This Robot Makes Its Own Custom Tools Out of Glue At this point, you’ve probably noticed the similarities between this process and 3D printing, which is much faster and provides a lot more detail. The reason this robot can’t just 3D print a cup is that the thermoplastic materials don’t provide any good ways of bonding objects to the robot itself, which would mean that the robot would have complex manipulators and deal with grasping, and the whole point (or part of the point) of the HMA is to make complicated things like that unnecessary. While the actual execution of this task was performed autonomously by the robot, the planning was not, since the robot doesn’t yet have a perception process (or perception hardware, for that matter). This is something that the researchers will be working on in the future, and they fantasize about a robot that can adaptively extend its body how and when it deems fit. They also suggest that this technique could be used to create robots that can autonomously repair themselves, autonomously increase their own size and functionality, and even autonomously construct other robots out of movable HMA parts and integrated motors, all of which sounds like a surefire recipe for disaster if we’ve ever heard one.

Very interesting! From the Wiki: http://en.wikipedia.org/wiki/Braess%27s_paradox The paradox is stated as follows: “For each point of a road network, let there be given the number of cars starting from it, and the destination of the cars. Under these conditions one wishes to estimate the distribution of traffic flow. Whether one street is preferable to another depends not only on the quality of the road, but also on the density of the flow. If every driver takes the path that looks most favorable to him, the resultant running times need not be minimal. Furthermore, it is indicated by an example that an extension of the road network may cause a redistribution of the traffic that results in longer individual running times.” The reason for this is that in a Nash equilibrium, drivers have no incentive to change their routes. If the system is not in a Nash equilibrium, selfish drivers must be able to improve their respective travel times by changing the routes they take. In the case of Braess’s paradox, drivers will continue to switch until they reach Nash equilibrium, despite the reduction in overall performance.

Digital Politics My most recent #attentioneconomy is difficult, and several people have asked for a clear summary or introduction to motivate the time and effort required to slog through it. So I built a slideshow to present the argument. It isn’t short and it isn’t much easier than the essay, but I put a lot of effort into the presentation so I hope it helps! If you appreciate the work, please participate! You can see the full presentation here: http://digitalinterface.blogspot.com/2012/05/digital-politics.html The essay on which this slideshow is based can be found here: http://digitalinterface.blogspot.com/2012/05/attention-economy-11-systems-of.html My blog has links to all my work on the attention economy, and links for further research. I’d love to hear any thoughts you have!

Amira notes originally shared this post: The Self Illusion: How the Brain Creates Identity “John Locke, the philosopher, who also argued that personal identity was really dependent on the autobiographical or episodic memories, and you are the sum of your memories, which, of course, is something that fractionates and fragments in various forms of dementia. (…) As we all know, memory is notoriously fallible. It’s not cast in stone. It’s not something that is stable. It’s constantly reshaping itself. So the fact that we have a multitude of unconscious processes which are generating this coherence of consciousness, which is the I experience, and the truth that our memories are very selective and ultimately corruptible, we tend to remember things which fit with our general characterization of what our self is. We tend to ignore all the information that is inconsistent. We have all these attribution biases. We have cognitive dissonance. The very thing psychology keeps telling us, that we have all these unconscious mechanisms that reframe information, to fit with a coherent story, then both the “I” and the “me”, to all intents and purposes, are generated narratives. The illusions I talk about often are this sense that there is an integrated individual, with a veridical notion of past. And there’s nothing at the center. We’re the product of the emergent property, I would argue, of the multitude of these processes that generate us. (…) The irrational superstitious behaviors : what I think religions do is they capitalize on a lot of inclinations that children have. Then I entered into a series of work, and my particular interest was this idea of essentialism and sacred objects and moral contamination. (…) If you put people through stressful situations or you overload it, you can see the reemergence of these kinds of […]

In addition, previously reported chronometric cues to deception were replicated in this study, with significantly longer response latencies when lying than when telling the truth. moreover, as far as we are aware, this study is the first to provide evidence that the capacity to detect lies and the ability to deceive others are associated. this finding suggests the existence of a “deception-general” ability that may influence both “sides” of deceptive interactions. open for discussion. “You can’t kid a kidder”: association between production and detection of deception in an interactive deception task full article. “You can’t kid a kidder”: association between production and detection of deception in an interactive deception task Both the ability to deceive others, and the ability to detect deception, has long been proposed to confer an evolutionary advantage.

Derya Unutmaz originally shared this post: A group of American researchers from MIT, Indiana University, and Tufts University, led by Erin Treacy Solovey, have developed Brainput — pronounced brain-put, not bra-input — a system that can detect when your brain is trying to multitask, and offload some of that workload to a computer. The idea of using computers to do our grunt work isn’t exactly new — without them, the internet wouldn’t exist, manufacturing would be a very different beast, and we’d all have to get a lot better at mental arithmetic. I would say that the development of cheap, general purpose computers over the last 50 years, and the freedoms they have granted us, is one of mankind’s most important advancements. Brainput is something else entirely though. Using functional near-infrared spectroscopy (fNIRS), which is basically a portable, poor man’s version of fMRI, Brainput measures the activity of your brain. This data is analyzed, and if Brainput detects that you’re multitasking, the software kicks in and helps you out. In the case of the Brainput research paper, Solovey and her team set up a maze with two remotely controlled robots. The operator, equipped with fNIRS headgear, has to navigate both robots through the maze simultaneously, constantly switching back and forth between them. When Brainput detects that the driver is multitasking, it tells the robots to use their own sensors to help with navigation. Overall, with Brainput turned on, operator performance improved — and yet they didn’t generally notice that the robots were partially autonomous.

Why Men Do Not Revolt “Gamer and many others who study the nature of colonial rule offer the best insights into the functioning of our corporate state. We have been, like nations on the periphery of empire, colonized. We are controlled by tiny corporate entities that have no loyalty to the nation and indeed in the language of traditional patriotism are traitors. They strip us of our resources, keep us politically passive and enrich themselves at our expense. The mechanisms of control are familiar to those whom the Martinique-born French psychiatrist and writer Frantz Fanon called “the wretched of the earth,” including African-Americans. The colonized are denied job security. Incomes are reduced to subsistence level. The poor are plunged into desperation. Mass movements, such as labor unions, are dismantled. The school system is degraded so only the elites have access to a superior education. Laws are written to legalize corporate plunder and abuse, as well as criminalize dissent. And the ensuing fear and instability—keenly felt this past weekend by the more than 200,000 Americans who lost their unemployment benefits—ensure political passivity by diverting all personal energy toward survival. It is an old, old game. “A change of power does not require the election of a Mitt Romney or a Barack Obama or a Democratic majority in Congress, or an attempt to reform the system or electing progressive candidates, but rather a destruction of corporate domination of the political process—Gamer’s “patron-client” networks. It requires the establishment of new mechanisms of governance to distribute wealth and protect resources, to curtail corporate power, to cope with the destruction of the ecosystem and to foster the common good. But we must first recognize ourselves as colonial subjects. We must accept that we have no effective voice in the way we are governed. We must […]
