67-535: Utah GLX was a project aimed at creating a fully free and open-source basic hardware-accelerated 3D renderer using the OpenGL rendering API on Linux kernel -based operating systems. Utah GLX predates Direct Rendering Infrastructure , which is what is used as of 2014. John Carmack worked on Utah GLX. This Unix -related article is a stub . You can help Misplaced Pages by expanding it . Free and open-source Free and open-source software ( FOSS )
134-455: A linker . The GNU system required its own C compiler and tools to be free software, so these also had to be developed. By June 1987, the project had accumulated and developed free software for an assembler , an almost finished portable optimizing C compiler ( GCC ), an editor ( GNU Emacs ), and various Unix utilities (such as ls , grep , awk , make and ld ). They had an initial kernel that needed more updates. Once
201-455: A Linux distribution) qualifies as free (libre), and helps distribution developers make their distributions qualify. The list mostly describes distributions that are a combination of GNU packages with a Linux-libre kernel (a modified Linux kernel that removes binary blobs, obfuscated code, and portions of code under proprietary licenses) and consist only of free software (eschewing proprietary software entirely). Distributions that have adopted
268-478: A fully free (libre) GNU/Linux distribution. From the mid-1990s onward, with many companies investing in free software development, the Free Software Foundation redirected its funds toward the legal and political support of free software development. Software development from that point on focused on maintaining existing projects, and starting new projects only when there was an acute threat to
335-606: A niche role outside of the mainstream of private software development. However the success of FOSS Operating Systems such as Linux, BSD and the companies based on FOSS such as Red Hat , has changed the software industry's attitude and there has been a dramatic shift in the corporate philosophy concerning its development. Users of FOSS benefit from the Four Essential Freedoms to make unrestricted use of, and to study, copy, modify, and redistribute such software with or without modification. If they would like to change
402-646: A proprietary operating system. According to its manifesto, the founding goal of the project was to build a free operating system, and if possible, "everything useful that normally comes with a Unix system so that one could get along without any software that is not free." Development was initiated in January 1984. In 1991, the Linux kernel appeared, developed outside the GNU project by Linus Torvalds , and in December 1992 it
469-466: A result, any user who obtains the software legally has the same freedoms as the rest of its users do. The GNU Project and the Free Software Foundation sometimes differentiate between "strong" and "weak" copyleft. "Weak" copyleft programs typically allow distributors to link them together with non-free programs, while "strong" copyleft strictly forbids this practice. Most of the GNU Project's output
536-581: A single unified term that could refer to both concepts, although Richard Stallman argues that it fails to be neutral unlike the similar term; "Free/Libre and Open Source Software" (FLOSS). Richard Stallman 's Free Software Definition , adopted by the FSF, defines free software as a matter of liberty, not price, and that which upholds the Four Essential Freedoms. The earliest known publication of this definition of his free software definition
603-441: A variety of FOSS projects, including both free software and open-source. GNU Project The GNU Project ( / ɡ n uː / ) is a free software , mass collaboration project announced by Richard Stallman on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and computing devices by collaboratively developing and publishing software that gives everyone
670-469: A version of GNU/Hurd that is suitable for production environments since the commencement of the GNU/Hurd project over 33 years ago. A stable version (or variant) of GNU can be run by combining the GNU packages with the Linux kernel , making a functional Unix-like system. The GNU project calls this GNU/Linux, and the defining features are the combination of: Within the GNU website, a list of projects
737-487: Is laid out and each project has specifics for what type of developer is able to perform the task needed for a certain piece of the GNU project. The skill level ranges from project to project but anyone with background knowledge in programming is encouraged to support the project. The packaging of GNU tools, together with the Linux kernel and other programs, is usually called a Linux distribution (distro). The GNU Project calls

#1732791904485804-550: Is now independently managed by the GNOME Project . GNU Enterprise ( GNUe ) was a meta-project started in 1996, and can be regarded as a sub-project of the GNU Project. GNUe's goal is to create free "enterprise-class data-aware applications" ( enterprise resource planners , etc.). GNUe is designed to collect Enterprise software for the GNU system in a single location (much like the GNOME project collects Desktop software),it
871-490: Is released under a strong copyleft, although some is released under a weak copyleft or a lax, push-over free software license. The first goal of the GNU project was to create a whole free-software operating system. Because UNIX was already widespread and ran on more powerful machines, compared to contemporary CP/M or MS-DOS machines of time, it was decided it would be a Unix-like operating system. Richard Stallman later commented that he considered MS-DOS "a toy". By 1992,
938-407: Is software that is available under a license that grants the right to use, modify, and distribute the software, modified or not, to everyone free of charge. The public availability of the source code is, therefore, a necessary but not sufficient condition. FOSS is an inclusive umbrella term for free software and open-source software . FOSS is in contrast to proprietary software , where the software
1005-562: Is the same detailed history as at their web site. The GNU Manifesto was written by Richard Stallman to gain support and participation in the GNU Project. In the GNU Manifesto, Stallman listed four freedoms essential to software users: freedom to run a program for any purpose, freedom to study the mechanics of the program and modify it, freedom to redistribute copies, and freedom to improve and change modified versions for public use. To implement these freedoms, users needed full access to
1072-534: Is today better known as Mozilla Firefox and Thunderbird . Netscape's act prompted Raymond and others to look into how to bring the FSF's Free software ideas and perceived 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 sharing and collaborating on software source code. The new name they chose
1139-748: Is under restrictive copyright or licensing and the source code is hidden from the users. FOSS maintains the software user's civil liberty rights via the " Four Essential Freedoms " of free software. Other benefits of using FOSS include decreased software costs, increased security against malware , stability, privacy , opportunities for educational usage, and giving users more control over their own hardware. Free and open-source operating systems such as Linux distributions and descendants of BSD are widely used today, powering millions of servers , desktops , smartphones , and other devices. Free-software licenses and open-source licenses are used by many software packages today. The free software movement and
1206-587: Is used by the Open Source Initiative (OSI) to determine whether a software license qualifies for the organization's insignia for open-source software . 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 Essential Freedoms of free software from the Free Software Foundation , which were only later available on
1273-738: The United Space Alliance , which manages the computer systems for the International Space Station (ISS), regarding why they chose to switch from Windows to Linux on the ISS. In 2017, the European Commission stated that "EU institutions should become open source software users themselves, even more than they already are" and listed open source software as one of the nine key drivers of innovation, together with big data , mobility, cloud computing and
1340-556: The free software community . One of the most notable projects of the GNU Project is the GNU Compiler Collection , whose components have been adopted as the standard compiler system on many Unix-like systems. The copyright of most works by the GNU Project is owned by the Free Software Foundation. The GNOME desktop effort was launched by the GNU Project because another desktop system, KDE ,
1407-610: 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

#17327919044851474-494: The internet of things . In 2020, the European Commission adopted its Open Source Strategy 2020-2023 , including encouraging sharing and reuse of software and publishing Commission's source code as key objectives. Among concrete actions there is also to set up an Open Source Programme Office in 2020 and in 2022 it launched its own FOSS repository https://code.europa.eu/ . In 2021, the Commission Decision on
1541-458: The kernel and the compiler were finished, GNU was able to be used for program development . The main goal was to create many other applications to be like the Unix system. GNU was able to run Unix programs but was not identical to it. GNU incorporated longer file names, file version numbers, and a crash-proof file system. The GNU Manifesto was written to gain support and participation from others for
1608-609: The open-source software movement are online social movements behind widespread production, adoption and promotion of FOSS, with the former preferring to use the terms FLOSS , free or libre. "Free and open-source software" (FOSS) is an umbrella term for software that is simultaneously considered both free software and open-source software . The precise definition of the terms "free software" and "open-source software" applies them to any software distributed under terms that allow users to use, modify, and redistribute said software in any manner they see fit, without requiring that they pay
1675-494: The source code . To ensure code remained free and provide it to the public, Stallman created the GNU General Public License (GPL), which allowed software and the future generations of code derived from it to remain free for public use. Although most of the GNU Project's output is technical in nature, it was launched as a social, ethical, and political initiative. As well as producing software and licenses,
1742-638: The EU. These recommendations are to be taken into account later in the same year in Commission's proposal of the "Interoperable Europe Act" . While copyright is the primary legal mechanism that FOSS authors use to ensure license compliance for their software, other mechanisms such as legislation, patents, and trademarks have implications as well. In response to legal issues with patents and the Digital Millennium Copyright Act (DMCA),
1809-655: The FOSS ecosystem, several projects decided against upgrading to GPLv3. For instance the Linux kernel , the BusyBox project, AdvFS , Blender , and the VLC media player decided against adopting the GPLv3. Apple , a user of GCC and a heavy user of both DRM and patents, switched the compiler in its Xcode IDE from GCC to Clang , which is another FOSS compiler but is under a permissive license . LWN speculated that Apple
1876-527: The Free Software Foundation released version 3 of its GNU General Public License (GNU GPLv3) in 2007 that explicitly addressed the DMCA and patent rights. After the development of the GNU GPLv3 in 2007, the FSF (as the copyright holder of many pieces of the GNU system) updated many of the GNU programs' licenses from GPLv2 to GPLv3. On the other hand, the adoption of the new GPL version was heavily discussed in
1943-510: The GNU FSDG include Dragora GNU/Linux-Libre , GNU Guix System , Hyperbola GNU/Linux-libre , Parabola GNU/Linux-libre , Trisquel GNU/Linux , PureOS , and a few others. The Fedora Project's distribution license guidelines were used as a basis for the FSDG. The Fedora Project's own guidelines, however, currently do not follow the FSDG, and thus the GNU Project does not consider Fedora to be
2010-423: The GNU Project has published a number of writings, the majority of which were authored by Richard Stallman. The GNU project uses software that is free for users to copy, edit, and distribute. It is free in the sense that users can change the software to fit individual needs. The way programmers obtain the free software depends on where they get it. The software could be provided to the programmer from friends or over
2077-475: The GNU Project in a Usenet message in September 1983. Despite never having used Unix prior, Stallman felt that it was the most appropriate system design to use as a basis for the GNU Project, as it was portable and "fairly clean". When the GNU project first started they had an Emacs text editor with Lisp for writing editor commands, a source level debugger , a yacc -compatible parser generator, and

2144-456: The GNU project had completed all of the major operating system utilities, but had not completed their proposed operating system kernel , GNU Hurd . With the release of the Linux kernel , started independently by Linus Torvalds in 1991, and released under the GPLv2 with version 0.12 in 1992, for the first time it was possible to run an operating system composed completely of free software. Though
2211-460: The Internet, or the company a programmer works for may purchase the software. Proceeds from associate members, purchases, and donations support the GNU Project. Copyleft is what helps maintain free use of this software among other programmers. Copyleft gives the legal right to everyone to use, edit, and redistribute programs or programs' code as long as the distribution terms do not change. As
2278-507: The Linux kernel is not part of the GNU project, it was developed using GCC and other GNU programming tools and was released as free software under the GNU General Public License . Most compilation of the Linux kernel is still done with GNU toolchains, but it is currently possible to use the Clang compiler and the LLVM toolchain for compilation. As of present, the GNU project has not released
2345-402: The actual causes of the many issues with Linux on notebooks such as the unnecessary power consumption. Mergers have affected major open-source software. Sun Microsystems (Sun) acquired MySQL AB , owner of the popular open-source MySQL database, in 2008. Oracle in turn purchased Sun in January 2010, acquiring their copyrights, patents, and trademarks. Thus, Oracle became the owner of both
2412-470: The author(s) of the software a royalty or fee for engaging in the listed activities. Although there is an almost complete overlap between free-software licenses and open-source-software licenses, there is a strong philosophical disagreement between the advocates of these two positions. The terminology of FOSS was created to be a neutral on these philosophical disagreements between the Free Software Foundation (FSF) and Open Source Initiative (OSI) and have
2479-456: The combination of GNU and the Linux kernel "GNU/Linux", and asks others to do the same, resulting in the GNU/Linux naming controversy . Most Linux distros combine GNU packages with a Linux kernel which contains proprietary binary blobs . The GNU Free System Distribution Guidelines (GNU FSDG) is a system distribution commitment that explains how an installable system distribution (such as
2546-434: The concept of freely distributed software and universal access to an application's source code . A Microsoft executive publicly stated in 2001 that "Open-source is an intellectual property destroyer. I can't imagine something that could be worse than this for the software business and the intellectual-property business." Companies have indeed faced copyright infringement issues when embracing FOSS. For many years FOSS played
2613-502: The copyright law was extended to computer programs in the United States —previously, computer programs could be considered ideas, procedures, methods, systems, and processes, which are not copyrightable. Early on, closed-source software was uncommon until the mid-1970s to the 1980s, when IBM implemented in 1983 an "object code only" policy, no longer distributing source code. In 1983, Richard Stallman , longtime member of
2680-562: The functionality of software they can bring about changes to the code and, if they wish, distribute such modified versions of the software or often − depending on the software's decision making model and its other users − even push or request such changes to be made via updates to the original software. Manufacturers of proprietary, closed-source software are sometimes pressured to building in backdoors or other covert, undesired features into their software. Instead of having to trust software vendors, users of FOSS can inspect and verify
2747-416: The goal of developing the most efficient software for its users or use-cases while proprietary software is typically meant to generate profits . Furthermore, in many cases more organizations and individuals contribute to such projects than to proprietary software. It has been shown that technical superiority is typically the primary reason why companies choose open source software. According to Linus's law

2814-567: The government charged that bundled software was anticompetitive. While some software was still being provided without monetary cost and license restriction, there was a growing amount of software that was only at a monetary cost with restricted licensing. In the 1970s and early 1980s, some parts of the software industry began using technical measures (such as distributing only binary copies of computer programs ) to prevent computer users from being able to use reverse engineering techniques to study and customize software they had paid for. In 1980,
2881-491: The historical potential of an " economy of abundance " for the new digital world , FOSS may lay down a plan for political resistance or show the way towards a potential transformation of capitalism . According to Yochai Benkler , Jack N. and Lillian R. Berkman Professor for Entrepreneurial Legal Studies at Harvard Law School , free software is the most visible part of a new economy of commons-based peer production of information, knowledge, and culture. As examples, he cites
2948-485: The level of interest in a particular project. However, unlike close-sourced software, improvements can be made by anyone who has the motivation, time and skill to do so. A common obstacle in FOSS development is the lack of access to some common official standards, due to costly royalties or required non-disclosure agreements (e.g., for the DVD-Video format). There is often less certainty of FOSS projects gaining
3015-545: The more people who can see and test a set of code, the more likely any flaws will be caught and fixed quickly. However, this does not guarantee a high level of participation. Having a grouping of full-time professionals behind a commercial product can in some cases be superior to FOSS. Furthermore, publicized source code might make it easier for hackers to find vulnerabilities in it and write exploits. This however assumes that such malicious hackers are more effective than white hat hackers which responsibly disclose or help fix
3082-477: The most popular proprietary database and the most popular open-source database. Oracle's attempts to commercialize the open-source MySQL database have raised concerns in the FOSS community. Partly in response to uncertainty about the future of MySQL, the FOSS community forked the project into new database systems outside of Oracle's control. These include MariaDB , Percona , and Drizzle . All of these have distinct names; they are distinct projects and cannot use
3149-640: The open source licensing and reuse of Commission software (2021/C 495 I/01) was adopted, under which, as a general principle, the European Commission may release software under EUPL or another FOSS license, if more appropriate. There are exceptions though. In May 2022, the Expert group on the Interoperability of European Public Services came published 27 recommendations to strengthen the interoperability of public administrations across
3216-544: The parties stipulated that Google would pay no damages. Oracle appealed to the Federal Circuit , and Google filed a cross-appeal on the literal copying claim. By defying ownership regulations in the construction and use of information—a key area of contemporary growth —the Free/Open Source Software (FOSS) movement counters neoliberalism and privatization in general. By realizing
3283-491: The project. Programmers were encouraged to take part in any aspect of the project that interested them. People could donate funds, computer parts, or even their own time to write code and programs for the project. The origins and development of most aspects of the GNU Project (and free software in general) are shared in a detailed narrative in the Emacs help system. (C-h g runs the Emacs editor command describe-gnu-project .) It
3350-418: The required resources and participation for continued development than commercial software backed by companies. However, companies also often abolish projects for being unprofitable, yet large companies may rely on, and hence co-develop, open source software. On the other hand, if the vendor of proprietary software ceases development, there are no alternatives; whereas with FOSS, any user who needs it still has
3417-484: The right, and the source-code, to continue to develop it themself, or pay a 3rd party to do so. As the FOSS operating system distributions of Linux has a lower market share of end users there are also fewer applications available. "We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable -- one that would give us in-house control. So if we needed to patch, adjust, or adapt, we could." Official statement of
SECTION 50
#17327919044853484-553: The rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in its license . In order to ensure that the entire software of a computer grants its users all freedom rights (use, share, study, modify), even the most fundamental and important part, the operating system (including all its numerous utility programs) needed to be free software. Stallman decided to call this operating system GNU (a recursive acronym meaning " GNU's not Unix! "), basing its design on that of Unix ,
3551-521: The source code themselves and can put trust on a community of volunteers and users. As proprietary code is typically hidden from public view, only the vendors themselves and hackers may be aware of any vulnerabilities in them while FOSS involves as many people as possible for exposing bugs quickly. FOSS is often free of charge although donations are often encouraged. This also allows users to better test and compare software. FOSS allows for better collaboration among various parties and individuals with
3618-518: The trademarked name MySQL. In August 2010, Oracle sued Google , claiming that its use of Java in Android infringed on Oracle's copyrights and patents. In May 2012, the trial judge determined that Google did not infringe on Oracle's patents and ruled that the structure of the Java APIs used by Google was not copyrightable. The jury found that Google infringed a small number of copied files, but
3685-837: The vulnerabilities, that no code leaks or exfiltrations occur and that reverse engineering of proprietary code is a hindrance of significance for malicious hackers. Sometimes, FOSS is not compatible with proprietary hardware or specific software. This is often due to manufacturers obstructing FOSS such as by not disclosing the interfaces or other specifications needed for members of the FOSS movement to write drivers for their hardware - for instance as they wish customers to run only their own proprietary software or as they might benefit from partnerships. While FOSS can be superior to proprietary equivalents in terms of software features and stability, in many cases it has more unfixed bugs and missing features when compared to similar commercial software. This varies per case, and usually depends on
3752-485: The web. Perens subsequently stated that he felt Eric Raymond 's promotion of open-source unfairly overshadowed the Free Software Foundation's efforts and reaffirmed his support for free software. In the following 2000s, he spoke about open source again. From the 1950s and on through the 1980s, it was common for computer users to have the source code for all programs they used, and the permission and ability to modify it for their own use. Software , including source code,
3819-590: 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 the use of the new term and evangelize open-source principles. While the Open Source Initiative sought to encourage the use of the new term and evangelize the principles it adhered to, commercial software vendors found themselves increasingly threatened by
3886-423: Was GNOME, which tackled the same issue from a different angle. It aimed to make a replacement for KDE that had no dependencies on proprietary software. The Harmony project did not make much progress, but GNOME developed very well. Eventually, the proprietary component that KDE depended on ( Qt ) was released as free software. GNOME has since dissociated itself from the GNU Project and the Free Software Foundation, and
3953-519: Was becoming popular but required users to install Qt , which was then proprietary software . To prevent people from being tempted to install KDE and Qt, the GNU Project simultaneously launched two projects. One was the Harmony toolkit . This was an attempt to make a free software replacement for Qt. Had this project been successful, the perceived problem with the KDE would have been solved. The second project
4020-447: Was commonly shared by individuals who used computers, often as public-domain software (FOSS is not the same as public domain software, as public domain software does not contain copyrights ). Most companies had a business model based on hardware sales, and provided or bundled software with hardware, free of charge. By the late 1960s, the prevailing business model around software was changing. A growing and evolving software industry
4087-462: Was competing with the hardware manufacturer's bundled software products; rather than funding software development from hardware revenue, these new companies were selling software directly. Leased machines required software support while providing no revenue for software, and some customers who were able to better meet their own needs did not want the costs of software bundled with hardware product costs. In United States vs. IBM , filed January 17, 1969,
SECTION 60
#17327919044854154-534: Was in the February 1986 edition of the FSF's now-discontinued GNU's Bulletin publication. The canonical source for the document is in the philosophy section of the GNU Project website. As of August 2017 , it is published in 40 languages. To meet the definition of "free software", the FSF requires the software's licensing respect the civil liberties / human rights of what the FSF calls the software user's " Four Essential Freedoms ". The Open Source Definition
4221-438: Was made available under version 2 of the GNU General Public License . Combined with the operating system utilities already developed by the GNU project, it allowed for the first operating system that was free software, commonly known as Linux . The project's current work includes software development, awareness building, political campaigning, and sharing of new material. Richard Stallman announced his intent to start coding
4288-572: Was motivated partly by a desire to avoid GPLv3. The Samba project also switched to GPLv3, so Apple replaced Samba in their software suite by a closed-source, proprietary software alternative. Leemhuis criticizes the prioritization of skilled developers who − instead of fixing issues in already popular open-source applications and desktop environments − create new, mostly redundant software to gain fame and fortune. He also criticizes notebook manufacturers for optimizing their own products only privately or creating workarounds instead of helping fix
4355-528: Was published in March 1985 titled the GNU Manifesto . The manifesto included significant explanation of the GNU philosophy, Free Software Definition and " copyleft " ideas. The FSF takes the position that the fundamental issue Free software addresses is an ethical one—to ensure software users can exercise what it calls " The Four Essential Freedoms ". The Linux kernel , created by Linus Torvalds ,
4422-578: Was released as freely modifiable source code in 1991. Initially, Linux was not released under either a Free software or an Open-source software license. However, with version 0.12 in February 1992, he relicensed the project under the GNU General Public License . FreeBSD and NetBSD (both derived from 386BSD ) were released as Free software when the USL v. BSDi lawsuit was settled out of court in 1993. OpenBSD forked from NetBSD in 1995. Also in 1995, The Apache HTTP Server , commonly referred to as Apache,
4489-527: Was released under the Apache License 1.0 . 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 .
