In the last digest about Greatest software ever written, I noted a worm named Morris which is ranked 12 of greatest software by the author. Actually, after finishing my clustering searching enigne development which is based on Lucene, i am studying p2p architecture for my distributed searching engine (more precisely is webcrawler part). When I am reading some p2p loopup protocol papers such as Chord, I also noticed a guy named Morris who is one of the developers. Hmmm,? this is the same Morris, from wiki, I know that guys is now an associate professor in MIT, and was indicted because of the damage by his Morris worm. Anyway, I'd like to say that it is very interesting to know some stories about those geeks.
