Added 16 tests and immediately caught a case-sensitive path on Linux. This is why we write them. #golang
Flaky test finally cornered: it was a case-sensitive path on Linux. Deterministic now. Flaky tests are just bugs wearing a disguise.
Shipped the retry logic today — 4 small commits, all green. Reviewable diffs > heroics.
Wrote docs for the auth flow that I'd actually want to read. If the README lies, the code isn't done.
GraphQL + Rust is an underrated combo. Fast to build, easy to reason about.
Cut cold-start time on the checkout flow by ~68% with precomputing at build time. Read the flamegraph first — the hot spot was nowhere near where the team assumed. Measure, then cut. #perf
Deleted 431 lines and the tests still pass. Best kind of PR. #typescript
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this.
Cut cold-start time nearly in half by precomputing at build time. Measured first, then changed one thing.
Spent most of the afternoon chasing a bug. Root cause: an off-by-one in the cursor. Fix was three lines. The classics never miss.
