Squeak 4.2 Released

Squeak 4.2 has been released after nine months in development. 4.2 is cleaner and faster than 4.1, with a significant number of fixes and enhancements to the class-library, such as an API for accessing the operating system stdio. There were low-level core improvements too, such as the new microsecond-precision internal clock and legacy MVC support. IDE productivity is higher with the text-editor enhancements, and a new gesture for efficiently resizing and moving windows. Squeak 4.2 is compatible with the next-generation Cog VM.

Cog, a Squeak JIT VM with 2x-10x Speedup Released

Eliot Miranda announced that Teleplace released under a MIT license his work on a long awaited and anticipated new JIT virtual engine for Squeak and friends called Cog, with 2x-10x improvement in performance.  It is available on our ftp site.

Squeak

Welcome to the World of Squeak!

Squeak is a modern, open source, full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change. Squeak is the vehicle for a wide range of projects from multimedia applications, educational platforms to commercial web application development.

Extraordinary Squeak

Noteworthy uses of Squeak

• Children's Machine - The One Laptop Per Child (OLPC) initiative leverages Squeak to power the Etoys application shipped with every laptop around the world.

• Etoys is a powerful script-based environment to learn science and math by encouraging exploration and experimentation.

• Pharo is a Squeak fork that focuses on web application development. The Seaside development team does its development work on Pharo. 

• Seaside and Aida/Web are two web frameworks for developing complex dynamic web applications which by leveraging the Smalltalk strengths considerably ease the web application development.

• Croquet is an open source software platform for creating deeply collaborative 3D multi-user online applications. It features a network architecture that supports communication, collaboration, resource sharing, and synchronous computation among multiple users.

• Sophie is a digital media assembly tool to combine images, text, video, and audio into a single multimedia document such as slideshows, presentations and annotated videos.

• Scratch is a new programmable toolkit that enables kids to create their own games, animated stories, and interactive art -- and share their creations with one another over the Net. Scratch builds on the tradition of Logo and LEGO/Logo, but takes advantage of new computational ideas to make it easier to get started with programming (lowering the floor) and extend the range of what kids can create and learn (raising the ceiling).
