LiveCode
LiveCode (formerly Revolution and MetaCard) is a cross-platform rapid application development runtime system inspired by HyperCard. It features the ''LiveCode Script'' (formerly MetaTalk) programming language which belongs to the family of xTalk scripting languages like HyperCard's HyperTalk. The environment was introduced in 2001. The "Revolution" development system was based on the MetaCard engine technology which Runtime Revolution later acquired from MetaCard Corporation in 2003. The platform won the Macworld Annual Editor's Choice Award for "Best Development Software" in 2004. "Revolution" was renamed "LiveCode" in the fall of 2010. "LiveCode" is developed and sold by Runtime Revolution Ltd., based in Edinburgh, Scotland. In March 2015, the company was renamed "LiveCode Ltd.", to unify the company name with the product. In April 2013, a free/open source version 'LiveCode Community Edition 6.0' was published after a successful crowdfunding campaign at Kickstarter. The cod ...

LiveCode (company)
LiveCode Ltd. (formerly Runtime Revolution and Cross Worlds Computing) makes the LiveCode cross-platform development environment (formerly called Revolution) for creating applications that run on iOS, Microsoft Windows, Linux, macOS, Android and Browsers. It is similar to Apple's discontinued HyperCard. History LiveCode began as an expert IDE for MetaCard, a development environment and GUI toolkit originally developed for UNIX development and later ported to support Microsoft Windows and macOS compilation. Runtime Revolution Ltd acquired MetaCard in July 2003 and released subsequent versions under the Revolution brand. MetaCard built on the success of its predecessor HyperCard. Both HyperCard and MetaCard utilized an English-like language that was arguably easier to learn than BASIC. Both RevTalk and HyperCard are development environments within the SmallTalk genre and have similar design attributes. The language has been known by several names including Transcript, RevTalk ...

HyperCard
HyperCard is a application software, software application and software development kit, development kit for Apple Macintosh and Apple IIGS computers. It is among the first successful hypermedia systems predating the World Wide Web. HyperCard combines a flat-file database with a graphical, flexible, user-modifiable interface. HyperCard includes a built-in programming language called HyperTalk for manipulating data and the user interface. This combination of features – a database with simple form layout, flexible support for graphics, and ease of programming – suits HyperCard for many different projects such as rapid application development of applications and databases, interactive applications with no database requirements, command and control systems, and many examples in the demoscene. HyperCard was originally released in 1987 for $49.95 and was included free with all new Macs sold afterwards. It was withdrawn from sale in March 2004, having received its final update in 19 ...

MetaCard
MetaCard is a discontinued cross-platform, commercial HyperCard clone. MetaCard included an IDE, a GUI toolkit and had its own language, MetaTalk. From the MetaCard Corporation website: "The MetaTalk language has all the features common to third-generation languages like C/C++/Java but has a much simpler syntax." Cross Worlds Computing developed applications on the MetaCard platform (e.g., Ten Thumbs Typing Tutor) and developed their own MetaCard IDE called Revolution. They agreed to take over MetaCard development adding the language and runtime to Revolution and changed their name to Runtime Revolution (RunRev). RunRev did not adapt the original MetaCard IDE and it was made available as free and open-source software via a Yahoo! group and a RunRev hosted mailing list. Runtime Revolution changed the name of Revolution to LiveCode and then changed their name to LiveCode LiveCode (formerly Revolution and MetaCard) is a cross-platform rapid application development runtime system i ...

Cross-platform Software
Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy, Qt, GTK, Flutter, NativeScript, Xamarin, Apache Cordova, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to highest, the layers are the li ...

Regular Expressions
A regular expression (shortened as regex or regexp), sometimes referred to as rational expression, is a sequence of character (computing), characters that specifies a pattern matching, match pattern in string (computer science), text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on string (computer science), strings, or for data validation, input validation. Regular expression techniques are developed in theoretical computer science and formal language theory. The concept of regular expressions began in the 1950s, when the American mathematician Stephen Cole Kleene formalized the concept of a regular language. They came into common use with Unix text-processing utilities. Different syntax (programming languages), syntaxes for writing regular expressions have existed since the 1980s, one being the POSIX standard and another, widely used, being the Perl syntax. Regular expressions are used in search engines, in search ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Associative Arrays
In computer science, an associative array, key-value store, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with ''finite'' domain. It supports 'lookup', 'remove', and 'insert' operations. The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. The two major solutions to the dictionary problem are hash tables and search trees..Dietzfelbinger, M., Karlin, A., Mehlhorn, K., Meyer auf der Heide, F., Rohnert, H., and Tarjan, R. E. 1994"Dynamic Perfect Hashing: Upper and Lower Bounds". SIAM J. Comput. 23, 4 (Aug. 1994), 738-761. http://portal.acm.org/citation.cfm?id=182370 It is sometimes also possible to solve the problem using directly addressed arrays, binary search trees, or other more specialized structures.

Hallmark
A hallmark is an official Mark (sign), mark or series of marks struck on items made of metal, mostly to certify the content of noble metals—such as platinum, gold, silver and in some nations, palladium. In a more general sense, the term ''Wiktionary:hallmark, hallmark'' is used to refer to any standard of quality. Not to be confused with responsibility marks that are the marks of the maker. General overview Historically, hallmarks were applied by a trusted party: the "guardians of the craft" or, more recently, by an assay office (). Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal (assay) testing. Hallmarks include information not only about the precious metal and fineness, but the country from which the item was tested and marked. Some hallmarks can reveal even more information, e.g. the assay office, size of the object marked, year the item was hallmarked - referred to as a (also known as date letter). Distinguishment Ha ...

Integrated Development Environment
An integrated development environment (IDE) is a Application software, software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, and a debugger. Some IDEs, such as IntelliJ IDEA, Eclipse (software), Eclipse and Lazarus (software), Lazarus contain the necessary compiler, interpreter (computing), interpreter or both; others, such as SharpDevelop and NetBeans, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class diagram, class hierarchy diagram for use in object-oriented programming, object-oriented software development.
