A "Hello, World!" program is generally a simple computer program which outputs to the screen a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. A "Hello, World!" program is often the first written by a student of a new programming language, but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source code is correctly installed, and that its operator understands how to use it.
KornShell (ksh) is a Unix shell which was developed by David Korn at Bell Labs in the early 1980s and announced at USENIX on July 14, 1983. The initial development was based on Bourne shell source code. Other early contributors were Bell Labs developers Mike Veach and Pat Sullivan, who wrote the Emacs and vi-style line editing modes' code, respectively. KornShell is backward-compatible with the Bourne shell and includes many features of the C shell, inspired by the requests of Bell Labs users.
The MIT License is a permissive software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts very few restrictions on reuse and therefore has high license compatibility.
The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax. Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions.
The actor model in computer science is a mathematical model of concurrent computation that treats an actor as the basic building block of concurrent computation. In response to a message it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received. Actors may modify their own private state, but can only affect each other indirectly through messaging.
IKVM.NET is an implementation of Java for Mono and the Microsoft .NET Framework. IKVM is free software, distributed under the zlib permissive free software license.
Stylometry is the application of the study of linguistic style, usually to written language. It has also been applied successfully to music, paintings, and chess.
Richard P. Gabriel is an American computer scientist known for his work in computing related to the programming language Lisp, and especially Common Lisp. His best known work was a 1990 essay "Lisp: Good News, Bad News, How to Win Big", which introduced the phrase Worse is Better, and his set of benchmarks for Lisp, termed Gabriel Benchmarks, published in 1985 as Performance and evaluation of Lisp systems. These became a standard way to benchmark Lisp implementations.
The Electronic Visualization Laboratory (EVL) is an interdisciplinary research lab and graduate studies program at the University of Illinois at Chicago, bringing together faculty, students and staff primarily from the Art and Computer Science departments of UIC. The primary areas of research are in computer graphics, visualization, virtual and augmented reality, advanced networking, and media art. Graduates of EVL either earn a Masters or Doctoral degree in Computer Science.
ISLISP is a programming language in the Lisp family standardized by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) joint working group ISO/IEC JTC 1/SC 22/WG 16. The primary output of this working group was an international standard, published by ISO. The standard was updated in 2007 and republished as ISO/IEC 13816:2007(E). Although official publication was through ISO, versions of the ISLISP language specification are available that are believed to be in the public domain.
Carole Elisabeth Chaski is a forensic linguist who is considered one of the leading experts in the field. Her research has led to improvements in the methodology and reliability of stylometric analysis and inspired further research on the use of this approach for authorship identification. Her contributions have served as expert testimony in several federal and state court cases in the United States and Canada. She is president of ALIAS Technology and executive director of the Institute for Linguistic Evidence, a non-profit research organization devoted to linguistic evidence.
Three.js is a cross-browser JavaScript library and application programming interface (API) used to create and display animated 3D computer graphics in a web browser using WebGL. The source code is hosted in a repository on GitHub.
Julia is a high-level, general-purpose dynamic programming language, most commonly used for numerical analysis and computational science. Distinctive aspects of Julia's design include a type system with parametric polymorphism and the use of multiple dispatch as a core programming paradigm, efficient garbage collection, and a just-in-time (JIT) compiler.
WebAssembly defines a portable binary-code format and a corresponding text format for executable programs as well as software interfaces for facilitating interactions between such programs and their host environment.
Code stylometry is the application of stylometry to computer code to attribute authorship to anonymous binary or source code. It often involves breaking down and examining the distinctive patterns and characteristics of the programming code and then comparing them to computer code whose authorship is known. Unlike software forensics, code stylometry attributes authorship for purposes other than intellectual property infringement, including plagiarism detection, copyright investigation, and authorship verification.
Microsoft, a technology company historically known for its opposition to the open source software paradigm, turned to embrace the approach in the 2010s. From the 1970s through 2000s under CEOs Bill Gates and Steve Ballmer, Microsoft viewed the community creation and sharing of communal code, later to be known as free and open source software, as a threat to its business, and both executives spoke negatively against it. In the 2010s, as the industry turned towards cloud, embedded, and mobile computing—technologies powered by open source advances—CEO Satya Nadella led Microsoft towards open source adoption although Microsoft's traditional Windows business continued to grow throughout this period generating revenues of 26.8 billion in the third quarter of 2018, while Microsoft's Azure cloud revenues nearly doubled.
Semgrep, Inc. is a cybersecurity company based in San Francisco. The company develops the Semgrep AppSec Platform and actively maintains the open-source static code analysis tool semgrep OSS.
AssemblyScript is a TypeScript-based programming language that is optimized for, and statically compiled to, WebAssembly. Resembling ECMAScript and JavaScript, but with static types, the language is developed by the AssemblyScript Project with contributions from the AssemblyScript community.
Adversarial stylometry is the practice of altering writing style to reduce the potential for stylometry to discover the author's identity or their characteristics. This task is also known as authorship obfuscation or authorship anonymisation. Stylometry poses a significant privacy challenge in its ability to unmask anonymous authors or to link pseudonyms to an author's other identities, which, for example, creates difficulties for whistleblowers, activists, and hoaxers and fraudsters. The privacy risk is expected to grow as machine learning techniques and text corpora develop.
