Xrdb
xrdb (X resource database manager) is a program used for accessing the X resources of a server. Its main use is to read a set of resources from a file and store them in the server at startup. This program can access the resources in both read and write mode. In particular, it can read the resources stored in the server and can store a set of resources on the server, replacing or adding to the previous ones. It can operate either on the general display resources or on the ones specific to a screen. The main use of xrdb is however to load the resources when the X display server is started. For example, the instruction xrdb -load $HOME/.Xresources can be placed in scripts that are executed when the server is started to read the user preferences from the file .Xresources in his home directory. The original version of xrdb was written by Jim Gettys and later rewritten by Bob Scheifler and Phil Karlton. See also * X resources * X Window System The X Window System (X11, or simp ...

Jim Gettys
Jim Gettys (born 15 October 1953) is an American computer programmer. He was involved in multiple computer related projects. Activity Gettys worked at DEC's Cambridge Research Laboratory. Until January 2009, he was the Vice President of Software at the One Laptop per Child project, working on the software for the OLPC XO-1. From 2009 through 2014, he worked at Alcatel-Lucent Bell Labs. Gettys was the co-founder of the group investigating Bufferbloat and the effect it has on the performance of the Internet., and was a core member of the group from 2010-2017, concluding with his publication of "The Blind Man and the Elephant", calling for the wide adoption of Fair Queuing and AQM techniques across the Internet, particularly RFC8290 . Since 2017 he has been investigating the potential for reproducible builds and blockchain technology to make possible a more securely updatable and maintainable IoT infrastructure. He is one of the original developers of the X Window System ... [...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 ...

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 ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a ...

X Resources
In the X Window System, the X resources are parameters of computer programs such as the name of the font used in the buttons, the background color of menus, etc. They are used in conjunction with or as an alternative to command line parameters and configuration files. Format At the X protocol level, resources are strings that are stored in the server and have no special meaning. The syntax and meaning of these strings is given by client libraries and applications. Every X resource specifies a parameter for a program or one of its components. A fully specified resource has the following format: :application.component.subcomponent.subcomponent.attribute: value This resource specifies the value of attribute for the component named component.subcomponent.subcomponent of the program application. Resources are often used for specifying the parameters of widgets created by the application. Since these widgets are arranged in a tree, the sequence of component/subcomponent names is us ...

Display Server
In computing, a windowing system (or window system) is software that manages separately different parts of display screens. It is a type of graphical user interface (GUI) which implements the WIMP (windows, icons, menus, pointer) paradigm for a user interface. Each currently running application is assigned a usually resizable and usually rectangular surface of the display to present its GUI to the user; these windows may overlap each other, as opposed to a tiling interface where they are not allowed to overlap. Usually a window decoration is drawn around each window. The programming of both the window decoration and of available widgets inside of the window, which are graphical elements for direct user interaction, such as sliders, buttons, etc., is eased and simplified through the use of widget toolkits. Technical details The main component of any windowing system is usually called the display server, although alternative denominations such as window server or composit ...
