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)

America s Deadliest Export
'A fireball of terse information.'Oliver Stone 'A remarkable collection. Blum concentrates on matters of great current significance, and does not pull his punches. They land, backed with evidence and acute analysis.'Noam Chomsky For over sixty-five years, the United States war machine has been on automatic pilot. Since World War II we have been conditioned to believe that America's motives in 'exporting' democracy are honorable, even noble. In this startling and provocative book, William Blum, a leading dissident chronicler of US foreign policy and the author of controversial bestseller Rogue State, argues that nothing could be further from the truth. Moreover, unless this fallacy is unlearned, and until people understand fully the worldwide suffering American policy has caused, we will never be able to stop the monster.
Pep’s wife, Cristina Serra, told me, ‘I think Pep shares too much in your book. Too much tactical information. He’s very open about these things in his press conferences too. Other coaches don’t do that. Any coach who reads your book will get a complete run down of Pep’s tactics . . .’ For three extraordinary seasons, Martí Perarnau was given total access around Bayern Munich – to its players, its backroom staff, its board members and, above all, to its manager, Pep Guardiola. In the follow-up to his critically acclaimed account of Guardiola’s first full season at Bayern, Pep Confidential, Perarnau now lifts the lid on the Catalan’s whole tenure in Bavaria. Pep Guardiola: The Evolution takes the reader on a journey through three action packed seasons as Bayern smashed domestic records yet struggled to emulate that dominance in Europe, analysing Guardiola’s management style through key moments on and off the field. As the author shadows the manager and his superstar players during training and matchdays, he delivers a portrait of some of football’s most spellbinding individuals that is as enthralling as it is utterly unique. Perarnau reveals how Guardiola improved as a manager at Bayern despite failing to land the ultimate prize in European football, examines his decision to leave Germany to take up the challenge at Manchester City and how his managerial style will continue to evolve in the Premier League. This is more than the story of three seasons with one of the biggest clubs in the game, it is a portrait and analysis of a manager and the footballing philosophies that have beguiled the world.
The Democratic Surround
We commonly think of the psychedelic sixties as an explosion of creative energy and freedom that arose in direct revolt against the social restraint and authoritarian hierarchy of the early Cold War years. Yet, as Fred Turner reveals in The Democratic Surround, the decades that brought us the Korean War and communist witch hunts also witnessed an extraordinary turn toward explicitly democratic, open, and inclusive ideas of communication and with them new, flexible models of social order. Surprisingly, he shows that it was this turn that brought us the revolutionary multimedia and wild-eyed individualism of the 1960s counterculture. In this prequel to his celebrated book From Counterculture to Cyberculture, Turner rewrites the history of postwar America, showing how in the 1940s and ’50s American liberalism offered a far more radical social vision than we now remember. Turner tracks the influential mid-century entwining of Bauhaus aesthetics with American social science and psychology. From the Museum of Modern Art in New York to the New Bauhaus in Chicago and Black Mountain College in North Carolina, Turner shows how some of the most well-known artists and intellectuals of the forties developed new models of media, new theories of interpersonal and international collaboration, and new visions of an open, tolerant, and democratic self in direct contrast to the repression and conformity associated with the fascist and communist movements. He then shows how their work shaped some of the most significant media events of the Cold War, including Edward Steichen’s Family of Man exhibition, the multimedia performances of John Cage, and, ultimately, the psychedelic Be-Ins of the sixties. Turner demonstrates that by the end of the 1950s this vision of the democratic self and the media built to promote it would actually become part of the mainstream, even shaping American propaganda efforts in Europe. Overturning common misconceptions of these transformational years, The Democratic Surround shows just how much the artistic and social radicalism of the sixties owed to the liberal ideals of Cold War America, a democratic vision that still underlies our hopes for digital media today.
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.
