Xubuntu
Xubuntu () is a Canonical Ltd.–recognized, community-maintained derivative of the Ubuntu operating system. The name ''Xubuntu'' is a portmanteau of ''Xfce'' and ''Ubuntu'', as it uses the Xfce desktop environment, instead of Ubuntu's Unity and GNOME desktop. Xubuntu seeks to provide "a light, stable and configurable desktop environment with conservative workflows" using Xfce components. Xubuntu is intended for both new and experienced Linux users. Rather than explicitly targeting low-powered machines, it attempts to provide "extra responsiveness and speed" on existing hardware. History Xubuntu was originally intended to be released at the same time as Ubuntu 5.10 ''Breezy Badger'', 13 October 2005, but the work was not complete by that date. Instead the Xubuntu name was used for the ''xubuntu-desktop'' metapackage available through the Synaptic Package Manager which installed the Xfce desktop. The first official Xubuntu release, led by Jani Monoses, appeared on 1 June 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lubuntu
Lubuntu ( ) is a lightweight Linux distribution based on Ubuntu and uses the LXQt desktop environment in place of Ubuntu's GNOME desktop. Lubuntu was originally touted as being "lighter, less resource hungry and more energy-efficient", but now aims to be "a functional yet modular distribution focused on getting out of the way and letting users use their computer". Lubuntu originally used the LXDE desktop, but moved to the LXQt desktop with the release of Lubuntu 18.10 in October 2018, due to the slow development of LXDE, losing support for GTK 2 as well as the more active and stable LXQt development without GNOME dependencies. The name ''Lubuntu'' is a portmanteau of ''LXQt'' and ''Ubuntu''. The LXQt name derives from the merger of the LXDE and Razor-qt projects, while the word ''Ubuntu'' means "humanity towards others" in the Zulu and Xhosa languages. Lubuntu received official recognition as a formal member of the Ubuntu family on 11 May 2011, commencing with Lubuntu 11.10, ...

ElementaryOS
elementary OS is a Linux distribution based on Ubuntu LTS. It promotes itself as a "thoughtful, capable, and ethical" replacement to macOS and Windows and has a pay-what-you-want model. The operating system, the desktop environment (called Pantheon), and accompanying applications are developed and maintained by Elementary, Inc. Design philosophy The human interface guidelines of the elementary OS project focus on immediate usability with a gentle learning curve, rather than full-fledged customization. The three core rules the developers set for themselves were "concision", "accessible configuration" and "minimal documentation". Since its inception, elementary OS has received praise and criticism for its design. ''Wired'' claimed that it closely resembled macOS, visually and in user experience. The elementary developers maintain that any similarities are unintentional. Pantheon's main shell is deeply integrated with other elementary OS applications, like Plank (a dock), W ...

Mir (software)
Mir is a computer display server and, recently, a Wayland compositor for the Linux operating system that is under development by Canonical Ltd. It was planned to replace the currently used X Window System for Ubuntu; however, the plan changed and Mutter was adopted as part of GNOME Shell. Mir was announced by Canonical on 4 March 2013 as part of the development of Unity 8, intended as the next generation for the Unity user interface. Four years later Unity 8 was dropped although Mir's development continued for Internet of Things (IoT) applications. Software architecture Mir is built on EGL and uses some of the infrastructure originally developed for Wayland such as Mesa's EGL implementation and Jolla's libhybris. The compatibility layer for X, XMir, is based on XWayland. Other parts of the infrastructure used by Mir originate from Android. These parts include Google's Protocol Buffers, and previously included Android's input stack, which has since been replaced by W ...

GNOME Display Manager
GNOME Display Manager (GDM) is a display manager (a graphical login manager) for the windowing systems X11 and Wayland. The X Window System by default uses the XDM display manager. However, resolving XDM configuration issues typically involves editing a configuration file. GDM allows users to customize or troubleshoot settings without having to resort to a command line. Users can pick their session type on a per-login basis. GDM 2.38.0 is the last version that features customization with themes; subsequent releases do not support themes. Software architecture GDM is a display manager that implements all significant features required for managing attached and remote displays. GDM was written from scratch and does not contain any XDM or X Consortium code. Components GDM comprises the following components: * Chooser – a program used to select a remote host for managing a display remotely on the attached display (gdm-host-chooser) * Greeter – the graphical login window (pro ...

X Display Manager
In the X Window System, an X display manager is a graphical login manager which starts a login session on an X server from the same or another computer. A display manager presents the user with a login screen. A session starts when a user successfully enters a valid combination of username and password. When the display manager runs on the user's computer, it starts the X server before presenting the user the login screen, optionally repeating when the user logs out. In this condition, the DM realizes in the X Window System the functionality of and on character-mode terminals. When the display manager runs on a remote computer, it acts like a telnet server, requesting username and password and starting a remote session. X11 Release 3 introduced display managers in October 1988 with the aim of supporting the standalone X terminals, just coming onto the market. Various display managers continue in routine use to provide a graphical login prompt on standalone computer workst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenGL
OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. Silicon Graphics, Inc. (SGI) began developing OpenGL in 1991 and released it on June 30, 1992; applications use it extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games. Since 2006, OpenGL has been managed by the non-profit technology consortium Khronos Group. Design The OpenGL specification describes an abstract API for drawing 2D and 3D graphics. Although it is possible for the API to be implemented entirely in software, it is designed to be implemented mostly or entirely in hardware. The API is defined as a set of functions which may be called by the client program, alongside a set of named intege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QtWebEngine
Blink is a browser engine developed as part of the Chromium project with contributions from Google, Meta, Microsoft, Opera Software, Adobe, Intel, IBM, Samsung, and others. It was first announced in April 2013. Naming Blink's naming was influenced by the non-standard presentational blink HTML element, which was introduced by Netscape Navigator and supported by Presto- and Gecko-based browsers until August 2013. Blink has, contrary to its name, never functionally supported the element. History Blink is a fork of the WebCore component of WebKit, which was originally a fork of the KHTML and KJS libraries from KDE. It is used in Chrome starting at version 28, Microsoft Edge starting at version 79, Opera (15+), Vivaldi, Brave, Amazon Silk and other Chromium-based browsers and frameworks. Much of WebCore's code was used for features that Google Chrome implemented differently such as sandboxing and the multi-process model. These parts were altered for the Blink fork ...

Reference Implementation
In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is a program that implements all requirements from a corresponding specification. The reference implementation often accompanies a technical standard, and demonstrates what should be considered the "correct" behavior of any other implementation of it. Characteristics and examples Reference implementations of algorithms, for instance cryptographic algorithms, are often the result or the input of standardization processes. In this function they are often dedicated to the public domain with their source code as public domain software. Examples are the first CERN's httpd, Serpent cipher, base64 variants, and SHA-3. The Openwall Project maintains a list of several algorithms with their reference source code in the public domain. A reference implementation may or may not be production quality. For example, the Fraunhofer reference implementation of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Library (computing)
In computer science, a library is a collection of non-volatile memory, non-volatile resources used by computer programs, often for software development. These may include configuration data, documentation, help data, message templates, Code reuse, pre-written code and subroutines, Class (computer science), classes, Value (computer science), values or Data type, type specifications. In OS/360 and successors, IBM's OS/360 and its successors they are referred to as Data set (IBM mainframe)#Partitioned datasets, partitioned data sets. A library is also a collection of implementations of behavior, written in terms of a language, that has a well-defined interface (computing), interface by which the behavior is invoked. For instance, people who want to write a higher-level program can use a library to make system calls instead of implementing those system calls over and over again. In addition, the behavior is provided for reuse by multiple independent programs. A program invokes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
