Portland Pattern Repository
From Freepedia
The Portland Pattern Repository (PPR) is the subdirectory c2.com/ppr of the commercial Internet domain c2.com, which belongs to the company Cunningham & Cunningham (C2) from Portland, Oregon. The PPR stores computer programming design patterns, with an emphasis on extreme programming. The PPR's motto is "People, Projects & Patterns", which in the PPR's camel case is spelled "PeopleProjectsAndPatterns".
Back on September 17, 1987, programmer Howard G. Cunningham (Ward) of Tektronix co-published with Apple Computer's Kent Beck the paper Using Pattern Languages for Object-Oriented Programs about programming patterns, inspired on architect Christopher Alexander's architectural concept of "patterns", for the 1987 OOPSLA programming conference organized by the Association for Computing Machinery.
Cunningham's and Beck's idea became popular among programmers, because it helped them exchange programming ideas in a format that is easy to understand.
Cunningham & Cunningham, the programming consultancy which would later host the PPR on its Internet domain, was incorporated at the Oregon Secretary of State's Corporation Division of Salem, Oregon, on Novermber 1, 1991, and is named after Ward and his wife Karen R. Cunningham, a mathematician, school teacher and school director. Cunningham & Cunningham registered their Internet domain c2.com on October 23, 1994.
On c2.com, Ward created the Portland Pattern Repository as a means to help object-oriented programmers publish their computer programming patterns by submitting them to him. Some of those programmers attended the OOPSLA and PLoP conferences about object-oriented programming (OOP), which are well-known among object-oriented programmers, and posted their ideas on the PPR and exchanged e-mail messages with Ward.
The PPR is accompanied on c2.com by the first ever wiki (a collection of reader-modifiable Web pages), which is called WikiWikiWeb, or simply WikiWiki or Wiki (with a capital 'W'), and which is located at c2.com/cgi/wiki.
