Open-sourced my implementation of AlphaZero and various other MCTS policies to play Tetris. In contrast to other Tetris-agents, this implementation does *not* rely on observation- or action-space simplification. It trains an agent with the same information a human has.

🥳 50k score achieved, TetrisZero is working! Here's the viewer-site with a replay (actually, the replay became so long that the site is lagging a bit, lol). Full details on the algorithm will follow, once I evaluate it against AlphaZero...

Have you ever wondered if the Deutsche Bahn train you booked is typically on time?
Unfortunately, Deutsche Bahn offers no API for historical train delays.
That's why I built an app to collect and analyse it!

(okay - that sounds exaggerated, it's pretty much just an @obsidian.md clone I built in ~7 days)
Everything is local, no database; File > App!

Would anyone else be interested in an Anki Handheld?
Basically, a dumb device you can use to review flashcards.
Sync via Ankiweb, no editing, just 4 buttons for reviews.

My local supermarket introduced Cashierless Checkout a while ago.
It's great, and yet I almost never see people using it. Instead, the line at the regular checkout is as long as ever.
Why is are people not using it? Are people really that lazy? Or just scared of innovation?
