2013 iMac teardowns reveal SSD slots, soldered-in CPU in the 21.5” model

All iMacs now leave you an empty PCIe SSD slot to use if you don’t go in for the Fusion Drive or SSD upgrade, but it’s still hard to get at. iFixit Just one day after Apple quietly refreshed its iMac lineup with Intel’s new Haswell processors, the teardown artists at iFixit have pulled both the 21.5-inch and 27-inch models apart to see what makes them tick. One of our chief complaints about last year’s 21.5-inch iMac was how difficult it was to upgrade, and that remains true of this year’s model. You can still access the computer’s two RAM slots if you’re brave enough to attempt the teardown process (which includes tearing apart and replacing some foam padding), and Apple has included an empty PCIe slot on the base model where last year’s model only had an empty spot on the system board. However, the low-end iMac’s use of Intel’s Iris Pro 5200 integrated GPUs means that it uses one of Intel’s R-series CPUs, and those CPUs only come in a soldered-on ball-grid array (BGA) package. The 27-inch model proves a bit easier to upgrade: it still has four user-accessible RAM slots, still leaves people who opt out of the Fusion Drive or SSD upgrades an empty PCIe slot to use, and still uses a socketed Intel CPU for those of you who want to take the trouble to upgrade that component yourselves after the fact. Both the 21.5-inch and 27-inch iMacs were also confirmed to be using triple-antenna (3×3:3) 802.11ac configurations, meaning the iMacs will be capable of the standard’s maximum theoretical transfer speed of 1.3Gbps where the 2013 MacBook Airs used a two-antenna setup capable of 867Mbps speeds.

Nvidia seeks peace with Linux, pledges help on open source driver

Will Nvidia give Linus a reason to lower his finger? aaltouniversityace Few companies have been the target of as much criticism in the Linux community as Nvidia. Linus Torvalds himself last year called Nvidia the ” single worst company ” Linux developers have ever worked with, giving the company his middle finger in a public talk. Nvidia is now trying to get on Linux developers’ good side. Yesterday, Nvidia’s Andy Ritger e-mailed developers of Nouveau, an open source driver for Nvidia cards that is built by reverse engineering Nvidia’s proprietary drivers. Ritger wrote that “NVIDIA is releasing public documentation on certain aspects of our GPUs, with the intent to address areas that impact the out-of-the-box usability of NVIDIA GPUs with Nouveau. We intend to provide more documentation over time, and guidance in additional areas as we are able.” The first step was releasing documentation of the Device Control Block (DCB) layout in Nvidia’s VBIOS, describing the board’s topology and display connectors. Ritger continued: Read 5 remaining paragraphs | Comments

Blackberry warns of near-$1 billion loss this quarter

Blackberry released a statement on Friday saying that it expects to report an operating loss of almost $1 billion in the coming days. According to The Wall Street Journal , Blackberry overestimated the number of new phones it would sell and is facing an “inventory charge of as much as $960 million and a restructuring charge of $72 million.” Specifically, the company said that it would likely report a loss of $950 million to $995 million for the second quarter. Earlier this week we reported that Blackberry was planning to lay off up to 40 percent of its employees, taking the company from 12, 700 full-time employees to about 7, 620 employees. The WSJ reported today that 4, 500 people will be laid off, lower than earlier estimates. (Is that a silver lining we see?) The Canadian company also reported today that it only sold 3.7 million smartphones in the last quarter, most of which were older phones. To stem the bleeding, Blackberry said that going forward, its “smartphone portfolio will transition from 6 devices to 4; focusing on enterprise and prosumer-centric devices, including 2 high-end devices and 2 entry-level devices.” As Quartz writer Christopher Mims wrote , it’s probably too late for Blackberry to turn around its share of the enterprise market given the latest moves made by Apple and Samsung to get their hardware into the hands of businesspeople.

The new lifecycle of your old iPhone

Clifford Joseph Kozak After handling the entire digital expression of your life for one, two, or more years, the most mercenary and practical end that a smartphone can meet is to be sold off secondhand. Wheeling and dealing with used personal electronics is not a new business, but in the last few years, it’s been writ very large with the glut of tiny hand-computers we’re all using lately. Where those devices go after you sell them into wanting hands (Gazelle and NextWorth are two services that make their business on these transactions) has shifted a bit over the years. In the early days of the iPhone, companies were built on the activity of breaking down old iPhones into parts for repairing those still in use (or so some of the shadier companies claimed). Per a report in the New York Times back in 2008, one company named PCS Wireless claimed that 94-95 percent of the second-hand phones it obtained were broken down into parts. The source claimed at the time that the screens alone could fetch $200. Read 12 remaining paragraphs | Comments

Intel’s Atom CPUs finally get serious with the new Bay Trail architecture

Intel News from a certain other company has overshadowed the 2013 Intel Developer Forum a bit this week, but Intel is hardly sitting still. For well over a year now, the company has been intensifying its efforts in the mobile space, first with Android phones and later with both Windows and Android tablets. The chips the company has been using to make these strides into mobile have all used the Atom branding, which has come a long way since its inclusion in the low-rent netbooks of years past. Chips like Clover Trail and Clover Trail+ have proven that an Intel phone’s battery life can hang with ARM chips from companies like Qualcomm and Nvidia, even if their performance sometimes leaves something to be desired. Now, Intel is ready to take the next step. We’ve talked about its next-generation Atom system-on-a-chip (SoC) for tablets (codenamed Bay Trail ) before, and at IDF this week the company finally announced specific Bay Trail SKUs and devices that will include the chips when they ship later this year.

Fingerprints as passwords: New iPhone Touch ID gets mixed security verdict (Updated)

Chad Miller Of all the new features of Apple’s new iPhone 5S , few have drawn more attention than the built-in fingerprint scanner known as Touch ID. Apple billed it as an “innovative way to simply and securely unlock your phone with just the touch of a finger.” More breathless accounts were calling it a potential ” death knell for passwords ” or using similarly overblown phrases . Until the new phones are in the hands of skilled hackers and security consultants, we won’t know for sure if Touch ID represents a step forward from the security and privacy offered by today’s iPhones. I spent several hours parsing the limited number of details provided by Apple and speaking to software and security engineers. I found evidence both supporting and undermining the case that the fingerprint readers are an improvement. The thoughts that follow aren’t intended to be a final verdict—the proof won’t be delivered until we see how the feature works in the real world. The pros I’ll start with the encouraging evidence. Apple said Touch ID is powered by a laser-cut sapphire crystal and a capacitive touch sensor that is able to take a high-resolution image based on the sub-epidermal layers of a user’s skin. While not definitive, this detail suggests Apple engineers may have designed a system that is not susceptible to casual attacks. If the scans probe deeply enough, for instance, Touch ID probably wouldn’t be tricked by the type of clones that are generated from smudges pulled off a door knob or computer monitor. In 2008, hackers demonstrated just how easy it was to create such clones when they published more than 4, 000 pieces of plastic film containing the fingerprint of a German politician who supported the mandatory collection of citizens’ unique physical characteristics. By slipping the foil over their own fingers, critics were able to mimic then-Interior Minister Wolfgang Schauble’s fingerprint when touching certain types of biometric readers.

Virtual Perfection: Why 8K resolution per eye isn’t enough for perfect VR

So you want me to squeeze two 8K displays into this space? No problem! Give me a decade or so… “Without going into a rant, the term ‘Retina Display’ is garbage, I think.” Palmer Luckey, the founder and creator of the Oculus Rift, is a bit of a perfectionist when it comes to creating the best possible virtual reality experience. So when our recent interview turned toward the ideal future for a head-mounted display—a theoretical “perfect” device that delivers everything he could ever dream of—he did go on a little rant about what we currently consider “indistinguishable” pixels. “There is a point where you can no longer distinguish individual pixels, but that does not mean that you cannot distinguish greater detail, ” he said. “You can still see aliasing on lines on a retina display. You can’t pick out the pixels, but you can still see the aliasing. Let’s say you want to have an image of a piece of hair on the screen. You can’t make it real-size… it would still look jaggy and terrible. There’s a difference between where you can’t see pixels and where you can’t make improvements.” Read 13 remaining paragraphs | Comments

Sudden spike of Tor users likely caused by one “massive” botnet

Tor Project Researchers have found a new theory to explain the sudden spike in computers using the Tor anonymity network: a massive botnet that was recently updated to use Tor to communicate with its mothership. Mevade.A, a network of infected computers dating back to at least 2009, has mainly used standard Web-based protocols to send and receive data to command and control (C&C) servers, according to researchers at security firm Fox-IT. Around the same time that Tor Project leaders began observing an unexplained doubling in Tor clients , Mevade overhauled its communication mechanism to use anonymized Tor addresses ending in .onion. In the week that has passed since Tor reported the uptick, the number of users has continued to mushroom. “The botnet appears to be massive in size as well as very widespread, ” a Fox-IT researcher wrote in a blog post published Thursday . “Even prior to the switch to Tor, it consisted of tens of thousands of confirmed infections within a limited amount of networks. When these numbers are extrapolated on a per country and global scale, these are definitely in the same ballpark as the Tor users increase.” Read 3 remaining paragraphs | Comments

Lenovo’s new Yoga 2 Pro has the same flexible hinge, 3200×1800 display

The new Yoga 2 Pro is a high-res follow-up to one of the better convertible laptop designs on the market. Lenovo The original IdeaPad Yoga  was one of our favorite early convertible laptops, not least because the “convertible” part didn’t ruin the “laptop” part. Its many contortions were also genuinely useful, even if the weight and exposed keyboard made it a bit too awkward to use as a dedicated tablet. We got a belated 11-inch version of the original Yoga a bit earlier this year, but today at IFA, Lenovo has formally announced a pair of true sequels that look to improve the design without radically altering its formula. From the folding hinge to the bright “clementine orange” color, the Yoga 2 Pro is very much a successor to the first Yoga. It loses some weight and some thickness, dropping to 0.61 inches thick and 3.06 pounds from the 0.68 inches and 3.4 pounds of the original. It also includes Intel’s new Haswell processors (and its new integrated GPUs—there’s no dedicated graphics option available), but the biggest upgrade is the 13.3-inch 3200×1800 touchscreen. At 276 PPI, this is a substantial upgrade over the 1600×900 display of the original, though the (included) Windows 8.1 Pro can have some issues with high-PPI displays . Like the older Yoga, the new one is indistinguishable from a regular laptop most of the time. Lenovo The other specs are a mixed bag—you’ve got 8GB of DDR3L, standard 128, 256, and 512GB SSDs, a backlit keyboard, and Bluetooth 4.0 (all good), but there’s only one USB 3.0 port (the other is USB 2.0) and a frustratingly low-end 2.4GHz-only 802.11n Wi-Fi adapter. We understand laptops that don’t ship with 802.11ac yet, since that’s still a new standard and many people won’t have upgraded to a compatible router just yet. But to ship a high-end laptop without dual-band 802.11n seems like a seriously missed opportunity. The laptop also promises around six hours of battery life, which would have been on the low end of average for an Ivy Bridge Ultrabook but is a bit disappointing for a Haswell model.

Balky carriers and slow OEMs step aside: Google is defragging Android

Ron Amadeo Android 4.3 was released to Nexus devices a little over a month ago, but, as is usual with Android updates, it’s taking much longer to roll out the general public. Right now, a little over six percent of Android users have the latest version. And if you pay attention to the various Android forums out there, you may have noticed something: no one cares. 4.3’s headline features are a new camera UI, restricted user profiles, and support for new versions of Bluetooth and OpenGL ES. Other than the camera, these are all extremely dull, low-level enhancements. It’s not that Google is out of ideas, or the Android team is slowing down. Google has purposefully made every effort to make Android OS updates as boring as possible. Why make boring updates? Because getting Samsung and the other OEMs to actually update their devices to the latest version of Android is extremely difficult. By the time the OEMs get the new version, port their skins over, ship a build to carriers, and the carriers finally push out the OTA update, many months pass. If the device isn’t popular enough, this process doesn’t happen at all. Updating a phone is a massive project involving several companies, none of which seem to be very committed to the process or in much of a hurry to get it done.
