In structural semantics, the actantial model, also called the actantial narrative schema, is a tool used to analyze the action that takes place in a story, whether real or fictional.
 It was developed in 1966 by semiotician Algirdas Julien Greimas.
3D Realms is an American video game publisher and developer based in Garland, Texas.
 It was founded in 1987 as Apogee Software by Scott Miller to publish his game "Kingdom of Kroz".
 Prior to Apogee's founding Miller had released a few games he had developed himself, as well as a couple "packs" of games developed by himself and others, under a shareware distribution model whereby the games were distributed for free in return for donations.
 These games were inconsistently marketed under the name Apogee Software Productions, though after the company was founded they were sold under the Apogee Software name.
 Miller found that the standard shareware model was not viable for his games such as "Beyond the Titanic" (1986) and "Supernova" (1987), and beginning with "Kroz" the company pioneered the "Apogee model" of shareware distribution, wherein games were broken up into segments with the first part released for free to drive interest in the other monetized portions.
Algirdas Julien Greimas (] ; born "Algirdas Julius Greimas"; 9 March 1917 – 27 February 1992), was a French-Lithuanian literary scientist, known among other things for the Greimas Square ("le carré sémiotique").
 He is, along with Roland Barthes, considered the most prominent of the French semioticians. With his training in structural linguistics, he added to the theory of signification and laid the foundations for the Parisian school of semiotics.
 Among Greimas's major contributions to semiotics are the concepts of isotopy, the actantial model, the narrative program, and the semiotics of the natural world.
 He also researched Lithuanian mythology and Proto-Indo-European religion, and was influential in semiotic literary criticism.
InFluid Software is a video game developer and software developer (although mostly the first), established in 1996.
 The company is notorious for their frequent use of horror atmosphere and violence in their games.
 They still uphold the use of the shareware distribution model, trying to remain "old school" as much as possible.
 "Smack Some Smackers" was their most popular and infamous franchise and, besides "Haunted Childhood II", their Internet distribution breakthrough.
 Nowadays, most of their games are freeware, along with the older titles, and the upcoming ones.
V-scale, Vscale, or V scale (with "V" standing for "virtual reality") is a scale of model railroading utilizing self-defining three-dimensional models and a compatible graphics engine to create an alternative modeled world.
 Though it has not been classified or recognized by either the NMRA or MOROP, the term Vscale has gradually taken on widescale de facto use in railfan and model railroading circles.
 V-scale model railroading was created when Japanese game developer Artdink released A-Train in 1985, but it was not widely popularized until Microsoft released "Microsoft Train Simulator" (sometimes referred to as "MSTS") and Australia's Auran/N3V Games released the successful family of Trainz railroad simulators, both in 2001.
 With the ability to enter into the cab of a modeled train consist in a modeled landscape and track system, the 'play' modes of the two simulators gradually established a following among rail enthusiasts.
Lionhead Studios Ltd. was a British video game developer, formerly led by Peter Molyneux.
 It was acquired by Microsoft Studios in April 2006.
 Lionhead started as a breakaway from developer Bullfrog Productions, which was also founded by Molyneux.
 Lionhead's first game was "Black & White", a god game with elements of artificial life and strategy games.
 "Black & White" was published by Electronic Arts in 2001.
 Lionhead Studios is named after Mark Webley's hamster, which died not long after the naming of the studio.
Grand Central Dispatch (GCD) is a technology developed by Apple Inc. to optimize application support for systems with multi-core processors and other symmetric multiprocessing systems.
 It is an implementation of task parallelism based on the thread pool pattern.
 The fundamental idea is to move the management of the thread pool out of the hands of the developer, and closer to the operating system.
 The developer injects "work packages" into the pool oblivious of the pool's architecture.
 This model improves simplicity, portability and performance.
Sansa Framework is a structure to create PHP web applications using the MVC model, it's a web application that must be installed in a server to work, could be installed in a test server or in production server.
 The developer must create a data model and do all the changes the project need and at any time generate the model.
 The generation creates a Database in Mysql server with the same name of the model and a n-tier layer of libraries to handle the Db.
In narrative theory, actant is a term from the actantial model of semiotic analysis of narratives.
 The term also has uses in linguistics, sociology, computer programming theory, and astrology.
PragmaDev Studio is a modeling tool introduced by PragmaDev in 2002.
 It was initially called Real Time Developer Studio or RTDS.
 Its primary objective was to support SDL-RT modeling technology, a mix of the standard SDL from ITU-T and C language.
 Since V5.0 launched on October 7, 2015 RTDS is called PragmaDev Studio.
 Is it organized in four independent modules: Specifier, Developer, Tester and Tracer.
 V5.1 launched on November 29, 2016 introduces a freemium licensing model.
