Ralph Johnson (computer Scientist)
Ralph E. Johnson is a Research Associate Professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign. He is a co-author of the influential computer science textbook '' Design Patterns: Elements of Reusable Object-Oriented Software'', for which he won the 2010 ACM SIGSOFT Outstanding Research Award. In 2006 he was awarded the Dahl–Nygaard Prize for his contributions to the state of the art embodied in that book as well. Johnson was an early pioneer in the Smalltalk community and is a continued supporter of the language. He has held several executive roles at the ACM Object-Oriented Programming, Systems, Languages and Applications conference OOPSLA. He initiated the popular OOPSLA Design Fest workshop.

Design Patterns
''Design Patterns: Elements of Reusable Object-Oriented Software'' (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch. The book is divided into two parts, with the first two chapters exploring the capabilities and pitfalls of object-oriented programming, and the remaining chapters describing 23 classic software design patterns. The book includes examples in C++ and Smalltalk. It has been influential to the field of software engineering and is regarded as an important source for object-oriented design theory and practice. More than 500,000 copies have been sold in English and in 13 other languages. The authors are often referred to as the Gang of Four (GoF). History The book started at a birds of a feather (BoF) session at OOPSLA '90, "Towards an Architecture Handbook", run by Bruce Anderson, where Erich Gamma and Richard Helm met and d ...

JUnit
JUnit is a unit testing framework for the Java programming language. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks which is collectively known as xUnit that originated with SUnit. JUnit is linked as a JAR at compile-time. The latest version of the framework, JUnit 5, resides under package org.junit.jupiter. Previous versions JUnit 4 and JUnit 3 were under packages org.junit and junit.framework, respectively. A research survey performed in 2013 across 10,000 Java projects hosted on GitHub found that JUnit (in a tie with slf4j-api) was the most commonly included external library. Each library was used by 30.7% of projects. Example of a JUnit test fixture A JUnit test fixture is a Java object. Test methods must be annotated by the @Test annotation. If the situation requires it, it is also possible to define a method to execute before (or after) each (or all) of the test methods with the @BeforeEach (or @ ...

Eclipse (software)
Eclipse is an integrated development environment (IDE) used in computer programming. It contains a base workspace and an extensible plug-in (computing), plug-in system for customizing the environment. It is the second-most-popular IDE for Java (programming language), Java development, and, until 2016, was the most popular. Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including Ada (programming language), Ada, ABAP, C (programming language), C, C++, C Sharp (programming language), C#, Clojure, COBOL, D (programming language), D, Erlang (programming language), Erlang, Fortran, Groovy (programming language), Groovy, Haskell (programming language), Haskell, JavaScript, Julia (programming language), Julia, Lasso (programming language), Lasso, Lua (programming language), Lua, Software AG, NATURAL, Perl, PHP, Prolog, Python (programming language), Py ...

Visual Studio Code
Visual Studio Code, also commonly referred to as VS Code, is a source-code editor made by Microsoft with the Electron Framework, for Windows, Linux and macOS. Features include support for debugging, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git. Users can change the theme, keyboard shortcuts, preferences, and install extensions that add additional functionality. In the Stack Overflow 2021 Developer Survey, Visual Studio Code was ranked the most popular developer environment tool among 82,000 respondents, with 70% reporting that they use it. History Visual Studio Code was first announced on April 29, 2015, by Microsoft at the 2015 Build conference. A preview build was released shortly thereafter. On November 18, 2015, the source of Visual Studio Code was released under the MIT License, and made available on GitHub. Extension support was also announced. On April 14, 2016, Visual Studio Code graduated from the public preview ...

Dahl–Nygaard Prize
The Dahl–Nygaard Prize is awarded annually to a senior researcher with outstanding career contributions and a younger researcher who has demonstrated great potential. The senior prize is recognized as one of the most prestigious prizes in the area of software engineering, though it is a relatively new prize. The winners of both awards are announced at the European Conference on Object Oriented Programming (ECOOP). The prizes are named after Ole-Johan Dahl and Kristen Nygaard, two Norwegian pioneers in the area of programming and simulation. The prize was created by the Association Internationale pour les Technologies Objets (AITO) in 2004. The recipients of the prize are: * 2022, Berlin: Dan Ingalls (senior prize) and Magnus Madsen (junior prize) * 2021, Aarhus: Kim Bruce (senior prize) and Karim Ali (junior prize) * 2020, Berlin: Jan Vitek (senior prize) and Jonathan Bell (junior prize) * 2019, London: Laurie Hendren (senior prize) and Ilya Sergey (junior prize) * 2018, Amste ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

OOPSLA
OOPSLA (Object-Oriented Programming, Systems, Languages & Applications) is an annual ACM research conference. OOPSLA mainly takes place in the United States, while the sister conference of OOPSLA, ECOOP, is typically held in Europe. It is operated by the Special Interest Group for Programming Languages (SIGPLAN) group of the Association for Computing Machinery (ACM). OOPSLA is an annual conference covering topics related to object-oriented programming systems, languages and applications. Like other conferences, OOPSLA offers various tracks and many simultaneous sessions, and thus has a different meaning to different people. It is an academic conference, and draws doctoral students who present peer-reviewed papers. It also draws a number of non-academic attendees, many of whom present experience reports and conduct panels, workshops and tutorials. OOPSLA has been instrumental in helping object-oriented programming develop into a mainstream programming paradigm. It has also helpe ...
