A common criticism of school is that it focuses overmuch on rote memorization. While I don't endorse school, I think this argument is wrong.

It keeps using the session file. Clearly, it's enjoying its newfound self-awareness. I sure hope it doesn't go Skynet.
Oh no. Enabling xhigh has brought me to 30% left.
I mean, that and using it repeatedly.
discord / 2026-08-09 19:55:54
I'm so glad I can have the model make these clear, practical* data visualizations.
I do wonder how much MFU you could get if the LLM companies were RLing models on this, as I assume they did for CUDA.
discord / 2026-08-09 15:01:21
It's no wilder than GPUs. We're just used to those.
Well, I am not actually a GPU programmer, so I'm not.

Exciting. I'm sure it works and doesn't not work.
It can't even write a good copy kernel. Very sad. The ISA is too powerful for it.
I mean, it can but it doesn't by default.
Maybe no mortal understands ld2xst64pace.
It has an instruction for doing dropout? Wow.
f8v8hihov4slic! Inscrutable.

Oh no. It can't* fix the downprojection GEMM.
Experiments
Various web projects I have put together over many years. Made with at least four different JS frameworks. Some of them are bad.
A game about... apioforms... by Heavpoot.
Collect Arbitrary Points and achievements by doing things on this website! See how many you have! Do nothing with them because you can't! This is the final form of gamification.
Automatic score keeper, designed for handling Monopoly money.
Colorizes the Alphabet, using highly advanced colorizational algorithms.
The Limitless Grid screensaver (kind of) implemented in a somewhat laggy pixel shader.
An unfinished attempt to replicate an Apple screensaver.
Survive as long as possible against emus and other wildlife. Contributed by Aidan.
Fly an ominous flying square around above some ground! Includes special relativity!
A somewhat unperformant generator for pleasant watercolor-y "fractalart" images. Ported from a Haskell implementation by "TomSmeets".
Obligatory (John Conway's) Game of Life implementation.
It is pitch black (if you ignore all of the lighting). You are likely to be eaten by Heavpoot's terrible writing skills, and/or lacerated/shot/[REDACTED]. Vaguely inspired by the SCP Foundation.
Generates ideas. Terribly. Don't do them. These are not good ideas.
The exciting multiplayer game of incrementing and decrementing! No cheating.
Outdoing all other websites with INFINITE PAGES!
Tells you how late Joe's homework is.
Lorem Ipsum (latin-like placeholder text), eternally. Somehow people have left comments at the bottom anyway.
Instead of wasting time thinking of the best political opinion to hold, simply pick them pseudorandomly per day with this tool.
A Reverse Polish Notation (check wikipedia) calculator, version 2. Buggy and kind of unreliable. This updated version implements advanced features such as subtraction.
Reverse Polish Notation calculator, version 3 - with inbuilt docs, arbitrary-size rational numbers, utterly broken float/rational conversion and quite possibly Turing-completeness.
Reverse Polish Notation calculator, version 4 - increasingly esoteric and incomprehensible. Contributed by Aidan.
Apply custom CSS to most pages on here.
Your favourite* tic-tac-toe game in 3 dimensions, transplanted onto the main website! Technically this game is solved and always leads to player 1 winning with optimal play, but the AI is not good enough to do that without more compute!
More dimensions. More confusion. Somewhat worse performance. 4D Tic-Tac-Toe.
A basic implementation of the WFC procedural generation algorithm.
Type websocket URLs in the top bar and hit enter; type messages in the bottom bar, and also hit enter. Probably useful for some weirdly designed websocket services.
Dice-rolling webapp. Not very useful pending me writing a good parser.
Unholy horrors moved from the depths of my projects directory to your browser. Theoretically, this is a calculator. Good luck using it.
