Written by the leading experts in the worldwide Squeak community, this book assembles a compelling vision of what programming can be. Squeak: Open Personal Computing and Multimedia is the only book on Squeak that addresses the advanced features for the student, researcher, multimedia developer, open source developer, hobbyist, and the professional. Developed for Smalltalk, it is for anyone that wants a powerful, cross-platform, and open alternative to the traditional multimedia and exploratory languages.FEATURES AND BENEFITS

Squeak is an open programming language designed especially for personal computing and multimedia. It's certainly the most cross-platform multimedia platform in existence. What's especially interesting is that Squeak is written almost entirely in terms of itselffor example, it is possible to extend Squeak with the speed of native processor primitives without ever writing a line of C code. This book provides a guide to some of the exciting potential of Squeak. It's not a tutorial (though there are some tutorial chapters), but instead, the book offers a path into some of Squeak's unique features:
We (the editors and authors of this book) have been living Squeak for some five years now, but for many of you, this book will be your introduction to the wonderful world of Squeak. In another sense, though, if you have used a personal computer in the last twenty years, you have already been introduced to Squeak. Squeak is quite literally the direct descendant of the original Smalltalk work through which the desktop personal computer was invented. The legendary demonstration of Smalltalk to Steve Jobs of Apple Computer by Adele Goldberg and her team at Xerox Pare in 1979 (based on which Apple developed the Lisa and then the Macintosh) was running much of the exact same code that you're running when you run Squeak.
Of course, Squeak has been advanced considerably from that base system, but mostly just in the last five years. The technical story of how Squeak came to be and how it was developed from that original Smalltalk is told in the reprinted chapter Back to the Future in this volume. The challenge posed by that story, though, is made throughout this book.
What if those who developed the desktop personal computer from the original Smalltalk work missed something? The developers of the Apple Macintosh operating system, the Microsoft Windows operating system, and all the other desktop systems didn't start from the actual work at Xerox PARC, but from impressions and demonstrations. What if the fifteen years of the development of the desktop personal computer between 1980 and the start of Squeak went down the wrong path (or at least, didn't go down the right path)?
That's the question that Squeak allows us to ask. Squeak offers us the opportunity to start at the same place as Steve Jobs and others did some twenty years ago, but to explore a different future for personal computers. The researchers at Xerox PARC are hailed for inventing and integrating the windows, icons, menus, and mouse pointer into the "WIMP" desktop user interface that we all know today, but their vision also included:
What would a personal computer be like if those ideas (and the others inherent in the vision of the Dynabook) were integrated at the heart of the desktop interface that we all use, and weren't just add-ons? This book invites you to explore the challenge of an alternate future for personal computers. The chapters of this volume were selected not only to serve as a tutorial and invitation to explore Squeak, but also to pose challenges, opportunities, and intriguing glimpses into a future of personal computing different from that posed by existing systems. Please do accept the challenge, see what Apple and Microsoft saw at the dawn of personal computing, and see what future you and your own vision can make for personal computing.
