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…

500B Tokens Later: Letting AI Agents Decompile a First-Person Shooter

During the last 3 months, I spent some of my time and tokens decompiling a popular first-person shooter. The goal was not to reach a simple proof-of-concept state. Instead, we really wanted an accurate, stable and feature-complete recreation of the game. The avid reader of my blog might have noticed that I had previously written two posts that have since been removed. Everyone else might now be wondering which game I am talking about. To both of you I can only say that corporate America was here to ruin our fun.

The Lightbulb Computer

A new direction for computing: projecting information into the real world to augment it, with a device that combines a projector and computer vision in the shape of a large lightbulb.

Unikernels were hard. key word: were

Justin Cormack, who worked on MirageOS back in the day, called me at the pub to talk about why unikernels are coming back. The friction that made them hard is gone, the operating system is design debt, and if you care about security you should seriously consider them.

Why DuckDB 2.0 is faster

DuckDB 2.0 alpha vs 1.5.5 on one laptop: recursive CTEs up to 90x, VARIANT 6x faster than JSON text, async I/O 2.4x on S3. What changes, and how to model data to get the speedup.

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
