Hello, I'm sorry for not adding this topic into right subforum, but I don't know where to post mine question.
I'm really interested in learning more about processor architecture. So far I've been reading a lot about that, but without writing codes it doesn't mean anything. Recently I discovered topcoder.com and wondered if there is some similar page for processor architecture and programming?
I'm trying to find web page with quests (no need for money awards or anything like that), do you know anything about that?
