Hydrus
Hydrus is a suite of Windows-based modeling software that can be used for analysis of water flow, heat and solute transport in variably saturated porous media (e.g., soils). HYDRUS suite of software is supported by an interactive graphics-based interface for data-preprocessing, discretization of the soil profile, and graphic presentation of the results. While HYDRUS-1D simulates water flow, solute and heat transport in one-dimension, and is a public domain software, HYDRUS 2D/3D extends the simulation capabilities to the second and third dimensions, and is distributed commercially.

Brick (Electronics)
The word "brick", when used in reference to consumer electronics, describes an electronic device such as a mobile device, game console, or router that, due to corrupted firmware, a hardware problem, or other damage, can no longer function, and thus is "bricked". The device becomes as technologically useful as a brick, hence the name.

Syslog
In computing, syslog /ˈsɪslɒɡ/ is a standard for message logging. It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the type of system generating the message, and is assigned a severity level. Computer system designers may use syslog for system management and security auditing as well as general informational, analysis, and debugging messages. A wide variety of devices, such as printers, routers, and message receivers across many platforms use the syslog standard. This permits the consolidation of logging data from different types of systems in a central repository. Implementations of syslog exist for many operating systems. When operating over a network, syslog uses a client-server architecture where a syslog server listens for and logs messages coming from clients.

HAGGIS
HAGGIS is a high-level reference programming language used primarily to examine Computing Science for Scottish pupils taking SQA courses on the subject. HAGGIS is used as a tool to bridge the gap between pseudocode and typical computer programming. HAGGIS is not based on any one language but a mixture that is intended to allow a pupil familiar with any of the many languages used in classrooms to easily understand the syntactic construct being used in an example. It has multiple programming paradigms of functional, imperative and object-oriented to suit this purpose. There are three separate language definitions, one for each level at which computing is assessed by the SQA; these are proper subsets of each other, so for example any program contained by the National 5 level language is also well-defined at Higher and Advanced Higher levels. Higher includes the definition of procedures and functions and the use of record types and files, while Advanced Higher includes object-orientation. Online HAGGIS interpreters have been developed to provide a way for examiners and teachers to check their programs are correctly defined and behave as expected.

IBM POWER Instruction Set Architecture
The IBM POWER ISA is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by IBM. The name is an acronym for Performance Optimization With Enhanced RISC. The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and supercomputers. These processors are called POWER1 (RIOS-1, RIOS.9, RSC, RAD6000) and POWER2 (POWER2, POWER2+ and P2SC). The ISA evolved into the PowerPC instruction set architecture and was deprecated in 1998 when IBM introduced the POWER3 processor that was mainly a 32/64-bit PowerPC processor but included the POWER ISA for backwards compatibility. The original POWER ISA was then abandoned. PowerPC evolved into the third Power ISA in 2006. IBM continues to develop PowerPC microprocessor cores for use in their application-specific integrated circuit (ASIC) offerings. Many high volume applications embed PowerPC cores.

COHERENS
COHERENS is an open-source hydrodynamic computer model for shallow waters. It was developed in the 1990s by the Royal Belgian Institute of Natural Sciences (RBINS). The name COHERENS is an acronym of COupled Hydrodynamical Ecological model for REgioNal Shelf seas. COHERENS can be used in 1D, 2D or 3D mode and can model both salt waters such as coastal and shelf seas and freshwater basins such as lakes. Applications of the model include obtaining a better understanding of shallow water systems and managing pollution.

French Republican Calendar
The French Republican calendar (French: calendrier républicain français), also commonly called the French Revolutionary calendar (calendrier révolutionnaire français), was a calendar created and implemented during the French Revolution , and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France (which also included decimal time of day, decimalisation of currency, and metrication). It was used in government records in France and other areas under French rule, including Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, Malta, and Italy.

Web Search Engine
A web search engine or Internet search engine is a software system that is designed to carry out web search (Internet search), which means to search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Internet content that is not capable of being searched by a web search engine is generally described as the deep web.

Microsoft TypeScript
Microsoft TypeScript is an open-source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and adds optional static typing to the language. TypeScript is designed for development of large applications and transcompiles to JavaScript. As TypeScript is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs. TypeScript may be used to develop JavaScript applications for both client-side and server-side (Node.js) execution. There are multiple options available for transcompilation. Either the default TypeScript Checker can be used, or the Babel compiler can be invoked to convert TypeScript to JavaScript. TypeScript supports definition files that can contain type information of existing JavaScript libraries, much like C++ header files can describe the structure of existing object files. This enables other programs to use the values defined in the files as if they were statically typed TypeScript entities. There are third-party header files for popular libraries such as jQuery, MongoDB, and D3.js. TypeScript headers for the Node.js basic modules are also available, allowing development of Node.js programs within TypeScript. The TypeScript compiler is itself written in TypeScript and compiled to JavaScript. It is licensed under the Apache 2.0 License. TypeScript is included as a first-class programming language in Microsoft Visual Studio 2013 Update 2 and later, beside C# and other Microsoft languages. An official extension allows Visual Studio 2012 to support TypeScript as well. Anders Hejlsberg, lead architect of C# and creator of Delphi and Turbo Pascal, has worked on the development of TypeScript.
