MediaTek’s Octa-Core Processor Tested
Comments Off on MediaTek’s Octa-Core Processor Tested
MediaTek raised quite a few eyebrows earlier this year when it announced it would build the world’s first proper ARM octa-core, not a big.LITTLE design. The MT6592 has now popped up on a Chinese site, with the first Antutu results.
It scored 25,496, which places it behind the 1.7GHz Snapdragon in the HTC One, but it’s still a lot faster than the Nexus 4’s Qualcomm APQ8064, although throttling may have something to do with that. The score seems too high, but not long after the results emerged, a number of mobile sites started talking about disappointing results, claiming that MediaTek’s octa-core was somehow supposed to end up on a par with Samsung’s latest Exynos 5 big.LITTLE chip and the Qualcomm 800.
This of course is utter rubbish and FUD of the highest order.
The 28nm MT6592 is indeed an octa-core, but it has eight A7 cores, not a combo of A15 and A7 cores. The A7 is about one fifth of the die area of an A15 and according to ARM it consumes one quarter to one fifth of the power, making such comparisons asinine. In other words, MediaTek’s octa-core should end up a lot smaller and cheaper than a quad A15, maybe even a quad A12. That is why we find the 25,496 result hard to believe – it should be less, not more. For example, the Tegra 4 on Shield hits about 36,000, yet it’s a much bigger chip, on a device with more RAM.
The benchmarked chip ran at 1.7GHz, but MediaTek said the MT6592 should have no trouble hitting 2GHz, which could make it faster than a Snapdragon 600. What’s more, the tested device featured 1GB of RAM, 720p display and a Mali-450 GPU, so it is clearly not high-end.
However, the big problem for MediaTek’s curious new SoC is the sheer number of cores. Most apps simply can’t put them to good use and unless MediaTek has a clever trick up its sleeve, the chip might not be nearly as fast in real world applications. It does look promising in benchmarks, though.
Amazon Debuts Cloud-based Transcoding Service
Comments Off on Amazon Debuts Cloud-based Transcoding Service
Amazon Web Services has rolled out the option to use its Elastic Transcoder for audio-only conversions.
Amazon Elastic Transcoder was developed to offer an easy and low-cost way to convert media files from their source format into versions that will play on devices like smartphones, tablets and PCs.
The new feature lets anyone use Amazon Elastic Transcoder to convert audio-only content like music or podcasts from one format to another. Users can also strip out the audio tracks from video files and create audio-only streams. An option that, for example, can be used to create podcasts from video originals that are compatible with iOS applications that require an audio-only HTTP Live Streaming (HLS) file set, Amazon said.
The output from Elastic Transcoder is two-channel AAC, MP3 or Vorbis. Metadata like track name, artist, genre and album art is included in the output file and users can also specify replacement or additional album art.
Users of the service pay for the length of their converted content. For audio-only transcoding, prices start at $0.0045 per minute. That compares to the video version, which costs from $0.015 per minute for standard definition content and $0.03 per minute for high-definition clips, according to Amazon’s website.
For users who want to try out the service, the AWS Free Tier offers up to 20 minutes of free audio output per month. The service was announced for video in January and is still tagged as a beta.
Apple Hacked

Comments Off on Apple Hacked
A group of German hackers claimed to have successfully breached the iPhone fingerprint scanner on Sunday, just two days after Apple Inc debuted the technology that it promises will better protect devices from criminals and snoopers seeking access.
If the claim is verified, it will be embarrassing for Apple which is betting on the scanner to set its smartphone apart from new models of Samsung Electronics Co Ltd and others running the Android operating system of Google Inc.
Two prominent iPhone security experts told Reuters that they believed the German group, known as the Chaos Computing Club, or CCC, had succeeded in defeating Apple’s Touch ID, though they had not personally replicated the work.
One of them, Charlie Miller, co-author of the iOS Hacker’s Handbook, described the work as “a complete break” of Touch ID security. “It certainly opens up a new possibility for attackers.”
Apple representatives did not respond to requests for comment.
CCC, one the world’s largest and most respected hacking groups, posted a video on its website that appeared to show somebody accessing an iPhone 5S with a fabricated print. The site described how members of its biometrics team had cracked the new fingerprint reader, one of the few major high-tech features added to the latest version of the iPhone.
The group said they targeted Touch ID to knock down reports about its “marvels,” which suggested it would be difficult to crack.
“Fingerprints should not be used to secure anything. You leave them everywhere, and it is far too easy to make fake fingers out of lifted prints,” a hacker named Starbug was quoted as saying on the CCC’s site.
The group said it defeated Touch ID by photographing the fingerprint of an iPhone’s user, then printing it on to a transparent sheet, which it used to create a mold for a “fake finger.”
CCC said similar processes have been used to crack “the vast majority” of fingerprint sensors on the market.
“I think it’s legit,” said Dino Dai Zovi,” another co-author of the iOS Hacker’s Handbook. “The CCC doesn’t fool around or over-hype, especially when they are trying to make a political point.”
Touch ID, which was only introduced on the top-of-the-line iPhone 5S, lets users unlock their devices or make purchases on iTunes by simply pressing their finger on the home button. It uses a sapphire crystal sensor embedded in the button.
Data used for verification is encrypted and stored in a secure enclave of the phone’s A7 processor chip.
Two security experts who sponsored an impromptu competition offering cash and other prizes to the first hackers who cracked the iPhone said they had reviewed the information posted on the CCC website, but wanted more documentation.
“We are simply awaiting a full video documentation and walk through of the process that they have claimed,” said mobile security researcher Nick DePetrillo, who started the contest with another security expert, Robert Graham. “When they deliver that video we will review it.”
The two of them each put up $100 toward a prize for the contest winner, then set up a website inviting others to contribute. While the booty now includes more than $13,000 in cash, it was not clear that the CCC would receive the full payout, even if DePetrillo and Graham declared them winners.
HP To Support The iPad

Comments Off on HP To Support The iPad
Is your iPad out of warranty? Hewlett-Packard to the rescue.
HP updated its SmartFriend support service and will now troubleshoot problems with Windows, Android, Chrome OS, OS X and iOS products, according to a fact sheet describing the service.
“HP is expanding its HP SmartFriend service to provide 1:1 expert support for any brand of PC or tablet,” the company said. The plan previously supported PCs from HP and other vendors, as well as Macs.
Users can avail of the service to address general hardware, software and malware issues. HP says its agents can “remove viruses, improve PC performance, solve software errors, and connect devices to a wireless network with enhanced security.” The support is provided by phone or over the Internet, so don’t expect a technician to trot in and fix your iPad in person. But HP notes it can save you from driving to a store.
Unlike Best Buy’s Geek Squad service, HP’s service does not include hardware repairs. It can be tricky to change the battery or storage in tablets, so for iPads, the Genius Bars at Apple Stores may still be the best option for some repairs.
HP didn’t immediately comment on exactly what support it will provide for the iPad. HP printers offer wireless printing from iPads and iPhones. HP sells primarily Windows PCs and Android tablets, though on last Thursday it announced the Pavilion 14 laptop with Google’s Chrome OS.
While SmartFriend includes support for iOS devices, the service seems focused mainly on Windows products. Its technicians include “Microsoft Application Trainers, Microsoft Product Specialists, A+/MCP/MCSE Certified Professionals, Network Administrators and HTML Developers,” according to the fact sheet.
The service starts at US$9.99 per month and users can sign up for a pre-paid, monthly or yearly support plan. A “Complete Plan” supports two devices, while a “Family Plan” supports up to four devices.
AMD’s Richland Shows Up
Kaveri is coming in a few months, but before it ships AMD will apparently spice up the Richland line-up with a few low-power parts.
CPU World has come across an interesting listing, which points to two new 45W chips, the A8-6500T and the A10-6700T. Both are quads with 4MB of cache. The A8-6500T is clocked at 2.1GHz and can hit 3.1GHz on Turbo, while the A10-6700T’s base clock is 2.5GHz and it maxes out at 3500MHz.
The prices are $108 and $155 for the A8 and A10 respectively, which doesn’t sound too bad although they are still significantly pricier than regular FM2 parts.
HTC Cutting US Jobs

Comments Off on HTC Cutting US Jobs
In another sign of trouble at HTC, the Taiwan-based mobile device maker began downsizing its U.S. operations on Friday, eliminating an undisclosed number of staff.
The move is meant to “streamline and optimize” the company’s U.S. organization “after several years of aggressive growth,” HTC said in a Monday email. A company spokeswoman declined to specify how many employees would be affected.
“However, to achieve our long-term goals as a business and return maximum value to our shareholders, this is a necessary step to drive ongoing innovation,” the company said.
HTC has been facing a difficult year on weak earnings that have sent its stock price tumbling. In the second quarter, its net profit plummeted 83 percent year-over-year, despite strong reviews for its flagship smartphone, the HTC One.
The weak financials are major change from only a couple years ago when HTC was riding high selling Android smartphones in the U.S. But starting in late 2011, the company’s net profit has sagged on increased competition from Samsung and Apple.
To recover, HTC has focused on building up its “One” smartphone brand. In addition, the company has expanded its China presence, and in August launched a new marketing campaign that’s enlisted Hollywood actor Robert Downey Jr.
While the company has largely focused selling high-end handsets, in July HTC said it was planning on selling more mid-tier and entry level phones to regain market share. The new phones will launch at end of the third quarter or early fourth quarter.
But the company’s troubles go beyond issues with smartphone sales and marketing. In September, Taiwanese authorities arrested three HTC employees for allegedly stealing company secrets. One of the employees arrested was Thomas Chien, HTC’s vice president of product design.
HTC has declined to offer further details on the case.
AMD’s Kaveri Coming In Q4
AMD really needs to make up its mind and figure out how it interprets its own roadmaps. A few weeks ago the company said desktop Kaveri parts should hit the channel in mid-February 2014. The original plan called for a launch in late 2013, but AMD insists the chip was not delayed.
Now though, it told Computerbase.de that the first desktop chips will indeed appear in late 2013 rather than 2014, while mobile chips will be showcased at CES 2014 and they will launch in late Q1 or early Q2 2014.
As we reported earlier, the first FM2+ boards are already showing up on the market, but at this point it’s hard to say when Kaveri desktop APUs will actually be available. The most logical explanation is that they will be announced sometime in Q4, with retail availability coming some two months later.
Kaveri is a much bigger deal than Richland, which was basically Trinity done right. Kaveri is based on new Steamroller cores, it packs GCN graphics and it’s a 28nm part. It is expected to deliver a significant IPC boost over Piledriver-based chips, but we don’t have any exact numbers to report.
Dell Bets On Windows 8
Demand for Windows 8 may be still somewhat lukewarm, but Dell is maintaining its stance that it is the best operating system for business tablets and plans to roll out more Windows 8-based products later this year, according to a senior executive at the computer maker.
“Our Windows tablets are more secure and easier to manage than Android-based products and iOS-based products [because Windows is] on our tablets,” said Jeff Clarke, vice chairman and president of global operations at Dell. “And we are not going to change that.”
Windows-based devices accounted for just 4.5% of tablet sales in this year’s second quarter, according to research firm IDC. In comparison, Android-based devices had 62.6% of the tablet market and Apple’s iPad had 32.5%.
The slow adoption of Windows 8 tablets is partly due to their high prices, and to the operating system’s lack of mobile apps, analysts say. Windows 8 has also received mixed reviews, with some people citing its lack of a Start button in the desktop mode as a major problem.
But Dell expects demand for Windows 8 devices to pick up with the availability of Windows 8.1, which Microsoft will release in October.
Is The Tesla Hackable?
It’s the curse of the connected car once it’s linked to the Internet, it’s, well, on the Internet. In the case of the Tesla Model S, this means that mischievous hackers could, in theory, control some functions of the vehicle and even snoop without the owner’s knowledge.
Tesla offers Android and iPhone apps for Model S owners, which can be used to check the vehicle’s battery, track its location and status, and tweak several other settings, like climate control and the sunroof. It can also be used to unlock the doors on the Model S.
Dell senior engineer George Reese says the REST API used by Tesla to provide access for Android and iPhone apps has several fairly serious security flaws, which could offer a way in for unscrupulous hackers.
According to an article written by Reese for O’Reilly, Tesla appears to have broken from accepted best practice when designing the API for the Model S.
“It’s flawed in a way that makes no sense. Tesla ignored most conventions around API authentication and wrote their own. As much as I talk about the downsides to OAuth (a standard for authenticating consumers of REST APIs–Twitter uses it), this scenario is one that screams for its use,” he wrote.
However, Reese notes, this is merely a potential attack vector, not one that could be immediately exploited. That said, a compromised website particularly one designed to provide “value-added services” via the API to Tesla drivers could prove highly damaging.
“I can … honk their horns, flash their lights, and open and close the sunroof. While none of this is catastrophic, it can certainly be surprising and distracting while someone is driving,” Reese wrote.
Automotive hacking has been posited by experts for some time, and several presentations at this year’s Defcon detailed fairly comprehensive methods of compromising some models.
Apple To Acquire Embark

Comments Off on Apple To Acquire Embark
Apple is reportedly purchasing mapping app developer Embark, in a move that could lend more real-time navigation features for public transit to Apple’s own Maps app.
The acquisition, which was first reported by tech journalist Jessica Lessin, follows other recent mapping purchases for Apple: HopStop, another maker of apps for public transit directions; and Locationary, which provides data about local businesses; and WifiSLAM, an indoor location and mapping company.
Apple did not directly confirm its acquisition of Embark, but in an emailed statement said, “Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans.”
Apple declined to comment further on the deal.
Apple has faced some serious challenges over the past year in providing a consistently solid mapping product with its Maps app. Last September Apple CEO Tim Cook was forced to publicly apologize for a series of issues plaguing the company’s Maps app in Apple’s iOS 6 operating system.
Embark is a company based in the San Francisco Bay Area that makes a mobile mapping app designed to help people navigate mass transit systems. The company’s app provides “tailored trips” specific to the user’s region, along with notifications for late-running trains and other advisories and closures.
Embark’s technology, if it does find its way into a future Apple product, could enhance Apple’s mapping products and make the company a stronger competitor to rivals like Google. Google’s Maps app already offers real-time public transit navigation features, as do some smaller players like iTransitBuddy.
Embark’s app is available for free on the iPhone for 10 transit systems including Boston’s MBTA, Chicago’s L, the New York City Subway and San Francisco’s Bart and Caltrain systems, with more on the way, according to Embark’s website.
It is not clear whether Embark’s app will be shut down as part of the acquisition. The app was still available in Apple’s App Store at the time of this article’s posting.
Embark’s team could not be immediately reached to comment on the deal.
