In production and development, open source is a philosophy,^{[not in citation given][not in citation given]} or pragmatic methodology^{[not in citation given]} that promotes free redistribution and access to an end product's design and implementation details. Before the phrase open source became widely adopted, developers and producers used a variety of phrases to describe the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code.^{[citation needed]} Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities. The open-source software movement was born to describe the environment that the new copyright, licensing, domain, and consumer issues created.^{[citation needed]}

The open-source model includes the concept of concurrent yet different agendas and differing approaches in production, in contrast with more centralized models of development such as those typically used in commercial software companies. A main principle and practice of open-source software development is peer production by bartering and collaboration, with the end-product, source-material, "blueprints", and documentation available at no cost to the public. This is increasingly being applied in other fields of endeavor, such as biotechnology.

Jeremy Allison is a computer programmer known for his contributions to the free software community, notably to Samba, a re-implementation of SMB/CIFS networking protocol, released under the GNU General Public License.

Other contributions include the early versions of the pwdump password cracking utility.

During his career, Jeremy Allison has consistently defended the free software approach:

This commitment to free software culminated with his decision to leave Novell in protest of a patent deal that was considered by many as a FUD attack on Linux and other free software, and by Allison as breaking section 7 of the GNU General Public License.

Clay Shirky (born 1964) is an American writer, consultant and teacher on the social and economic effects of Internet technologies. He has a joint appointment at New York University (NYU) as a Distinguished Writer in Residence at the Arthur L. Carter Journalism Institute and Assistant Arts Professor in the New Media focused graduate Interactive Telecommunications Program (ITP). His courses address, among other things, the interrelated effects of the topology of social networks and technological networks, how our networks shape culture and vice-versa.

He has written and been interviewed extensively about the Internet since 1996. His columns and writings have appeared in Business 2.0, the New York Times, the Wall Street Journal, the Harvard Business Review and Wired.

Shirky divides his time between consulting, teaching, and writing on the social and economic effects of Internet technologies. His consulting practice is focused on the rise of decentralized technologies such as peer-to-peer, web services, and wireless networks that provide alternatives to the wired client–server infrastructure that characterizes the World Wide Web. He is a member of the Wikimedia Foundation's Advisory Board.

Elon Musk (born June 28, 1971) is a South African-born American business magnate, engineer and inventor. He is best known for co-founding SpaceX, Tesla Motors and X.com, which later became Paypal after acquiring the service. He is currently the CEO and Chief Designer of SpaceX, CEO and Product Architect of Tesla Motors and Chairman of SolarCity. While at those companies, Musk co-designed the first viable electric car of the modern era, the Tesla Roadster, a private successor to the Space Shuttle, Falcon 9/Dragon, and the world's largest Internet payment system, PayPal.

Elon Musk was born in Pretoria, South Africa, the son of a Canadian-American mother and a South African father. His maternal grandfather was from Minnesota, and had moved to Saskatchewan, where Musk's mother was born. His father is an engineer and his mother is an author, nutritionist and model, appearing on the cover of New York Magazine in 2011 and a Time Magazine supplement in 2010.

Musk bought his first computer at age 10 and taught himself how to program; by the age of 12 he sold his first commercial software for about $500, a space game called Blastar.
