114-718: Fedora Linux is a Linux distribution developed by the Fedora Project . It was originally developed in 2003 as a continuation of the Red Hat Linux project. It contains software distributed under various free and open-source licenses and aims to be on the leading edge of open-source technologies. It is now the upstream source for CentOS Stream and Red Hat Enterprise Linux . Since the release of Fedora 21 in December 2014, three editions have been made available: personal computer , server and cloud computing . This

228-527: A Wayland compositor such as Sway , KDE 's KWin , or GNOME 's Mutter ), a desktop environment (most commonly GNOME , KDE Plasma , or Xfce ), a sound server (usually either PulseAudio or more recently PipeWire ), and other related programs may be included or installed by the user. Typically, most of the included software is free and open-source software – made available both as binary for convenience and as source code to allow for modifying it. A distro may also include proprietary software that

342-428: A negative or positive liberty . Due to their restrictions on distribution, not everyone considers copyleft licenses to be free. Conversely, a permissive license may provide an incentive to create non-free software by reducing the cost of developing restricted software. Since this is incompatible with the spirit of software freedom, many people consider permissive licenses to be less free than copyleft licenses. There

456-466: A software license whereby the author grants users the aforementioned rights. Software that is not covered by copyright law, such as software in the public domain , is free as long as the source code is also in the public domain, or otherwise available without restrictions. Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing

570-439: A CD with only a small amount of data on it. New users tend to begin by partitioning a hard drive in order to keep their previously installed operating system. The Linux distribution can then be installed on its own separate partition without affecting previously saved data. In a Live CD setup, the computer boots the entire operating system from CD without first installing it on the computer's hard disk. Many distributions have

684-526: A Live CD installer , where the computer boots the operating system from the disk, and it can then be installed on the computer's hard disk, providing a seamless transition from the OS running from the CD to the OS running from the hard disk. Both servers and personal computers that come with Linux already installed are available from vendors including Hewlett-Packard , Dell and System76 . On embedded devices, Linux

798-458: A conscious effort to use a different operating system, and they must either perform the actual installation themselves, or depend on support from a friend, relative, or computer professional. Free software The right to study and modify a computer program entails that the source code —the preferred format for making changes—be made available to users of that program. While this is often called "access to source code" or "public availability",

912-529: A copy of the free application itself. Fees are usually charged for distribution on compact discs and bootable USB drives, or for services of installing or maintaining the operation of free software. Development of large, commercially used free software is often funded by a combination of user donations, crowdfunding , corporate contributions, and tax money. The SELinux project at the United States National Security Agency

1026-512: A distribution, an administrator may create a "distributionless" installation. It is possible to build such systems from scratch, avoiding distributions altogether. One needs a way to generate the first binaries until the system is self-hosting . This can be done via compilation on another system capable of building binaries for the intended target (possibly by cross-compilation ). For example, see Linux From Scratch . In broad terms, Linux distributions may be: The diversity of Linux distributions

1140-561: A fee. The Free Software Foundation encourages selling free software. As the Foundation has written, "distributing free software is an opportunity to raise funds for development. Don't waste it!". For example, the FSF's own recommended license (the GNU GPL ) states that "[you] may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for

1254-450: A fee." Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source." This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release

1368-494: A for-profit, commercial activity or not. Some free software is developed by volunteer computer programmers while other is developed by corporations; or even by both. Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term "free software" rather than " open-source software " (an alternative, yet similar, concept coined in 1998), because

1482-412: A fork of Red Hat Linux launched in 2003, when Red Hat Linux was discontinued so the team could focus on their paid version for servers: Red Hat Enterprise Linux . Red Hat Enterprise Linux was to be Red Hat's only officially supported Linux distribution, while Fedora was to be a community distribution. Red Hat Enterprise Linux branches its releases from versions of Fedora. Before Fedora 7, Fedora Linux

1596-482: A minimal image of Fedora Linux which includes just the bare essentials. This is not to be confused with Fedora Core. It is meant for deployment in cloud computing . It provides Fedora CoreOS images which are optimized minimal images for deploying containers. CoreOS replaced the established Container Linux when it was merged with Project Atomic after its acquisition by Red Hat in January 2018. Similar to Debian blends ,

1710-598: A new SLS-based distribution, Slackware , was released by Patrick Volkerding . Also dissatisfied with SLS, Ian Murdock set to create a free distribution by founding Debian in August 1993, with first public BETA released in January 1994 and first stable version in June 1996. Users were attracted to Linux distributions as alternatives to the DOS and Microsoft Windows operating systems on IBM PC compatible computers, Mac OS on

1824-464: A package are present (and either notify the user to install them, or install them automatically). The package can also be provided as source code to be compiled on the system. Most distributions install packages, including the kernel and other core operating system components, in a predetermined configuration. A few now require or permit configuration adjustments at first install time. This makes installation less daunting, particularly for new users, but

1938-404: A proprietary operating system or by translating proprietary API calls (e.g., calls to Microsoft's Win32 or DirectX APIs) into native Linux API calls. A virtual machine can also be used to run a proprietary OS (like Microsoft Windows) on top of Linux. Computer hardware is usually sold with an operating system other than Linux already installed by the original equipment manufacturer (OEM). In

2052-411: A relatively short life cycle: version X is supported only until 1 month after version X +2 is released and with approximately 6 months between most versions, meaning a version of Fedora is usually supported for at least 13 months, possibly longer. Fedora users can upgrade from version to version without reinstalling. The current release is Fedora 41, which was released on 29 October 2024. Rawhide

2166-670: A result). The name of Fedora derives from the original "Fedora Linux", a volunteer project that provided extra software for the Red Hat Linux distribution, and from the characteristic fedora hat used in Red Hat's "Shadowman" logo. Warren Togami began Fedora Linux in 2002 as an undergraduate project at the University of Hawaii , intended to provide a single repository for well-tested third-party software packages so that non-Red Hat software would be easier to find, develop, and use. The key difference between Fedora Linux and Red Hat Linux

2280-571: A significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies . Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good . Companies that contribute to free software increase commercial innovation . "We migrated key functions from Windows to Linux because we needed an operating system that

2394-498: A small set of licenses. The most popular of these licenses are: The Free Software Foundation and the Open Source Initiative both publish lists of licenses that they find to comply with their own definitions of free software and open-source software respectively: The FSF list is not prescriptive: free-software licenses can exist that the FSF has not heard about, or considered important enough to write about. So it

2508-517: A specific instruction set , while some (such as Gentoo ) are distributed mostly in source code form and must be built before installation. Linus Torvalds developed the Linux kernel and distributed its first version, 0.01, in 1991. Linux was initially distributed as source code only, and later as a pair of downloadable floppy disk images: one bootable and containing the Linux kernel itself, and

2622-716: A specific application or service. Examples of packages are a library for handling the PNG image format, a collection of fonts, and a web browser . The package is typically provided as compiled code, with installation and removal of packages handled by a package management system (PMS) rather than a simple file archiver . Each package intended for such a PMS contains meta-information such as its description, version number, and its dependencies (other packages it requires to run). The package management system evaluates this meta-information to allow package searches, perform automatic upgrades to newer versions, and to check that all dependencies of

2736-448: A variety of security policies, including mandatory access controls , which Fedora adopted early on. Fedora provides a hardening wrapper, and does hardening for all of its packages by using compiler features such as position-independent executable (PIE). Fedora also ships with firewalld as a default firewall . Fedora Workstation comes preinstalled with a wide range of software such as LibreOffice and Firefox . Additional software

2850-507: Is GNOME , and the default user interface is the GNOME Shell . Other desktop environments are available, including KDE Plasma , Xfce , LXQt , LXDE , MATE , Cinnamon , and Budgie as well as window managers including i3 , and Sway . A live media drive can be created using Fedora Media Writer or the dd command, allowing users to try Fedora Linux without writing any changes to their hard drives. Most Fedora Linux editions use

2964-416: Is a Linux distribution that can be booted from removable storage media such as optical discs or USB flash drives , instead of being installed on and booted from a hard disk drive . The portability of installation-free distributions makes them advantageous for applications such as demonstrations, borrowing someone else's computer, rescue operations, or as installation media for a standard distribution. When

3078-762: Is a Linux distribution; others, such as Google engineer Patrick Brady, disagree by noting the lack of support for many GNU tools in Android, including glibc . Other Linux-kernel-based operating systems include Tizen , Mer / Sailfish OS , KaiOS and Amazon's Kindle firmware . Lightweight Linux distributions are those that have been designed with support for older hardware in mind, allowing older hardware to still be used productively, or, for maximum possible speed in newer hardware by leaving more resources available for use by applications. Examples include Tiny Core Linux , Puppy Linux and Slitaz . Other distributions target specific niches, such as: The Free Standards Group

3192-483: Is a variant of Fedora Workstation. It is an atomic desktop operating system. Every Silverblue installation is identical to every other installation of the same version, and it never changes as it is used. The immutable design is intended to make the operating system more stable, less prone to bugs , easier to test and develop, and create a platform for containerized applications as well as container-based software development. Applications and containers are kept separate from

3306-496: Is about 3.67%. Many Linux distributions provide an installation system akin to that provided with other modern operating systems. Other distributions, including Gentoo Linux , provide only the binaries of a basic kernel, compilation tools, and an installer; the installer compiles all the requested software for the specific architecture of the user's computer, using these tools and the software's source code. Distributions are normally segmented into packages . Each package contains

3420-616: Is an operating system that includes the Linux kernel for its kernel functionality. Although the name does not imply product distribution per se, a distro, if distributed on its own, is often obtained via a website intended specifically for the purpose. Distros have been designed for a wide variety of systems ranging from personal computers (for example, Linux Mint ) to servers (for example, Red Hat Enterprise Linux ) and from embedded devices (for example, OpenWrt ) to supercomputers (for example, Rocks Cluster Distribution ). A distro typically includes many components in addition to

3534-617: Is an example of a federally funded free-software project. Proprietary software, on the other hand, tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for

3648-552: Is an organization formed by major software and hardware vendors that aims to improve interoperability between different distributions. Among their proposed standards are the Linux Standard Base , which defines a common ABI and packaging system for Linux, and the Filesystem Hierarchy Standard which recommends a standard filenaming chart, notably the basic directory names found on the root of

3762-801: Is available from the software repositories and can be installed using the DNF package manager or GNOME Software . Additionally, extra repositories can be added to the system, so that software not available in Fedora Linux can be installed easily. Software that is not available via official Fedora repositories, either because it does not meet Fedora's definition of free software or because its distribution may violate US law , can be installed using third-party repositories. Popular third-party repositories include RPM Fusion free and non-free repositories. Fedora also provides users with an easy-to-use build system for creating their own repositories called Copr. Since

3876-466: Is biased by counting more vulnerabilities for the free software systems, since their source code is accessible and their community is more forthcoming about what problems exist as a part of full disclosure , and proprietary software systems can have undisclosed societal drawbacks, such as disenfranchising less fortunate would-be users of free programs. As users can analyse and trace the source code, many more people with no commercial constraints can inspect

3990-545: Is consistent with the intended meaning unlike the term "Open Source". The loan adjective " libre " is often used to avoid the ambiguity of the word "free" in the English language , and the ambiguity with the older usage of "free software" as public-domain software. ( See Gratis versus libre . ) The first formal definition of free software was published by FSF in February 1986. That definition, written by Richard Stallman ,

4104-488: Is credited with tying it to the sense under discussion and starting the free software movement in 1983, when he launched the GNU Project : a collaborative effort to create a freedom-respecting operating system , and to revive the spirit of cooperation once prevalent among hackers during the early days of computing. Free software differs from: For software under the purview of copyright to be free, it must carry

4218-451: Is debate over the security of free software in comparison to proprietary software, with a major issue being security through obscurity . A popular quantitative test in computer security is to use relative counting of known unpatched security flaws. Generally, users of this method advise avoiding products that lack fixes for known security flaws, at least until a fix is available. Free software advocates strongly believe that this methodology

4332-671: Is due to technical, organizational, and philosophical variation among vendors and users. The permissive licensing of free software means that users with sufficient knowledge and interest can customize any existing distribution, or design one to suit their own needs. Rolling Linux distributions are kept current using small and frequent updates . The terms partially rolling and partly rolling (along with synonyms semi-rolling and half-rolling ), fully rolling , truly rolling and optionally rolling are sometimes used by software developers and users. Repositories of rolling distributions usually contain very recent software releases —often

4446-554: Is for servers . It includes the latest data center technologies. This edition does not come with a desktop environment , but one can be installed. From Fedora 28, Server Edition will deliver Fedora Modularity, adding support for alternative update streams for popular software such as Node.js and Go . Images of Fedora Linux tailored to running on Internet of Things devices. It supports x86_64 , aarch64 and armhfp processors . The successor of Fedora Atomic Host (Project Atomic) and Container Linux after Fedora 29, it provides

4560-463: Is like considering the practical advantages of not being handcuffed, in that it is not necessary for an individual to consider practical reasons in order to realize that being handcuffed is undesirable in itself. The FSF also notes that "Open Source" has exactly one specific meaning in common English, namely that "you can look at the source code." It states that while the term "Free Software" can lead to two different interpretations, at least one of them

4674-489: Is not always acceptable. For specific requirements, much software must be carefully configured to be useful, to work correctly with other software, or to be secure, and local administrators are often obliged to spend time reviewing and reconfiguring it. Some (but not all) distributions go to considerable lengths to adjust and customize the software they include, and some provide configuration tools to help users do so. By obtaining and installing everything normally provided in

4788-545: Is not available in source code form, such as a device driver binary . A distro may be described as a particular assortment of application and utility software (various GNU tools and libraries, for example), packaged with the Linux kernel in such a way that its capabilities meet users' needs. The software is usually adapted to the distribution and then combined into software packages by the distribution's maintainers. The software packages are available online in repositories , which are storage locations usually distributed around

4902-443: Is not endorsed by the FSF and does not use Linux-libre, it is also a popular distribution available without kernel blobs by default since 2011. The Linux community uses the term "blob" to refer to all nonfree firmware in a kernel whereas OpenBSD uses the term to refer to device drivers. The FSF does not consider OpenBSD to be blob free under the Linux community's definition of blob. Selling software under any free-software licence

5016-601: Is not in the IT sector choose free software for their Internet information and sales sites, due to the lower initial capital investment and ability to freely customize the application packages. Most companies in the software business include free software in their commercial products if the licenses allow that. Free software is generally available at no cost and can result in permanently lower TCO ( total cost of ownership ) compared to proprietary software . With free software, businesses can fit software to their specific needs by changing

5130-424: Is often referred to as "distro hopping". Virtual machine software such as VirtualBox and VMware Workstation virtualize hardware allowing users to test live media on a virtual machine without installing to the real system. Some websites like DistroWatch offer lists of distributions, and link to screenshots of operating systems as a way to get a first impression of various distributions. Some distributions let

5244-415: Is permissible, as is commercial use. This is true for licenses with or without copyleft . Since free software may be freely redistributed, it is generally available at little or no fee. Free software business models are usually based on adding value such as customization, accompanying hardware, support, training, integration, or certification. Exceptions exist however, where the user is charged to obtain

5358-521: Is possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software, on the other hand, is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet

5472-516: Is sometimes possible on closely related distributions. There are several ways to install a Linux distribution. The most common method of installing Linux is by booting from a live USB memory stick , which can be created by using a USB image writer application and the ISO image, which can be downloaded from various Linux distribution websites. DVD disks, CD disks, network installations and even other hard drives can also be used as "installation media". In

5586-644: Is still maintained today and states that software is free software if people who receive a copy of the software have the following four freedoms. The numbering begins with zero, not only as a spoof on the common usage of zero-based numbering in programming languages, but also because "Freedom 0" was not initially included in the list, but later added first in the list as it was considered very important. Freedoms 1 and 3 require source code to be available because studying and modifying software without its source code can range from highly impractical to nearly impossible. Thus, free software means that computer users have

5700-613: Is summarized at the Debian web site. It is rare that a license announced as being in-compliance with the FSF guidelines does not also meet the Open Source Definition , although the reverse is not necessarily true (for example, the NASA Open Source Agreement is an OSI-approved license, but non-free according to FSF). There are different categories of free software. Proponents of permissive and copyleft licenses disagree on whether software freedom should be viewed as

5814-470: Is targeted at advanced users, testers, and package maintainers, it is capable of being a primary operating system. Users interested in the Rawhide branch often update on a daily basis and help troubleshoot problems. Rawhide users do not have to upgrade between different versions as it follows a rolling release update model. Linux distribution A Linux distribution (often abbreviated as distro )

5928-407: Is the development tree for Fedora. This is a copy of a complete Fedora distribution where new software is added and tested, before inclusion in a later stable release. As such, Rawhide is often more feature rich than the current stable release. In many cases, the software is made of CVS , Subversion or Git source code snapshots which are often actively developed by programmers. Although Rawhide

6042-471: Is typically held in the device's firmware and may or may not be consumer-accessible. Anaconda , one of the more popular installers, is used by Red Hat Enterprise Linux , Fedora (which uses the Fedora Media Writer ) and other distributions to simplify the installation process. Debian, Ubuntu and many others use Debian-Installer . The process of constantly switching between distributions

6156-756: The Apache web server; and the Sendmail mail transport agent. Other influential examples include the Emacs text editor; the GIMP raster drawing and image editor; the X Window System graphical-display system; the LibreOffice office suite; and the TeX and LaTeX typesetting systems. From the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which

6270-536: The Apple Macintosh , and proprietary versions of Unix . Most early adopters were familiar with Unix from work or school. They embraced Linux distributions for their low (or absent) cost, and the availability of the source code for most or all of their software. As of 2024, Linux has become more popular in server and embedded devices markets than in the desktop market. It is used in approximately 58.9% of web servers; its current operating system market share

6384-775: The GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. He developed a free software definition and the concept of " copyleft ", designed to ensure software freedom for all. Some non-software industries are beginning to use techniques similar to those used in free software development for their research and development process; scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under copyleft licenses ( see

6498-693: The Linux kernel and other device drivers motivated some developers in Ireland to launch gNewSense , a Linux-based distribution with all the binary blobs removed. The project received support from the Free Software Foundation and stimulated the creation, headed by the Free Software Foundation Latin America , of the Linux-libre kernel. As of October 2012 , Trisquel is the most popular FSF endorsed Linux distribution ranked by Distrowatch (over 12 months). While Debian

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

6726-559: The RPM package management system and DNF as a tool to manage installed software. DNF uses libsolv, an external dependency resolver. Flatpak is also included by default. The CoreOS and Silverblue editions are designed for operating system-level virtualization . These editions use rpm-ostree (a hybrid transactional image/package system), and traditional RPM (or other package management systems) can be used in containers. Fedora Linux uses Security-Enhanced Linux by default, which implements

6840-425: The software development process , standard releases require significant development effort to keep old versions up-to-date by propagating bug fixes back to the newest branch, versus focusing on the newest development branch . Also, unlike rolling releases, standard releases require more than one code branch to be developed and maintained, which increases the workload of the software developers and maintainers. On

6954-410: The source code was distributed to use these programs. Software was also shared and distributed as printed source code ( Type-in program ) in computer magazines (like Creative Computing , SoftSide , Compute! , Byte , etc.) and books, like the bestseller BASIC Computer Games . By the early 1970s, the picture changed: software costs were dramatically increasing, a growing software industry

7068-400: The 1990s, Linux distributions were installed using sets of floppy disks but this has been abandoned by all major distributions. By the 2000s many distributions offered CD and DVD sets with the vital packages on the first disc and less important packages on later ones. Some distributions, such as Debian also enabled installation over a network after booting from either a set of floppy disks or

7182-495: The Cornell-UVA project could use the name when clearly associated with open source software for digital object repository systems and that Red Hat could use the name when it was clearly associated with open source computer operating systems. In April 2020, project leader Matthew Miller announced that Fedora Workstation would be shipping on select new ThinkPad laptops, thanks to a new partnership with Lenovo . Development of

7296-594: The Fedora Project also distributes custom variations of Fedora Linux called Fedora Labs. These are built with specific sets of software packages, targeting specific interests such as gaming, security, design, robotics, and scientific computing (that includes SciPy , Octave , Kile , Xfig and Inkscape ). The Fedora AOS (Appliance Operating System) was a specialized spin of Fedora Linux with reduced memory footprint for use in software appliances . Appliances are pre-installed, pre-configured, system images. This spin

7410-557: The Free Software Definition cannot rightly be considered free software. Apart from these two organizations, the Debian project is seen by some to provide useful advice on whether particular licenses comply with their Debian Free Software Guidelines . Debian does not publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That

7524-490: The Free Software Foundation (FSF) recommends against thinking in those terms, because it might give the impression that users have an obligation (as opposed to a right) to give non-users a copy of the program. Although the term "free software" had already been used loosely in the past and other permissive software like the Berkeley Software Distribution released in 1978 existed, Richard Stallman

7638-631: 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 included significant explanation of the GNU philosophy, Free Software Definition and " copyleft " ideas. The Linux kernel , started by Linus Torvalds , was released as freely modifiable source code in 1991. The first licence

7752-525: The Internet. Users can easily download and install those applications via a package manager that comes included with most Linux distributions . The Free Software Directory maintains a large database of free-software packages. Some of the best-known examples include Linux-libre , Linux-based operating systems, the GNU Compiler Collection and C library ; the MySQL relational database;

7866-505: The KDE, Sway, and Budgie spins are provided as OSTree-backed immutable spins named Kinoite, Sway Atomic, and Budgie Atomic respectively. In addition to Spins, which are official variants of the Fedora system, the project allows unofficial variants to use the term "Fedora Remix" without asking for further permission, although a different logo (provided) is required. x86-64 and ARM AArch64 are

Commonly, it includes a package manager , an init system (such as systemd , OpenRC , or runit ), GNU tools and libraries , documentation, IP network configuration utilities, the getty TTY setup program, and many more. To provide a desktop experience (most commonly the Mesa userspace graphics drivers) a display server (the most common being the X.org Server , or, more recently,

8094-606: The case of IBM PC compatibles , the OS is usually Microsoft Windows ; in the case of Apple 's Mac computers, it has always been macOS ; Sun Microsystems sold SPARC hardware with the Solaris installed; video game consoles such as the Xbox , PlayStation , Wii , and the Nintendo Switch each have their own proprietary OS. This limits Linux's market share: consumers are unaware that an alternative exists, they must make

8208-410: The changes are available to all Linux distributions . Fedora Linux has a relatively short life cycle: Each version is usually supported for at least 13 months, where version X is supported only until 1 month after version X +2 is released and with approximately 6 months between most versions. Fedora users can upgrade from version to version without reinstalling. The default desktop environment

8322-588: The code and find bugs and loopholes than a corporation would find practicable. According to Richard Stallman, user access to the source code makes deploying free software with undesirable hidden spyware functionality far more difficult than for proprietary software. Some quantitative studies have been done on the subject. In 2006, OpenBSD started the first campaign against the use of binary blobs in kernels . Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts

8436-423: The freedom to cooperate with whom they choose, and to control the software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, the Free Software Foundation says: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in ' free speech ', not as in 'free beer ' ". ( See Gratis versus libre . ) In

8550-412: The goals and messaging are quite dissimilar. According to the Free Software Foundation, "Open source" and its associated campaign mostly focus on the technicalities of the public development model and marketing free software to businesses, while taking the ethical issue of user rights very lightly or even antagonistically. Stallman has also stated that considering the practical advantages of free software

8664-409: The government charged that bundled software was anti-competitive . While some software might always be free, there would henceforth be a growing amount of software produced primarily for sale. 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 or adapt

8778-438: The host system. OS updates are fast and there is no installation stage. With Silverblue, it is also possible to roll back to the previous version of the operating system, if something goes wrong. Fedora Silverblue was previously known as Fedora Atomic Workstation. The descriptive name for this product is image-mode container-based Fedora Workstation based on rpm-ostree, which is clear but unsuitable for branding. The team preferred

8892-421: The late 1990s, other groups published their own definitions that describe an almost identical set of software. The most notable are Debian Free Software Guidelines published in 1997, and The Open Source Definition , published in 1998. The BSD -based operating systems, such as FreeBSD , OpenBSD , and NetBSD , do not have their own formal definitions of free software. Users of these systems generally find

9006-459: The latest stable versions available. They have pseudo-releases and installation media that are simply snapshots of the distribution at the time of the installation image's release. Typically, a rolling-release OS installed from older installation medium can be fully updated after it is installed. Depending on the usage case, there can be pros and cons to both standard release and rolling release software development methodologies . In terms of

9120-435: The need to change the contents of the system's hard disk drive. The website DistroWatch lists many Linux distributions and displays some of the ones that have the most web traffic on the site. The Wikimedia Foundation released an analysis of the browser User Agents of visitors to WMF websites until 2015, which includes details of the most popular Operating System identifiers, including some Linux distributions. Many of

9234-737: The operating system and supporting programs is headed by the Fedora Project, which is composed of a community of developers and volunteers, and also Red Hat employees. The Council is the top-level community leadership and governance body. Other bodies include the Fedora Engineering Steering Committee, responsible for the technical decisions behind the development of Fedora, and Fedora Mindshare Committee which coordinates outreach and non-technical activities, including representation of Fedora Worldwide e.g.: Ambassadors Program, CommOps team and Marketing, Design and Websites Team. Red Hat Linux 9 to Fedora Core 1. Fedora has

9348-797: The operating system is booted from a read-only medium such as a CD or DVD, any user data that needs to be retained between sessions cannot be stored on the boot device but must be written to another storage device, such as a USB flash drive or a hard disk drive. Many Linux distributions provide a "live" form in addition to their conventional form, which is a network-based or removable-media image intended to be used only for installation; such distributions include SUSE , Ubuntu, Linux Mint , MEPIS and Fedora Linux . Some distributions, including Knoppix , Puppy Linux , Devil-Linux, SuperGamer , SliTaz GNU/Linux and dyne:bolic , are designed primarily for live use. Additionally, some minimal distributions can be run directly from as little space as one floppy disk without

9462-450: The other hand, software features and technology planning are easier in standard releases due to a better understanding of upcoming features in the next version(s). Software release cycles can also be synchronized with those of major upstream software projects, such as desktop environments . As for the user experience , standard releases are often viewed as more stable and bug-free since software conflicts can be more easily addressed and

9576-450: The other with a set of GNU utilities and tools for setting up a file system. Since the installation procedure was complicated, especially in the face of growing amounts of available software, distributions sprang up to simplify it. Early distributions included: The two oldest, still active distribution projects started in 1993. The SLS distribution was not well maintained, so in July 1993

9690-522: The pieces for this new desktop over the last few years: OSTree , Flatpak , Flathub , rpm-ostree , and GNOME Software . The ultimate goal of this effort always was to create an image-based variant of the Workstation that is at feature-parity and better suited for certain use cases than the traditional variant. Until the end of 2017, the Silverblue team slowly completed the necessary pieces for

9804-475: The popular distributions are listed below. Several operating systems include the Linux kernel, but have a userland that differs significantly from that of mainstream Linux distributions: Whether such operating systems count as a "Linux distribution" is a controversial topic. They use the Linux kernel, so the Linux Foundation and Chris DiBona , Google's former open-source chief, agree that Android

9918-1051: The primary architectures supported by Fedora. As of release 38, Fedora also supports IBM Power64le , IBM Z ("s390x"), MIPS-64el , MIPS-el and RISC-V as secondary architectures. Fedora 28 was the last release that supported ppc64 and users are advised to move to the little endian ppc64le variant. Fedora 36 was the last release with support for ARM-hfp . The Fedora Project also distributes several other versions with less use cases than mentioned above, like network installers and minimal installation images. They are intended for special cases or expert users that want to have custom installations or configuring Fedora from scratch. In addition, all acceptable licenses for Fedora Linux (including copyright, trademark, and patent licenses) must be applicable not only to Red Hat or Fedora, but also to all recipients downstream. This means that any "Fedora-only" licenses, or licenses with specific terms that Red Hat or Fedora meets but that other recipients would not are not acceptable (and almost certainly non-free, as

10032-430: The project name Silverleaf, but could not secure that name for various reasons. Therefore, it was named Silverblue, though the logo still retains the impression of a leaf. The long-term goal for this effort is to transform Fedora Workstation into an image-based system where applications are separate from the OS, and updates are atomic. Red Hat engineers, along with independent free software contributors have built most of

10146-600: The release of Fedora 25, the operating system defaults to the Wayland display server protocol, which replaced the X Window System . Fedora Linux uses Anaconda as the system installer . Beginning with Fedora 21, it is available in three editions, expanded to five editions as of version 37. It targets users who want a reliable, user-friendly, and powerful operating system for their laptop or desktop computer. It comes with GNOME by default but other desktops can be installed or can be directly installed as Spins . Silverblue

10260-448: The rolling release model can have advantages in timely security updates, fixing system or application security bugs and vulnerabilities , that standard releases may have to wait till the next release for or patch in various versions. In a rolling release distribution, where the user has chosen to run it as a highly dynamic system, the constant flux of software packages can introduce new unintended vulnerabilities. A "live" distribution

10374-511: The same set of software to be acceptable, but sometimes see copyleft as restrictive. They generally advocate permissive free software licenses , which allow others to use the software as they wish, without being legally forced to provide the source code. Their view is that this permissive approach is more free. The Kerberos , X11 , and Apache software licenses are substantially similar in intent and implementation. There are thousands of free applications and many operating systems available on

10488-435: The shift in climate surrounding the computer world and its users. In his initial declaration of the project and its purpose, he specifically cited as a motivation his opposition to being asked to agree to non-disclosure agreements and restrictive licenses which prohibited the free sharing of potentially profitable in-development software, a prohibition directly contrary to the traditional hacker ethic . Software development for

10602-461: The software applications as they saw fit. In 1980, copyright law was extended to computer programs. In 1983, Richard Stallman , one of the original authors of the popular Emacs program and a longtime member of the hacker community at the MIT Artificial Intelligence Laboratory , announced the GNU Project , the purpose of which was to produce a completely non-proprietary Unix-compatible operating system, saying that he had become frustrated with

10716-507: The software stack more thoroughly tested and evaluated, during the software development cycle. For this reason, they tend to be the preferred choice in enterprise environments and mission-critical tasks. However, rolling releases offer more current software which can also provide increased stability and fewer software bugs along with the additional benefits of new features, greater functionality, faster running speeds, and improved system and application security . Regarding software security ,

10830-443: The software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage. Such an agreement is made separately from the free software license. A report by Standish Group estimates that adoption of free software has caused

10944-514: The software, and this results in reliance on the publisher to provide updates, help, and support. ( See also vendor lock-in and abandonware ). Users often may not reverse engineer , modify, or redistribute proprietary software. Beyond copyright law, contracts and a lack of source code, there can exist additional obstacles keeping users from exercising freedom over a piece of software, such as software patents and digital rights management (more specifically, tivoization ). Free software can be

11058-411: The source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and free software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM (IBM acquired RedHat in 2019), which do substantial commercial business in the development of free software. Free software played

11172-435: The tree of any Linux filesystem. Those standards, however, see limited use, even among the distributions developed by members of the organization. The diversity of Linux distributions means that not all software runs on all distributions, depending on what libraries and other system attributes are required. Packaged software and software repositories are usually specific to a particular distribution, though cross-installation

11286-467: The user install Linux on top of their current system, such as WinLinux or coLinux . Linux is installed to the Windows hard disk partition, and can be started from inside Windows itself. Virtual machines (such as VirtualBox or VMware ) also make it possible for Linux to be run inside another OS. The VM software simulates a separate computer onto which the Linux system is installed. After installation,

11400-495: The users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs , they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free. The issue of binary blobs in

11514-402: The version meant for cloud computing . Fedora is a trademark of Red Hat, Inc. Red Hat's application for trademark status for the name "Fedora" was disputed by Cornell University and the University of Virginia Library , creators of the unrelated Fedora Commons digital repository management software. The issue was resolved and the parties settled on a co-existence agreement that stated that

11628-644: The virtual machine can be booted as if it were an independent computer. Various tools are also available to perform full dual-boot installations from existing platforms without a CD, most notably: Some specific proprietary software products are not available in any form for Linux. As of September 2015, the Steam gaming service has over 1,500 games available on Linux, compared to 2,323 games for Mac and 6,500 Windows games. Emulation and API-translation projects like Wine and CrossOver make it possible to run non-Linux-based software on Linux systems, either by emulating

11742-478: The vision of an immutable image-based OS with independent applications: Wayland, flatpak, and rpm-ostree support in GNOME Software, etc. During the same time, Project Atomic has added new features like package layering to rpm-ostree and added rpm-ostree support to Anaconda . Fedora also supports more immutable editions, including Sway Atomic, Budgie Atomic, and Kinoite for KDE Plasma . Its target usage

11856-724: The world. Beside "glue" components, such as the distribution installers (for example, Debian-Installer and Anaconda ) and the package management systems, very few packages are actually written by a distribution's maintainers. Distributions have been designed for a wide range of computing environments, including desktops , servers , laptops , netbooks , mobile devices (phones and tablets), and embedded systems . There are commercially backed distributions, such as Fedora Linux ( Red Hat ), openSUSE ( SUSE ) and Ubuntu ( Canonical Ltd. ), and entirely community-driven distributions, such as Debian , Slackware , Gentoo and Arch Linux . Most distributions come ready-to-use and prebuilt for

11970-620: Was a proprietary software licence. However, 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. 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,

12084-409: Was called Fedora Core after the name of one of the two main software repositories - Core and Extras. Fedora Core contained all the base packages that were required by the operating system, as well as other packages that were distributed along with the installation CD / DVDs , and was maintained only by Red Hat developers. Fedora Extras, the secondary repository that had been included since Fedora Core 3,

12198-455: Was community-maintained and not distributed along with the installation CD/DVDs. Upon the release of Fedora 7, the distinction between Fedora Core and Fedora Extras was eliminated. Since the release of Fedora 21, as an effort to bring modularization to the Fedora distribution and make development more agile, three different versions are available: Workstation , focused on the personal computer , Server and Atomic for servers , Atomic being

12312-402: 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,

12426-658: Was expanded to five editions for containerization and Internet of Things (IoT) as of the release of Fedora 37 in November 2022. A new version of Fedora Linux is released every six months. As of February 2016, Fedora Linux has an estimated 1.2 million users, and is also the distribution used by Linus Torvalds , creator of the Linux kernel (as of May 2020). Fedora has a reputation for focusing on innovation, integrating new technologies early on and working closely with upstream Linux communities. Making changes upstream instead of specifically for Fedora Linux ensures that

12540-579: Was intended to make it easier for anyone (developers, independent software vendors (ISV), original equipment manufacturers (OEM), etc.) to create and deploy virtual appliances . The Fedora project officially distributes different variations called "Fedora Spins" which are Fedora Linux with different desktop environments (GNOME is the default desktop environment). The current official spins, as of Fedora 40, are KDE Plasma , Xfce , LXQt , MATE (with Compiz ), Cinnamon , LXDE , SoaS , i3 , Phosh (for use on PinePhone ), Budgie , and Sway . In addition,

12654-476: Was released under the Apache License 1.0 . All free-software licenses must grant users all the freedoms discussed above. However, unless the applications' licenses are compatible, combining programs by mixing source code or directly linking binaries is problematic, because of license technicalities . Programs indirectly connected together may avoid this problem. The majority of free software falls under

12768-679: 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 the United Space Alliance , which manages the computer systems for the International Space Station (ISS), regarding their May 2013 decision to migrate ISS computer systems from Windows to Linux The economic viability of free software has been recognized by large corporations such as IBM , Red Hat , and Sun Microsystems . Many companies whose core business

12882-402: Was that Fedora's repository development would be collaborative with the global volunteer community. The original Fedora Linux was eventually absorbed into the Fedora Project, carrying with it this collaborative approach. The Fedora Project is sponsored primarily by Red Hat with additional support and sponsors from other companies and organizations. Fedora Linux, then known as "Fedora Core", was

12996-407: Was typically public-domain software . Software was commonly shared by individuals who used computers and by hardware manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, SHARE , were formed to facilitate exchange of software. As software was often written in an interpreted language such as BASIC ,
