The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

    This book draws on material Michael created for his renowned Object Mentor seminars, techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include: Understanding the mechanics of software change, adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform, with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren't object-oriented Handling applications that don't seem to have any structureThis book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes.

    This book contains the fundamental laws of software development, the primary pieces of understanding that make the difference between a mid-level/junior programmer and the high-level senior software engineer. The book exists to help all programmers understand the process of writing software, on a very fundamental level that can be applied to any programming language or project, from here into eternity. Code Simplicity is also written in such a way that even non-technical managers of software teams can gain an understanding of what the “right way” and the “wrong way” is (and why they are right and wrong) when it comes to software design. The focus of the book is primarily on “software design,” the process of creating a plan for a software project and making technical decisions about the pattern and structure of a system.

    My name's Frank Chimero. I've spent the better part of the last two years writing and speaking on design and thinking about the topics that orbit the practice: storytelling, concept, craft, and improvisation. I want to take all of the ideas I've had and connected these past few months and capture them in a book format.I've been teaching for the past 5 years, and I've always been a bit frustrated that there isn't a nice, concise book that overviews the mental state of a successful designer while they go through their creative process. For instance, many say that graphic design is visual communication. A cornerstone of communication is storytelling, and yet you'd be hard-pressed to find any discussion of how to tell stories with design in any design book. This should be remedied.There are new challenges in the world that need to be discussed, and I think design is a prime lens to consider these topics. As our world moves faster and as things become less stable, it becomes more important for individuals to embrace ambiguity, understand paradox, and realize that two things can conflict and still somehow both be true. We must realize that logic doesn't always work, and that sometimes nonsense is the best answer. These are the topics I intend to address in the book.The Shape of Design isn't going to be a text book. The project will be focused on Why instead of How. We have enough How; it's time for a thoughtful analysis of our practice and its characteristics so we can better practice our craft. After reading the book, I want you to look at what you do in a whole new light. Design is more than working for clients.But really, this book aims to look at the mindset and worldview that designing develops in order to answer one big, important question: How can we make things that help all of us live better?"

    Yesterday's web design deliverables fail to take into account the demands of responsive solutions. Design workflow hasn't really changed, but best practices have.

    Prototypes help you to flesh out design ideas, test assumptions, and gather real-time feedback from users. With this book, Todd Zaki Warfel shows how prototypes are more than just a design tool by demonstrating how they can help you market a product, gain internal buy-in, and test feasibility with your development team. TESTIMONIALS "When someone asks me about prototyping, I'll be pointing them to this book from now on." â��Kim Goodwin: VP Design, Cooper; author, Designing for the Digital Age "Todd's text offers a comprehensive view of prototyping--from the role of prototypes in socializing decision making and achieving organizational buy-in, to the actual pragmatics of creating interactive artifacts. This is a solid book for those 'in the trenches'--the designers doing the actual work that ends up in the actual products we use every day." â��Jon Kolko: Editor-in-Chief, interactions; Associate Creative Director, Frog "If you design applications and are stuck in the land of task flows and wireframes, you really need to pick up a copy of Prototyping: A Practitioner's Guide. Todd offers practical, hands-on advice to jump start your prototyping and make your designs truly interactive before they are built." â��Dan Saffer: Principal, Kicker Studios; author of Designing for Interaction and Designing Gestural Interfaces "Whether you're prototyping to explore ideas or to communicate them, Todd Zaki Warfel's smart, accessible guide will give you the tools you need." â��Jesse James Garrett: Author, The Elements of User Experience; President, Adaptive Path

    The authors also include examples covering a variety of different integration technologies, such as JMS, MSMQ, TIBCO ActiveEnterprise, Microsoft BizTalk, SOAP, and XSL.

The authors present practical advice on designing code that connects an application to a messaging system, and provide extensive information to help you determine when to send a message, how to route it to the proper destination, and how to monitor the health of a messaging system. If you want to know how to manage, monitor, and maintain a messaging system once it is in use, get this book.

    In user experience, stories help us to understand our users, learn about their goals, explain our research, and demonstrate our design ideas. In this book, Quesenbery and Brooks teach you how to craft and tell your own unique stories to improve your designs.

    What type of font to use? How big? How should those letters, words, and paragraphs be aligned, spaced, ordered, shaped, and otherwise manipulated? In this groundbreaking new primer, leading design educator and historian Ellen Lupton provides clear and concise guidance for anyone learning or brushing up on their typographic skills. Thinking with Type is divided into three sections: letter, text, and grid. Each section begins with an easy-to-grasp essay that reviews historical, technological, and theoretical concepts, and is then followed by a set of practical exercises that bring the material covered to life. Sections conclude with examples of work by leading practitioners that demonstrate creative possibilities (along with some classic no-no's to avoid).

    In User Stories Applied, Mike Cohn provides you with a front-to-back blueprint for writing these user stories and weaving them into your development lifecycle.You'll learn what makes a great user story, and what makes a bad one. You'll discover practical ways to gather user stories, even when you can't speak with your users. Then, once you've compiled your user stories, Cohn shows how to organize them, prioritize them, and use them for planning, management, and testing.User role modeling: understanding what users have in common, and where they differ Gathering stories: user interviewing, questionnaires, observation, and workshops Working with managers, trainers, salespeople and other proxies Writing user stories for acceptance testing Using stories to prioritize, set schedules, and estimate release costs Includes end-of-chapter practice questions and exercises User Stories Applied will be invaluable to every software developer, tester, analyst, and manager working with any agile method: XP, Scrum... or even your own home-grown approach.
