Writing

Notes on systems, networking, and how production actually behaves.

Observability, distributed systems, and the patterns behind the problems — written down while the details are still sharp.

  1. I thought logs were observability

    A pile of log lines can feel like seeing the system. It isn't. Observability is whether a UI can tell you what is sick, which machine, and since when — without grepping.

  2. Why I'm starting to write this down

    Four years at one company, a move to a startup, and the gap between using a system and being able to explain it.
