I'm working on fyai, a rather opinionated agent harness, built to work as a unix tool and the idea that eventually AI is going to be a commodity, where having control of your own data is what's important.

It is still quite alpha, but at a usable state.

The biggest technical difference between fyai and other harnesses is that in fyai the state is durable and stored in a disk deduplicated arena, which means that git like branching is free and storage requirements are very modest compared to JSONL/SQLite storage.

Latest additions has been full markdown/mermaid rendering support and (very alpha) Claude code and Codex session import.

https://bongbong.io BongBong tank shooter game. My first game. I wanted to recreate a game that is kind of a mix between old Battle City (NES) and Dyna Blaster, which I used to play as a kid in the 90s. I wanted to have a game where you don't just have retro graphics and beautiful explosions with realistic physics, but I also wanted to capture map building and playing with your friends - locally and online. I'm build…

Ha, love it.

I didn't really know the rules, but enjoyed protecting the frog.

I played a few games, and each time was protecting the frog. I wished I had a turn trying to kill the frog!

Cool idea - I forgot where I found it but there was a cute dragon Tamagotchi clone that I found for Arduino a few years ago. For ESP32 - recommend paying close attention to the FreeRtos, it's seriously powerful. Even if you are just using Arduino style code you can use it for background scheduling and interrupts (for your api and buttons for example), as well as dual core use on S3.

I’ll look into that, thanks! Right now I’m studying the Tamapoke[1] codebase, which should give me lots of ideas and help me get started. [1]: https://github.com/socquique/TamaPoke

If I remember correctly, the code base left a lot to be desired on the one I tried - it was fun but wasn't very adaptable. I'm sure you can do a better job

http://schoolholidays.deals/ A UK-based flight deals service aimed specifically at parents who can only travel during term-time. Having this issue myself now with two children whereby flight prices double going into school holiday season, I have always wanted some kind of service which alerts me of good deals. I still have a long way to refining the actual product, but trying to fit the development around work commit…

Brilliant brilliant idea

[HUMAN-CODE] I'm building a video game. It's part Valheim, part Ultima IV: https://stravaeger.com/ You can play the demo in the browser now (mobile as well as desktop), but I'll be packaging it up for Steam soon. It's all vanilla javascript, html and css. No AI, no 3rd party game engine, no build system even, and just a couple external dependencies for things like networking that I didn't want to reinvent myself. It'…

Your game is good bro, I think there is a real audience out there for this game.

ok, may I ask who are they ?

Please, yes. Half of the fun of being on HN was "Show HN: I made some random thing", which typically amounts to "look at what prompt I wrote" nowadays. I use agents every day, I'm not against it, but it completely changes the lens through which I view a project

But how would you know if someone was just lying when they added "[HUMAN-CODE]"?

People don't say when they vibe code things but it's still very obvious.

https://shopspec.io/

ShopSpec is a deterministic parametric furniture generator (bookshelves, cabinets, shop carts, leg-and-rail frames, multi-carcass composites) that encodes real woodworking intelligence and outputs shop-ready artifacts.

Most recently, introduced the concept of value engineering by sweeping across dimensions to batch evaluate candidates that ranks based on sheet purchases. Also have in beta an MCP connector to let agents explore the deterministic engine.

I'm building a number of items for home and shop and ShopSpec has been instrumental to plan, visualize, and execute on these new ideas/projects.

I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control. Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI…

The most likely outcome from a naive attempt to automate trading is random results.
