Notes

The most useful property of a small server is not cleverness. It is the ability to explain its current state in a few minutes.

A single timing result is tidy, persuasive, and usually incomplete. Useful measurements describe a distribution and the conditions around it.

Low light removes detail, but it also makes the structure of a place easier to see.

Good releases are rarely memorable. They are bounded, observable, and easy to reverse.

A useful status page answers what is affected, when it began, and when the next update will arrive.

A boring default is not an old choice. It is a choice with well-understood consequences and an easy escape route.
