Trying to let my 3yo try as many different technology interfaces as possible. Mouse: not too bad, especially after reducing sensitivity. Keyboard: WASD is easy to lose track of in a sea of buttons. Controller: requires both hands together, which is tricky. Arguably the left hand is more important too, hard for a right hander.

I'm implementing an interpreter, and wondering how often I should check for interruptions (e.g. Ctrl-C). I don't want to spend too much CPU time checking whether I've been interrupted, but I also want slow programs to stop promptly. It's tricky.

I'm adding a += operator to my programming language, because writing `x = x + 1` is tedious. This opens the tricky design question of which operators should support this. Is += and -= sufficient, or do you expect things like >>= and **= to be available?
