Book Description
If you program in C++ you've been neglected. Test-driven development (TDD) is a modern software development practice that can dramatically reduce the number of defects in systems, produce more maintainable code, and give you the confidence to change your software to meet changing needs. But C++ programmers have been ignored by those promoting TDD--until now. In this book, Jeff Langr gives you hands-on lessons in the challenges and rewards of doing TDD in C++. Modern C++ Programming With Test-Driven Development, the only comprehensive treatment on TDD in C++ provides you with everything you need to know about TDD, and the challenges and benefits of implementing it in your C++ systems. Its many detailed code examples take you step-by-step from TDD basics to advanced concepts. As a veteran C++ programmer, you're already writing high-quality code, and you work hard to maintain code quality. It doesn't have to be that hard. In this book, you'll learn: how to use TDD to improve legacy C++ systems how to identify and deal with troublesome system dependencies how to do dependency injection, which is particularly tricky in C++ how to use testing tools for C++ that aid TDD new C++11 features that facilitate TDD As you grow in TDD mastery, you'll discover how to keep a massive C++ system from becoming a design mess over time, as well as particular C++ trouble spots to avoid. You'll find out how to prevent your tests from being a maintenance burden and how to think in TDD without giving up your hard-won C++ skills. Finally, you'll see how to grow and sustain TDD in your team. Whether you're a complete unit-testing novice or an experienced tester, this book will lead you to mastery of test-driven development in C++. What You Need A C++ compiler running under Windows or Linux, preferably one that supports C++11. Examples presented in the book were built under gcc 4.7.2. Google Mock 1.6 (downloadable for free; it contains Google Test as well) or an alternate C++ unit testing tool. Most examples in the book are written for Google Mock, but it isn't difficult to translate them to your tool of choice. A good programmer's editor or IDE. cmake, preferably. Of course, you can use your own preferred make too. CMakeLists.txt files are provided for each project. Examples provided were built using cmake version 2.8.9. Various freely-available third-party libraries are used as the basis for examples in the book. These include: cURL JsonCpp Boost (filesystem, date_time/gregorian, algorithm, assign) Several examples use the boost headers/libraries. Only one example uses cURL and JsonCpp.

Quaint, Exquisite

Category : Literary Criticism
Languages : en
Pages : 240

Book Description
How Japan captured the Victorian imagination and transformed Western aesthetics From the opening of trade with Britain in the 1850s, Japan occupied a unique and contradictory place in the Victorian imagination, regarded as both a rival empire and a cradle of exquisite beauty. Quaint, Exquisite explores the enduring impact of this dramatic encounter, showing how the rise of Japan led to a major transformation of Western aesthetics at the dawn of globalization. Drawing on philosophy, psychoanalysis, queer theory, textual criticism, and a wealth of in-depth archival research, Grace Lavery provides a radical new genealogy of aesthetic experience in modernity. She argues that the global popularity of Japanese art in the late nineteenth century reflected an imagined universal standard of taste that Kant described as the “subjective universal” condition of aesthetic judgment. The book features illuminating cultural histories of Gilbert and Sullivan’s Mikado, English derivations of the haiku, and retellings of the Madame Butterfly story, and sheds critical light on lesser-known figures such as Winnifred Eaton, an Anglo-Chinese novelist who wrote under the Japanese pseudonym Onoto Watanna, and Mikimoto Ryuzo, a Japanese enthusiast of the Victorian art critic John Ruskin. Lavery also explains the importance and symbolic power of such material objects as W. B. Yeats’s prized katana sword and the “Japanese vellum” luxury editions of Oscar Wilde. Quaint, Exquisite provides essential insights into the modern understanding of beauty as a vehicle for both intimacy and violence, and the lasting influence of Japanese forms today on writers and artists such as Quentin Tarantino.

The Mikado Method

Book Description
Summary The Mikado Method is a book written by the creators of this process. It describes a pragmatic, straightforward, and empirical method to plan and perform non-trivial technical improvements on an existing software system. The method has simple rules, but the applicability is vast. As you read, you'll practice a step-by-step system for identifying the scope and nature of your technical debt, mapping the key dependencies, and determining the safest way to approach the "Mikado"—your goal. About the Technology The game "pick-up sticks" is a good metaphor for the Mikado Method. You eliminate "technical debt" —the legacy problems embedded in nearly every software system— by following a set of easy-to-implement rules. You carefully extract each intertwined dependency until you expose the central issue, without collapsing the project. About the Book The Mikado Method presents a pragmatic process to plan and perform nontrivial technical improvements on an existing software system. The book helps you practice a step-by-step system for identifying the scope and nature of your technical debt, mapping the key dependencies, and determining a safe way to approach the "Mikado"—your goal. A natural by-product of this process is the Mikado Graph, a roadmap that reflects deep understanding of how your system works. This book builds on agile processes such as refactoring, TDD, and rapid feedback. It requires no special hardware or software and can be practiced by both small and large teams. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. What's Inside Understand your technical debt Surface the dependencies in legacy systems Isolate and resolve core concerns while creating minimal disruption Create a roadmap for your changes About the Authors Ola Ellnestam and Daniel Brolund are developers, coaches, and team leaders. They developed the Mikado Method in response to years of experience resolving technical debt in complex legacy systems.

W.S. Gilbert

Category : Composers

Pages : 424

Book Description
Sir William Schwenck Gilbert (1836-1911) was the most brilliant dramatist of Victorian England. A daring and cynical playwright, the forerunner of Oscar Wilde and George Bernard Shaw, he was also a prolific journalist and humorous poet (his Bab Ballads are still widely read), and he achieved worldwide fame through his long collaboration with the composer Arthur Sullivan, a collaboration that created such classics as H. M. S. Pinafore, The Mikado, and all the other Savoy operas. Now the story of this remarkable writer's life - and of his stormy relationship with Sullivan - is here chronicled by a renowned authority on Gilbert and on the theatrical and literary scene in Victorian London. For this biography, Jane W. Stedman has returned to original sources, has interviewed survivors, and has scoured a whole variety of Victorian periodicals for reviews, and personal comment. Gilbert emerges as a much more complex and interesting figure than has previously been thought. The book is a worthy companion piece to Arthur Jacobs's recent biography Arthur Sullivan: A Victorian Musician.
