Delicious Digg StumbleUpon Reddit Subscribe to RSS Feed

We all have a cameraman hidden somewhere inside us, who wants to capture the world from his own perspective. Some of us want to make a cool documentary about life on campus, others want to bring the local life under the spotlight, but with a good eye for detail, you also need an exceptional camera that will make your dream movie leave an impression on anybody who watches it. From the team behind Camera360 for iOS comes Movie360, an app that lets you record videos with thirteen amazing real-time effects, and up to a length of two hours per clip.

The app has a good-looking built-in 3D browser that allows you to play and delete your recorded videos or copy them to the Camera Roll. The app can record videos in three levels of quality.The video quality is set to Low by default. To switch to High or Medium quality, tap the settings button in the top-right corner of the app. The settings screen also lets you set the app to auto-save clips to Camera Roll.
At High quality, the app records videos at a resolution of 480×360, which is much lower than the highest resolution at which certain iDevices can capture videos, but the results of the applied effects are, nevertheless, impressive.
The app is available for free on the iTunes App Store and can be downloaded from the link provided below

ICS-CERT Warns of Hardcoded Backdoors in Industrial Control Systems

Delicious Digg StumbleUpon Reddit Subscribe to RSS Feed

Independent security researcher Rubén Santamarta has published details of hardcoded backdoors in the Schneider Electric NOE771 Quantum Ethernet Module. Subsequently the US Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) has published an alert warning of the multiple vulnerabilities in the module.
The backdoors are as follows:
  • Telnet port – May allow remote attackers the ability to view the operation of the module’s firmware, cause a denial of service, modify the memory of the module, and execute arbitrary code.
  • Windriver Debug port – Used for development; may allow remote attackers to view the operation of the module’s firmware, cause a denial of service, modify the memory of the module, and execute arbitrary code.
  • FTP service – May allow an attacker to modify the module website, download and run custom firmware, and modify the http passwords.
Rubén’s research shows are creditionals are hardcoded in Java Jar files stored on the device. For example Rubén shows the ftp username (‘sysdiag’) and password. The result is that:
  • Modicon PLCs can be compromise via the NOE Ethernet modules through ftp, telnet, modbus, WDB, snmp, web etc.
  • An attacker could load their own trojanized firmware.
  • There are non-documented hidden accounts that can be used to compromise a PLC.
The affected products are:

AMD A8-3850 Review: Llano Rocks Entry-Level Desktops

Delicious Digg StumbleUpon Reddit Subscribe to RSS Feed

Earlier this month we previewed AMD's Llano architecture in a notebook environment. Now we have the desktop version with a 100 W TDP. How much additional performance can the company procure with a loftier thermal ceiling and higher clocks?
Editor's Note: As we've done so many times before, we're partnering up with CyberPower to give away one of the first Llano-based desktop machines, which the builder calls its Gamer Ultra, to one of our readers. Flip through our review and, on the last page, enter to win a brand new PC, compliments of CyberPower!
A8-3850 Makes Its Desktop Debut
Don Woligroski did an absolutely killer job on our first look at AMD’s Llano architecture. If you haven’t yet read that story and you want to know more about the plumbing inside the company’s first mainstream APU, you really owe it to yourself to check out The AMD A8-3500M APU Review: Llano Is Unleashed before diving into this piece.
Because Don covered the underlying architecture so well, I’m going to use our first experiences with AMD’s Llano-based desktop platform, code-named Lynx, to dive deeper into the stuff I know you guys love: benchmark results and analysis. What kind of performance can you expect out of Dual Graphics? How does Sandy Bridge with discrete graphics compare? What effect does memory performance have on gaming frame rates? How does integrated USB 3.0 support measure up to some of the add-on controllers we’ve seen? I’ll answer all of that.
But first let’s go over the basics of AMD’s first desktop-class Llano-based APUs.
Zoom
Llano: The Recession-Friendly APU
Oh, Audi would be so proud (or maybe not, given the entry-level pedigree of these processors). AMD is using the same A8 and A6 designators to distinguish between the perceived performance levels of its four launch SKUs.
There are two A8s and two A6s. The Llano-based flagship is A8-3850, a 100 W part with Radeon HD 6550D graphics, four execution cores with 1 MB L2 cache each, and a 2.9 GHz clock rate. That part does not offer Turbo Core support—the only way to get it running faster than 2.9 GHz is through overclocking. AMD says to expect pricing around $135.

The A6-3650 is also rated at 100 W, even though it’s armed with Radeon HD 6530D graphics and a more conservative 2.6 GHz clock rate (again, Turbo Core isn’t available). The -3650 boasts four cores as well, includes the same 4 MB of L2 cache, and support DDR3-1866 data rates, just like the other three models. That one is expected to run $115.

A6-3600HD 6530D65 W42.1 GHz2.4 GHz4 MB320443 MHzYes

Interestingly, dipping down to the 65 W level doesn’t seem to sacrifice much in the way of functionality. AMD’s A8-3800 includes the capable Radeon HD 6550D engine, quad-core Stars architecture, and 4 MB L2 repository. However, Turbo Core helps compensate for a fairly severe drop to 2.4 GHz, kicking frequency up to 2.7 GHz in situations where thermal headroom allows for it. Unfortunately, AMD didn’t send over any Turbo Core-equipped processors for testing, so it’s impossible to gauge how much time this four-core part spends at its elevated setting.
Finally, the A6-3600 is also a 65 W component. It scales way back, though, giving up not only processor clock rate—its four cores running at 2.1 GHz by default and up to 2.4 GHz with Turbo Core—but also graphics performance via the less-complex Radeon HD 6530D engine. Is still includes 4 MB of L2 cache though, complementing each core with 1 MB.
What's the difference, exactly, between the Radeon HD 6550D and Radeon HD 6530D GPU engines? One SIMD engine, for the most part.
Graphics Processor ClassificationRadeon HD 6550D (A8-Series APUs)Radeon HD 6530D (A6-Series APUs)

Render Back-Ends22
Z/Stencil ROPs3232
Color ROPs88
GPU Clock Rate600 MHz443 MHz
Peak Compute Power480 GFLOPS284 GFLOPS

When you look at a block diagram of the Llano's GPU component, it's easy to see how AMD differentiates these two lineups. Each SIMD hosts 80 ALUs and is associated with four texture units. Turning one SIMD off yields the 320 shaders and 16 texture units offered by Radeon HD 6530D.
Zoom
A Small Launch Gets Smaller
With four SKUs in the initial Llano-based desktop portfolio, a zero-hour revelation that the 65 W A8-3800 and A6-3600 won't be available until an undisclosed date narrows the family down to two models: A8-3850 and A6-3650, both 100 W parts. As a result, it won't be possible to test Turbo Core functionality on Llano until AMD addresses the availability of its lower-power offerings.

Intel Core i7-3960X Review: Sandy Bridge-E And X79 Express

Delicious Digg StumbleUpon Reddit Subscribe to RSS Feed

Intel's Sandy Bridge design impressed us nearly a year ago, but it was intended for mainstream customers. The company took its time readying the enthusiast version, Sandy Bridge-E. Now, the LGA 2011-based platform and its accompanying CPUs are ready.
According to Mick Jagger, it’s lonely at the top. Intel might agree. After all, for the past five years, the company has put an increasingly large gap between its fastest desktop processors and AMD’s own best efforts. Enthusiasts tend to lament the fact that a lack of intense competition means they pay more for high-end hardware. But, if you’ve been around long enough, you know that Intel’s Extreme Edition CPUs were always thousand-dollar affairs and, once upon a time, AMD’s vaunted FX-series chips used to be worth their $700+ asking prices.
The fact that the $1000 price point persists today, eight years later, means Intel recognizes the extremely limited market for these flagship desktop processors and isn’t about to push one of its crown jewels even further out of reach. 
It comes as little surprise, then, to see yet another Extreme Edition processor hovering around $1000. But this behemoth is very different than what came before.
The prior generation of flagship parts based on Gulftown came armed with six physical cores and up to 12 MB of shared L3 cache. They boasted LGA 1366 compatibility, extending the useful lives of pricey X58 Express motherboards, helping soften the blow of $500+ processor upgrades. No such luck this time; you’re facing a pricier investment.
Sandy Bridge-E, Gulftown’s successor, employs an LGA 2011 interface, requiring new motherboards based on Intel’s X79 Express Platform Controller Hub. It also comes armed with an integrated quad-channel memory controller, necessitating four-module memory kits. Oh, and then there’s the fact that Intel isn’t planning to bundle its new chips with coolers, requiring a separate purchase there, too.

Meet Sandy Bridge-E

Intel is announcing three Sandy Bridge-E-based models today, but only two will be available through the end of 2011: Core i7-3960X and Core i7-3930K. The third, Core i7-3820, is slated for a Q1 2012 introduction.
Gulftown is big; Sandy Bridge-E is much biggerGulftown is big; Sandy Bridge-E is much bigger
2011 pins require a lot of space2011 pins require a lot of space
All three employ the same die, which is composed of 2.27 billion transistors and measures 434 square millimeters (making it a very big chip). In comparison, quad-core Sandy Bridge parts are made up of 995 million transistors and measure 216 square millimeters, while six-core Gulftown CPUs incorporate more than 1.1 billion transistors in a 248 square millimeter die.
Of course, Sandy Bridge-E was never intended to be a desktop processor exclusively. Rather, it’s going to emerge in the first part of next year as Xeon E5 for single- and dual-socket servers/workstations. In that context, the CPU’s size and complexity makes more sense. After all, Westmere-EX (at the heart of Intel’s more enterprise-oriented Xeon E7 family) is a 2.6 billion-transistor die occupying 513 square millimeters of space.
Core i7-3960X, with two cores and 5 MB L3 cache disabledCore i7-3960X, with two cores and 5 MB L3 cache disabled
When Sandy Bridge-E surfaces as Xeon, it’ll offer up to eight processing cores and 20 MB of shared L3 cache. As a desktop CPU, however, it’s limited to as many as six cores and up to 15 MB of shared L3. Intel achieves this by disabling two cores and four of the die’s 16 slices of shared L3 cache.
Of course, that configuration only applies to Core i7-3960X. Core i7-3930K, which also features six cores, dips down to 12 MB of cache, revealing Intel’s ability to very granularly disable pieces of the shared L3 to suit its needs. The upcoming Core i7-3820 will employ four cores and 10 MB of shared L3 cache—essentially half of a Sandy Bridge-E die. Each core includes 32 KB of L1 instruction and L1 data cache, plus a dedicated 256 KB L2 cache.
Sandy Bridge-E Family

Base ClockMax. TurboCores / ThreadsL3 CacheTDPMemoryPrice

Core i7-38203.6 GHz3.9 GHz4 / 810 MB130 W4-Channel DDR3-1600TBD

The clocks on all three SKUs range up and down as well. The -3960X starts at 3.3 GHz and, through the same second-gen Turbo Boost technology introduced with Sandy Bridge, speeds up to 3.9 GHz. The -3930K starts at 3.2 GHz and hits a peak of 3.8 GHz in lightly-threaded workloads. Finally, the -3820 will start at 3.6 GHz and reach frequencies of up to 3.9 GHz with Turbo Boost.
Of course, the X- and K-series chips are also multiplier-unlocked, making those stock clocks pretty much meaningless for most enthusiasts planning to tweak their systems. Intel calls the -3820 “partially unlocked.” In all actuality, it gets six 100 MHz bins above its maximum Turbo Boost setting of 3.9 GHz, translating to a ceiling of 45x.


Intel is using the same cores found in its Sandy Bridge-based CPUs. Turning off Turbo Boost, setting similar base clocks, and running a couple of single-threaded apps demonstrates the efficient execution Sandy Bridge brings to the table compared to Thuban or Zambezi.


Switching Turbo Boost back on and running Core i7-3960X in parallelized and single-threaded titles gives us a better impression of what that technology does for performance.
In an application like iTunes, which is only able to utilize one core, Turbo Boost improves performance by 12.8%. In 7-Zip (well-optimized to use available cores), it increases performance by 10.8%. The second number is surprisingly high because Turbo pushes an additional three 100 MHz bins when five or six cores are active and none of the technology’s triggers are tripped. As a result, it's tackling our compression workload at 3.6 GHz instead of 3.3

Use 'Run As' To Execute Programs As Administrator

Delicious Digg StumbleUpon Reddit Subscribe to RSS Feed

Security administrators and experts often preach that users should use the least-privileged user account they can, without adversely impacting their productivity, for day-to-day tasks and activities. All-powerful accounts such as the Administrator account in Microsoft Windows should be reserved for only when they are needed.
Part of the reason is so that you don't accidentally access or modify files or system configurations that you shouldn't be. The other part of the reason is that viruses, Trojans and other malware often execute using the access rights and privileges of the account being used. If you are logged in as Administrator, a virus or other malware infection will be able to execute virtually anything with carte blanche on the computer. Logging in as a normal, more restricted user can help secure and protect your system.
However, it can be frustrating to have to log out and log back in as Administrator to install a program or modify a system configuration, and then log out again and log back in as a regular user. Thankfully, Microsoft added a feature called 'Run As' which allows you to run programs using a different username and password than the one currently logged in.

How To Use 'Run As'


If you find that you need to install programs or make changes to the system that require Administrator access, or even if you need to access files or folders of another user but don't want to log out and log back in as that user, you can use the 'Run As' command by following these instructions:
  1. Right-click on the file or program you wish to run. (You can right-click on executable file names in a Windows Explorer window, or you can right-click on programs listed in the Start menu.)
  2. Click the radio button next to "The following user:"
  3. Enter the username of the account you wish to log in as. (You can also click arrow on the drop-down box for a list of available user accounts.)
  4. Enter the password for the account being used.
You do not need to do anything to "turn off" that access. Only the program you execute using 'Run As' will run using the account you choose. Once you exit that program, everything is still just as it was when you started.

Change Processor Name Permanently

A while ago on Technology Inspired, I published an article on changing your processor name. But recently, Technology Inspired reader Anil Kumar pointed out that the trick only changed the name temporarily.

After a user restarts his computer, the name reverted back to original which is obvious as each time Windows boots, it checks the connected hardware and updates the registry value automatically. So, changing the processor name using the earlier article did not had permanent effect on the processor name.
