Chipmunk'd versions of songs on Youtube: https://www.youtube.com/@ChipmunkEstudio Taking song requests!

Reminds me of the classic Sludgefest [0]. (For the uninitiated it's a collection of Chipmunks records slowed until the voices sound roughly human.)

This weekend I've been going through a bunch of stuff with A2A, building little samples and just getting my head around it. Threw together this repo[1] with a bunch of the stuff I'm doing, if anybody else is interested.

Also, watching a bunch of videos and reading docs on OpenClaw. I had thought I'd do an install of it sometime this weekend, but I don't know if I'll get to that at this point or not.

And lastly, messing with Spring AI[2]. I wanted to get a local build of that going so I can dig into the bowels of it and hack on it a bit. So I got that repo cloned and ran a quick build, and now I plan to start exploring the codebase.

A couple different projects. I've been cataloging and publishing my vintage ad collection at https://adretro.com. It's starting to get a lot of organic traffic after about a year online, which is cool.

I'm also working on a new strength gains-tracking app that is a lot more intuitive, motivating and friend first. I've been using it with some friends for the last 10 weeks and everyone making is consistent gains. It is my first full PWA, vanillaJs, backend is Lucee & MySQL. Works great on iOS and Android, no one has any complaints. The web stack has come a long way I am probably not going to do a native mobile app for a while. I'll probably make it public in a couple weeks.

Helping out with a freelance project I built 15 years ago. It didn’t end on the best of terms, but the relationship has since been repaired (and I’m much better at managing my time now)

It’s been fun to come back to, most of the code I wrote still drives the business (it’s just far outdated).

I was pretty early on in my career when I wrote it, so seeing my mistakes and all the potential areas to improve has been very interesting. It’s like buying back your old high school Camaro that you used to wrench on.

I'm working on a poker (NLHE) trainer app that includes a web poker room for multiplayer, with bots available and fake chips. Using Event Sourcing with some CQRS in Elixir and Phoenix. The player view is a projection of House Events, suitable for hand history, for feeding to solvers or LLMs for real time advice or post hoc analysis.

The idea is to get tons of reps in, across varied situations, with excellent advice to build good intuitions and decision making abilities. Or to stop making bad or terrible decisions. Or just play poker for free.

I'd like to monetize with at least the hand history format open sourced. Ping me if you would like to get involved with GTM and the revenue side of things.
