At my current job, we've switched from Star Wars characters to colors. While I can understand that having a testing machine called "jarjar" is a bit, well, jarring to those with less geeky proclivities. But mentally associating colors to certain servers is a bit too bland. Maybe that's just the way my brain works…

(Worst sin I've commited, name-wise: Naming my desktop PC dunsinane and my laptop birnham)
