Colophon

This site is built on a deliberately small stack chosen for longevity:

Layer Tool
Editor Obsidian — local-first, plain markdown
Storage .md files in a Git repo
Build ~5k lines of Rust, standard library only — no crates
Toolchain cargo for the build, uv for the test harness
Design Atkinson Hyperlegible Next and JetBrains Mono, self-hosted; colours checked for AAA contrast in light and dark
Hosting GitHub Pages
CI/CD GitHub Actions
Syndication RSS at /index.xml, JSON Feed at /feed.json
Webmentions webmention.io to receive, Bridgy and Bridgy Fed to syndicate

The architecture is spec + harness + replaceable build. The build code is small and can be rewritten in any language; what's permanent is the contract in spec/ and the test harness in tests/. See how-this-bliki-works for the day-to-day side and the repo's docs/adr/ for the reasoning.

Dates here use the Holocene calendar: the year plus 10,000, so 2026 is 12026. It's a small nod to the Long Now Foundation and to Kurzgesagt's Human Era, counting from roughly when people started building civilisation, about 12,000 years ago. Feeds and machine-readable dates stay in the usual calendar.

If every tool listed above disappeared tomorrow, the notes would still open in any text editor. That's the point.
