"Having expertise is one thing; conveying it to others is quite another. Patterns do just that." Patterns are a literary form with roots in literate programming, in a design movement of the same name in contemporary architecture, and in the practices common to the ageless literature of any culture. This volume, with contributions from the biggest names in the patterns community, is the second in a series documenting patterns for professional software developers. These patterns capture solutions to a plethora of recurring problems in software design and development, including language-specific patterns and idioms; general- and special-purpose patterns; architectural patterns; process and organizational patterns; expositional patterns; and patterns for concurrent programming, distributed systems, and reactive systems. This new collection not only reveals secrets of great software professionals but also makes those secrets easy to apply to your own work. 0201895277B04062001
