Mate, nothing against you but this question comes over and over, times and times again. I won't even bother searching for the links to post here because if you didn't do it, why should I?
Specially from a post coming from an apparent throwaway account that does nothing more that ask questions. Sorry but this one was for you.
You don't mention even a slight hint about how it all works, or if one of those ideas was turned into a business. Also, 10$ seems low for a (possible?) life-changing course. If I could find ideas that easily my life might be different.
I've been wanting to learn clojure for a while but for someone in webdev who never coded in a functional style, I never could grasp it. Do you have any good resource to start with clojure?
