Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything. #rustlang
Added 19 tests and immediately caught a truthy check on 0. This is why we write them.
Reviewed a PR that touched pagination — left 3 comments, learned two things myself. Reviews go both ways.
Profile before you optimize — every time. Relearned this the hard way again today.
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this. #rustlang
Spent most of the afternoon chasing a bug. Root cause: a float rounding edge case. Fix was a one-line fix. The classics never miss.
Wrote docs for streaming responses that I'd actually want to read. If the README lies, the code isn't done. #testing
Deleted 127 lines and the tests still pass. Best kind of PR.
Added 15 tests and immediately caught a float rounding edge case. This is why we write them.
Flaky test finally cornered: it was an off-by-one in the cursor. Deterministic now. Flaky tests are just bugs wearing a disguise.
