HOPL
History of Programming Languages (HOPL) is an infrequent ACM SIGPLAN conference. Past conferences were held in 1978, 1993, and 2007. The fourth conference was originally intended to take place in June 2020, but was postponed to 2021. HOPL I HOPL I was held June 1 – 3, 1978 in Los Angeles, California. Jean E. Sammet was both the general and program committee chair. John A. N. Lee was the administrative chair. Richard L. Wexelblat was the proceedings chair. From Sammet's introduction: The HOPL Conference "is intended to consider the technical factors which influenced the development of certain selected programming languages." The languages and presentations in the first HOPL were by invitation of the program committee. The invited languages must have been created and in use by 1967. They also must have remained in use in 1977. Finally, they must have had considerable influence on the field of computing. The papers and presentations went through extensive review by the program c ... [...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 Virding, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AppleScript
AppleScript is a scripting language created by Apple Inc. that facilitates automated control over scriptable Mac applications. First introduced in System 7, it is currently included in all versions of macOS as part of a package of system automation tools. The term "AppleScript" may refer to the language itself, to an individual script written in the language, or, informally, to the macOS Open Scripting Architecture that underlies the language. Overview AppleScript is primarily a scripting language developed by Apple to do inter-application communication (IAC) using Apple events. AppleScript is related to, but different from, Apple events. Apple events are designed to exchange data between and control other applications in order to automate repetitive tasks. AppleScript has some processing abilities of its own, in addition to sending and receiving Apple events to applications. AppleScript can do basic calculations and text processing, and is extensible, allowing the use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Programming
In computer science, functional programming is a programming paradigm where programs are constructed by Function application, applying and Function composition (computer science), composing Function (computer science), functions. It is a declarative programming paradigm in which function definitions are Tree (data structure), trees of Expression (computer science), expressions that map Value (computer science), values to other values, rather than a sequence of Imperative programming, imperative Statement (computer science), statements which update the State (computer science), running state of the program. In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local Identifier (computer languages), identifiers), passed as Parameter (computer programming), arguments, and Return value, returned from other functions, just as any other data type can. This allows programs to be written in a Declarative programming, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haskell (programming Language)
Haskell () is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial applications, Haskell has pioneered a number of programming language features such as type classes, which enable type-safe operator overloading, and monadic IO. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry. Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC continues to expand Haskell via language extensions. Haskell is used in academia and industry. , Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.

Lua (programming Language)
Lua ( ; from meaning ''moon'') is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications. Lua is cross-platform, since the interpreter of compiled bytecode is written in ANSI C, and Lua has a relatively simple C API to embed it into applications. Lua originated in 1993 as a language for extending software applications to meet the increasing demand for customization at the time. It provided the basic facilities of most procedural programming languages, but more complicated or domain-specific features were not included; rather, it included mechanisms for extending the language, allowing programmers to implement such features. As Lua was intended to be a general embeddable extension language, the designers of Lua focused on improving its speed, portability, extensibility, and ease-of-use in development. History Lua was created in 1993 by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes, membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Self (programming Language)
is an object-oriented programming language based on the concept of ''prototypes''. Self began as a dialect of Smalltalk, being dynamically typed and using just-in-time compilation (JIT) as well as the prototype-based approach to objects: it was first used as an experimental test system for language design in the 1980s and 1990s. In 2006, Self was still being developed as part of the Klein project, which was a Self virtual machine written fully in Self. The latest version is 2017.1 released in May 2017. Several just-in-time compilation techniques were pioneered and improved in Self research as they were required to allow a very high level object oriented language to perform at up to half the speed of optimized C. Much of the development of Self took place at Sun Microsystems, and the techniques they developed were later deployed for Java's HotSpot virtual machine. At one point a version of Smalltalk was implemented in Self. Because it was able to use the JIT, this also gave extr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BETA (programming Language)
BETA is a pure object-oriented language originating within the "Scandinavian School" in object-orientation where the first object-oriented language Simula was developed.SourceOle Lehrmann Madsen: An overview of BETA Among its notable features, it introduced nested classes, and unified classes with procedures into so called patterns. The project is inactive as of October 2020.https://beta.cs.au.dk/ Features Technical overview From a technical perspective, BETA provides several unique features. Classes and Procedures are unified to one concept, a Pattern. Also, classes are defined as properties/attributes of objects. This means that a class cannot be instantiated without an explicit object context. A consequence of this is that BETA supports nested classes. Classes can be virtually defined, much like virtual methods can be in most object-oriented programming languages. Virtual entities (such as methods and classes) are never overwritten; instead they are redefined or specialized. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZPL (programming Language)
ZPL (short for ''Z-level Programming Language'') is an array programming language designed to replace C and C++ programming languages in engineering and scientific applications. Because its design goal was to obtain cross-platform high performance, ZPL programs run fast on both sequential and parallel computers. Highly-parallel ZPL programs are simple and easy to write because it exclusively uses implicit parallelism. Originally called Orca C, ZPL was designed and implemented during 1993–1995 by the Orca Project of the Computer Science and Engineering Department at the University of Washington. Details ZPL uses the array abstraction to implement a data parallel programming model. This is the reason why ZPL achieves such good performance: having no parallel directives or other forms of explicit parallelism, ZPL exploits the operational trait that when aggregate computations are described in terms of arrays, many scalar operations must be (implicitly) performed to implement the arr ...

High Performance Fortran
High Performance Fortran (HPF) is an extension of Fortran 90 with constructs that support parallel computing, published by the ''High Performance Fortran Forum'' (HPFF). The HPFF was convened and chaired by Ken Kennedy of Rice University. The first version of the HPF Report was published in 1993. Building on the array syntax introduced in Fortran 90, HPF uses a data parallel model of computation to support spreading the work of a single array computation over multiple processors. This allows efficient implementation on both SIMD and MIMD style architectures. HPF features included: * New Fortran statements, such as FORALL, and the ability to create PURE (side effect free) procedures * Compiler directives for recommended distributions of array data * ''Extrinsic procedure'' interface for interfacing to non-HPF parallel procedures such as those using message passing * Additional library routines - including environmental inquiry, parallel prefix/suffix (e.g., 'scan'), data scat ...

COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...
