On giving talks I haven't given

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.

I used to add a layer of abstraction the first time I saw a pattern repeat. Now I wait for the third. The waiting is uncomfortable, but the abstractions that survive that wait tend to last.

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.

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