i love* stack overflow. i love how when you wanna know if a comparison to zero is faster than other numbers, one of the top comments will always be some shit like "This level of optimization is not worthwhile"

and fuck you man. i am doing this comparison millions of times a second because i'm writing a blitter or im writing an interpreter or im writing something else where small gains add the fuck up, maybe on underpowered embedded or otherwise old hardware, so no actually, you utter enterprise brainworm poisoned asshole, it is actually worthwhile and i resent that you're making it *my* problem that *you've* never worked on a goddamn thing in your life where performance actually fucking mattered

@eniko I think this comes from people who end up teaching a lot of amateurs online. I so often run into people who are trying to do cache aware optimizations, or avoid virtual function calls, or manually write out SSE/AVX intrinsics, when they can barely write the if statements needed to split a string, a while loop to count characters in a string, or find fizzbuzz "a really difficult challenge".

To say nothing of how often questions people ask are some sort of XY problem.
