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. The question is how to do it consistently. Today, Johan Bollen at Indiana University and a couple of pals say they’ve found just such a predictor buried in the seemingly mindless stream of words that emanates from the Twitterverse. For some time now, researchers have attempted to extract useful information from this firehose. Either way, this work is bound to attract interest. Commotion, le projet d'un Internet hors de tout contrôle. GENI. Outernet | Information for the World from Outer Space. The future of the open Internet is decentralized. The Internet is having a quarter-life crisis. At just 25 years old, it suffers from two serious problems: Surveillance is carried out en masse, and citizens in many countries can access only the heavily censored or propagandized information available to them.

Those woes have led to a growing chorus calling to decentralize the Internet—to take the power of the Web away from powerful corporations and governments and put it back in the hands of users. This movement toward a decentralized Internet—to a truly free space, where anyone can communicate privately with anyone else without censorship—does not originate from the White House, Pentagon, or the halls of the United Nations. Instead, as has so often been the case with Internet evolutions, groups of hackers, technologists, and idealists are tucked away in the cracks and shadows, slaving away to make this dream a reality. "In their own right, those farmers are the new Internet platform," says Irvine. Next comes what are called protocols. 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.

Un article de Wikipédia, l'encyclopédie libre. Pranav Mistry Compléments Pranav Mistry est un chercheur (ingénieur, inventeur et designer) né en 1981 à Palanpur, dans le nord du Gujarat en Inde. Il vit et travaille aujourd'hui aux États-Unis où il finit un doctorat et travaille actuellement en tant qu'assistant de recherche et doctorant au Media lab du MIT. Domaines d'étude[modifier | modifier le code] Pranav Mistry s'est spécialisé en informatique ubiquitaire et dans certaines approches transdisciplinaires de l'informatique. Il s'est surtout fait connaitre[2],[3] pour une invention (ordinateur et interface dématérialisés) dite « SixthSense » ("6ème sens" en français), parfois aussi dénommée WUW (pour « Wear Ur World » [4]).

Philosophie[modifier | modifier le code] À la fois intéressé par le design, l'art, l'architecture, la technologie et la psychologie ou le Web sémantique, il explique sur sa page personnelle[5] qu'il « aime voir la technologie du point de vue design et vice-versa »". LED Lights Make Augmented Vision a Reality | Elemental LEDucation. LED Lights Make Augmented Vision a Reality 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. Once miniature green LEDs are developed (and they’re in the works, as of now), full color displays will be possible. Lead researcher Babak Parvis comments “You won’t necessarily have to shift your focus to see the image generated by the contact lens,” it would just appear in front of you and your view of the real world will be completely unobstructed when the display is turned off. Ah, the real world. Thanks to Extreme Tech for the quote and Trendhunter for the images.

LiFi Consortium. SixthSense - a wearable gestural interface (MIT Media Lab) '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. But arguably the most useful information that can help us make the right decision is not naturally perceivable with our five senses, namely the data, information and knowledge that mankind has accumulated about everything and which is increasingly all available online. Although the miniaturization of computing devices allows us to carry computers in our pockets, keeping us continually connected to the digital world, there is no link between our digital devices and our interactions with the physical world. . . . some more pictures are coming soon.

SixthSense. Un article de Wikipédia, l'encyclopédie libre. Projet en cours de développement en 1998[1] L'invention s'appelle "aremac"[2]. Le projet SixthSense (« sixième sens »), parfois dénommé WUW pour Wear ur world, est un projet d'ordinateur ubiquitaire et dématérialisé. Ce projet est en cours de développement au MIT par Steve Mann, Pranav Mistry et Pattie Maes au MIT Media Lab et a été présenté en 2001[2]. Il s'agit d'un système logiciel et d'interfaces permettant de transformer des objets de l'environnement quotidien en des éléments d'un ordinateur semi-dématérialisé, qu'on emporte avec soi ; de nombreux objets deviennent supports possibles d'information ou d'interaction.

The Evolution Will Be Socialized. From the actions of the Egyptian government to the policies of Facebook, the monopolies of central banks to the corporatization of the Internet, we are witnessing the potential of a peer-to-peer networking become overshadowed by the hierarchies of the status quo. It’s time for us to gather and see what is still possible on the net, and what, if anything, can be built to replace it. I have had a vague misgiving about the direction the net’s been going for, well, maybe 15 years. But until recently, it was more like the feeling when another Starbucks opens on the block, a Wal-Mart moves into town, or a bank forecloses unnecessarily on that cool local bookstore to make room for another bank. Lately, however, what’s wrong with the net has become quite crystalized for me.

It started with the corporate-government banishment of Wikileaks last year, and reached a peak with Egypt shutting off its networks to stave off revolution. I received literally thousands of emails in response. HTML5. Un article de Wikipédia, l'encyclopédie libre. HTML5 (HyperText Markup Language 5) est la dernière révision majeure d'HTML (format de données conçu pour représenter les pages web). Cette version est en développement en 2013. HTML5 spécifie deux syntaxes d'un modèle abstrait défini en termes de DOM : HTML5 et XHTML5. Le langage comprend également une couche application avec de nombreuses API, ainsi qu'un algorithme afin de pouvoir traiter les documents à la syntaxe non conforme. Le travail a été repris par le W3C en mars 2007 après avoir été lancé par le WHATWG. Les deux organisations travaillent en parallèle sur le même document afin de maintenir une version unique de la technologie.

Le W3C vise la clôture des ajouts de fonctionnalités le 22 mai 2011 et une finalisation de la spécification en 2014[1], et encourage les développeurs Web à utiliser HTML 5 dès maintenant.

L'évolution des ordinateurs : la course à la miniaturisation et à la diffusion dans le milieu ambiant L'intelligence ambiante est ce que pourrait devenir l'informatique dans la première moitié du XXIe siècle en repoussant les limites technologiques qu'elle avait à la fin du XXe siècle [réf. nécessaire].

Ce concept semble pouvoir tenir lieu de traduction non littérale aux concepts nés en Amérique du Nord sous le vocable initial d'informatique ubiquitaire, systèmes pervasifs ou encore ordinateur évanescent [réf. nécessaire]. Dans cette approche, le concept même de système d’information ou d'ordinateur change : d’une activité de traitement exclusivement centrée sur l’utilisateur, l'informatique devient interface entre objets communicants et personnes, et entre personnes [réf. nécessaire].

Facteurs en jeu[modifier | modifier le code] Vers une informatique diffuse[modifier | modifier le code] Perspectives économiques[modifier | modifier le code] The Future Is All About Context: The Pragmatic Web. The semantic Web has long been heralded as the future of the Web. Proponents have said that Web experiences will some day become more meaningful and relevant based on the AI-esque computational power of natural-language processing (NLP) and structured data that is understandable by machines for interpretation. However, with the rise of the social Web, we see that what truly makes our online experiences meaningful is not necessarily the Web's ability to approximate human language or to return search results with syntactical exactness.

The value of the semantic Web will take time because the intelligent personal agents that are able to process this structured data still have a long way to go before becoming fully actualized. This guest post was written by Alisa Leonard-Hansen. Rather, meaningful and relevant experiences now are born out of the context of our identities and social graph: the pragmatics, or contextual meaning, of our online identities. Android-powered Google Glasses: The augmented reality HUD dream is coming. 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.” Unlike Google’s upcoming home entertainment system, a pair of wearable Google Glasses makes an awful lot of sense.

Google’s arsenal of real-time, mobile, location-aware services is second to none; Search, Latitude, Goggles(!) Let’s take a look at what life with a pair of Googgles would be like. You wake up, shower, and put on your Google specs. In short, Google could finally kick start the wearable computer dream. As utopian as this sounds, though, it’s important to ground Google’s AR glasses in reality. Informatique ubiquitaire. Un article de Wikipédia, l'encyclopédie libre. L'évolution des ordinateurs : la course à la minaturisation et à la diffusion dans le milieu ambiant[1]. L´informatique ubiquitaire est la troisième ère de l'histoire de l'informatique, qui succède à l'ère des ordinateurs personnels et celle des mainframe.

Dans cette ère l'utilisateur a à sa disposition une gamme de petits appareils informatiques tels que smartphone ou assistant personnel, et leur utilisation fait partie de l'ordinaire de sa vie quotidienne. Ces appareils rendent l'accès à l'information facile pour tout le monde, n'importe où et n'importe quand.

Les utilisateurs ont alors la possibilité de s'échanger des données facilement, rapidement et sans effort, quel que soit leur position géographique[2]. Cette omniprésence de l'accès à l'information a un fort impact sur la société, modifie les habitudes de travail et de vie privée[2]. Caractéristiques[modifier | modifier le code] Histoire[modifier | modifier le code] 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. Presumably these numbers will only rise. Anthrophomorphobia ahoy! Thanks Bruce. L’internet des objets va-t-il changer la nature des objets.
