Turning my Unihertz Jelly Star into an Xperia Play like device. Basically I want to add a slide up controller to this tiny phone. I was reminded of my Gameboy Micro while watching a review of Mina the Hollower on it and now I'm determined to play that game on this tiny thing. No idea if it will actually run.

Learning FreeCAD to create a sliding insert between the body of the phone and the screen. If I can pull that off the rest should be easy.

Unfortunately the controller board will have to connect to the phone over BT although it will use the phone's battery. I wanted to connect it over USB internally but there's no bus on this phone and trying to hijack the lines running to the USB C port would be feature creep that would stop the project. Another idea was to take over an I2C line going to some peripheral I don't care about but I think that would require a custom android kernel so BT it is.

By the way this phone is awesome. Highly recommend for anyone who wishes they didn't need to carry a smart phone.

Building a map guessing game where you're given a map with the labels/axis redacted, and then you have to guess what it's a map of. e.g. the map would be average height by country, but you would just get a map where countries like The Netherlands were the darkest, and then you'd have to try and figure out that it's average height!

The hinting system for it is a bit work in progress (trying to tune the difficulty and feedback from hints)

A statically typed s-expression language for dotnet (called bjolang. Because I made it), with fast Rrb vectors and champ maps. No object system, but a trait system with associated types. The looping system is inspired by my own hygienic looping system for guile scheme ( https://rikspucko.koketteriet.se/bjoli/goof-loop )

It is really really fun, but I have no idea what I am doing.

I really dislike async and will hast asyncheonisity behind coroutines (which sadly will be botched because dotnet). i will use them to implement concurrentML sometime in the future. Not unlike go, but the will be called bjoroutines and soaened with the "bjo" keyword.

Other than that, it is pretty standard hindley Milner, but with some limitations to make parallel compilation simpler.

Edit: och: and i will make comprehensions general. (summing (in-vec my-vec)) Or (folding #(+ % a b) :for a (in-list aList) :for b (in-generstor a-generator))

AI agent deployments are happening completely automated nowadays, One command and there it is your agent is live. Recent news about AI agents cost explosions, more than estimated token usage has got me thinking, These are all detected post deployment, pre deployment, are the teams thinking this? Are they even considering who is responsible for what in case of an endless loop being executed that slowly raising the hidden costs.

Introducing - https://release-gate.com/

A pre deployment checker for AI agents that sits in your CI/CD pipeline, No infra required, just a python environment and you are ready to roll.

PS: Comments and suggestions most welcome!!!
