when C++26 releases)
I got inspired by a recent Java talk[1] from a Netflix employee about how they are building. I have the pretty strong opinion that async/await are implementation details and shouldn’t be exposed in APIs. They effectively have the compiler/runtime generate a state machine for you and you wouldn’t put a state machine in an api. Using C++ though we do have low level access to the CPU and there is no reason we cannot just use stackfull coroutines. This allows you to write literally synchronous code but it will defer blocking operations to an even loop and allow concurrency.
For GUI at least in the beginning Im thinking that I just spawn a native window and it’s up to you how you draw to that. I’m targeting something basic on linux myself which means it will probably just be direct calls to the wayland compositor to create a window. Getting a context etc will be up to the user since my idea would be in windows we use C# and on macos we use swift for UI. Documenting and building tooling around getting those languages integrated feels like it would provide more benefits than actually trying to reinvent the wheel in C++.
Likewise HTTP client will just wrap libcurl, for server side Im actually thinking of just calling into golang. HTTP servers aren’t the hard part, it’s all the infrastructure around it that is the hard part and well golang handles that better…

It's an open-source (AGPLv3), purpose-built log analytics UI specifically for ClickHouse. I've been using ClickHouse for logs and love its power, but found the existing UIs either too heavy, too focused on ingestion (which we already have covered with tools like Vector/Promtail/Fluentbit/Logstash etc), or not ClickHouse-native enough.
Logchef aims to be a lightweight, powerful log explorer that sits on top of your existing ClickHouse setup.
Key things:
- Schema-agnostic: Works with your existing ClickHouse log tables. No need to change how you store things.
- Dual Query Modes: Simple search syntax (e.g., level=error service=api) for quick looks, and full SQL for complex analysis when you need to dig deep.
- Lightweight & Focused: Single binary, easy to deploy. It doesn't do ingestion, letting you use best-of-breed tools for that.
- Team-centric: Built with multi-tenancy for teams and access controls for different log sources from the get-go.
I've got a demo running at https://demo.logchef.app if you'd like to try it out. It's still evolving, so feedback (especially from other ClickHouse users) would be super valuable!

This is mostly a hobby/community help project. Majority of schools in my area are either not required with computers or they have lots of older ones with no funding to maintain our modernize them.
I'm trying to setup everything within VPN (either wireguard or tailscale). I'll most probably go with tailscale so I can use the subnet router.
The zero would would run the older RPiOS (32 bit) and would autostart a rdp session using xrdp client. It's pretty usable for mostly static work that students need in schools.
Each RPi unit would cost around ₹2500 ($29) which includes all the adaptors, power supply, sdcard etc.
On the server side I'm running two Ubuntu server OS VMs (inside proxmox) configured with XFCE4 and KDE.
The work is still in progress, I'm yet to iron out major bugs.

Here's a presentation, includes examples: https://hg.sr.ht/~oofoe/candheat/raw/dox/intro.pdf?rev=tip
It's fairly free form, so you can do almost anything you want, but still structured and "legible" for computers and the person debugging it. I wrote it in a Lisp that compiles to JavaScript, but there's no reason you couldn't implement it in any language that supports associative arrays -- idea is that the language has most of what we want, just need to organize it a little. I think the idea is useful enough, that it's potentially useful for more than "just" games.

About 800 SLOC, compiles down to just under a hundred lines of JavaScript. This includes the utilities, the "engine" (keyboard handling, overlays, text and art composition, animation, sound effects, etc.) and the game logic itself (which includes a level editor).

The DevEx isn't quite as easy, but I'm very happy with the final result. I don't have to run the overhead of a Docker Engine anymore, the network policy is far simpler to write and audit, and I can use the same logging tools for both containerized and non-containerized services.
The main hurdle has been file permissions for the mounted volumes for my data; Podman is rootless by default, which means you _should_ build your containers to run as non-root UIDs/GIDs and map them onto host UIDs and GIDs, then grant permissions for those host users and groups to access your data volumes. In practice, the easiest path is usually to run Podman in rootful mode, which is not a best security practice but avoids the difficult-to-troubleshoot file permission errors if you don't do the UID/GID mapping correctly.
However, unless you are really trying to optimize for overhead/performance, you should probably use k3s.

I'm working on the next major update for LookAway. I'm improving the wellness reminders to be smarter - instead of nagging you on a timer, blink and posture alerts now only trigger when you actually need them.
Also adding productivity stats so you can see how taking proper breaks during prolonged screen time affects your work output.

My co-worker and I started this as a side project because we were building so many sample apps, proofs of concept, and engineering as marketing apps and we were feeling more and more locked into Vercel every day. So we wanted to go back to client and server separation and when we did that, we realized most hosting providers have moved toward server-side rendering as the default.
Client-side rendering isn’t for everyone, but plenty of people still make simple websites or even complex CSR web apps and don’t want to deal with fully integrated solutions like Vercel (and Netlify now to a lesser extent). Plus they want the flexibility of choosing different tools for their frontend and backend.
This remains a fully bootstrapped side project for us, but it’s gotten the most traction of any side project either of us has worked on.

TINY attempt to fight the growing divide between "AI haves" and "AI have-not" with
- PREPAID access (+ bring-your-own-API-keys alternatives for more technical users) to premium models (ChatGPR plus and above)
- multi-channel access (SMS/MMS, Whatsapp + many many more) to give ANYONE, ANYWHERE, regardless of how non-technical they are access to absolute TOP/SOTA model advisors with easy access in their language + fact checkers + more (think african farmers looking for intelligence to grow best crops, former delinquents lookeing for rehavilitation, absolutely anyone deservers ACCESS TO INTELLIGENCE)
- zero lock-in - paid (freemium, but no adds) product, but 100% open data formats, sharing, import/export etc.
STAGE: prototype for personal use as a whatsapp bot+ webui, somewhat usable for us but still wip, next stage is building accounts and payments for EU access, next for US/international

The core idea is to ground discussion in a causal diagram that ties together problems & solutions, then each node/edge can have structured details (importance score, arguments, unknowns, relevant facts, etc.) to help clarify & refine the information. It also has some features for working with this information, e.g. comparing perspectives, using a table to evaluate tradeoffs between solutions.
Right now, you basically need to be a power user to get benefit from it, but I've got a lot of ideas for making it smoother, and I'm slowly working through them.

It was in the works for about a year, and I'm now trying to find ways to make it more marketable and useful.
The three main things I'm working on are:
1. GitLab support (GitHub only at the moment) 2. A demo on the landing page that doesn't require any sign-up. 3. Better "vibe coding" experience through the Chat interface for those who want it.
I built it with TypeScript on the front- and back-end, React, Node.js, and PostgreSQL. And I over-engineeres it, as one does, with a Redis cache and websockets to push the latest data to web clients so the latest info is always shown without needing to refresh. I'm using the OpenAI API right now, but I want to switch to local models when I can invest in the hardware for it.
Edit: https://mysticode.ai - Would absolutely love feedback.

- static (mp4) or live (hdmi) input, hdmi output
- a collection of effects (various distortions, color glitches, demoscene-like) applied over incoming video stream, maximum of 4 effects stackable on top of one another
- midi controllers support (controlling actions/params of effects via CC)
- modulation of effects params via LFO and audio events (bpm, kick, tonal detection)
- loading of .glsl shaders (eq. shadertoy.com)
- dynamic input resolution, output either 360p (rpi 4/5) or upscaled to 720p / 1080p (networks like SRGAN over Hailo / RPI or RK3588 with a Radxa 5B SBC).
Given a 2nd screen (timeline editor) would love to evolve this to something like a hardware editor, somewhat in the line of DAWs in the audio world. Most things are working with biggest challenge now being building a control surface (buttons, rotaries + associated oleds, etc) and attempting laying it all on a PCB, a process I don't know much about. If there's interest welcome comments and could elaborate more.

You can drag and drop links from YouTube, Twitch, TikTok, or Kick.
You can add or remove streams, save mixes for later, and share them as links.
You can watch multiple videos at once in a wall-of-video grid and navigate quickly from one stream to another. It works best on a really big screen --phones aren't really supported.
So far, people seem to like it. I've made a lot of updates based on people's feedback since I announced it a few weeks ago.

Most safari booking sites are either outdated, opaque on pricing, or offer one-size-fits-all tours. We let travelers customize everything — dates, interests (e.g. big cats, birding, photography), travel style, and budget — and generate a full itinerary with lodge picks, activity suggestions, and accurate cost estimates (including seasonal pricing and transportation).
We also partnered with local operators so users can actually book what they see — not just get ideas. The goal is to make safaris more accessible and planning less overwhelming.
Still early, but if you're curious or planning a trip to Africa, I'd love feedback: https://greatriftsafari.com

Sensing effectively by optimal (re)positining of the sensors (both number of sensor and physical placement) Think spatial sensor/data fusion, perhaps using more cheap sensors rather than few expensive
Building a model of the dynamics (based on both reasonable assumption about the system based on grounded physics, and dynamical interpretation of the sensor's data (PySINDy, DMD)
And eventually controlling the dynamics

While it may sound counterintuitive, the agents of today aren’t truly autonomous in that you need to really guide them and plan their actions well.
I believe this is true today, and will be even more true when agents are guiding agents.
We need new infrastructure for dynamic context management.
The answer is not as simple as “hook up your agent to an MCP that pull docs from the web” … also MCP needs its own revolution. I tend to use no MCP and prefer raw agent performance.
I’m evolving the simple concepts I built in my VS Code extension to address this. Nothing public now, but I and a few others use this everyday to feed parts of large codebases into Gemini (to build plans for Claude code, other coding agents): https://github.com/backnotprop/prompt-tower

Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.

Most AI agents today are like smartphones without any apps. Ninja.ai makes it easy for anyone to install and use AI tools (MCP initially) that automate useful tasks, without needing to write code.
Think:
- One-click install for AI-powered tools (MCPs, Model Context Protocol servers)
- Automatically share relevant context so tools know what you’re working on
- “Recipes” that bundle multiple tools into workflows (e.g., check inbox → pull receipts → send summary to accountant)
We’re focused on everyday users and small teams who want to get things done with AI — not configure it.Still early. Just launched our prototype. Bootstrapped so far, now fundraising.
If you’re excited about agents, app ecosystems, or making AI useful to normal people, I’d love to hear your thoughts.

We're focusing on a niche here, helping customers to onboard onto Mirakl-powered marketplaces, but hoping to expand to other marketplaces soon.

I think I've finally gotten it to a point where it's usable and it seems to work on my phone as well. Hopefully baking in the lighting for the 3d models will give a small performance boost and I don't think it will be noticeable at all with the color changes and small movements.
I've also been going through the fastai course so hopefully I'll be able to put that to use on this project by generating midi files from audio! I might be underestimating the difficulties there but it should be fun.

While the tourney isn't going year-round, it has a demo mode where you can play through prior years (with friends! Or with yourself on another browser/device). The chat feature is admittedly half-baked and is mostly there to get my wife to quit asking about it. Will try to get that fully done for next year.
I'm also working on another side project in Gleam just to check it out. That seems to be taking shape and once I get something decent I'll post it.
All of these are self-hosted via Coolify on a VPS, which has almost been a project to itself (I've had it with cloud providers). I've learned a lot and it was cool to see some other self-hosting solutions in the thread here.

I would like a phone app that would disable anything that a user doesn't actually need (not something like the existing google android feature that identifies apps that haven't been used in x months). It may ask a user what they actually need (for example, calling, SMS, a browser, etc.). The app would identify all the software/apps on the phone that are not required for the above needs and identify / disable them (say for example Location services). When you get a new phone one could start off with an absolute minimum.
It would need ongoing updates, as the app universe and surveillance technologies continuously evolve.
by kegs_ on 5/25/25, 10:26 PM
I think it works great! The problem is, I think it works great. The issue is that it is doubly-lossy in that llms aren't perfect and translating from one language to another isn't perfect either. So the struggle here is in trusting the llm (because it's the only tool good enough for the job other than humans) while trying to look for solid ground so that users feel like they are moving forward and not astray.

I tried self-hosting Sentry recently and found out there are a lot of moving parts, which makes sense for their scale and use case.
I was wondering if I could build something small and not multi-tenant. So I started experimenting with writing a server (in Go) that collects OpenTelemetry data and inserts into Clickhouse, an API for retrieving data/statistics (P95 in a time range, etc...), and a frontend (React.js) that displays them. All of this in a single executable file (yes, including the frontend, but not including Clickhouse).
This is all very new to me so I'm learning Go, Clickhouse and OpenTelemetry at the same time.

Unlike most programs, which just work in Fil-C with zero or no changes, libffi needs to basically be rewritten. Instead of using assembly for reflectively crafting calls it needs to use the Fil-C zcall api. And instead of JITing closures it needs to use the Fil-C zclosure_new api.

I got tired of using the AWS console (the UI is inconsistent across services, resource-heavy, and loaded with things I don't need)
I've built a handful of features, mostly to scratch my own itch, including:
• Multi-region mode (select 2+ regions and see all your resources on the same page)
• Automated diagrams (tree-style resource relationships)
• Easy export to CSV
• Reference matrix of AWS service/region availability
The best way to explain it is with a demo, so I built a demo version: https://app.wut.dev/?service=acm&type=certificates&demo=true

I've been working on this on and off since last couple of months to consolidate all of my digital knowledge-base like notes/links/pdf etc with the help of LLM/RAG. It is fully self-hosted with very minimal setup instructions - which should be easily installable by anyone on their local machine.
UI is very bare minimal. It still has some rough edges when it comes to the UI part, but usable. I've been regularly using it since sometime, and it works well (atleast for my use case) when it comes to searching and organizing personal knowledge-base.

I'm building a simple outliner focused on core functionality: hierarchical notes, backlinks, file attachments, and todo management. The goal is portability and longevity - it runs in phpdesktop as simple php, js and sqlite without compilation or complex frameworks.
I have been a happy user of LogSeq, but the current major rewrite, intended to enable real-time multi-user collaboration, introduce a lot of complexity and I am now more worried about the longevity of that project.
Built with assistance from Cursor, Gemini, and Jules, so vibe coding. Still early stage but functional for basic outlining needs.

For example, if during the conversation someone asks, "tell me how this API call works". It should be able to. 1. find the right API document (requires search) and then 2. 'retrieve' that API document. But if that API document also requires other content (eg Authentication is separate) that will require ANOTHER roundtrip. So I'm currently trying to figure out what the best flow would be for this.

The idea is simple: instead of blasting you with every keyword mention like F5bot, Replyhub filters for posts where people show real buying intent. These are posts where they ask for recommendations, compare products, or look for solutions.
It also suggests context-aware replies and helps collect leads from people who show real interest.
If you want to reach niche communities where people are actively discussing products, it might be useful.
Would love to hear feedback or questions from folks here.

Most tools we’ve tried are either too bloated, too expensive, or limit you to one or two accounts per platform.

Mostly not open source, contrary to how I have historically operated. I think I'll drop them open source as time goes on and money matters less. Kinda feels like I might make more money just open sourcing it all because of good karma tho.
It's all in Python because that's what I could get on the $200 Windows laptop I built it with, I kept it in S Mode as a challenge because I want it to run as constrained as my customer personas might experience.
Present stage is finding those personas and slicing the wares up into offers/products.

While I love the official TypeScript handbook, it's not easy to play around with the code examples or approach it as a beginner. I started working on a complete TypeScript tutorial that also showcases some advanced use cases. All the code examples run in the browser, and there are some neat visualizations that clearly show what the type system has picked up.

I am also trying to kick off a podcast for folks in tech at Bangalore. I hope to start it in June.

I was working on world models / generative environments but without the training data available as an independent researcher, ended up focusing on building with existing geospatial data.
The same architecture of the '24 Genie paper's dynamics model is instead trained on historical data for risk analysis and creating a heatmap in the 2d map. I'll try to adapt this for a more generalizable urban mobility model as well.

>90% of the work to replicate academic research in quant finance is data collection and cleaning. Academics have WRDS, Bloomberg, and research assistants. Others need to find cheap vendors of acceptable quality. Write scripts to fetch and clean. Actual algorithms and analysis (the fun part) are a tiny fraction of the total effort.
Project objective is "good enough" data collection & cleaning for daily frequency equities, futures, and FX. In that order. Annual data budget target < USD 500. Cheaper is better.

You can build webapps very quickly, especially AI-enabled ones, and deploy them on a subdomain. Other users can sign up and use your webapp, and any tokens they use will be billed to them and you will get a large cut (80%) of the margin earned on the tokens billed - as I bill 2x OpenAI API token costs to create this margin.
So ideally you can validate your idea by rapidly building a prototype and evening earning revenue to boot.

It is just now a matter of, cut it now, or include yet one more thing?
I started writing the RELNOTES two weekends ago, yet more stuff started going in.
In the semantic versioning scheme selected for this project, 300 means that it is literally the 300th public release.
There are over 140 new commits and 299 was all the way back in February.
It's going to be very exciting (for the small number of people that know about this project, now nearing its 16th anniversary).

A block-based TUI note/task application using the Charm tools. I know there’s a billion note apps out there, but none fit my mental model, so just hacking my own.
Goal is to have a system of dumping info in and letting organization naturally rise from tagging.
Each tag has its own page that aggregates all blocks tagged with it, and can have a custom page layout depending on the defined “type” of the tag I.e. a person, project, etc.
Tasks are also first class citizens and can be aggregated with dependencies on other tasks.

Sashi is an open-source workflow automation system that lets you turn real backend functions into reusable, shareable workflows—created with AI, validated by code, and executed from a secure dashboard.
*What makes Sashi different?*
- *Real Code, Not Just Integrations:* Register your actual backend functions (Node/TypeScript) with a lightweight library. Sashi uses Zod for type-safe validation and auto-generates UIs based on your return types.
- *AI-Generated Workflows:* Describe what you want in plain English—Sashi’s AI chat interface builds and validates multi-step workflows, connecting your registered functions in powerful sequences.
- *No Admin Panels to Build:* Sashi provides a secure, auto-generated dashboard for your team to run, manage, and visualize workflows. No more custom admin UIs or glue code.
- *Secure by Design:* All execution happens server-side, with scoped API tokens and session management. You control your stack and infra—no vendor lock-in.
- *For All Teams:* Support, product, DevOps, and engineering can automate internal tasks, trigger backend logic, and collaborate—without waiting on developer cycles.
*How it works:*
1. *Register Functions:* Use the Sashi library to expose backend functions with type-safe schemas.
2. *Create Workflows:* Use the chat or flow builder to compose workflows—AI helps connect steps and validate data flow.
3. *Execute & Visualize:* Run workflows from a central dashboard, see results in real time, and auto-generate UIs (tables, cards, graphs, etc.) based on your data.
*Example Use Cases:*
- Support: “Refund a user” or “Reset password” via dashboard, no SQL or custom tools.
- Product: “Send weekly usage report to Slack” or “Find users who abandoned signup.”
- DevOps: “Spin up preview envs” or “Rotate API keys” as repeatable, auditable workflows.
*Try it or learn more:* https://www.usesashi.com/

Initially I thought there is a use-case in finance, but the barriers of entry are incredibly small and the value add is not that large.

What's different with Hypership is that your apps get user auth, page view analytics, event tracking, logging, and an admin dashboard all set up and ready to go out of the box.
It's also a much nicer platform for devs because we host VS Code in the cloud for you as you're vibe coding. That means you can manually edit the code as you go.

I’ve not been satisfied with how AI is bolted on after the fact — reading in one place, notes in another, and AI as a separate assistant. So I’m combining them.
It works over EPUBs, PDFs, and HTML — you bring your own sources (BYOS), and it turns them into a AI scaffolded, structured, hierarchical reading experience.
Already using it for both reading and deep research style deep dives, and its already way better than my otherwise broken workflow!
by sircastor on 5/26/25, 2:32 AM
It’s been a very instructive process and it’s shown me where the strengths and weaknesses are.
As an aside on that. I don’t think AI is going to replace Developers. I do think it’s going to be a rough couple of years while businesses try everything they can to make that happen. And that’ll probably be disastrous for everything.

I implemented a simple first-come-first-serve event RSVP system, and from the event RSVPS it will pull the players into an event management UI from which the organizer can place players into the available courts and arrange matches balanced by level automatically.
The app does ratings calculations fully locally in the browser so it not only works offline but every new match is based on the last rounds' updated player ratings immediately. There is an option to submit matches to be persisted in my hosted service (pkuru.com) so player ratings are retained. The goal isn't to rank players like existing popular systems (DUPR, UTR, etc) but to do matchmaking within an organized session, or before a session.
The web UI and session management app, which is tentatively named FairPlay, is open source on my github. The version I host at Pkuru.com is free to use as well, and currently used by the #1 club (by average skill) in central Tokyo, as well as the highest level club in Thailand.
I don't plan to commercialize it as it is merely a side project but I can't promise the service will always be free to use due to potential operating costs at scale. However, the front-end UI including the session manager is and will be open source.
There's no fundamental reason the system cannot be easily adapted to other sports such as volleyball, soccer/football, or even a 100-person race since the rating system was designed specifically for team based competitions. It can do everything from ranking players in game like PUBG (100 teams of 1-4 players), to 5v4 futsal (asymmetric teams), to classic 1v1 duels as well.
If any clubs or even businesses are interested in using it to manage open play or rec play sessions where people can just drop in and out and be put into a balanced match of the appropriate skill level, please feel free to contact me. The hosted version on pkuru.com is free to use, but I can also assist in my free time on a volunteer basis if you wish to adapt the front-end open source code.

The approach is to perform system scanning using a combination of LLMs and traditional algorithms to dynamically populate a Datalog knowledge base. The facts of the program are constrained to a predefined “model schema” of sorts and a predefined set of rules that encode specialized domain knowledge of how new facts can be derived from known facts.
We generate proof trees / attack graphs from the knowledge base and queries posed to it. The attack graph uses big-step semantics to plan and guide the execution flow, and the system dispatches to agents with tool use to fill in the details and implement the small-step semantics, so to speak. This may include API calls to a Metasploit Framework server or RAG over vulnerability and exploit databases.
We use Pydantic AI to constrain the LLM output to predefined schemas at each step, with a dash of fuzzy string matching and processing to enforce canonicalization of, e.g., software names and other entities.
Tl;dr: neurosymbolic AI research tool for cybersecurity analysis and pentesting.

The retail site is 100% custom code built in Crystal (server) and Svelte (client). The only part that isn't running my own code is our checkout flow -- I let Shopify handle everything after "Add to Cart".
Our system backend is a separate Crystal app which handles inventory management, pricing research, and price prediction. I've developed an ML model to do price prediction and it kinda works?
What I'm actually working on: This is my full-time gig and probably 60% of my time is spent running the business (going to coin shows, buying coins, photographing new purchases, etc.) and 40% is spent writing code to make the 60% run more efficiently :). It seems I have an infinite list of things to do -- improvements to our retail site; Improvements in how to efficiently go from coin to retail listing (turns out you can send just photos of coins to Claude and with the right prompt it will actually give you a reasonably good description that doesn't sound toooooo AI slop-y); Next "big" project is adapting our ML model for paper currency. The taxonomy is similar but not the same and there's a whole world of notes out there that need to be priced.

It's not exactly version 2.0, it's built entirely from scratch and instead of only hacker news, it can also be used for similar forum sites like Lobste.rs, Tildes, Lemmy etc. In fact, it's built in a way such that more website support can be easily added on the fly.
I had restarted this 3 times in the last 2 years. But the current code is finally coming together to be released to the public.
Currently, I already have the reader part working. So one can read posts, comments, expand collapse comments, read articles etc. I don't have the writer part working yet (voting, favoriting, commenting). I am debating whether I should just release the reader part first and then continue working on the writer part and release it as part of update. Thoughts?

- Stores transactions locally in a SQLite database, so in theory you could build your own Front End if mine didn't do everything you wanted. Think someone who wants to do a fancy "year end summary" visualisation. And if you want to do a complex filter, can just write an SQL query to the database itself.
- Has a great UI.
- Allows you to write your own import connector and mix 'n' mash between locally-saved CSV/OFX files and APIs, rather than going down the standard route of only supporting Plaid. Current solutions leave users high and dry if the Plaid connector doesn't work well / they want to import old data (Plaid only gives the last 2 years I think).

rather than manually write prompts for llms (which is like hand coding byte code for cpus), declare a structure and instructions and let the system do prompt writing for you.
it also exposes an optimizer which can do sophisticated prompt learning for tasks.

- Manages the entire range of personal (and maybe business) information/content: Documents, Media, Messages (email, instant, etc.), Contacts, Bookmarks, Calendar, etc.
- Is tag based, so that where to put and find content is easy to answer. Think of a set of flat folders, on one or more devices, within which the files are stored with tags attached. Since people often find navigating/browsing files more natural than searching, virtual folders will be dynamically generated to guide navigation. Also, entire folders can be treated as atomic, and tagged/managed as one object (useful for repositories & projects). And, heuristics (and maybe AI) will be used to automatically tag files when they are imported into the tool, greatly reducing the tedium of adding tags.
- Is file based, so that all information is physically stored as individual files. This allows information to be more easily managed on a physical level: moved around, backed up, exported/imported, searched, navigated, etc. So in addition to docs, each email/instant message, contact, scheduled task/event, bookmark, etc. would ultimately be stored as a file, unlocking all the things you can do with files.
- Has a local web-based UI launched from a local agent, so actual file content does not usually need to move across the network and stays local, and the tool is also easily multi-platform, with consistent UI irrespective of platform.
- Provides a cloud web UI as well, that communicates with content devices through the local agent, so that content stored across multiple devices can be managed in one central location, even without direct access to those devices, team/org features can be provided. However, file content still stays local, except when shared.
- Provides tools for exporting data as file from the data islands of various apps and service, and backing up as files to cloud storage services.
My vision is a situation where I am in charge of my own data irrespective of whatever device, app, or service I use, can ensure that it is always available and will not be lost, and that I can easily navigate and search through it all to find whatever I want, no matter how scattered and massive it is.
[1] Here are some of my issues with personal information management affordances of current tech, which is driving me to work on a solution:
- Our data is too bound to device and vendor islands. Can't easily move my information across Apple/Google/Whatsapp, etc accounts. Can't easily merge and de-duplicate either. I almost always somehow lose data whenever I have to move to a new phone, etc.
- Hard to own your data on many services: Discord, Slack, etc. Can't easily export, search.
- Hard to have a 360 overview and handle on all your data assets and query them in a consistent manner.
- Files as a unit of information storage and management is very ergonomic; we shouldn't allow that concept to be buried by vendors for their own gain.

Now I struggle with a marketing strategy, quite a bit. But hey, I was told it's part of the job ;)

The most exciting thing is I'm working on a way to pre-bake one's WiFi information and an SSH key into the piCore Tiny Core Linux image.
piCore is sort of the holy grail for a lot of people who just want to stick a tiny personal-user server onto a Raspberry Pi and then not have to worry about the SD card burning out on them, because the entire system runs in RAM after first boot anyway - the only thing standing in its way, methinks, is that it requires you to physically plug in a keyboard and a monitor to get it up and running on the first boot.
I think that's dumb. A Raspberry Pi should be a thing you can plug into a wall socket in your home and then work entirely via SSH with. I do a lot of work with Linux images and virtualization like this at my day job anyway, with more scrutiny and regulatory compliance in place - if you can imagine what "embedded devops" might look like, that's a good way to describe it. So I'm a surprisingly good fit by now for this kind of thing.

Currently I'm neck deep in some Fish shell scripting to automate writing posts for https://andrew-quinn.me/ , similar to what I already have for https://hiandrewquinn.github.io/til-site/ . With the latter, I just type in `til` at a terminal, and I
1. Get asked for a title;
2. Get a fzf multi-select list of all previous tags used on the blog (this ensures I actually continue to use the same handful of tags, which makes the blog much more fun to dive down); and
3. Get a vim window open to actually crank out the blog itself.
aqdm doesn't have tags, but it is built on a very similar Hugo base. Honestly the hardest thing about writing this script is simply wrestling with the fish shell programming language. I should really sit down and learn it properly one day...

We changed our modem recently, which broke the cronslave Raspberry Pi I had powering https://hiandrewquinn.github.io/selkouutiset-archive/. That led me to spend the weekend finally moving its codebase off of Raspbian and onto a fully RAM-based Tiny Core Linux.
Running the OS entirely out of RAM for a Raspberry Pi increases its longevity by at least an order of magnitude, because you only ever read from the SD card on boot and on backups. If you configure the server such that everything is ephemeral anyway, you'll basically never see that little green "Writing" LED blink. That's how I got interested in the aforementioned prebaked piCore project!

I collected my smattering of Finnish language learning software projects all in one place at http://finbug.xyz/ . I recently added the ability to mark and unmark words to my Finnish pocket dictionary https://github.com/hiAndrewQuinn/tsk - that makes it super easy to save words during a reading session and then import them into Anki later.
Of more general interest to people might be https://github.com/hiAndrewQuinn/audio2anki , which takes a YouTube URL, runs it through Whisper for an automatic transcription, then slices it up sentence-per-Whisperified-sentence and creates Anki cards out of each transcription for spaced repetition listening practice.
I made this for Finnish originally, but it fills a niche I was surprised to see had no really good locally-runnable FOSS options. There are some startups hawking a similar slice-and-dice service which I'm sure is much higher quality. But I figure the most likely people to get a lot out of a program like this are high school students, who generally don't have credit cards they can buy SaaS with - they need something they can dump their hours into, to get to work, instead of their dollar bills to get something that already works.

Because it's hard to remember how to handwrite complex kanji (many people have character amnesia in real life due to smartphone usage), I casually wondered if it was possible create a Japanese orthography that was: (1) easily scannable (which rules out hiragana); (2) disambiguated words without Kanji; (3) still relatively compact? (which hiragana is not).
I figured a good substrate to start from was romaji + a new emoji system.
You know how people think LLMs can't invent things? o3 just invented this system whose goal is to maximally disambiguates homophonic Japanese words (performing the same semantic compression role that Kanji does today). This is the first iteration. After each romaji noun, it tags it with a geometric shape. These are the 30 tags o3 came up with (based on homophones requiring disambiguation):
| Diacritic | ◐ living | ▢ built / object | ⬢ nature | ◊ abstract | ⟐ action / event |
| ------------- | ---------------------- | ---------------------- | ----------------------- | ---------------------------- | --------------------------- |
| • top dot | ◐• adult / main person | ▢• building / place | ⬢• plant / flora | ◊• idea / thought | ⟐• movement / travel |
| – bottom bar | ◐– child / minor | ▢– tool / instrument | ⬢– water / liquid | ◊– emotion / feeling | ⟐– communication / speech |
| + right plus | ◐+ group / collective | ▢+ vehicle / transport | ⬢+ weather / sky | ◊+ social tie / relationship | ⟐+ creation / production |
| × left cross | ×◐ animal (non-human) | ×▢ food / consumable | ×⬢ mineral / material | ×◊ value / moral | ×⟐ perception / sense |
| | center bar | ◐| deity / honorific | ▢| document / media | ⬢| terrain / landscape | ◊| state / condition | ⟐| change / transformation |
| ‿ bottom arc | ◐‿ anatomy / body part | ▢‿ container / vessel | ⬢‿ energy / fire | ◊‿ knowledge / data | ⟐‿ rest / passive state |
I gave it this wikipedia JA text: 現代における日本語の一般的な表記法は漢字仮名交じり文であり、漢字と平仮名(昔の法令などでは片仮名)を交えて表記する。漢字は実質的な意味を表す語に使われ、平仮名は主に活用語尾[注 1]や助詞に使われる。朝鮮語などでは漢字が主として字音語にしか使われないのに対し、日本語では和語にも使われ、外来語を除いてほとんどの語に使うことができる。煙草(タバコ)や合羽(カッパ)、珈琲(コーヒー)など大航海時代以降にヨーロッパから入った語彙には、外来語であるにもかかわらず漢字が使われるものがある。
And told o3 to rewrite it in the new system it just created: gendai◊| ni okeru nihongo◊‿ no ippan-teki na hyōkihō◊‿ wa kanji▢| kana▢| majiri bun▢| de ari, kanji▢| to hiragana▢| (mukashi no hōrei▢| nado de wa katakana▢|) o majete hyōki◊‿ suru. kanji▢| wa jisshitsu-teki na imi◊• o arawasu go◊‿ ni tsukaware, hiragana▢| wa omo ni katsuyō-gobi◊‿ ya joshi◊‿ ni tsukawareru. chōsengo◊‿ nado de wa kanji▢| ga shutoshite ji-on go◊‿ ni shika tsukawarenai no ni taishi, nihongo◊‿ de wa wago◊‿ ni mo tsukaware, gairaigo◊‿ o nozoite hotondo no go◊‿ ni tsukau koto◊‿ ga dekiru. tabako⬢• (tabako) ya kappa▢– (kappa), kōhī×▢ (kōhī) nado dai-kōkai-jidai◊| ikō ni Yōroppa⬢| kara haitta goi◊‿ ni wa, gairaigo◊‿ de aru ni mo kakawarazu kanji▢| ga tsukawareru mono◊‿ ga aru.
It's pretty readable, and takes care of the homophone ambiguities (remaining ambiguities can be resolved through context). It also naturally resolves onyomi and kunyomi. Add italics and punctuation, and katakana is replaced.(of course, it's incorrect in parts... because LLM)
But the idea has legs. It will probably not replace Kanji due to cultural inertia, but this could a kind of shorthand especially for handwriting.
I'm pretty impressed! o3 just invented something new. It combined romaji and a tag system that it hallucinated to design a new Japanese orthography. As far as I can tell (I could be wrong), something of this nature has not been done before.

I've decided to release an MVP so I can gauge interest, and after ~8 months of deployment and 2 releases there has been some great feedback. It's definitely a much much bigger and more complex project than I originally anticipated though!
At the moment I paused new sign ups as it's not scaling up nicely, so I'm now refactoring the services to use async / message queue for the heavy Python tasks using Celery / RabbitMQ.
It was quite difficult to get the product in front of people that might interested and even though I found enough users to test and give feedback, it's been tough to find them. So my strategy now is to try and release blog posts on my architecture, approaches, pros/cons, etc, and build in public regularly. This takes away time from the actual development but hopefully I'll have a big enough community that I can tap into for testers when the new release is out.
I'm not posting a link to the project or even mention the name as I got a shadow-ban in Reddit when I posted a summary to my MVP post-mortem (no link) and now I'm terrified!
I'd appreciate any suggestions / different approaches you might have in terms of reaching more users!
