> 1. How much commentary should I write? I try to write not too many notes because I write code, and some say code should be self-documenting. So it's the same old question of how many comments should there be along the code.

I think the best I've heard this was by a friend who said something akin to this;

Programming is the art of solving problems by codifying complexity. Generally, the self documenting part is the 'defining the problem' portion of the code. But in every problem, there's a certain amount of irreducible complexity, or it wouldn't be a problem.

There's going to be some part of the code where you wish you could make it simpler, or you wish you understood it better, or you wish you could break it down into smaller components but there's no 'good way' to do it in the system you're working in. Or, the way you have working is 'good enough' and it's not worth the investment from some (business needs angle) in making it any better.

This is the portion of the code you should comment, and document, and do so liberally and in detail.
