Unix Power Tools

Unlock the Secrets of Linux System Programming and Take Your Coding Skills to the Next Level Do you use Linux, but not really understand it? Have you ever wondered how ls -l' knows everything does? Could you explain to a coworker why ls' and find' can be external commands but cd' and umask' must be built into the shell? The answers to these questions, and more, are in Linux Application Programming by Example, Second Edition. Purposely avoiding Too Much Information (TMI) this book tells you exactly what you need to know--no more and no less--about the fundamental Linux system programming APIs. Following the latest POSIX standard, author Arnold Robbins explains how the basic file, process, IPC and networking APIs work. Wherever possible, he demonstrates the use of the APIs with code drawn from real programs (V7 Unix, BSD Unix, and GNU). When not possible, the author provides small, clearly documented and annotated, standalone example programs of his own. The author focuses on both

From foundations in critical thinking skills to practical tools and real-life perspectives, this book empowers young adult readers to be independent media users. During the recent presidential election, "media literacy" became a buzzword that signified the threat media manipulation posed to democratic processes. Meanwhile, statistical research has shown that 8 to 18 year-olds pack more than eleven hours with some form of media into each day by "media multitasking." Young people are not only eager and interested to learn about and discuss the realities of media ownership, production, and distribution, they also deserve to understand differential power structures in how media influences our culture. The Media and Me provides readers with the tools and perspectives to be empowered and autonomous media users. The book explores critical inquiry skills to help young people form a multidimensional comprehension of what they read and watch, opportunities to see others like them making change,

Concerns about unaccountable executive power have featured recurrently in political debates from the American founding to today. For many, presidents' use of unilateral power threatens American democracy. No Blank Check advances a new perspective: Instead of finding Americans apathetic towards how presidents exercise power, it shows the public is deeply concerned with core democratic values. Drawing on data from original surveys, innovative experiments, historical polls, and contexts outside the United States, the book highlights Americans' skepticism towards presidential power. This skepticism results in a public that punishes unilaterally minded presidents and the policies they pursue. By departing from existing theories of presidential power which acknowledge only institutional constraints, this timely and revealing book demonstrates the public's capacity to tame the unilateral impulses of even the most ambitious presidents. Ultimately, when it comes to exercising power, the public

Techniques for applying mathematical concepts in the real world: six rarely taught but crucial tools for analysis, research, and problem-solving.Many young graduates leave school with a solid knowledge of mathematical concepts but struggle to apply these concepts in practice. Real scientific and engineering problems are different from those found in textbooks: they are messier, take longer to solve, and standard solution recipes might not apply. This book fills the gap between what is taught in the typical college curriculum and what a practicing engineer or scientist needs to know. It presents six powerful tools for analysis, research, and problem-solving in the real world: dimensional analysis, limiting cases, symmetry, scaling, making order of magnitude estimates, and the method of successive approximations. The book does not focus on formulaic manipulations of equations, but emphasizes analysis and explores connections between the equations and the application. Each chapter introdu

Does power sharing bring peace? Policymakers around the world seem to think so. Yet, while there are many successful examples of power sharing in multi-ethnic states, such as Switzerland, South Africa and Indonesia, other instances show that such arrangements offer no guarantee against violent conflict, including Rwanda, Yugoslavia, Zimbabwe and South Sudan. Given this mixed record, it is not surprising that scholars disagree as to whether power sharing actually reduces conflict. Based on systematic data and innovative methods, this book comes to a mostly positive conclusion by focusing on practices rather than merely formal institutions, studying power sharing's preventive effect, analyzing how power sharing is invoked in anticipation of conflict, and by showing that territorial power sharing can be effective if combined with inclusion at the center. The authors' findings demonstrate that power sharing is usually the best option to reduce and prevent civil conflict in divided states.

Cultural rights promote cultural and scientific creativity. Transformative and empowering, they also enable the pursuit of knowledge and understanding, thereby working as atrocity prevention tools. The Transforming Power of Cultural Rights argues that this gives these rights a central role to play in promoting the full human personality and in realizing all other human rights. Looking at the work of the UN Special Rapporteurs in the field of cultural rights as well as UNESCO's efforts, Helle Porsdam addresses the question of how a universal human rights agenda can include a dialogue that recognizes the importance of cultural diversity without sliding into cultural relativism. She argues that cultural rights offer a useful international arena and discourse in which to explain and negotiate cultural meanings when controversies arise. This places them at the center of human rights - and at the center of law and humanities.

Power is the central organizing concept for politics. However, despite decades of debate across political science, sociology, and philosophy, scholars have not yet settled on a proper definition of power. Existing definitions fail because they are either circular or so far removed from theordinary, quotidien meaning of power that they cannot credibly claim to be about the same concept. Political science has looked at how power works, but according to Guido Parietti, fails to define what power means. In On the Concept of Power, Parietti proposes a more proper definition of power--as the condition of having available possibilities and representing them as such--and examines its implications for the study of politics, both empirical and normative. By neglecting the category of possibility, significant portions of political science and philosophy become incapable of conceptualizing power, and therefore politics. Specifically, Parietti asserts that the main failure of political science is i

Light scattering is one of the most well-studied phenomena in nature. It occupies a central place in optical physics, and plays a key role in multiple fields of science and engineering. This volume presents a comprehensive introduction to the subject. For the first time, the authors bring together in a self-contained and systematic manner, the physical concepts and mathematical tools that are used in the modern theory of light scattering and transport, presenting them in a clear, accessible style. The power of these tools is demonstrated by a framework that links various aspects of the subject: scattering theory to radiative transport, radiative transport to diffusion, and field correlations to the statistics of speckle patterns. For graduate students and researchers in optical physics and optical engineering, this book is an invaluable resource on the interaction of light with complex media and the theory of light scattering in disordered and complex systems.

The real world is perceived and broken down as data, models and algorithms in the eyes of physicists and engineers. Data is noisy by nature and classical statistical tools have so far been successful in dealing with relatively smaller levels of randomness. The recent emergence of Big Data and the required computing power to analyse them have rendered classical tools outdated and insufficient. Tools such as random matrix theory and the study of large sample covariance matrices can efficiently process these big data sets and help make sense of modern, deep learning algorithms. Presenting an introductory calculus course for random matrices, the book focusses on modern concepts in matrix theory, generalising the standard concept of probabilistic independence to non-commuting random variables. Concretely worked out examples and applications to financial engineering and portfolio construction make this unique book an essential tool for physicists, engineers, data analysts, and economists.

The Power of Ritual in Prehistory is the first book in nearly a century to deal with traditional secret societies from a comparative perspective and the first from an archaeological viewpoint. Providing a clear definition, as well as the material signatures, of ethnographic secret societies, Brian Hayden demonstrates how they worked, what motivated their organizers, and what tactics they used to obtain what they wanted. He shows that far from working for the welfare of their communities, traditional secret societies emerged as predatory organizations operated for the benefit of their own members. Moreover, and contrary to the prevailing ideas that prehistoric rituals were used to integrate communities, Hayden demonstrates how traditional secret societies created divisiveness and inequalities. They were one of the key tools for increasing political control leading to chiefdoms, states, and world religions. Hayden's conclusions will be eye-opening, not only for archaeologists, but also f

Language is not simply a tool for communication - symbolic power struggles underlie any speech act, discourse move, or verbal interaction, be it in face-to-face conversations, online tweets or political debates. This book provides a clear and accessible introduction to the topic of language and power from an applied linguistics perspective. It is clearly split into three sections: the power of symbolic representation, the power of symbolic action and the power to create symbolic reality. It draws upon a wide range of existing work by philosophers, sociolinguists, sociologists and applied linguists, and includes current real-world examples, to provide a fresh insight into a topic that is of particular significance and interest in the current political climate and in our increasingly digital age. The book shows the workings of language as symbolic power in educational, social, cultural and political settings and discusses ways to respond to and even resist symbolic violence.

Power is an inherent feature of social interactions, yet it is hard to define and therefore understand. This book is the first to organize current interdisciplinary theorizing and research about power from leading academics in areas such as social psychology, communications, family studies, and public health. It also focuses exclusively on how power operates and affects close relationship processes, while the theoretical insights provided point the way toward new lines of research and understanding. Using specific examples to illustrate complex theoretical explanations and supplying thorough descriptions of the existing literature on power in close relationships, this book is an essential resource for researchers, professionals, students, or laypeople seeking to better understand how power operates in those relationships that are most important to us.
