An anonymous reader writes "This week Dutch security researcher Niels Teusink described a method of attacking wireless presenter devices at an Amsterdam security conference. He had a demo showing how it is possible to use an Arduino and Metasploit to get remote code execution by sending arbitrary keystrokes to the presenter dongle. He has now released the code and made a blog post explaining how it all works. Better watch out the next time you're giving a presentation using one of these devices!"

schliz writes "Biologists from the University of Leeds have built a computer-controlled replica of a three-spined stickleback fish to study how the behavior of individual fish might influence the movement of others. The so-called 'Robofish' was able to recruit single fish into a group, and cause fish in groups of up to ten to turn in the same direction as itself. The researchers claim that Robofish is the first robotic fish to 'interact convincingly' with a school of fish and convince the whole group to make a sharp turn."

BuzzSkyline writes "University of Texas physicists have built the world's smallest radiometer. The minuscule radiometer is only 2 millimeters across and operates on the same principles as the common light-driven toy, which consists of spinning black and white vanes in a partially evacuated bulb. The researchers attached a mirror to their tiny radiometer and used it to rapidly scan a laser beam. Their hope is that they will be able to incorporate the radiometer into catheters to drive scanners that produce medical images of the interiors of blood vessels and organs. The devices would replace micromotors in conventional catheter-based scanners, eliminating the need to run potentially risky electrical currents into the body."

nickpelling2 writes "In 1918, John F. Byrne invented a truly amazing cipher system, called 'The Chaocipher,' that fit inside a small cigar box, could be operated by a ten-year-old, yet produced practically unbreakable ciphertext (arguably even stronger than the Nazi Enigma machine). But now, thanks to the efforts of Chaocipher fan Moshe Rubin and the generous gift of Byrne's cryptographic effects by his daughter-in-law Pat Byrne to the National Cryptologic Museum, the secrets of the Chaocipher are finally starting to be revealed — it's a great story. To accompany Moshe Rubin's excellent textual description of the Chaocipher, I've posted a 30-second animation of the Chaocipher in action to YouTube, just in case anyone wants to see the most devious cipher of the 20th century in action (sort of)."

RogueWarrior65 writes "In the early 1970s, I was fortunate to discover the Ontario Science Centre in Toronto. For the Gen Y'ers out there who never knew a world without computers, to Gen X'ers, this place was the future. Computer technology was just beginning to be exposed to the world and this museum had the coolest exhibits around, most of which were interactive. One of the exhibits was a machine reminiscent of an old vending machine. On its face was a large circuit board with lights that spelled out the word 'coffee.' There were several dials and a button, which, when pressed, would cause the machine to speak the word. The knobs adjusted various inflections and tonal qualities of the speech. Feeling nostalgic, I inquired of the museum about this exhibit. Was it still there? If not, was it in storage somewhere and could I purchase it. I was told that the machine was developed by Philips Electronics but the exhibit was no longer in their collection. Then I asked Philips about it and was told that no, they have nothing in the archives, no schematics or parts list. A Google search is came up empty as well. Does anyone have any more information on this gadget?"

crimeandpunishment writes "President Obama says it's time to heat up solar power, and he's willing to spend a big chunk of federal money to do it. Saturday the president announced the government is giving nearly $2 billion to companies that are building new solar plants in Arizona, Colorado, and Indiana. The president says this will create thousands of jobs and increase our use of renewable energy."

porcinist writes "On June 23 NASA successfully tested hardware and software on an Armadillo Rocket. With the end of NASA's Constellation program in sight, NASA is starting to focus on new, innovative exploration programs like Project-M. This project is meant to land a robotic humanoid on the moon in a thousand days. To meet this goal NASA teamed with Armadillo Aerospace and Draper Labs (the lab responsible for creating the original Apollo Guidance Computer) to integrate and flight test a real-time navigation system in only seven weeks. This might be the fastest thing NASA has done in 30 years. Maybe NASA is taking Obama's new vision to heart."

arcticstoat writes "Despite the advent of online game stores on all three major consoles, most console gamers apparently still prefer hoarding collections of gaming discs to downloading games. A recent survey conducted by Ipsos in the UK revealed that 64 per cent of the 1,000 users polled would rather have games on physical discs, while only 25 per cent would prefer digital copies. In the survey, 55 per cent of those polled said price was the key factor in determining their interest in downloading games, while 27 per cent said they wanted games available online before they were in the shops. Ipsos' director Ian Bramley explained, 'Interest absolutely drops away when you get to the types of pricing that you might charge for a new physical disc. People's perceptions are that they're not prepared to pay as much for digital content — they make the connection that it's not a physical disc and therefore it should be cheaper.'"

jangel writes "While its strategy for mobile devices might be a mess, Microsoft has announced something we'll all benefit from. The company's patented design for battery contacts will allow users of portable devices — digital cameras, flashlights, remote controls, toys, you name it — to insert their batteries in any direction. Compatible with AA and AAA cells, among others, the 'InstaLoad' technology does not require special electronics or circuitry, the company claims."

snydeq writes "InfoWorld's Bill Snyder discusses the ignominious decline of Dell, one akin to that of Computer Associates, leaving the company forever tainted by scandal and a 'shocking breach of faith with customers.' Dell's pioneering business model and supply chain helped make desktop computing ubiquitous, affordable, and secure. But years of awful quality control and customer service have finally caught up to the company in a very public way that will do irreparable damage to the company for years to come. 'What we've learned about Dell recently doesn't qualify as an understandable mistake. Only a rotten company sells defective computers and lies about it.'"

dogmatixpsych writes "I work in a neuroimaging laboratory. We mainly use OS X but we have computers running Linux and we have colleagues using Linux. Some of the work we do with Magnetic Resonance Images produces files that are upwards of 80GB. Due to HIPAA constraints, IT differences between departments, and the size of files we create, storage on local and portable media is the best option for transporting images between laboratories. What disk file system do Slashdot readers recommend for our external HDDs so that we can readily read and write to them using OS X and Linux? My default is to use HFS+ without journaling but I'm looking to see if there are better suggestions that are reliable, fast, and allow read/write access in OS X and Linux."

CyberSlugGump writes "I am trying to declutter, and I have come across my cheap, off-brand, consumer-grade 802.11b wireless routers, PCMCIA cards, and USB adapters. The routers would still be good as 4-port 100Mb switches, and the other devices have at least 32-bit Windows XP drivers available. However, lack of security beyond WEP and the age of the equipment makes me wonder if it is worth any time putting it to use."

When the PS3 launched in 2006, estimates pegged the price of producing the consoles to be as much as $250 more than the price at which they were sold. Production costs have dropped since then, but there have been several price cuts as well. Now, almost four years later, Sony Worldwide Studios president Shuhei Yoshida says they're finally turning a profit on the hardware. "This year is the first time that we are able to cover the cost of the PlayStation 3,' Yoshida said. 'We aren't making huge money from hardware, but we aren't bleeding like we used to.' In May, Sony began shipping new PlayStation 3 consoles with smaller and more cost-effective graphics chips. Now, Yoshida said, Sony is looking at replenishing retail stock that has been running on empty since January rather than cutting the price. 'When we bring the cost of hardware down, we are looking at opportunities to adjust prices if we believe that will increase demand,' he explained. 'At the moment, we are trying to catch up our production.'"

mattaw writes "In my blog post I describe a system designed to test a route to the potential future of computing. What do we do when we have computers with 1 million cores? What about a billion? How about 100 billion? None of our current programming models or computer architecture models apply to machines of this complexity (and with their corresponding component failure rate and other scaling issues). The current model of coherent memory/identical time/everything can route to everywhere; it just can't scale to machines of this size. So the scientists at the University of Manchester (including Steve Furber, one of the ARM founders) and the University of Southampton turned to the brain for a new model. Our brains just don't work like any computers we currently make. Our brains have a lot more than 1 million processing elements (more like the 100 billion), all of which don't have any precise idea of time (vague ordering of events maybe) nor a shared memory; and not everything routes to everything else. But anyone who argues the brain isn't a pretty spiffy processing system ends up looking pretty silly. In effect, modern computing bears as much relation to biological computing as the ordered world of sudoku does to the statistical chaos of quantum mechanics.

An anonymous reader writes "The much-anticipated, much-mocked 18-button joystick mouse from WarMouse is now shipping. The press release features an impressive set of user quotes from game designer Chris Taylor, new SFWA president John Scalzi, and a doctor who runs a medical software company. Crazy or not, it's obviously more than just a gaming mouse."

DJRumpy was one of several readers to point out rumors that Apple will soon be deploying an update to iOS 4 to combat the iPhone 4 antenna problems we discussed last week. This could be good news for users of the 1.7 million iPhone 4s purchased during the first three days of its release. (And no, Daily Mail, Steve didn't announce a recall, though there's speculation that this problem could be a boon for Android.) An anonymous reader notes an analysis of a teardown of the phone, which found that its parts collectively cost about $188, with the most expensive part — the LCD screen — costing $28.50 by itself. In other Apple news, Germany has demanded that the company "immediately make clear" what data it collects from customers, and what use it makes of that data (perhaps spurred by Google's Wi-Fi sniffing debacle).

eldavojohn writes "This week MIT released a comprehensive, hundred-page report entitled 'The Future of Natural Gas' that outlined the many scenarios the United States faces when aiming to reduce carbon emissions. From the New York Times recap: 'The scenario goes like this, according to MIT: Nuclear power, renewable energy, and carbon capture and sequestration are relatively expensive next to gas. Conventional coal is no longer a major source of power generation in the United States. "Natural gas is the substantial winner in the electric sector: The substitution effect, mainly gas generation for coal generation, outweighs the demand reduction effect."' Will this urging help to produce a policy shift from renewable energy (like wind) to natural gas for the United States?"

MojoKid writes "In the past, NVIDIA has made many claims of how porting various types of applications to run on GPUs instead of CPUs can tremendously improve performance — by anywhere from 10x to 500x. Intel has remained relatively quiet on the issue until recently. The two companies fired shots this week in a pre-Independence Day fireworks show. The recent announcement that Intel's Larrabee core has been re-purposed as an HPC/scientific computing solution may be partially responsible for Intel ramping up an offensive against NVIDIA's claims regarding GPU computing."

SchlimpyChicken writes "Turns out 3D television can be inherently dangerous to developing children, and perhaps to adults as well. There's a malaise in children that can prevent full stereopsis (depth perception) from developing, called strabismus or lazy-eye. It is an abnormal alignment of the eyes in which the eyes do not focus on the same object — kind of like when you watch a 3D movie. As a result, depth perception is compromised. Acting on a hunch, the guys over at Audioholics contacted Mark Pesce, who worked with Sega on its VR Headset over 15 years ago — you know, the headset that never made it to market. As it turns out, back then Sega uncovered serious health risks involved with children consuming 3D and quickly buried the reports, and the project. Unfortunately, the same dangers exist in today's 3D, and the electronics, movie, and gaming industries seem to be ignoring the issue. If fully realized, 3D just might affect the vision of millions of children and, according to the latest research, many adults, across the country."
