Open source describes practices in production and development that promote access to the end product's sources. Some consider it as a philosophy, and others consider it as a pragmatic methodology. Before open source became widely adopted, developers and producers used a variety of phrases to describe the concept; the term open source gained popularity with the rise of the Internet and its enabling of diverse production models, communication paths, and interactive communities.The complexity of such communication relates to Brooks' law, and it is also described by Eric S. Raymond, "Brooks predicts that as your number of programmers N rises, work performed scales as N but complexity and vulnerability to bugs rises as N-squared. N-squared tracks the number of communications paths (and potential code interfaces) between developers' code bases." -- "The Revenge of the Hackers". 2000. Subsequently, open source software became the most prominent face of open source.
The open source model can allow for the concurrent use of different agendas and approaches in production, in contrast with more centralized models of development such as those typically used in commercial software companies.Raymond, Eric S. The Cathedral and the Bazaar. ed 3.0. 2000.
History
Those involved with journalism and open source intelligence used the earliest known practices of open source that focused on accessibility rather than modification of sources. Software developers used to commonly release their code under public domain until they wanted to control how such freely accessible sources are modified and distributed. Developers, like the Free Software Foundation, began to license their work, but they still kept it as free software. More on [ Open source ]
