twoblackeyes writes "PopSci delves into the 10 greatest technical challenges faced by game developers today, and the technology that will hopefully make them a thing of the past. At the top of every dev's wish list is increased realism: realisitic fire, water, enemy AI, material physics, etc. Here directly from the developers where the tech stands today, and where it will likely be tomorrow. '4. Artificial Intelligence - Problem: Once upon a time, the bad guys in videogames wandered around mindlessly, shooting at you while they waited to die. That doesn't cut it anymore. Players demand sophisticated enemies to fight and reliable in-game allies with which to fight them. Thing is, it's freaking complicated, and it eats up processor speed. "We're faking just enough smarts to make it work," says Mathieu Mazerole, lead engineer on Ubisoft's Assassin's Creed. Status: Imbuing characters in a game with lifelike decision-making ability involves employing the kind of high-level logic theories--learning decision trees, mobile navigation, finite-state machine models--used by top robotics engineers.'"

eldavojohn writes "A meteorite struck in Peru on Saturday leaving cinders, rock & water boiling out of the ground. Villagers nearby reported headaches & vomiting and attributed it to the event. From the article, 'Seven policemen who went to check on the reports also became ill and had to be given oxygen before being hospitalized, Lopez said. Rescue teams and experts were dispatched to the scene, where the meteorite left a 100-foot-wide (30-meter-wide) and 20-foot-deep (six-meter-deep) crater, said local official Marco Limache.' It's not yet clear whether this is from the meteorite, gas trapped underground that was released or a chemical reaction between the two."

cupofjoe writes "The Jet Propulsion Laboratory is reporting on the Cassini spacecraft's recent close flyby of the Saturnian moon Iapetus, highlighting images taken from distances 100 times closer than the Voyager 2 flyby in 1981. Near real-time images were shown to Cassini mission team members in a presentation at JPL yesterday, during which a pre-recorded message from Arthur C. Clarke was played to the audience. Clarke wished them luck on the flyby, reminding all present that he had included a pretty accurate description of Iapetus in the original 1968 text of "2001: A Space Odyssey", years before Voyager made its flyby."

Shipud writes "The National Science Foundation, Public Library of Science and the San Diego Supercomputing Center have partnered to set up what can best be described as a "YouTube for scientists", SciVee". Scientists can upload their research papers, accompanied by a video where they describe the work in the form of a short lecture, accompanied by a presentation. The formulaic, technical style of scientific writing, the heavy jargonization and the need for careful elaboration often renders reading papers a laborious effort. SciVee's creators hope that that the appeal of a video or audio explanation of paper will make it easier for others to more quickly grasp the concepts of a paper and make it more digestible both to colleagues and to the general public."

analogrithems writes "Recently I was asked by one of the suits in my company to come up with a method to comply with the new PCI DSS policy that requires companies to have write once, read many logs. In short the requirement is for a secure method to make sure that once a log is written it can never be deleted or changed. So far I've only been able to find commercial and hardware-based solutions. I would prefer to use an open source solution. I know this policy is already part of HIPPA and soon to be part of SOX. It seems like there ought to be a way to do this with cryptography and checksums to ensure authenticity. Has anyone seen or developed such a solution? Or how have you made compliance?"

An anonymous reader writes that earlier this month, Sony received word of a lawsuit from a Newport Beach company called Parallel Processing. They've filed against the electronics giant alleging that the Cell processor, used in the PlayStation 3, infringes on a patent they own. They've made the somewhat outrageous demand that every infringing chip (and console) be 'impounded and destroyed'. From the article at Next Generation: "The patent, 'Synchronized Parallel Processing with Shared Memory' was issued in October 1991. It describes a high-speed computer that breaks down a program 'into smaller concurrent processes running in different parallel processors' and resynchronizes the program for faster processing times ... Parallel Processing said that Sony's alleged actions have caused 'irreparable harm and monetary damage' to the company."

An anonymous reader writes "According to this report by IT PRO, scientists working at the University of California have discovered the main reason of hard drive failure. According to researchers, some materials used in hard drives are better at damping spin precession than others. Spin precession of magnetic material effects its neighbors' polarity and this can spread and cause sections of hard drives to spontaneously change polarity and lose data. This is known as a magnetic avalanche. So next time Windows fails to start, you'll know why!"

An anonymous reader writes "Looks like Matrox isn't as dead as some of us thought. This box of tricks lets you connect four displays up to a PC that's 250 meters away. All the graphic data is sent down a fiber optic cable to the Matrox box that then connects to the screens. To the end user it feels like they're working directly on the PC, but the PC can be locked away somewhere safe."

flyboy974 writes "Sony BMG Music Entertainment is suing the company that developed anti-piracy software for its CDs, claiming the technology was defective and cost the record company millions of dollars to settle consumer complaints and government investigations. The software in question is the MediaMax CD protection system, widely derided as a rootkit. Sony BMG is seeking to recover some $12 million in damages from the Phoenix-based technology company, according to court papers filed July 3."

posys writes "Wired Magazine has an article showing how the eternal patience of robots lends itself well to teaching new social skills to autistic children. 'The researchers hope that the end result is a human-like robot that can act as a "social mediator" for autistic children, a steppingstone to improved social interaction with other children and adults. "KASPAR provides autistic children with reliability and predictability. Since there are no surprises, they feel safe and secure," Robins said, adding that the purpose is not to replace human interaction and contact but to enhance it. Robins has already tested some imitation and turn-taking games with the children and his preliminary findings are positive.'"
