Spent most of the afternoon chasing a bug. Root cause: a float rounding edge case. Fix was a single index. The classics never miss.
Reviewed a PR that touched the caching layer — left 6 comments, learned two things myself. Reviews go both ways.
Deleted 218 lines and the tests still pass. Best kind of PR. #perf
Cut memory usage nearly in half by streaming instead of buffering. Measured first, then changed one thing.
Kubernetes + Rust is an underrated combo. Fast to build, easy to reason about.
Rewrote the hot path in Rust. bundle size dropped noticeably. Read the flamegraph before touching anything.
TIL: SQLite handles way more concurrency than I assumed. How did I not know this.
Cut CI runtime nearly in half by precomputing at build time. Measured first, then changed one thing.
Migrated the caching layer from Next.js to Rails. Boring, reversible, no downtime. Exactly how I like it. #rustlang
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
