Back in around 2006 I was doing GPGPU regex and string matching and decided to google around for parallel string matching algorithms. I spent a good chunk of time scrolling around in the Vishkin's algorithm implementation and wondering why it all felt so familiar; it was only when I scrolled back to the top of the file that I realized it was familiar because I wrote it. A fine example of why you should comment your code, as the person who reads it in 10 years from now will be a stranger, even if that person is you.
