Grad Student Invents Cheap Laser Cutter 137

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."

"Choose Your Own Adventure" On Your iPhone 135

If you spent a good portion of your childhood reading the classic "Choose Your Own Adventure" books, you'll be glad to know that you can soon waste countless hours at work turning to random pages on your iPhone. Edward Packard, one of the original authors of the series, has helped create an app called U-Ventures which uses special effects to create a story in the traditional Choose Your Own Adventure format. From the article: "The first U-Venture is a sort of a sequel to a classic title, The Cave of Time. In 'Return to the Cave of Time,' the U-Venture, 'you go back in the cave — you don't have a choice on that,' Packard tells NPR's Neal Conan. But from that point on, the reader chooses her own course."

Woman's Nude Pics End Up Online After Call To Tech Support 197

Tara Fitzgerald couldn't find the nude pictures she planned on sending to her boyfriend, but instead of just taking more, she decided to see if a Dell tech support call could fix her problem. Apparently the tech support guy found them. Unfortunately, he then put them up on a site called "bitchtara."

WD, Intel, Corsair, Kingston, Plextor SSDs Collide 56

J. Dzhugashvili writes "New SSDs just keep coming out from all corners of the market, and keeping track of all of them isn't the easiest job in the world. Good thing SSD roundups pop up every once in a while. This time, Western Digital's recently launched SiliconEdge Blue solid-state drive has been compared against new entrants from Corsair, Kingston, and Plextor. The newcomers faced off against not just each other, but also Intel's famous X25-M G2, WD's new VelociRaptor VR200M mechanical hard drive, and a plain-old WD Caviar Black 2TB thrown in for good measure. Who came out on top? Priced at about the same level, the WD and Plextor drives each seem to have deal-breaking performance weaknesses. The Kingston drive is more affordable than the rest, but it yielded poor IOMeter results. In the end, the winner appeared to be Corsair's Nova V128, which had similar all-around performance as Intel's 160GB X25-M G2 but with a slightly lower capacity and a more attractive price." Thanks to that summary, you might not need to wade through all 10 of the pages into which the linked article's been split.

The 10 Most Absurd Scientific Papers 127

Lanxon writes "It's true: 'Effects of cocaine on honeybee dance behavior,' 'Fellatio by fruit bats prolongs copulation time,' and 'Are full or empty beer bottles sturdier and does their fracture-threshold suffice to break the human skull?' are all genuine scientific research papers, and all were genuinely published in journals or similar publications. Wired's presentation of a collection of the most bizarrely-named research papers contains seven other gems, including one about naval fluff and another published in The Journal of Sex Research."

An Inside Look At Warhammer Online's Server Setup 71

An article at Gamasutra provides some details on the hardware Mythic uses to power Warhammer Online, courtesy of Chief Technical Officer Matt Shaw and Online Technical Director Andrew Mann. Quoting: "At any given time, approximately 2,000 servers are in operation, supporting the gameplay in WAR. Matt Shaw commented, 'What we call a server to the user, that main server is actually a cluster of a number of machines. Our Server Farm in Virginia, for example,' Mann said, 'has about 60 Dell Blade chassis running Warhammer Online — each hosting up to 16 servers. All in all, we have about 700 servers in operation at this location.' ... 'We use blade architecture heavily for Warhammer Online,' Mann noted. 'Almost every server that we deploy is a blade system. We don't use virtualization; our software is somewhat virtualized itself. We've always had the technology to run our game world across several pieces of hardware. It's application-layer clustering at a process level. Virtualization wouldn't gain us much because we already run very close to peak CPU usage on these systems.' ... The normalized server configuration — in use across all of the Mythic-managed facilities — features dual Quad-Core Intel Xeon processors running at 3 GHz with 8 GB of RAM."
