mattnyc99 writes "Earlier this summer we followed a war robot contest in England. But now, after the Russian onslaught in Georgia, this weekend's TechX Challenge in Singapore takes on a bigger meaning: can small countries keep up with military superpowers by upmodding existing robots for their own needs and then arming them? Researchers in the Far East seem to be struggling with their A.I. research right now, but this could just be the beginning of the 'little guys' fighting back. From the article: 'Chan says the agency wants to use more locally developed robots to help in homeland security and counterterrorist operations. The DSTA's goal is to improve robotic artificial intelligence so it can build machines to perform dangerous tasks — reconnaissance, surveillance and the handling of hazardous materials — that American robots already can. ... Back at Nanyang Technological University, Michael Lau acknowledges the urgency of the research but says the AI for urban warfare just isn't ready. "We don't really believe fully autonomous robots are possible yet," says the Evolution team supervisor. "How does a robot differentiate between friend and foe?"'" We've discussed similar projects from DARPA in the past. Reader coondoggie notes that enthusiasts will be able to participate in the lighter side of robot warfare next month in Texas.

Bennett Haselton contributes the following essay on the consequences of license choice as it applies to sites based on user contributions; read on below for more of his big idea for making Knol a more useful resource. "Google Knol should allow its writers to publish under a Creative Commons Share Alike license. The preceding sentence may not mean much to you, but if you've ever wanted to cite a Wikipedia article as a source, or simply read a Wikipedia article with some assurance that someone wasn't pulling your leg with some creative editing, or if you've wanted to contribute to Wikipedia but couldn't afford the time unless you received some modest compensation for it, then the addition of this one simple feature to Knol might make all the difference."

DeviceGuru writes "Stanford University will soon begin offering a series of 10 free, online computer science and electrical engineering courses. Initial courses will provide an introduction to computer science and an introduction to field of robotics, among other topics. The courses, offered under the auspices of Stanford Engineering Everywhere (SEE), are nearly identical to standard courses offered to registered Stanford students and will comprise downloadable video lectures, handouts, assignments, exams, and transcripts. And get this: all the courses' materials are being released under the Attribution-Noncommercial-Share Alike 3.0 Unported license."

Hugh Pickens writes "Researchers at the University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick graphene for storing electrical charge in ultracapacitors. They believe their development shows promise that graphene could eventually double the capacity of existing ultracapacitors. 'Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power,' says one of the researchers. Two main methods exist to store electrical energy: in rechargeable batteries and in ultracapacitors, which are becoming increasingly commercialized but are not yet well known to the public. Some advantages of ultracapacitors over traditional energy storage devices such as batteries include: higher power capability, longer life, a wider thermal operating range, lighter, more flexible packaging and lower maintenance. Graphene has a surface area of 2,630 square meters, almost the area of a football field, per gram of material."

An anonymous reader writes "After having my university degrees, a couple of IT certifications, and over ten years of work experience in the industry, with 2-4 years of verifiable employment with each employer, working with a wide range of technologies, is it reasonable to ask me to take some test on a job interview? The same companies don't ask other professionals (lawyer, accountant, sales, HR, etc.) to submit to any kind of in-house tests when they are hired. Why are IT professionals treated differently and in such a paternalistic way? More importantly, why do IT professionals accept being treated less favorably than members of other professions? Should IT professionals start to refuse to be treated as not real professionals?"

Toren Altair recommends a story up on the Space Fellowship site that begins "NASA's Phoenix Mars Lander has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander. The Surface Stereo Imager ... caught a dust devil in action west of the lander in four frames shot about 50 seconds apart from each other. 'It was a surprise to have a dust devil so visible that it stood [out] with just the normal processing we do,' said Mark Lemmon of Texas A&M University, College Station, lead scientist for the stereo camera. 'Once we saw a couple that way, we did some additional processing and found there are dust devils in 12 of the images.'"

An anonymous reader tips us to news that researchers at University of California, Berkeley, have successfully test driven a 60-foot bus that controlled its own steering. Sensors on the bus detected magnets that had been embedded in a San Leandro road, and it was able to reach stops within one centimeter of its desired position. Acceleration and braking during the test were controlled by a human operator, but the system is capable of handling those as well, and has done so on test courses. "... sensors mounted under the bus measured the magnetic fields created from the roadway magnets, which were placed beneath the pavement surface 1 meter apart along the center of the lane. The information was translated into the bus's lateral and longitudinal position by an on-board computer, which then directed the vehicle to move accordingly. For a vehicle traveling 60 miles per hour, data from 27 meters (88 feet) of roadway can be read and processed in 1 second. Zhang added that the system is robust enough to withstand a wide range of operating conditions, including rain or snow, a significant improvement to other vehicle guidance systems based upon optics."

aqui writes "A university student at Carleton is learning that no good deed goes unpunished. After hacking into what was probably a not-so-secure university network, this guy took the time to write a 16-page paper on his methods and sent it to the system admins. Sounds like White Hat behavior to me. Yes, he should have asked permission before trying, but throwing the book at the guy and wrecking his life with criminal charges (which stick for a long time) seems a little excessive. The university should spend money on hiring some admins with better computer skills and teaching skills rather than paying lawyers. In the Engineering department at my old university, the unofficial policy was that when you broke in, didn't damage anything, and reported the problem and how you broke in, they didn't charge you (if you maliciously caused damage, you usually faced academic sanctions). In some cases, the students were hired or they 'volunteered' for the summer to help secure the servers or fix the hole they found. The result was that Engineering ended up with one of the most secure systems in the university." Read on for the rest of aqui's comments.

Iddo Genuth writes "Scientists from Penn State University are designing the future of refrigerators and other cooling devices through magnetic field refrigeration. The investigation pertaining to electrically induced heat effects of some ferroelectric polymers might one day replace electrically powered refrigerators and their compressors and coils. The researchers are focusing on ferroelectric polymers that exhibit temperature changes at room temperature under an electrical field. The same technology might also find its way into computers and other devices in the future, making them run cooler without complex cooling mechanisms."

Starting in November, Queen's University Belfast will offer a course that will use the psychology of the Star Wars Jedi Knights to teach students communication skills and personal development. The university's publicity material reads 'the course "Feel the Force: How to Train in the Jedi Way" teaches the "real-life psychological techniques behind Jedi mind tricks"' and promises to explore 'wider issues behind the Star Wars universe, like balance, destiny, dualism, fatherhood and fascism.' The course is very affordable but the droid fees are outrageous.
