Gene Kan, peer-to-peer file-sharing programmer extraordinaire, took his own life June 29, and Wired.com has a fine tribute to the troubled but brilliant 25-year-old. Kan’s professional life revolved around developing ways for people to swap information easily and quickly. As Wired notes, Kan was among the first programmers to create an open-source version of the file-sharing application Gnutella, which lets users search for and transfer files from computer to computer. “His ability to translate complicated technology into easily understandable terms quickly led to his becoming the unofficial spokesman for Gnutella in particular, and for file-sharing applications in general,” the new site says. “Gene was one of the first people to make hay with the idea that peer-to-peer file sharing wasn’t just about music, but about a powerful approach to problems in computer networking,” adds Tim O’Reilly, of O’Reilly Publishing. “It was Gnutella and Freenet, more than Napster, that got the attention of the technical elite and made us think more deeply about the way the Internet was evolving.” Kan’s death was not entirely unexpected, Wired reports. Friends had hoped Kan was winning his hard-fought battle against depression. “We did all the things you’re supposed to do,” said Cody Oliver, Gene’s business partner in peer-to-peer search technology gonesilent.com. “We got him on Prozac; we connected him to the suicide hotlines. He promised he wouldn’t do anything drastic. But now he’s gone. It’s a really rough time.”
