heilbron writes "The Austrian researcher Rene Mayrhofer of the British Lancaster university and his colleague Hans Gellersen developed a technology to simplify a secured wireless connection of mobile devices. With the so-called shake-to-connect technology an authenticated Bluetooth connection between two mobile phones is established by rhythmic shaking. Integrated oscillation sensors, contained in some mobile phone models, form the basis. The two researchers sketched out a prototype, which is intended for Nokia mobile phones. An example is documented in this YouTube video clip. If two mobile phones are shaken together, the software in both devices registers the same shaking frequency and authenticates the radio link. The principle is summed up in a four page PDF document."

Glenn Fleishman writes "EarthLink dropped its final bombshell on city-wide Wi-Fi, saying that it wouldn't put more money in and was talking to their current deployed cities about the future. The company had won bids in dozens of cities, and then backed out of the majority of them before building or finalizing contracts a few months ago. The remaining towns they were building out, like New Orleans, Anaheim, and Philadelphia, will ostensibly be turned off unless local officials come up with scratch or a plan of their own. EarthLink pioneered the model of free-for-fee networks, where there would be no cost or upfront commitment from cities, and EarthLink would charge for network access. Apparently, you can't make money that way."

sufijazz writes "Scientists have gotten tiny robots to not only integrate into cockroach society but also control it. 'This experiment in bug peer pressure combined entomology, robotics and the study of ways that complex and even intelligent patterns can arise from simple behavior. Animal behavior research shows that swarms working together can prosper where individuals might fail, and robotics researchers have been experimenting with simple robots that, together, act a little like a swarm.' The BBC also has a video story on this."

cell-block-9 writes "Today the last section of the old Edison DC power grid will be shut down in Manhattan. 'The last snip of Con Ed's direct current system will take place at 10 East 40th Street, near the Mid-Manhattan Library. That building, like the thousands of other direct current users that have been transitioned over the last several years, now has a converter installed on the premises that can take alternating electricity from the Con Ed power grid and adapt it on premises.' I guess Tesla finally won the argument."

StonyandCher writes "Scott Maxwell must have one of the best IT jobs in the solar system, driving NASA's Mars Rovers. Behind every robot is a driver. He's one of 14 Rover Drivers that work in NASA's California-based Jet Propulsion Laboratory. Maxwell discusses what makes up an average work day, the highlights of the project, how he got the job, and the tools he uses in his work. A great look at the team of dedicated IT workers behind the robots, plotting the every move of NASA's twin robot geologists, Spirit and Opportunity, since they first landed on Mars at the start of 2004."

Tim Danhamn writes "SmartPlanet.com, a green-focused Web site, has put up an article about the best way to recycle your old tech, including local recycling centers and reusing old technology in other ways. I'm about to upgrade to a new PC and I have a lot of old radios, MP3 players and other electronic goods lying around the house. The article though is mostly about solutions in the UK, so I want to know - what is the best way to recycle old tech in the US?"

Ian Lamont writes "Are laptops really as great as they're cracked up to be? We love their portability, and we've been charting the steady rise of laptop sales for years. Yet while many of us depend on them for work, our IT departments view them with mixed feelings. IT managers point to wi-fi configuration, complicated authentication procedures, and eight other issues as making their jobs a lot harder. What else is missing from the list of laptop limitations? What would you like to see in the next generation of laptop computers?"

BaCa sent in this article about stealing network access that opens, "Sophos has revealed new research into the use of other people's Wi-Fi networks to piggyback onto the internet without payment. The research shows that 54 percent of computer users have admitted breaking the law, by using someone else's wireless internet access without permission." Of course, online polls being what they are, the results are hardly a plank for a full investigation, but a good share of the answerers did 'fess up to it as well.

mcpublic writes "The team of 'digital archaeologists' who developed the technology behind the Intel Museum's 4004 microprocessor exhibit have done it again. 36 years after Intel introduced their first microprocessor on November 15, 1971, these computer historians have turned the spotlight on the first application software ever written for a general-purpose microprocessor: the Busicom 141-PF calculator. At the team's web site you can download and play with an authentic calculator simulator that sports a cool animated flowchart. Want to find out how Busicom's Masatoshi Shima compressed an entire four-function, printing calculator into only 1,024 bytes of ROM? Check out the newly recreated assembly language "source code," extensively analyzed, documented, and commented by the team's newest member: Hungary's Lajos Kintli. 'He is an amazing reverse-engineer,' recounts team leader Tim McNerney, 'We understood the disassembled calculator code well enough to simulate it, but Lajos really turned it into "source code" of the highest standards.'"

cweditor writes "Rob Mitchell shows how he measured energy use of all his home office equipment, and then targeted the energy pigs for replacement. With better equipment choices, he'd save $90/year. If you've got more than a couple of computers and printers at home (and if you're a Slashdot reader, you probably do), the savings would be a lot higher. Includes detailed formulas as well as a spreadsheet on monitor energy usage."

BOfH writes "The BBC is reporting that following a 14-year rebuild project, the Colossus computer is once again cracking codes at Bletchley Park." They will crack WWII-era encrypted messages, and compete against modern PCs. Fun stuff for crypto nerds and history buffs.

Actual Reality writes "It is ironic to me that much of the same sentiment that thwarted the nuclear power industry back in the 80's is partially responsible for reviving it. Nuclear power is very clean compared to any power source that burns fuel. The US has missed several advancements in nuclear technology. We can only hope that environmental concerns will not again stifle our progress."

Nick Breen writes "Are solid state drives becoming a reality? Loyd Case over at ExtremeTech has written an article concerning the current state of SSD with a comparison between a Samsung 64GB SATA and a Super Talent 32GB SATA. While they showed impressive speed rates when placed against a hard disk drive, the occasional sporadic statistic (and high cost) indicate they're not quite ready for the mainstream. Dell and Alienware have been shipping laptops with SSDs for months now, and Apple may be rolling out one of their own next year. Is the time of the solid-state drive almost at hand? Does anyone have any first-hand, practical experience with SSD?"

Via Rock Paper Shotgun and Primotech, the latest in Valve's ongoing PC hardware survey via the Steam service. Some very interesting stuff in there, though probably nothing too surprising. From RPS's analysis: "Vista has shown a small increase in representation, but clearly nowhere near where Microsoft would have desperately hoped. Previously 7.99% of gamers were using the latest operating system. Now it's 16.91%, with a vast 81.13% sticking with XP. Rather confirming Valve's position on DX10, and what a massive waste of time it is developing for Vista only."

I have a 15" laptop and have used a number of lap desks over the years, and none have satisfied me. I don't really need a mouse pad space (trackpad) but it wouldn't hurt to have a mouse space available for gaming. I sit in a very large chair so using the armrests isn't an option. I'm just curious what experience you all have with various lap desks. Any particular favorites? I've seen shelves that you can slide over your chair, to glorified pieces of plywood, but what have you turned up?

coondoggie writes "South Korea officials today said they hope to build two robot theme parks for $1.6 billion by 2013. The parks will feature a number of attractions that let visitors interact with robots and test new products. "The two cities will be developed as meccas for the country's robot industry, while having amusement park areas, exhibition halls and stadiums where robots can compete in various events," the ministry said. The theme parks are not a big surprise because South Korea loves its robots. Earlier this year the government of South Korea said it was drawing up a code of ethics to prevent human abuse of robots — and vice versa."

Stony Stevenson writes to tell us that in celebration of the opening of the National Museum of Computing, members of the public are being challenged to take on a rebuilt version of Colossus, the world's first programmable digital computer. The Cipher Challenge will take two groups of amateur code breakers and pit them against one of the original Lorenz cipher machine used by the German High Command during World War II. "The encrypted teleprinter message will be transmitted by radio from colleagues in Paderborn, Germany, and intercepted at Bletchley Park by the two code-breaking groups, one using modern PCs and the other using the newly rebuilt Colossus Mark II."

miller60 writes "If your data center's cooling system fails, how long do you have before your servers overheat? The shrinking window for recovery from a grid power outage appears to have been an issue in Monday night's downtime for some customers of Rackspace, which has historically been among the most reliable hosting providers. The company's Dallas data center lost power when a traffic accident damaged a nearby power transformer. There were difficulties getting the chillers fully back online (it's not clear if this was equipment issues or subsequent power bumps) and temperatures rose in the data center, forcing Rackspace to take customer servers offline to protect the equipment. A recent study found that a data center running at 5 kilowatts per server cabinet may experience a thermal shutdown in as little as three minutes during a power outage. The short recovery window from cooling outages has been a hot topic in discussions of data center energy efficiency. One strategy being actively debated is raising the temperature set point in the data center, which trims power bills but may create a less forgiving environment in a cooling outage."

An anonymous reader writes "General Dynamics Canada and Secure Computing have partnered to develop Meshnet, a hardware/software firewall designed to protect networks and digital devices inside tanks and other military vehicles from hostile computer and virus attacks. Without adequate protection a tech savvy enemy can infiltrate networks, manipulate information, and deny crews the data they need to participate in modern warfare. Exactly such an event happened last year to an Israeli crew, when hackers from Hezbollah eavesdropped on their communications. 'The system uses Secure Computing's off-the-shelf Sidewinder Security Appliance ... Sidewinder consolidates all major Internet security functions into a single system, providing "best-of-breed" antivirus and spyware network protection "against all types of threats, both known and unknown," according to Secure Computing.'"

eldavojohn writes "There's a new antenna that consists of plasma and essentially vanishes when you turn it off. While it may seem to not have many uses in the commercial world, it is very important to military personnel who risk detection or for anybody wishing to avoid signal jamming."
