Smalltalk is a purely object oriented programming language (OOP) that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learning Research Group (LRG) scientists, including Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Diana Merry, and Scott Wallace.
Model–view–controller (MVC) is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected elements. These elements are:
Amber is a fossilized tree resin.
In object-oriented programming, a metaclass is a class whose instances are classes themselves. Unlike ordinary classes, which define the behaviors of objects, metaclasses specify the behaviors of classes and their instances. Not all object-oriented programming languages support the concept of metaclasses. For those that do, the extent of control metaclasses have over class behaviors varies. Metaclasses are often implemented by treating classes as first-class citizens, making a metaclass an object that creates and manages these classes. Each programming language adheres to its own metaobject protocol, which are the rules that determine interactions among objects, classes, and metaclasses. Metaclasses are utilized to automate code generation and to enhance framework development.
Small talk is an informal type of conversation.
Daniel Henry Holmes Ingalls Jr. is a pioneer of object-oriented computer programming and the principal architect, designer and implementer of five generations of Smalltalk environments. He designed the bytecoded virtual machine that made Smalltalk practical in 1976. He also invented bit blit, the general-purpose graphical operation that underlies most bitmap computer graphics systems today, and pop-up menus. He designed the generalizations of BitBlt to arbitrary color depth, with built-in scaling, rotation, and anti-aliasing. He made major contributions to the Squeak version of Smalltalk, including the original concept of a Smalltalk written in itself and made portable and efficient by a Smalltalk-to-C translator.
A plan is a set of instructions for attaining a given objective.
Glass is an amorphous material commonly used in windows, tableware, optoelectronics, and decorative items.
Programming languages are used for controlling the behavior of a machine. Like natural languages, programming languages follow rules for syntax and semantics.
Chaos or CHAOS may refer to:
In computer programming, a programming language implementation is a system for executing computer programs. There are two general approaches to programming language implementation:
Flavour or flavor is either the sensory perception of taste or smell, or a flavoring in food that produces such perception.
Apple Dylan is the original implementation of the programming language Dylan. It was developed by Apple Computer from 1992 to 1995.
GemStone/S is computer software, an application framework that was first available for the programming language Smalltalk as an object database. It is proprietary commercial software.
Pharo is a cross-platform implementation of the classic Smalltalk-80 programming language and runtime system. It is based on the OpenSmalltalk virtual machine (VM) named Cog, which evaluates a dynamic, reflective, and object-oriented programming language with a syntax closely resembling Smalltalk-80. It is free and open-source software, released under a mix of MIT, and Apache 2 licenses.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which can contain data and code: data in the form of fields, and code in the form of procedures. In OOP, computer programs are designed by making them out of objects that interact with one another.
GNU Dr. Geo is an interactive geometry software that allows its users to design & manipulate interactive geometric sketches, including dynamic models of Physics. It is free software, created by Hilaire Fernandes, it is part of the GNU project. It runs over a Morphic graphic system. Dr. Geo was initially developed in C++ with Scheme scripting, then in various versions of Smalltalk with Squeak, Etoys_(programming_language) for One Laptop per Child Pharo then Cuis-Smalltalk.
MagLev is an alternative implementation of the Ruby programming language built on the GemStone/S virtual machine from GemTalk Systems. Much of Maglev was set out to be written in Ruby as much as possible, resulting in some collaboration with the Rubinius project. As of the first beta release, the project runs RubyGems 1.3.5 natively, with support for C and Smalltalk extensions. MagLev has a distinct VM architecture that allows it to share code and data between runtimes and execution cycles through a Ruby API.
