Category: X window managers

* Enlightenment ( window manager ), an X Window System window manager

( Among other things, Presentation Manager placed X, Y coordinate 0, 0 at the bottom left of the screen like Cartesian coordinates, while Windows put 0, 0 at the top left of the screen like most other computer window systems.

IRIX 4. 0, released in 1991, replaced 4Sight with the X Window System ( X11R4 ), the 4Dwm window manager providing a similar look and feel to 4Sight.

IRIX used the Indigo Magic Desktop, which by default used the 4Dwm X window manager with a custom look designed using the Motif widget toolkit.

The graphical mode works even on Unix systems without X or any other window environment, using either SVGALib or the framebuffer of the system's graphics card.

** holonym: Y is a holonym of X if X is a part of Y ( building is a holonym of window )

** meronym: Y is a meronym of X if Y is a part of X ( window is a meronym of building )

A historical example of graphical user interface and applications common to the MIT X Consortium's distribution running under the twm window manager: Xterm | X Terminal, Xbiff, xload and a graphical man page | manual page browser

X does not mandate that the user interface be present – individual client programs known as window managers handle this.

X also lacks support for user-defined stored procedures on the X server, which might have allowed for the dynamic construction of higher order primitives as seen in NeWS, which could reduce bandwidth demands from requiring fewer primitives to be sent, and improve certain types of interaction by removing round trips to the remote X client program in some varieties of menu interactions, picking, window management, and so on.

X is primarily a protocol and graphics primitives definition and it deliberately contains no specification for application user interface design, such as button, menu, or window title bar styles.

Window managers range in sophistication and complexity from the bare-bones ( e. g., twm, the basic window manager supplied with X, or evilwm, an extremely light window manager ) to the more comprehensive desktop environments such as Enlightenment and even to application-specific window managers for vertical markets such as point of sale.

Many users use X with a desktop environment, which, aside from the window manager, includes various applications using a consistent user interface.

For the case of a purely inertial autonavigator consisting of three restrained gyros, a coordinate system is used where the sensitive axis of the X accelerometer is parallel to the east-west direction at the base point, and the Y accelerometer sensitive axis is parallel to the north-south direction at the base point.

These included updates to EtherTalk and TokenTalk, AppleTalk software and LocalTalk hardware for the IBM PC, EtherTalk for Apple's A / UX operating system allowing it to use LaserPrinters and other network resources, and the Mac X. 25 and MacX products.

With the purchase of NeXT and subsequent development of Mac OS X, AppleTalk was strictly a legacy system.

A three dimensional Cartesian coordinate system, with origin O and axis lines X, Y and Z, oriented as shown by the arrows.

In this system, the number ten may be written as " A ", " T " or " X ", and the number eleven as " B " or " E " ( another common notation, introduced by Sir Isaac Pitman, is to use a rotated " 2 " for ten and a reversed " 3 " for eleven ).

A dynamical system may be defined formally, as a measure-preserving transformation of a sigma-algebra, the quadruplet ( X, Σ, μ, τ ).

The quadruple ( X, Σ, μ, τ ), for such a τ, is then defined to be a dynamical system.

Another common workaround is to run GLUT's event loop in a separate thread, although this may vary by operating system, and also may introduce synchronization issues or other problems: for example, the Mac OS X GLUT implementation requires that be run in the main thread.

Let ( X < sub > i </ sub >, f < sub > ij </ sub >) be an inverse system of objects and morphisms in a category C ( same definition as above ).

The inverse limit of this system is an object X in C together with morphisms π < sub > i </ sub >: X → X < sub > i </ sub > ( called projections ) satisfying π < sub > i </ sub >

with the inverse system ( X < sub > i </ sub >, f < sub > ij </ sub >) being understood.

* Let the index set I of an inverse system ( X < sub > i </ sub >, f < sub > ij </ sub >) have a greatest element m. Then the natural projection π < sub > m </ sub >: X → X < sub > m </ sub > is an isomorphism.

X. 25 over the D channel is used at many point-of-sale ( credit card ) terminals because it eliminates the modem setup, and because it connects to the central system over a B channel, thereby eliminating the need for modems and making much better use of the central system's telephone lines.

The kidney also receives input from the parasympathetic nervous system, by way of the renal branches of Vagus nerve ( Cranial nerve X ), the function of this is yet unclear.

Initially, Torvalds wanted to call the kernel he developed Freax ( a combination of " free ", " freak ", and the letter X to indicate that it is a Unix-like system ), but his friend Ari Lemmke, who administered the FTP server where the kernel was first hosted for downloading, named Torvalds ' directory linux.

MySQL works on many different system platforms, including AIX, BSDi, FreeBSD, HP-UX, eComStation, i5 / OS, IRIX, Linux, Mac OS X, Microsoft Windows, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, OS / 2 Warp, QNX, Solaris, Symbian, SunOS, SCO OpenServer, SCO UnixWare, Sanos and Tru64.

Generation X, commonly abbreviated to Gen X, is the generation born after the Western post – World War II baby boom.

: in which X is K, Na, or Ca or less commonly Ba, Rb, or Cs ;

PPP is commonly used as a data link layer protocol for connection over synchronous and asynchronous circuits, where it has largely superseded the older Serial Line Internet Protocol ( SLIP ) and telephone company mandated standards ( such as Link Access Protocol, Balanced ( LAPB ) in the X. 25 protocol suite ).

Both are commonly present on most modern operating systems, including Mac OS X, most distributions of GNU / Linux, OpenBSD, FreeBSD, NetBSD, Solaris and OpenVMS.

* X has been used as a namesake for a generation of humans: Generation X, commonly abbreviated to Gen X.

* X is commonly used as a generic mark ( selecting an item on a form, indicating a location on a map, etc.

Due to the ubiquity of support for X software on Unix, Linux and Mac OS X, X is commonly used to run client applications on personal computers even when there is no need for time-sharing.

People in the computer trade commonly shorten the phrase " X Window System " to " X Window ", " X11 " ( for version 11, used since 1987 ) or simply to " X ".

The fish commonly sold in pet shops is not a pure strain of X. maculatus, but is a hybrid between X. hellerii and X. maculatus.

Frame Relay began as a stripped-down version of the X. 25 protocol, releasing itself from the error-correcting burden most commonly associated with X. 25.

Extracts from the eggs of X. laevis frogs are also commonly used for biochemical studies of DNA replication and repair, as these extracts fully support DNA replication and other related processes in a cell-free environment which allows easier manipulation.

Most commonly X is called locally compact, if every point of X has a compact neighbourhood.
