In May, ACM, the IEEE Computer Society, and University of California, Berkeley will pay tribute to Jim Gray, missing at sea since January 28, 2007. Gray, who won the Turing Award in 1998, is best known for his seminal contributions to database and transaction processing research, which made possible such applications as the cash machine and databases like Google's. The tribute will be held May 31 at UC Berkeley. Speakers at the tribute will include UC Berkeley's Joe Hellerstein, University of Washington's Ed Lazowska, and Microsoft's Rich Rashid and David Vaskevitch. The general session will be followed by technical sessions. For more information, visit the Jim Gray Tribute home page.
