Every week, what's new and useful - from building software to thinking like an engineer.

There's a interview question of the week — a real engineering question to test yourself against — solutions and common mistakes in the following issue.

There's a engineering war stories — what actually breaks in production — race conditions, schema decisions that don't scale, integrations that fail silently — and how it got fixed.

There's a systems thinking — trade-offs behind system design, database design, and scaling decisions — the choices that look fine until real load hits them.

There's a career notes — lessons on growing from mid-level to senior — code reviews, mentoring, and the judgment calls that don't show up in tutorials.
