Virtual Desktop
In computing, a virtual desktop is a term used with respect to user interfaces, usually within the WIMP paradigm, to describe ways in which the virtual space of a computer's desktop environment is expanded beyond the physical limits of the screen's display area through the use of software. This compensates limits of the desktop area and is helpful in reducing clutter of running graphical applications. There are two major approaches to expanding the virtual area of the screen. Switchable virtual desktops allow the user to make virtual copies of their desktop view-port and switch between them, with open windows existing on single virtual desktops. Another approach is to expand the size of a single virtual screen beyond the size of the physical viewing device. Typically, scrolling/panning a subsection of the virtual desktop into view is used to navigate an oversized virtual desktop. Overview Switching desktops Switchable desktops were designed and implemented at Xerox PA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viewport
A viewport is a polygon viewing region in computer graphics. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. In textbook terminology, the '' world coordinate window'' is the area of interest (meaning what the user wants to visualize) in some application-specific coordinates, e.g. miles, centimeters etc. The word ''window'' as used here should not be confused with the GUI window, i.e. the notion used in window managers. Rather it is an analogy with how a window limits what one can see outside a room. In contrast, the ''viewport'' is an area (typically rectangular) expressed in rendering-device-specific coordinates, e.g. pixels for screen coordinates, in which the objects of interest are going to be rendered. Clipping to the world-coordinates window is usually applied to the objects before they are passed through the window-to-viewport transformation. For a 2D object, the latter transformation is simply a combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sawfish (window Manager)
Sawfish is a window manager for the X Window System. It aims to manage windows in the most flexible and attractive manner possible. It is able to match a window by multiple criteria such as application, size or role, and based on this, can change the window's position, appearance, or behavior. This allows for highly customized window handling such as web browser windows opening full-screen without borders on a secondary monitor, a default terminal emulator window displaying full-screen at the desktop level, and all dialog box windows under a certain size opening on the lower right corner of the main monitor while larger ones are centered. Sawfish uses a Lisp-like scripting language, rep, for all of its code and configuration, making it particularly easy to customize, or program many kinds of behavior, responding to window creation, deletion, or any other changes. There is a GUI configuration utility for users who do not wish to edit configuration files directly. History Sawfi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FVWM
The F Virtual Window Manager is a virtual window manager for the X Window System. Originally a twm derivative, FVWM has evolved into a powerful and highly configurable environment for Unix-like systems. History In 1993, during his work analyzing acoustic signatures for the United States Department of Defense, Robert Nation began hacking twm with the intent of simultaneously reducing memory usage and adding support for virtual desktops. Already known for his rxvt terminal emulator, Nation worked on reducing the memory consumption of his new window manager. Deciding to test FVWM's reception, on June 1, 1993, he bundled it with a rxvt release. In 1994 Rob Nation stopped developing FVWM and made Charles Hines the maintainer. Rob Nation's last release of FVWM was fvwm-1.24r. The post-Rob Nation version of FVWM uses a different configuration file format and has a significantly different architecture. Many Linux distributions, as a result, distributed both fvwm-1.24r and later relea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Workspace
Workspace is a term used in various branches of engineering and economic development. Business development Workspace refers to small premises provided, often by local authorities or economic development agencies, to help new businesses to establish themselves. These typically provide not only physical space and utilities but also administrative services and links to support and finance organizations, as well as peer support among the tenants. A continuum of sophistication ranges through categories such as 'managed workspaces', 'business incubators' and 'business and employment co-operatives'. In cities, they are often set up in buildings that are disused but which the local authority wishes to retain as a landmark. At the larger end of the spectrum are business parks, virtual offices, technology parks and science parks. Technology and software In technology and software, "workspace" is a term used for several different purposes. Software development A workspace is (often) a fil ...

GNOME
A gnome is a mythological creature and diminutive spirit in Renaissance magic and alchemy, first introduced by Paracelsus in the 16th century and later adopted by more recent authors including those of modern fantasy literature. Its characteristics have been reinterpreted to suit the needs of various story tellers, but it is typically said to be a small humanoid that lives underground. Diminutive statues of gnomes introduced as lawn ornaments during the 19th century grew in popularity during the 20th century and came to be known as garden gnomes. History Origins The word comes from Renaissance Latin ''gnomus'', which first appears in ''A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits'' by Paracelsus, published posthumously in Nysa in 1566 (and again in the Johannes Huser edition of 1589–1591 from an autograph by Paracelsus). The term may be an original invention of Paracelsus, possibly deriving the term from Latin ''gēnomos'' (itself represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vtwm
Vtwm (the Virtual Tabbed Window Manager) is an X window manager that was developed from the twm codebase. The first release was in 1990, and it is very much an "old school" window manager, lacking desktop environment features. It added features like xpm icons, autoraising of windows, and a virtual desktop; the latter feature is from where the program takes its name. Later additions include playing sounds in response to window manager events, and Motif-style window decorations in place of the "flat," 2D titlebars commonly associated with twm. Vtwm was one of the first window managers to have an icon manager, a box of clickable windows which mapped to the application windows currently on the desktop. Clicking the entry in the icon manager iconizes or deiconizes the associated application. This behavior is common today in taskbars in many operating systems. Vtwm is released under the MIT license.

Wayland (display Server Protocol)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics ...

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (Berkeley Software Distribution, BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris (operating system), Solaris), Hewlett-Packard, HP/Hewlett Packard Enterprise, HPE (HP-UX), and IBM (IBM AIX, AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are chara ...

Original Amiga Chipset
The Original Chip Set (OCS) is a chipset used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. It was succeeded by the slightly improved Enhanced Chip Set (ECS) and greatly improved Advanced Graphics Architecture (AGA). The original chipset appeared in Amiga models built between 1985 and 1990: the Amiga 1000, Amiga 2000, Amiga CDTV, and Amiga 500. Overview of chips The chipset which gave the Amiga its unique graphics features consists of three main "custom" chips; ''Agnus'', ''Denise'', and ''Paula''. Both the original chipset and the enhanced chipset were manufactured using NMOS logic technology by Commodore's chip manufacturing subsidiary, MOS Technology. According to Jay Miner, the OCS chipset was fabricated in 5 µm manufacturing process while AGA Lisa was implemented in 1.5 µm process. All three custom chips were originally packaged in 48-pin DIPs; later versions of Agnus, known as Fat Ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
