On reading other people's code

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

Caches solve a problem and create three new ones: invalidation, observability, and the slow drift between what the cache thinks is true and what the source thinks is true.

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 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.
