FOSDEM was last weekend. What was your favorite presentation?

You can find talks and videos from here: https://fosdem.org/2026/schedule/

I am partial to Giacomo's talk, "You Don't Need an ORM," which reflects a rant I went on about 4 months ago. There's a lot here though, and I've only scratched the surface (and not all of the videos have been uploaded yet).

For what its worth, there are also a few presentation subjects which sound absolutely dreadful.
