A short tour of /proc

The team I learned the most from didn't have great tools. They had a great habit of reading each other's pull requests in full, including the parts that weren't theirs.

There's a kind of premature optimization that comes from imagining a future team. "What if someone needs to swap this out?" Often, no one does.

Most retry logic I've removed turned out to be hiding a real bug. The retries made the failure invisible, and the bug compounded for months in the background.

Latency budgets work better than latency targets. Targets are aspirational. Budgets force you to delete features when you go over.

I write smaller commits than I used to. The commits are uglier in isolation and much easier to read in sequence.
