    It has created a new, unprecedented cultural space that we are all a part of—even if we don’t participate, that is how we participate—but by which we’re continually surprised, betrayed, enriched, befuddled. We have churned through platforms and technologies and in turn been churned by them. And yet, the internet is us and always has been.In Lurking, Joanne McNeil digs deep and identifies the primary (if sometimes contradictory) concerns of people online: searching, safety, privacy, identity, community, anonymity, and visibility. She charts what it is that brought people online and what keeps us here even as the social equations of digital life—what we’re made to trade, knowingly or otherwise, for the benefits of the internet—have shifted radically beneath us. It is a story we are accustomed to hearing as tales of entrepreneurs and visionaries and dynamic and powerful corporations, but there is a more profound, intimate story that hasn’t yet been told.Long one of the most incisive, ferociously intelligent, and widely respected cultural critics online, McNeil here establishes a singular vision of who we are now, tells the stories of how we became us, and helps us start to figure out what we do now.

    Did you design your system to survivef a sudden rush of visitors from Digg or Slashdot? Or an influx of real world customers from 100 different countries?

    "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(R) WebSphere(R) 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 then builds on this foundation, and addresses modeling and design for complex systems and larger organizations.Specific topics covered include:Getting all team members to speak the same language Connecting model and implementation more deeply Sharpening key distinctions in a model Managing the lifecycle of a domain object Writing domain code that is safe to combine in elaborate ways Making complex code obvious and predictable Formulating a domain vision statement Distilling the core of a complex domain Digging out implicit concepts needed in the model Applying analysis patterns Relating design patterns to the model Maintaining model integrity in a large system Dealing with coexisting models on the same project Organizing systems with large-scale structures Recognizing and responding to modeling breakthroughs With this book in hand, object-oriented developers, system analysts, and designers will have the guidance they need to organize and focus their work, create rich and useful domain models, and leverage those models into quality, long-lasting software implementations.

    Creative Selection recounts the life of one of the few who worked behind the scenes, a highly-respected software engineer who worked in the final years the Steve Jobs era--the Golden Age of Apple.Ken Kocienda offers an inside look at Apple's creative process.

     We are living in a time of deep divisions. Americans are sorting themselves along racial, religious, and cultural lines, leading to a level of polarization that the country hasn't seen since the Civil War. Pundits and politicians are calling for us to come together, to find common purpose. But how, exactly, can this be done?In Palaces for the People, Eric Klinenberg suggests a way forward. He believes that the future of democratic societies rests not simply on shared values but on shared spaces: the libraries, childcare centers, bookstores, churches, synagogues, and parks where crucial, sometimes life-saving connections, are formed. These are places where people gather and linger, making friends across group lines and strengthening the entire community. Klinenberg calls this the "social infrastructure" When it is strong, neighborhoods flourish; when it is neglected, as it has been in recent years, families and individuals must fend for themselves.Klinenberg takes us around the globe--from a floating school in Bangladesh to an arts incubator in Chicago, from a soccer pitch in Queens to an evangelical church in Houston--to show how social infrastructure is helping to solve some of our most pressing challenges: isolation, crime, education, addiction, political polarization, and even climate change.Richly reported, elegantly written, and ultimately uplifting, Palaces for the People urges us to acknowledge the crucial role these spaces play in civic life. Our social infrastructure could be the key to bridging our seemingly unbridgeable divides--and safeguarding democracy.

    So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems?In this collection of essays and articles, key members of Google's Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You'll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient--lessons directly applicable to your organization.This book is divided into four sections: Introduction--Learn what site reliability engineering is and why it differs from conventional IT industry practicesPrinciples--Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE)Practices--Understand the theory and practice of an SRE's day-to-day work: building and operating large distributed computing systemsManagement--Explore Google's best practices for training, communication, and meetings that your organization can use

    Since 2001, newspaper and music revenues have fallen by 70%, book publishing, film and television profits have also fallen dramatically. Revenues at Google in this same period grew from $400 million to $74.5 billion. Google's YouTube today controls 60% of the streaming audio business and pays only 11% of the streaming audio revenues. More creative content is being consumed than ever before, but less revenue is flowing to creators and owners of the content.With the reallocation of money to monopoly platforms comes a shift in power. Google, Facebook, and Amazon now enjoy political power on par with Big Oil and Big Pharma, which in part explains how such a tremendous shift in revenues from artists to platforms could have been achieved and why it has gone unchallenged for so long.The stakes in this story go far beyond the livelihood of any one musician or journalist. As Taplin observes, the fact that more and more Americans receive their news, music and other forms of entertainment from a small group of companies poses a real threat to democracy. Move Fast and Break Things offers a vital, forward-thinking prescription for how artists can reclaim their audiences using knowledge of the past and a determination to work together. Using his own half-century career as a music and film producer and early pioneer of streaming video online, Taplin offers new ways to think about the design of the World Wide Web and specifically the way we live with the firms that dominate it.Table of contentsIntroduction1.

    Data Governance should not be about command-and-control, yet at times could become invasive or threatening to the work, people and culture of an organization. Non-Invasive Data Governance™ focuses on formalizing existing accountability for the management of data and improving formal communications, protection, and quality efforts through effective stewarding of data resources. Non-Invasive Data Governance will provide you with a complete set of tools to help you deliver a successful data governance program. Learn how: Steward responsibilities can be identified and recognized, formalized, and engaged according to their existing responsibility rather than being assigned or handed to people as more work. Governance of information can be applied to existing policies, standard operating procedures, practices, and methodologies, rather than being introduced or emphasized as new processes or methods. Governance of information can support all data integration, risk management, business intelligence and master data management activities rather than imposing inconsistent rigor to these initiatives. A practical and non-threatening approach can be applied to governing information and promoting stewardship of data as a cross-organization asset. Best practices and key concepts of this non-threatening approach can be communicated effectively to leverage strengths and address opportunities to improve.
