Linux (/ˈlɪnʊks/, LIN-uuks) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries — many of which are provided by the GNU Project — to create a complete operating system.
Linux is one of the most prominent examples of free and open-source software collaboration. While originally developed for x86 based personal computers, it has since been ported to more platforms than any other operating system, and is used on a wide variety of devices including PCs, workstations, mainframes and embedded systems. Linux is the predominant operating system for servers and is also used on all of the world's 500 fastest supercomputers. When combined with Android, which is Linux-based and designed for smartphones, they have the largest installed base of all general-purpose operating systems. (Full article...)

Ubuntu, one of the most popular desktop Linux distributions
A Linux distribution (often abbreviated as distro) 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 the Linux kernel. 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, 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.

Red Hat Enterprise Linux (RHEL) is a commercial open-source Linux distribution developed by Red Hat for the commercial market. Red Hat Enterprise Linux is released in server versions for x86-64, Power ISA, ARM64, and IBM Z and a desktop version for x86-64. Fedora Linux and CentOS Stream serve as its upstream sources. All of Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform.
The first version of Red Hat Enterprise Linux to bear the name originally came onto the market as "Red Hat Linux Advanced Server". In 2003, Red Hat rebranded Red Hat Linux Advanced Server to "Red Hat Enterprise Linux AS" and added two more variants, Red Hat Enterprise Linux ES and Red Hat Enterprise Linux WS. (Full article...) -
openSUSE ( /ˌoʊpənˈsuːzə/) is a free and open-source Linux distribution developed by the openSUSE project. It is offered in two main variations: Tumbleweed, an upstream rolling release distribution, and Leap, a stable release distribution which is sourced from SUSE Linux Enterprise.
The openSUSE project is sponsored by SUSE of Germany; the company released the first version as SUSE Linux in 1994. Its development was opened up to the community in 2005, which marked the creation of openSUSE. The focus of the developers is on creating a stable and user-friendly RPM-based operating system with a large target group for workstations and servers. (Full article...) -
Ubuntu 24.10 "Oracular Oriole"
Ubuntu releases are made semiannually by Canonical Ltd, its developers, using the year and month of the release as a version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) than planned, the version number will change accordingly.
Canonical schedules Ubuntu releases to occur approximately one month after GNOME releases, resulting in each Ubuntu release including a newer version of GNOME. (Full article...) -
In a series of legal disputes between SCO Group and Linux vendors and users, SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell, and Red Hat filed claims against SCO.
On August 10, 2007, a federal district court judge in SCO v. Novell ruled on summary judgment that Novell, not the SCO Group, was the rightful owner of the copyrights covering the Unix operating system. The court also ruled that "SCO is obligated to recognize Novell's waiver of SCO's claims against IBM and Sequent". After the ruling, Novell announced they had no interest in suing people over Unix and stated "We don't believe there is Unix in Linux". The final district court ruling, on November 20, 2008, affirmed the summary judgment, and added interest payments and a constructive trust. (Full article...) -
The Linux kernel is a free and open source, UNIX-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix. Since the late 1990s, it has been included in many operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android which is used in many mobile and embedded devices.
Most of the kernel code is written in C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a modular design such that modules can be integrated as software components – including dynamically loaded. The kernel is monolithic in an architectural sense since the entire OS runs in kernel space. (Full article...) -
In software development, Linus's law is the assertion that "given enough eyeballs, all bugs are shallow".
The law was formulated by Eric S. Raymond in his essay and book The Cathedral and the Bazaar (1999), and was named in honor of Linus Torvalds.
A more formal statement is: "Given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix obvious to someone." Presenting the code to multiple developers with the purpose of reaching consensus about its acceptance is a simple form of software reviewing. Researchers and practitioners have repeatedly shown the effectiveness of reviewing processes in finding bugs and security issues. (Full article...) -
CentOS (/ˈsɛntɒs/, from Community Enterprise Operating System; also known as CentOS Linux) is a discontinued Linux distribution that provided a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board.
The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS. Since version 8, CentOS officially supports the x86-64, ARM64, and POWER8 architectures, and releases up to version 6 also supported the IA-32 architecture. As of December 2015[update], AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture. CentOS 8 was released on 24 September 2019. (Full article...) -
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen-based mobile devices such as smartphones and tablets. It is the world's most widely used operating system due to it being used on most smartphones and tablets outside of iPhones and iPads, which use Apple's iOS and iPadOS, respectively. As of October 2024[update], Android accounts for 45% of the global operating system market, followed by Windows with 26%.
Android has historically been developed by a consortium of developers known as the Open Handset Alliance, but its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. (Full article...) -
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment. Furthermore, some distributions deliberately include only free software. As of 2015[update], over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use. (Full article...)

It also provides engineering and investment in upstream open source projects and support to silicon companies in upstreaming code to be used with their systems-on-a-chip (SoC). Since the 3.10 Linux kernel release, Linaro has consistently been listed in the top ten contributors to the Linux kernel. (Full article...) -
The GNU/Linux naming controversy is a controversy regarding whether computer operating systems that use GNU software and the Linux kernel should be referred to as "GNU/Linux" or "Linux" systems.
Proponents of the term Linux argue that it is far more commonly used by the public and media and that it serves as a generic term for systems that combine that kernel with software from multiple other sources, while proponents of the term GNU/Linux note that GNU alone would be just as good a name for GNU variants which combine the GNU operating system software with software from other sources.

Arch Linux (/ɑːrtʃ/) is an independently developed x86-64 general-purpose Linux distribution that strives to provide the latest stable versions of most software by following a rolling-release model. The default installation is intentionally minimal, and is configured by the user during installation so they may add only what they require.
Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. (Full article...)
