@rune Thing is, I've done a lot of programmer support on IRC and such. And a *significant* chunk of the questions, probably more than half, I answered not from memory - but by having some vague inkling of what to look for, doing some quick research, and summarizing my findings.
I have yet to find a book that can answer questions faster than this process. Far as I can tell, this is pretty much the optimal process for figuring stuff out.
