An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."

garg0yle writes "Police in San Diego were called to investigate an 11-year-old's science project, consisting of 'a motion detector made out of an empty Gatorade bottle and some electronics,' after the vice-principal came to the conclusion that it was a bomb. Charges aren't being laid against the youth, but it's being recommended that he and his family 'get counseling.' Apparently, the student violated school policies — I'm assuming these are policies against having any kind of independent thought?"

An anonymous reader writes "During several months of 2009, Moscow police looked at fake pictures displayed on their monitors instead of what was supposed to be video from the city surveillance cams. The subcontractor providing the cams was paid on the basis of 'the number of working cams,' so he delivered pre-cooked pictures stored on his servers. The camera company CEO has been arrested."

jmp_nyc writes "The developers at Turborilla have remade the 1983 classic game M.U.L.E. The game is free, and has slightly updated graphics, but more or less the same gameplay as the original version. As with the original game, up to four players can play against each other (or fewer than four with AI players taking the other spots). Unlike the original version, the four players can play against each other online. For those of you not familiar with M.U.L.E., it was one of the earliest economic simulation games, revolving around the colonization of the fictitious planet Irata (Atari spelled backwards). I have fond memories of spending what seemed like days at a time playing the game, as it's quite addictive, with the gameplay seeming simpler than it turns out to be. I'm sure I'm not the only Slashdotter who had a nasty M.U.L.E. addiction back in the day and would like a dose of nostalgia every now and then."

captainktainer writes "In one of the largest tests of EVE Online's new player sovereignty system in the Dominion expansion pack, a fleet of ships attempting to retake a lost star system was effectively annihilated amidst controversy. Defenders IT Alliance, a coalition succeeding the infamous Band of Brothers alliance (whose disbanding was covered in a previous story), effectively annihilated the enemy fleet, destroying thousands of dollars' worth of in-game assets. A representative of the alliance claimed to have destroyed a minimum of four, possibly five or more of the game's most expensive and powerful ship class, known as Titans. Both official and unofficial forums are filled with debate about whether the one-sided battle was due to difference in player skill or the well-known network failures after the release of the expansion. One of the attackers, a member of the GoonSwarm alliance, claims that because of bad coding, 'Only 5% of [the attackers] loaded,' meaning that lag prevented the attackers from using their ships, even as the defenders were able to destroy those ships unopposed. Even members of the victorious IT Alliance expressed disappointment at the outcome of the battle. CCP, EVE Online's publisher, has recently acknowledged poor network performance, especially in the advertised 'large fleet battles' that Dominion was supposed to encourage, and has asked players to help them stress test their code on Tuesday. Despite the admitted network failure, leaders of the attacking force do not expect CCP to replace lost ships, claiming that it was their own fault for not accounting for server failures. The incident raises questions about CCP's ability to cope with the increased network use associated with their rapid growth in subscriptions."

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."

A feature at Gamasutra examines one of the foundations of many MMORPGs — the idea that class roles within such a game fall into three basic categories: tank, healer, and damage dealer. The article evaluates the pros and cons of such an arrangement and takes a look at some alternatives. "Eliminating specialized roles means that we do away with boxing a class into a single role. Without Tanks, each class would have features that would help them participate in and survive many different encounters like heavy armor, strong avoidance, or some class or magical abilities that allow them to disengage from direct combat. Without specialized DPS, all classes should be able to do damage in order to defeat enemies. Some classes might specialize in damage type, like area of effect (AoE) damage; others might be able to exploit enemy weaknesses, and some might just be good at swinging a sharpened bit of metal in the right direction at a rapid rate. This design isn't just about having each class able to fill any trinity role. MMO combat would feel more dynamic in this system. Every player would have to react to combat events and defend against attacks."

Lucas123 writes "The Blu-ray Disc Association announced today that it has finalized the specification for Blu-ray 3-D discs. The market for 3-D, which includes 3-D enabled televisions, is expected to be $15.8 billion by 2015. Blu-ray 3-D will create a full 1080p resolution image for both eyes using MPEG4-MVC format. Even though two hi-def images are produced, the overhead is typically only 50% compared to equivalent 2D content. The spec also allows PS3 game consoles to play Blu-ray 3-D content. 'The specification also incorporates enhanced graphic features for 3D. These features provide a new experience for users, enabling navigation using 3D graphic menus and displaying 3D subtitles positioned in 3D video.'"

When an UK man was asked to be the best man at a friend's wedding he agreed that he would not pull any pranks before or during the ceremony. Now the groom wishes he had extended the agreement to after the blessed occasion as well. The best man snuck into the newlyweds' house while they were away on their honeymoon and placed a pressure-sensitive device under their mattress. The device now automatically tweets when the couple have sex. The updates include the length of activity and how vigorous the act was on a scale of 1-10.

dnaumov writes "FreeNAS, a popular, free NAS solution, is moving away from using FreeBSD as its underlying core OS and switching to Debian Linux. Version 0.8 of FreeNAS as well as all further releases are going to be based on Linux, while the FreeBSD-based 0.7 branch of FreeNAS is going into maintenance-only mode, according to main developer Volker Theile. A discussion about the switch, including comments from the developers, can be found on the FreeNAS SourceForge discussion forum. Some users applaud the change, which promises improved hardware compatibility, while others voice concerns regarding the future of their existing setups and lack of ZFS support in Linux."

saddleupsancho writes "Today's NY Times reports that Cormac McCarthy is auctioning the 45-year-old Olivetti manual typewriter on which all his novels, screenplays, plays, short stories, and much of his correspondence were written, to benefit the Sante Fe Institute where he is a Research Fellow. What would happen decades from now if, say, Richard Powers or Neal Stephenson attempted to auction their desktops or laptops? Setting aside completely any comparison among the three authors, is there something more intrinsically interesting and valuable, less ephemeral and interchangeable, about a typewriter vs. a computer as an instrument of literary creation? Or is the current generation just as sentimental about their computer-based devices as McCarthy's generation is about his Olivetti? Would you offer as much for McCarthy's input device if it were a generic PC, Mac, or Linux box as you would for his Olivetti?"

trianglecat writes "The not-for-profit agency Canadian Blood Services has a section of their website based on the Japanese cultural belief of ketsueki-gata, which claims that a person's blood group determines or predicts their personality type. Disappointing for a self-proclaimed 'science-based' organization. The Ottawa Skeptics, based in the nation's capital, appear to be taking some action."
