Just Ask
Ask me anything about software architecture, careers, PHP, Go and the craft of building software; I answer here, in the open, for everyone.
Whatever's on your mind, don't hold back. Questions reach me directly; I answer the good ones and publish them on this page. Your email is never published.
Move to `errgroup.WithContext` with a request-level timeout on top and thread ctx into every HTTP and DB call; an ignored ctx means no cancellation at all.
Use `chunkById()` when there is real per-row work and never touch the cursor column; if you only update a column, switch to one set-based `UPDATE`.
A readonly withX returns a new instance: `new self` with named arguments is portable, and `clone($this, [...])` fits PHP 8.5 when validation is simple.
Take an ownerless org-level problem, lay the solution out in a written tech strategy, and show impact through the teams you accelerate, not your commits.
Generate the ID as a W3C `traceparent`, carry it in an SQS message attribute rather than the body, and inject it with the OTel propagator on both sides.
Pin the user with a build-time `ARG UID`, use `COPY --chown`, and for named volumes chown only `storage` and `bootstrap/cache` in the entrypoint.
Go contract-first with `openapi.yaml` as the single source of truth; what ends drift isn't the direction you pick but a green contract test running in CI.
Build the partial index on `WHERE status='pending'`, include the `ORDER BY` column, pair it with `FOR UPDATE SKIP LOCKED`, and pass 'pending' literally.
Cancellation propagates only if you pass `r.Context()` into every downstream call, leave no `context.Background()` in the chain, and use `WithoutCancel`.
Integer cents in the DB, an immutable `Money` on the model: put the mapping in one `CastsAttributes` class and keep currency as a second column there.
