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

    We need to go beyond 'going green' and to enlist a new generation of design activists, she wrote in an influential manifesto. We need big hearts, bigger business sense and the bravery to take action now.Featuring more than 100 contemporary design products and systems--safer baby bottles, a high-tech waterless washing machine, low-cost prosthetics for landmine victims, Braille-based Lego-style building blocks for blind children, wheelchairs for rugged conditions, sugarcane charcoal, universal composting systems, DIY soccer balls--that are as fascinating as they are revolutionary, this exceptionally smart, friendly and well-designed volume makes the case for design as a tool to solve some of the world's biggest social problems in beautiful, sustainable and engaging ways--for global citizens in the developing world and in more developed economies alike. Particularly at a time when the weight of climate change, global poverty and population growth are impossible to ignore, Pilloton challenges designers to be changemakers instead of stuff creators. Urgent and optimistic, a compendium and a call to action, Design Revolution is easily the most exciting design publication to come out this year.Emily Pilloton is the founder and Executive Director of Project H Design, a global industrial design nonprofit with eight chapters around the world. Trained in architecture at the University of California, Berkeley, and product design at the School of the Art Institute of Chicago, Pilloton started Project H in 2008 to provide a conduit and catalyst for need-based product design that empowers individuals, communities and economies. Current Project H initiatives include water transport and filtration systems in South Africa and India; an educational math playground built for elementary schools in Uganda and North Carolina; a homeless-run design coop in Los Angeles; and design concepts for foster care education and therapy in Austin, Texas.Allan Chochinov is Editor in Chief of Core77.com, and writes and lectures widely on the impact of design on contemporary culture.

    Scott doesn’t just show you which sliders do what (every Lightroom book will do that). Instead, by using the following three simple, yet brilliant, techniques that make it just an incredible learning tool, this book shows you how to create your own photography workflow using Lightroom: Throughout the book, Scott shares his own personal settings and studiotested techniques. Each year he trains thousands of Lightroom users at his live seminars and through that he’s learned what really works, what doesn’t, and he tells you flat out which techniques work best, which to avoid, and why. The entire book is laid out in a real workflow order with everything step by step, so you can begin using Lightroom like a pro from the start. What really sets this book apart is the last chapter. This is where Scott dramatically answers his #1 most-asked Lightroom question, which is: “Exactly what order am I supposed to do things in, and where does Photoshop fit in?” You’ll see Scott’s entire start-to-finish Lightroom 5 workflow and learn how to incorporate it into your own workflow. Plus, this book includes a downloadable collection of some of the hottest Lightroom Develop module presets to give you a bunch of amazing effects with just one click! Scott knows first-hand the challenges today’s digital photographers are facing, and what they want to learn next to make their workflow faster, easier, and more fun. He has incorporated all of that into this major update for Lightroom 5. It’s the first and only book to bring the whole process together in such a clear, concise, and visual way. Plus, the book includes a special chapter on integrating Adobe Photoshop seamlessly right into your workflow, and you’ll also learn some of Scott’s latest Photoshop portrait retouching techniques and special effects, which take this book to a whole new level. There is no faster, more straight-to-the-point, or more fun way to learn Lightroom than with this groundbreaking book.

    Its thesis is that any sound can be generated from first principles, guided by analysis and synthesis. The text takes a practitioner's perspective, exploring the basic principles of making ordinary, everyday sounds using an easily accessed free software. Readers use the Pure Data (Pd) language to construct sound objects, which are more flexible and useful than recordings. Sound is considered as a process, rather than as data--an approach sometimes known as "procedural audio." Procedural sound is a living sound effect that can run as computer code and be changed in real time according to unpredictable events. Applications include video games, film, animation, and media in which sound is part of an interactive process. The book takes a practical, systematic approach to the subject, teaching by example and providing background information that offers a firm theoretical context for its pragmatic stance. [Many of the examples follow a pattern, beginning with a discussion of the nature and physics of a sound, proceeding through the development of models and the implementation of examples, to the final step of producing a Pure Data program for the desired sound. Different synthesis methods are discussed, analyzed, and refined throughout.] After mastering the techniques presented in Designing Sound, students will be able to build their own sound objects for use in interactive applications and other projects

    And everybody who has read it will agree that reports of the book’s death have been greatly exaggerated.”―Erik Spiekermann, typographerWe may love books, but do we know what lies behind them? In The Book, Keith Houston reveals that the paper, ink, thread, glue, and board from which a book is made tell as rich a story as the words on its pages―of civilizations, empires, human ingenuity, and madness. In an invitingly tactile history of this 2,000-year-old medium, Houston follows the development of writing, printing, the art of illustrations, and binding to show how we have moved from cuneiform tablets and papyrus scrolls to the hardcovers and paperbacks of today. Sure to delight book lovers of all stripes with its lush, full-color illustrations, The Book gives us the momentous and surprising history behind humanity’s most important―and universal―information technology.71 color illustrations

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.
