If the Comments Are Ugly, the Code Is Ugly
itwbennett writes "What do your comments say about your code? Do grammatical errors in comments point to even bigger errors in code? That's what Esther Schindler contends in a recent blog post. 'Programming, whether you're doing it as an open source enthusiast or because you're workin' for The Man, is an exercise in attention to detail,' says Schindler. 'Someone who writes software must be a nit-picker, or the code won't work ... Long-winded 'explanations' of the code in the application's comments (that is, the ones that read like excuses) indicate that the developer probably didn't understand what he was doing.'"
All my variables are single digits too. I try to keep method names no longer than 4 digits and I get a wood over cryptic package names. When you write perfect code you don't need comments or dumbed down names. It's just so obvious what is happening in the code.
