Quite often I go through pain to discover how to do something useful, in this case how to get PHP running on Google App Engine without the 'resin.jar too big' problem, but I have nowhere to let people know. In this particular case, the web answers were incomplete, outdated or plain wrong.
I could create a blog, but it's overkill. I just want let programmers know a quick solution/approach. I'm not sure it's the done thing to ask a question and then answer it.
In short, it'd be nice to be able to just dump a sort of combined question/answer/snippet, then let others comment as usual, shoot it down, like it, whatever.
How do the rest of you approach this?
