I made an RSS reader with social features based on AT Proto (repost articles / star them). Trying to fix the web and the depressive social medias.

Been working on a note-based (rather than audio-based) AI music generator. Still very limited, perhaps I launched too early; it only generates somewhat generic melodies at the moment. Working on generating more interesting accompaniment tracks now, plan to then return to melody and adding some "style" settings.

I've been building my own IDE that works the way do (and those in my social circles/professional life do). It allows for use of multiple agent harnesses (i.e claude code, codex, pi, opencode), and makes worktrees much easier to work with. Also has its own code review workflow. My coworkers and several friends have all started using it now. Its been an absolute blast to build, and has definitely increased our productivity vs VS Code, Zed, or Cursor.

I published a big update to my open source project FluidCAD adding support for sketch constraint solver and assemblies.

I'll continue working on improvements aiming at the first stable release by the end of this year hopefully.

My wife and I made a daily guessing game together. Unlike others of the genre that we enjoy playing, an explicit goal of this one is teaching you about the world as you play it. It’s quite simple, using Wikipedia and factbook.json for information about the countries, but it incorporates a few ideas that I think are fun and there’s a lot I’d like to experiment with.

I built this sql formatter <https://sql.leuduan.work> for my own use - it works by parsing the SQL query to AST using native engines where possible (for BigQuery it use GoogleSQL library, for MSSQL it uses Microsoft ScriptDOM, the rest uses Apache Data Fusion Parser) and from the AST it re-generates the SQL query in a consistent formatted style. You can throw in all kind of badly formatted SQL queries and it will work just fine. Hope you find it useful!

https://spark.enverge.ai/ a growing platform of nano data centres, focused on "the rest of us". Very light-weight virtualisation layer, great for Grace-Blackwell experiments and general benchmarking.

Using a local model (qwen 3.8 27b) to evaluate and tag public domain images from US national parks to find the best landscapes.

They are sorted by predicted aesthetic rating and can be filtered by time of day, color, orientation, and park.

years ago i sat through interviews for front end & back end engineering roles at my old job while other folks were out (as member of a panel), and consistently I found that where we gave some real bugs to debug & fix, through a shared IDE, then worked together to solve it or go over the persons thinking, those situations we absolutely always got a better sense of how the person worked and solved problems & whether we'd like working with them or not (to some degree). I also found a few of those exercises to be educational myself.

this year i thought itd be great to help prepare myself and other people in the job market with a tool that presented broken front end code, and then allow debugging on the browser and patch code right there, to test if it worked or not. if cant solve it, theres a nice explainer popup. my main hope is to help level up interview code chops and confidence in debugging just like we would on a real production system , at least the simpler bugs.

still working on it, here's the draft of the idea: https://bugcloud.app

Been working on terminal API client that uses .http file as source-of-truth. It's more like API-as-a-code then similar tools like Postman, Bruno or Yaak. Supports gRPC, graphQL, websockets, SSE, local mocks, SSH/k8s etc.
