Graphicacy
Graphicacy is defined as the ability to understand and present information in the form of sketches, photographs, diagrams, maps, plans, charts, graphs and other non-textual formats. The word graphicacy was coined by Balchin and Coleman as representation of the visuo-spatial abilities, they gave their reasons as follows "In the choice of a word to denote the educated counterpart of visual-spatial ability one must first ask the question what exactly does this form of communication involve. It is fundamentally the communication of spatial information that cannot be conveyed adequately by verbal or numerical means,e.g. the plan of a town, the pattern of a drainage network or a picture of a distant place - in other words the whole field of the graphic arts and much of geography cartography, computer-graphics, photography, itself. All of these words contain the syllable "graph" which seemed a logical stem for "graphicacy" which was completed by analogy with literacy, numeracy and articulacy. The modern economy is becoming increasingly reliant on graphics to communicate information. Until recently, words and numbers were the main vehicles for communication, as they have long been relatively easy to produce and distribute in comparison with graphics. Advances in information and communications technology and visualization techniques are increasing the accessibility and usage of graphics, increasing the importance of information graphics. Interpretation of graphics is loosely analogous to the process of reading text, while generation of graphics is the counterpart of writing text. However, these analogies are imperfect, as text and graphics are based on very different symbol systems. For example, whereas text is structured according to formal organisational rules that apply irrespective of the content, this is not the case for graphics. With text structure, the units of information (words) are expected to be organised according to broad conventions (such as being sequenced in orderly rows starting from top left and progressing down the page). However graphics are not subject to a similarly stringent set of structural conventions. Instead, it is the content itself that largely determines the nature of the graphic entities and the way they are arranged. For example, the form and spatial arrangement of the items that comprise the actual subject matter being represented in the graphic are used as the basis for the graphic entities and structure that are displayed in the graphic. This is not the case with written text where the words and their arrangement bear no resemblance to the represented subject matter. Because of these and other fundamental differences between text and graphics, it is appropriate that the processes involved in comprehension and production of graphics are clearly distinguished from those involved in comprehension and production of text.

IBM I Control Language
The IBM i Control Language (CL) is a scripting language for the IBM's IBM i platform (previously called OS/400 when running on AS/400 systems) bearing a resemblance to the IBM Job Control Language and consisting of an ever-expanding set of command objects (*CMD) used to invoke traditional AS/400 programs and/or get help on what those programs do. CL can also be used to create CL programs (congruent to shell scripts) where there are additional commands that provide program-like functionality (IF/ELSE, variable declaration, file input, etc.) Although CL is a scripting language for system administration, it is used mainly to create compiled programs. The use of interpreted CL scripts through the SBMDBJOB command is in fact extremely limited. While thousands of commands were written by IBM developers to perform system level tasks like compiling programs, backing up data, changing system configurations, displaying system object details, or deleting them, commands are not limited to systems level concerns and can be drafted for user applications as well.

VBS1
VBS1 (Virtual Battlefield Systems 1) is a military simulator which relies heavily on modern game technology and is therefore generally referred to as a serious game. The platform is derived from the first-person entertainment game Operation Flashpoint and is developed by Bohemia Interactive Australia. The system enables the practice of small unit military tactics in an interactive multiplayer 3D environment. The platform provides real-time scenario management facilities, customized vehicles and equipment, user-definable mission scenarios, and variable environmental conditions. This combination of military simulator functionality and modern gaming technology proved to be a success and resulted in a broad military customer base. VBS2 is the successor of this platform.

List of Matrices
This page lists some important classes of matrices used in mathematics, science and engineering. A matrix (plural matrices, or less commonly matrixes) is a rectangular array of numbers called entries. Matrices have a long history of both study and application, leading to diverse ways of classifying matrices. A first group is matrices satisfying concrete conditions of the entries, including constant matrices. An important example is the identity matrix given by Further ways of classifying matrices are according to their eigenvalues or by imposing conditions on the product of the matrix with other matrices. Finally, many domains, both in mathematics and other sciences including physics and chemistry have particular matrices that are applied chiefly in these areas.

MIT License
The MIT License is a permissive free software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts only very limited restriction on reuse and has, therefore, high license compatibility. The MIT License is compatible with many copyleft licenses, such as the GNU General Public License (GNU GPL). Any software licensed under the terms of the MIT License can be integrated with software licensed under the terms of the GNU GPL. Unlike copyleft software licenses, the MIT License also permits reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. (As of 2020), the MIT License was the most popular software license found in one analysis, continuing from reports in 2015 that the MIT License was the most popular software license on GitHub. Notable projects that use the MIT License include the X Window System, Ruby on Rails, Nim, Node.js, Lua, and jQuery. Notable companies using the MIT License include Microsoft (.NET Core), Google (Angular), and Meta (React).

List of Folding@home Cores
The distributed-computing project Folding@home uses scientific computer programs, referred to as "cores" or "fahcores", to perform calculations. Folding@home's cores are based on modified and optimized versions of molecular simulation programs for calculation, including TINKER, GROMACS, AMBER, CPMD, SHARPEN, ProtoMol and Desmond. These variants are each given an arbitrary identifier (Core xx). While the same core can be used by various versions of the client, separating the core from the client enables the scientific methods to be updated automatically as needed without a client update.

ADM-3A
The ADM-3A was an influential early video display terminal, introduced in 1976. It was manufactured by Lear Siegler and had a 12-inch screen displaying 12 or 24 lines of 80 characters. It set a new industry low single unit price of $995. Its "dumb terminal" nickname came from some of the original trade publication advertisements. It quickly became commercially successful because of the rapid increase of computer communications speeds, and because of new minicomputer systems released to the market which required inexpensive operator consoles.

Houdini
Houdini is a 3D animation software application developed by Toronto-based SideFX, who adapted it from the PRISMS suite of procedural generation software tools. The procedural tools are used to produce different effects such as complex reflections, animations and particles system. Some of its procedural features have been in existence since 1987. Houdini is most commonly used for the creation of visual effects in film and television. It is used by major VFX companies such as Walt Disney Animation Studios, Pixar, DreamWorks Animation, Double Negative, ILM, MPC, Framestore, Sony Pictures Imageworks, Scanline VFX, Method Studios and The Mill. It has been used in many feature animation productions, including Disney's feature films Fantasia 2000, Frozen, Zootopia and Raya and the Last Dragon; the Blue Sky Studios film Rio, and DNA Productions' Ant Bully. SideFX also publishes Houdini Apprentice, a limited version of the software that is free of charge for non-commercial use.
