Haha also yearly for me. I have actually written a small utility in rust that interacts with mysql, but it was basically just transposing python to rust, plus it’s hacky as hell and I didn’t really learn anything.
I’ve stuck that rust book in the “one day” silo, along with the guitar, learning French, eating healthy, and getting enough sleep. One day.
There’s actually a Python-based framework that can make mobile apps called Kivy, but as you might expect it would not be terribly performant.
