A large group of us in the IR lab recently finished a class in Advanced Algorithms. Here's an algorithms tribute, Find The Longest Path [lyrics] to the tune of Billy Joel's The Longest Time. It was reportedly written in 1988 by a grad student at John's Hopkins during a particularly hard algorithms final.
Now that the semester is over, it's good to be able to focus on research again. After all, the SIGIR 2009 deadline is only about a month away!
