Tagged: Internet, fact check
Definately falling into the "I'll beleive it when I see it" category is an extension developed by an MIT student for his Masters thesis which is intended to check the accuracy of information on the web. Specifically, with the help of Politifact it will be checking the accuracy of political statements. The big problem is going to be the quality of the facts database it checks against, as you can only be as good as the database so if it gets out of date or starts to lean one way or the other it might do more harm than good. On the other hand we can hope that this might make people a little more leery of getting their information from only one source and not doing even a bit of fact checking on their own. Take a look at the full story over at The Register.
Thanks Neiman Journalism Lab!
"A student at MIT’s Media Lab is developing a browser plug-in that can check the accuracy of information posted online, and may use it to monitor political speeches for untruths.
For his master’s thesis, Dan Schultz – who was recently named a 2011 Knight-Mozilla Fellow – came up with the idea for “truth goggles” while talking to a fact checker at Truthsquad, who was explaining that the principle problem with fact checking was getting people access to the skinny. Schultz then came up with the idea as a way to correct incorrect information, but more importantly to get people to think critically about what they are reading."

Tagged: Seagate, hdd, earnings
It seems very interesting that Seagate is so upbeat about their earnings with the flooding in Thailand causing huge supply shortages of HDD world wide. Last year at this time they were expecting 170 million units move, whereas this year is is 110-120 million units with demand outstripping supply. That number does reflect some supply issues but perhaps not as bad as the issues faced by Western Digital and other manufacturers with a large presence in Thailand. The profit being higher does show what happens when you have a product people want but cannot find; the price per unit quickly goes up and the business can still make a profit. We can only hope that as supply returns to the chain that the price drops at the same speed it has risen. We still do not have final word on Seagate's absorption of Samsung's HDD business, that will likely be in January.
CUPERTINO, Calif.--(BUSINESS WIRE)-- Seagate Technology plc (NASDAQ:STX) today updated its financial outlook for the December 2011 and March 2012 quarters.
The company continues to believe that, due to the industry impacts caused by the extensive flooding in Thailand, hard disk drive supply will be significantly constrained for several quarters. For the December 2011 quarter, the company believes the industry will ship between 110-120 million units.
The company believes the industry’s ability to manufacture and ship hard disks drives will gradually improve throughout calendar 2012. While this may alleviate some of the unit demand shortfall, it is expected that some companies will optimize unit shipments by manufacturing lower component count/lower capacity hard disk drives; thereby, only modestly offsetting the growing petabyte shortage. Because demand is estimated to significantly exceed supply during this time, pricing is expected to remain stable.
The company’s component and disk drive factories in Thailand have not been directly affected by the flood; however, the company’s ability to manufacture hard disk drives has been impacted due to external component supply constraints as first disclosed on October 12, 2011.
For the December 2011 quarter, the company now expects unit shipments of approximately 43 million units and revenue of approximately $2.8 billion. Gross margin as a percent of revenue is expected to be 150-300 basis points above the high-end of the company’s long-term, targeted gross margin range of 22-26%. Operating expenses (R&D and SG&A) are expected to be approximately $400 million. Expenses related to the acquisition of Samsung Electronics Co., Ltd’s (“Samsung”) hard disk drive business and any revenue or operating expenses of the acquired business following the closing date cannot be estimated at this time and are therefore excluded from this outlook. The company continues to expect to close the acquisition of Samsung’s hard disk drive business by the end of December 2011.
The company’s outlook for the March 2012 quarter assumes requisite regulatory approvals are received and the Samsung acquisition closes in December of 2011. The company also continues to work with its external suppliers to restore the component supply chain, and now expects that in the March quarter it will be capable of shipping a mix of products in terms of capacity per drive and expected market similar to pre-flood levels. Currently, for the March 2012 quarter, the company expects unit shipments to increase sequentially. Revenue is expected to be at least $3.75 billion and gross margin as a percent of revenue is expected to be at least 300 basis points above the aforementioned targeted range of 22-26%. The outlook for the March 2012 quarter excludes certain costs related to the integration of the acquired Samsung hard disk drive operations which cannot be estimated at this time.
The financial outlook provided today does not include the arbitration award previously disclosed on November 21, 2011.

Just Delivered is a new section of PC Perspective where we share some of the goodies that pass through our labs that may or may not see a review, but are pretty cool none the less.
Arriving just in time for my Thanksgiving break is a rather large but light box. Nestled inside lots of air bags are two boxes from popular computer case and peripheral maker Corsair. Specifically, the boxes include two pairs of Corsair's Vengeance series headsets, the Vengeance 1300 and 1500.
Both of the Corsair Vengeance headsets are gaming headsets with full closed ear or circumaural headphones and noise canceling unidirectional condenser microphones. The 1300 is an analog headset with two 3.5 mm jacks for the headphones and microphone while the 1500 is a USB powered 7.1 channel headset. The 1500 uses a single USB connection to deliver both headphone audio and the microphone audio and is stated to draw up to 250 mW from the USB port.
Both the Vengeance 1300 and 1500 have rotating ear cups that are also able to angle slightly up and down to fit comfortably in addition to the headband being able to extend or contract. The outside of the 1500 sports metal accents whereas the 1300 is plastic, making it a bit lighter, but they are both much lighter than they look to be. Further, both the 1300 and 1500 headsets have (non-removable) control pods on the 3 meter long cable to mute/un-mute the microphone and increase or decrease the volume level.
Initial impressions are positive, but it will certainly be interesting to see how they sound compared to other budget headsets, and whether or not they will live up to the same success that the HS1 and HS1A Corsair headsets held. Read on to see more photos of the Corsair gear!

Linux Mint Is On The Rise
Ubuntu has long been the popular choice when it comes to Linux distributions. The open source operating system even managed to be picked by large computer OEM Dell for the company’s netbooks and select desktop computers at one time. As far as free alternative operating systems go, Ubuntu was the top choice of many Linux users. Lately; however, the distro seems to be declining in popularity. According to ZDNet, Pingdom has gathered Linux market share data from the past few years and found that the once popular Ubuntu OS has given up a great deal of ground to competing distributions. In particular, Linux Mint has risen to the 11% usage level that Ubuntu held at its prime versus Ubuntu’s current 4% market usage in 2011.
Linux Mint 11's desktop.
Interestingly, Linux mint started at 0% adoption in 2005 versus Ubuntu’s 11% in that same year where it would grow to 4% in 2007 and grow slowly to 5% in 2010. From there, the adoption grows rapidly to it’s current 11% market usage as of November 23rd 2011 (based on DistroWatch ranking data).
Linux Mint 11 is a very respectable and speedy distribution and is comparatively very media friendly and easy to use out of the box for newcomers. These qualities likely have contributed to the operating system’s place on the Top 5 Linux Distribution list.
Wait- What Happened To Ubuntu?
Ubuntu gained fame due to its friendliness to newcomers, casual users, and enthusiasts/power users alike. Adrian Kingsley-Hughes over at ZDnet notes that the operating system’s popularity is wavering. Linux Fans have cited Ubuntu’s recent interface overhaul-dubbed Unity- as a possible source of the decline in popularity. Kingsley-Hughes believes; however, that in the latest iteration(s) Ubuntu has spread itself too thin by attempting to appeal to too many people at once.
The Ubuntu 11.10 installation. One of several slides on everything that is packed in tight in Ubuntu.
On that point I think he is correct. Ubuntu has been attempting to become the Windows equivalent of the Linux space. This goal in and of itself is a noble one; however, it also goes against the grain of the “ideal Linux OS” (meaning the OS that users want to use). Linux itself is (by comparison) a niche operating system, and within that general term spawns numerous Linux distributions that are even further niche and highly specialized products and user experiences.
I have to concur with Mr. Kingsley-Hughes on this one, even with my own personal lackluster (or “meh” in less technical terms ;) ) opinion of Ubuntu’s Unity it’s not bad or difficult enough to get rid of to cause such a drop in usage. The inherent purpose and goal of a Linux distro is to be a highly specialized and customizable user experience that is easily tailored to a specific users’ wants and needs. Ubuntu is falling out of favor with many Linux fans due to it trying too hard to appeal to everyone in a “jack of all trades, master of none” method instead of the perfect distribution for each individual aspect that makes Linux so appealing to users to begin with. Many design and under the hood changes have taken place in Ubuntu to accommodate the mainstream Linux goal(s) and in doing so a lot of users and configurations aren’t as easily obtained with Ubuntu anymore. There’s now more programs included by default and more programs running to maintain the something for everyone system, and that is not what many Linux fans want out of their distributions. They want a distro that only does what they want with as minimal of resources as possible while still being productive for example.
What are your thoughts? Is there a reason for Ubuntu’s decline or is the distro’s time in the spotlight simply over (for now at least)? Have you moved on from Ubuntu? You can read more about the Linux usage data here.

This year saw the 40th anniversary of (the availability of) the world’s first microprocessor- the Intel 4004 processor- and Intel is as strong as ever. On the supercomputing and HPC (High Performance Computing) front, Intel processors are powering the majority of the Top 500 supercomputers, and at this years supercomputing conference (SC11) the company talked about their current and future high performance silicon. Mainly, Intel talked about its new Intel Xeon E5 family of processors and the new Many Integrated Cores Knights Corner Larrabee successor.
The Intel Xeon E5 is available now.
The new Xeon chips are launching now and should be widely available within the first half of 2012. Several (lucky) supercomputing centers have already gotten their hands on the new chips and are now powering 10 systems on the Top 500 list where the 20,000 Xeon E5 CPUs are delivering a combined 3.4 Petaflops.
According to benchmarks, Intel is expecting a respectable 70% performance increase on HPC workloads versus the previous generation Xeon 5600 CPUs. Further Intel stated that the new E5 silicon is capable of as much as a 2x increase in raw FLOPS performance, according to Linpack benchmarks.
Intel is reporting that demand for the initial production run chips is “approximately 20 times greater than previous generation processors.” Rajeeb Hazra, the General Manager of Technical Computing of Intel’s Datacenenter and Connected Systems Group, stated that “customer acceptance of the Intel Xeon E5 processor has exceeded our expectations and is driving the fastest debut on the TOP 500 list of any processor in Intel’s history.” The company further reiterated several supercomputers that are set to go online son and will be powered by the new E5 CPUs including the 10 Petaflops Stampede computer at the Texas Advanced Computing Center and the 1 Petaflops Pleiades expansion for NASA.
While Intel processors are powering the majority of the world’s fastest supercomputers, graphics card hardware and GPGPU software has started to make its way into quite a few supercomputers as powerful companion processors that can greatly outperform a similar number of traditional CPUs (assuming the software can take advantage of the GPU hardware of course). In response to this, Intel has been working on it’s own MIC (Many Integrated Core) solution for a few years now. Starting with Larrabee, then Knights Ferry, and now Knights Corner, Intel has been working on silicon that using numerous small processing cores that can use the X86 instruction set to power highly parallel applications. Examples given by Intel as useful applications for their Many Integrated Core hardware includes weather modeling, tomography, and protein folding.
Knights Corner is the company’s latest iteration of MIC hardware, and is the first hardware that is commercially available. Knights Corner is capable of delivering more than 1 Teraflops of double precision floating point performance. Hazra stated that “having this performance now in a single chip based on Intel MIC architecture is a milestone that will once again be etched into HPC history” much like Intel’s first Teraflop supercomputer that utilized 9,680 Pentium Pro CPUs in 1997.
What’s interesting about Knights Corner lies in the ability of the hardware to run existing applications without porting to alternative programing languages like Nvidia’s CUDA or AMD’s Stream GPU languages. That is not to say that the hardware itself is not interesting, however. Knights Corner will be produced using Intel’s Tri-Gate transistors on a 22nm manufacturing process, and will feature “more than 50 cores.” Unlike current GPGPU solutions, the Knights Corner hardware is fully accessible and can be programmed as if the card is it’s own HPC node running a Linux based operating system.
More information on the Knights Corner architecture can be found here. I think it will be interesting to see how well Knights Corner will be adopted for high performance workloads versus graphics cards from Nvidia and AMD, especially now that the industry has already begun adapting GPGPU solutions using such programming technologies like CUDA, and graphics cards are becoming more general purpose (or at least less specialized) in hardware design. Is Intel too late for the (supercomputing market adoption) party, or just in time? What do you think?

Tagged: TSMC, 28nm, amd, krishna, wichita
The 28nm process is causing a lot of problems for tech companies especially AMD who have cancelled the follow ups to Llano and Ontario, Krishna and Wichita. Not only have they cancelled the chips but they have switched from GLOBALFOUNDRIES to TSMC to have the replacement chips designed and fabbed. This is most likely because of the low yields that have been coming out of GLOBALFOUNDRIES with Llano, AMD's most successful recent design. The low volumes hurt AMD's market share since many companies would not base a product line on a chip that might not be around in volume. As well a deal is expiring in January which had AMD only paying for good dies, instead of the more usual practice of paying for the entire wafer and dealing with the bad dies as they come
That move might not be as successful as AMD hopes when you look at this article from DigiTimes. As it turns out TSMC is concerned about their ability to meet the demand for 28nm chips from their customers. It is not just AMD that is turning to TSMC for 28nm, Altera, NVIDIA, Qualcomm and Xilinx are already customers and Broadcom, LSI Logic and STMicroelectronics may join that crowd. With so many customers utilizing the same process even small problems on TSMC's lines could lead to big drops in available chips. Let us hope the days of the 40nm problems at TSMC never come back.
"Taiwan Semiconductor Manufacturing Company (TSMC) continues to see orders heat up for advanced 28nm technology, despite a general slowdown in the semiconductor industry, according to industry sources. Order visibility has stretched to about six months, said the sources.
TSMC is expected to see 28nm processes account for more than 2% of company revenues in the fourth quarter of 2011. The proportion will expand further to over 10% in 2012, as more available capacity coupled with rising customer demand boost the output, the sources indicated."

When SteelSeries went about creating the Diablo 3 themed mouse, they decided not to just slap a paint job on an existing mouse, they actually added a bit to the design. A soft coating over the top of the mouse should help cushion your fingers so you can get a few extra thousand clicks out of them for your long Diablo III sessions. A 5700DPI sensor will see you through not only Diablo but any other game you might want and as the software supports macros you can string together a variety of commands for your avatar. Also included in Hardware Heavens review is the Diablo III branded Siberia V2 headset; are they just a common drop or are we looking at gold items? Read on to find out.
"Continuing their great working relationship with Blizzard SteelSeries are back with a new set of gaming peripherals based on the upcoming Diablo 3. We have the Diablo 3 Headset and Mouse on our test bench today and have been taking them through a few dungeon runs to find out how they perform."

Tagged: DIY, hack
Laptops have a harder life than desktops, not just because they get knocked around while you are on the move, but the plugs see a lot more action as you unplug your peripherals and power to put it in its case and plug them back in when you get to where you are going. As a result broken USB ports can be common but can be worked around, as can bent network pins but what about the power plug? Quite a few people have taken their laptop apart to clean the insides or to upgrade the RAM or other hardware but have you done any soldering inside the case or replaced plastic mounting points? Hack a Day will take you through a simple fix for a broken power plug on a Satellite which will bring your laptop back from the dead. This particular model is fixable because the power plug is not directly attached to the circuit board, a design which might be more brittle than direct attachment but does mean you can make these types of repairs.
This might take a little more ingenuity.
"It seems that there’s a whole range of Toshiba Satellite laptop computers that suffer from a power jack design that is prone to breaking. We see some good and some bad in this. The jack is not mounted to the circuit board, so if it gets jammed into the body like the one above it doesn’t hose the electronics. But what has happened here is the plastic brackets inside the case responsible for keeping the jack in place have failed. You won’t be able to plug in the power adapter unless you figure out a way to fix it."

Tagged: dx11, batman
We have been waiting for Batman: Arkham City for quite some time on the PC, and after weeks of delays, the game was finally released this week, to quite a bit of fanfare. NVIDIA has been touting the game as the poster child for several technology features like DX11, 3D Vision, PhysX, etc. It appears that the developers have had some issues though with the release - DX11 features are causing significant stuttering even with high end hardware.
Batman doesn't like it when his games are late...and broken.
I put together a quick video comparing the gameplay experience with and without DX11 enabled; you can see it below. The system specifications for our test bed for this video were:
- Intel Core i7-965
- Intel X58 motherboard
- 6GB DDR3-1600 memory
- GeForce GTX 580 1.5GB graphics card
- Driver version: 285.79
- Windows 7 SP1 x64
The DX11 settings that are causing the issues are tessellation, ambient occlusion and a new type of soft shadow rendering. When these features are enabled the game experiences noticeable, repeatable and quite annoying stutters both in the actual gameplay and during the integrated benchmark.
In our video below you can clearly the see the phenomenon in action.
On the official Batman: Arkham City forums, the publisher gave the following statement, confirming the broken DX11 implementation.
PC DirectX 11 Issues Please Read
We have received reports of performance issues from players of Batman: Arkham City on PC. After researching the matter, we found that running the game with DX 11 is causing the performance issues. We’re working on a title update to address this matter and expect to make it available in the near future.
In the meantime, a workaround for this issue is to run the game with DX 9 instead of DX 11. Instructions on how to turn off DX 11 are listed below.
We sincerely apologize for any inconvenience with your gameplay experience and thank you all for your patience as we work to resolve this issue.
While we love to see new technologies implemented in games that improve our gameplay experience, we HATE it when it delays games or causes issues like this when released. Here is hoping that the developer, publisher and driver teams from AMD and NVIDIA can fix this quickly.

Starting Skyrim for the first time was an interesting experience, obviously you once again start as a prisoner but perhaps one with some serious brain damage as reality seems to move in starts and jerks as if your eyes had a stuttering problem. Eventually the stuttering cleared up, providing a weekends worth of gaming but by Tuesday the stuttering had returned. It became clear that it was time to embark on every PC gamers favourite pastime; troubleshooting the game you just bought in the hopes of some day playing it.
Some troubleshooting revealed a serious case of consolitis, the game was not Large Address Aware and limited its self to a maximum serving of 2GB; the adoption of 64bit versions of Windows being very limited by the end of 2011. Even more damning was what happened when Intel's SpeedStep technology was enabled in the BIOS, the CPU would dip to about 60% of its maximum frequency when you played the game and the process would use under 10% of a core, maybe two if you were lucky. GPU usage was variable and was sometimes actually sitting at or above 90% usage, but for the most part varied widely.
A little research showed that SandyBridge owners and those with the previous generation of chips who overclocked above 4GHz were not having many problems, proving that the brute force method of overcoming consolitis could work. For those who haven't upgraded yet and are waiting for the new year to do so, they must either wait or find a more elegant solution. To the intarwebs!
INI file tweaks are always popular and Gamefront has a few, the most notable are bMouseAcceleration=0 and iPresentInterval=0 which disable mouse acceleration and V-Sync respectively. As well, over at Skyrim Nexus is a modified TESV.exe that makes the game LAA and more importantly does not need to replace the main executable in your Skyrim folder so that you won't need to worry about having a modified executable. As well adding the string +fullproc to the end of the path in your executable should help Skyrim utilize a bit more of your processor. In the end though, more tweaking is needed for some PC gamers to fully appreciate the latest Elder Scrolls game and more time needs to be spent researching general tweaks as well as Bethesda specific ones.
Now if only BF3 multiplayer would stop locking with a loud noise that sounds suspiciously like a raspberry.
