Oldest Bird Was Actually a Dinosaur - For 150 years, Archaeopteryx held the "world's oldest known bird" record, but scientists now believe this animal was a dinosaur. - A new, small dinosaur from China shares traits with Archaeopteryxand likely evolved from it. - Many dinosaurs experimented with flight and feathers, but only some evolved into birds and survived extinction. Archaeopteryx, widely regarded as being the world's oldest known bird, has just been knocked off its scientific perch, since new research concludes this feathered animal was, in fact, a dinosaur. The study, published in the latest issue of the journal Nature, falls on the 150th anniversary of Archaeopteryx's discovery. With Archaeopteryx likely removed from the bird family tree, a few other prehistoric species now become the world's oldest known birds.

Facebook is watching you Des études mentionnées dans The Guardian Weekly en mars 2009 suggèrent qu’un quart des habitants du Royaume-Uni souffrent d’une forme de paranoïa. L’accroissement de la maladie aurait quelque chose à voir avec les effets conjugués de l’urbanisation, de la mondialisation, des migrations, des médias et de la disparité des richesses. La logique voudrait par conséquent que la proportion de ceux qui parmi nous souffrent de paranoïa augmente à mesure que nous nous dirigeons vers une forme complexe de surveillance, rendue possible par l’utilisation généralisée des « réseaux sociaux » comme Facebook. Et, ainsi que nos propres recherches en Suède et d’autres études le montrent, nous sommes nombreux à prendre part à ce nouveau genre de contrôle sur une base volontaire, souvent sans être conscients de son ampleur. Prenons l’exemple d’Adam’s Block, un site qui diffusait de la vidéo en direct du carrefour des rues Ellis et Taylor à San Francisco, dans un but de simple divertissement.
tech Sean Parker at the Web 2.0 Summit yesterday (photo by JD Lasica) Sean Parker, CEOs of Salesforce & eBay highlight day 1 of Web 2.0 Summit The one conference I try to make every year is the venerable Web 2.0 Summit in San Francisco. Here are some highlights from day one of the three-day conference, which you can follow live on Livestream. Highlights of Web 2.0 Summit 2011 Sean Parker, who was immortalized on screen by Justin Timberlake as a brilliant, rich party boy in “The Social Network,” was captivating when questioned by host John Battelle: • On Facebook: “The problem isn’t privacy but the glut of information available to power users” who prop up the network. • There was an interesting exchange when Mashable co-editor Ben Parr asked Parker about his Wikipedia entry, which says: “Sources are inconsistent as to whether he was a co-founder or early employee of Napster.” • Would it kill Wikipedia to include photo credits for photos of living individuals?
Technology The same image data drives both RGB stripe and PenTile RGBW™ displays. However, conventional RGB stripe displays render (draw) images by assigning a color and luminance (brightness) to an entire RGB-triplet as a whole pixel, adjusting its three RGB subpixels to set a single addressable point. Images on a PenTile RGBW™ panel are subpixel rendered, meaning they are drawn at the subpixel level (the individual points of light), rather than to the whole pixels of an RGB stripe display. Subpixel rendering dramatically increases addressability and enables the sophisticated image processing used in PenTile RGBW™ displays.
How To Block Facebook's Face Recognition And Tighten Other Privacy Settings Facebook seems to be forever pushing the boundaries of what "online privacy" means. Today we see the latest iteration of this--Face Recognition. By adjusting its interface, Facebook has now enabled "tag suggestions" to many more of its users around the world, which means your friends will get an alert if someone uploads a photo that Facebook thinks contains your image. Face Recognition Under the "Account" drop-down menu at the top-right of Facebook's title bar, click "Privacy settings." Easy, wasn't it? While you're there on the privacy page, check a few other things too: Things you share Check this list, which starts with "Posts by me" and ends with "Places you check in to" and verify that the status is "Friends only," which is as tight as you can set these (although you can customize the settings to prevent particular friends from accessing each of the shred items on a granular level). Things others share Contact information This may be one that you'd most like to protect. Block lists
Charge Your Cell Phone with Your Voice South Korean researchers developed a new technique for turning sound into electricity, allowing a mobile phones to be charged while the user is talking over the phone. At the Sungkyunkwan University in Seoul, Dr. Sang-Woo Kim is working on a revolutionary new technology that he hopes will change the way we use our cell phones in the future. So far one type of untapped energy source which has been overlooked according to Dr. We live in a noisy environment: cars, trains, airplanes all produce almost constant noise. Dr.
FRIDA Robot will Make your Gadget Meet FRIDA – a two handed concept robot for industrial assembly applications. This striking creation might be able to bridge the gap between fully manual assembly and fully automated manufacturing lines. The Frida project was started back in 2007 with a core team of Swiss researchers from ABB team that was then complemented by other teams from Sweden, Norway, Germany, the United States and China. The prototypes were manufactured and assembled in Sweden but many students from different universities around the world were also involved in different stages of the development. FRIDA was created in order to meet changing scenarios frequently encountered in the consumer electronics industry and other sectors. FRIDA come as dual-arms which are integrated into the torso of the unit. Key technology features: Currently several prototypes have left the lab and are being tested in pilot applications, with more work required to reach a fully agile assembly scenario.
Annotated.js For large, complex Javascript applications or libraries, Annotated.js provides a language extension for expressing the structure & validity of your code. By annotating your regular Javascript code, the Annotated.js runtime provides additional language features like declarative namespaces, class and module macros, and runtime type testing. Runs directly in the browser, even in external sources - what you see in the IDE is what you get in your browser's debug session. Annotated.js is legal javascript and runs natively in the browser without eval, code rewriting or server-side compilation - it's also fully compatible with popular minifiers, parallel or AJAX-y script loaders, code optimiziers, etc. Usage Install Though feature complete, Annotated.js has not yet reached a stable release, so you will need to check out the source from github: Download Annotated.js annotated(function() { // Your Annotated Javascript code goes here ... Modules & Classes That's it! Mixins // You can alias mixins, too!
