Why we programmed a robot to act like a sheepdog
Have you watched a sheepdog gather sheep on a hillside? The sheep move in waves and pulse back and forth, the dog weaving behind and around them. Squint a bit and it’s like watching iron filings on a piece of paper being drawn around by a magnet underneath, or a flock of starlings darting from an approaching falcon, or a school of fish evading an oncoming penguin. The patterns look similar between each event because the coordinated behaviour we see in sheep flocks or fish schools – where individuals are all closely packed and aligned in a certain direction – can reduce their chances of being identified or eaten by predators. What we found supported the long-standing assertion that individual animals respond to potential danger by moving towards the centre of a fleeing group – a theory called the “selfish herd” that was first proposed by the great evolutionary biologist Bill Hamilton in the 1970s. Dog rules We found that the dog appeared to be using two very simple rules. Robot shepherds

Revue des deux mondes – Votre livre, co-écrit avec Bertrand Naivin, fait le constat d’une désillusion. Pauline Escande-Gauquié – La culture hacker, web, a été escortée par une idéologie très forte, celle de l’accessibilité gratuite pour tous au savoir et à la connaissance. Revue des deux mondes – Il s’agit notamment d’une désillusion parce que l’autre visage des réseaux sociaux dont vous parlez dans ce livre est celui d’un monstre. Pauline Escande-Gauquié – Avec mon co-auteur, nous soulignons que le monstre, sur l’espace social, a toujours eu une fonction d’alerte, d’avertissement. Les réseaux sociaux sont un medium, c’est-à-dire une technique. (Photo : Pexels)

IBM’s machine argues, pretty convincingly, with humans
Media playback is unsupported on your device On a stage in San Francisco, IBM’s Project Debater spoke, listened and rebutted a human’s arguments in what was described as a groundbreaking display of artificial intelligence. The machine drew from a library of “hundreds of millions” of documents - mostly newspaper articles and academic journals - to form its responses to a topic it was not prepared for beforehand. Its performance was not without slip-ups, but those in attendance made clear their thoughts when voting on who did best. While the humans had better delivery, the group agreed, the machine offered greater substance in its arguments. That, IBM said, spoke to the heart of its goal: augmenting human beings to make decisions quickly and with more data than ever before. “I think it says actually very optimistic things about how humans respond to facts and figures,” said Noa Ovadia, one of the human debaters at the event. Offline thinking Project Debater was not hooked up to the internet.
Malcolm Lowry
Clarence Malcolm Lowry (/ˈlaʊri/; 28 July 1909 – 26 June 1957) was an English poet and novelist who is best known for his 1947 novel Under the Volcano, which was voted No. 11 in the Modern Library 100 Best Novels list.[2] Biography[edit] Early years in England[edit] Lowry was born in New Brighton, Wirral, UK[3] the fourth son of Evelyn Boden and Arthur Lowry, a cotton broker with roots in Cumberland. He was educated at The Leys School in Cambridge [4] (the school made famous by the novel Goodbye, Mr. In autumn 1929 he enrolled at Cambridge to placate his parents. The twin obsessions which would dominate his life, alcohol and literature, were firmly in place. After Cambridge, Lowry lived briefly in London, existing on the fringes of the vibrant Thirties literary scene and meeting Dylan Thomas, among others.

"Synthetic human" CGI demonstrates eerie photorealism generated in real-time
On Wednesday morning at the Game Developers Conference in San Francisco, Epic Games unveiled a remarkable demonstration of its latest real-time digital rendering system called Unreal Engine. The demonstration showed a completely digital copy of actor Andy Serkis reciting lines from Macbeth illustrating the incredibly rapid evolution of photorealistic digital effects. Back in 2016 Rogue One: A Star Wars Story delivered up a completely photo-realistic, computer-generated Peter Cushing, reprising his role from the original 1977 Star Wars. The latest state-of-the-art demonstration of illustrating where we are it with photorealistic digital characters comes through a combination of new technology from several different companies, blending volumetric capture advances with a new real-time rendering system. The result is full uncanny valley stuff, with an amazing depth of detail that replicates micro-muscular contractions on the actor's face in startling lifelike detail. View gallery - 3 images
David Graeber : « La plupart des gens trouvent leur travail complètement inutile »
Anthropologue et militant anarchiste, David Graeber fut la figure de proue du mouvement Occupy Wall Street. Inventeur du terme « bullshit jobs », ses recherches portent sur le travail, la valeur, la dette. A l’invitation du Collège de France, il a récemment présenté en France ses derniers travaux sur ceux qu’il considère comme les nouveaux prolétaires : les travailleurs du soin, ceux qui composent la « caring class ». Rediffusion d’été On retrouve David Graeber dans les salons de la Fondation Hugo, qui accueille les professeurs étrangers invités au Collège de France. Il vient d’arriver de Londres, où il enseigne à la London School of Economics depuis que Yale s’est séparé de lui, et qu’il n’a pu trouver d’autre poste dans une université américaine. Votre conférence au Collège de France, le 22 mars, était intitulée Utilité et inutilité du travail sous titrée The Revolt of the caring classes. Raphaël Bourgois Journaliste, Rédacteur en chef d'AOC
Low-cost USB Rubber Ducky pen-test tool for $3 using Digispark and Duck2Spark
It’s a story as old as time: some hacker sees nice hardware pen-testing tool, hacker recoils in horror at the price of said tool, hacker builds their own version for a fraction of the price. An example of this is Rubber Ducky, an excellent Hak5 hacking tool that thanks to the work of several developers we can emulate using a small and cheap Digispark. An advantage of cheap hardware from generic off the shelf parts is that it is disposable and almost impossible to trace. The USB Rubber Ducky is a keystroke injection tool disguised as a generic flash drive. Computers recognize it as a regular keyboard and automatically accept its pre-programmed keystroke payloads at over 1000 words per minute. But at $45 plus shipping Rubber Ducky is not exactly a cheap tool, fortunately we can DIY a clone for only $3 with a Digispark development board and some free software. Step 1: Setup Digispark Development Environment Before starting to work with our board, we must have installed the Arduino IDE.
