Portland Pattern Repository

Portland Pattern Repository is a wiki website created by Ward Cunningham in 1995, with the goal of developing a pattern language for software design and computer programming. The website is also known as the WikiWikiWeb, and it is considered one of the first wikis on the Internet. The Portland Pattern Repository was initially hosted on a Sun Microsystems Sun-4 workstation at Cunningham's company, Cunningham & Cunningham, and it was later moved to a Linux server. The website is still active today, and it continues to be a valuable resource for software developers and computer scientists, including Donald Knuth, Edsger W. Dijkstra, and Alan Kay.

Introduction

The Portland Pattern Repository was created to facilitate the development of a pattern language for software design and computer programming, as described by Christopher Alexander in his book A Pattern Language. The website allows users to create and edit web pages using a simple markup language, and it provides a platform for software developers and computer scientists to share their knowledge and experiences, including John McCarthy, Marvin Minsky, and Seymour Papert. The Portland Pattern Repository is also a valuable resource for researchers and students, including those at Massachusetts Institute of Technology, Stanford University, and Carnegie Mellon University. The website has been used by many notable computer scientists, including Tim Berners-Lee, Vint Cerf, and Jon Postel, and it has been referenced in many publications, including Communications of the ACM, Journal of the ACM, and IEEE Computer.

History

The Portland Pattern Repository was launched in 1995 by Ward Cunningham, who is also the creator of the wiki concept. The website was initially hosted on a Sun Microsystems Sun-4 workstation at Cunningham's company, Cunningham & Cunningham, and it was later moved to a Linux server. The website was created using a custom wiki engine developed by Cunningham, and it was designed to be a platform for software developers and computer scientists to share their knowledge and experiences, including Ada Lovelace, Charles Babbage, and Alan Turing. The Portland Pattern Repository has undergone several changes over the years, including the addition of new features and the migration to new hardware and software platforms, such as Apache HTTP Server and MySQL. The website has also been referenced in many notable publications, including The New York Times, The Wall Street Journal, and Wired Magazine, and it has been used by many notable organizations, including Google, Microsoft, and IBM.

Content

The Portland Pattern Repository contains a wide range of content related to software design and computer programming, including design patterns, programming languages, and software development methodologies. The website also includes content on computer science topics, such as algorithms, data structures, and computer networks, as described by Robert Sedgewick and Kevin Wayne. The content on the website is created and edited by users, and it is available under a Creative Commons license. The website also includes links to other resources, such as books, articles, and websites, including Amazon, Google Books, and ACM Digital Library. The Portland Pattern Repository is also a valuable resource for researchers and students, including those at University of California, Berkeley, University of Washington, and Georgia Institute of Technology, and it has been referenced in many notable publications, including Science, Nature, and Proceedings of the National Academy of Sciences.

Impact

The Portland Pattern Repository has had a significant impact on the development of software design and computer programming, and it has been widely referenced in the computer science community, including by Andrew S. Tanenbaum, James Gosling, and Bjarne Stroustrup. The website has also been used by many notable organizations, including NASA, European Space Agency, and CERN, and it has been referenced in many notable publications, including The Economist, Forbes, and Fast Company. The Portland Pattern Repository has also inspired the development of other wikis and collaborative software platforms, including Wikipedia, Wikimedia Commons, and GitHub, and it has been used by many notable computer scientists, including Larry Wall, Guido van Rossum, and Yukihiro Matsumoto.

Community

The Portland Pattern Repository has a active community of users, including software developers, computer scientists, and researchers, such as Richard Stallman, Eric S. Raymond, and Linus Torvalds. The website provides a platform for users to share their knowledge and experiences, and it has been used by many notable computer scientists and software developers, including Bill Gates, Steve Jobs, and Mark Zuckerberg. The Portland Pattern Repository also has a strong connection to the open-source software community, and it has been referenced in many notable open-source software projects, including Linux, Apache HTTP Server, and MySQL. The website has also been used by many notable organizations, including Red Hat, Canonical, and SUSE, and it has been referenced in many notable publications, including Linux Journal, Open Source Magazine, and Free Software Magazine.

Technical_Aspects

The Portland Pattern Repository is built using a custom wiki engine developed by Ward Cunningham, and it is hosted on a Linux server. The website uses a simple markup language to create and edit web pages, and it provides a range of features, including version control, search, and user authentication, as described by Jeffrey Ullman and Alfred Aho. The website also uses Apache HTTP Server and MySQL to manage web traffic and database queries, and it has been optimized for performance and scalability, as described by Andrew S. Tanenbaum and David J. DeWitt. The Portland Pattern Repository has also been referenced in many notable publications, including ACM Transactions on Computer Systems, IEEE Transactions on Computers, and Journal of Systems and Software, and it has been used by many notable computer scientists, including Donald E. Knuth, Robert W. Floyd, and Edsger W. Dijkstra. Category:Software
