Portland Pattern Repository
The Portland Pattern Repository (PPR) is a repository for computer programming software design patterns. It was accompanied by a companion website, WikiWikiWeb, which was the world's first wiki. The repository has an emphasis on Extreme Programming, and it is hosted by Cunningham & Cunningham (C2) of Portland, Oregon. The PPR's motto is "People, Projects & Patterns". History On 17 September 1987, programmer Ward Cunningham, then with Tektronix, and Apple Computer's Kent Beck co-published the paper "Using Pattern Languages for Object-Oriented Programs" This paper, about software design patterns, was inspired by Christopher Alexander's architectural concept of "patterns" It was written for the 1987 OOPSLA programming conference organized by the Association for Computing Machinery. Cunningham and Beck's idea became popular among programmers because it helped them exchange programming ideas in a format that is easy to understand.

Software Design Pattern
In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. Rather, it is a description or template for how to solve a problem that can be used in many different situations. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved. Patterns that imply mutable state may be unsuited for functional programming languages. Some patterns can be rendered unnecessary in languages that have built-in support for solving the problem they are trying to solve, and object-oriented patterns are not necessarily suitable for non-object-oriented ...

Kent Beck
Kent Beck (born 1961) is an American software engineer and the creator of extreme programming, a software development methodology that eschews rigid formal specification for a collaborative and iterative design process. Beck was one of the 17 original signatories of the Agile Manifesto,"Extreme Programming", ''Computerworld'' (online), 2005, webpageComputerworld-appdev-92 the founding document for agile software development. Extreme and Agile methods are closely associated with Test-Driven Development (TDD), of which Beck is perhaps the leading proponent. Beck pioneered software design patterns, as well as the commercial application of Smalltalk. He wrote the SUnit unit testing framework for Smalltalk, which spawned the xUnit series of frameworks, notably JUnit for Java, which Beck wrote with Erich Gamma. Beck popularized CRC cards with Ward Cunningham, the inventor of the wiki. He lives in San Francisco, California and worked at social media company Facebook. In 2019, ...

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with ...

OOPSLA
OOPSLA (Object-Oriented Programming, Systems, Languages & Applications) is an annual ACM research conference. OOPSLA mainly takes place in the United States, while the sister conference of OOPSLA, ECOOP, is typically held in Europe. It is operated by the Special Interest Group for Programming Languages (SIGPLAN) group of the Association for Computing Machinery (ACM). OOPSLA is an annual conference covering topics related to object-oriented programming systems, languages and applications. Like other conferences, OOPSLA offers various tracks and many simultaneous sessions, and thus has a different meaning to different people. It is an academic conference, and draws doctoral students who present peer-reviewed papers. It also draws a number of non-academic attendees, many of whom present experience reports and conduct panels, workshops and tutorials. OOPSLA has been instrumental in helping object-oriented programming develop into a mainstream programming paradigm. It has also help ...

Christopher Alexander
Christopher Wolfgang John Alexander (4 October 1936 – 17 March 2022) was an Austrian-born British-American architect and design theorist. He was an emeritus professor at the University of California, Berkeley. His theories about the nature of human-centered design have affected fields beyond architecture, including urban design, software, and sociology. Alexander designed and personally built over 100 buildings, both as an architect and a general contractor. In software, Alexander is regarded as the father of the pattern language movement. The first wiki—the technology behind Wikipedia—led directly from Alexander's work, according to its creator, Ward Cunningham. Alexander's work has also influenced the development of agile software development. In architecture, Alexander's work is used by a number of different contemporary architectural communities of practice, including the New Urbanist movement, to help people to reclaim control over their own built environment.

WikiWikiWeb
The WikiWikiWeb is the first wiki, or user-editable website. It was launched on 25 March 1995 by programmer Ward Cunningham to accompany the Portland Pattern Repository website discussing software design patterns. The name ''WikiWikiWeb'' originally also applied to the wiki software that operated the website, written in the Perl programming language and later renamed to "WikiBase". The site is frequently referred to by its users as simply "Wiki", and a convention established among users of the early network of wiki sites that followed was that using the word with a capitalized ''W'' referred exclusively to the original site. History The software and website were developed in 1994 by Cunningham in order to make the exchange of ideas between programmers easier. The concept was based on the ideas developed in HyperCard stacks that Cunningham built in the late 1980s. On March 25, 1995, he installed the software on his company's (Cunningham & Cunningham) website, c2.com. Cunning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tektronix
Tektronix, Inc., historically widely known as Tek, is an American company best known for manufacturing test and measurement devices such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment.
