Have been using pocketbase in production for a mobile app for a couple of month now and so far it was a _very_ pleasent experience. Together with the JS SDK it is now my go to backend framework for everything where I don't need specialized libraries (like ML stuff etc.)
Same here. When I was a kid in school, we all had those TI-89 calculator that one could program using Basic. When first introduced to Pi and the concept of irrational numbers, I made a script to find close matches. 355/113 was the closest I got with the slow calculator and my (most probably) very slow code.
