ObjectStudio® - an object-oriented development environment that enables large organizations to quickly design, assemble, and maintain complex component-based applications. ObjectStudio is unique in providing integrated object modeling (visually defined objects) and object mapping (visually linked objects), within a single development environment.

VisualWorks® - a robust Smalltalk development environment that provides cross-platform compatibility across Windows, Macintosh and a variety of Unix platforms (including Linux). Additionally, VisualWorks offers strong integration with the Internet, and a core engine that is widely recognized as the best performing and most stable in the Smalltalk market.

Please review our OOPLSA 1999 Trip Report on "Fun with Squeak and other Smalltalks" Other interesting information can be found in the Camp Smalltalk Stories

"Squeak is an open, highly-portable Smalltalk-80 implementation whose virtual machine is written entirely in Smalltalk, making it easy to debug, analyze, and change. To achieve practical performance, a translator produces an equivalent C program whose performance is comparable to commercial Smalltalks.

How is Squeak important? Squeak extends the fundamental Smalltalk philosophy of complete openness -- where everything is available to see, understand, modify, and extend for whatever purpose -- to include even the VM. It is a genuine, complete, compact, efficient Smalltalk-80 environment (*not* a toy). It is not specialized for any particular hardware/OS platform. Porting is easy -- you are not fighting entrenched platform/OS dependencies to move to a new system or configuration. It has essentially been put into the public domain - greatly broadening potential interest, and potential applications. The core team behind Squeak includes Dan Ingalls, Alan Kay, Ted Kaehler, John Maloney, and Scott Wallace. All of this has attracted many of the best and most experienced Smalltalk programmers and implementers in the world."

The "Best" set of documentation for Squeak can be found at Andrew C. Greenberg's site. In fact it's the best set of documentation on Smalltalk I've ever seen!

Smalltalk/X (ST/X) is a complete implementation of the Smalltalk programming language and development environment providing:

• Object Oriented Programming Language
• Graphical Development Environment with Editors, Browsers, etc.
• Incremental Compiler and byte code interpreter.
• Extensive Class Library with ready-to-use building blocks for Applications
• Symbolic Debugger

The implementation of the language and the class library is consistent with the draft ANSI standard as well as the industry standard.

Note that on Nov 1st 2001 the license changed:

Welcome to Smalltalk/X (ST/X) version 4.1.2.

Most important first: we have changed our licencing policy; ST/X may now be used - even commercially - without any license fee. This shall help to spread the Smalltalk language and strengthen the Smalltalk comunity.

IBM VisualAge Smalltalk Enterprise V6 enables you to quickly build world-class e-business applications that help you hit it big with your customers and beat your competition.

"Over the years I have been asked by countless clients, "Why should we use Smalltalk." The goal of this website is to help answer this very complex question. "

*note in Oct 1999 Mr. McIntosh was awarded the "consultant of the month" honor by this website.

"DIGITALIS is the name of a spare time project of mine - Torsten Bergmann (also known as Cronos). I'm a student of computer science at the Technical University of Ilmenau and work as developer and consultant for the Phaidros Software AG. I started Digitalis in 1996 to provide informations about my favourite programming language Smalltalk. I first wanted to write a book about VisualWorks in german, because most books about Smalltalk are written in english. But it was hard to see that the Smalltalk market is not static and informations are often not 'state of the art'. Nothing is so dynamic like the internet - so I decided to put the texts on the net. The second reason for doing this was the lack of time - I hoped that there is someone out there who want's to help me. "

"The STIC web exists to promote the Smalltalk language, providing a high-quality, centralized repository of Smalltalk industry information. This site consolidates Internet-available information and publishes additional STIC-funded research and data."

In early 2002 it was pointed out to me that this link no longer works. Why? Go see the notes on the STIC Smalltalk Industry council Meeting at OOPSLA found at my OOPSLA 2000 Trip Report. Will it come back someday, well try the link again today!

This is a really cool page since it allows you to add links!

This site has a very large collection of links to Smalltalk, Object Technology and other languages.
