Free and open source software, also F/OSS, FOSS, or FLOSS (free/libre/open source software) is software that is liberally licensed to grant the right of users to use, study, change, and improve its design through the availability of its source code. This approach has gained both momentum and acceptance as the potential benefits have been increasingly recognized by both individuals and corporate players.

Newcomers to the subject can be confused by the term "free". In the context of free and open source software, "free" is intended to refer to the freedom to copy and re-use the software, rather than to the price of the software. The Free Software Foundation, an organization that advocates for free software, suggests that to understand the concept, one should "think of free as in free speech, not as in free beer".

Free and open source software is an inclusive term which covers both free software and open source software which, despite describing similar development models, have differing cultures and philosophies. Free software focuses on the philosophical freedoms it gives to users while open source focuses on the perceived strengths of its peer-to-peer development model. FOSS is a term that can be used without particular bias towards either political approach.

Free software licences and open source licenses are used by many software packages. The licenses have important differences, which mirror the differences in the ways the two kinds of software can be used and distributed and reflect differences in the philosophy behind the two.

By mid 2007, enough companies were opening some source while keeping other advanced functionality closed, that the common meaning of "open source" came to include what is now called commercial open source software (COSS) as well. Today either the specific terms free software/FOSS/FLOSS or COSS are often used instead of the more general term "open source" in order to differentiate between the two different models and preserve the original meaning of the free software/FOSS/FLOSS space.

History

Main article: History of free and open source software

In the 1950s, 1960s, and 1970s, it was normal for computer users to have the freedoms that are provided by free software. Software was commonly shared by individuals who used computers and by hardware manufacturers who were glad that people were making software that made their hardware useful. Organizations of users and suppliers were formed to facilitate the exchange of software, see, for example, SHARE. By the late 1960s change was inevitable: software costs were dramatically increasing, a growing software industry was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software, and some customers able to better meet their own needs did not want the costs of "free" software bundled with hardware product costs. In United States vs. IBM, filed January 17, 1969, the government charged that bundled software was anticompetitive. While some software might always be free, there would be a growing amount of software that was for sale only. In the 1970s and early 1980s, the software industry began using technical measures (such as only distributing binary copies of computer programs) to prevent computer users from being able to study and modify software. In 1980 copyright law was extended to computer programs.

In 1983, Richard Stallman, longtime member of the hacker community at the MIT Artificial Intelligence Laboratory, announced the GNU project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users. Software development for the GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. An article outlining the project and its goals was published in March 1985 titled the GNU Manifesto. The manifesto also focused heavily on the philosophy of free software. He developed The Free Software Definition and the concept of "copyleft", designed to ensure software freedom for all.

The Linux kernel, started by Linus Torvalds, was released as freely modifiable source code in 1991. The licence wasn't exactly a free software licence, but with version 0.12 in February 1992, he relicensed the project under the GNU General Public License. Much like Unix, Torvalds' kernel attracted the attention of volunteer programmers.

In 1997, Eric Raymond published The Cathedral and the Bazaar, a reflective analysis of the hacker community and free software principles. The paper received significant attention in early 1998 and was one factor in motivating Netscape Communications Corporation to release their popular Netscape Communicator Internet suite as free software. This code is today better known as Mozilla Firefox and Thunderbird.

Netscape's act prompted Raymond and others to look into how to bring free software principles and benefits to the commercial software industry. They concluded that FSF's social activism was not appealing to companies like Netscape, and looked for a way to rebrand the free software movement to emphasize the business potential of the sharing of source code. The new name they chose was "open source," and quickly Bruce Perens, publisher Tim O'Reilly, Linus Torvalds, and others signed on to the rebranding. The Open Source Initiative was founded in February 1998 to encourage use of the new term and evangelize open source principles.

Naming

Free software

The Free Software Definition, written by Richard Stallman and published by Free Software Foundation (FSF), defines free software as a matter of liberty, not price. The earliest known publication of the definition was in the February 1986 edition of the now-discontinued GNU's Bulletin publication of FSF. The canonical source for the document is in the philosophy section of the GNU Project website. As of April 2008, it is published there in 39 languages.

Open source

The Open Source Definition is used by the Open Source Initiative to determine whether a software license can be considered open source. The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens. Perens did not base his writing on the "four freedoms" of Free Software from the Free Software Foundation, which were only widely available later.

FOSS

The first known use of the phrase "free open source software" on Usenet was in a posting on 18 March, 1998, just a month after the term "open source" itself was coined. In February 2002, "F/OSS" appeared on a Usenet newsgroup dedicated to Amiga computer games. In early 2002, MITRE used the term "FOSS" in what would later be their 2003 report Use of Free and Open Source Software (FOSS) in the U.S. Department of Defense.

FLOSS

"FLOSS" was used in 2001 as a project acronym by Rishab Aiyer Ghosh as an acronym for free/libre/open source software. Later that year, the European Commission (EC) used the phrase when they funded a study on the topic.

Unlike "libre software", which aimed to solve the ambiguity problem, "FLOSS" aimed to avoid taking sides in the debate over whether it was better to say "free software" or to say "open source software".

Proponents of the term point out that parts of the FLOSS acronym can be translated into other languages, with for example the "F" representing free (English) or frei (German), and the "L" representing libre (Spanish or French), livre (Portuguese), or libero (Italian), and so on. However, this term is not often used in official, non-English, documents, since the words in these languages for "free as in freedom" do not have the ambiguity problem of English's "free".

By the end of 2004, the FLOSS acronym had been used in official English documents issued by South Africa, Spain, and Brazil.

Controversy

Founder of the GNU Project, Richard Stallman, was accused of sexism in a July 4th, 2009 keynote address; and a comment by computer programmer Eric Raymond brought to attention the amount of female participation with open source software.

Hackerdom is still predominantly male. However, the percentage of women is clearly higher than the low-single-digit range typical for technical professions, and female hackers are generally respected and dealt with as equals. . . . When asked, hackers often ascribe their culture's gender- and color-blindness to a positive effect of text-only network channels, and this is doubtless a powerful influence. Also, the ties many hackers have to AI research and SF literature may have helped them to develop an idea of personhood that is inclusive rather than exclusive --- after all, if one's imagination readily grants full human rights to future AI programs, robots, dolphins, and extraterrestrial aliens, mere color and gender can't seem very important any more.

— Eric Raymond

Adoption

  • In 2005 the Government of Peru voted to adopt open source across all its bodies. The 2002 response to Microsoft's critique is available online. In the preamble to the bill, the Peruvian government stressed that the choice was made to ensure that key pillars of democracy were safeguarded: "The basic principles which inspire the Bill are linked to the basic guarantees of a state of law."
  • In December 2004, law in Venezuela (Decree 3390) went into effect, mandating a two year transition to open source in all public agencies. As of June 2009 this ambitious transition is still under way.
  • Vietnam - the Ministry of Information and Communications has issued an instruction on using open source software at state agencies.
