XScreenSaver
XScreenSaver is a free and open-source collection of 240+ screensavers for Unix, macOS, iOS and Android operating systems. It was created by Jamie Zawinski in 1992 and is still maintained by him, with new releases coming out several times a year. Platforms The free software and open-source Unix-like operating systems running the X Window System (such as Linux and FreeBSD) use XScreenSaver almost exclusively. On those systems, there are several packages: one for the screen-saving and locking framework, and two or more for the display modes, divided somewhat arbitrarily. On Macintosh systems, XScreenSaver works with the built-in macOS screen saver. On iOS systems, XScreenSaver is a stand-alone app that can run any of the hacks full-screen. On Android systems, the XScreenSaver display modes work either as normal screen savers (which Android sometimes refers to as "Daydreams") or as live wallpapers. There is no official version for Microsoft Windows, and the developer d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jamie Zawinski
Jamie Zawinski (born November 3, 1968), commonly known as jwz, is an American computer programmer, blogger and impresario. He is best known for his role in the creation of Netscape Navigator, Netscape Mail, Lucid Emacs, Mozilla.org, and XScreenSaver. He is also the proprietor of DNA Lounge, a nightclub and live music venue in San Francisco. Biography Zawinski's programming career began at age 16 with Scott Fahlman's Spice Lisp project at Carnegie Mellon University. He then worked at AI startup Expert Technologies, Inc. followed by Robert Wilensky and Peter Norvig's AI research group at UC Berkeley, working on natural language processing. In 1990 he began working at Lucid Inc., first working on Lucid Common Lisp, and then on Lucid's Energize C++ IDE. Lucid decided to use GNU Emacs as the text editor for their IDE due to its free license, popularity, and extensibility, and Zawinski led that project. As Zawinski and the other programmers made fundamental changes to GNU Emacs t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnome-screensaver
Up until GNOME 3.5, GNOME Screensaver was the GNOME project's official screen blanking and locking framework. With the release of GNOME 3.5.5, screen locking functionality became a function of GDM and GNOME Shell by default. History GNOME Screensaver continued to be used by the GNOME Fallback mode until GNOME Fallback was deprecated with the release of GNOME 3.8. GNOME Screensaver continues to be used in the GNOME Flashback session, a continuation of the GNOME Fallback mode. In October 2014, a member of the GNOME Flashback team requested maintainer-ship of GNOME Screensaver which would allow it to officially become part of the GNOME Flashback project. On some GNOME-based Linux distributions, GNOME Screensaver was used instead of the framework that is a part of XScreenSaver. On these systems, the screen savers themselves still came from the XScreenSaver collection, GNOME Screensaver just provided the interface. The GNOME Screensaver interface was designed for improved integrati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screensaver
A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name). Though most modern monitors are not susceptible to this issue (with the notable exception of OLED technology, which has individual pixels vulnerable to burnout), screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device. Some screensaver programs also use otherwise-idle computer resources to do useful work, such as processing for volunteer computing projects. As well as computers, modern television operating systems, media players, and other digital entertainment systems may include optional screensavers.

XMatrix
Matrix digital rain, Matrix code, is the computer code featured in the ''Matrix'' series. The falling green code is a way of representing the activity of the simulated reality environment of the Matrix on screen by kinetic typography. All four ''Matrix'' movies, as well as the spin-off ''The Animatrix'' episodes, open with the code. It is a characteristic mark of the franchise, similar to the opening crawl featured in the ''Star Wars'' franchise. Background In the film, the code that comprises the Matrix itself is frequently represented as downward-flowing green characters. This code uses a custom typeface designed by Simon Whiteley, which includes mirror images of half-width kana characters and Western Latin letters and numerals. In a 2017 interview at CNET, he attributed the design to his wife, who comes from Japan, and added, "I like to tell everybody that The Matrix's code is made out of Japanese sushi recipes". The effect resembles that of older generation green screen d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenGL ES
OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones, tablet computers, video game consoles and PDAs. OpenGL ES is the "most widely deployed 3D graphics API in history". The API is cross-language and multi-platform. The GLU library and the original GLUT are not available for OpenGL ES, freeglut however, supports it. OpenGL ES is managed by the non-profit technology consortium Khronos Group. Vulkan, a next-generation API from Khronos, is made for simpler high performance drivers for mobile and desktop devices. Versions Several versions of the OpenGL ES specification now exist. OpenGL ES 1.0 is drawn up against the OpenGL 1.3 specification, OpenGL ES 1.1 is defined relative to the OpenGL 1. ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Xlib
Xlib (also known as libX11) is an X Window System protocol client library written in the C programming language. It contains functions for interacting with an X server. These functions allow programmers to write programs without knowing the details of the X protocol. Few applications use Xlib directly; rather, they employ other libraries that use Xlib functions to provide widget toolkits: * X Toolkit Intrinsics (Xt) * Athena widget set (Xaw) * Motif * FLTK * GTK * Qt (X11 version) * Tk * SDL (Simple DirectMedia Layer) * SFML (Simple and Fast Multimedia Library) Xlib appeared around 1985, and is used in GUIs for many Unix-like operating systems. A re-implementation of Xlib was introduced in 2007 using XCB. Data types The main types of data in Xlib are the Display structure and the types of the identifiers. Informally, a display is a physical or virtual device where graphical operations are done. The Display structure of the Xlib library contains information about t ...

Sandbox (computer Security)
In computer security, a sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures and/or software vulnerabilities from spreading. The isolation metaphor is taken from the idea of children who do not play well together, so each is given their own sandbox to play in alone. It is often used to execute untested or untrusted programs or code, possibly from unverified or untrusted third parties, suppliers, users or websites, without risking harm to the host machine or operating system. A sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as storage and memory scratch space. Network access, the ability to inspect the host system, or read from input devices are usually disallowed or heavily restricted. In the sense of providing a highly controlled environment, sandboxes may be seen as a specific example of virtualization. Sandboxing is frequently used to test unverified programs th ...

Linux Distributions
A Linux distribution (often abbreviated as distro) is an operating system made from a software collection that includes the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices (for example, OpenWrt) and personal computers (for example, Linux Mint) to powerful supercomputers (for example, Rocks Cluster Distribution). A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System, or, more recently, Wayland), a window manager, and a desktop environment. Most of the included software is free and open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Usually, Linux distributions optionally include some proprietary sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
