Android botnet turns infected handsets into SMS spam generators

A new Trojan called SpamSolider that infects Android devices is to blame for an increasing number of spam text messages in the US. The malicious software is bundled alongside free versions of popular mobile games like Angry Birds Space and Need for Speed: Most Wanted, according to a recent report from The Register.
Once SpamSolider has infected a handset, it goes about sending out a slew of bogus text messages offering recipients a web link to a free game. Often times, a free game actually accompanies the spam but it’s just used as a distraction so users won’t get suspicious.
In the meantime, SpamSolider is busy sending out thousands of unsolicited SMS messages. The Trojan downloads a list of phone numbers from a command and control server, according to Andrew Conway from Cloudmark. The researcher said his company has seen a peak rate thus far of more than half a million texts per day courtesy of SpamSolider.
Researchers believe the person(s) behind the Tronajn first released it into the wild back in late October. It was originally marketed as an anti-spam app before the author changed course and decided to lure unsuspecting victims in with the offer of a free game instead.
It wasn’t until November 28 that the spammer began to monetize the attack with free gift card offers. As Conway points out, there are ultimately no free gift cards for the victim. Instead, spammers get to collect your personal data to use for affiliate programs to line their pockets with cash.

Facebook is experimenting with paid messages sent to strangers

On December 21, 2012, 8:30 AM EST
Facebook is testing a new feature that will allow some users to send messages to people they aren’t friends with. It may not sound like a big deal initially until you realize that the social network will be charging for the convenience – or inconvenience, depending on how you see it.
It’s the latest in Facebook’s continued campaign to generate additional revenue streams which, if nothing else, will make investors happy. As recently noted on the official Facebook blog, a select number of users now have the option to pay to have a message routed to a non-friend’s inbox.
Up to this point, Facebook has used social signals such as friend connections and algorithms to identify spam and determine relevance. Messages determined to be less relevant would usually end up in the “other” folder and thus, often overlooked.
Users interested in sending an “unsolicited” message will be charged $1 per person it’s sent to. It could be a worthy investment if you’re trying to get in touch with someone you might not otherwise have access too but at the same time, those $1 fees could add up quickly if you plan to send out a lot of messages.
As CNET points out, Facebook has a wealth of user data but very few credit cards on file. New features likepromoted photos / posts, gifts and now this will certainly help the social network collect more credit card information. The only question that remains is, how badly do you want to reach out and speak to someone?

Samsung announces ultra fast 16GB MicroSD memory card

South Korean technology giant Samsung Electronics looks set to bolster its position as the world’s leader in advanced memory technology with the launch of a new ultra-fast MicroSD format memory card product targeted at tablets and 4G LTE smartphones.
The new MicroSD card format is built from 20-namometer class 64Gb toggle DDR 2.0 NAND flash memory, which will initially be offered in a 16GB version using their new UHS-1 (ultra high speed) interface. The new cards are said to be capable of sequential data read speeds as fast as 80MB/sec -- almost four times that of the current industry leader’s maximum of 21MB/sec.

This marks the first time the UHS-1 technology has been implemented into Micro SD memory cards, although the technology has already featured on full size SD cards used in digital SLR cameras and video recorders.
"[The UHS-1 interface] allows consumers to enjoy high-quality images and video playback directly from the memory cards," said Wanhoon Hong, Samsung’s executive vice president for memory sales and marketing. "Our UHS-1 card demonstrates how Samsung plans to continually expand its line-up of memory cards in accommodating the market need for higher densities and greater performance."
They appear to be ideal when paired as a storage medium for 4G LTE smartphones where the increased transfer performance will match the increased bandwidth LTE devices have, as well as providing high speed data storage for tablets capable of using the MicroSD memory card design.
Samsung began production of the new 16GB UHS-1 Micro SD memory cards late last month. As production increases the firm will expand their offerings with "higher density solutions that reinforce its position as the leading market innovator for NAND flash." So it’s possible we could see 32GB versions arriving later in the year.
There is currently no word on pricing or availability, but given the announcement it’s likely to start appearing on store shelves within the next couple of months.

IBM to build low-power, exascale computer for largest-ever radio telescope

ibm, research, science, ska, astron, exascale, supercomputers, petascale, exabytes, exaflops, petaflops, petabytes, parallel computing, telescope, astronomy, low power
For the next five years, IBM will be working with the Netherland's National Institute of Radio Astronomy (ASTRON) in hopes of developing a low-powered, exascale supercomputer. According to IBM, such a computer would be millions of times faster than today's high-end desktop PCs and possibly thousands of times faster than even the most recent super computers. The computer will be used to analyze data collected by SKA (square-kilometer array), a cutting-edge radio telescope which will become the largest and most sensitive of its kind ever built. ASTRON plans to have the telescope ready by 2024.
Exascale refers to a computing device that is so incredibly fast, the number of floating-point operations per second it can perform is measured not in gigaflops or even petaflops, but exaflops. Today, even the highest-end desktop CPUs clock-in around 20 gigaflops. Even when you consider the current masters of parallel computing, GPUs, FLOPS of the peta-kind are still unheard of outside the realm of supercomputing.
This low-powered supercomputing cluster will be charged with the task of collecting, storing and analyzing exabytes worth of astronomical data on a daily basis. To put this into perspective, for each day it operates, the amount of data which will be collected is expected to exceed the sum of raw data transferred through the entire Internet, globally. In fact, under ideal conditions, it may be more than twice as much.
To maintain a combination of high performance and low power, IBM will be investigating a number of its own experimental technologies, including 3D stacked circuits and novel optical transfer technologies.
A few interesting facts:
  • SKA will need to store up to 1,500 petabytes of data per year.
  • The computer will need to manipulate  bewteen 1 to 3 exabytes of data per day.
  • 64-bit architecture currently has an address limit of 18 exabytes.
  • SKA will survey over 3000km of sky at a time, nearly the width of the continental U.S.

Apple overtakes RIM in smartphone sales on their home turf

apple, iphone, rim, canada, blackberry 10
Apple has knocked off Research in Motion as the top smartphone provider in Canada for the first time. Canadians have remained loyal to RIM through some hard times over the past few years but the troubled company based in Waterloo, Ontario wasn’t able to fend off Cupertino in 2011.
RIM shipped 2.08 million Blackberry devices in Canada last year, compared with 2.85 million iPhones in the same time frame. This is in stark contrast to 2010 where RIM sold over half a million more handsets than Apple. In 2008, Blackberry phones outsold the iPhone by nearly a five to one ratio. Bloomberg notes that sales in Canada represent about seven percent of the company’s total revenue.
As one of the largest global brands to emerge from Canada, RIM has enjoyed local support which makes it even more troubling that an outsider has overtaken them on their home turf. The downturn can be credited to any number of factors, but Alfred DuPuy from research firm Interbrand hit the nail on the head when he essentially said RIM didn’t invest enough in promoting their devices once the iPhone shipped.
It will be up to RIM’s new CEO Thorsten Heins to try and steer the company back in the right direction. RIM plans to give prototype Blackberry 10 devices to developers in May so they can get started on producing apps for the new operating system set for release this fall.

Adobe Photoshop CS6 beta now available as free download

March 22, 2012, 11:30 AM EST
Adobe has released a beta version of Photoshop CS6 that is free to download and try. The latest installment of the popular photo editing software for PC and Mac is said to have 60 percent more features than CS5 including around 65 user-requested features.
Last month Adobe demonstrated a couple of impressive new features known as content-aware move and the extend tool, both of which are included in CS6. Content-aware allows the user to select an object and move it to a different location in the photo. The software’s algorithm will do all of the work, effectively moving the object and filling in the empty space with a believable background based on the surround areas.
An extension of the content-aware mode called extend (no pun intended) allows you to lengthen an object in the scene by grabbing and stretching it. Adobe has also added a Camera RAW sub-application that provides the user with better control over their RAW images. CS6 can even make automatic adjustment based solely on a user’s lens profile.
Adobe has also included a set of video editing tools for the traditional photo editor. PC Mag notes that users can split and join clips, add transitions between different segments and even apply photo adjustments to the video like brightness, contrast and tint.
"Photoshop CS6 will be a milestone release that pushes the boundaries of imaging innovation with incredible speed and performance," said Winston Hendrickson, vice president of products for Adobe Creative Media Solutions. "We couldn't wait to share this beta of Photoshop CS6 with our customers and are looking forward to hearing from them and seeing the ways they are incorporating the beta into their daily creative workflows."
In addition to the new features, CS6 has been redesigned with a darker interface, although users can selected a lighter gray background in the options.
The beta is available now for anyone on a PC or Mac to download and try. Adobe will be releasing the full version in the second half of 2012 at $699 for the standard version and $999 for the Extended package. Adobe now offers a subscription model that starts at $35 per month with a one-year commitment or $49 on a month-to-month basis.

Intel Core i7-3820 Processor Review

Intel Core i7-3820 Processor Review
Late last year when we reviewed the new Sandy Bridge-E processors, we mentioned a more affordable version called the Core i7-3820 was coming. Although information about the chip had been revealed, the processor has yet to hit shelves and is now expected to arrive later in February. Fortunately, sample units are being passed around ahead of general availability, so we don't have to wait to see how it stacks up.
The i7-3820 is particularly intriguing because of its sub-$300 retail price -- far less than other chips in the series. For instance, the Core i7-3960X has an MSRP of $999 and sells for more like $1,049, while the i7-3930Khas an MSRP of $583 and is fetching $599 at e-tail. Both are six-core CPUs operating over 3GHz with massive 15MB and 12MB L3 caches.
At roughly half the price of the 3930K, we expected Intel to butcher the i7-3820, and while that's partially true, the 3820 remains an impressive specimen with four cores operating at 3.6GHz, a 10MB L3 cache and HyperThreading support. Compared to the similarly priced i7-2600K, the 3820 offers additional L3 cache, support for PCI Express 3.0, quad-channel memory and a platform that will take as much as 32GB of system memory.
Although LGA2011 features some new tricks absent on LGA1155, we're disappointed in the chipset support. The X79 is rather lackluster and has nothing new to offer over Z68. Still, the raw power of SB-E is its strongest selling point and we're keen to see how the affordable variant performs and how it compares to the very popularCore i7-2600K.
Some have anticipated the i7-3820 will be in somewhat of an awkward position in terms of pricing. Although processors command a similar rate, the platform behind the i7-3820 is considerably pricier than the 2600K's. Whereas Z68 motherboards can be had for less than $100, basic X79 boards start at $200, and most cost around $230.
Additionally, the i7-3820 supports quad-channel memory meaning users will be compelled to purchase four modules rather than just two. Core i7-3820 owners might pay up to $200 more for the same performance as folks who opt for the i7-2600K, which doesn't make sense unless you need the extra PCI Express bandwidth or the larger memory capacity -- or so it appears on paper. Let's see what the tests have to say.

Samsung Galaxy Note Review

Samsung Galaxy Note Review
Samsung's new Galaxy Note is a unique device in the smartphone market. Straddling the line between a smartphone and a tablet, the Note features a massive 5.3-inch display, which is considerably larger than the screen on any other smartphone available today (just see the image below sitting alongside an iPhone). Because of this, the Note is rather unwieldy in the hand, and nearly impossible to use one handed.
Trying to make the most of the smartphone's larger footprint, Samsung has attempted to add functionality to the Note with its "don't-call-it-a-stylus" S Pen input device. But once again the Note's dominant feature is its 5.3-inch, Super AMOLED display that packs a dense 1280 x 800 pixel resolution. The form factor alone will place many potential buyers at odds, while others might appreciate the hybrid nature of the device. Read on to learn our findings.
Samsung Galaxy Note
Hardware
The Samsung Galaxy Note borrows heavily from the designs Samsung has used for its Galaxy S II line of smartphones. In fact, one would not be faulted for thinking that the Galaxy Note was just a Galaxy S II on steroids. The big display looks fantastic, with great, punchy colors, tremendous viewing angles, and good outdoor visibility. The pixel layout is the much-derided PenTile format, but since there are so many pixels packed onto the screen, you have to really hunt to see any PenTile patterns in images. It really is a great display.
Because of the massive screen, the Note has equally large dimensions - and therein lie the difficulties I had with using it as a phone. The Note measures 147mm (5.78in) tall and 83mm (3.27in) across, which means that it feels absolutely massive when held in the hand. Even compared to the already large Samsung Galaxy S II Skyrocket with its 4.5-inch display, the Note is a enormous beast (and it makes the 3.5-inch iPhone 4S look positively diminutive). I am unable to reach the corners of the screen with my thumb without having to significantly move the Note around in my hand and stretch to my hand's fullest extent, which gives me concern that the Note will slip out of my hand and fall to the ground.
Thus, using the Galaxy Note is a two-handed affair, and there really isn't a way to get around it -- unless you are a pro basketball player, I suppose. However, despite its large dimensions, the Note remains very thin at only 9.7mm (0.38in) thick. As with many thin Samsung smartphones, the thin profile of the Note certainly makes it feel even larger than it actually is.
The rear cover of the Note is made of the familiar, thin plastic material that Samsung has used on many of its prior models, but the Note's back features a classier texture than the others that makes it feel as if it is of higher quality. The textured back helps in handling the device, though I am not sure it will prevent users from eventually dropping it.
Samsung Galaxy Note
Tucked in the lower right corner of the Note's frame is the S Pen input device. The S Pen uses Wacom technology and works with the digitizer in the Note's display to allow users to draw and activate things on the screen with the pen-like tip. The tip has 256 levels of pressure sensitivity, so apps that support the S Pen's capabilities can allow the user to draw thick or thin lines depending on how much pressure they put on the screen.
The S Pen also has a function button on the side of it to perform various tasks like screen capture. Unlike the Scrybe pen for HTC's Flyer tablet, the S Pen does not require a battery. The housing that the S Pen fits into is snug, and the pen won't fall out unintentionally. Still, the S Pen is very thin and small, and many users will likely lose it at some point during their Galaxy Note ownership (AT&T and Samsung are offering replacement S Pens for $29 a pop).

HP TouchSmart 520 All-In-One Review

HP TouchSmart 520 All-In-One Review
“What’s the first thing you noticed when unboxing the system?” asked an HP representative during a briefing call regarding the TouchSmart 520 all-in-one PC I’d received for evaluation a week or so earlier. I told the rep that the system was extremely heavy which prompted a discussion regarding the weighted aluminum base, freestanding configuration and more.
Bill Gates unveiled the first HP TouchSmart at CES in 2007 and we’ve seen a number of updates throughout the years since. The latest rendition sports some serious hardware and a slightly revised design but had it not been for some corporate restructuring at HP, the unit likely would never have seen the light of day; but I digress.
HP supplied us with their TouchSmart model 520-1070 which they described as the star of their current all-in-one lineup that features a lighter, thinner design and an upgraded version of HP’s Magic Canvas software.
The 23-inch multi-touch AIO is powered by a 2nd generation Intel Core i7-2600S processor clocked at 2.8GHz, 8GB of DDR3 system memory, a 2TB Western Digital Caviar Green hard drive, Radeon HD 6450A graphics and Beats Audio. Additional perks include a built-in TV tuner and HDMI-in, essentially transforming the 520 into a venerable entertainment / gaming station.
Despite the heavy multi-touch focus, HP knows that most users won’t rely strictly on physical interaction with the interface. As such, they’ve also included a wireless keyboard, wireless mouse and media remote control for wire-free control. There’s also a power cord, power adapter with a relatively large ‘brick’, IR blaster cable and some various documentation that round out the bundle. Our price as configured here today is $1,399.
 
Aesthetically, HP has a great looking system on their hands. The dual-purpose aluminum base keeps the system firmly planted on the ground even when adjusting the angle of the display. It also serves as a keyboard shelf should you need more space on your desktop or when you go into touch-only mode.
Across the bottom of the display is a sound bar powered by Beats Audio. We’ve seen Beats branding on HP notebooks in the past but results are typically best achieved when listening with a pair of headphones. After all, one can only ask so much from a pair of laptop speakers. HP certainly has the room to add a decent set of speakers here; let’s hope they did just that.
The 23-inch backlit LED display features a native resolution of 1920 x 1080, 250 nits brightness, 1000:1 contrast ratio and a 5ms response time. The non-glossy black bezel houses an HD webcam with built-in microphone just above the screen.
On the left side of the computer we find storage and card reader LED indicators, a 6-in-1 card reader, two USB 3.0 ports, a microphone jack and a headphone jack. The rear I/O panel features four USB 2.0 ports, line-out and subwoofer-out jacks, a Gigabit Ethernet jack, power jack, IR blaster jack and the TV tuner coaxial jack.
HP has installed a slot-loading SuperMulti Blu-ray Burner on the right edge of the system just above four buttons used to manipulate on-screen display options. Finally there is an HDMI-in port, allowing you to use the display as a secondary screen for your notebook or even better, a primary display for your gaming console.
