Allie loves everything about volleyball except hitting. She doesn't think she's good at it, and every time she messes up, her belief in her own abilities dwindles. Finally, she asks for help. Her idol, Nikki, agrees to coach her once a week. If Allie can learn to spike as well as she blocks, she could become one of the team's strongest players.

Is the Internet erasing national borders? Will the future of the Net be set by Internet engineers, rogue programmers, the United Nations, or powerful countries? Who's really in control of what's happening on the Net? In this provocative new book, Jack Goldsmith and Tim Wu tell the fascinating story of the Internet's challenge to governmental rule in the 1990s, and the ensuing battles with governments around the world. It's a book about the fate of one idea--that the Internet might liberate us forever from government, borders, and even our physical selves. We learn of Google's struggles with the French government and Yahoo's capitulation to the Chinese regime; of how the European Union sets privacy standards on the Net for the entire world; and of eBay's struggles with fraud and how it slowly learned to trust the FBI. In a decade of events the original vision is uprooted, as governments time and time again assert their power to direct the future of the Internet. The destiny of the Internet over the next decades, argue Goldsmith and Wu, will reflect the interests of powerful nations and the conflicts within and between them. While acknowledging the many attractions of the earliest visions of the Internet, the authors describe the new order, and speaking to both its surprising virtues and unavoidable vices. Far from destroying the Internet, the experience of the last decade has lead to a quiet rediscovery of some of the oldest functions and justifications for territorial government. While territorial governments have unavoidable problems, it has proven hard to replace what legitimacy governments have, and harder yet to replace the system of rule of law that controls the unchecked evils of anarchy. While the Net will change some of the ways that territorial states govern, it will not diminish the oldest and most fundamental roles of government and challenges of governance. Well written and filled with fascinating examples, including colorful portraits of many key players in Internet history, this is a work that is bound to stir heated debate in the cyberspace community.

Great leaders embrace a higher purpose to win. The Net Promoter System shines as their guiding star. Few management ideas have spread so far and wide as the Net Promoter System (NPS). Since its conception almost two decades ago by customer loyalty guru Fred Reichheld, thousands of companies around the world have adopted it—from industrial titans such as Mercedes-Benz and Cummins to tech giants like Apple and Amazon to digital innovators such as Warby Parker and Peloton. Now, Reichheld has raised the bar yet again. In Winning on Purpose, he demonstrates that the primary purpose of a business should be to enrich the lives of its customers. Why? Because when customers feel this love, they come back for more and bring their friends—generating good profits. This is NPS 3.0 and it puts a new take on the age-old Golden Rule—treat customers the way you would want a loved one treated—at the heart of enduring business success. As the compelling examples in this book illustrate, companies with superior NPS consistently deliver higher returns to shareholders across a wide array of industries. But winning on purpose isn't easy. Reichheld also explains why many NPS practitioners achieve just a small fraction of the system's full potential, and he presents the newest thinking and best practices for doing NPS right. He unveils the Earned Growth Rate (EGR): the first reliable, complementary accounting measure that can truly leverage the power of NPS. With keen insight and moving personal stories, Reichheld advances the thinking and practice of NPS. Winning on Purpose is your indispensable guide for inspiring customer love within your own teams and using Net Promoter to achieve both personal and business success.

#1 New York Times Bestseller Over 10 million copies sold In this generation-defining self-help guide, a superstar blogger cuts through the crap to show us how to stop trying to be "positive" all the time so that we can truly become better, happier people. For decades, we’ve been told that positive thinking is the key to a happy, rich life. "F**k positivity," Mark Manson says. "Let’s be honest, shit is f**ked and we have to live with it." In his wildly popular Internet blog, Manson doesn’t sugarcoat or equivocate. He tells it like it is—a dose of raw, refreshing, honest truth that is sorely lacking today. The Subtle Art of Not Giving a F**k is his antidote to the coddling, let’s-all-feel-good mindset that has infected American society and spoiled a generation, rewarding them with gold medals just for showing up. Manson makes the argument, backed both by academic research and well-timed poop jokes, that improving our lives hinges not on our ability to turn lemons into lemonade, but on learning to stomach lemons better. Human beings are flawed and limited—"not everybody can be extraordinary, there are winners and losers in society, and some of it is not fair or your fault." Manson advises us to get to know our limitations and accept them. Once we embrace our fears, faults, and uncertainties, once we stop running and avoiding and start confronting painful truths, we can begin to find the courage, perseverance, honesty, responsibility, curiosity, and forgiveness we seek. There are only so many things we can give a f**k about so we need to figure out which ones really matter, Manson makes clear. While money is nice, caring about what you do with your life is better, because true wealth is about experience. A much-needed grab-you-by-the-shoulders-and-look-you-in-the-eye moment of real-talk, filled with entertaining stories and profane, ruthless humor, The Subtle Art of Not Giving a F**k is a refreshing slap for a generation to help them lead contented, grounded lives.

Many problems in the sciences and engineering can be rephrased as optimization problems on matrix search spaces endowed with a so-called manifold structure. This book shows how to exploit the special structure of such problems to develop efficient numerical algorithms. It places careful emphasis on both the numerical formulation of the algorithm and its differential geometric abstraction--illustrating how good algorithms draw equally from the insights of differential geometry, optimization, and numerical analysis. Two more theoretical chapters provide readers with the background in differential geometry necessary to algorithmic development. In the other chapters, several well-known optimization methods such as steepest descent and conjugate gradients are generalized to abstract manifolds. The book provides a generic development of each of these methods, building upon the material of the geometric chapters. It then guides readers through the calculations that turn these geometrically formulated methods into concrete numerical algorithms. The state-of-the-art algorithms given as examples are competitive with the best existing algorithms for a selection of eigenspace problems in numerical linear algebra. Optimization Algorithms on Matrix Manifolds offers techniques with broad applications in linear algebra, signal processing, data mining, computer vision, and statistical analysis. It can serve as a graduate-level textbook and will be of interest to applied mathematicians, engineers, and computer scientists.
