A civilization clone, but going way deeper than is reasonable (inspired by dwarf fortress). I'm currently building the geophysics simulation that will allow for realistic terrain generation, powered by actual mantle convection and plate tectonics. Once this is finished, then an actual per-cell atmospheric and oceanic model. This should keep me entertained for at least a year, at which point I can start working on the actual gameplay part of things.

I (w/ Claude) have built a framework for writing neural networks in Lean 4 that compiles to StableHLO MLIR and runs on GPU via IREE.

The last couple weeks have been working on a parking spot app for Taipei and New Taipei. Finding a available spot, especially during weekends is very difficult. There are some apps, but only in Mandarin, so I did a English version.

If you are in the area, try it out https://taipeiparking.com/ - Android app and web app.

I’m currently working on an API-first identity verification backend built with FastAPI. It is made for handling ID documents, selfies, OCR data, biometric signals, API keys, webhooks, and tenant billing data.

Hopefully I can find an investor in the future, still in the early stages.

Nothing fancy, I want to design a way to compact A.I context during runtime, using R.P.I semantics (research, plan, implement)

I know some Rust, was going about it with clap, but no one I know cares about Rust so I've switched to Golang with spf13 Cobra cli

Harness is pretty cool, but I'm still a quite noob gopher, so I'm taking the chance to learn the ins and outs of Go...

No A.I touches my code lol, else I would learn jack shit

if you’re not too locked into it (you’re not if you have CC), i’d recommend you check out urfave/cli.

https://repowarden.dev - feel fairly feature complete now and am dogfooding heavily so it’s time to face my fears and do some “marketing” and “sales”. Whatever that means.

I started a new software defined automation project. I wanted something that I could just open a webpage and start writing code that could just be uploaded and ran instantly. I picked an ESP32-P4 for the first hardware. It’s MIT licensed and has a git repo that I put up this morning https://github.com/OpenPiLab/pilab-esp32-p4-plc

I think LLMs will make dealing with complicated ERPs much simpler. So I built a chat-native one that can do all the functionality just via prompting: https://github.com/lambdadevelopment/lambda-erp

For occasions like birthdays or Christmas where people want to give you gifts, I have always wanted to ask them to make donations to charities of my choosing instead. So I built an app to enable this: http://donateyourgift.com/ It is very simple but I didn't find anything quite singly-focused like it, so I built it just to scratch my own itch.

Agent engineer master. Currently it's a skill builder to generate custom production grade skills for agents but my goal is to build it into a system that non engineers can use to build and deploy agents with just prompting. https://agentengineermaster.com/
