Par Hubert Guillaud le 24/02/11 | 4 commentaires | 2,638 lectures | Impression Kevin Slavin est le cofondateur d’ Area/Code devenu il y a peu Zynga , un studio de conception de jeux. Et c’est pour ce travail qu’il est surtout connu (voir ses interventions en 2009 à Picnic dont nous vous avions rendu compte ici et là ), mais c’est à une tout autre exploration – oh combien passionnante, bien que particulièrement alambiquée – à laquelle il nous a conviée à la conférence Lift qui se tenait récemment à Genève. Image : Kevin Slavin sur la scène de Lift11, photographié par Ivo Näpflin . Sa présentation s’appuyait sur une précédente présentation faite il y a 4 ans qui portait sur le bas Manhattan, le quartier financier de New York, et qui s’interrogeait pour comprendre comment les villes pouvaient apprendre à écouter le pouls de la ville.

When algorithms control the world
Algorithms are spreading their influence around the globe In reality, our electronic overlords are already taking control, and they are doing it in a far more subtle way than science fiction would have us believe. Their weapon of choice - the algorithm. Behind every smart web service is some even smarter web code.
Why web personalisation could skew objectivity
Information we see online is increasingly being tailored by filtered, personalised searches on search engines, automated recommendations from online bookstores and social networks whose algorithms only tell us what is happening to those friends we care about the most. The information society can be as diverse as it likes but each of us is already cosseted within our own familiar, safe, predictable information cocoon, so online campaigner Eli Pariser argues in his new book The Filter Bubble. Along with Evgeny Morozov, author of The Net Delusion, Eli Pariser joins Gareth Mitchell to debate the pros and cons of web personalisation.His team at the Neural Systems Laboratory, University of Washington, hopes to take brain-computer interface (BCI) technology to the next level by attempting to teach robots new skills directly via brain signals. Robotic surrogates that offer paralyzed people the freedom to explore their environment, manipulate objects or simply fetch things has been the holy grail of BCI research for a long time. Dr Rao's team began by programming a humanoid robot with simple behaviours which users could then select with a wearable electroencephalogram (EEG) cap that picked up their brain activity. The brain generates what is known as a P300, or P3, signal involuntarily, each time it recognizes an object. This signal is caused by millions of neurons firing together in a synchronised fashion.
The robot that reads your mind to train itself
Click listeners shared their search results through the show's Facebook page. How personalised is the web? That's the question that Click listeners all over the world have been helping us answer. The worry is that we are cosseted in an information cocoon based on personalised results from search engines, automated recommendations from online bookstores and social networks that feed us gossip and news only from our innermost circle of friends.
Click listeners test 'filter bubble'
This week, Hewlett-Packard (where I am on the board) announced that it is exploring jettisoning its struggling PC business in favor of investing more heavily in software, where it sees better potential for growth. Meanwhile, Google plans to buy up the cellphone handset maker Motorola Mobility. Both moves surprised the tech world. But both moves are also in line with a trend I've observed, one that makes me optimistic about the future growth of the American and world economies, despite the recent turmoil in the stock market. In short, software is eating the world.
