Class was, well, class. I had a delightful time learning, and Sandstrom went into the finer details of how things work. I was evidently right to have been suspicious when a certain former friend and gray hat hacker suggested assigning a certain nonroutable address to poor old Enki, as there are Things [unspecified] that Can Be Done with that information. Just like I'm not always happy about giving out my current OS details, which I was perfectly justified about feeling.
So that was that. I returned The Hobbit to the library, and got out Narcissus in Chains. Then I came home and Things Were Good.
Am now embarking upon that whole thing where I clean/do laundry/etc. redshoeson and I will be hanging out later.
