Optical transistor switches states by trapping a single photon

NIST Optical connections are slowly replacing wires as a means of shuffling bits in between systems—there are already plans afoot to have different components within a single system communicate via an optical connection. But, so far at least, all the processing of those bits is taking place using electrons. Yesterday’s edition of Science includes a demonstration of an all-optical transistor that can be switched between its on and off states using a single photon. Although it’s an impressive demonstration of physics, the work also indicates that we’re likely to stick with electrons for a while, given that the transistor required two lasers and a cloud of a cold atomic gas. The work relied on a cold gas of cesium atoms. These atoms have an extremely convenient property: two closely separated ground states, each with a corresponding excited state. All of these states are separated by an energy that corresponds to a specific wavelength of light, so using a laser of that wavelength allows you to shift the system into a different state.

Verizon would end “century of regulation” by killing wireline phone, says NY AG

Hurricane Sandy caused widespread damage in Fire Island, New York. Fireisland.com New York Attorney General Eric Schneiderman this week accused Verizon of trying to “depart from a century of telephone service regulation” by ending wireline telephone service in a part of Fire Island devastated by Hurricane Sandy in October, 2012. In addition, Schneiderman has accused Verizon of violating a state order by telling customers outside of Fire Island that they should accept wireless phone service instead of repairs to their landline service. He says Verizon should be fined $100, 000 per customer, per day. Verizon says it has not violated the state order, and that its offer of wireless service outside Fire Island is strictly optional. Verizon is, however, trying to gain state approval to end wireline service entirely in western Fire Island. Read 19 remaining paragraphs | Comments

Windows 8.1 to go RTM in “late August”

During its Worldwide Partner Conference in a rainy and humid Houston today, Windows CFO Tami Reller announced that Windows 8.1, the free update to Windows 8, will be made available to OEMs by “late August, ” with devices reaching the market by the holiday season. Windows 8 was released to manufacturing on August 1, 2012. Microsoft is promoting a faster release cadence across its entire range of products, and Windows 8.1 is arguably the first mass-market consumer product from the company that will benefit from this new release schedule.

Windows 8 vaults past Vista, IE10 continues to surge

Net Market Share Windows 8 passed a milestone of sorts in June, passing Windows Vista’s market share to become the third-most used version of Windows on the Internet. Internet Explorer 10 continued to show strong growth too, fueled this time by automatic updating. Google Chrome put in a strong performance, offsetting losses made earlier in the year. Its growth was to the detriment of Mozilla’s Firefox, which fell significantly. Net Market Share Net Market Share Microsoft’s browser made a slight gain, up 0.16 points to 56.15 percent (a two year high). Firefox was down 1.48 points to 19.15 percent—the lowest share the open source browser has seen for more than two years. Chrome rose 1.43 points to a 17.17 percent share. Safari was more or less unchanged, up 0.09 points to 5.55 percent. Opera lost 0.19 points for a share of 1.58 percent, a level not seen since August last year. Read 8 remaining paragraphs | Comments

Microsoft, like Google, asks secret court if it can publish data sharing total

In a new legal filing made public on Wednesday, Microsoft submitted a motion (PDF) to the notoriously secretive Foreign Intelligence Surveillance Court (FISC) saying that the company “continues to seek—to correct the misimpression, furthered by such inaccurate media reporting, that it provides the United States Government with direct access to its servers and network infrastructure and, thereby, indiscriminately discloses Microsoft users’ information to the Government.” The filing was submitted on June 19, 2013, just one day after Google’s similar motion . Like Google, Microsoft said it “seeks to report aggregate information about [Foreign Intelligence Surveillance Act] orders and [FISA Amendments Act] directives separately from all other local, state, and federal law enforcement demands.” Tech companies are presumably attempting to get FISC to allow them to release this information so that they can show there isn’t a hand-in-glove relationship between these corporations and the federal government.

Stow it no more: FAA easing ban on electronics during takeoff, landing

The words “please stow all electronic devices” may soon disappear from the scripts of flight attendants. The Federal Aviation Administration (FAA) is poised to lift its ban on the use of electronic devices aboard airline flights at elevations under 10,000 feet. It would also allow the use of e-readers, iPods, tablets, and phones in “airplane” mode even during take-offs and landings. The Wall Street Journal reports that the FAA is circulating a draft set of recommendations from an advisory panel that recommends relaxing the bans. Cell phone calls during flight would still be banned. T he report acknowledges that technology has changed dramatically since the FAA originally placed the ban on electronic devices during takeoff and landing back in the 1960s, when there were valid concerns about interference to aircraft communications from personal radios and other electronics.  The panel also admitted that having airlines each evaluate the safety of individual electronic devices before allowing them to be left on at low altitude “has become untenable.” Passengers are widely ignoring the ban already, and the FAA advisory panel’s report cited research that showed a third of airline passengers had “accidentally” left a device turned on for entire flights at least once. An FAA spokeswoman sent a statement to the Wall Street Journal that said that the FAA “recognizes consumers are intensely interested in the use of personal electronics aboard aircraft. That is why we tasked a government-industry group to examine the safety issues and the feasibility of changing the current restrictions. At the group’s request, the FAA has granted the two-month extension to complete the additional work necessary for the safety assessment.” Read on Ars Technica | Comments

Encrypted e-mail: How much annoyance will you tolerate to keep the NSA away?

Aurich Lawson In an age of smartphones and social networking, e-mail may strike many as quaint. But it remains the vehicle that millions of people use every day to send racy love letters, confidential business plans, and other communications both sender and receiver want to keep private. Following last week’s revelations of a secret program that gives the National Security Agency (NSA) access to some e-mails sent over Gmail, Hotmail, and other services—and years after it emerged that the NSA had gained access to full fiber-optic taps of raw Internet traffic—you may be wondering what you can do to keep your messages under wraps. The answer is public key encryption, and we’ll show you how to use it. The uses of asymmetry The full extent of the cooperation between the NSA and various technology companies is unclear. It will probably remain that way for the foreseeable future. For the time being, however, it seems likely that the standard cryptographic tools used to secure data “in flight”—that is to say, the SSL that protects data traveling between machines on the Internet—remain secure as long as certain best practices are used.

How OS X “Mavericks” works its power-saving magic

Apple execs talk up the new features in OS X Mavericks. At yesterday’s Worldwide Developer Conference (WWDC) keynote, Apple made some bold claims about the future of battery life in its laptops. A new 13-inch Macbook Air, for instance, should now run a full 12 hours on a single charge , up from 7 in the previous model. Assuming that testing bears out Apple’s numbers, how did the company do it? The obvious part of the answer is “Haswell”—but that turns out to be only part of the story. The power efficiency gains found in Intel’s new Haswell CPUs should provide modest gains in battery life, and such gains were widely expected. Back in January, Intel claimed that the new Haswell CPUs featured the “largest generation-to-generation battery life increase in the history of Intel” and said that the chips were the first of its architectures designed “from the ground up” for Ultrabooks and tablets. The new chips run at lower clockspeeds and at lower wattages. Less expected was the announcement of OS X 10.9 “Mavericks” and its own focus on mobile power usage. While Apple made a few comments during the keynote about the new technologies meant to enable longer battery life, more information appeared later in the day with the separate release of a Core Technology Overview (PDF) document that offers a high-level look at some of the Mavericks internals.
