I'm a bit unsure about how SO works in regards to questions about learning/guides to using/whatever. For example, I'd really like to learn about mmap in Python, but I'm not really sure how to get started.
I don't think a question like:
Where could I learn more about Python mmap? I'm trying to handle a memory usage problem with a Python package I've been using and I think mmap could be the answer.
really fits the Q&A model for Stack Overflow. Yet the FAQ also seems to permit this sometimes (e.g. the FAQ says I would like someone to explain __ to me will probably be a valid question. If I were to ask it, I'd provide more details, but I wouldn't be able to say "well, I've already tried XYZ", because I'm just starting to dig into the problem.
So, would this be an okay question for Stack Overflow? Is there another Stack Exchange site where I could ask this question? (and then, I guess, come back to Stack Overflow when I have questions about trying to figure it out).
EDIT: I looked at the Programmers Stack Exchange site, but I'm not clear where this question fits between Programmers and SO.
