Gates and Allen joined with Ric Weiland and Gates' childhood best friend and first collaborator, Kent Evans, to form the Lakeside Programming Club and find bugs in Computer Center Corporation's software, in exchange for extra computer time. In 1972, after Evans' sudden death due to a mountain climbing accident, Gates turned to Allen for help finishing an automated system of Lakeside's entire class scheduling procedure. They then formed Traf-O-Data to make traffic counters based on the Intel 8008 processor. According to Allen, he and Gates would go "dumpster diving" in their teenage years for computer program code.
