✨ Read this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: December 12, 2025 nullprogram.com/blog/2025/12/12/ Back in 2017 I wrote about a technique for creating closures in C using JIT-compiled wrapper. It’s neat, though rarely necessary in real programs, so I don’t think about it often. I applied it to qsort, which sadly accepts no context pointer.

Shaney Junior at github.com/susam/mvs. It is a minimal implementation of a Markov text generator inspired by the legendary Mark V. Shaney program from the 1980s. If you don't know about Mark V.
