Who Are The Cypherpunks? This is the unauthorized telling of the revolutionary cryptography story behind the motion picture The Fifth Estate in theatres this October, and a penetrating look at the facts presented in We Steal Secrets: The Story of Wikileaks, a documentary out now. WikiLeaks brought to light a new form of whistleblowing, using powerful cryptographic code to hide leakers’ identities while they spill the private data of government agencies and corporations. But that technology has been evolving for decades in the hands of hackers and radical activists, from the libertarian enclaves of Northern California to Berlin to the Balkans. And the secret-killing machine continues to evolve beyond WikiLeaks, as a movement of hacktivists aims to obliterate the world’s institutional secrecy. Forbes journalist Andy Greenberg has traced its shadowy history from the cryptography revolution of the 1970s to Wikileaks founding hacker Julian Assange, Anonymous, and beyond. This is the story of the code and the characters?idealists, anarchists, extremists?who are transforming the next generation’s notion of what activism can be. With unrivaled access to such major players as Julian Assange, Daniel Domscheit-Berg, and WikiLeaks’ shadowy engineer known as the Architect, never before interviewed, Greenberg unveils the world of politically-motivated hackers?who they are and how they operate.

A world-famous security expert explores the social side of security In this thought-provoking volume, the bestselling author of Secrets & Lies and Beyond Fear examines security's essential role in making society possible. Every society has a dishonest minority who breaks rules and doesn't follow group norms. They're not just the selfish; they include people with different morals. Security is how we protect ourselves from this dishonest minority within and what enables us to trust strangers at the local, national, and global scale. This engaging and highly readable book explains why security will always exist, and why we're all better off if it isn't perfect. It covers: - Our evolved security systems and their unique role in facilitating and stabilizing human society. - How our deliberately created security systems support modern, complex societies. - Where security is breaking down, as computer and communication systems replace existing social systems, and as technology gives that dishonest minority more power. - The value of the dishonest minority, and how it serves as a catalyst for social change. Bruce Schneier is a world-famous security technologist, regularly consulted by media, business, and governments. Like Schneier's other highly successful books, Liars and Outliers offers profound insights into the complex issue of security as well as a riveting reading experience.

Its feature set equals or surpasses proprietary alternatives, allowing you to create location-aware queries and features with just a few lines of SQL code. PostGIS in Action is the first book devoted entirely to PostGIS. It will help both new and experienced users write spatial queries to solve real-world problems. For those with experience in more traditional relational databases, this book provides a background in vector-based GIS so you can quickly move to analyzing, viewing, and mapping data. Advanced users will learn how to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions suited specifically to their applications. It also discusses the new features available in PostgreSQL 8.4 and provides tutorials on using additional open source GIS tools in conjunction with PostGIS. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
