Fabrik is a visual programming environment - a kit of computational and user-interface components that can be “wired” together to build new components and useful applications. Fabrik diagrams utilize bidirectional dataflow connections as a shorthand for multiple paths of flow. Built on object-oriented foundations. Fabrik components can compute(More)
The purpose of the Smalltalk project is to provide computer support for the creative spirit in everyone. Our work flows from a vision that includes a creative individual and the best computing hardware available. We have chosen to concentrate on two principle areas of research: a language of description (programming language) that serves as an interface(More)
This paper describes a programming system based on the metaphor of communicating objects. Experience with a running system shows that this model provides flexibility, modularity and compactness. A compiled representation for the language is presented, along with an interpreter suitable for microcoding. The object-oriented model provides naturally efficient(More)
For better or worse, the web browser has become a widely used target platform for software applications. Desktop-style applications such as word processors, spreadsheets, calendars, games and instant messaging systems that were earlier written for specific operating systems, CPU architectures or devices are now written for the World Wide Web, to be used(More)
