I wish you the best in the Offline

A handful of people I follow and know about have announced their recent departure. Not from a job (although plenty of that going around), but from social media, AI usage, or in more extreme cases the Internet entirely.

Nix wrote half of my debugger

A few days ago I wrote about Rewind VM, a deterministic VM where every run of a Nix build is a pure function of its inputs, thread schedule included! I have been using it to find, reproduce and solve numerous race conditions in Nix builds, but it’s been making me feel a little crazy. What is this superpower, and why is nobody else using it? The tool has quickly grown a source panel, stack frames, bookmarks, a “Compare” tab, a lot more gdb support, thread lanes, which show who held the CPU at every step, and “Check from here”, which…

Retrofitting language models to operate over bytes

Recent advances in artificial intelligence (AI) have largely been driven by large language models, deep neural networks that operate over discrete units called tokens. To represent text, most large language models use words or word fragments as the tokens, known as subword tokenization1. Subword tokenization obscures fine-grained information, which is problematic, especially for scientific data—such as computer code or biological sequences—where meaning depends on the individual characters or bytes2. Models that instead operate directly on the byte encoding of text avoid these limitations, but until now they have lagged behind subword-based models in performance. Here we introduce a general method for creating byte-level large language mode
