Edward Snowden, Julian Assange, and Chelsea Manning are key figures in the struggles playing out in our democracies over internet use, state secrets, and mass surveillance in the age of terror. When not decried as traitors, they are seen as whistleblowers whose crucial revelations are meant to denounce a problem or correct an injustice. Yet, for Geoffroy de Lagasnerie, they are much more than that. Snowden, Assange, and Manning are exemplars who have reinvented an art of revolt. Consciously or no, they have inaugurated a new form of political action and a new identity for the political subject. Anonymity as practiced by WikiLeaks and the flight and requests for asylum of Snowden and Assange break with traditional forms of democratic protest. Yet we can hardly dismiss them as acts of cowardice. Rather, as Lagasnerie suggests, such solitary choices challenge us to question classic modes of collective action, calling old conceptions of the state and citizenship into question and inviting us to reformulate the language of critical philosophy. In the process, he pays homage to the actions and lives of these three figures.

Smartphone users have come to expect high-quality apps. This has increased the importance of software testing in mobile software development. Unfortunately, testing apps—particularly the GUI—can be very time-consuming. Exercising every user interface element and verifying transitions between different views of the app under test quickly becomes problematic. For example, execution of iOS GUI test suites using Apple’s UI Automation framework can take an hour or more if the app’s interface is complicated. The longer it takes to run a test, the less frequently the test can be run, which in turn reduces software quality.
This book describes how to accelerate the testing process for iOS apps using HadoopUnit, a distributed test execution environment that leverages the parallelism inherent in the Hadoop platform. HadoopUnit was previously used to run unit and system tests in the cloud. It has been modified to perform GUI testing of iOS apps on a small-scale cluster—a modest computing infrastructure available to almost every developer.

The Raspberry Pi NoIR Camera Module is a custom designed add-on for Raspberry Pi that does not have an 'IR cut filter' installed. Like the regular Pi camera, it attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data. Raspberry Pi NOT INCLUDED The board itself is tiny, at around 25mm x 20mm x 9mm. It also weighs just over 3g, making it perfect for mobile or other applications where size and weight are important. It connects to Raspberry Pi by way of a short ribbon cable. The camera is connected to the BCM2835 processor on the Pi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi. The sensor itself has a native resolution of 5 megapixel, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video. This version is best for night-vision use – you'll have to flood the area you're shooting with infrared light. There is some nature photography that is enhanced by an IR camera, as well. It's not great for every-day video and photo taking. In those cases, we suggest the regular Pi Cam. A small piece of blue filter plastic is included in case you want to re-add the cut filter, however it wont look as good as if you had the camera with the original filter in place so it's more for experimentation! The camera is supported in the latest version of Raspbian, Raspberry Pi's preferred operating system.

In this revealing insider’s look at the US intelligence community’s efforts to fight the insurgency in Iraq, author Steven K. O’Hern, who served in Iraq in 2005 as a senior intelligence officer, offers a critical assessment of our intelligence failures and suggests ways of improving our ability to fight an often elusive enemy.
O’Hern criticizes America’s military leaders for being enamored with high-technology solutions for all situations, including intelligence operations. Essentially, we are still relying on an intelligence system that was designed to beat the Soviet army. Using examples from human source operations conducted in Iraq, this book explains why human intelligence—not technology—is the key to defeating an insurgency and why the US is so poor at using what the military calls "HUMINT." O’Hern also cites internal structural problems that work against effective intelligence operations. The author gives examples of missed opportunities that resulted from information being caught in "stovepipes" and red tape.
