John Snodgrass writes "Neil Hunt, Chief Product Officer at Netflix, has announced on the Netflix Prize Forums that they are planning to hold a new data mining competition. The second competition will have some twists and is expected to be shorter in duration. It will feature two grand prizes, to be awarded in a 6 and 18 month time frame. A previous competitor still active on the board has already dubbed it: 'The Sparse Matrix: Reordered' and 'The Sparse Matrix: Factorizations.'"

As the July 31st deadline for The Matrix Online's closure looms, Gamer Limit is running a story discussing the game's shortcomings, as well as some of the decisions that led to its failure. Quoting: "I honestly thought the writers must have absolutely hated the remaining cast of The Matrix Trilogy or something, because they constantly seemed to go out of their way to phase out existing characters in favor of newer ones. The cast overall basically made me, as a player, feel distant from the main storyline and made the entire game feel like a Matrix side story instead of the continuation it was meant to be. ... When MxO first launched there was an entire team dedicated to playing the game as Agents and other key characters as a means to further in-game events and directly interact with players, giving players the feeling that they truly were making a difference. After the SOE buyout of the game the LESIG team was reduced to playing minor characters before eventually being phased out and replaced with a Live Event Team (LET) comprised purely of volunteers."

Strudelkugel writes "The NY Times has an article about a conference during which the potential dangers of machine intelligence were discussed. 'Impressed and alarmed by advances in artificial intelligence, a group of computer scientists is debating whether there should be limits on research that might lead to loss of human control over computer-based systems that carry a growing share of society's workload, from waging war to chatting with customers on the phone. Their concern is that further advances could create profound social disruptions and even have dangerous consequences.' The money quote: 'Something new has taken place in the past five to eight years,' Dr. Horvitz said. 'Technologists are replacing religion, and their ideas are resonating in some ways with the same idea of the Rapture.'"

Smart grid technology is a hot issue on Capitol Hill, but some are raising questions about the idea. In recent days we've discussed the smart grid's potential exposure to worm attacks, consumers' unreadiness for the idea, and whether the whole concept may need a rethink. A Congressional hearing on Thursday surfaced another reason for caution: the smart grid's vulnerability to EMP. "Electromagnetic Pulse" refers to the damage caused in electrical circuits and systems when a nuclear explosive goes off nearby. The electric grid as it's currently constituted is vulnerable to EMP; the further down the road we go towards a smart grid, the more vulnerable it will become. "It makes a great equalizer for small nations looking to stand up to military Goliaths, argues Rep. Roscoe Bartlett (Rep.-Md.), a former research scientist and engineer who has worked in the past on projects for NASA and the military. All one needs to wreak some serious EMP damage, he charges, is a sea-worthy steamer, $100,000 to buy a scud-missile launcher, and a crude nuclear weapon. Then fling the device high into the air and detonate its warhead. Such a system might not paralyze the entire United States, he concedes. 'But you could shut down all of New England. And if you missed by 100 miles, it's as good as a bulls eye.'"

An Anonymous Reader writes "The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal. Japanese researchers have shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals."

GhostX9 writes "Tom's Hardware has a long interview with security expert Joanna Rutkowska (which is unfortunately split over 9 pages). Many think that kernel rootkits are the most dangerous attacks, but Joanna and her team have been studying exploits beyond Ring 0 for some years. Joanna is most well known for the BluePill virtualization attack (Ring -1) and in this interview she chats a little bit about Ring -2 and Ring -3 attacks that go beyond kernel rootkits. What's surprising is how robust the classic BluePill proof-of-concept is: 'Many people tried to prove that BluePill is "detectable" by writing various virtualization detectors (but not BluePill detectors). They simply assumed that if we detect a virtualization being used, this means that we are "under" BluePill. This assumption was made because there were no products using hardware virtualization a few years ago. Needless to say, if we followed this way of reasoning, we might similarly say that if an executable makes network connections, then it must surely be a botnet.'" Rutkowska says that for her own security, "I don't use any A/V product on any of my machines (including all the virtual machines). I don't see how an A/V program could offer any increased security over the quite-reasonable-setup I already deployed with the help of virtualization." She runs three separate virtual machines, designated Red, Yellow, and Green, each running a separate browser and used for increasingly sensitive tasks.

destinyland writes "Vint Cerf performed an hour-long Q&A at NASA for their 'Singularity University' (which is partially funded by Google ). A question about Twitter led Cerf to imagine even more useful micro-applications using the wireless internet and cell phones, including real-time health data and checking your location against a map of known biohazards and disease outbreaks. 'These systems have applications which I think we will discover over time,' Cerf says, adding 'For me, the exciting thing to just anticipate, are the new ideas for using these instruments.' Also speaking were Ray Kurzweil and nanotechnology expert Ray Merkle. (Read an interview with SU co-founder Peter Diamandis in the new issue of H+ magazine)."

Jon Morgan writes "Whilst heaving around numerous data storage systems to sell (they weigh A LOT!), we got to wondering: How heavy is a Petabyte of data storage? Our best guess is 365KG, which is 6 million times lighter than in 1980! But is there a lighter way to store a Petabyte?"

An anonymous reader writes "Researchers from ETH Zurich have recently managed to create an optical transistor from a single molecule in what is yet another important achievement on the road to quantum computing. The molecule itself is about 2 nanometers in size, much smaller than standard transistors, which means that a lot more could be integrated in a single chip. Dr. Hwang, lead author of the academic paper, said, 'Our single-molecule optical transistor generates almost negligible amount of heat. When a single molecule absorbs one photon, there is some probability (quantum yield) that the molecule emits a photon out. The rest of the energy absorbed turns into heat in the matrix. For the case of the specific hydrocarbon molecule that we use, the quantum yield is near 100%. So almost no heat is generated.'"

William Gibson's Neuromancer was first published 25 years ago. Dr_Ken writes with an excerpt from an article at MacWorld that delves into the current state of some of the technology that drives the book: "'Neuromancer is important because of its astounding predictive power. Gibson's core idea in the novel is the direct integration of man and computer, with all the possibilities (and horrors) that such a union entails. The book eventually sold more than 160 million copies, but bringing the book to popular attention took a long time and a lot of word-of-mouth. The sci-fi community, however, was acutely aware of the novel's importance when it came out: Neuromancer ran the table on sci-fi's big three awards in 1984, winning the Hugo Award, the Philip K. Dick Memorial Award, and the Nebula Award.'"

Designers James Auger and Jimmy Loizeau have created a clock that is powered by "eating" bugs. The clock traps insects on flypaper stretched across a roller system and then drops them into a vat of bacteria. The insects are then "digested" and the ensuing chemical reaction is transformed into power that keeps the rollers moving and the LCD clock working. The two offer another version that is powered by mice and an even cooler machine that picks insect fuel from spiderwebs with the help of a robotic arm and a video camera.

eldavojohn writes "Stanislaw Lem was arguably the greatest non-English science fiction writer before his death three years ago and left behind many science fiction novels with messages of satire and intrigue. The Futurological Congress is no different. The book has several motifs throughout it but I found the most prominent to be that we are living in an increasingly medicated society whereby the future may be wonderfully dystopian — in that the horrors of our existence are simply hidden by drugs on top of drugs on top of drugs. With a movie due out shortly by director Ari Folman, it seems like a good time to revisit this often overlooked short classic sci-fi work." Read on for the rest of eldavojohn's review

Yesterday, Sony Online Entertainment representative Daniel Myers announced that The Matrix Online will be shut down on July 31st. The game launched in 2005 after several delays and false starts, and shortly thereafter SOE bought the rights to operate the game from developer Monolith. Now, four years later, the game will join the ranks of closed MMOs. In a forum post, Myers said, "The team will also be whipping up an end-of-the-world event. It won't be quite the same as having over 100 developers in the game as Agents like when we ended beta, but we have 4 years of tricks up our sleeve. It'll be a chance to revisit all the things that make MxO the memorable experience it is. And how could we pull the plug without crushing everyone's RSI just one more time?"

Wired is running a story inspired by the level of gore in the recent Wolverine game that wonders: how much is too much? It mentions a study we discussed in February which indicated that violence tended to interest gamers less than other characteristics. "... the longer you play a 'twitch' action game, the less you notice the cultural content — the gushing blood, the shrieks of agony. You're too busy focusing on the gameplay. I noticed this with Wolverine. For the first hour, I found the deranged bloodshed both shocking and exciting; it made me feel like I 'was' Logan, the grunting, killing-machine character from Marvel Comics' X-Men universe. But as I became more expert, the cultural shell of the game boiled away. In a sort of staring-into-the-cascading-numbers-of-the-Matrix way, I found myself looking past the visible aspects of the game and savoring the underlying, invisible mechanics of play. ... The game became pure physics and algorithms: Vectors, speed and collision detection. The gore had become mostly irrelevant."

edadams sends in a story about the legal questions that are starting to crop up over property disputes in virtual worlds. A lawsuit in March 2008 that stopped one Second Life user from selling a virtual product created by another user marked the beginning of a significant amount of casework for several law firms, in large part due to the way Second Life's currency interacts closely with real money. (And yes, apparently the product in that particular case was for cybersex — did you have to ask?) "As transactions grow in volume, it's inevitable that disagreements will crop up. Linden says that although it will enforce its terms of service, including its ban on violating other users' intellectual property, it can't settle most disputes for users." A lawyer for one intellectual property firm handled a case in which the co-ownership of virtual real estate had to be determined, ending with a financial settlement given to two users who helped a virtual land developer run a group of Second Life islands. As virtual worlds get more popular and their business models more directly affect real-life finances, we can expect these legal issues to become more common as well.

lamaditx writes "The book Collective Intelligence in Action shows you how to apply theory from Machine Learning, Artificial Intelligence and Data Mining to your business. The goal is to create systems which make use of data created by groups of people — i.e. social networks — and abstract from these to gain new or additional information. Some of you might think "just another kind of Web 2.0." This is one application you might think of, but the input and output format do not matter that much. You can use these methods anywhere as long as the amount of data is big enough. You will find some examples related to the latest web technologies to explain methods, but the code is rather generic. Also, you won't find a lot disturbing details about HTML, HTTP and the like." Keep reading for the rest of Adrian's review.

An anonymous reader writes with news that IBM has filed a patent for "Bionic body armor" that would protect a wearer from long-range gunfire by detecting the incoming bullets and administering small shocks to the appropriate muscles required for moving out of the way. Quoting the patent: "When a marksman (such as a sniper) is attempting to fire a projectile from a firearm, the marksman typically prefers to be as far away from the target as possible, thus giving him or her a head start for the escape after the firing. As an example, the longest reported sniper hit was from a distance of about 2500 meters, resulting in a time of flight of about 4 seconds for the projectile/bullet. Had the target been aware of the inbound projectile, avoiding it by simply walking away would have been possible." After detecting the projectile, the armor would calculate the trajectory and "stimulate the target to move in a predefined manner ... sufficient to avoid any contact with the approaching projectile."

Al writes "Researchers at Georgia Tech have come up with the ideal way to test a new peizo-electric device that efficiently harvests power from bio-movement — attaching it to a hamster. The device contains a series of zinc-oxide nanowires mounted on top of a flexible plastic surface. As the plastic bends, the wires generate around a nanowatt of power. The Georgia Tech team, led by Zhong Lin Wang, wanted to show that their device could produce power from irregular movements so they attached it to a tiny hamster jacket. They also tried attaching it to a volunteer's finger. Here's a video of the hamster wearing his piezo-power outfit."

stoolpigeon writes "I vividly remember the first time I was able to dial up a BBS with my Commodore VIC-20. It was Star Trek themed, and I was excited to see that the Sysop was online. We typed a few lines of text back and forth while I hollered to everyone in the house that I was talking to someone through the computer. Things have come a long way since then, and I've put in quite a few hours experiencing one of the more exciting sides of the internet: participating in community. Of course it hasn't all been great. Communities on-line are just like any other, in that there are differences of opinion and issues that arise. Some are handled well, some are not. Social interaction can be very complicated, and learning how to manage a social site can be a process that involves a lot of painful lessons. Fortunately not all of our learning has to come through direct experience. Sometimes we have the opportunity to learn from the experience of others. Patrick O'Keefes book Managing Online Forums is that guide to the budding leader of the web's next great community. Keep reading for the rest of JR's review.

NIckGorton writes "Research is now underway in the US to seek FDA approval for an artificial liver. The Extracorporeal Liver Assist Device (ELAD) filters blood through a cartridge containing immortalized human liver cells with fiber tubes running through that allow the patients blood to interact with them. This allows the matrix of liver cells to perform both the metabolic (cleansing the blood of toxins/waste) and synthetic (producing albumin, clotting factors, etc) functions of the patient's failing liver. A small trial in China showed a statistically and clinically significant difference in 30 day survival with ELAD."
