I don’t know why I find this so fascinating, but I do. This page shows the results of running grep (a Unix search function) on the Windows 2000 source code. It’s like peeking inside the sausage factory: you get to see the workers chopping meat, spitting, swearing, mixing bugs into the meal, and not cleaning up after themselves. Nevermind security risks: This hints at a gigantic, sloppy, sprawling mess of code filled with debris and cruft. To be fair, every mature operating system’s code probably looks this way. But it’s fascinating to get a glimpse.
