a lot of us don't create code on command. especially if we aren't coding in the language of interest on a daily basis. and we reuse our old code and code we find. then we iterate and iterate until its solid and the customer is happy and then many, like me, don't have a software engineering background and don't exactly speak the same language (don't even know UML). I discovered recursion and binary search algorithms as I programmed, but if you asked me about either topic, I would not have known what you meant even though I had experience with them, until much later.
