Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output.

On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte).

It's pretty slow right now (roughly 20–30 minutes of training and 45 minutes each for compression and decompression on my AMD 7800XT).

Using purely open source alternatives, nanogram provides a robust and small way to emulate the old days of Instagram where friends could share moments with each other without all the fluff.

Also included is the ability to play Scrabble, connect 4, and chess with your friends.

The platform is invite only meaning the server operator must generate a invite token to allow new users.

Because of the global power of Tor, hosting is completely free and E2EE encrypted as it operates as a onion service.

It was so fun to see how many different actions I could squeeze into a single button. I fleshed it out with as many screens of level as I could squeeze into pico8's tiny constraints, and polished it as well as I could.

It certainly has a bit of a learning curve, but I think it turned out pretty well all things considered. The entire project took about three weeks, including code, pixel art, and music. I'm really pleased with pico8's built-in editor and some smart choices in the music tracker. It's limited, but the tools I really needed are all in there.
