    How Buildings Learn is a masterful new synthesis that proposes that buildings adapt best when constantly refined and reshaped by their occupants, and that architects can mature from being artists of space to becoming artists of time. From the connected farmhouses of New England to I.M. Pei's Media Lab, from "satisficing" to "form follows funding," from the evolution of bungalows to the invention of Santa Fe Style, from Low Road military surplus buildings to a High Road English classic like Chatsworth—this is a far-ranging survey of unexplored essential territory.More than any other human artifacts, buildings improve with time—if they're allowed to. How Buildings Learn shows how to work with time rather than against it.

    It describes the Disciplined Agile Delivery (DAD) process decision framework and then works through a case study describing a typical agile team’s experiences adopting a disciplined agile approach. The book describes how the team develops the first release of a mission-critical application while working in a legacy enterprise environment. It describes their experiences from beginning-to-end, starting with their initial team initiation efforts through construction and finally to deploying the solution into production. It also describes how the team stays together for future releases, overviewing their process improvement efforts from their Scrum-based beginnings through to a lean continuous delivery approach that fits in with their organization’s evolving DevOps strategy. The DAD framework is a hybrid of existing methods such as Scrum, Kanban, Agile Modeling, SAFe, Extreme Programming, Agile Data, Unified Process and many others. DAD provides the flexibility to use various approaches and plugs the gaps not addressed by mainstream agile methods. In a nutshell, DAD is “pragmatic agile.” DAD describes proven strategies to adapt and scale your agile initiatives to suit the unique realities of your enterprise without having to figure it all out by yourself. Here’s an overview of what each chapter covers: * Chapter 1: Introduction. This chapter provides a quick overview of the book and a brief history of Disciplined Agile. * Chapter 2: Reality over Rhetoric. This chapter explores several common myths about DAD and more importantly disproves them. * Chapter 3: Disciplined Agile Delivery in a Nutshell. This chapter provides a brief yet comprehensive overview of the DAD framework. * Chapter 4: Introduction to the Case Study. This chapter introduces us to the team, describes the market opportunity that they hope to address, and describes the environment in which they’re working. * Chapter 5: Inception. The team’s initiation effort includes initial requirements modeling and planning with their stakeholders in a streamlined manner, initial architecture modeling, setting up their physical work environment, setting up the start of their tooling infrastructure, initial risk identification, and finally securing stakeholder support and funding for the rest of the first release. * Chapters 6 through 10: Construction. These chapters each describe a single Construction iteration, sharing the team’s experiences during each of those two-week timeboxes. * Chapter 11: Transition. The two-week transition phase focuses on final testing and fixing, training the support/help-desk staff, finishing a few short end-user “how to” videos, and deploying the solution into production. * Chapter 12: Future Releases. This chapter overviews the team’s improvement efforts over the next few releases, describing how they evolve from the agile Scrum-based lifecycle to a leaner approach and eventually to continuous delivery. * Chapter 13: Closing Thoughts. This chapter overviews the disciplined agile resources that are available to you. * Appendix: The Disciplined Agile IT Department. This short appendix overviews our ongoing work on the Disciplined Agile framework to address the full scope of an IT department. At 102 pages, you should find this book to be a quick, informative read.

    Quake, World of Warcraft, Eve Online, and other online games not only offered author Jim Rossignol an excellent escape from the tedium of office life. They also provided him with a diverse global community and a job—as a games journalist.Part personal history, part travel narrative, part philosophical reflection on the meaning of play, This Gaming Life describes Rossignol’s encounters in three cities: London, Seoul, and Reykjavik. From his days as a Quake genius in London’s increasingly corporate gaming culture; to Korea, where gaming is a high-stakes televised national sport; to Iceland, the home of his ultimate obsession, the idiosyncratic and beguiling Eve Online, Rossignol introduces us to a vivid and largely undocumented world of gaming lives.Torn between unabashed optimism about the future of games and lingering doubts about whether they are just a waste of time, This Gaming Life also raises important questions about this new and vital cultural form. Should we celebrate the “serious” educational, social, and cultural value of games, as academics and journalists are beginning to do? Or do these high-minded justifications simply perpetuate the stereotype of games as a lesser form of fun? In this beautifully written, richly detailed, and inspiring book, Rossignol brings these abstract questions to life, immersing us in a vibrant landscape of gaming experiences.“We need more writers like Jim Rossignol, writers who are intimately familiar with gaming, conversant in the latest research surrounding games, and able to write cogently and interestingly about the experience of playing as well as the deeper significance of games.”—Chris Baker, Wired“This Gaming Life is a fascinating and eye-opening look into the real human impact of gaming culture. Traveling the globe and drawing anecdotes from many walks of life, Rossignol takes us beyond the media hype and into the lives of real people whose lives have been changed by gaming. The results may surprise you.”—Raph Koster, game designer and author of A Theory of Fun for Game Design “Is obsessive video gaming a character flaw? In This Gaming Life, Jim Rossignol answers with an emphatic ‘no,’ and offers a passionate and engaging defense of what is too often considered a ‘bad habit’ or ‘guilty pleasure.’”—Joshua Davis, author of The Underdog“This is a wonderfully literate look at gaming cultures, which you don't have to be a gamer to enjoy. The Korea section blew my mind.”—John Seabrook, New Yorker staff writer and author of Flash of Genius and Other True Stories of Inventiondigitalculturebooks is an imprint of the University of Michigan Press and the Scholarly Publishing Office of the University of Michigan Library dedicated to publishing innovative and accessible work exploring new media and their impact on society, culture, and scholarly communication.

    Teaches developers how to build database-driven web applications using two of today's most popular open-source software tools, PHP and MySQL.

    The rapid maturation of PHP has created a skeptical population of users from more traditional enterprise languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP. While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on scaling PHP for large-scale, business-critical systems. Schlossnagle's Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

    Richard Holloway retells the entire history of religion—from the dawn of religious belief to the twenty-first century—with deepest respect and a keen commitment to accuracy. Writing for those with faith and those without, and especially for young readers, he encourages curiosity and tolerance, accentuates nuance and mystery, and calmly restores a sense of the value of faith. Ranging far beyond the major world religions of Judaism, Islam, Christianity, Buddhism, and Hinduism, Holloway also examines where religious belief comes from, the search for meaning throughout history, today’s fascinations with Scientology and creationism, religiously motivated violence, hostilities between religious people and secularists, and more. Holloway proves an empathic yet discerning guide to the enduring significance of faith and its power from ancient times to our own.
