the operating system allows you to write software badly unlike Mac or Linux
Linux has a lot of good features but I don't know that that it would prevent you from writing bad code...
I had assumed that with all the talk of new technology
Next time try reading up on it instead. Some people assumed with all the talk of new technology that by the year 2000 we'd all be driving flying cars and we'd have colonies on the moon...
Most normal cells do not divide frequently, therefore their chromosomes are not at risk of shortening and they do not require high telomerase activity. In contrast, cancer cells have the ability to divide infinitely and yet preserve their telomeres. How do they escape cellular senescence? One explanation became apparent with the finding that cancer cells often have increased telomerase activity. It was therefore proposed that cancer might be treated by eradicating telomerase. Several studies are underway in this area, including clinical trials evaluating vaccines directed against cells with elevated telomerase activity.
you go for the cheapest source first
I would rather say you go for the most cost effective improvements first. I assume you mean to go after the low hanging fruit first. There's no point wasting time on optimizations that don't give decent returns for your dollar. Even if they're cheap they're still a waste of money. It may well be possible to spend less on one expensive but effective optimization rather than implementing a bunch of cheap but ineffective optimizations - even if they both yield the same net improvement.
The top end of your scale is about right, 40C is 104F, which I do believe as you, is too damn hot, however, I'd put the -10C into the biting cold category, and -20 is simply too cold to go outside. 0 to -9 is the normal winter day and anything slightly above freezing is mild winter.
That depends entirely on where you live, my friend. Here in Norway, some schoolchildren will happily walk to school in -20C on a daily basis during the winter, where I currently live -10C is pretty cold but yet quite normal and certainly doesn't inhibit daily life. And don't even get me started on these wimpy "snow days" that seem to play such a large part of American children's hopes of getting off school.

Not sure about Mac/Linux. The more expensive professional ones support them (as well as things like logging and two-factor security), but you can get them for as little as £10 if you just need a basic one.
Friction is a drag.
