This means a lot coming from you @daniel.feldroy.com, thanks!
Today I'm marvelling at @miguelgrinberg.com's Microdot framework. Concise yet understandable code. Lovely in-line documentation.
I've always respected his work, today I'm in awe of it.

I'm back from #EuroPython. I have to congratulate the organizers for including a well balanced selection of topics in the program, with a lot of options for those of us who are tired of hearing about Generative AI.
