Headless Software
Headless software (e.g. "headless Linux",) is software capable of working on a device without a graphical user interface. Such software receives inputs and provides output through other interfaces like network or serial port and is common on servers and embedded devices. The term "headless" is most often used when the ordinary version of the program requires that a graphics card or similar graphical interface device be present. For instance, the absence of a graphic card, mouse or keyboard may cause an initialization process that assumes their presence to fail, or the graphics card may be relied upon to build some offline image that is later served through network. A headless computer (for example, and most commonly, a server) may be missing many of the system libraries that support the display of graphical interfaces. Software that expects these libraries may fail to start or even to compile if such libraries are not present. Headless agents and games Video games typically ...

Graphical User Interface
A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based user interface, text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headless Content Management System
A headless content management system, or headless CMS, is a back end-only web content management system that acts primarily as a content repository. A headless CMS makes content accessible via an API for display on any device, without a built-in front end or presentation layer. Whereas a traditional CMS typically combines a website's content and presentation layers, a headless CMS comprises the content component and focuses on the administrative interface for content creators, the facilitation of content workflows and collaboration, and the organization of content into taxonomies. Cloud-first headless CMSes are those that were also built with a multi-tenant cloud model at their core and whose vendors promote software as a service (SaaS). These vendors promise high availability, scalability, and full management of security, upgrades, and hotfixes on behalf of clients. Headless commerce uses the same setup to separate back-end product management and navigation from the fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headless Computer
A headless computer is a computer system or device that has been configured to operate without a monitor (the missing "head"), keyboard, and mouse. A headless system is typically controlled over a network connection, although some headless system devices require a serial connection to be made over RS-232 for administration of the device. Headless operation of a server is typically employed to reduce operating costs. PC BIOS limitations During bootup, some (especially older) PC BIOS versions will wait indefinitely for a user to press a key before proceeding. If some basic device, such as a video card or keyboard, are not installed or connected, this could effectively halt an unattended system. On more modern systems, the BIOS factory setting will typically be configured to behave this way as well, but this setting can be changed with a BIOS setup utility to proceed without user intervention. Even in cases where a system has been set up to be managed remotely, a local keybo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headless Browser
A headless browser is a web browser without a graphical user interface. Headless browsers provide automated control of a web page in an environment similar to popular web browsers, but they are executed via a command-line interface or using network communication. They are particularly useful for testing web pages as they are able to render and understand HTML the same way a browser would, including styling elements such as page layout, color, font selection and execution of JavaScript and Ajax which are usually not available when using other testing methods. Since version 59 of Google Chrome and version 56 of Firefox, there is native support for remote control of the browser. This made earlier efforts obsolete, notably PhantomJS. Use cases The main use cases for headless browsers are: * Test automation in modern web applications ( web testing) * Taking screenshots of web pages. * Running automated tests for JavaScript libraries. * Automating interaction of web pages.

Secure Shell
The Secure Shell Protocol (SSH Protocol) is a cryptographic network protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution. SSH was designed for Unix-like operating systems as a replacement for Telnet and unsecured remote Unix shell protocols, such as the Berkeley Remote Shell (rsh) and the related rlogin and rexec protocols, which all use insecure, plaintext methods of authentication, like passwords. Since mechanisms like Telnet and Remote Shell are designed to access and operate remote computers, sending the authentication tokens (e.g. username and password) for this access to these computers across a public network in an unsecured way poses a great risk of 3rd parties obtaining the password and achieving the same level of access to the remote system as the telnet user. Secure Shell mitigates this risk through the use of encryption mechanisms that are intended to hide th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OS-level Virtualization
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers ( LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones ( Solaris Containers), virtual private servers ( OpenVZ), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ( FreeBSD jail and chroot). Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares, CPU power, quantifiable hardware capabilities) of that computer. Programs running inside a container can only see the container's contents and devices assigned to the container. On Unix-like operating systems, this feature can be seen as an advanced implementation of the standard chroot mechanism, which changes the apparen ...

Blender (software)
Blender is a Free and open-source software, free and open-source 3D computer graphics software tool set that runs on Microsoft Windows, Windows, macOS, BSD, Haiku (operating system), Haiku, IRIX and Linux. It is used for creating animated films, visual effects, art, 3D printing, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating video games. Blender was used to produce the Academy Awards, Academy Award-winning film ''Flow (2024 film), Flow'' (2024). History Blender was initially developed as an in-house application by the Dutch animation studio NeoGeo (no relation to the Neo Geo, video game brand), and was officially launched on January 2, 1994. Version 1.00 was released in January 1995, with the primary author being the company co-owner and software developer Ton Roosendaal. The name ''Blender'' was inspired by a song by the Swiss electronic band Yello, from the album ''Baby (Yello album), Baby'', which NeoGeo used ...

Synthetic Data
Synthetic data are artificially generated rather than produced by real-world events. Typically created using algorithms, synthetic data can be deployed to validate mathematical models and to train machine learning models. Data generated by a computer simulation can be seen as synthetic data. This encompasses most applications of physical modeling, such as music synthesizers or flight simulators. The output of such systems approximates the real thing, but is fully algorithmically generated. Synthetic data is used in a variety of fields as a filter for information that would otherwise compromise the confidentiality of particular aspects of the data. In many sensitive applications, datasets theoretically exist but cannot be released to the general public; synthetic data sidesteps the privacy issues that arise from using real consumer information without permission or compensation. Usefulness Synthetic data is generated to meet specific needs or certain conditions that may not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frontend And Backend
In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes, and full-stack development refers to mastering both. In the client–server model, the Client (computing), client is usually considered the frontend, handling user-facing tasks, and the Server (computing), server is the backend, managing data and logic. Some presentation tasks may also be performed by the server. Introduction In software architecture, there may be many Abstraction layer, layers between the hardware and End-user (computer science)#End user, end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. Examples E-commerce Website: The ''frontend'' is the user interface (e.g., product pages, search bar), while the ''backend'' processes payments and updates inventory. Bank ...

RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal or PC, and a ''DCE'' ('' data circuit-terminating equipment'' or '' data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used with serial ports and serial cables. It is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them ...
