Hey there \o. original author of said hubba article :)

Just wanted to offer some missing bits you might find interesting, specifically, the third function you don't recognise is the random function from the original Tetris on the NES. It comes from the article[0] that went through all the asm of the NES Tetris cartridge.

And yup, that first one is quite quite terrible for random - it came from some of the first results in StackOverflow intentionally looking for something that was overly simple and "bad" at random.

But really the article was about testing and visualising how your own random functions might be.
