X.Org Developer’s Conference
The X.Org Foundation is a non-profit corporation chartered to research, develop, support, organize, administrate, standardize, promote, and defend a free and open accelerated graphics stack. This includes, but is not limited to, the following projects: DRM, Mesa 3D, Wayland, and the X Window System and its primary implementation, the X.Org Server. Organization The X.Org Foundation was founded on 22 January 2004. The modern X.Org Foundation came into being when the body that oversaw X standards and published the official reference implementation joined forces with former XFree86 developers. The creation of the Foundation marked a radical change in the governance of X (see the history of the X Window System). Whereas the stewards of X since 1988 (including the previous X.Org, part of The Open Group) had been vendor organizations, the Foundation is led by software developers and using community development on the bazaar model, which relies on outside involvement.

Common Desktop Environment
The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif (software), Motif widget toolkit. It was part of the UNIX 98, UNIX 98 Workstation Product Standard, and was for a long time the Unix desktop associated with commercial Unix workstations. It helped to influence early implementations of successor projects such as KDE and GNOME, which largely replaced CDE following the turn of the century. After a long history as proprietary software, CDE was released as free software on August 6, 2012, under the GNU Lesser General Public License, version 2.0 or later. Since its release as free software, CDE has been ported to Linux and BSD derivatives. History Hewlett-Packard, IBM, SunSoft, Inc., SunSoft, and Unix System Laboratories, USL announced CDE in June 1993 as a joint development within the Common Open Software Environment (COSE) initiative. Each development group contributed its own technology to CDE: * HP contributed the primary envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xephyr
Xephyr is a display server software implementing the X11 display server protocol based on KDrive which targets a window on a host X Server as its framebuffer. It is written by Matthew Allum. Xephyr is an X-on-X implementation and runs on X.Org Server and can work with Glamor. Future versions could make use of libinput. Replacing Xephyr with the xf86-video-dummy and xf86-video-nested drivers in the normal X.Org server is being considered as part of X11R7.8. Features Unlike the similar ''Xnest'', Xephyr supports modern X extensions (even if the host server does not) such as composite, damage, and randr. It uses SHM images and shadow framebuffer updates to provide good performance. It also has a visual debugging mode for observing screen updates. Limitations Xorg's version of Xephyr uses only software rendering for OpenGL, but Feng Haitao has developed forked version of Xephyrwhich can do hardware-accelerated rendering if the underlying X server has the capability.

Pointer (user Interface)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input, such as a text cursor or a mouse pointer. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to ''augment'' human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called a ''bug'', which, in a 3-point form, could have a "drop point and 2 orthogonal wheels". He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xterm
xterm is the standard terminal emulator for the X Window System. It allows users to run programs which require a command-line interface. If no particular program is specified, xterm runs the user's Unix shell, shell. An X display device, display can show one or more user's xterm windows input/output, output at the same time. Each xterm window is a separate Process (computing), process, but all share the same Computer keyboard, keyboard, taking turns as each xterm process acquires Focus (computing), ''focus''. Normally focus switches between X applications as the user moves the pointer (e.g., a mouse cursor) about the screen, but xterm provides options to ''grab focus'' (the ''Secure Keyboard'' feature) as well as accept input events sent without using the keyboard (the ''Allow SendEvents'' feature). Those options have limitations, as discussed in the xterm manual. XTerm originated prior to the X Window System. It was originally written as a stand-alone terminal emulator for ...

Load (computing)
In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods. Unix-style load calculation All Unix and Unix-like systems generate a dimensionless Software metric, metric of three "load average" numbers in the kernel (operating system), kernel. Users can easily query the current result from a Unix shell by running the uptime command: $ uptime 14:34:03 up 10:43, 4 users, load average: 0.06, 0.11, 0.09 The W (Unix), w and top (software), top commands show the same three load average numbers, as do a range of graphical user interface utilities. In operating systems based on the Linux kernel, this information can be easily accessed by reading the procfs, /proc/loadavg file. To explore this kind of infor ...

Histogram
A histogram is a visual representation of the frequency distribution, distribution of quantitative data. To construct a histogram, the first step is to Data binning, "bin" (or "bucket") the range of values— divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping interval (mathematics), intervals of a variable. The bins (intervals) are adjacent and are typically (but not required to be) of equal size. Histograms give a rough sense of the density of the underlying distribution of the data, and often for density estimation: estimating the probability density function of the underlying variable. The total area of a histogram used for probability density is always normalized to 1. If the length of the intervals on the ''x''-axis are all 1, then a histogram is identical to a relative frequency plot. Histograms are sometimes confused with bar charts. In a his ...
