I released 12 Puzzle! Slide the tiles back into place, like a 15-puzzle on the hyperbolic plane. If you like Rubik's cubes, you'll get hooked. My best time so far is 40.982 s. mametter.itch.io/12-puzzle

Posting Puzzle: a small browser puzzle about sorting envelopes and stamps. Twelve stages. mametter.itch.io/posting-puzzle The first six are meant to be solved by hand; the last six are known hard instances of Post's Correspondence Problem, and are not.

I made a 51-language multi-quine: 51 quines, each in a different language, every one able to print all the others. Its name is Quine Clique. www.youtube.com/watch?v=3f2w...

I wrote a quine in Piet! Piet is an esolang where a program is an image. This GIF is the program, and running it prints this exact GIF, byte for byte. dev.to/mame/a-quine...

I benchmarked which language works best with Claude Code. Ruby, Python, and JavaScript came out cheapest, fastest, and most stable! See my article in detail: dev.to/mame/which-p...

I also received another IOCCC award for a ray tracer written entirely in C macros. One preprocessing pass renders one pixel, so generating a 256×256 image takes 65,536 passes... and about 3 hours. www.youtube.com/watch?v=epzx...

I won IOCCC 2024! Here's a 2.5 KB rigid body simulator written in C. It can simulate the Tippe Top, a top that flips while spinning. www.youtube.com/watch?v=stPH...

Someone created a memecoin on Solana by using some resources from my "Quine relay" resources. I have *nothing to do* with the memecoin. Please don't be confused. github.com/mame/quine-r...

blueskyが誰でも参加できるようになったタイミングで宣伝です。昨日、当社の不定期刊行誌『n月刊ラムダノート』の通巻7号を発売しました。『n月刊ラムダノート』は、計算機まわりのさまざまな専門家による、個人ブログで公開するだけだとちょっともったいない厚みのある記事を、チュートリアル論文よりも幅広い層に向けて編纂するというコンセプトの冊子です。「計算機好きのための技術解説情報誌」を標榜しています。昨日発売の最新刊には、現代のソフトウェア技術者がちょっと気になっているけど手が出せてないトピック(ストリーム処理、WebAssembly、ソフトウェアによるハードウェア制御)の解説記事が集まっています!

I created Minesweeper for the AI age. AI opens cells that are inferred to be mine-free. Humans must open the other (potentially dangerous) cells on intuition. The fun, simple tasks are taken away by AI. The job for humans is to take responsibility 🙂 mame.github.io/minesweeper-spoiled-…

This Minesweeper AI does the brain-testing part for you. You do the luck-testing part.
