Physicists Attempting To Test ‘Time Crystals’

ceview writes “This story at Wired seems to have lots of people a bit confused: ‘In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of “time crystals” — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. … [A] Berkeley-led team will attempt to build a time crystal by injecting 100 calcium ions into a small chamber surrounded by electrodes. The electric field generated by the electrodes will corral the ions in a “trap” 100 microns wide, or roughly the width of a human hair. The scientists must precisely calibrate the electrodes to smooth out the field. Because like charges repel, the ions will space themselves evenly around the outer edge of the trap, forming a crystalline ring.’ The experimental set up is incredibly delicate (Bose Einstein Condensate), so it implies this perpetual motion effect can’t really be used to extract energy. What is your take on it? It’s unlike to upend anything, as the article suggests, because at a quantum level things behave weirdly at the best of times. The heavy details are available at the arXiv.”

Pirates of the Caribbean: the Pirate Bay Moves To Island of Sint Maarten

The Internet

New submitter coolnumbr12 writes “For the second time in a week, The Pirate Bay has found a new home for its popular torrent website. A complaint issued Tuesday by Swedish prosecutors threated the Icelandic domain, forcing the file-sharing pirates to take harbor in the Caribbean island of Sint Maarten with a new .sx domain name. ‘Control of the island, which has just 78,000 residents, is split between France and the Netherlands. Around 41,000 live on the Dutch side and 37,000 on the French. … Even if the court grants the prosecutor’s request it remains to be seen how effective any seizures will be. Time and again the BitTorrent site has responded by relocating to new domains.’”

Study: Limiting Bidding On Spectrum Could Cost Billions

April 30th, 2013 04:18 admin View Comments

AT&T

itwbennett writes “According to a study (PDF) by the Georgetown Center for Business and Public Policy, restricting the ability of Verizon Wireless and AT&T to bid in upcoming spectrum auctions would drive down the bidding during the auction, and could cost the U.S. treasury as much as $12 billion. Even a partial restriction of bids by Verizon and AT&T could have a significant impact on auction revenues, said Douglas Holtz-Eakin, a co-author of the Georgetown study. Matt Wood, policy director at digital rights group Free Press, fired back, saying ‘No one is talking about completely barring AT&T and Verizon from the incentive auction. Sensible people are talking about making sure that more than two companies have a chance at obtaining spectrum. The fact that these duopolists hired economists to parrot the companies’ own talking points isn’t really that newsworthy.’”

OpenStreetMap Adds Easier Reporting of Map Problems

April 30th, 2013 04:19 admin View Comments

The Internet

An anonymous reader writes “OpenStreetMap recently topped one million registered users. Now they are trying to make the barrier to entry for contributing to the project even lower. A new ‘notes’ feature, announced on the project’s blog, allows anonymous users to submit bug reports which will alert mappers in the area to incorrect or incomplete map information. The feature also allows for commenting on notes, potentially enabling two-way communication between a mapper and a bug reporter if more information is needed.”

FSF Certifies Atheros-Based ThinkPenguin 802.11 N USB Adapter

GNU is Not Unix

gnujoshua writes “You may recall that last Fall, the LulzBot AO-100 3D printer was awarded the use of the Free Software Foundation’s Respects Your Freedom certification mark. Today, the FSF announced certification of the ThinkPenguin TPE-N150USB, Wireless N USB Adapter, which uses the Atheros ARAR9271 chip. The FSF’s RYF certification requirements are focused on the software (not the hardware designs) of a product, which in this case was primarily the device firmware and ath9k-htc module in the Linux-libre kernel. (Disclosure: I work for the FSF.) There’s also a cool story that is within this story… which is that the firmware for the Atheros AR9271 chipset was released as a result of a small device seller (ThinkPenguin) striking a deal with a large electronic device manufacturer (Qualcomm Atheros) to build a WLAN USB adapter that shipped with 100% free software firmware. This deal was possible largely because two motivated Qualcomm Atheros employees, Adrian Chadd and Luis Rodriguez, made the internal-push to get the firmware released as free software.”
