Improve Readability With Positive Booleans

- Max Kanat-Alexander tl;dr: (1) Name your flags and variables in such a way that they represent the positive check you wish to make - the presence of something, something being enabled, something being true - rather than the negative check you wish to make - the absence of something, something being disabled, something being false. (2) If your conditional looks like “if not … else …” then reverse it to put the positive case first.
