Who Invented the Linux-Based Wireless Router?
mtaht writes "I've just had the interesting experience of being deposed to talk about one of the first embedded, Linux-based, wireless routers. Our (free!) 1998 publication of how to make one predates patent #7035281, filed September 13, 2000, by someone else. Their patent was recently granted and is now being disputed in court, in part using our how-to as an example of prior art. The lawsuit continues; the case goes before a judge shortly, and a jury trial if necessary is scheduled for the spring. I find myself plagued with the question: So... who invented the embedded Linux based wireless router? What relevance does 'who' have, when there is such an enormous confluence of ideas from thousands of people? What constitutes invention, anyway?"

Vint Cerf Keeps Blaming Himself For IPv4 Limit
netbuzz writes "Everyone knows that IPv4 addresses are nearly gone and the ongoing move to IPv6 is inevitable if not exactly welcomed by all. If you've ever wondered why the IT world finds itself in this situation, Vint Cerf, known far and wide as one of the fathers of the Internet, wants you to know that it's OK to blame him. He certainly does so himself. In fact, he does so time and time and time again."

Physicists Say Graphene Could Create Mass
eldavojohn writes "Graphene has gotten a lot of press lately. The Nobel prize-winning, fastest-spinning, nanobubble-enhanced silicon replacement is theorized to have a new, more outlandish property. As reported by Technology Review's Physics Blog, graphene should be able to create mass inside properly formed nanotubes. According to Abdulaziz Alhaidari's calculations, if one were to roll up graphene into a nanotube, this could compactifiy dimensions (from the sheet's two down to the tube's one), and thus 'the massless equations that describe the behavior of electrons and holes will change to include a term for mass. In effect, compactifying dimensions creates mass.' What once would require a massive high-energy particle accelerator can now be tested with carbon, electricity, and wires, according to the recent paper."

Bible.com Investor Sues Company For Lack Of Profit
The board of Bible.com claims that it is easier for a camel to pass through the eye of a needle, than to make money on the domain name, but an angry shareholder disagrees. From the article: "James Solakian filed the lawsuit in Delaware's Chancery Court against the board of Bible.com for breaching their duty by refusing to sell the site or run the company in a profitable way. The lawsuit cites a valuation done by a potential purchaser that estimated bible.com could be worth more than dictionary.com, which recently sold for more than $100 million."

US Presidential Nuclear Codes 'Lost For Months'
Martin Hellman writes "Former Chairman of the Joint Chiefs of Staff, Gen. Hugh Shelton, has dropped a nuclear bombshell, metaphorically speaking. Shelton's recently released memoir Without Hesitation: The Odyssey of an American Warrior, asserts that an aide to President Clinton lost a card containing key phrases needed for ordering a nuclear strike, and that the codes were missing for months. This confirms a similar allegation, made in 2004 by Lt. Col. Robert Patterson, a military aide who frequently carried the 'nuclear football' during the Clinton presidency. Unfortunately, human error within the nuclear weapons complex is a frequent and dangerous occurrence."

Recommendations For Home Virtualization?
An anonymous reader writes "I'll have to upgrade my home computers sometime in the next few months and I'm thinking it's time to swallow the virtualization pill. Besides the ease of switching between Windows and Ubuntu, I'm looking mainly for the ability to save machine state in order to be able to revert to a known working state. Googling turns up mostly guides from 2009 and earlier. Is VMWare ESX pretty much the way to go? Performance does matter — not for gaming but I am heavily into photography, so apps like Lightroom and Photoshop need to run well. Thanks for any insight."

Heroic Engineer Crashes Own Vehicle To Save a Life
scottbomb sends in this feel-good story of an engineer-hero, calling it "one of the coolest stories I've read in a long time." "A manager of Boeing's F22 fighter-jet program, Innes dodged the truck, then looked back to see that the driver was slumped over the wheel. He knew a busy intersection was just ahead, and he had to act fast. Without consulting the passengers in his minivan — 'there was no time to take a vote' — Innes kicked into engineer mode. 'Basic physics: If I could get in front of him and let him hit me, the delta difference in speed would just be a few miles an hour, and we could slow down together,' Innes explained."

Where Are the Original PC Programmers Now?
Esther Schindler writes "In 1986, Susan Lammers did a series of interviews with 19 prominent programmers in a Microsoft Press book, Programmers at Work. These interviews give a unique view into the shared perceptions of accomplished programmers, the people who invented the tools you use today. In Programmers Who Defined The Technology Industry: Where Are They Now?, I tracked down the fate of these prominent developers — from Robert Carr (Framework) to Dan Bricklin (VisiCalc) to Toru Iwatani (author of Pac Man, I'm glad you asked). The article quotes the developers' 1986 views on programming, the business, and the future of computing. In two cases (Bricklin and Jonathan Sachs, author of Lotus 1-2-3) I spoke with them to learn if, and how, their views had changed. One meaty example: In 1986, Bill Gates said, on Microsoft's future: 'Even though there'll be more and more machines, our present thinking is that we won't have to increase the size of our development groups, because we'll simply be making programs that sell in larger quantities. We can get a very large amount of software revenue and still keep the company not dramatically larger than what we have today. That means we can know everybody and talk and share tools and maintain a high level of quality.' At the time, Microsoft had 160 programmers."

Jeep Wrangler Call of Duty Black Ops Edition
gadgetking writes "When I first saw this I thought it was a joke — the Jeep Wrangler Call of Duty: Black Ops Edition. Seriously? I mean I like my COD first person shooter game as much as the next nerd but this really shows how mainstream video games have become. From the article: 'The Jeep brand today announced it has been named exclusive automotive partner by Activision for Call of Duty: Black Ops, and that they're making a COD Jeep. Hitting show floors next month, this limited-edition Jeep Wrangler will be available for a MSRP of $30,625 for the two-door model and $33,500 for the four-door. The 2011 Jeep Wrangler Call of Duty: Black Ops Edition comes standard with "aggressive 32-inch tires, unique military style and Call of Duty graphics."'"

Astonishing Speedup In Solving Linear SDD Systems
eldavojohn writes "A new paper (PDF) out of Carnegie Mellon University shows how to solve symmetric diagonally dominant linear systems much faster than before. The technique employs graph theory, randomized algorithms, and linear algebra to achieve an astonishing advantage over current methods to solve such systems. From the article: 'The result is a significant decrease in computer run times. The Gaussian elimination algorithm runs in time proportional to s^3, where s is the size of the SDD system as measured by the number of terms in the system, even when s is not much bigger the number of variables. The new algorithm, by comparison, has a run time of s*[log(s)]^2. That means, if s = 1 million, that the new algorithm run time would be about a billion times faster than Gaussian elimination.' Developers out there who maintain matrix packages and linear algebra tools might want to take a peak at the paper. Anyone who has modeled real-world systems will be able to tell you that speedups in linear algebra algorithms have a weighty effect on efficiency in simulations — especially as one approaches the theoretical limits of optimality. This research is currently being presented at the IEEE Symposium on Foundations of Computer Science."

Programmable Magnets
Martin Hellman writes "A few weeks ago Popular Mechanics awarded one of its Breakthrough Awards for the invention of 'programmable magnets.' Instead of having a single North or South pole, these clever devices have an array of North and South poles. If a matching device with exactly the same array is aligned with the first one, they will experience strong repulsion, just like two single North poles do when brought near one another. If the matching device has the complementary array (North and South interchanged), with correct alignment the two devices will attract. But a slight misalignment will cancel most of the force. Other configurations are possible as well, allowing frictionless magnetic gears and exploding toys. The inventor, Larry Fullerton, used techniques similar to those from CDMA modulation. (Watch the intro video for a brief explanation. While I don't understand magnetism that well, I do understand CDMA and carrying over those ideas to magnetic arrays does make sense to me.)"

Giant Lab Replicates Category 3 Hurricanes
Pickens writes "The WSJ reports that a new $40 million research center built by the Institute for Business & Home Safety in Richburg, SC features a massive test chamber as tall as a six-story building that can hold nine 2,300-square-foot homes on a turntable where they can be subjected to tornado-strength winds generated by 105 giant fans to simulate a Category 3 hurricane. The goal is to improve building codes and maintenance practices in disaster-prone regions even though each large hurricane simulation costs about $100,000. The new IBHS lab will be the first to replicate hurricanes with winds channeling water through homes and ripping off roofs, doors and windows. The new facility will give insurers the ability to carefully videotape what happens as powerful winds blow over structures instead of relying on wind data from universities or computer simulations. The center will also be used to test commercial buildings, agriculture structures, tractor-trailers, wind turbines, and airplanes."

Google Is Going Postal In Sweden
An anonymous reader writes "Google will start to collaborate with the Swedish Postal Service (Swedish original) to sell direct marketing to small businesses, both in the form of fliers (delivered by the Swedish Postal Service) and keyword advertising in Google Search. The area of distribution for the fliers is selected in Google Maps. Google will also will provide templates for the design of the fliers.The idea was concieved within the Swedish Postal Service."

AMD's New Radeon HD 6870 and 6850 Cards Debut
MojoKid writes "AMD has officially launched their new Radeon HD 6800 series of graphics cards and the company has managed to drive cost and power consumption out of the product, while increasing performance efficiencies in the architecture. The Radeon HD 6870 and Radeon HD 6850 are new midrange cards that offer similar performance to previous generation high-end offerings, but at significantly lower price points and with an enhanced tessellation engine for better support of next generation DX11 game engines. The cards compete well with NVIDIA's GeForce GTX 470 and 460 products, besting them in some scenarios but trailing in others. Word is AMD is readying their flagship high-end Radeon 6900 family for release in Q4 as well."

SD Adapter For Dreamcast Released
YokimaSun writes "The Dreamcast was the last console by Sega that had innovations that today's consoles have taken on board, i.e. broadband online gaming and innovative gaming controllers (such as the fishing controller). The console still lives on today, thanks to the support of the homebrew community that still churns out games and emulators and also the odd commercial release for the console by independent developers. Today the spark has been ignited by the fascinating release of an SD adapter for the Dreamcast that allows homebrew games to be played without the need to burn to disc. It's time to dust off those Dreamcast consoles and get back into free gaming. The same company have also released a Dreamcast modified with VGA support and a front-loading SD slot and its own BIOS. Awesome to relive some of those Dreamcast classics."

NASA Strikes Gold and Water On the Moon
tcd004 writes "The PBS NewsHour reports: there is water on the moon — along with a long list of other compounds, including mercury, gold and silver. That's according to a more detailed analysis of the cold lunar soil near the moon's South Pole. The results were released as six papers by a large team of scientists in the journal, Science Thursday. [Note: Nature's papers are behind a paywall; for a few more details, reader coondoggie points out a a story at Network World.] The data comes from the October 2009 mission, when NASA slammed a booster rocket traveling nearly 6,000 miles per hour into the moon and blasted out a hole. Trailing close behind it was a second spacecraft, rigged with a spectrometer to study the lunar plume released by the blast. The mission is called LCROSS, for Lunar Crater Observer and Sensing Satellite."

On Several Fronts, US Gov't Prepares To Regulate Online Privacy
storagedude writes "There are at least five US government efforts underway to regulate data and online privacy, according to a new US government internet policy official, who sees some kind of privacy regulation as likely. Ari Schwartz, who left the Center for Democracy and Technology two months ago to become senior internet policy advisor at the National Institute of Standards and Technology, says issues like Facebook's never-ending privacy concerns are making some kind of a national law or regulation more and more likely. He thinks segregating identity from data isn't enough; the data must then be aggregated after identity is stripped out. He also called for objective measures of privacy compliance."

In Florida, a Cell Phone Network With No Need For a Spectrum License
holy_calamity writes "Technology Review reports on a cell phone network in Fort Lauderdale, Florida, like no other. Instead of paying to reserve a section of wireless spectrum its owner, xG Technology, uses cognitive radios that steer signals through the unlicensed 900MHz band more normally used by cordless phones and baby monitors. The radios in both handset and base station scan for gaps left by other devices in that band and make dynamic connections that constantly hop frequencies to ensure a good link. The network is designed to show off the tech, which the company says could be used in conventional cellphones to access extra spectrum or white spaces devices."

Google Testing High-Speed Fiber Network At Stanford Res Halls
GovTechGuy writes with this news from "Google has reached an agreement to build its first ultra-high speed broadband network near Stanford University, the search giant announced on Thursday. The agreement with Stanford means the university's residential subdivision will be the first place to test Internet speeds up to one gigabit per second, more than 100 times faster than the typical broadband connection in the US. The plan is to break ground early next year." That might just be worth $50,576 per year to have.

Open Source-Friendly Smartphones For the Small Office?
Thunderstruck writes "I work in a small office with just two computers. Both machines run long-term-service releases of Ubuntu, with Gnome, and Evolution for scheduling, contact management and electronic mail. We plan to stick with Linux long-term. For telephone service, we're using smartphones. In order to keep everything straight, we need phones that can synchronize easily with the calendars and contact data on each owner's desktop machine. We cannot use cloud based services for this function due to ethics rules, and for security reasons. Right now, we do all of this with older Palm phones, but these are a dying breed. What options are out there right now for phones that will sync with Evolution (or another good Linux PIM suite) which do not require data to go through the cloud first?"

Why Silicon Valley Won't Be the Green Car Detroit
thecarchik writes "NPR boldly pronounced, 'The new automobile of the 21st century is likely to benefit from the culture of Silicon Valley, where people are used to taking a chip, a cell or an idea and working on it until it becomes something big.' We've thought about it for a year, and discussed it with many people. And we don't believe it. Silicon Valley is the wrong place to build an auto industry, for three main reasons."

Fermilab To Test Holographic Universe Theory
eldavojohn writes "Scientists at Fermilab have decided that it's high time they build a 'holometer' to test the smoothness of space-time. Theoretical physicists like Stephen Hawking have proposed that space-time is not smooth but it's been a lot of math and no actual data. The Fermilab team plans to build two relatively small devices that act as 'holographic interferometers' to measure the shaking or vibration in split beams of light traveling through a vacuum. If the team finds the shaking in their measurements and records them, the theory of a holographic universe will have some evidence of non-smoothness in space-time and perhaps a foothold in bringing light to the heavily debated theoretical physics."

Early Review of 11" Macbook Air
adeelarshad82 writes "Apple's latest entry into the ultraportable space is no netbook, even though it's the closest the company has come to making one. Its chassis is, amazingly, even thinner than the original MacBook Air, with a screen two sizes smaller. Moreover, the MacBook Air's 11.6-inch widescreen is not the only first for Apple; so is its 1,366-by-768 resolution. Although Apple found a way to squeeze in two USB ports and a speedy solid-state drive (SSD), the MacBook Air (11-inch) is not nearly as feature-packed or as fast as the rest of the MacBook family, primarily because its 1.4GHz Intel Core 2 Duo SU9400 Ultra-Low Voltage (ULV) processor is running on previous-generation Intel technology. Still, it will give the latest batch of Consumer Ultra Low Voltage (CULV) laptops a run for their money."

Cheap Software Tools Give New Life To Stop-Motion Animation
An anonymous reader writes "The NY Times reports that a wide variety of new stop motion animation tools are making it simpler to create stop-motion movies. The new tools are helping animators run more than three times faster than they did just a few years ago. Some even say that stop motion is cheaper than computer generated animation. Tools like Dragon Stop Motion, Stop Motion Pro and iKitMovie are just a few of the tools that are reinvigorating the space."

How Google Avoided Paying $60 Billion In Taxes
bonch writes "Google only pays a 2.4% tax rate using money-funneling techniques known as the 'Double Irish' and the 'Dutch Sandwich,' even though the US corporate income tax is 35%. By using Irish loopholes, money is transferred legally between subsidiaries and ends up in island sanctuaries that have no income tax, giving Google the lowest tax rate amongst its technology peers. Facebook is planning to use the same strategy."
