Samsung's New Carbon Nanotube Color E-Paper 87

Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost completely translucent and only 50 nanometers thick. "The company also mentions that the EPD [electrophoretic displays] has important advantages over conventional flat panel displays. EPDs have very low power consumption and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power consumption is lowered due to the EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing."

TrueCrypt 6.0 Released 448

ruphus13 writes "While most of the US was celebrating Independence Day, the true fellow geeks over at TrueCrypt released version 6.0 of TrueCrypt over the long weekend. The new version touts two major upgrades. 'First, TrueCrypt now performs parallel encryption and decryption operations on multi-core systems, giving you a phenomenal speedup if you have more than one processor available. Second, it now has the ability to hide an entire operating system, so even if you're forced to reveal your pre-boot password to an adversary, you can give them one that boots into a plausible decoy operating system, with your hidden operating system remaining completely undetectable.' The software has been released under the 'TrueCrypt License,' which is not OSI approved."

Submission + - TV star says privacy overrated, gets burned (boingboing.net)

HardYakka writes: Boing Boing has the story of a British television celebrity who wrote an article saying people shouldn't worry about their financial information being leaked and to prove his point, he gave out his account details. In short order, someone withdrew money from his account and the bank says it can't trace it or stop the thief from doing it again. I think he might value his privacy a little more now.

Submission + - U.S. courts consider legality of laptop inspection

ceide2000 writes: "The government contends that it is perfectly free to inspect every laptop that enters the country, whether or not there is anything suspicious about the computer or its owner. Rummaging through a computer's hard drive, the government says, is no different from looking through a suitcase. One federal appeals court has agreed, and a second seems ready to follow suit.......Link

I think it is time we demand privacy as a fundamental right of our citizenship."

Submission + - When Superconductivity Became Clear (to Some) (nytimes.com)

mlimber writes: The New York Times has a story in today's science section recounting the history of superconductivity — a problem which a number of notable theorists such as Einstein, Heisenberg, Bohr and Pauli attempted but failed to solve. The three men who solved it received a Nobel for their work, which is hailed as "one of the greatest achievements in physics in the second half of the 20th century."

Feed Engadget: London Underground to get half-kilometer-long LED video display (engadget.com)

Filed under: Displays, Misc. Gadgets, Transportation

Because all of the posters plastered on every single surface on the inside of the cars is clearly not enough advertising for your average subway passenger, London is poised to light up a half-kilometer-long LED display in the tunnel between Heathrow and Paddington Station. Manufactured by Canadian firm SideTrack, the simulated video system -- which is composed of 360 individual LED bars synchronized to train speeds -- will replace a static version already installed along the same Heathrow Express route, thus allowing officials to change the message without swapping out physical signage. No word yet on who the premiere advertiser will be, but this medium would seem like a good way for rental car companies to make a compelling point: "Avoid these crappy ads, rent from Avis next time."
