For anyone that has not heard it already, FOSDEM 2021 is up right now.
I'm eagerly awaiting for Ricardo Wurmus' talk on Guix workflow language, and I'll be around many other talks either. Tomorrow the Declarative and minimalistic computing track has many interesting talks on Guix, Spritely, Nyxt and many other very interesting projects.
As always, it's a very nice work, and very accesible through the matrix protocol. Check around and you'll surely find some very interesting talks on a wide array of subjects in free software.
