Beginning with an introduction to array formulas, this manual examines topics such as how they differ from ordinary formulas, the benefits and drawbacks of their use, functions that can and cannot handle array calculations, and array constants and functions. Among the practical applications surveyed include how to extract data from tables and unique lists, how to get results that match any criteria, and how to utilize various methods for unique counts. This book contains 529 screen shots.

    He turned to the audience and shared his idea with the simple slogan: "Coinbase, the easiest way to get started with Bitcoin."For a moment late in 2018, one Bitcoin, which physically amounts to a few electrons blipping on a tiny bit of silicon, was worth $20,000—the same as a pound of gold. Libertarian technologists who believed Bitcoin would be the foundation of a new world order saw the moment as an apotheosis. Everyone else saw a bubble. Everyone else was right, and the bubble burst. But Bitcoin survived, and the battle for its soul rages on. True believers view it as the foundation for a future economy freed from the vicissitudes of Wall Street and government control of currency. Pragmatists believe that bringing Bitcoin into the mainstream will, as the Silicon Valley cliche goes, make the world a better place. But they need buy-in from traditional institutional systems that can prevent the crypto world from devolving into the lawless criminal bazaar it was becoming during the bubble.Journalist Jeff John Roberts drops us into the unfolding drama as he follows the rise, fall, and rebirth of cryptocurrency through the experiences of major players across the globe. We follow Silicon Valley entrepreneur Brian Armstrong and his company, Coinbase, as it tries to make Bitcoin easy to use and available to all while fighting off hackers, thieves, and zealots. Roberts keenly observes the importance of leadership and strategy in the developing field of virtual currencies and what happens when these guardrails are missing. His ability to explain crypto technology clearly and lay out the ramifications of its infiltration into the global financial system makes this book a must-read for leaders in every industry. The amazing story—full of startup hijinks, shady investors, billionaire bros and their Lambos, closed-door meetings with Jamie Dimon, hacking (so much hacking!), Libertarian free-state utopias in New Hampshire, and the Winklevoss twins—make this a page turner that readers will love.

    

    

    Every piece of the web application stack, from HTTP requests to browser-side scripts, comes with important yet subtle security consequences. To keep users safe, it is essential for developers to confidently navigate this landscape.In The Tangled Web, Michal Zalewski, one of the world's top browser security experts, offers a compelling narrative that explains exactly how browsers work and why they're fundamentally insecure. Rather than dispense simplistic advice on vulnerabilities, Zalewski examines the entire browser security model, revealing weak points and providing crucial information for shoring up web application security. You'll learn how to:Perform common but surprisingly complex tasks such as URL parsing and HTML sanitization Use modern security features like Strict Transport Security, Content Security Policy, and Cross-Origin Resource Sharing Leverage many variants of the same-origin policy to safely compartmentalize complex web applications and protect user credentials in case of XSS bugs Build mashups and embed gadgets without getting stung by the tricky frame navigation policy Embed or host user-supplied content without running into the trap of content sniffing For quick reference, "Security Engineering Cheat Sheets" at the end of each chapter offer ready solutions to problems you're most likely to encounter. With coverage extending as far as planned HTML5 features, The Tangled Web will help you create secure web applications that stand the test of time.

    Jeffrey Tucker, CLO of Liberty.me and Distinguished Fellow of the Foundation for Economic Education, argues that peer-to-peer technology is forging a new and brighter social, economic, and political order. People tend to look at innovations in isolation. Here is my new e-reader. Here is an app I like. Here is my new mobile device and computer. Even bitcoin is routinely analyzed and explained in terms of its properties as an alternative to national currencies, as if there were no more than that at stake.But actually there is a historical trajectory at work here, one that we can trace through its logic, implementation, and spread. It’s the same logic that led from the dial phone at the county store, operated by people pulling and plugging in wires, to the wireless smartphone in your pocket that contains the whole store of human knowledge. It’s all about technology in the service of individuation.Once you understand the driving ethos — voluntarism, creativity, networks, individual initiative — you can see the outlines of a new social structure emerging within our time, an order that defies a century of top-down planning and nation-state restrictionism.It is coming about not because of political reform. It is not any one person’s creation. It is not happening because a group of elite intellectuals advocated it. The new world is emerging organically, and messily, from the ground up, as an extension of unrelenting creativity and experimentation. In the end, it is emerging out of an anarchist order that no one in particular controls and no one in particular can fully understand."The building of universal prosperity is a process that unfolds bit by bit through decentralized decision making and improvements at the margin through trial-and-error. To continue this process, we need understanding, patience, and dreams. Jeffrey Tucker’s book is an excellent guide to all three.” ~ Patrick Byrne, CEO of Overstock.com, from the introduction. “In Bitcoin’s brief existence Jeffrey Tucker has become one of its leading proponents. In this book we can see exactly why. Many people think of bitcoin as just money, but Mr. Tucker is able to explain, in a way that is easily understandable by all, the tsunami of innovation that bitcoin is about to release upon the world.” ~ Roger Ver, Bitcoin investor, from the Foreword

    But the principles and practices of software architecting–what the authors call the “science of hard decisions”–have been evolving for cloud, mobile, and other shifts. Now fully revised and updated, this book shares the knowledge and real-world perspectives that enable you to design for success–and deliver more successful solutions. In this fully updated Second Edition, you will: Learn how only a deep understanding of domain can lead to appropriate architecture Examine domain-driven design in both theory and implementation Shift your approach to code first, model later–including multilayer architecture Capture the benefits of prioritizing software maintainability See how readability, testability, and extensibility lead to code quality Take a user experience (UX) first approach, rather than designing for data Review patterns for organizing business logic Use event sourcing and CQRS together to model complex business domains more effectively Delve inside the persistence layer, including patterns and implementation.

    The patterns apply to the development process as well as to architecture and coding practices. The content is based on a presentation developed by Scott Guthrie and delivered by him at the Norwegian Developers Conference (NDC) in June of 2013 (part 1, part 2), and at Microsoft Tech Ed Australia in September 2013 (part 1, part 2). Many others updated and augmented the content while transitioning it from video to written form. Who should read this book Developers who are curious about developing for the cloud, are considering a move to the cloud, or are new to cloud development will find here a concise overview of the most important concepts and practices they need to know. The concepts are illustrated with concrete examples, and each chapter includes links to other resources that provide more in-depth information. The examples and the links to additional resources are for Microsoft frameworks and services, but the principles illustrated apply to other web development frameworks and cloud environments as well. Developers who are already developing for the cloud may find ideas here that will help make them more successful. Each chapter in the series can be read independently, so you can pick and choose topics that you're interested in. Anyone who watched Scott Guthrie's "Building Real World Cloud Apps with Windows Azure" presentation and wants more details and updated information will find that here. Assumptions This ebook expects that you have experience developing web applications by using Visual Studio and ASP.NET. Familiarity with C# would be helpful in places.

    But facing the sea change that AI will bring can be paralyzing. How should companies set strategies, governments design policies, and people plan their lives for a world so different from what we know? In the face of such uncertainty, many analysts either cower in fear or predict an impossibly sunny future.But in Prediction Machines, three eminent economists recast the rise of AI as a drop in the cost of prediction. With this single, masterful stroke, they lift the curtain on the AI-is-magic hype and show how basic tools from economics provide clarity about the AI revolution and a basis for action by CEOs, managers, policy makers, investors, and entrepreneurs.When AI is framed as cheap prediction, its extraordinary potential becomes clear: Prediction is at the heart of making decisions under uncertainty. Our businesses and personal lives are riddled with such decisions. Prediction tools increase productivity--operating machines, handling documents, communicating with customers. Uncertainty constrains strategy. Better prediction creates opportunities for new business structures and strategies to compete. Penetrating, fun, and always insightful and practical, Prediction Machines follows its inescapable logic to explain how to navigate the changes on the horizon. The impact of AI will be profound, but the economic framework for understanding it is surprisingly simple.
