I launched the Corn Maze app for the Crow River Winery for 2026 (year 4) in September. There was no corn maze in 2025, but I’m happy to have it back this year.

TL;DR I turned the way I build talks into an Agent Skill on top of Slidev: story first, slides second, puns throughout. Code is on GitHub. Warning: it has zero tolerance for boring slides and a very…

I want to make it as easy to write a server for the 9P network file protocol as it is to write an HTTP server using frameworks like Flask or Express. Why 9P? Because Linux has native support for it,…

By that I mean open source software. Yes, there are problems in this golden age namely that the gold isn't flowing to all the most vital projects. We need a large amount of money to be taken from…

SeaBIOS is an open-source implementation of a 16-bit x86 BIOS. The name is a pun: it is a BIOS written in C (instead of the traditional assembly). It is the firmware that QEMU and KVM run by default,…

Of all the forms of tech debt, decoherence is the worst. It compounds exponentially with a system's rate of change, and AI is now producing it faster than ever, leading us deeper and deeper into the…

vLLM's TPU backend ran DeepSeek-V4-Flash only on TPU v7x. To bring it to v6e we decoded FP4 expert weights inside the Pallas grouped-matmul kernel with integer ops and fixed a prefix-caching crash.…
