I’ve completed almost all my degree requirements at SJSU and have started my two semester thesis. I’m still trying to narrow my thesis scope, but early on I picked out a good thesis advisor. This professor is in high demand among the graduate students, and no wonder: He’s extremely bright, an excellent instructor, and a prolific developer himself. He’s also extremely busy, and could take only two more graduate students. Over the Christmas break he held a coding competition with the two top submissions getting the spots.
The challenge was the following: Given a URL, implement (in PHP) a hashing function that produces a fixed length, approximately unique key that can still identify some of the “tokens” that created it.
