Our world is the host to numerous physical acts of aggression every day, and until a few years ago those acts have remained in the (relatively) easily comprehensible physical world. However, the millions of connected servers and clients that overlay the numerous nations around the world have rapidly become host to what is known as “cyber warfare,” which amounts to subversion and attacks against another people or nation through electronic means-- by attacking its people or its electronic and Internet-based infrastructure.
While physical acts of aggression are easier to examine (and gather evidence) and attribute to the responsible parties, attacks on the Internet are generally the exact opposite. Thanks to the anonymity of the Internet, it is much more difficult to determine the originator of the attack. Further, the ethical debate of whether physical actions in the form of military action is appropriate in response to online attacks comes into question.
It seems as though the Pentagon is seeking the answers to the issues of attack attribution and appropriate retaliation methods through the usage of an Internet simulator dubbed the National Cyber Range. According to Computer World, two designs for the simulator are being constructed by Lockheed Martin with a $30.8 million USD grant and Johns Hopkins University Applied Physics Laboratory with a $24.7 million USD grant provided by DARPA.
The National Cyber Range is to be designed to mimic human behavior in response to various DefCon and InfoCon (Informational Operations Condition) levels. It will allow the Pentagon and authorized parties to study the effectiveness of war plan execution as it simulates offensive and defensive actions on the scale of nation-backed levels of cyber warfare. Once the final National Cyber Range design has been chosen by DARPA from the two competing projects (by Johns Hopkins and Lockheed Martin), the government would be able to construct a toolkit that would allow them to easily transfer and conduct cyber warfare testing from any facility.

Yesterday saw the launch of Duke Nukem Forever. If you were a member of our forums for a long period of time you might actually have an odd case of deja vu. This is actually the second time that we have experienced the launch of Duke Nukem Forever. The first time was a sick joke one April fool’s day over nine years ago which is quite fitting for the lewd and crude franchise. Some argue that our current release is a sick joke, but that is a whole other story.
Duke Nukem: Forever and 3363 days.
Back in April 1st, 2002: Think Geek announced the availability of Duke Nukem Forever for Linux, Windows 3.1, WheatoniX, and Plan 9. The general buzz on the forum was about the marvel of being a PC gamer and how much of an impact Duke Nukem 3D had on our lives. So go on, nostalgia at the old fashioned giant PC gaming boxes and nostalgia at the forum thread long since forgotten.

During this morning's keynote at the AMD Fusion Developer Summit, Microsoft's Herb Sutter went on stage to discuss the problems and solutions involved around programming and developing for multi-processing systems and heterogeneous computing systems in particular. While the problems are definitely something we have discussed before at PC Perspective, the new solution that was showcased was significant.
C++ AMP (accelerated massive parallelism) was announced as a new extension to Visual Studio and the C++ programming language to help developers take advantage of the highly parallel and heterogeneous computing environments of today and the future. The new programming model uses C++ syntax and will be available in the next version of Visual Studio with "bits of it coming later this year." Sorry, no hard release date was given when probed.
Perhaps just as significant is the fact that Microsoft announced the C++ AMP standard would be an open specification and they are going to allow other compilers to integrated support for it. Unlike C# then, C++ AMP has a chance to be a new dominant standard in the programming world as the need for parallel computing expands. While OpenCL was the only option for developers that promised to allow easy utilization of ALL computing power in a computing device, C++ AMP gives users another option with the full weight of Microsoft behind it.
To demonstrate the capability of C++ AMP Microsoft showed a rigid body simulation program that ran on multiple computers and devices from a single executable file and was able to scale in performance from 3 GLOPS on the x86 cores of Llano to 650 GFLOPS on the combined APU power and to 830 GFLOPS with a pair of discrete Radeon HD 5800 GPUs. The same executable file was run on an AMD E-series APU powered tablet and ran at 16 GFLOPS with 16,000 particles. This is the promise of heterogeneous programming languages and is the gateway necessary for consumers and business to truly take advantage of the processors that AMD (and other companies) are building today.
If you want programs other than video transcoding apps to really push the promise of heterogeneous computing, then the announcement of C++ AMP is very, very big news.

Before the AMD Fusion Developer Summit started this week in Bellevue, WA the most controversial speaker on the agenda was Jem Davies, the VP of Technology at ARM. Why would AMD and ARM get together on a stage with dozens of media and hundreds of developers in attendance? There is no partnership between them in terms of hardware or software but would there be some kind of major announcement made about the two company's future together?
In that regard, the keynote was a bit of a letdown and if you thought there was going to be a merger between them or a new AMD APU being announced with an ARM processor in it, you left a bit disappointed. Instead we got a bit of background on ARM how the race of processing architectures has slowly dwindled to just x86 and ARM as well as a few jibes at the competition NOT named AMD.
As is usually the case, Davies described the state of processor technology with an emphasis on power efficiency and the importance of designing with that future in mind. One of the interesting points was shown in regard to the "bitter reality" of core-type performance and the projected DECREASE we will see from 2012 onward due to leakage concerns as we progress to 10nm and even 7nm technologies.
The idea of dark silicon "refers to the huge swaths of silicon transistors on future chips that will be underused because there is not enough power to utilize all the transistors at the same time" according to this article over at physorg.com. As the process technology gets smaller then the areas of dark silicon increase until the area of the die that can be utilized at any one time might hit as low as 10% in 2020. Because of this, the need to design chips with many task-specific heterogeneous portions is crucial and both AMD and ARM on that track.
Those companies not on that path today, NVIDIA specifically and Intel as well, were addressed on the below slide when discussing GPU computing. Davies pointed out that if a company has a financial interest in the immediate success of only CPU or GPU then benchmarks will be built and shown in a way to make it appear that THAT portion is the most important. We have seen this from both NVIDIA and Intel in the past couple of years while AMD has consistently stated they are going to be using the best processor for the job.
Amdahl's Law is used in parallel computing to predict the theoretical maximum speed up using multiple processors. Davies reiterated what we have been told for some time that if only 50% of your application can actually BE parallelized, then no matter how many processing cores you throw at it, it will only ever be 50% faster. The heterogeneous computing products of today and the future can address both the parallel computing and serial computing tasks with improvements in performance and efficiency and should result in better computing in the long run.
So while we didn't get the major announcement from ARM and AMD that we might have been expecting, the fact that ARM would come up and share a stage with AMD reiterates the message of the Fusion Developer Summit quite clearly: a combined and balanced approach to processing might not be the sexiest but it is very much the correct one for consumers.

That interface doesn’t look very silvery, or light.
I think the real message here is that when you invest (through time, money, or otherwise) in a proprietary infrastructure you need to expect that you have no real recourse should the owner work against you; you voided all recourse except for what is explicitly contractually bound to you. In the case of an open, particularly copyleft, platform: should support from the original owners be absent or insufficient you are legally allowed to take over provided that right is also granted by you. Often it may still be worthwhile to invest in proprietary platforms, but remember, you give up your right to maintain your dependencies. All your dependent art is relying on your trust in the platform owner, and you have no legal recourse, because you gave it away.
Do you have any comments on this? Discuss below.

It is that time of year again where the staff at PC Perspective wades through the moist air of Taipei, Taiwan to bring you the latest news, videos and updates from the world of technology and computing hardware. This marks my 10th appearance on the island of Taiwan, but Ken's first so it should be an interesting experience for both of us.
Yes, this scary girl is here again too.
This year we have a surprising amount of expected hardware to investigate starting with an onslaught of AMD-based technology. The AMD 990FX chipset will be out and about in force from the likes of ASUS, MSI, ECS and others while the Fusion APUs will be flaunted in notebooks and likely even some "surprise" Llano designs. Intel's Z68 chipset, though already launched, will still be a focus but the company will surprise many with a dramatic move into the world of mobile computing with the Atom line.
Temperatures are high but so is the excitement!!

Our Tech Talk Forum is a great place to hang out and discuss general technology questions, such as the eternal question of which screwdriver to use, since we can't get hold of a working Sonic Screwdriver, do you have a preferred electric screwdriver or do you prefer the traditional one like mpulliam and I do? Perhaps you are more interested in moving to SoCal where NewEgg is apparently opening up a pick up location.
Head over to the Processor Forum for speculation on Bulldozer, since the recent leaks have given us a bit more information; or maybe a laugh at the Apple fanatics and the price they pay for the same hardware we use? Especially considering that while some of their designs are nice, they can never match the imagination of a dedicated modder!
There is a lot more inside, take a walk through the forums and see what you can find or even better ... what you can offer! For a more laid back way to catch up on the latest tech news you should catch the new PC Perspective Podcast, #156 even has Ryan in it!

In a continuation of our effort to embrace and report on the open-source community, PC Perspective has contacted another very interesting Open-Source project. This week we selected Ubuntu and their Manager of the Ubuntu Kernel Team, Pete Graner

The self-described beginning of Ubuntu:
Linux was already established as an enterprise server platform in 2004. But free software was still not a part of everyday life for most computer users. That's why Mark Shuttleworth gathered a small team of developers from one of the most established Linux projects – Debian - and set out to create an easy-to-use Linux desktop, Ubuntu.
The vision for Ubuntu is part social and part economic: free software, available free of charge to everybody on the same terms, and funded through a portfolio of services provided by Canonical.
If you would like to learn more about Ubuntu please click here.
Ubuntu also lists its features as the following:
- A fresh look
The launcher: Get easy access to your favourite tools and applications with our lovely new launcher. You can hide and reveal it, add and remove apps and keep track of your open windows.
The dash: Our new dash offers a great way to get to your shortcuts and search for more apps and programs. So you can get fast access to your email, music, pictures and much more.
Workspaces: Our handy workspaces tool gives you a really easy way to view and move between multiple windows and applications.
You can surf in safety with Ubuntu – confident that your files and data will stay protected. A built-in firewall and virus protection come as standard. And if a potential threat appears, we provide automatic updates which you can install in a single click. You get added security with AppArmor, which protects your important applications so attackers can’t access your system. And thanks to Firefox and gnome-keyring, Ubuntu helps you keep your private information private. So whether it’s accessing your bank account or sharing sensitive data with friends or colleagues, you’ll have peace of mind when you need it the most.
Ubuntu works brilliantly with a range of devices. Simply plug in your mp3 player, camera or printer and you’ll be up and running straight away. No installation CDs. No fuss. And it’s compatible with Windows too! So you can open, edit and share Microsoft Office documents stress-free.
Ubuntu loads quickly on any computer, but it's super-fast on newer machines. With no unnecessary programs and trial software slowing things down, booting up and opening a browser takes seconds. Unlike other operating systems that leave you staring at the screen, waiting to get online. And Ubuntu won’t grow sluggish over time. It’s fast. And it stays fast.
Accessibility is central to the Ubuntu philosophy. We believe that computing is for everyone regardless of nationality, race, gender or disability. Fully translated into 25 languages, Ubuntu also includes essential assistive technologies, which are, of course, completely free. We recommend the Ubuntu classic desktop experience for users with particular accessibility requirements.

I have used Ubuntu almost as long as I have been using Fedora. Ubuntu has been my go to Linux distrobution since Wartty Warthog. I have installed Ubuntu on laptops, family members computers, and I even went 100% Ubuntu for a year. In my experience, any and all of my questions could be answered by Documentation, Community, and Launchpad.
Now that you have a brief idea about Ubuntu, lets get to the interview:
