DARPA Working On Arthur C. Clarke Weapon Idea 453

holy_calamity writes "DARPA is working on a weapon which is similar to one first described by Arthur C. Clarke in his 1955 novel Earthlight — firing jets of molten metal using strong electromagnetic fields. The Magneto Hydrodynamic Explosive Munition (MAHEM) will function on a smaller scale than Clarke's fictional blaster. DARPA's write-up says it could be 'packaged into a missile, projectile or other platform and delivered close to target for final engagement and kill.' Clarke is also widely credited with suggesting geostationary communications satellites — what other ideas of his will come to pass?"

Next-Generation CAPTCHA Exploits the Semantic Gap 327

captcha_fun writes "Researchers at Penn State have developed a patent-pending image-based CAPTCHA technology for next-generation computer authentication. A user is asked to pass two tests: (1) click the geometric center of an image within a composite image, and (2) annotate an image using a word selected from a list. These images shown to the users have fake colors, textures, and edges, based on a sequence of randomly-generated parameters. Computer vision and recognition algorithms, such as alipr, rely on original colors, textures, and shapes in order to interpret the semantic content of an image. Because of the endowed power of imagination, even without the correct color, texture, and shape information, humans can still pass the tests with ease. Until computers can 'imagine' what is missing from an image, robotic programs will be unable to pass these tests. The system is called IMAGINATION and you can try it out." This sounds promising given how broken current CAPTCHA technology is.

German Wikipedia To Be Published As a Book 184

David Gerard writes "Bertelsmann is to publish a single-volume book of the German Wikipedia in cooperation with Wikimedia Deutschland. It will cost 20 Euros, and 1 Euro from each copy will go to Wikimedia. They're editing down the most popular 50,000 articles for the 1,000-page book, to be released in September. Because of the open-source origin of the material, the publisher cannot claim copyright in the book." The German-language Wikipedia is second in size only to the English version, which has 2.3 million articles.

An IM Patent for the iPhone? 71

Ian Lamont writes "Apple has filed a patent for IM on portable devices, which could mean that it's getting ready to launch an IM client for the iPhone. The filing is titled 'Portable Electronic Device for Instant Messaging', and covers methods for sending, receiving, and viewing ongoing conversations. The proposed GUI is similar to Apple's current interface for SMS. As for why iChat wasn't enabled for the iPhone earlier, there's some interesting background and analysis here, which also includes a discussion of AIM for the iPhone. IM also came up in the discussions last year about the most-wanted features in iPhone 2.0."

iGoogle Launches Developer Sandbox 62

gurubaba writes "Google has announced the launch of iGoogle Developer Sandbox, which will allow developers to build and test applications. The Sandbox provides support for building social applications using the OpenSocial API. 'The iGoogle OpenSocial container will allow developers to build full page applications, just like the ones on Facebook, using the Canvas View. The applications built using the developer Sandbox can display profile information, post activity updates, send messages and gadget invites and add friends. The developers will also be able to monetize the applications through ads.'"
