I feel like that one isn’t that hard to remember because “its” stands out as a common exception to the rule for possessive singular nouns.

“It’s” is a contraction of “it is” while “its” is possessive.

Is there a link to the code? I know I could probably search for it, but if you’re going post about the code being public you could at least include a link to it.

Both of these read like the author is simultaneously looking down on both groups of developers in disgust and trying to represent them as some kind of idealized stereotype of a specific group of developers.

I think you mean here.
