I'm teaching myself category theory, I'll kick back off a local trail, keep notes on the birds I see and read and do the problems in my notebooks. I've got Basic Category Theory by Leinster, and How to Read and Do Proofs by Solow as my references, notebook, pen and a pair of Nikon binoculars.

Can I ask what prerequisite mathematics you would need to know before reading those? I'm really interested in that topic and better understanding functional programming.

I'm working on a WASM clone of the original Castle Wolfenstein. I'm going to call it Castle WASMstein.

Please keep posting updates about this because if I could instantly fire up a game in my browser, I would definitely pay for that and play with it all day!

I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand

Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).

In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession

A midi sequencer, which does or is supposed to do what you expect.

In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.

It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
