Noneuclidian Doom

Found by cortex over on Metafilter was this 2022 talk where someone noticed that the value of the constant pi in the source code of Doom was slightly incorrect. It’s a very tiny difference, and the results aren’t really visible in the game. So Luke Gotszling got the idea to compile the game with different values, and to see what the results are. They gave a talk about it! It’s 19 minutes long, and may be interesting if you’re of that frame of mind.

Computing Pi on a NES

Today’s link is to a madperson who explains how to compute digits of pi on a NES’s 6502 to an arbitrary length. As you do. Along the way it explains how to multiply and divide in binary on a processor without hardware support. It’s around nine minutes long, but if you want a machine to get to the end of pi it’ll probably take a tad bit longer.

We link to such a variety of things here. Sometimes we post light videos where someone has Kirby do funny things. Sometimes we show explainers that explain how to do arithmetic on old processors. I presume that you’ll take from these what you want, and leave the rest to the crazy people, by definition the people who are not you. I understand.
