it's certainly a space-filling curve problem, but it's not the traveling salesman problem. you aren't just trying to avoid revisiting nodes -- you're trying to maximize the *angle* between edges when you visit the node, to avoid overlap while you're turning the mower. which is at least an interesting wrinkle in the problem.

insightful, really?

you certainly can call someone a "fatass". there is no law against it. you can call someone anything you want, but in return someone might call you an "asshole", and they might be right.

is there a line between political correctness and politeness? or do you think we need to get rid of that too?

and fwiw, I agree, smith wasn't exactly forthcoming with the details of the case (he was switching flights, only single seat available, etc) and SW has acquitted themselves pretty well from a PR perspective. i think the man just got a little stung by a humiliating experience and wanted to rant a little.

ask someone else to review your code. explain it to them; if it's hard to explain, maybe it needs work. read other people's code voraciously and critique it (maybe privately). let your ideas about style, techniques, practices become more fluid over time, not more rigid; this is the number one cause of death among programmers. be passionate and don't feel bad if other people don't care as much.
