drag2share: More Snapchat Security Concerns

MORE SNAPCHAT SECURITY CONCERNS: A security researcher found that he could run a program that sends so many messages to a Snapchat user that it crashes the recipient's iPhone (it doesn't appear that he tested other mobile devices). The security hack is what's known as a denial of service (or, DoS). DoS attacks attempt to overload a server with thousands of requests in seconds, which can cause the entire service to crash. Twitter used to be a target of this type of hack in its early days. Snapchat needs to fix this vulnerability, and prevent future DoS attacks if it wants to mature into a reliable service for users.

Article: Record-breaking DDoS attack struck on Monday, according to reports

Somebody out there was getting hit hard by a distributed denial-of-service (DDoS) attack on Monday, according to multiple reports. And it looks like this one was even harsher than last year’s Spamhaus incident, at the time the biggest known DDoS attack in the history of the internet. According to...

With ARM's Cortex-A17 processor, midrange smartphones and tablets will be much faster

Source: http://www.engadget.com/2014/02/11/arm-cortex-a17/

We already have a hard time finding fault with processing power in the midrange smartphones and tablets currently on the market, but that doesn't mean they couldn't be even snappier. That's the goal of ARM, which has announced the latest Cortex processors, known as Cortex-A17, to address not only mobile devices in the midrange market, but Smart TVs and Over-the-Top devices as well. The 28nm A17 comes with big.LITTLE (the architecture used in Samsung's latest octa-core Exynos chips) support, and promises a 60 percent boost in performance over Cortex-A9. It's also paired with a Mali-T720 GPU, which offers OpenGL ES 3.0 support and plenty of optimizations for low-end Android devices. While ARM doesn't specify an actual timeframe for release, it says that we should expect a huge push for the A17 in 2015; in a separate release, MediaTek also tells us that its newest octa-core processor comes with Cortex-A17 tech inside and will be available in the second half of this year.

MediaTek's new octa-core processor to compete with Qualcomm over the premium LTE smartphone market

Source: http://www.engadget.com/2014/02/11/mediatek-octa-core/

MediaTek, a chipset manufacturer based out of Taiwan, has been making some huge moves lately. Just over two months ago, it came out with the "world's first true octa-core" processor, which consisted of eight Cortex-A7 cores capable of operating simultaneously. Now that ARM has announced Cortex-A17 technology, however, MediaTek is ready to start sampling a new octa-core chip that consists of four 2.2-2.5GHz A17 cores and four 1.7GHz A7s, and comes with a Rogue PowerVR Series6 GPU to take care of any graphical needs you might have.

As an aside, the A17 cores come with a 60 percent improvement in performance over the current-gen A9s, and are primarily designed to make midrange smartphones and tablets even faster. That said, MediaTek tells us that its new chips, known as the MT6595, are actually meant to be featured in premium devices and will square off directly against Qualcomm's Snapdragon 800 and 805. And it's certainly got a few noteworthy features: first, the chip will use ARM's big.LITTLE architecture and Heterogeneous Multi-Processing, which means you can use all eight cores for the most intense tasks, or you can use just one or two at a time for incredibly basic activities. The company claims that this chip will be faster and more power efficient than the octa-core Exynos options, which feature four A15 cores and four A7s at lower frequencies.

Additionally, the MT6595 claims to be the first octa-core LTE system-on-chip with an H.265 Ultra HD Codec built-in to the platform, which offers 4K2K video recording and playback capabilities. In much the same way that most manufacturers don't enable all of a chip's features, however, it'll be up to each individual company to add it in. The chips will begin sampling to phone makers and carriers in the first half of this year, and it's expected to arrive in products during the second half. And while it should find its way into smartphones and tablets around the world, MediaTek wants the MT6595 to enjoy a huge presence in the US.
