This site. A blog about low-level systems programming, built with Hugo, self-hosted, running on a theme I wrote instead of one I downloaded.
I write here because explaining something is how I find out whether I understood it. Most posts began as notes for myself and only became posts once they were worth reading twice.
What is on it #
The longer material comes in series. One is about optimising an SPH simulation: compiler flags, SIMD, reading the generated assembly, and benchmarking carefully enough that the numbers say something. Another covers x86-64 boot protocols and came out of the work on OS-R.
The theme is hand-built. Three columns, a light and a dark palette sharing one set of tokens, and syntax highlighting that switches with the rest of the page rather than shipping a stylesheet per theme.
