There's no universal winner. Barman wins on simplicity and real-time WAL streaming with low operational overhead. pgBackRest wins on volume and restore speed. The criteria matter more than the tool.

Kubernetes technical interviews have a problem nobody names: they ask about objects you'll never touch in production, while ignoring the mistakes that actually break real systems. Here's the map I was missing.

A HN thread with 398 points blew up the debate again: is Docker Compose in production legitimate or an antipattern? I ran my real stack on Railway for 30 days and brought actual numbers. Spoiler: it's not embarrassing if you know exactly what it costs you.
