💥 Read this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: 🦔AI companies are bulk-buying rare books, scanning them through high-speed machines that cut the spines off, and shredding the originals. A service called ISBNdb facilitates orders of up to a million books and keeps buyers anonymous. Pre-2022 books are premium because they're free of AI-generated text. A federal judge ruled the practice is fair use because eliminating the original means only one copy exists at a time. Anthropic hired the former head of Google Books partnerships to obtain "all the books in the world." My…

The Bun rewrite seems well positioned as proof-positive that AI and specifically Anthropic’s AI can do the work of open-source maintainers, for some money, but faster. On the 8th of July 2026 Jarred Summner of Bun fame posted about “Rewriting Bun in Rust”. At the time, I felt pretty Canny, having already read about Anthropic’s C compiler and Cursor’s FastRender web browser. It seems like…

For reference, even with modern compression techniques like gzip -9, you can't compress this file below 85kB.In the 1970s, Douglas McIlroy faced this exact challenge while implementing the spell checker for Unix at AT&T. The constraints of the PDP-11 computer meant the entire dictionary needed to fit in just 64kB of RAM. A seemingly impossible task.Instead of relying on generic compression techniques, he took advantage of the properties…

Compromise is neither good nor bad, it’s something we do every day. It’s decision making. Prioritizing. Deciding that one thing is more important than another. It’s finding the right balance between two competing desires. Which compromises you make — that’s what matters. Choosing the right compromises is what defines good design. Companies like to tout products as “uncompromising” or having “no compromises”. That’s impossible. Once you decide on an approach, you inherently decide against other options. Another word for…

They offer the possibility of a type system capable of encoding and enforcing arbitrarily subtle invariants. The sort of thing that, in regular languages, ends up (at best) as a comment, and which quickly gets lost as the size of the team grows. Then you get subtle misunderstandings and components that don't quite fit together. It's often the case that those components have grown to a sufficient size that, when the…
