Elixir (programming Language)
Elixir is a functional, concurrent, general-purpose programming language that runs on the BEAM virtual machine which is also used to implement the Erlang programming language. Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications. Elixir also provides productive tooling and an extensible design. The latter is supported by compile-time metaprogramming with macros and polymorphism via protocols. Elixir is used by companies such as Ramp, PagerDuty, Discord, Brex, E-MetroTel, Pinterest, Moz, Bleacher Report, The Outline, Inverse, Divvy, FarmBot and for building embedded systems. The community organizes yearly events in the United States, Europe, and Japan, as well as minor local events and conferences. History José Valim is the creator of the Elixir programming language, a research and development project created at Plataformatec. His goals were to enable higher extensibility and productivity in the Erla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erlang (programming Language)
Erlang ( ) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs. The Erlang runtime system is designed for systems with these traits: * Distributed * Fault-tolerant * Soft real-time * Highly available, non-stop applications * Hot swapping, where code can be changed without stopping a system. The Erlang programming language has immutable data, pattern matching, and functional programming. The sequential subset of the Erlang language supports eager evaluation, single assignment, and dynamic typing. A normal Erlang application is built out of hundreds of small Erlang processes. It was originally proprietary software within Ericsson, developed by Joe Armstrong, Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metaprogramming
Metaprogramming is a programming technique in which computer programs have the ability to treat other programs as their data. It means that a program can be designed to read, generate, analyze or transform other programs, and even modify itself while running. In some cases, this allows programmers to minimize the number of lines of code to express a solution, in turn reducing development time. It also allows programs a greater flexibility to efficiently handle new situations without recompilation. Metaprogramming can be used to move computations from run-time to compile-time, to generate code using compile time computations, and to enable self-modifying code. The ability of a programming language to be its own metalanguage is called reflection. Reflection is a valuable language feature to facilitate metaprogramming. Metaprogramming was popular in the 1970s and 1980s using list processing languages such as LISP. LISP hardware machines were popular in the 1980s and enabled a ...

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant Programming language implementation, implementation that is treated as a reference implementation, reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming lan ...

Bleacher Report
Bleacher Report (often abbreviated as B/R) is a website that focuses on sport and sports culture. Its headquarters are in San Francisco, with offices in New York City and London. Bleacher Report was acquired by Turner Broadcasting System in August 2012 for $175 million. In March 2018, Bleacher Report and Turner Sports launched B/R Live, a subscription video streaming service featuring live broadcasts of several major sports events. History Founding: 2005–2011 Bleacher Report was formed in 2005 by David Finocchio, Alexander Freund, Bryan Goldberg, and Dave Nemetz—four friends and sports fans who were high school classmates at Menlo School in Atherton, California. Inspired by Ken Griffey Jr, they wanted to start writing about sports. With the help of two old friends, J. B. Long and Ryan Alberti, the company's nucleus took up residence in a Menlo Park office space, in the spring of 2007, for $650 a month. Bleacher Report announced the completion of a round of Series A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinterest
Pinterest is an American image sharing and social media service designed to enable saving and discovery of information (specifically "ideas") on the internet using images, and on a smaller scale, animated GIFs and videos, in the form of pinboards. The site was created by Ben Silbermann, Paul Sciarra, and Evan Sharp, and had 433 million global monthly active users as of July 2022. It is operated by Pinterest, Inc., based in San Francisco. History The idea for ''Pinterest'' emerged from an earlier app created by Ben Silberman and Paul Sciarra called Tote which served as a virtual replacement for paper catalogs. Tote struggled as a business, significantly due to difficulties with mobile payments. At the time, mobile payment technology was not sophisticated enough to enable easy on-the-go transactions, inhibiting users from making many purchases via the app. Tote users were, however, amassing large collections of favorite items and sharing them with other users. The behavior struck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polymorphism (computer Science)
In programming language theory and type theory, polymorphism is the provision of a single interface (computing), interface to entities of different Data type, types or the use of a single symbol to represent multiple different types.: "Polymorphic types are types whose operations are applicable to values of more than one type." The concept is borrowed from a principle in biology where an organism or species can have many different forms or stages. The most commonly recognized major classes of polymorphism are: * ''Ad hoc polymorphism'': defines a common interface for an arbitrary set of individually specified types. * ''Parametric polymorphism'': not specifying concrete types and instead use abstract symbols that can substitute for any type. * ''Subtyping'' (also called ''subtype polymorphism'' or ''inclusion polymorphism''): when a name denotes instances of many different classes related by some common superclass. History Interest in polymorphic type systems developed significa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. (Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters.) Macros often allow positional or keyword parameters that dictate what the conditional assembler program generate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensible
Extensibility is a software engineering and systems design principle that provides for future growth. Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension. Extensions can be through the addition of new functionality or through modification of existing functionality. The principle provides for enhancements without impairing existing system functions. An extensible system is one whose internal structure and dataflow are minimally or not affected by new or modified functionality, for example recompiling or changing the original source code might be unnecessary when changing a system’s behavior, either by the creator or other programmers. Because software systems are long lived and will be modified for new features and added functionalities demanded by users, extensibility enables developers to expand or add to the software’s capabilities and facilitates systematic reuse. Some of its approaches include facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
