    It is moving away from its current structure of documents and pages linked together, and towards a new structure that is built around people. This is a profound change that will affect how we create business strategy, design, marketing, and advertising. The reason for this shift is simple. For tens of thousands of years we've been social animals. The web, which is only 20 years old, is simply catching up with offline life.From travel to news to commerce, smart businesses are reorienting their efforts around people-around the social behavior of their customers and potential customers. In order to be successful, businesses will need to understand how people are connected, how their social network influences them, how the people closest to them influence them the most, and how it's more important for marketers to focus on small, connected groups of friends rather than looking for overly influential individuals.This book pulls together the latest research from leading universities and technology companies to describe how people are connected, and how ideas and brand messages spread through social networks. It shows readers how to rebuild their business around social behavior, and create products that people tell their friends about.

    The principal enhancement in Java 8 was the addition of functional programming constructs to Java's object-oriented roots. Java 7, 8, and 9 also introduced language features, such as the try-with-resources statement, the diamond operator for generic types, default and static methods in interfaces, the @SafeVarargs annotation, and modules. New library features include pervasive use of functional interfaces and streams, the java.time package for manipulating dates and times, and numerous minor enhancements such as convenience factory methods for collections. In this new edition of Effective Java, Bloch updates the work to take advantage of these new language and library features, and provides specific best practices for their use. Java's increased support for multiple paradigms increases the need for best-practices advice, and this book delivers. As in previous editions, each chapter consists of several "items," each presented in the form of a short, standalone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. Coverage includes:Updated techniques and best practices on classic topics, including objects, classes, methods, libraries, and generics How to avoid the traps and pitfalls of commonly misunderstood subtleties of the platform Focus on the language and its most fundamental libraries, such as java.lang and java.util

    Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today's Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today's Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, "not" mathematical proofs.

    Albert-László Barabási, the nation’s foremost expert in the new science of networks and author of Bursts, takes us on an intellectual adventure to prove that social networks, corporations, and living organisms are more similar than previously thought. Grasping a full understanding of network science will someday allow us to design blue-chip businesses, stop the outbreak of deadly diseases, and influence the exchange of ideas and information. Just as James Gleick and the Erdos–Rényi model brought the discovery of chaos theory to the general public, Linked tells the story of the true science of the future and of experiments in statistical mechanics on the internet, all vital parts of what would eventually be called the Barabási–Albert model.

    That's the startling thesis of this one-of-a-kind book that's sure to become a classic work of social commentary. Just as Marshall McLuhan forever altered our view of broadcast media, Weinberger shows that the new medium of the Web is not only altering social institutions such as business and government but, more important, is transforming bedrock concepts of our culture such as space, time, the public, and even reality itself. Weinberger introduces us to denizens of this new world, among them Zannah, whose online diary turns self-revelation into play; Tim Bray, whose map of the Web reveals what's at the heart of the new Web space; and Danny Yee and Claudiu Popa, part of the new breed of Web experts we trust despite their lack of qualifications. Through stories of life on the Web, an insightful take on some familiar (and some unfamiliar) Web sites, and a wicked sense of humor, Weinberger puts the Web into the social and intellectual context we need to begin assessing its true impact on our lives. The irony, according to Weinberger, is that this new technology is more in tune with our authentic selves than is the modern world. Funny, provocative, and ultimately hopeful, Small Pieces Loosely Joined makes us look at the Web -- and at life -- in a new light. From Small Pieces Loosely Joined: The Web has sent a jolt through our culture, zapping our economy, our ideas about the sharing of creative works, and possibly even institutions such as religion and government. Why? How do we explain the lightning charge of the Web? If it has fallen short of our initial hopes and fears about its transformational powers, why did it excite those hopes and fears in the first place? Why did this technology hit our culture like a bolt from Zeus? Suppose -- just suppose -- that the Web is a new world we're just beginning to inhabit . . . If the Web is changing bedrock concepts such as space, matter, time, perfection, public, knowledge, and morality -- each a chapter of this book -- no wonder we're so damn confused. That's as it should be. The Web is enabling us to rediscover what we've always known about being human: we are connected creatures in a connected world about which we care passionately . . . If this is true, then for all of the over-heated, exaggerated, manic-depressive coverage of the Web, we'd have to conclude that the Web in fact has not been hyped enough.
