writes with news of an interesting experiment spatial input device. From the article: "The mouse is a hugely useful device but it is also a two-dimensional one. But what of the three-dimensional world and the long-standing, but growing, promise of virtual reality. What kind of device will take the place of the mouse when we begin to interact in three-dimensions? Anh Nguyen and Amy Banic ... have created an intelligent thimble that can sense its position accurately in three-dimensions and respond to a set of pre-programmed gestures that allow the user to interact with objects in a virtual three-dimensional world. ... The result is the 3DTouch, a thimble-like device that sits on the end of a finger, equipped with a 3D accelerometer, a 3D magnetometer, and 3D gyroscope. That allows the data from each sensor to be compared and combined to produce a far more precise estimate of orientation than a single measurement alone. In addition, the 3DTouch has an optical flow sensor that measures the movement of the device against a two-dimensional surface, exactly like that inside an ordinary mouse."
The prototype is wired up to an Arduino Uno, with a program on the host machine polling the device and converting the data into input events. A video of it in action is below the fold, a pre-print of the research paper
is on arxiv, and a series of weblog entries explain some of the development

writes The KDE Community is proud to announce the release of KDE Frameworks 5.0. Frameworks 5 is the next generation of KDE libraries, modularized and optimized for easy integration in Qt applications. The Frameworks offer a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. There are over 50 different Frameworks as part of this release providing solutions including hardware integration, file format support, additional widgets, plotting functions, spell checking and more. Many of the Frameworks are cross platform and have minimal or no extra dependencies making them easy to build and add to any Qt application.
Version five of the desktop shell, Plasma, will be released soon
, and packages of Plasma-next and KDE Frameworks 5 will trickle into Ubuntu Utopic over the next few days

An anonymous reader writes Jeffrey Baldwin was essentially starved to death by his grandparents. Funds had been raised to build a monument for Jeffrey in Toronto. The monument was designed to feature Jeffrey in a Superman costume, and even though Superman should be public domain, DC Comics has denied the request. "The request to DC had been made by Todd Boyce, an Ottawa father who did not know the Baldwin family. Boyce was so moved by the testimony at the coroner’s inquest into Jeffrey’s death last year that he started an online fundraising campaign for the monument. DC’s senior vice-president of business and legal affairs, Amy Genkins, told Boyce in an email that 'for a variety of legal reasons, we are not able to accede to the request, nor many other incredibly worthy projects that come to our attention.'... For Boyce, it was a huge blow, as he felt the Superman aspect was a crucial part of the bronze monument, which will include a bench. The coroner’s inquest heard from Jeffrey’s father that his son loved to dress up as Superman."Read Replies (1)

writes There is a not so fine line between data dashboards and other information displays that provide pretty but otherwise useless and unactionable information; and those that provide effective answers to key questions. Data-Driven Security: Analysis, Visualization and Dashboards is all about the later. In this extremely valuable book, authors Jay Jacobs and Bob Rudis show you how to find security patterns in your data logs and extract enough information from it to create effective information security countermeasures. By using data correctly and truly understanding what that data means, the authors show how you can achieve much greater levels of security.
