    In the last decade, it has utterly transformed our lives. But what real effects is it having on our social world?What does it mean to be a modern family when dinner table conversations take place over smartphones? What happens to privacy when we readily share our personal lives with friends and corporations? Are our Facebook updates and Twitterings inspiring revolution or are they just a symptom of our global narcissism? What counts as celebrity, when everyone can have a following or be a paparazzo? And what happens to relationships when love, sex and hate can be mediated by a computer?Social psychologist Aleks Krotoski has spent a decade untangling the effects of the Web on how we work, live and play. In this groundbreaking book, she uncovers how much humanity has - and hasn't - changed because of our increasingly co-dependent relationship with the computer. In Untangling the Web, she tells the story of how the network became woven in our lives, and what it means to be alive in the age of the Internet.

    On Twitter, word can spread faster than wildfire. Companies no longer have the option of ignoring the conversation. Unlike other hot social media spaces, "Twitterville" is dominated by professionals, not students. And despite its size, it still feels like a small town. Twitter allows people to interact much the way they do face-to-face, honestly and authentically. One minute, you re com- plaining about the weather with local friends, the next, you re talking shop with a colleague based halfway across the globe. No matter where you re from or what you do for a living, you will find conversations on Twitter that are valuable. Despite the millions of people joining the site, you ll quickly find the ones who can make a difference to you. Social media writer Shel Israel shares revealing stories of "Twitterville" residents, from CEOs to the student who became the first to report the devastation of the Szechuan earthquake; from visionaries trying to raise money for a cause to citizen journalists who outshine traditional media companies. Israel introduces you to trailblazers such as: . Frank Eliason, who used Twitter to reverse Comcast s blemished customer service reputation . Bill Fergus, who was on the team at Henry Ford Medical Center during the first live tweeted surgery . Scott Monty, social media officer for Ford, who held off a mob of misinformed Ranger fans and averted a PR crisis . Connie Reece, who used Twitter to raise tens of thousands of dollars for cancer patients in need . The Coffee Groundz, a Houston-area coffee shop that uses Twitter to pack the tables (and fight off Starbucks) "Twitterville" features many true stories as dramatic as these. But it also recounts those of ordinary businesspeople who use Twitter to get closer to their customers. And it explains how global neighborhoods will make geography increasingly irrelevant. It even explains why people sometimes really do care what you had for lunch."

    We depend on it for everything we do. We have reengineered our business, governance, and social relations around a planetary network unlike any before it. But there are dangers looming, and malign forces are threatening to transform this extraordinary domain.In Black Code, Ronald J. Deibert, a leading expert on digital technology, security, and human rights, lifts the lid on cyberspace and shows what’s at stake for Internet users and citizens. As cyberspace develops in unprecedented ways, powerful agents are scrambling for control. Predatory cyber criminal gangs such as Koobface have made social media their stalking ground. The discovery of Stuxnet, a computer worm reportedly developed by Israel and the United States and aimed at Iran’s nuclear facilities, showed that state cyberwar is now a very real possibility. Governments and corporations are in collusion and are setting the rules of the road behind closed doors.This is not the way it was supposed to be. The Internet’s original promise of a global commons of shared knowledge and communications is now under threat. Drawing on the first-hand experiences of one of the most important protagonists in the battle — the Citizen Lab and its global network of frontline researchers, who have spent more than a decade cracking cyber espionage rings and uncovering attacks on citizens and NGOs worldwide — Black Code takes readers on a fascinating journey into the battle for cyberspace. Thought-provoking, compelling, and sometimes frightening, it is a wakeup call to citizens who have come to take the Internet for granted. Cyberspace is ours, it is what we make of it, Deibert argues, and we need to act now before it slips through our grasp.

    On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, author C.J. Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:Should database access granted be through views instead of base tables? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Could you write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports "quantified comparisons," but they're better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don't support them properly. What can you do to resolve this situation? Database theory and practice have evolved since Edgar Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.

    The way that we make decisions as humans affects everything from our emotions to our security.

    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.
