Three log lines that saved an outage

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

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.

I trust monorepos more in the second year than I did in the first. Most of the early friction goes away once the tooling catches up.

I split a 4000-line file into 12 smaller ones this week. The smaller files weren't actually easier to understand. The 4000-line file was a problem of structure, not of length.

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

I keep a small log of decisions in a text file. Not architectural — just small ones. "Picked X over Y because Z." Future me reads it more than I thought he would.
