Call me vain, foolish or whatsoever, but I like it to help friends with a code snippet, a schematic or something else. It can also be a good exercise, by the way. But this is and can never be a ready solution, only some piece of help. Of course, it consumes time and efforts, but it's fun, mostly.

Sometimes, I go the opposite way and adapt the ideas of others, like the debouncing scheme using vertical counters or some state machine stuff, e.g. But again, what I adapt is only a small portion, an idea, never a ready solution.

Sometimes, it can be useful to take some ready routines from a math pack, if you code in assembler. But then you must understand them as good as if you have written them by yourself...
