59-643: TeXnicCenter is a free and open-source IDE for the LaTeX typesetting language. It uses the MiKTeX or TeX Live distributions. It allows the user to type documents in LaTeX and to compile them in PDF , DVI or PS . A menu gives access to precoded elements and environments (formulas, symbols, sections). It also allows for the creation of projects to organize and access the sections and environments of documents, and to insert
118-544: A bibliography (using BibTeX ) and an index (using MakeIndex ). TeXnicCenter was first released in 1999 by Sven Wiegand, it is included in ProTeXt and since version 2.02 it supports UTF-8 encoding. TeXnicCenter has been designed to work with the MiKTeX distribution. After installation, TeXnicCenter recognizes MiKTeX and sets up the paths to command-line compilers bundled with MiKTeX automatically. Similarly, Adobe Acrobat Reader/Professional or Foxit Reader , when available,
177-474: A closed rather than membership-driven organizational model in order to build consensus around its definition. All authority is vested in its Board of Directors, and future boards are appointed by the current board. This governance model has hampered OSI's efforts to achieve other goals not related to the definition. Unlike other free and open-source organizations, it does not develop software, which means that volunteer efforts have been directed elsewhere. In 2008,
236-664: A definition is useful for policymakers, researchers, and technologists. As a campaign of sorts, "open source" was launched in 1998 by Christine Peterson , Jon "maddog" Hall , Larry Augustin , Eric S. Raymond , Bruce Perens , and others. The group adopted the Open Source Definition for open-source software, based on the Debian Free Software Guidelines . They also established the Open Source Initiative (OSI) as
295-689: A free license—and permissive licenses —where derivative works can be released under any license. Software licenses covered by the Open Source Definition also meet the Free Software Definition and vice versa. Both the Free Software Foundation and the OSI share the goal of supporting free and open-source software . The OSI approves certain licenses as compatible with the definition, and maintains
354-427: A list of compliant licenses. New licenses have to submit a formal proposal explaining the rationale for the license, comparison with existing approved licenses, and any legal analysis. The proposal is discussed on the OSI mailing list for at least 30 days before being brought to a vote and approved or rejected by the OSI board. Although the OSI has made an effort to have a transparent process, the approval process has been
413-495: A membership-based structure is to obtain greater financial resources, enabling full-time positions to increase the organization's effectiveness. In March 2021, the OSI organization held a vote for executive director among its members, but the results were annulled because the election was hacked. The election was re-run and Stefano Maffulli appointed its first executive director in September 2021. The Open Source Definition
472-606: 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
531-581: 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
590-440: A source of controversy. Seven approved licenses are particularly recommended by the OSI as "popular, widely used, or having strong communities": In 2022, OSI began work on an Open Source AI Definition (OSAID), inviting select researchers and corporate representatives to make a draft. Even companies with accessible code often do not release the data set used to train the model and impose usage restrictions on what can be done with
649-465: A steward organization for the movement. However, they were unsuccessful in their attempt to secure a trademark for 'open source' to control the use of the term. In 2008, in an apparent effort to reform governance of the organization, the OSI Board invited 50 individuals to join a "Charter Members" group; by 26 July 2008, 42 of the original invitees had accepted the invitations. The full membership of
SECTION 10
#1732790372967708-483: A tower of babel of licenses. We did not design-in license compliance, and we have a tremendous noncompliance problem that isn't getting better. We can't afford to sue our copyright infringers." Eric S. Raymond, another co-founder of the OSI, was later banned from the OSI mailing list in March 2020. He had claimed "OSI has been suborned and is betraying its founding commitment to freedom" the month prior. The release of
767-522: A variety of FOSS projects, including both free software and open-source. Open Source Initiative The Open Source Initiative ( OSI ) is a California public benefit corporation "actively involved in Open Source community-building, education, and public advocacy to promote awareness and the importance of non-proprietary software". The OSI is a California public-benefit nonprofit corporation , with 501(c)(3) tax-exempt status . It adopted
826-448: Is configured as a viewer for the generated PDF documents. TeXnicCenter can tell Acrobat to close an opened PDF file before recompiling it with LaTeX using Dynamic Data Exchange calls. Free and open-source Free and open-source software ( FOSS ) 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
885-460: Is the most widely accepted standard for open-source software . Providing access to the source code is not enough for software to be considered "open-source": it must also allow modification and redistribution under the same terms and all uses, including commercial use. The Open Source Definition requires that ten criteria be met for a license to be approved. It allows both copyleft —where redistribution and derivative works must be released under
944-534: 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
1003-501: 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
1062-682: The Open Source Artificial Intelligence Definition (OSAID) , version 1.0 in November, 2024 opened up new disagreements and considerable ill-feeling, further stirring up ongoing tensions. OpenUK CEO Amanda Brock said it was a mistake as the market will shift and change, noting that it undermines longevity by creating confusion and dispersing resources. She also referred to the absence of dedicated definitions for mobile and cloud, which would have been "very inappropriate". There were questions about whether such
1121-738: 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
1180-665: 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
1239-494: 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
SECTION 20
#17327903729671298-609: 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
1357-588: The Charter Members has never been publicly revealed, and the Charter Members group communicated by way of a closed-subscription mailing list, "osi-discuss", with non-public archives. In 2012, under the leadership of OSI director and then-president Simon Phipps , the OSI began transitioning towards a membership-based governance structure. The OSI initiated an Affiliate Membership program for "government-recognized non-profit charitable and not-for-profit industry associations and academic institutions anywhere in
1416-638: 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),
1475-706: 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
1534-653: 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
1593-449: The OSI attempted to reform its governance, inviting fifty people onto a private mailing list, but this attempt led to no publicly available result. In 2012, the organization again tried to transition towards a membership-based structure, creating affiliate and individual memberships without any formal say over the organization. A plan for corporate membership was also announced, but has not materialized as of 2022 . The motivation for adopting
1652-402: 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
1711-470: 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
1770-434: 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
1829-502: 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

1888-405: The election process. "This week we found a vulnerability in our voting processes that was exploited and had an impact on the outcome of the recent Board Election." No election results or further updates are posted as of June 2021 . In November 2020 the board of directors announced a search for an executive director which was concluded in September 2021 with the appointment of Stefano Maffulli. At
1947-562: 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
2006-416: 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
2065-567: 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,
2124-491: 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
2183-485: 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
2242-545: 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
2301-477: 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
2360-640: 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
2419-544: 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

2478-418: 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
2537-484: 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
2596-625: The same time, the role of president of the board was abandoned in favor of chair of the board. In October 2009, the OSI lost its corporate status, having been suspended by the state of California for failing to submit paperwork on time. In January 2020, founder Bruce Perens left OSI over controversy regarding a new license (the Cryptographic Autonomy License), which had been proposed for the OSI's approval. Later, in August 2020, Perens elaborated on his concerns: "We created
2655-971: 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 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
2714-521: 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
2773-518: 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
2832-455: The trained model. Maffulli said a new definition was necessary because artificial intelligence "is different from regular software and forces all stakeholders to review how the Open Source principles apply to this space". Open Source Definition author Bruce Perens was skeptical about the need to address AI separately, claiming it is going to confuse the open source brand because the existing definition applies to all sofware. The release of
2891-837: 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
2950-485: 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,
3009-460: The world". Subsequently, the OSI announced an Individual Membership program and listed a number of Corporate Sponsors. On November 8, 2013, OSI appointed Patrick Masson as its general manager. From August 2020 to September 2021, Deb Nicholson was the interim general manager. Under the direction of Deborah Nicholson, the interim manager, the voting and election was held with results and then halted and set for re-election due to vulnerabilities in
SECTION 50
#17327903729673068-515: 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
3127-447: 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
3186-462: 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,
3245-534: 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
3304-572: 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
3363-476: 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 ,
3422-657: 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,
3481-527: 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 .
