Cut CI runtime nearly in half by lazy-loading the module. Measured first, then changed one thing.
Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
If it's not in CI, it's not done. Relearned this the hard way again today. #golang
Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything.
Cut memory usage nearly in half by lazy-loading the module. Measured first, then changed one thing. #devops
The bug is almost always in the last place you changed. Relearned this the hard way again today.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
Flaky test finally cornered: it was a missing await. Deterministic now. Flaky tests are just bugs wearing a disguise. #typescript
Rewrote the hot path in Ruby. bundle size dropped noticeably. Read the flamegraph before touching anything.
GraphQL + Zig is an underrated combo. Fast to build, easy to reason about.
