Last month, I mentioned that I've been taking a class in Ruby on Rails, a programming framework that powers tens of thousands of websites worldwide. Why go back to school? A couple of reasons. First, I want to be a better co-worker. I'm a designer, but I rely on programmers to bring my ideas to life. By learning to code myself, I think I can make things easier for all of us. Similarly, I want to be able to build things on my own, without having to bother a programmer.
