"His book is very compatible with XP. It is not about drawing pictures of a domain; it is about how you think of it, the language you use to talk about it, and how you organize your software to reflect your improving understanding of it. Eric thinks that learning about your problem domain is as likely to happen at the end of your project as at the beginning, and so refactoring is a big part of his technique. "The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers--it is a future classic." --Ralph Johnson, author of Design Patterns "If you don't think you are getting value from your investment in object-oriented programming, this book will tell you what you've forgotten to do. "Eric Evans convincingly argues for the importance of domain modeling as the central focus of development and provides a solid framework and set of techniques for accomplishing it. This is timeless wisdom, and will hold up long after the methodologies du jour have gone out of fashion." --Dave Collins, author of Designing Object-Oriented User Interfaces "Eric weaves real-world experience modeling--and building--business applications into a practical, useful book. Written from the perspective of a trusted practitioner, Eric's descriptions of ubiquitous language, the benefits of sharing models with users, object life-cycle management, logical and physical application structuring, and the process and results of deep refactoring are major contributions to our field." --Luke Hohmann, author of Beyond Software Architecture "This book belongs on the shelf of every thoughtful software developer." --Kent Beck "What Eric has managed to capture is a part of the design process that experienced object designers have always used, but that we have been singularly unsuccessful as a group in conveying to the rest of the industry. We've given away bits and pieces of this knowledge...but we've never organized and systematized the principles of building domain logic. This book is important." --Kyle Brown, author of Enterprise Java(TM) Programming with IBM(R) WebSphere(R) The software development community widely acknowledges that domain modeling is central to software design. Through domain models, software developers are able to express rich functionality and translate it into a software implementation that truly serves the needs of its users. But despite its obvious importance, there are few practical resources that explain how to incorporate effective domain modeling into the software development process. Domain-Driven Design fills that need. This is not a book about specific technologies. It offers readers a systematic approach to domain-driven design, presenting an extensive set of design best practices, experience-based techniques, and fundamental principles that facilitate the development of software projects facing complex domains. Intertwining design and development practice, this book incorporates numerous examples based on actual projects to illustrate the application of domain-driven design to real-world software development. Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team. A shift in emphasis--refactoring not just the code but the model underlying the code--in combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer. Domain-Driven Design then builds on this foundation, and addresses modeling and design for complex systems and larger organizations.Specific topics covered include:Getting all team members to speak the same language Connecting model and implementation more deeply Sharpening key distinctions in a model Managing the lifecycle of a domain object Writing domain code that is safe to combine in elaborate ways Making complex code obvious and predictable Formulating a domain vision statement Distilling the core of a complex domain Digging out implicit concepts needed in the model Applying analysis patterns Relating design patterns to the model Maintaining model integrity in a large system Dealing with coexisting models on the same project Organizing systems with large-scale structures Recognizing and responding to modeling breakthroughs With this book in hand, object-oriented developers, system analysts, and designers will have the guidance they need to organize and focus their work, create rich and useful domain models, and leverage those models into quality, long-lasting software implementations.

    A young page in Queen Elizabeth and Prince Philip’s wedding, in thirty short years William became the House of Windsor's first modern prince but has been largely forgotten. He tested the limits of royal convention in work and love by pursuing a career in business and diplomacy and dating women who could never be accepted as a royal bride. William also lived an adventurous life, escaping several near death experiences during travels around the world, witnessing one of the most tragic periods in American history, and becoming a competitive pilot before his life was cut short in a tragic accident.Based on personal accounts by the family and friends who knew William best, extracts from his own reflections on his life and family, and photographs at different stages of his life, this book provides a unique glimpse into a prince’s coming of age and what growing up in the British royal family is really like.

    It’s nearly impossible because without the right connections, a good early education, and financial wealth to back you up, you might as well sit on the sidelines and fold your arms. When you have nothing going for you, and/or obligations to tend to, shackling you to the ground (money doesn’t grow on trees), you might not even see the point in starting, because creating a life of dreams must surely be for the 1%. If you think creating a more desired life is costly, you are right - it’s not easy. It requires dedication and a willingness to give up short-term satisfaction, and that means being prepared to give some of your happiness away for the greater, long-term good. However, if that all sounds a bit too much – why would you want to sacrifice your happiness? – then you need to take a step back and foresee a different kind of outcome that will inevitably unfold if you take the "road most taken": a future of unrealized potential; an underlying, constant inner-discomfort; and, the most horrid of all, regret. And what is the "road most taken"? It’s the easy road out. It’s the road most people take in life, the one that appears comfortable and easy, but is actually laden with nightmares and discomfort. If you’re ignoring your dreams to pursue something more acceptable or less risky, you are taking the road most taken.Fortunately, there are things that you can do in life that will immediately snap you back to what is important: you and your magnificent potential. What is perhaps the most powerful tool of all that will help you get back on track? It’s learning from people who have gone beyond what is humanly thought possible, like Albert Einstein, a man who once thought he was worthless (who wrote a letter to his parents telling them that he should never have been born, because he was useless), but who ended up being a legend among people, an inspiration who unlocked the very secrets of life. There is so much love, power, and potential in you, and you don’t even realize it. However, you can bring these things out in yourself by studying the great. When you study great leaders, like Albert Einstein, you are essentially absorbing their wisdom, something that will radically change your life not years from now, but now, the moment you start reading the coming chapters. What follows are the greatest life lessons from Albert Einstein, wisdom that can easily be applied to your own life. They were carefully selected and dissected in meaning to help you gain the most out of them. There is a powerful reason why Albert Einstein was so great: he was human, and he realized it.Scroll up and grab your copy today.

    This groundbreaking new book sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers, and operations, delivery teams can get changes released in a matter of hours-- sometimes even minutes-no matter what the size of a project or the complexity of its code base. Jez Humble and David Farley begin by presenting the foundations of a rapid, reliable, low-risk delivery process. Next, they introduce the "deployment pipeline," an automated process for managing all changes, from check-in to release. Finally, they discuss the "ecosystem" needed to support continuous delivery, from infrastructure, data and configuration management to governance. The authors introduce state-of-the-art techniques, including automated infrastructure management and data migration, and the use of virtualization. For each, they review key issues, identify best practices, and demonstrate how to mitigate risks. Coverage includes - Automating all facets of building, integrating, testing, and deploying software - Implementing deployment pipelines at team and organizational levels - Improving collaboration between developers, testers, and operations - Developing features incrementally on large and distributed teams - Implementing an effective configuration management strategy - Automating acceptance testing, from analysis to implementation - Testing capacity and other non-functional requirements - Implementing continuous deployment and zero-downtime releases - Managing infrastructure, data, components and dependencies - Navigating risk management, compliance, and auditing Whether you're a developer, systems administrator, tester, or manager, this book will help your organization move from idea to release faster than ever--so you can deliver value to your business rapidly and reliably.
