Twitter Mood Predicts The Stock Market
There’s no shortage of people who say they know how to predict whether the stock market will go up or down on a particular day. But there are few, if any, who can do it consistently better than tossing a coin. For many economists that’s easy to explain. Conventional economic theory holds that the movement of prices in a perfect market should follow a random walk and should be impossible to predict with an accuracy greater than 50 per cent. There’s a fly in this economic ointment, however. Numerous studies show that stock market prices are not random and this implies that they ought to be predictable.
Un immeuble confortable et anonyme, au cœur de Washington, à quelques rues de la Maison Blanche . Dans une enfilade de bureaux au fond du 5 e étage, une vingtaine de jeunes gens, surtout des garçons, travaillent discrètement, dans une ambiance à la fois studieuse et décontractée. Cette petite équipe, composée d'informaticiens, de juristes et de sociologues, est en train de réaliser l'utopie suprême des hackers et des militants libertaires du monde entier : un logiciel permettant la création de réseaux sans fil à haut débit 100 % autonomes, qui fonctionneront sur les fréquences Wi-Fi, sans s' appuyer sur aucune infrastructure existante – ni relais téléphonique, ni câble, ni satellite.

Zeiss Cinemizer OLED with head-tracking hands-on (video)
The Carl Zeiss Cinemizer OLED has been a long time in the making -- we first heard about the video glasses at Macworld in 2008 -- but the company has yet to push the head-mounted display past the prototype phase. We stumbled upon Zeiss' booth here at CeBIT, where we found a version of the glasses that look mighty similar to the mock-up we saw in marketing materials from 2010 , but are now equipped with a pair of head-tracking modules to expand the yet-to-be released marvel's practicality. With head-tracking now on board, the Cinemizer can theoretically appeal to gamers, architects, even educators, who can use the glasses in the classroom.
LED Lights Make Augmented Vision a Reality | Elemental LEDucation
Okay, this is just freaky. We know LED lights are versatile enough to be used for practically anything, but LED contact lenses? Really?! Yes, as it turns out, really. University of Washington researchers have figured out how to implant semitransparent red and blue LED lights in contact lenses, for the purpose of receiving and displaying data in sharp visual images and video.
'SixthSense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. We've evolved over millions of years to sense the world around us. When we encounter something, someone or some place, we use our five natural senses to perceive information about it; that information helps us make decisions and chose the right actions to take.

Intelligence ambiante
It’s about time: By the end of 2012, Google will launch a pair of Android-powered, augmented reality, head-up display (HUD) glasses. Anonymous Google employees, speaking to The New York Times, say that the glasses will resemble a pair of Oakley Thumps (pictured above), will have 3G or 4G connectivity, a forward-facing camera, GPS, and a full array of movement sensors. They will cost “around the price of current smartphones.”

Internet Traffic is now 51% Non-Human
So you thought the Internet was made by and for people? Think again. A study by Incapsula , a provider of cloud-based security for web sites (mind you where this data comes from), concludes that 51% of all Internet traffic is generated by non-human sources such as hacking software, scrapers and automated spam mechanisms. While 20% of the 51% non-human traffic is’ good’, the 31% majority of this non-human traffic is potentially malicious. The study is based on data collected from 1,000 websites that utilize Incapsula’s services, and it determined that just 49% of Web traffic is human browsing. 20% is benign non-human search engine traffic, but 31% of all Internet traffic is tied to malicious activities. 19% is from ” ‘spies’ collecting competitive intelligence,” 5% is from automated hacking tools seeking out vulnerabilities, 5% is from scrapers and 2% is from content spammers.Par Hubert Guillaud le 23/06/09 | 8 commentaires | 5,161 lectures | Impression L’une des thématiques de cette première édition de Lift with Fing se consacrait à l’avenir des objets, ces objets intelligents proposant des fonctions, des formes d’interactions et de communications nouvelles. Un internet des objets, comme le décrit Daniel Kaplan , délégué général de la Fing , qui ambitionne de transformer notre rapport au monde aussi profondément que l’internet d’aujourd’hui a transformé notre quotidien.
L’internet des objets va-t-il changer la nature des objets
Posted by venessa miemis on Monday, June 20, 2011 · 18 Comments There is a growing movement towards peer-to-peer value exchange and production, prompted by a variety of things, like economic conditions, shifting cultural values, exploration into collective intelligence, and further enabled by social technologies. I’ve been tracking the online marketplaces that have been cropping up for sharing, swapping, gifting and renting, as well as sites that give people different kinds of opportunity to share skills and knowledge, innovate, and work collaboratively both on and offline.
