About

This is a notebook, not a magazine. I write backend software for a living, mostly on the JVM, with PostgreSQL underneath, Kafka in between and Kubernetes around all of it.

Each note is something I had to look up more than once. Writing it down is cheaper than searching for it a third time. The examples are simplified and the table names are made up.

How the site is made

Plain HTML and one stylesheet, served by nginx from a small virtual server. No JavaScript, no analytics, no comments. If a note is wrong, it will be quietly fixed.
