   280x280 Massively Multiplayer chess (Desktop only)▲5

   Made this to try out o1-preview, took ~40 prompts and 3 hours in total, with a fairly solid backed written in Go. Works pretty badly in Firefox apparently due to canvas-canvas copies being really slow, Chrome works great tho. Doesn't work well on mobile yet, and has some other minor issues, but overall it feels incredible to put together something like this so quickly.

   Printing Chess Boards in a Terminal▲7

   I'm doing some fun chess-related programing during my sabbatical, and taking the opportunity to dive down rabbit holes I'd avoid for in a work setting. Found out interesting stuff from old ANSI DEC escape sequences to sixel graphics that are useful today.

    Hi HN, here is my humble weekend project. I couldn’t find any similar utilities online that would let me download all of my chess games, so I decided to make one. It’s definitely imperfect, so please let me know if you have any feedback!
