Foreword

2005 marks t he 10^th birthday of Java technology. Starting out as just a programming language, Java technology has exploded into a ubiquitous technology platform that today touches the lives of people everywhere. The 10^th birthday celebration book tells the story of how Java technology came to influence technologists, then businesses, then consumers, and now has become the predominate software on the planet.

In the early 1990s, a small group of us from Sun Microsystems were given the opportunity to spend all of our time thinking of what "the next big thing in technology" would be. What we created was a hardware-independent software platform unlike any other. We thought it was pretty cool, and so did our developer friends. But at that time, I don't think that any of us really had any idea of what we had done, not to mention how it would change the world. I certainly know I didn't.

Of course, it wouldn't have happened if it wasn't for the Java developer community. Developers are the ones who made the technology a success over the years. Their ingenuity, creativity, and millions of hours of contributed help has made the platform what it is today. We're lucky to have millions of developers constantly driving it forward into the future.

Every day I hear about new and cool uses for Java technology. I'm gratified, and still constantly amazed.

Extend RUP to Drive Improvements Across the Entire IT Lifecycle

The Rational Unified Process is a powerful tool for improving software development -- but it doesn't go nearly far enough. Today's development organizations need to extend RUP to cover the entire IT lifecycle, including the cross-project and enterprise issues it largely ignores. The Enterprise Unified Process (EUP) does precisely that, enabling you to deliver systems that meet all the needs of today's businesses. Now, EUP's creator and architects present the definitive introduction to EUP, and demonstrate how to use it in your environment.

The Enterprise Unified Process systematically identifies the business and technical problems that RUP fails to address, and shows how EUP fills those gaps. Using actual examples and case studies, the authors introduce processes and disciplines for producing new software, implementing strategic reuse, "sunsetting" obsolete code and systems, managing software portfolios, and much more. Their independent, "tool agnostic" coverage will be indispensable no matter which RUP products or platforms you've invested in. Coverage includes

• Practical, step-by-step guidance for adopting EUP in midsized-to-large organizations

• Proven processes for optimizing ongoing IT operations and support

• Enterprise business modeling and architecture with EUP

• EUP disciplines for enterprise administration, people management, and software process improvement

• Using the new EUP plug-in for IBM's RUP platform

• Workflow diagrams fully consistent with RUP for easy understanding

• Detailed appendices covering EUP roles, artifacts, and terminology

EUP is the missing link that can help IT professionals achieve the full benefits of RUP in the enterprise. This book will help you discover it, master it, implement it, and succeed with it.

• How "data everywhere" transforms business, technology, and the way you live

• A pioneering look at grand, new efficiencies forthcoming

As communications, computing, and data storage converge, data is becoming utterly ubiquitous...and that changes everything. In this book, two leading data management visionaries reveal how data transforms the way you do business, the technologies you use, the investments you make, the life you live, and the world you live in.

Chris Stakutis and John Webster draw on interviews with nearly 50 leading experts: technologists, sociologists, entrepreneurs, consultants, researchers, media leaders, and futurists alike. You'll discover how today's "primordial soup" of wired and wireless gadgetry is quickly coalescing into something immensely more powerful, driving applications you thought were pure science fiction. You'll also gain deep insight into the profound implications of ubiquitous data capture: implications that touch everything from your bedroom to the battlefield:

• The emerging "Connectivity Divide." Which side of the chasm are you on?

• Inescapable data's technical components: Async communications,

• pervasive computing devices, wireless, and XML

• Global calendars, momentary enterprises: Transforming your life and business

• Uncontrolled information availability: Its risks to your security and well-being

• The future of technical infrastructure, grids, smart storage, and beyond

• Radical, new modes of information delivery: Nonnumeric, nontextual, unobtrusive

• Future tech: From holographic displays to fertility "wall clocks"

• Your DNA on a chip: The heart of your personal health and wellness program

"Where has this book been all my professional life? It is about time someone wrote this book. The author covers many basic, practical issues that other authors omit in a format that makes for a great troubleshooting reference and for casual perusing. There are a lot of books available that give a broad overview of system and network administration, and there are a lot of detailed books on each specific topic covered in this book, but I don't know of any other place where I can get so much useful, practical information on such a wide range of topics in such a concise and readable form. I will highly recommend it to my friends and colleagues who are trying to manage their own systems. I am anxious to show it to our instructors who teach data communications and networks as a possible text or lab manual."
