Why Lisp/Clojure?Sat, 01 Aug 2026 14:55:31 +1000clj-rsshttps://b12n.net/posts-output/2026-08-01-the-review-that-caught-what-the-reviews-missed/https://b12n.net/posts-output/2026-08-01-the-review-that-caught-what-the-reviews-missed/Three tasks, each with its own tests, each individually reviewed and approved. Then one more review looked at the whole thing at once and found two real bugs that none of the three approvals had caught. Then the review that checked the fix found a smaller fourth thing.b12n-publish is the pipeline behind this blog: it watches a handful of repos for activity worth writing about, gets a real draft from a real model call, and only after a human reads and substantially revises it does anything get published. Building the pipeline itself happens in a specific shape. Write a plan that breaks a feature into a handful of independently testable tasks. Work through the plan one task at a time, and give each task a fresh implementer with no memory of the tasks before it, just the plan and the one piece it's responsible for, plus its own dedicated reviewer before the next task starts. The bet is that a narrow, well-defined job catches things that accumulated context and creeping scope would let slide. Once every task is done and individually approved, one more review looks at the finished result as a single, whole change, not a task at a time.Sat, 01 Aug 2026 00:00:00 +1000https://b12n.net/posts-output/2026-07-31-174-commits-in-a-math-education-tool/https://b12n.net/posts-output/2026-07-31-174-commits-in-a-math-education-tool/Most side projects never get past the scaffold. This one has 174 commits and counting: a curriculum API, a web SPA, a native mobile app built with ClojureDart/Flutter, gated authentication with three login paths, a SQLite-backed store, and a production deployment behind nginx. That's not a stub. That's a system that's been lived in.I want to zoom into the part of the system that's easiest to relate to if you've ever tried to teach or learn math on a screen: getting the content to render correctly. Turns out that "just typeset the math" is a much longer road than it sounds.Fri, 31 Jul 2026 00:00:00 +1000https://b12n.net/posts-output/2026-07-31-mermaid-diagrams-in-cryogen/https://b12n.net/posts-output/2026-07-31-mermaid-diagrams-in-cryogen/This blog now renders Mermaid diagrams from ordinary fenced code blocks.
