Dragging And Dropping
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what command is performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer to the object * Press, and hold down, the button on the mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing the button Dragging requires more physical effort than movin ...

Workplace Shell
The Workplace Shell (WPS) is an object-oriented desktop shell (also called desktop environment) produced by IBM's Boca Raton development lab for OS/2 2.0. It is based on Common User Access and made a radical shift away from the Program Manager type interface that earlier versions of OS/2 shared with Windows 3.x or the application-oriented WIMP interface of the Apple Macintosh. The Workplace Shell was also used in OS/2 Warp 3 and Warp 4, and the OS/2-based operating systems eComStation and ArcaOS. IBM originally intended to deliver the Workplace Shell as part of the OfficeVision/2 LAN product, but in 1991 announced plans to release it as part of OS/2 2.0 instead. Although mostly written in C, under the covers the Workplace Shell is implemented as an object-oriented class library, basing on the System Object Model (SOM). The WPS classes are glued together with an interface definition language (IDL). SOM and its IDL was developed by IBM in their Austin, Texas lab. The classe ...

No-code Development Platform
No-code development platforms (NCDPs) allow creating application software through graphical user interfaces and configuration instead of traditional computer programming based on writing code. As with low-code development platforms, it is meant to expedite application development, but unlike low-code, no-code development involves no code writing. This is usually done by offering prebuilt templates for building apps. In the 2010s, both of these types of platforms increased in popularity as companies dealt with a limited supply of competent software developers. No-code development is closely related to visual programming languages. Use No-code tools are often designed with line of business users in mind as opposed to traditional IT. The potential benefits of using a NCDP include: *Agility – NCDPs typically provide some degree of templated user-interface and user experience functionality for common needs such as forms, workflows, and data display allowing creators to expedit ...

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Web Development
Web development is the work involved in developing a website for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing a simple single static page of plain text to complex web applications, electronic businesses, and social network services. A more comprehensive list of tasks to which Web development commonly refers, may include Web engineering, Web design, Web content development, client liaison, client-side/ server-side scripting, Web server and network security configuration, and e-commerce development. Among Web professionals, "Web development" usually refers to the main non-design aspects of building Web sites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills. For larger organizations and businesses, Web development teams can consist of hundreds of people (Web developers) and follow standard methods like Ag ...

Do It Yourself
"Do it yourself" ("DIY") is the method of building, wikt:modification, modifying, or repairing things by oneself without the direct aid of professionals or certified experts. Academic research has described DIY as behaviors where "individuals use Raw material, raw and semi-raw materials and parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g., landscaping)". DIY behavior can be triggered by various motivations previously categorized as market economy, marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity (social science), identity enhancement (Workmanship, craftsmanship, empowerment, community seeking, uniqueness). The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Website Builder
Website builders are tools that typically allow the construction of websites without manual code editing. They fall into two categories: * Online proprietary tools provided by web hosting service companies. These are typically intended for service users to build their own website. Some services allow the site owner to use alternative tools (commercial or open-source) — the more complex of these may also be described as content management systems. * Application software that runs on a personal computing device used to create and edit the pages of a web site and then publish these pages on any host. (These are often considered to be " website design software", rather than "website builders".) History The first website, manually written in HTML, was created on August 6, 1991. Over time, software was created to help design web pages. For example, Microsoft released FrontPage in November 1995. By 1998, Dreamweaver had been established as the industry leader; however, some have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Image Search
Reverse image search is a content-based image retrieval (CBIR) Query string, query technique that involves providing the CBIR system with a sample image that it will then base its search upon; in terms of information retrieval, the sample image is very useful. In particular, reverse image search is characterized by a lack of search terms. This effectively removes the need for a user to guess at keywords or terms that may or may not return a correct result. Reverse image search also allows users to discover content that is related to a specific sample image or the popularity of an image, and to discover manipulated versions and derivative works. A visual search engine is a search engine (computing), search engine designed to search for information on the World Wide Web through a reverse image search. Information may consist of web pages, locations, other images and other types of documents. This type of search engines is mostly used to search on the mobile Internet through an image ...
