  My story on database schemas is published in the (Dutch) Java Magazine! Unfortunately it had to be shortened, so if you want to read the full version (or don't have access to Java Magazine), you can find it on my blog! https://jqno.nl/post/2026/02/17/old-man-yells-at-cloud-db-schema/

  EqualsVerifier 4.5 is out! It adds a new check: it fails if you use java.net.URL's equals() method, because this will make a network call that can be flaky. (Convert to java.net.URI instead.) You can suppress this with a new Warning though. Check it out: https://github.com/jqno/equalsverifier/blob/main/CHANGELOG.md #java
