> where did you get that coding sample you mentioned I learned programming by reading books and trying samples from there, then, step by step, beginning to understand how parts play together and why some things are faster than another. I could _feel_ loops and recursion, tinker with them, before trying to understand them theoretically. I can't do that in learning math (yet; Wolfram Alpha is changing it). It's either I understand the exact meaning of symbols, or I don't. There are no intermediary steps. And being rigorous is not the same with being consistent. (There isn't much consistency in programming, either, but this is a minor problem).
