9wm
9wm is an open source stacking window manager for X11, written by David Hogan (dhog) in 1994 to emulate the Plan 9 Second Edition window manager, 8 . Many later minimalist window managers for X were either inspired by, or directly derived from, 9wm. 9wm takes only 0.4 MB in RAM. ThREADMEfile in the 9wm source distribution describes it like so: Features 9wm does not support a menubar, titlebars, maximize, multiple desktops, desktop shortcuts, theming or a desktop wallpaper. A right click on the root window (desktop) opens a context menu providing window operations (move, resize, delete, hide); a list of up to 32 hidden windows which may be unhidden by selecting from the menu; and a command to launch a terminal emulator (typically 9term). Applications are launched via terminal only, and there is no additional task switching facility. 9wm uses a click to focus model and requires a three-button mouse. There are no keyboard controls or XKeys support. New windows are dra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plan 9 From Bell Labs
Plan 9 from Bell Labs is a distributed operating system which originated from the Computing Science Research Center (CSRC) at Bell Labs in the mid-1980s and built on UNIX concepts first developed there in the late 1960s. Since 2000, Plan 9 has been free and open-source. The final official release was in early 2015. Under Plan 9, UNIX's ''everything is a file'' metaphor is extended via a pervasive network-centric filesystem, and the cursor-addressed, terminal-based I/O at the heart of UNIX-like operating systems is replaced by a windowing system and graphical user interface without cursor addressing, although rc, the Plan 9 shell, is text-based. The name ''Plan 9 from Bell Labs'' is a reference to the Ed Wood 1957 cult science fiction Z-movie '' Plan 9 from Outer Space''. The system continues to be used and developed by operating system researchers and hobbyists. History Plan 9 from Bell Labs was originally developed, starting in the late 1980s, by members of the Computing ...

Cwm (window Manager)
cwm (Calm Window Manager) is a stacking window manager for the X Window System. While it is primarily developed as a part of OpenBSD's base system, portable versions are available on other Unix-like operating systems. History Development of cwm started from patches to evilwm by Marius Aamodt Eriksen. To ease the implementation of new features, cwm was eventually rewritten using some code from 9wm. The last release by the original author came out in August 2005. In April 2007, cwm was imported into OpenBSD source tree. By January 2008, a substantial part of the original source code, including all of the 9wm code, was rewritten. cwm has been distributed with OpenBSD since version 4.2, where it replaced wm2. A third-party Linux port also exists. Description cwm is a stacking window manager oriented towards heavy keyboard usage, small footprint and ease of use. While it lacks explicit virtual desktops functionality, it can be emulated by using the window groups mechanism. c ...

Larswm
larswm is a window manager for the X window system that follows the tiling window manager paradigm. Using ideas from the older 9wm window manager, it features automatic tiling and virtual desktops. It also borrows other ideas, for example a limited form of plumbing, from the Acme development environment. Objects are tiled into non-overlapping areas, instead of using windows that can be stacked, as this approach can result in lower memory and CPU requirements.

8½ (Plan 9)
' is a window system developed for the Plan 9 from Bell Labs operating system by Rob Pike. According to its documentation, the system has ''little graphical fanciness'', a ''fixed user interface'', and depends on a three-button mouse. Like much of the Plan 9 operating system, many operations work by reading and writing to special files. Because of the limitations stemming from its unusual implementation, has been completely rewritten into its successor rio in recent Plan 9 versions.

Focus Stealing
In computing, focus stealing is a mode error occurring when a program not in focus (e.g. minimized or operating in background) places a window in the foreground and redirects all keyboard input to that window. This is considered to be an annoyance or hazard to some users because the program may steal the focus while the user is typing, causing keystrokes to go to the newly focused window, possibly being lost or causing an unintended effect therein. This may be a few keystrokes due to reaction time, or may be more if the user's attention is not on the computer screen, e.g. typing while looking at the keyboard or while reading copy to the side, or if processor lag causes a delay (sometimes of several seconds) between the focus stealing event and the newly focused window displaying on the screen. Security issues Focus stealing can cause damage, as users may, while typing when their attention is away from the screen, inadvertently agree to a program doing something that causes damage. ...

Stacking Window Manager
A stacking window manager (also called floating window manager) is a window manager that draws and allows windows to overlap, without using a compositing algorithm. All window managers that allow the overlapping of windows but are not compositing window managers are considered stacking window managers, although it is possible that not all use exactly the same methods. Other window managers that are not considered stacking window managers are those that do not allow the overlapping of windows, which are called tiling window managers. Stacking window managers allow windows to overlap using clipping to allow applications to write only to the visible parts of the windows they present. The order in which windows are to be stacked is called their z-order. Hybrid window managers Some window managers may be able to treat the foreground window in an entirely different way, by rendering it indirectly, and sending its output to the video card to be added to the outgoing raster.

Context Menu
A context menu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which the menu belongs. Usually the available choices are actions related to the selected object. From a technical point of view, such a context menu is a graphical control element. History Context menus first appeared in the Smalltalk environment on the Xerox Alto computer, where they were called ''pop-up menus''; they were invented by Dan Ingalls in the mid-1970s. Microsoft Office v3.0 introduced the context menu for copy and paste functionality in 1990. Borland demonstrated extensive use of the context menu in 1991 at the Second Paradox Conference in Phoenix Arizona. Lotus 1-2-3/G for OS/2 v1.0 added additional formatting options in 1991 ...

Blit (computer Terminal)
In computing, the Blit was a programmable bitmap graphics terminal designed by Rob Pike and Bart Locanthi Jr. of Bell Labs in 1982. History The Blit programmable bitmap graphics terminal was designed by Rob Pike and Bart Locanthi Jr. of Bell Labs in 1982. The Blit technology was commercialized by AT&T and Teletype. In 1984, the DMD (dot-mapped display) 5620 was released, followed by models 630 MTG (multi-tasking graphics) in 1987 and 730 MTG in 1989. The 5620 used a Western Electric 32100 processor (aka Bellmac 32) and had a 15" green phosphor display with 800×1024×1 resolution (66×88 characters in the initial text mode) interlaced at 30 Hz. The 630 and 730 had Motorola 68000 processors and a 1024×1024×1 monochrome display at 60 Hz (most had amber displays, but some had white or green displays). The folk etymology for the ''Blit'' name is that it stands for ''Bell Labs Intelligent Terminal'', and its creators have also joked that it actually stood for ''Ba ...

Context Switch
In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point, and then restoring a different, previously saved, state. This allows multiple processes to share a single central processing unit (CPU), and is an essential feature of a multitasking operating system. The precise meaning of the phrase "context switch" varies. In a multitasking context, it refers to the process of storing the system state for one task, so that task can be paused and another task resumed. A context switch can also occur as the result of an interrupt, such as when a task needs to access disk storage, freeing up CPU time for other tasks. Some operating systems also require a context switch to move between user mode and kernel mode tasks. The process of context switching can have a negative impact on system performance. Cost Context switches are usually computationally intensive, and much of the design of opera ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Click To Focus
In computing, focus indicates the act of selecting an element of a graphical user interface. Text entered at the keyboard or pasted from a clipboard is sent to the component which has the focus. Moving the focus away from a specific user interface element is known as a blur event in relation to this element. Typically, the focus is withdrawn from an element by giving another element the focus. This means that focus and blur events typically both occur virtually simultaneously, but in relation to different user interface elements, one that gets the focus and one that gets blurred. The concept is similar to a cursor in a text-based environment. However, when considering a graphical interface, there is also a mouse pointer involved. Moving the mouse will typically move the mouse pointer without changing the focus. The focus can usually be changed by clicking on a component that can receive focus with the mouse. Many desktops also allow the focus to be changed with the keyboard. By co ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Three-button Mouse
A mouse button is an electric switch on a computer mouse which can be pressed (“clicked”) to select or interact with an element of a graphical user interface. Mouse buttons are most commonly implemented as miniature snap-action switches (micro switches). The three-button scrollmouse has become the most commonly available design. Users most commonly employ the second button to invoke a contextual menu in the computer's software user interface, which contains options specifically tailored to the interface element over which the pointer currently sits. By default, the primary mouse button sits located on the left-hand side of the mouse, for the benefit of right-handed users; left-handed users can usually reverse this configuration via software. Design In contrast to its motion-tracking mechanism, the mouse's buttons have changed little over the years, varying mostly in shape, number, and placement. A mouse click is the action of pressing (i.e. 'clicking', an onomatopoeia ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...
