A Proclamation Regarding the Restoration of the Em-Dash
Posted on Fri 26 December 2025 WHEREAS, the em—dash (—) has long served as the elegant scaffolding of the English sentence, providing the necessary breadth for parenthetical thought, sudden turns of phrase, and rhythmic pause; WHEREAS, a modern and unfounded prejudice has arisen, wherein the presence of the em—dash is viewed with suspicion and cited as […]
How uv got so fast
uv installs packages faster than pip by an order of magnitude. The usual explanation is “it’s written in Rust.” That’s true, but it doesn’t explain much. Plenty of tools are written in Rust without being notably fast. The interesting question is what design decisions made the difference. Charlie Marsh’s Jane Street talk and a Xebia […]
Experts Explore New Mushroom Which Causes Fairytale-Like Hallucinations
By Colin Domnauer Picture this: You’re enjoying a delicious bowl of mushroom soup, when suddenly you notice hundreds of tiny people dressed in cartoonish clothing marching across your tablecloth, jumping into your bowl, swimming around, and clinging to your spoon as you lift it for another taste.

Steve wants us to make the Macintosh boot faster
We always thought of the Macintosh as a fast computer, since its 68000 microprocessor was effectively 10 times faster than an Apple II, but our Achilles heel was the floppy disk. We had limited RAM, so it was often necessary to load data from the floppy, but there we were no faster than an Apple […]
LearnixOS
”If you can’t explain it simply, you don’t understand it well enough.” – Albert Einstein Hello there!1 In this book we are going to write and learn about operating systems together! We are going to implement an entire POSIX compliant OS in Rust and not use ANY2 external libraries. All of the thought process, code […]
Ask HN: What did you read in 2025?
Getting into reading again this year after a long break. The most memorable read of this year was ”The Count of Monte Cristo” (1846) by Alexander Dumas . It’s one of the greatest stories ever told. It’s ~1250 pages but I sped through it in 3 weeks even if I’m a slow reader. Highly recommended! […]

Everyone already knows how to use it. Package managers keep falling for this. And it keeps not working out. Cargo The crates.io index […]
