So the first thing that Y.T.'s mother does, having read the new subchapter on bathroom tissue pools, is to sign on to a subsystem of the main computer system that handles the particular programming project she's working on. She doesn't know what the project is—that's classified—or what it's called. It's just her project. She shares it with a few hundred other programmers, she's not sure exactly who. And every day when she signs on to it, there's a stack of memos waiting for her, containing new regulations and changes to the rules that they all have to follow when writing code for the project. These regulations make the business with the bathroom tissue seem as simple and elegant as the Ten Commandments.
