Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. By providing developers the opportunity to take part in focused practice away from the pressures of 'getting things done', the coderetreat format has proven itself to be a highly effective means of skill improvement. This workshop was given to the University of Waterloo Computer Science Club.
