Upstart (software)
Upstart is a discontinued event-based replacement for the traditional init daemon—the method by which several Unix-like computer operating systems perform tasks when the computer is started. It was written by Scott James Remnant, a former employee of Canonical Ltd. In 2014, Upstart was placed in maintenance mode, and other init daemons, such as systemd, were recommended in place of Upstart. Ubuntu moved away from Upstart with the release of version 15.04 (''Vivid Vervet'') in favor of migrating to systemd. As of June 2024, there have been no updates released for Upstart since September 2014. Rationale The traditional init process was originally only responsible for bringing the computer into a normal running state after power-on, or gracefully shutting down services prior to shutdown. As a result, the design is strictly synchronous, blocking future tasks until the current one has completed. Its tasks must also be defined in advance, as they are limited to this prep or c ...

Ubuntu Touch
Ubuntu Touch is a mobile version of the Ubuntu operating system, developed by the UBports community. Its user interface is written in Qt, and is designed primarily for touchscreen mobile devices such as smartphones and tablet computers. However, the original goal of convergence was intended to bring Ubuntu Touch to laptops, desktops, IOT devices and TVs for a complete unified user experience. The project was started by Canonical Ltd. but on 5 April 2017 its CEO Mark Shuttleworth announced that Canonical would terminate support due to lack of market interest. It was then adopted by UBports as a community project. The UBports project was seeded by Marius Gripsgård in 2015 and the source code was transferred to the UBports Foundation where it since resides. UBports' mission is to support the collaborative development of Ubuntu Touch and to promote its widespread use. History The Ubuntu Touch project was started in 2011.

List Of Debian Releases
Debian releases do not follow a fixed schedule. Recent releases have been made around every two years by the Debian Project. The most recent version of Debian is Debian version 12, codename "Bookworm". The next up and coming release of Debian is Debian 13, codename "Trixie". Debian always has at least three active branches at any time: "stable", "testing" and "unstable". The stable branch is considered the primary release and what most people refer to when talking about Debian. The testing branch contains packages that have been imported from unstable. Testing has significantly more up-to-date packages than stable and is frozen some time before a release to become the next version of Debian. The unstable release (also known as Sid) is the branch where active development takes place. It is the most volatile version of Debian. When the Debian stable branch is replaced with a newer release, the current stable becomes an "oldstable" release. When the Debian stable branch is replaced ...

ChromiumOS
ChromiumOS (formerly styled as Chromium OS) is a free and open-source Linux distribution designed for running web applications and browsing the World Wide Web. It is the open-source version of ChromeOS, a Linux distribution made by Google. ChromiumOS is based on the Linux kernel, like ChromeOS, but its principal user interface is the Chromium web browser rather than the Google Chrome browser. ChromiumOS also includes the Portage package manager, which was originally developed for Gentoo Linux. Because ChromiumOS and ChromeOS use a browser engine for the user interface, they are oriented toward web applications rather than application software or mobile apps. Google first published the ChromiumOS source code in late 2009. Architecture Chromium's architecture is three-tiered, consisting of "three major components": * The Chromium-based browser and the window manager * System-level software and user-land services: the Linux kernel, drivers, connection manager, and so on * Firmw ...

ChromeOS
ChromeOS, sometimes styled as chromeOS and formerly styled as Chrome OS, is an operating system designed and developed by Google. It is derived from the open-source operating system and uses the Google Chrome web browser as its principal user interface. Google announced the project in July 2009, initially describing it as an operating system where applications and user data would reside in the cloud. ChromeOS was used primarily to run web applications. ChromeOS supports progressive web applications, Android apps from Google Play and Linux applications. History In 2006, Jeff Nelson, a Google employee, created the concept of what would become ChromeOS, initially codenamed "Google OS" as a Linux distribution focused on speed. Early Google OS versions used Firefox as Chrome had not been released, though it switched to Chrome sometime in 2007 due to internal betas being passed around Google. To ascertain marketing requirements, developers relied on informal metrics, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linux Kernel
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), 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 software, free replacement for Unix. Since the late 1990s, it has been included in many Linux distributions, operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android (operating system), Android which is used in many mobile and embedded devices. Most of the kernel code is written in C (programming language), C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly language, assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a Modular programming, modular design such that modules can be inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Distribution
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
