https://b12n.net/Why I do what I do. Why Lisp/Clojure?Thu, 27 Aug 2026 12:45:57 +1000clj-rsshttps://b12n.net/posts-output/2026-08-27-three-clojures-one-c-library/https://b12n.net/posts-output/2026-08-27-three-clojures-one-c-library/Three suites of raylib examples, written in three different Clojures, calling the same C game library. 97 examples in Jolt on Chez Scheme, 212 in jank through C++/LLVM, and 113 in JVM Clojure over Project Panama. That is 422 programs doing roughly the same kinds of things, and the interesting part is where each one puts the boundary between Lisp and C.raylib is a good library to pick a fight with here. It is plain C, it is small enough to read, and it passes structs by value almost everywhere. That last habit is comfortable in C and awkward in most foreign-function interfaces, so the three suites end up disagreeing in ways that show you exactly what each runtime is doing underneath.Thu, 27 Aug 2026 00:00:00 +1000https://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 bugs that none of the three approvals had caught. The review that checked the fix turned up 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 draft out of a model call, and publishes nothing until a human has read and substantially revised it. Building the pipeline itself follows a fixed shape. A plan breaks a feature into a handful of independently testable tasks, and each task goes to a fresh implementer with no memory of the tasks before it, carrying only the plan and the one piece it owns. Every task gets its own reviewer before the next one starts. A narrow, well-defined job should catch what accumulated context and creeping scope would let slide. That is the bet, anyway. Once every task is done and approved, one more review reads the finished result as a single whole change.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. It has 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.
