Tous nos pas dans le cyberespace sont suivis, enregistrés, analysés, et nos profils se monnayent en permanence. Comment en est-on arrivé là ? Les évolutions techniques ont permis à plus de quatre milliards d'internautes de communiquer, de rechercher de l'information ou de se distraire. Dans le même temps, la concentration des acteurs et les intérêts commerciaux ont développé une industrie mondiale des traces. Les États se sont engouffrés dans cette logique et ont mis en oeuvre partout dans le monde des outils de surveillance de masse. Le livre de Tristan Nitot porte un regard lucide et analytique sur la situation de surveillance ; il nous offre également des moyens de reprendre le contrôle de notre vie numérique. Comprendre et agir sont les deux faces de cet ouvrage, qui le rendent indispensable à celles et ceux qui veulent défendre les libertés dans un monde numérique.
Patterns of Commoning
What accounts for the persistence and spread of "commoning," the irrepressible desire of people to collaborate and share to meet everyday needs? How are the more successful projects governed? And why are so many people embracing the commons as a powerful strategy for building a fair, humane and Earth-respecting social order? In more than fifty original essays, Patterns of Commoning addresses these questions and probes the inner complexities of this timeless social paradigm. The book surveys some of the most notable, inspiring commons around the world, from alternative currencies and open design and manufacturing, to centuries-old community forests and co-learning commons - and dozens of others. David Bollier (www.bollier.org) is an American author, activist and independent scholar who has studied the commons for nearly twenty years. Silke Helfrich (commonsblog.wordpress.com) is a German author and independent activist of the commons who blogs at www.commonsblog.de, and cofounder of the Commons-Institut in Germany. With Michel Bauwens, Bollier and Helfrich are cofounders of the Common Strategies Group. For more information, go to the book's website, Patterns of Commoning (www.patternsofcommoning.org)
ROS Robotics By Example
Bring life to your robot using ROS robotic applications About This Book This book will help you boost your knowledge of ROS and give you advanced practical experience you can apply to your ROS robot platforms This is the only book that offers you step-by-step instructions to solidify your ROS understanding and gain experience using ROS tools From eminent authors, this book offers you a plethora of fun-filled examples to make your own quadcopter, turtlebot, and two-armed robots Who This Book Is For If you are a robotics developer, whether a hobbyist, researchers or professional, and are interested in learning about ROS through a hands-on approach, then this book is for you. You are encouraged to have a working knowledge of GNU/Linux systems and Python. What You Will Learn Get to know the fundamentals of ROS and apply its concepts to real robot examples Control a mobile robot to navigate autonomously in an environment Model your robot designs using URDF and Xacro, and operate them in a ROS Gazebo simulation Control a 7 degree-of-freedom robot arm for visual servoing Fly a quadcopter to autonomous waypoints Gain working knowledge of ROS tools such as Gazebo, rviz, rqt, and Move-It Control robots with mobile devices and controller boards In Detail The visionaries who created ROS developed a framework for robotics centered on the commonality of robotic systems and exploited this commonality in ROS to expedite the development of future robotic systems. From the fundamental concepts to advanced practical experience, this book will provide you with an incremental knowledge of the ROS framework, the backbone of the robotics evolution. ROS standardizes many layers of robotics functionality from low-level device drivers to process control to message passing to software package management. This book provides step-by-step examples of mobile, armed, and flying robots, describing the ROS implementation as the basic model for other robots of these types. By controlling these robots, whether in simulation or in reality, you will use ROS to drive, move, and fly robots using ROS control. Style and approach This is an easy-to-follow guide with hands-on examples of ROS robots, both real and in simulation.
The Power of Now
To make the journey into the Now we will need to leave our analytical mind and its false created self, the ego, behind. From the very first page of Eckhart Tolle's extraordinary book, we move rapidly into a significantly higher altitude where we breathe a lighter air. We become connected to the indestructible essence of our Being, “The eternal, ever present One Life beyond the myriad forms of life that are subject to birth and death.” Although the journey is challenging, Eckhart Tolle uses simple language and an easy question and answer format to guide us. A word of mouth phenomenon since its first publication, The Power of Now is one of those rare books with the power to create an experience in readers, one that can radically change their lives for the better.
A series of essays in which Barthes seeks to tear away masks and demystify the signs, signals, gestures and messages through which western society sustains, sells, identifies and yet obscures itself.
The Meaning of the Library
From Greek and Roman times to the digital era, the library has remained central to knowledge, scholarship, and the imagination. The Meaning of the Library is a generously illustrated examination of this key institution of Western culture. Tracing what the library has meant since its beginning, examining how its significance has shifted, and pondering its importance in the twenty-first century, notable contributors—including the Librarian of Congress and the former executive director of the HathiTrust—present a cultural history of the library. In an informative introduction, Alice Crawford sets out the book's purpose and scope, and an international array of scholars, librarians, writers, and critics offer vivid perspectives about the library through their chosen fields. The Meaning of the Library will appeal to all who are interested in this vital institution's heritage and ongoing legacy.
Michel Foucault remains one of the towering intellectual figures of the last half century. Michel Foucault's works on sexuality, madness, the prison and medicine are classics and his example continues to challenge and inspire. The philosopher gave public lectures at the College de France from 1971 until his death in 1984 - these lectures were seminal events and created benchmarks for contemporary critical inquiry. in modern criminal justice and its method of categorizing individuals who resemble their crime before they commit it. Michel Foucault shows how and why defining abnormality and normality were prerogatives of power in the 19th century and shaped the institutions. thought and offer a unique window into his way of thinking.
Critique of Modernity
For over two hundred years, the notion of modernity has dominated Western social thought. Yet as we approach the end of the millenium, we find the concept under seige: constantly being challenged, rejected or refined. In Critique of Modernity d, Alain Touraine, one of our leading social thinkers, offers an outstanding analysis and reinterpretation of the modern for the twenty-first century.
This 25th anniversary edition of Steven Levy's classic book traces the exploits of the computer revolution's original hackers -- those brilliant and eccentric nerds from the late 1950s through the early '80s who took risks, bent the rules, and pushed the world in a radical new direction. With updated material from noteworthy hackers such as Bill Gates, Mark Zuckerberg, Richard Stallman, and Steve Wozniak, Hackers is a fascinating story that begins in early computer research labs and leads to the first home computers. Levy profiles the imaginative brainiacs who found clever and unorthodox solutions to computer engineering problems. They had a shared sense of values, known as "the hacker ethic," that still thrives today. Hackers captures a seminal period in recent history when underground activities blazed a trail for today's digital world, from MIT students finagling access to clunky computer-card machines to the DIY culture that spawned the Altair and the Apple II.
