Zig's new CLI progress bar explained

New CLI Progress Bar Explained Sometimes, programming projects are too easy and boring. Sometimes, they're too hard, never ending or producing subpar results.

This past week I had the pleasure of completing a project that felt like maximum difficulty - only possible because I am at the top of my game, using a programming language designed for making perfect software. Before this feature was even merged into master branch, it led to discovery, diagnosis, and resolution of a subtle bug that has hidden in Zig's standard library child process spawning code for years. In most programming projects, a linear scan to find allocated objects is undesirable, however in this case 200 bytes for node parent indexes is practically free to iterate over since it's 4 cache lines total, and the only contention comes from actual updates that must be observed.
