ESR wrote instructions on how to ask questions the smart way.

http://www.catb.org/~esr/faqs/smart-questions.html

Basically, do your homework--show you've put in some effort to answer your
own question. Nobody was born knowing everything; the people you're asking
to help you got help from someone in their past.
Most folks remember this and repay their debts by helping others. These are
the people you're looking for.

As for the assholes? People *do* have a right to be assholes if that's what
they want. Don't worry about them. Take what you need and leave the rest.
Keep coming back and more will be revealed to you when you are ready.
