RESHARED POST FROM VINEET KEWALRAMANI

Vineet KewalRamani originally shared this post: Already surrounded by machines that allow him, painstakingly, to communicate, the physicist Stephen Hawking last summer donned what looked like a rakish black headband that held a feather-light device the size of a small matchbox. Called the iBrain, this simple-looking contraption is part of an experiment that aims to allow Dr. Hawking — long paralyzed by amyotrophic lateral sclerosis, or Lou Gehrig’s disease — to communicate by merely thinking. iBrain, a Device That Can Read Thoughts NeuroVigil’s iBrain may help people with A.L.S., like Stephen Hawking, communicate using advanced machine-brain interfaces.

RESHARED POST FROM JOHN KELLDEN

This is a very interesting article, I’m not quite sure what to make of it. The quote +John Kellden cites below is worth reading, but I’m not sure what “Kantian wholes” Kaufmann is referring to. Is he talking about selves? Is this an explicitly panpsychist position hidden behind a veil of holism? Not that I’d object… The quote I’ll pick is below. “Life keeps making room for itself!” I’ll just note that this is true of the niches humans create too, of course. Not just our economies in the financial sense meant in this article, but for the literal environments that our bodies and its supporting infrastructure creates. And not the biological niches either, the ones filled by raccoon and your pet cat, or the bacteria in your gut. We create, along with these biological cohabitants, any number of technological devices, objects, highly industrially designed to play any number of niche roles in ones daily life. These objects, which are as (and usually more) resource-intensive as any living creature, is also part of the life we continue to make room for. The very part of us that makes us human is the part of us that is making ourselves digital. “This niche creation via the expanding Adjacent Possible expands Darwin’s wedge filled floor with ever more wedges! Life keeps making more room for itself! Competition tempers this expansion. More, I think that, on average, each new species, alone or with others, creates more than one new empty Adjacent Possible niche, generating a self amplifying, “supracritical” explosion of ever new species occupying the ever new niches they create without selection. The biopshere explodes in interwoven diversity. This explosion process is interrupted by small and large extinction events.” John Kellden originally shared this post: Insights, part 26: Beyond Adjacent Possible “…new niches […]

RESHARED POST FROM MARK HAHNEL

Copying +Billy Hung‘s comment as well, since it bears repeating: I am also sad to see that Koch didn’t get tenure. However, what I find most admirable about this is that Koch went into this following his own priority of educating and mentoring students. He was clear that he would be evaluated on a different standard, but chose to do what his heart told him is the right thing. This is a form of civil disobedience against the academia, and I think he deserves a great amount of credit for it. As with most schools, the tenure process is one that has rules and guidelines. In fact, most schools could possibly use more detailed guidelines to make it less a guess-what-we-want process. It is sad that UNM couldn’t fit Koch’s work into the existing guidelines, but I think the criticism here should be on their inability to adjust these guidelines to take into account newer forms of scholarship, and not on the fact that they followed existing guidelines.

FF: SO NOW YOU HAD AN ABSURDLY POWERFUL…

FF: So now you had an absurdly powerful chess playing system. What does one do with it? Playing against humans would not be sensible, and even other computers would be simply killed by it. VR: That was not the point, not my intention. I have been using it for purely analytical purposes, to try to solve certain openings. What does “to solve” in this context mean? And how do you go about it. We developed an algorithm which attempts to classify chess positions into wins, draws and losses. Using this algorithm, we have just finished classifying the King’s Gambit. In other words, the King’s Gambit is now solved. http://www.chessbase.com/newsdetail.asp?newsid=8047 ChessBase.com – Chess News – Rajlich: Busting the King’s Gambit, this time for sure Publisher of high quality chess programs and databases.

AND CURIOUSLY, AND INTERESTINGLY, IT LOOKS…

And curiously, and interestingly, it looks as though at any time about half the ants in the colony are just doing nothing. So, despite what it says in the Bible, about, you know, “Look to the ant, thou sluggard,” in fact, you could think of those ants as reserves. That is to say, if something happened — and I’ve never seen anything like this happen, but I’ve only been looking for 20 years — if something happened, they might all come out if they were needed. But in fact, mostly they’re just hanging around in there. And I think it’s a very interesting question — what is there about the way the colony is organized that might give some function to a reserve of ants who are doing nothing? And they sort of stand as a buffer in between the ants working deep inside the nest and the ants working outside. And if you mark ants that are working outside, and dig up a colony, you never see them deep down. So what’s happening is that the ants work inside the nest when they’re younger. They somehow get into this reserve. And then eventually they get recruited to join this exterior workforce. And once they belong to the ants that work outside, they never go back down. http://www.ted.com/talks/deborah_gordon_digs_ants.html #attentioneconomy #selforganization #mythoflazy Deborah Gordon digs ants | Video on TED.com TED Talks With a dusty backhoe, a handful of Japanese paint markers and a few students in tow, Deborah Gordon digs up ant colonies in the Arizona desert in search of keys to understanding complex syst…

RESHARED POST FROM REBECCA MACKINNON

What happened to society because we made a lot of little boy scouts? We produced generations of campers. We distributed enough skills, knowledge, interest, and appreciation of camping among the public that interest in camping sustains itself. +Mark Surman says we need a new scouting movement that will prepare our kids for the world they’ll be living in. We need a scouting movement for coding the web. He’s exactly right. Not just about the need for coders. This is how we should be thinking about skills-based learning generally. Not just in terms of the brain in front of us (though that matters a lot!) but also about the networks that brain will be part of in the future. The whole talk is brilliant. Rebecca MacKinnon originally shared this post: A scouting movement for the web I’ve been thinking about ‘a scouting movement for the web’ for a while: a practical movement focused on the skills and creativity that spring from the internet. I finally got around to doing a talk on this idea at last week’s TEDx Seneca. Here is a video of the talk: You do not have sufficient freedom levels to view this video.

RESHARED POST FROM BRUNO GONÇALVES

However, it is still unclear about the attention dynamics of the vast majority of topics and stories that never reach the critical mass. As such, it has remained an open question about the attention dynamics and the initial growth of these items. We attempt to propose dynamics of the user attention, measured in the number of user comments, for these general items on social media websites. #attentioneconomy Bruno Gonçalves originally shared this post: From User Comments to On-line Conversations. (arXiv:1204.0128v1 [cs.CY]) We present an analysis of user conversations in on-line social media and their evolution over time. We propose a dynamic model that accurately predicts the growth dynamics and structural properties of conversation threads. The model successfully reconciles the differing observations that have been reported in existing studies. By separating artificial factors from user behaviors, we show that there are actually underlying rules in common for on-line conversations in different social media web…

URBAN CHALLENGE

Area A DARPA‘s Urban Grand Challenge ran over the weekend, with CMU/GM taking first place, and Stanford/VW taking second. This situation was exactly reversed for the 2005 Grand Challenge, which means the rivalry between Stanford and Carnegie Mellon is building to epic proportions. More info here and here. I’ve been following this challenge for a few years now, using the Nova special on the 2005 race for my classes. The big change for this race involves the car responding to other agents in its environment, including other moving cars (driven by professional stunt drivers), and for obeying all traffic laws, including right-of-way laws at intersections. I went to a couple of the site visits and the first thing (one of) the vehicles did for me was a three-way turn. Now, imagine you’re watching this vehicle all by itself do a three-way turn and then come to an intersection, and there was a car there already and when it pulled up, another car pulled up after it. It knew enough to wait for the first car to go because by the rules, it knew that car had precedent. But it also knew that it had precedence over the other car that showed up after. It was stunning. … I mean it was spooky because they went down the road, they made a turn. And he turned to me and he said, ‘Now look, there’s nobody inside there right?’ I said, ‘No, no, there’s nobody inside there.’ He said, ‘Now, and there’s nobody controlling them remotely right’ because it looked like they were being driven by somebody. Now these were the two vehicles that got the furthest, by the way. |link| There remains the critical problem that the robots are still treating other drivers merely as moving objects, and not as full-bodied […]

I AM JUST KIDDING€”ALTHOUGH THE FACTS I STATE ARE EMPIRICALLY TRUE.

From A robot performs standup comedy to a lackluster response by Michael Drucker in McSweeney’s I was made in a factory. The funny setup is that robots make new robots. You, as a human, are probably thinking, “I would love to spend all day making more humans because the sexual experience is pleasurable to my flesh.” However, the point of irony is that robots make new robots—but we do not have sex. We use lasers and molten metal. Am I right?

TAKING CARE

The researchers measured the bond between the children and the robot in several ways. Firstly, as with other toddlers, they touched QRIO mostly on the arms and hands, rather than on the face or legs. For this age group, “the amount of touching is a good predictor of how you are doing as a social being”, Movellan says. The children also treated QRIO with more care and attention than a similar-looking but inanimate robot that the researchers called Robby, which acted as a control in the experiment. Once they had grown accustomed to QRIO, they hugged it much more than Robby, who also received far more rough treatment. A panel, who watched videos of the interactions between the children and QRIO, concluded that these interactions increased in quality over several months. Eventually, the children seemed to care about the robot’s well being. They helped it up when it fell, and played “care-taking” games with it – most commonly, when QRIO’s batteries ran out of juice and it lay down, a toddler would come up and cover it with a blanket and say “night, night”. Altering QRIO’s behaviour also changed the children’s attitude towards the robot. When the researchers programmed QRIO to spend all its time dancing, the kids quickly lost interest. When the robot went back to its old self, the kids again treated it like a peer again. |link via|

A BETTER PLANT

Researchers successfully simulate photosynthesis and design a better leaf University of Illinois researchers have built a better plant, one that produces more leaves and fruit without needing extra fertilizer. The researchers accomplished the feat using a computer model that mimics the process of evolution. Theirs is the first model to simulate every step of the photosynthetic process. … “The question we wanted to ask, was, ‘Can we do better than the plant, in terms of productivity?’ ” It wasn’t feasible to tackle this question with experiments on actual plants, Long said. With more than 100 proteins involved in photosynthesis, testing one protein at a time would require an enormous investment of time and money. “But now that we have the photosynthetic process ‘in silico,’ we can test all possible permutations on the supercomputer,” he said.

A COMPUTER WILL START THE TASK

Paralysed man’s mind is ‘read’ Electrodes have been implanted in the brain of Eric Ramsay, who has been “locked in” – conscious but paralysed – since a car crash eight years ago. These have been recording pulses in areas of the brain involved in speech. Now, New Scientist magazine reports, they are to use the signals he generates to drive speech software. Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay’s brain is imagining some 80% of the time. In the next few weeks, a computer will start the task of translating his thoughts into sounds. Thanks Steve
