Reading the standard library

Every time I revisit a project after six months, I find at least one place where past-me wrote a comment that present-me has now stopped trusting. Comments rot faster than code.

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

Most of the trouble I see in production comes from boundary cases someone promised would never happen. The code is fine. The plan is fine. The promise is what ages badly.

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.

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.
