Apple releases iOS 7.0.6 and 6.1.6 to patch an SSL problem

Andrew Cunningham Apple has just released iOS 7.0.6, the sixth minor update to iOS 7 . Both it and the new iOS 6.1.6 update “provide a fix for SSL connection verification,” their only documented addition. Unlike iOS 7.0.5 , which applied only to a few international iPhone 5S and 5C models, the version 7.0.6 update applies to all devices that can run iOS 7. iOS 6.1.6 applies to the iPhone 3GS and fourth-generation iPod touch. The update to iOS 6 is marginally more interesting than the iOS 7 update, just because Apple has so rarely patched old iOS versions after they’ve been replaced. The company also released version 6.1.5 for the fourth-generation iPod touch to correct a FaceTime connectivity issue. It’s possible that Apple is trying to provide critical security updates to older devices dropped by newer iOS updates, something it also does for older OS X versions for a while after they’re superseded by newer software. The next major iOS 7 update is iOS 7.1, currently in its fifth developer beta. Current rumors suggest it will be released to the public in early or mid-March, and it should include more significant fixes than the six minor updates we’ve seen since September.

Lync-Skype video chat shown for the first time, coming later this year

Ever since Microsoft bought Skype in 2011, one of the biggest questions has been how the company would integrate the voice and video messaging service with its other voice and video messaging software: Lync. Last year, the company integrated the two systems for voice calling, allowing Lync users to talk to, and see the online status of, Skype users. This year, the company will take another big step toward bringing the systems together, with cross-network video calling. The company demonstrated Lync-to-Skype video calling at its Lync Conference today. The feature will go into a limited beta in summer or fall. In addition to improved interoperability with Skype, the company is also adding native interoperability with Cisco/Tandberg video conferencing systems. Joining its existing Lync clients for Windows Phone, iPhone, iPad, and Android phones, Microsoft says that it will have a Lync client for Android tablets available in the Google Play store by the end of June.

Who needs sunlight? In Arizona, solar power never sleeps

Solana is currently the largest parabolic trough plant in the world, covering more than 1,900 acres in southern Arizona. 4 more images in gallery GILA BEND, ARIZONA—Every afternoon during the summer, millions of people across the American Southwest come home from work and switch on their air conditioners, straining the power grid in states like Arizona. Traditional solar power—although perfectly suited to the sunny climes of this region—can’t meet this demand since the surge in use peaks just as the day’s sun is disappearing. That’s why most power suppliers diversify, using electricity from different sources to meet local needs. Solar power is abundant in the middle of sunny, clear days, but energy from other sources—coal, nuclear, or hydroelectric power for example—is necessary at night or when the weather is bad. But increasingly efficient technology is allowing solar plants to contribute for a longer period of time each day and produce energy even in cloudy conditions. The key is a design that allows them to store the sun’s energy to be used later. And new facilities, such as the Solana power plant that recently came online in Gila Bend, Arizona, are increasing solar energy’s niche by producing electricity several hours after the sun sets.

Feds seek contractor to build new federal license plate reader database

According to a new job advertisement posted this week, the Department of Homeland Security (DHS) is currently seeking a contractor to build and operate a national license plate reader database. While license plate readers are on the rise by federal and local law enforcement agencies, they typically are not linked together into a one-stop shop beyond federally-funded “fusion centers,” which depend on local data. Apparently that is not enough for the feds anymore. The DHS further posted a 29-page document (PDF) outlining its requirements, including “featuring Smartphone technology based application for at least one Smartphone type, i.e. Android/iPhone/BlackBerry etc. currently in use by [Department of Homeland Security / Immigration and Customs Enforcement] allowing for license plate pictures to be taken and uploaded. Any positive matches shall return to the Smartphone an alert notification indicating to the User a positive match.” Read 3 remaining paragraphs | Comments

Skeleton from one of the earliest Americans yields its genome

The burial mound in Montana where the skeleton was found. Texas A&M University The peopling of the Americas via the Bering Sea land bridge is one of the more confusing events in recent history. Some of the earliest signs of human occupancy are actually in Chile. After that, the first distinct toolmaking culture, the Clovis people, appeared in the interior of North America, and rapidly swept across the continent. There are also indications that a separate migration occurred down the Pacific coast, possibly associated with people who had distinctive skeletal features, while the Inuit seem to be relatively recent arrivals. The sudden appearance of the Clovis toolset has caused some people to suggest that the Clovis were a distinct migration by a passage between ice sheets directly into North America’s interior. Others have even suggested that they arrived from Europe, brought by people who crossed the ice through Greenland (an idea that’s favored by a certain Bigfoot researcher ). Now, researchers have completed the genome of an individual who was buried with Clovis tools in Montana 12,500 years ago. The results suggest that the migration into North America was more unified than some thought. Although Clovis tools are relatively common at many North American sites, they’re generally not associated with skeletal remains. And there have been no distinctive skeletal features that label remains as belonging to a distinctive Clovis ethnic group. All of which makes Montana’s Anzick site exceptional: it contains remains that were placed with Clovis tools, unambiguously tagging the skeleton as belonging to this group.

Giant leap for nuclear fusion as scientists get more energy out than fuel put in

Lawrence Livermore National Laboratroy Researchers in the US have overcome a key barrier to making nuclear fusion reactors a reality. In results published in Nature , scientists have shown that they can now produce more energy than the fuel put into an experiment. The use of fusion as a source of energy remains a long way off, but the latest development is an important step toward that goal. Nuclear fusion is the process that powers the sun and billions of other stars in the universe. If mastered, it could provide an unlimited source of clean energy because the raw materials are plentiful and the operation produces no carbon emissions. During the fusion process, smaller atoms fuse into larger ones releasing huge amounts of energy. To achieve this on Earth, scientists have to create conditions similar to those at the center of the sun. This involves creating very high pressures and temperatures.

Slashdot’s new interface could kill what keeps Slashdot relevant

In the modern responsive Web Three Point Oh Internet, Slashdot stands like a thing frozen in time—it’s a coelacanth stuck incongruously in an aquarium full of more colorful fish. The technology news aggregator site has been around since 1997, making it positively ancient as websites are reckoned. More importantly, Slashdot’s long focus on open source technology news and topics has caused it to accrete a user base that tends to be extremely technical, extremely skilled, and extremely opinionated. That user base is itself the main reason why Slashdot continues to thrive, even as its throwback interface makes it look to untrained eyes like a dated relic. Though the site is frequently a source of deep and rich commentary on topics, the barrier for new users to engage in the site’s discussions is relatively high—certainly higher than, say, reddit (or even Ars). This doesn’t cause much concern to the average Slashdot user, but tech job listing site Dice.com (which bought Slashdot in September 2012, along with Sourceforge and a number of other digital properties) appears to have decided it’s time to drag Slashdot’s interface into the 21st century in order to make things comfortable for everyone—old and new users alike. And the Slashdot user base is not pleased. Read 16 remaining paragraphs | Comments

Mini-desktops are a rare bright spot in a shrinking PC industry, says Intel

Intel’s Haswell NUC sitting on top of Gigabyte’s larger (but more powerful) Brix. Intel sees mini-PCs as one of the rare PC markets where growth is possible. Andrew Cunningham The wider PC industry isn’t doing so well, and last week’s news that Sony would be selling off its VAIO business is just the latest indication. That doesn’t mean things are all bad—there’s still some growth to be found, and one area where it’s happening is in mini-desktops like Intel’s NUC or Asus’ upcoming Chromebox . Intel tells us that sales of truly tiny PCs (things near the size of the NUC, Gigabyte’s Brix Pro , or Lenovo’s M93p Tiny ) have gone from “almost zero in 2012” to over a million units in 2013. And yet, these mini desktops don’t always make sense. If you want something compact for your desk that saves you cable clutter, an all-in-one will frequently be a better option. If you want something more powerful, a more traditional micro ATX or even mini ITX PC can be purchased or built for less money, often with a greater amount of CPU and GPU power. We spoke with Lisa Graff , Vice President of Intel’s PC Client Group, to get a better idea of how these desktops are doing and who exactly is buying them. Business-friendly features in a tiny package Graff came in from the datacenter group last year to run Intel’s desktop business.  “When I came in there were a number of areas in desktop that were growing, kind of bucking the trend of some of what we’re seeing in the PC business,” Graff told Ars. “And as we started to drill in, this was one of the areas—all-in-ones were clearly a growth area, but this mini-desktop, really, the growth has been incredibly strong.” Read 11 remaining paragraphs | Comments

Biggest DDoS ever aimed at Cloudflare’s content delivery network

Ruthanne Reid A distributed denial-of-service attack targeting a client of the content delivery network Cloudflare reached new highs in malicious traffic today , striking at the company’s data centers in Europe and the US. According to a Twitter post by Cloudflare CEO Matthew Prince, the full volume of the attack exceeded 400 gigabits per second—making it the largest DDoS attack ever recorded. The attack used Network Time Protocol (NTP) reflection , the same technique used in recent attacks against gaming sites by a group called DERP Trolling. NTP is used to synchronize the time settings on computers across the Internet. The attack made fraudulent synchronization requests to NTP servers that caused them to send a flood of replies back at the targeted sites. Reflection attacks have been a mainstay of DDoS tools and botnets, but the use of NTP in such attacks is relatively new. Last year’s attack on Spamhaus , which previously set the record for the largest DDoS ever, used a Domain Name Service (DNS) protocol attack—a much more common approach that takes advantage of the Internet’s directory service, forging requests for DNS lookups from the intended target and sending them to scores of open DNS servers. The size of the traffic directed back at the target from these requests far exceeds the size of the requests sent to the DNS servers, which is why the technique is often called a DNS amplification attack.

11 high school students expelled for keylogging teachers’ computers

Corona del Mar sits on an idyllic part of the Orange County coastline. Mark Weston A hacking scandal involving keyloggers and electronic grade-changing at a high school in Newport Beach, a well-to-do area of Southern California, has resulted in the expulsion of 11 students. The Orange County Register reported Wednesday that six of those students had already left the district, but five had been transferred to another local school. “The Board’s action imposes discipline upon these students for the maximum allowed by the Education Code for what occurred at Corona del Mar High School,” Laura Boss, the Newport Mesa Unified School District spokesperson wrote in a statement on Wednesday. US News and World Report ranked the high school in question as the 46 th best within California. Read 23 remaining paragraphs | Comments
