It wasn’t always so orderly. It really started as a bunch of loose directories with different things. I only actually put it under source control recently when I decided to organize it a bit better.

I had a horrible year at work. This was the first week of vacation until January. I’ve taken time to think about a new job, fix my CV, and just relax.
