One of them is its Lua plugin system, which lets you write custom wrappers for programs that aren’t compilers in the traditional sense. With Bug 2027655 now merged, we can use this to cache Firefox’s WebIDL…
Evolution of a self-hosting hobby: from clueless to amateur.
Similar to the previous post, this post covers my analysis of a benchmark on RISC-V targets. Unlike the previous post, I was able to land a patch to eliminate the performance gap to GCC (for this benchmark)!

At Photon, we are developing the world’s most complete iMessage API (with RCS and SMS fallback) for agents: infrastructure that lets Agents reliably communicate through one of the most native messaging interfaces people already use. While building it, we run Mac-backed systems continuously and care a lot about making…
I never understood how traceroute discovers each hop. Turns out it's a clever TTL trick, and about 80 lines of Rust.
Karpathy recently posted about using LLMs to build personal knowledge bases — collecting raw sources into a directory, having an LLM “compile” them into a wiki of interlinked markdown …

Before we explore FreeBSD jails, it is worth refreshing our understanding of how Linux solved the same problem with LXC (Linux Containers).
Many people know, or have heard of, the Motorola 68000 architecture. These processors have been used in many machines: in the first generations of Apple Macintosh computers, in the ever-rivals Amiga and Atari ST home computers, in many workstations built by Sun , HP and NeXT (to name only a few), but also in many…
After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear. I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even…
David Schütz's bug bounty writeups
A while ago I wrote a small file watcher in Go for my own use with an accompanying blog post . I needed a tool that I could just plop in front of the command I was running as part of my iteration loop. I use it for recompiling C files when I modify them,
