Stereotypes portray software engineers as a reckless lot, and stereotypes paint software configuration management (SCM) devotees as inflexible. Based on these impressions, it is no wonder that projects can be riddled with tension! The truth probably lies somewhere in between these stereotypes, and this book shows how proven SCM practices can foster a healthy team-oriented culture that produces better software. The authors show that workflow, when properly managed, can avert delays, morale problems, and cost overruns. A patterns approach (proven solutions to recurring problems) is outlined so that SCM can be easily applied and successfully leveraged in small to medium sized organizations. The patterns are presented with an emphasis on practicality. The results speak for themselves: improved processes and a motivated workforce that synergize to produce better quality software.

Play is one of humanity's straightforward yet deceitful ideas: though the notion is unanimously agreed upon to be universal, used for man and animal alike, nothing defines what all its manifestations share, from childish playtime to on stage drama, from sporting events to market speculation. Within the author's anthropological field of work (Mongolia and Siberia), playing holds a core position: national holidays are called "Games," echoing in that way the circus games in Ancient Rome and today's Olympics. These games convey ethical values and local identity. Roberte Hamayon bases her analysis of the playing spectrum on their scrutiny. Starting from fighting and dancing, encompassing learning, interaction, emotion and strategy, this study heads towards luck and belief as well as the ambiguity of the relation to fiction and reality. It closes by indicating two features of play: its margin and its metaphorical structure. Ultimately revealing its consistency and coherence, the author displays play as a modality of action of its own. "Playing is no 'doing' in the ordinary sense" once wrote Johan Huizinga. Isn't playing doing something else, elswhere and otherwise ?
