´´Eric Evans has written a fantastic book on how you can make the design of your software match your mental model of the problem domain you are addressing. ´´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® WebSphere® 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 (DDD) software modeling delivers powerful results in practice, not just in theory, which is why developers worldwide are rapidly moving to adopt it. Now, for the first time, there´s an accessible guide to the basics of DDD: What it is, what problems it solves, how it works, and how to quickly gain value from it. Concise, readable, and actionable, Domain-Driven Design Distilled never buries you in detail-it focuses on what you need to know to get results. Vaughn Vernon, author of the best-selling Implementing Domain-Driven Design, draws on his twenty years of experience applying DDD principles to real-world situations. He is uniquely well-qualified to demystify its complexities, illuminate its subtleties, and help you solve the problems you might encounter. Vernon guides you through each core DDD technique for building better software. You´ll learn how to segregate domain models using the powerful Bounded Contexts pattern, to develop a Ubiquitous Language within an explicitly bounded context, and to help domain experts and developers work together to create that language. Vernon shows how to use Subdomains to handle legacy systems and to integrate multiple Bounded Contexts to define both team relationships and technical mechanisms. Domain-Driven Design Distilled brings DDD to life.
HIGHLIGHT A Domain Specific Language lets you express the intent of a piece of code in more human-readable terms. Boo is an ideal language to create DSLs for .NET. DESCRIPTION Even good code can be tough to understand when you simply read it-even if you´re a developer and you know what it does! A Domain Specific Language (DSL) helps a developer clearly express the intent of the code, and thus make it easier to work on the core business problem. Developers who migrate to Ruby from Java love Boo´s ability to define a DSL for .NET in a just few lines of code. In Boo, the developer can define simple DSLs for .NET applications without suffering through the awkward XML usually required. Building Domain Specific Languages in Boo shows how to write DSLs for .NET. It starts by teaching what a DSL is. Then, it provides a fast-paced Boo tutorial. Readers immediately start putting this handy language to productive use as they learn how to implement DSLs in real code. The author shows how to create several types of DSLs, all with the goal of making the developer more productive. Along the way, readers learn the Boo they need techniques to scare away the evil XML. KEY POINTS . Author Ayende Rahien is world-famous as a speaker and blogger on this topic . This book covers both the theory and the practice of building DSLs . This is the only book available that teaches Boo MARKET INFORMATION Anything that makes coding faster and better is of interest to developers. Writing DSLs has the potential to improve both speed of development and quality of code! This approach is unique, in that it brings a common technique for Ruby and Java developers to the .NET platform.
The world is dead, devoured by a plague of reanimated corpses. In a crumbling city, Sarah, Nathan, and a band of survivors barricade themselves inside a warehouse surrounded by a sea of shambling putrefaction. Days in seclusion blur by, and their food is nearly gone. The group is faced with two possible deaths: creeping starvation, or the undead outside the warehouse. As Sarah stands on the edge of the warehouse roof preparing to step out into oblivion she spots a glimmer of hope. In the distance a helicopter approaches the city... but is it the salvation the survivors have been waiting for? And do they dare attempt to fight their way through the mass of infected dead to reach it? BONUS AUDIO: Includes an exclusive introduction by the author. 1. Language: English.

An urgent new warning from two bestselling security experts--and a gripping inside look at how governments, firms, and ordinary citizens can confront and contain the tyrants, hackers, and criminals bent on turning the digital realm into a war zone. ´´In the battle raging between offense and defense in cyberspace, Clarke and Knake have some important ideas about how we can avoid cyberwar for our country, prevent cybercrime against our companies, and in doing so, reduce resentment, division, and instability at home and abroad.´´--Bill Clinton There is much to fear in the dark corners of cyberspace. From well-covered stories like the Stuxnet attack which helped slow Iran´s nuclear program, to lesser-known tales like EternalBlue, the 2017 cyber battle that closed hospitals in Britain and froze shipping crates in Germany in midair, we have entered an age in which online threats carry real-world consequences. But we do not have to let autocrats and criminals run amok in the digital realm. We now know a great deal about how to make cyberspace far less dangerous--and about how to defend our security, economy, democracy, and privacy from cyber attack. This is a book about the realm in which nobody should ever want to fight a war: the fifth domain, the Pentagon´s term for cyberspace. Our guides are two of America´s top cybersecurity experts, seasoned practitioners who are as familiar with the White House Situation Room as they are with Fortune 500 boardrooms. Richard A. Clarke and Robert K. Knake offer a vivid, engrossing tour of the often unfamiliar terrain of cyberspace, introducing us to the scientists, executives, and public servants who have learned through hard experience how government agencies and private firms can fend off cyber threats. Clarke and Knake take us inside quantum-computing labs racing to develop cyber superweapons; bring us into the boardrooms of the many firms that have been hacked and the few that have ¬ and walk us through the corridors of the U.S. intelligence community with officials working to defend America´s elections from foreign malice. With a focus on solutions over scaremongering, they make a compelling case for ´´cyber resilience´´--building systems that can resist most attacks, raising the costs on cyber criminals and the autocrats who often lurk behind them, and avoiding the trap of overreaction to digital attacks. Above all, Clarke and Knake show us how to keep the fifth domain a humming engine of economic growth and human progress by not giving in to those who would turn it into a wasteland of conflict. Backed by decades of high-level experience in the White House and the private sector, The Fifth Domain delivers a riveting, agenda-setting insider look at what works in the struggle to avoid cyberwar.
