Exabit Transmission Speeds May Be Possible 98

Posted by timothy from the increasing-oscillations dept.
adeelarshad82 writes "Scientists at UC Berkeley were able to shrink a graphene optical modulator down to 25 square microns in size (small enough to include in silicon circuitry) and were able to modulate it at a speed of 1GHz. The researchers say that modulation speeds of up to 500GHz are theoretically possible. According to the research, due to the high modulation speeds, a graphene modulator can transmit a huge amount of data using spectral bandwidth that conventional modulators can only dream of. Professor Xiang Zhang, in an attempt to boil his group's new findings into consumer-speak, puts it this way: 'If graphene modulators can actually operate at 500GHz, we could soon see networks that are capable of petabit or exabit transmission speeds, rather than megabits and gigabits.'"

Michigan Police Could Search Cell Phones During Traffic Stops 525

Posted by timothy from the gentlemen-do-not-read-each-other's-texts dept.
SonicSpike writes "The Michigan State Police have a high-tech mobile forensics device that can be used to extract information from cell phones belonging to motorists stopped for minor traffic violations. The American Civil Liberties Union (ACLU) of Michigan last Wednesday demanded that state officials stop stonewalling freedom of information requests for information on the program. A US Department of Justice test of the CelleBrite UFED used by Michigan police found the device could grab all of the photos and videos off of an iPhone within one-and-a-half minutes. The device works with 3000 different phone models and can even defeat password protections. 'Complete extraction of existing, hidden, and deleted phone data, including call history, text messages, contacts, images, and geotags,' a CelleBrite brochure explains regarding the device's capabilities." Popular Mechanics has a short conversation with a 4th Amendment lawyer about the practice of slurping cellphone data, too, though it's unclear if the Michigan police are actually using these devices to their full potential.

Comment Property Rights (Score 1) 503

by w00d (#29397999) Attached to: E-book readers ...

I can't really ever see myself buying e-books because I would not own the property rights to them, i.e. I could not give or sell them after reading them, as I do with paper books. As a classical liberal, I hold property rights among the most important rights that I possess as a human, and not being able to do what I wish with something that I have paid money for and ostensibly "own" doesn't jive with me. The day that I can sell or give an e-book to someone else (without having to ask for permission mind you) I may reconsider, but for now I am perfectly happy with dead tree books. They are real property.

Comment Opera *can* block ads, no plugin necessary. (Score 2, Informative) 325

by w00d (#29273317) Attached to: Opera 10.0 Released

Opera has had the ability to block ads and other content for as long as I can remember, long before Firefox itself even existed. All that is required is for one to install a simple .ini file into Opera's user profile directory. The file must be updated manually, but it is simple enough to write a script to automatically download the new file every so often. It may not be as powerful or user-friendly as AdBlock Plus, but it works, and works well.

NASA's LCROSS Spacecraft Discovers Life On Earth 171

Posted by timothy from the that-was-the-control-group dept.
Matt_dk writes "On Saturday, Aug. 1, 2009, the LCROSS spacecraft successfully completed its first Earth-look calibration of its science payload. 'The Earth-look was very successful' said Tony Colaprete, LCROSS project scientist. 'The instruments are all healthy and the science teams was able to collect additional data that will help refine our calibrations of the instruments.' During the Earth observations, the spacecraft's spectrometers were able to detect the signatures of the Earth's water, ozone, methane, oxygen, carbon dioxide and possibly vegetation."

Navigating a Geek Marriage? 1146

Posted by kdawson from the waiting-for-taco-to-weigh-in dept.
JoeLinux writes "I am soon to marry my true love (a girl! yes! they do exist!). She is a literary geek, whereas I am a gaming/Linux geek. Being the RTFM-style geeks that we are, we have been reading up on marriage, making things work, etc. Unfortunately, all of the references seem to be based around an alpha-male jock and a submissive cheerleader-style wife. A lot of the references to incompatibility in the books don't apply to us (neglect due to interest in sports, etc.). What are some of the pitfalls and successes learned in the course of a more geek-oriented marriage?"

"Cash For Clunkers" Program Runs Out of Gas 594

Posted by timothy from the spend-all-you-want-they'll-print-more dept.
Ponca City, We love you writes "The Washington Post reports that Transportation Secretary Ray LaHood has called members of Congress to inform them that the 'cash for clunkers' program will be suspended because the program has run out of money, and congressmen say they intend to ask the Obama administration to divert some funding from the existing economic stimulus package to maintain a scheme that they see as genuinely stimulative. 'Clearly, this has been a very stimulative program that's got consumers back into the car market. It's our hope that possibly more funds can be made available,' says Cody Lusk, president of the American International Automobile Dealers Association." If there is more funding, though, a report on CNET says it may come out of money to have been set aside for renewable energy loans by the US government.

RIAA Says "Don't Expect DRMed Music To Work Forever" 749

Posted by timothy from the just-ask-what-and-whether-you're-buying-or-renting dept.
Oracle Goddess writes "Buying DRMed content, then having that content stop working later, is fair, writes Steven Metalitz, the lawyer who represents the MPAA, RIAA in a letter to the top legal advisor at the Copyright Office. 'We reject the view that copyright owners and their licensees are required to provide consumers with perpetual access to creative works.' In other words, if it stops working, too bad. Not surprisingly, Metalitz also strongly opposes any exemption that would allow users to legally strip DRM from content if a store goes dark and takes down its authentication servers."

Northern Sea Route Through Arctic Becomes a Reality 373

Posted by kdawson from the admiral-peary-i-presume dept.
Hugh Pickens writes "Andrew Revkin writes in the NY Times that since 1553, when Sir Hugh Willoughby led an expedition north in search of a sea passage over Russia to the Far East, mariners have dreamed of a Northern Sea Route through Russia's Arctic ocean that could cut thousands of miles compared with alternate routes. A voyage between Hamburg and Yokohama is only 6,600 nm. via the Northern Sea Route — less than 60% of the 11,400 nm. Suez route. Now in part because of warming and the retreat and thinning of Arctic sea ice in summer, this northern sea route is becoming a reality with the 12,700-ton 'Beluga Fraternity,' designed for a mix of ice and open seas, poised to make what appears to be the first such trip. The German ship picked up equipment in Ulsan, South Korea, on July 23 and arrived in Vladivostok on the 25th with a final destination at the docks in Novyy Port, a Siberian outpost. After that, if conditions permit, it will head to Antwerp or Rotterdam, marking what company officials say would be the first time a vessel has crossed from Asia to Europe through the Arctic on a commercial passage."

First New Nuclear Reactor In a Decade On Track 575

Posted by kdawson from the give-me-the-warm-power-of-the-sun dept.
dusty writes "Plans to bring online the first new US nuclear plant since 1995 are on track, on time, and on budget according to the Tennessee Valley Authority. TVA had one major accident with a coal ash spill of late, and one minor one. The agency has plans and workers in place to have Unit 2 at Watts Bar, near Knoxville, online by 2012. Currently over 1,800 workers are doing construction at the plant. Watts Bar #1 is the only new nuclear reactor added to the grid in the last 25 years. From the article: 'TVA estimates the Watts Bar Unit 2 reactor every year will avoid the emission of about 60 million metric tons of greenhouse emissions linked with global warming. ... TVA began construction of Watts Bar in 1973, but work was suspended in 1988 when TVA's growth in power sales declined. After mothballing the unit for 19 years, TVA's board decided in 2007 to finish the reactor because it is projected to provide cheaper, no carbon-emitting power compared with the existing coal plants or purchased power it may help replace.'"

US Postal Service Moves To GNU/Linux 477

Posted by kdawson from the cobol-package-management dept.
twitter writes "The US Postal Service has moved its Cobol package tracking software to HP machines running GNU/Linux. 1,300 servers handle 40 million transactions a day and cost less than the last system, which was based on a Sun Solaris environment." The migration took a year. The USPS isn't spelling how big the savings are, except that they are "significant."
