while this one works, the one Martin posted is a better solution. They're both O(n) in terms of time, but Martin's is O(1) wrt space, whereas this one is Also O(n) -- it reads in and stores the entire file and then picks out a line. Unfortunately, it doesn't lend itself as well to extension to the case of "shuffling a file". But for one random line from a file, it's a very elegant solution.
