smackay writes "As CHARLI takes his first steps, anxious onlookers stand ready to catch him if he falls. His stride is short, but upright, as one foot is placed in front of the other in the basement of Virginia Tech's Randolph Hall. But CHARLI is no toddler. He is a 5-foot-tall humanoid robot. Video of this ground-breaking robot included."

An anonymous reader writes "The University of Tokyo is developing a Project-Natal-style interface for mobile phones, which allows you to interact with a phone by waving your finger around. Members of the Ishikawa-Komuro Lab have used a high-frame-rate camera to track the motion of a finger and recognise input gestures. The touchless interface can be used to navigate around a phone's screen and even to type."

robotsrule writes "This video shows a WowWee Rovio mobile spy robot being piloted remotely over a Skype video call using thought, facial gestures, and head movements, with the help of the Emotiv Systems EPOC 14-electrode EEG headset with built-in gyroscope. An accompanying article explains in detail how the system works and what steps were taken with the Emotiv systems SDK to interface with the EPOC headset along with code samples. The system is based on Robodance 5, a free robot control program for consumer robot owners that will be out in beta on May 20, 2010."

Andrew Smith writes "My search for an alternative to the iPhone has been long and frustrating. On paper, the HTC Desire is the first serious challenger to the iPhone's reign as king of phones. But how does it compare in use? There is much good and much bad. (This review is primarily for UK readers as HTC's new handset, the Incredible, will not be available [in the UK].)"

G3ckoG33k writes "An article at The Register Hardware describes how Hasselblad film cameras dating back to 1957 can be given a new life using a digital back to get images at a super resolution of 39 megapixels. From the article: 'The CFV-39 digital back allows you to get those cameras out from the last century and use the V-System cameras with their beautiful glass once again, it simply fits in place of where the roll film used to be. Hasselblads have never been inexpensive, but talk about a return on investment. Here is a manufacturer looking after a fiercely loyal user-base and along with it offering what could be seen as the ultimate green camera system.' Oh, by the way most pictures taken during the Apollo space program in the 1960s were taken with Hasselblad." Hasselblad's been making digital backs for quite a while now, but this one's very impressive in speed (and cost — "only" about $14,000) compared to earlier models.

JoshuaInNippon writes "In a brief press release buried within Sony Japan's website, the company announced that it would be ending sales of the classic 3.5-inch diskette in the country in March 2011. Sony introduced the size to the world in 1981, and it saw its heyday in the 1990s. Sony has been one of the last major manufacturers to continue shipments of the disk type it helped develop, but had ended most worldwide sales in March of this year. The company's production of the 3.5-inch floppy ceased in 2009. Sony noted demand, or lack thereof, as the reason. The company's withdrawal is one of the final acts in the slow death of the floppy era."

jeremyz writes "With the inclusion of 802.11n in more and more Wi-Fi devices, the WRT54GL is losing its usefulness, even though it's still the de-facto standard for open source, Linux-running wireless routers. I've been looking around for a 802.11n router to replace the WRT54GL, but haven't really found anything besides the Netgear's WNR3500L. At first look, the WNR3500L looked great, but after some further investigation, I found that Netgear hasn't released all of the source, as they should have to comply with the GPL. Are there any good 802.11n routers to replace my aging WRT54GL?"

An anonymous reader writes "The Department of Defense has just released a long restricted report (PDF) by the JASON group entitled Radical Computing. This 1984 study outlines a number of alternate computing methods that could 'result in a radical improvement in computing.' The study attempts to explain the paradox of how the Russian lag in developing VLSI chips curiously did not critically hinder their accomplishments in space missions, ICBMs and chess computation. The authors speculate that the Russians might have achieved breakthroughs in alternative computing methods such as residue arithmetic and symbolic computing. (More cynical types assume the Russians bought or stole US chips from the French or other too-helpful go-betweens.)"

vikingpower writes "Built in reaction to a major flood that killed 1,800 in the '50s, the Dutch system of dikes, sluices, surge barriers, and dams has been dubbed 'one of the seven wonders of the modern world' by the American Society of Engineers. Now there are proposals to use the system differently, e.g. as tidal power plants, by punching holes in them. Any civil engineer's mouth will probably be watering when thinking of the mega-projects this could give rise to."

AzTechGuy writes "Arizona Public Service Co., Arizona's largest power company, is implementing a test program that would put customers' thermostats under their control to help balance power needs during critical peak usage times. APS will be able to remote control the customers' thermostats to control power draw from their A/C when there is a critical power transmission issue on the grid. Customers will be able to override these settings if they desire."

Hugh Pickens writes "NPR reports that German researchers have tested a new technology called eyeDriver that tracks a driver's eye movement and, in turn, steers the car in whatever direction they're looking at speeds up to 31 mph. 'The next step will be to get it to drive 60 miles per hour,' says Raul Rojas, an artificial intelligence researcher at Berlin's Free University. A Dodge Caravan fitted with eyeDriver has been tested on the tarmac at an abandoned airport at Tempelhof Airport. However, it remains unclear when — or if — the technology will be commercialized, as questions about safety and practicability abound: What about looking at a cute girl next to the road for a few seconds? Not to mention taking phone calls or typing a text while driving. But the researchers have an answer to distracted drivers: 'The Spirit of Berlin' is also an autonomous car equipped with GPS navigation, scores of cameras, lasers, and scanners that enable it to drive by itself. And should the technology-packed vehicle have a major bug, there's still an old fashioned way of stopping it. Two big external emergency buttons at the rear of the car allow people outside to shut down all systems."

mdsolar writes "A new report from a nuclear watchdog group finds that the Nuclear Regulatory Commission 'is ignoring its oversight and enforcement responsibilities at the nation's increasingly leaky, uninspected and unmaintained nuclear power plants.' Because of this lack of oversight, 'at least 102 reactor units are now documented to have had recurring radioactive leaks into groundwater from 1963 through February 2009.' So, the leak at Vermont Yankee that Slashdot has been following is not just a fluke, but is systemic."

schliz writes "IBM scientists have created the smallest 3-D map of the earth, so small that 1,000 maps could fit on a grain of salt (YouTube video from IBM). The 500K-pixel map was created in 2 minutes 23 seconds. Using a tiny, heated silicon tip, the technique reached a resolution of 15nm — comparable to the 10nm achievable by the more complex electron beam lithography. The researchers believe that smaller resolutions are feasible. Potential applications range from fast prototyping for CMOS nanoelectronics to fabricating shape-matching templates for self-assembling nano-rods or nano-tubes, IBM says. The researchers also produced a billion-to-one scale model of the Matterhorn." This is very much a laboratory technique at the moment, at least five years from commercial use.

alvin67 writes "Microsoft Evangelist Pete Brown rants about the lack of pixels available in today's LCD screens: 'OK, that's it. I've had it. I want my pixels, damn it! For a while, screen resolution has been going up on our desktop displays. The trend was good, as I've always wanted the largest monitor with the highest DPI that I could afford. I mean, I used to have one of the first hulking 17-inch CRTs on my desk. I later upgraded to a 21-inch job that was so huge, that if you didn't stick it in a corner, it took up the whole desk. It was flat-panel, though and full of pixels. It cost me around $1,100 at the time." After some years of improvements, we've regressed, in Brown's opinion: "At the rate we were going for a while, we should have had twice or three times the DPI on a 24- or 23-inch screen. But nooo."

Annirak writes "With the bottom dropping out of the magnetic disk market and SSD prices still over $3/GB, I want to know if there is a way to to get the best of both worlds. Ideally, a caching algorithm would store frequently used sectors, or sectors used during boot or application launches (hot sectors), to the SSD. Adaptec has a firmware implementation of this concept, called MaxIQ, but this is only for use on their RAID controllers and only works with their special, even more expensive, SSD. Silverstone recently released a device which does this for a single disk, but it is limited: it caches the first part of the magnetic disk, up to the size of the SSD, rather than caching frequently used sectors. The FS-Cache implementation in recent Linux kernels seems to be primarily intended for use in NFS and AFS, without much provision for speeding up local filesystems. Is there a way to use an SSD to act as a hot sector cache for a magnetic disk under Linux?"

An anonymous reader writes "In 2008, the Seattle Police illegally arrested security consultant Eric Rachner for refusing to show ID. After Rachner filed a formal complaint, he was prosecuted for obstructing, and the police claimed that videos of the arrest were unavailable — until Rachner's research uncovered proof that the police had the videos all along." It's an interesting story of how he figured out how the system in use by Seattle police automatically tracks deletion, copying, or other uses of the recorded stream.

toruonu writes "How do you keep track of what's in your datacenter, where it is, what it's connected to and what is it doing right now? I mean I have built a datacenter from scratch over the years and I have machines from Sun, IBM, HP, Supermicro. I have machines that are simple workernodes and machines that are heavy grade storage consolidation machines. Then there are tens of switches, some for interconnect, some for management and don't get me started on the UPSs etc. So how does one keep any kind of decent track of such a system as the current form of twiki pages with various tables just doesn't cut it anymore and I'm looking for a freeware solution that could actually show me a visual representation of the various nodes in the racks, their connections and dependencies. Just to give a simple example, if I'm going to disconnect UPS #3 right now and swap switch #5, which machines should I even consider taking offline?" (The best-looking such system I've seen was being used at OSCON at a display booth for the Open Source Lab, and I think it was home-grown. Anyone who can shed light on that system?)

kkleiner writes "Adept's Quattro, a placement and sorting arm, took the title of fastest robot last year, but it was only recently during National Robotics Week that it met its most gruesome opponents: nerds with Wiimotes. Visitors tried to keep the Quattro from placing and sorting on a small mechanized platform by moving it using the Nintendo video controller. The bottom line is that when it comes to simplified and repetitive tasks there's really no beating robotic prowess."

gyrogeerloose writes "An article in the London Evening Standard claims that Apple has made an $8 billion offer to acquire ARM Holdings. For those few Slashdotters who don't already know, ARM makes the processor chips that power Apple's iPad, iPhone, and iPod Touch. However, ARM processors are also used by other manufacturers, including Palm and, perhaps most significantly, companies building Android phones. This explains why Apple might be willing to spend so much on the deal — almost 20% of its cash reserves. Being able to control who gets to use the processors (and, more importantly, who doesn't) would give Apple a huge advantage over its competitors."

anethema writes "iPhone hacker planetbeing, from the iPhone Dev Team, has successfully ported the Android OS over to the iPhone. He is doing it on a first-generation iPhone, but others may be possible. The port is pretty functional, with data, voice, and many apps working, although it is running a bit sluggish and buggy at the moment. There appears to be much work left."
