If you’ve been asked to maintain large and complex Hadoop clusters, this book is a must. Demand for operations-specific material has skyrocketed now that Hadoop is becoming the de facto standard for truly large-scale data processing in the data center. Eric Sammer, Principal Solution Architect at Cloudera, shows you the particulars of running Hadoop in production, from planning, installing, and configuring the system to providing ongoing maintenance. Rather than run through all possible scenarios, this pragmatic operations guide calls out what works, as demonstrated in critical deployments. Get a high-level overview of HDFS and MapReduce: why they exist and how they work Plan a Hadoop deployment, from hardware and OS selection to network requirements Learn setup and configuration details with a list of critical properties Manage resources by sharing a cluster across multiple groups Get a runbook of the most common cluster maintenance tasks Monitor Hadoop clusters—and learn troubleshooting with the help of real-world war stories Use basic tools and techniques to handle backup and catastrophic failure
For system administrators tasked with the job of maintaining large and complex Hadoop clusters, this book explains the particulars of Hadoop operations, from planning, installing, and configuring the system to providing ongoing maintenance.
Peace and Prosperity in an Age of Incivility presents a comprehensive theory about peace and prosperity. It asserts that three core political values-liberty, order, and equality- must be allocated by societies through law and policy. This book shows that the optimal allocation is pure balance. Balance of values provides the origin of the "democratic peace," the observation that democracies rarely fight each other and when they do, it is brief, does not escalate, and quickly results in a diplomatic resolution. By building on simple forms of spatial and game theories, this stunning analysis shows that the democratic peace is a "Nash equilibrium," where no player has an incentive to deviate from the solution, given the choices of other "players." Democracy, because it fosters compromise, drives the political values of liberty, order, and equality to intersect in perfect, or at least relative, balance. Maximum peace and prosperity is the consequence of balancing critical values. A nation's level of peace and prosperity, while perhaps not great, will be no greater than when these core values are in balance.
Trauma Radiology Companion, Second Edition is an easy-to-use, quick reference for trauma imaging designed for radiology residents, radiologists, and emergency physicians. The bulleted, key point format allows rapid access to succinct information for use in the clinical setting. Unlike traditional radiologic texts that emphasize image interpretation and follow a radiographic pattern, disease-oriented, anatomic site, or modality-specific approach, this handbook provides easy-to-look-up answers to common and uncommon questions that arise in day-to-day work, as well as in training and studying. The text is written in bulleted style to emphasize key points related to the common diagnoses encountered in the trauma setting. This new edition presents up-to-date clinical and radiologic information and images, represents all imaging modalities now in use, and includes current MDCT protocols. New chapters include the use of CT Angiography for diagnosis of Traumatic Aortic Injury, Focused Assessment with Sonography in Trauma (FAST) and evaluating the pregnant trauma patient. This manual is ideal for radiologists, radiology residents and fellows, emergency medicine physicians, trauma surgeons, and other emergency department care providers (nurses, physician assistants, nurse practitioners, etc.) who need a quick, but thorough overview of imaging the trauma patient!
The founder of Utne Reader chronicles his adventures on the frontlines of American culture—from the Vietnam era to the age of Trump—as a spiritual seeker, antiwar activist, and minor media celebrity. “Fascinating . . . a remarkable piece of social history.”—Bill McKibben, author of Falter: Has the Human Game Begun to Play Itself Out? Far Out Man is the story of a life-long seeker who was occasionally a finder as well. In 1984, Eric Utne founded Utne Reader, a digest of new ideas and fresh perspectives percolating in the arts, culture, politics, business, and spirituality. With the tag line “The Best of the Alternative Press,” the magazine was twice a finalist for a National Magazine Award and grew to more than 300,000 paid circulation. In the nineties, the magazine promoted the Neighborhood Salon Association to revive the endangered art of conversation and start a revolution in people’s living rooms. More than 18,000 people joined, comprising nearly 500 salons across North America. Utne devoted the magazine to bringing people together to help make the world a “little greener and a little kinder.” Far Out Man serves as a chronicle of both an individual life and a generation, covering the conflicts of the Vietnam era, the hopes and excesses of the sexual revolution and the Me Decade, the idealism and depredations of the entrepreneurial eighties and nineties, and the promise and perils of the digital age. Ultimately, Far Out Man is the story of Eric Utne’s lifelong search for hope, how he lost it, and what he found on the other side that sustains him in his darkest moments. It is a book dedicated to helping all seekers become finders.
This is a new edition of the first comprehensive text to show how the advances in molecular and cellular biology and in the basic neurosciences have brought the revolution in molecular medicine to the field of psychiatry. The book begins with a review of basic neuroscience and methods for studying neurobiology in human patients then proceeds to discussions of all major psychiatric syndromes with respect to knowledge of their etiology, pathophysiology, and treatment. Emphasis is placed on synthesizing information across numerous levels of analysis, including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, and behavior, and in translating information from the basic laboratory to the clinical laboratory and finally to clinical treatment. Editors Dennis Charney and Eric Nestle, along with their six section editors and over 150 contributors, have revised and updated all 80 chapters from the previous edition and have added new chapters on topics relating to, for example, genetics, experimental therapeutics, and late-life mood disorders. Both a textbook and a reference book, Neurobiology of Mental Illness is intended for psychiatrists, neuroscientists, and upper level students.
