Squeak

Draft

Definition

• Squeak is highly portable open-source Smalltalk with powerful multimedia facilities. Squeak is used for a wide variety of computing tasks, ranging from child education to innovative research in computer science, or creation of advanced dynamic web sites.

• In education, Squeak often just refers to Squeak Etoys, an easy visual programming language/ execution environment built on top of Squeak that is a very popular tool for building microworlds (designers, teachers and children as authors).

• “Squeak Etoys was inspired by LOGO, PARC-Smalltalk, Hypercard, and starLOGO. It is a media-rich authoring environment with a simple powerful scripted object model for many kinds of objects created by end-users that runs on many platform, and is free and open source. It includes 2D and 3D graphics, images, text, particles, pres-entations, web-pages, videos, sound and MIDI, etc. It includes the ability to share desktops with other Etoy users in real-time, so many forms of immersive mentoring and play can be done over the Internet” (Etoys and learning)

• The best known member of the squeak community is probably Alan Kay, inventor of the Dynabook and who is also known by: The best way to predict the future is to invent it.

Note: Maybe we should separate Etoys from Squeak and make two articles. Etoys has gained recent interest again, because it ships with the OLPC (the 100$ PC).

Squeak in education

• Squeakland is the home for Etoy, an easy graphical programming environment built on top of Squeak. This site has downloads, information for teachers and children, papers, etc.

• Scratch is a programming language for children animations, games, and interactive art. Developped at MIT's LifeLong Kindergarten group.

• ComiKit is a Swedish product for making games and interactive pictures.

• The Swiki server is a very popular Wiki System (despite the fact that development seems to be frozen). E.g. TECFA runs 2 Swiki servers that are used in the school system.

• Squeak is also a important foundation of [Croquet], an open source software platform for creating deeply collaborative multi-user online applications
