Stay up to date with practical insights on backend engineering, system design, and building reliable software.
Connection leaks cause pool exhaustion, which causes request timeouts, which causes cascading failures. They're subtle because the connection appears to be in use — it's just never returned. Here is how they form and how to find them before they take down a service.
Read moreMost Dockerfiles copy the entire project directory into the image without a second thought. That decision bloats your image, leaks sensitive files, and slows every build — and a .dockerignore file is only part of the fix.
Read moreMost Docker configuration bugs — wrong users, missing volumes, read-only filesystem failures, resource limit mismatches — are discoverable before production if you know what to test and how. A structured local validation process catches the class of issues that only appear at runtime.
Read moreThe builder pattern solves real problems with telescoping constructors and optional parameters. It also introduces indirection, deferred validation, and maintenance overhead that aren't always worth the tradeoff.
Read moreAsking questions in technical settings is consistently underrated and under-practiced. The engineers who ask the most specific questions understand systems more deeply, build better things, and catch more problems before they ship.
