Found the problem: I wasn't using router in some links and the whole app was restarted.
My vote is also for moving such Qs. Main arguments: PU already contains some Qs related to office suite and they're OnTopic there. This kind of Qs doesn't fit well to software development. So i...
I don't think this is possible in MySQL due to its computed columns limitations: Literals, deterministic built-in functions, and operators are permitted. A function is deterministic if, given th...
