Quite soon, the world's information infrastructure is going to reach a level of scale and complexity that will force scientists and engineers to approach it in an entirely new way. The familiar notions of command and control are being thwarted by realities of a faster, denser world of communication where choice, variety, and indeterminism rule. The myth of the machine that does exactly what we tell it has come to an end. What makes us think we can rely on all this technology? What keeps it together today, and how might it work tomorrow? Will we know how to build the next generation-or will we be lulled into a stupor of dependence brought about by its conveniences? In this book, Mark Burgess focuses on the impact of computers and information on our modern infrastructure by taking you from the roots of science to the principles behind system operation and design. To shape the future of technology, we need to understand how it works-or else what we don't understand will end up shaping us. This book explores this subject in three parts: Part I, Stability: describes the fundamentals of predictability, and why we have to give up the idea of control in its classical meaning Part II, Certainty: describes the science of what we can know, when we don't control everything, and how we make the best of life with only imperfect information Part III, Promises: explains how the concepts of stability and certainty may be combined to approach information infrastructure as a new kind of virtual material, restoring a continuity to human-computer systems so that society can rely on them.

Anomaly detection is the detective work of machine learning: finding the unusual, catching the fraud, discovering strange activity in large and complex datasets. But, unlike Sherlock Holmes, you may not know what the puzzle is, much less what "suspects" you're looking for. This O'Reilly report uses practical examples to explain how the underlying concepts of anomaly detection work. From banking security to natural sciences, medicine, and marketing, anomaly detection has many useful applications in this age of big data. And the search for anomalies will intensify once the Internet of Things spawns even more new types of data. The concepts described in this report will help you tackle anomaly detection in your own project. Use probabilistic models to predict what's normal and contrast that to what you observe Set an adaptive threshold to determine which data falls outside of the normal range, using the t-digest algorithm Establish normal fluctuations in complex systems and signals (such as an EKG) with a more adaptive probablistic model Use historical data to discover anomalies in sporadic event streams, such as web traffic Learn how to use deviations in expected behavior to trigger fraud alerts

What people are saying about The New How "How are you going to get rid of your Air Sandwich if you don't even know what it is? Provocative and practical at the same time." --Seth Godin, author of Linchpin "The New How is informative and provides exciting insights because the suggestions are practical and doable. Merchant gets the new reality--leadership fails not so much from flawed strategy as it does from failed processes of engagement from those responsible for implementing the strategy. In high-performing organizations, everyone acts like a leader, and they own the strategy and take actions to ensure its success. If you care about making a difference, read this book." --Barry Posner, author of The Leadership Challenge "Collaboration is a powerful, competitive weapon: this book shows you how to use it to win markets." --Mark Interrante, VP Content Products, Yahoo, Inc. "In a world in which the pace of change is ever quickening, collaboration, not control, is the route to a successful organization. This book tells you how to make your organization collaborative. And Nilofer Merchant's writing is a model of clarity." --Barry Schwartz, author of The Paradox of Choice: Why More Is Less "Want to transform your organization into a collaborative enterprise? Nilofer Merchant provides insightful and practical strategies in The New How." --Padmasree Warrior, CTO, Cisco Systems, Inc. "Merchant's book is a practical guide for the journey from strategy to implementation. The collaborative tools described here can help companies reach strategic success--and avoid pitfalls along the way." --Tom Kelley, General Manager, IDEO, and author of Ten Faces of Innovation Once in a generation, a book comes along that transforms the business landscape. For today's business leaders, The New How redefines the way companies create strategies and win new markets. Management gurus have always said "people matter." But those same gurus still relegate strategy to an elite set of executives who focus on frameworks, long presentations, and hierarchical approaches. Business strategy typically has been planned by corporate chiefs in annual meetings, and then dictated to managers to carry out. The New How turns that notion on its head. After many years of working with Apple, Adobe, HP, and many other companies, Nilofer Merchant discovered the secret sauce: the best way to create a winning strategy is to include employees at all levels, helping to create strategy they not only believe in, but are also equipped to implement. In The New How, Nilofer shows today's corporate directors, executives, and managers how they can transform their traditional, top-down approach to strategy planning and execution into collaborative "stratecution" that has proven to be significantly more effective. Enhance performance and outcomes by deflating the "air sandwich" between executives in the boardroom and employees Recognize that strategy and execution are thoroughly intertwined Understand how successful strategy is founded in effective idea selection-a pile of good ideas doesn't necessarily build good strategy Create company strategy and link it to targeted execution, using the practical models and techniques provided

It will also inspire organizations to change the way they function. Disruptive Possibilities: How Big Data Changes Everything takes you on a journey of discovery into the emerging world of big data, from its relatively simple technology to the ways it differs from cloud computing. But the big story of big data is the disruption of enterprise status quo, especially vendor-driven technology silos and budget-driven departmental silos. In the highly collaborative environment needed to make big data work, silos simply don't fit. Internet-scale computing offers incredible opportunity and a tremendous challenge - and it will soon become standard operating procedure in the enterprise. This book shows you what to expect.

To build electronic projects that can sense the physical world, you need to build circuits based around sensors: electronic components that react to physical phenomena by sending an electrical signal. Even with only basic electronic components, you can build useful and educational sensor projects. But if you incorporate Arduino or Raspberry Pi into your project, you can build much more sophisticated projects that can react in interesting ways and even connect to the Internet. This book starts by teaching you the basic electronic circuits to read and react to a sensor. It then goes on to show how to use Arduino to develop sensor systems, and wraps up by teaching you how to build sensor projects with the Linux-powered Raspberry Pi.

Views are virtual tables. That means they should be updatable, just as "real" or base tables are. In fact, view updatability isn't just desirable, it's crucial, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible. In stark contrast to this conventional wisdom, this book shows how views, just like base tables, can always be updated (so long as the updates don't violate any integrity constraints). More generally, it shows how updating always ought to work, regardless of whether the target is a base table or a view. The proposed scheme is 100% consistent with the relational model, but rather different from the way updating works in SQL products today.This book can: Help database products improve in the future Help with a "roll your own" implementation, absent such product improvements Make you aware of the crucial role of predicates and constraints Show you how relational products are really supposed to behave Anyone with a professional interest in the relational model, relational technology, or database systems in general can benefit from this book.
