I am a programmer by hobby and by profession. At work, I (currently) mostly work with Java and web technologies, but I enjoy playing with other languages as well. Ruby is my favorite language to use, and so I try to work with it whenever I find the opportunity (and it makes sense).
My operating system of choice is Linux (specifically Ubuntu), and my editor of choice is Emacs (I was converted by a combination of my current coworkers and articles from Steve Yegge).
