452: Numbers on Computers Are Weird

Julia Evans spoke with us about how computers compute. We discussed number representation including floating point as well as Julia's extensive collection of 'zines and comics.

Julia's zines about debugging, managers, Linux commands, and more are available on WizardZines.com. If you want samples, check out the comics section. Also, the experiments (aka playgrounds) are great additions to the zines (and fun on their own), letting you explore without changing your own DNS or removing all the files from your root directory. If you want to check out numbers, look at memory-spy (or from other sites like https://float.exposed/ and https://integer.exposed/)

Julia also has a detailed blog on jvns.ca and active github repositories
