The cops are tracking my car—and yours

Aurich Lawson OAKLAND, CA—The last time the Oakland Police Department (OPD) saw me was on May 6, 2013 at 6:38:25pm. My car was at the corner of Mandana Blvd. and Grand Ave. , just blocks away from the apartment that my wife and I moved out of about a month earlier. It’s an intersection I drive through fairly frequently even now, and the OPD’s own license plate reader (LPR) data bears that out. One of its LPRs—Unit 1825—captured my car passing through that intersection twice between late April 2013 and early May 2013. I have no criminal record, have committed no crime, and am not (as far as I know) under investigation by the OPD or any law enforcement agency. Since I first moved to Oakland in 2005, I’ve been pulled over by the OPD exactly once—for accidentally not making a complete stop while making a right-hand turn at a red light—four years ago. Nevertheless, the OPD’s LPR system captured my car 13 times between April 29, 2012 and May 6, 2013 at various points around the city, and it retained that data. My car is neither wanted nor stolen. The OPD has no warrant on me, no probable cause, and no reasonable suspicion of wrongdoing, yet it watches where I go. Is that a problem? Read 73 remaining paragraphs | Comments

ISS spacewalk aborted when water begins to fill astronaut’s suit

American Chris Cassidy and Italian Luca Parmitano were forced to call off this morning’s planned spacewalk outside the International Space Station when Parmitano suddenly reported that there was water inside of his suit helmet. “My head is really wet and I have a feeling it’s increasing, ” he radioed about an hour into the spacewalk. Video of the aborted EVA, starting with the discovery of the water. The call to terminate EVA comes at 12:45. Station airlock opens at 44:48. The EVA, designated EVA-23, was one of the ones that Ars watched astronauts Cassidy and Parmitano train for late last year. That was during our visit to NASA’s Neutral Buoyancy Laboratory , the giant swimming pool where NASA simulates spacewalks in microgravity. According to NASASpaceFlight’s recounting of events , Parmitano was in the process of running data cabling to connect the as-yet-unlaunched Russian Nauka module when the water began to make itself apparent. The quantity of liquid in Parmitano’s helmet rapidly increased, with Parmitano noting that it had begun to enter his eyes, nose, and mouth. Read 6 remaining paragraphs | Comments

USB 3.0 continues to steal Thunderbolt’s thunder

PCs that use Thunderbolt are rare, and they’re getting rarer. Chris Foresman For Thunderbolt fans hoping that the high-speed interface will catch on, we’ve got more bad news: an Acer representative talking to CNET has said that the company has no plans to support Thunderbolt in its PCs this year. Acer’s Aspire S5 Ultrabook was one of the few Windows laptops to include Thunderbolt support when it was introduced in early 2012. “We’re really focusing on USB 3.0—it’s an excellent alternative to Thunderbolt, ” said the Acer spokesperson. “It’s less expensive, offers comparable bandwidth, charging for devices such as mobile phones, and has a large installed base of accessories and peripherals.” By itself, the news of one company distancing itself from Thunderbolt might not be a big deal, but this is just another example of the trouble that Thunderbolt faces two-and-a-half years after its public introduction in the 2011 MacBook Pro. A Newegg search reveals a handful of high-end desktop motherboards that support it (five boards, all above $150), but the complete list of non-Apple prebuilt systems that have ever supported the interface is pretty short .

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.

Mass-login attack on Nintendo fan site hijacks 24,000 accounts

Almost 24, 000 user accounts on Nintendo’s main fan site have been hijacked in a sustained mass-login attack that began early last month, the company said. The wave of attacks on Club Nintendo exposed personal information associated with 23, 926 compromised accounts, including users’ real names, addresses, phone numbers and e-mail addresses, according to a press release Nintendo issued over the weekend. The campaign began on June 9 and attempted more than 15.5 million logins over the following month. Attackers likely relied on a list of login credentials taken from a site unrelated to Nintendo. Club Nintendo offers rewards to Nintendo customers in exchange for having them register their products, answer surveys, and provide personal data. The site operates internationally and has about four million users in Japan, the primary region of most affected users. Things came to a head on July 2, when the wave of logins crested. By Friday, July 5, Nintendo had reset passwords on the site. Read 2 remaining paragraphs | Comments

Can Apple read your iMessages? Ars deciphers “end-to-end” crypto claims

Aurich Lawson Ever since the National Security Agency’s secret surveillance program came to light three weeks ago, implicated companies have issued carefully worded statements denying that government snoops have direct or wholesale access to e-mail and other sensitive customer data. The most strenuous denial came 10 days ago, when Apple said it took pains to protect personal information stored on its servers , in many cases by not collecting it in the first place. “For example, conversations which take place over iMessage and FaceTime are protected by end-to-end encryption so no one but the sender and receiver can see or read them,” company officials wrote . “Apple cannot decrypt that data. Similarly, we do not store data related to customers’ location, Map searches or Siri requests in any identifiable form.” Some cryptographers and civil liberties advocates have chafed at the claim that even Apple is unable to bypass the end-to-end encryption protecting them. After all, Apple controls the password-based authentication system that locks and unlocks customer data. More subtly, but no less important, cryptographic protections are highly nuanced things that involve huge numbers of moving parts. Choices about the types of keys that are used, the ways they’re distributed, and the specific data that is and isn’t encrypted have a huge effect on precisely what data is and isn’t protected and under what circumstances.

Hands-on with Windows 8.1 Preview: Windows 8 done right

Late last month, Microsoft announced a raft of interface changes that Windows 8.1 would introduce. We’ve been giving them a spin. As you might guess from the name, Windows 8.1 is an update to (and improvement on) Windows 8. The new user interface introduced in that operating system—the Start screen, touch-friendly “Modern” apps, the charms bar—is retained in Windows 8.1. What we see is a refinement and streamlining of these concepts. The new Start screen is a pleasing evolution of the old one. The differences are visible as soon as you log in. In 8.1, the Start screen offers a lot more flexibility over layout and tile sizing. By default, the Weather tile takes advantage of this, using a new double-height tile size to show the forecasts for both today and tomorrow, in addition to the current conditions.

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.

Chinese supercomputer destroys speed record and will get much faster

Lights on the Tianhe-2 supercomputer change color depending on the power load. Jack Dongarra A Chinese supercomputer known as Tianhe-2 has been measured at speeds of 30.65 petaflops, or 74 percent faster than the current holder of the world’s-fastest-supercomputer title. The speed is remarkable partly because the Intel-based Tianhe-2 (also known as Milkyway-2) wasn’t even running at full capacity during testing. A five-hour Linpack test using 14,336 out of 16,000 compute nodes, or 90 percent of the machine, clocked in at the aforementioned 30.65 petaflops. (A petaflop is one quadrillion floating point operations per second, or a million billion.) Linpack benchmarks are used to rank the Top 500 supercomputers in the world . The Top 500 list’s current champion is Titan, a US system that hit 17.59 petaflops. Tianhe-2 achieved 1.935 gigaflops per watt, which is slightly less efficient than Titan’s 2.143 gigaflops per watt. Tianhe-2’s numbers were revealed this week in a paper by University of Tennessee professor Jack Dongarra, who created the Linpack benchmarks and helps compile the bi-annual Top 500 list. Dongarra’s paper doesn’t say whether Tianhe-2’s Linpack measurement was officially submitted for inclusion in the Top 500 list. Ars has asked him if the measurement will put Tianhe-2 on top when the next list is released, but we haven’t heard back yet. In any case, the new Top 500 rankings will be unveiled on June 17.
