Tagged: web browser, Malware, IE10
If you consider your browser security based solely on whether it will allow you to manually download a malicious executable: IE10 is the best browser ever!
Rod Trent over at Windows IT Pro seems to believe this when NSS labs released their report, "Socially Engineered Malware Blocking". In this report, Internet Explorer blocked the user from downloading nearly all known malware (clarification: all known malware within the test). Google Chrome came in second place with a little less than 17% fail rate and the other browsers were quite far behind with approximately a 90% failure rate.
Based on that one metric alone, Rod Trent used a cutesy chess image to proclaim IE the... king... of the hill. Not only that, he suggests Safari, Opera, and Firefox consider "shuttering their doors." After about a decade of Internet Explorer suffering from countless different and unique vectors of exploitation, now is the time to proclaim a victor for attacks which require explicit user action?
Buckle in, readers, it's a rant.
Firstly, this reminds me a little bit of Microsoft Security Essentials. Personally, I use it, because it provides enough protection for me. Unlike its competitors, MSE has next to no false positives because almost ignores zero-day exploits. The AV package drew criticism from lab tests which test zero-day exploits. Microsoft Security Essentials was ranked second-worst by this metric.
Well, time to shutter your doors Micr... oh wait Rod Trent lauded it as award-winning. Huh...
But while we are on the topic of false positives, how do you weigh those in your grading of a browser? According to the report, and common sense, achieving pure success in this metric is dead simple if you permit your browser to simply block every download, good or bad.
If a 100% false positive acceptance rate is acceptable, it is trivial to protect users from all malicious download. With just a few lines of code, Firefox, Safari, and Opera could displace Internet Explorer and Chrome as the leaders of protection against socially engineered malware. However, describing every download as "malicious" would break the internet. Finding a balance between accuracy and safety is the challenge for browsers at the front of protection technology.
A browser that is capable of blocking malware without blocking legitimate content would certainly be applause-worthy. I guess time will tell whether Internet Explorer 10 is able to walk the balance, or whether it will just be a nuisance like the first implementations of UAC.
OK, Google did actually release exactly one native Windows application at Google I/O: It's called Android Studio, an application that helps developers create apps that run on Android, Google’s answer to Windows. But don’t worry, Microsoft fans: Internet Explorer (IE) flags the Android Studio download as potential malware.
Ah crap... that was quick.
Now to be fair, Internet Explorer 10 and later have been doing things right. I am glad to see Microsoft support standards and push for an open web after so many years. This feature helps protect users from their own complacency.
Still, be careful when you call checkmate: some places may forfeit your credibility.

I cannot do it captain! I don't have the not enough power!
We have been discussing the ultra-low power state of Haswell processors for a little over a week and how it could be detrimental to certain power supplies. Power supply manufacturers never quite expected that you could have as little as a 0.05 Amp (0.6W) draw on the 12V rail without being off. Since then, companies such as Enermax started to list power supplies which have been tested and are compliant with the new power requirements.

Above is Corsair's slightly incomplete chart as of the time it was copied from their website, 3:30pm on May 10th, 2013; so far it is coming up all good. Their blog should be updated as new products get validated for the new C6 and C7 CPU sleep states.
The best part of this story is just how odd it is given the race to arc-welding (it's not a podcast so you can't Bingo! hahaha!) supplies we have been experiencing over the last several years. Simply put, some companies never thought that component manufacturers such as Intel would race to the bottom of power draws.

Update: Did you miss the live stream? Watch the on-demand replay below and learn all about the Frame Rating system, FCAT, input latency and more!!
I know, based solely on the amount of traffic and forum discussion, that our readers have really adopted and accepted our Frame Rating graphics testing methodology. Based on direct capture of GPU output via an external system and a high end capture card, our new systems have helped users see GPU performance a in more "real-world" light that previous benchmarks would not allow.
I also know that there are lots of questions about the process, the technology and the results we have shown. In order to try and address these questions and to facilitate new ideas from the community, we are hosting a PC Perspective Live Stream on Thursday afternoon.
Joining me will be NVIDIA's Tom Petersen, a favorite of the community, to talk about NVIDIA's stance on FCAT and Frame Rating, as well as just talk about the science of animation and input.
The primary part of this live stream will be about education - not about bashing one particular product line or talking up another. And part of that education is your ability to interact with us live, ask questions and give feedback. During the stream we'll be monitoring the chat room embedded on http://pcper.com/live and I'll be watching my Twitter feed for questions from the audience. The easiest way to get your question addressed though will be to leave a comment or inquiry here in this post below. It doesn't require registration and this will allow us to think about the questions before hand, giving it a better chance of being answered during the stream.
Frame Rating and FCAT Live Stream
11am PT / 2pm ET - May 9th
So, stop by at 2pm ET on Thursday, May 9th to discuss the future of graphics performance and benchmarking!

Tagged: Volcanic Islands, radeon, ps4, amd
So the Southern Islands might not be entirely stable throughout 2013 as we originally reported; seismic activity being analyzed suggests the eruption of a new GPU micro-architecture as early as Q4. These Volcanic Islands, as they have been codenamed, should explode onto the scene opposing NVIDIA's GeForce GTX 700-series products.
It is times like these where GPGPU-based seismic computation becomes useful.
The rumor is based upon a source which leaked a fragment of a slide outlining the processor in block diagram form and specifications of its alleged flagship chip, "Hawaii". Of primary note, Volcanic Islands is rumored to be organized with both Serial Processing Modules (SPMs) and a Parallel Compute Module (PCM).
So apparently a discrete GPU can have serial processing units embedded on it now.
Heterogeneous Systems Architecture (HSA) is a set of initiatives to bridge the gap between massively parallel workloads and branching logic tasks. We usually make reference to this in terms of APUs and bringing parallel-optimized hardware to the CPU. In this case, we are discussing it in terms of bringing serial processing to the discrete GPU. According to the diagram, the chip within would contain 8 processor modules each with two processing cores and an FPU for a total of 16 cores. There does not seem to be any definite identification whether these cores would be based upon their license to produce x86 processors or their other license to produce ARM processors. Unlike an APU, this is heavily skewed towards parallel computation rather than a relatively even balance between CPU, GPU, and chipset features.
Now of course, why would they do that? Graphics processors can do branching logic but it tends to sharply cut performance. With an architecture such as this, a programmer might be able to more efficiently switch between parallel and branching logic tasks without doing an expensive switch across the motherboard and PCIe bus between devices. Josh Walrath suggested a server containing these as essentially add-in card computers. For gamers, this might help out with workloads such as AI which is awkwardly split between branching logic and massively parallel visibility and path-finding tasks. Josh seems skeptical about this until HSA becomes further adopted, however.
Still, there is a reason why they are implementing this now. I wonder, if the SPMs are based upon simple x86 cores, how the PS4 will influence PC gaming. Technically, a Volcanic Island GPU would be an oversized PS4 within an add-in card. This could give AMD an edge, particularly in games ported to the PC from the Playstation.
This chip, Hawaii, is rumored to have the following specifications:
- 4096 stream processors
- 16 serial processor cores on 8 modules
- 4 geometry engines
- 256 TMUs
- 64 ROPs
- 512-bit GDDR5 memory interface, much like the PS4.
20 nm Gate-Last silicon fab process
- Unclear if TSMC or "Common Platform" (IBM/Samsung/GLOBALFOUNDRIES)
Softpedia is also reporting on this leak. Their addition claims that the GPU will be designed on a 20nm Gate-Last fabrication process. While gate-last is considered to be not worth the extra effort in production, Fully Depleted Silicon On Insulator (FD-SOI) is apparently "amazing" on gate-last at 28nm and smaller fabrication. This could mean that AMD is eying that technology and making this design with intent of switching to an FD-SOI process, without a large redesign which an initially easier gate-first production would require.
Well that is a lot to process... so I will leave you with an open question for our viewers: what do you think AMD has planned with this architecture, and what do you like and/or dislike about what your speculation would mean?

If, on the other hand, you wish to see an example of a large application compiled for the browser: would Unreal Engine 3 suffice?
Clearly a computer hardware website would take the effort required to run a few benchmarks, and we do not disappoint. Epic Citadel was run in its benchmark mode in Firefox 20.0.1, Firefox 22.0a2, and Google Chrome; true, it was not run for long on Chrome before the tab crashed, but you cannot blame me for trying.
Each benchmark was run at full-screen 1080p "High Performance" settings on a PC with a Core i7 3770, a GeForce GTX 670, and more available RAM than the browser could possibly even allocate. The usual Firefox framerate limit was removed; they were the only tab open on the same fresh profile; the setting layout.frame_rate.precise was tested in both positions because I cannot keep up what the state of requestAnimationFrame callback delay is; and each scenario was performed twice and averaged.
- layout.frame_rate.precise true: 54.7 FPS
- layout.frame_rate.precise false: 53.2 FPS
Firefox 22.0a2 (asm.js)
- layout.frame_rate.precise true: 147.05 FPS
- layout.frame_rate.precise false: 144.8 FPS
Google Chrome 26.0.1410.64
It is also very enticing for Epic as well. A little over a month ago, Mark Rein and Tim Sweeney of Epic were interviewed by Gamasutra about HTML5 support for Unreal Engine. Due in part to the removal of UnrealScript in favor of game code being scripted in C++, Unreal Engine 4 will support HTML5. They are working with Mozilla to make the browser a reasonable competitor to consoles; write once, run on Mac, Windows, Linux, or anywhere compatible browsers can be found. Those familiar with my past editorials know this excites me greatly.
So what do our readers think? Comment away!
Good effort goes a long way
The wait has been long and anxious for Heart of the Swarm, the expansion to 2010's StarCraft 2: Wings of Liberty. Blizzard originally hinted at a very rapid release schedule which did not exactly come to fruition. The nearly three years of development time for Heart of the Swarm is longer than a single studio spends on a full Call of Duty title; although, one could make a very credible argument that a Blizzard expansion requires more effort to create than said complete Call of Duty title.
But as Duke Nukem Forever demonstrated, a long time in development does not guarantee a fully baked product coming out the other end.
Blizzard games have always been highly entertaining albeit without deep artistic substance; their games are not first on the list for a university literature syllabus. But, there is a lot of room in life for engaging entertainment. In terms of the PC, Blizzard has always been one of the leading developers for the platform; they know how to deliver an exceptional PC experience if they choose to.

UPDATE 4/26/13: We are extremely excited to see that we have met our first goal for our Indiegogo project! We are eternally grateful for our fans and readers that are supporting us in this endeavor. We are going to start putting together orders for the set materials and I am very excited about the direction this is pointing us in. There is still room to improve the project though and we have lots of great perks available for those of you that are still looking to contribute to the cause! Oh, and we should have our T-shirt design ready early next week as well. Thank you EVERYONE for reading PC Perspective!!
And for those of you looking for a bit more insight into our total goals, here is another mock up of the set!
Yesterday evening, the team at PC Perspective launched a project that will help us grow and expand our coverage of technology and computer hardware. Using the crowd funding service called Indiegogo.com, we are doing a fund drive to help improve the quality of our video content and enable us to do more, unique styles of content.
If you are anything like us, you love technology. Motherboards, graphics cards, processors, SSDs, monitors, laptops, tablets, cell phones and more. And you also love reading about them, hearing about them and seeing them, dissecting them and finding out what makes them tick.
I am confident that high quality video content is the future of our medium and while we have been able to do quite a lot with the basic technology and setup we have here today, my goal is to be able to bring the readers regular, high quality video content on all aspects of technology. We want to not only have video reviews for products but we want to be able to do near-daily content updates on the news of the day while balancing that with long-form interviews of personalities that make the industry function. We have dabbled in some of these content types and the responses have been great, but we need a higher quality setup to really do it right.
Our goal with this project is to build the funds necessary to turn our office in Florence, KY into a high tech video production outlet that starts with a quality set design and better quality equipment.
Other than supporting one of your favorite online outlets, we have also lined up some sweet perks for contributors to our project. We have ad-free versions of the site, Tshirts and access to the PC Perspective Gold Club that has some pretty ridiculous giveaways! If you support us even further you can get some individual time with our team to tell us why you supported us, answer your questions or even join us for an episode of the PC Perspective Podcast!
Come visit the offices, join the process of creating a new show or make fun of Josh's laugh in person - it's all possible!
So if you have the means and you want to support our cause, if you have enjoyed any of our articles, podcasts or video reviews, consider helping to fund our project!

Operators are standing by...
Of course Apple is not a primary manufacturer of LCD panels; like everyone else, they buy their panels from someone like LG. Due to how much Apple loves IPS technology, which I cannot blame them for, they in fact do purchase their displays from LG.
If you have an itchy soldering iron, so can you.
According to EmertHacks, the LG part number for retina iPad screens is LP097QX1-SPA1. The blog post states that he could find the panel for as cheap as $55, but my own digging game up with costs between $60 and $200 plus shipping. These panels are mostly destined to iPad repair shops, but you can give it a better home.
With under $20 of other parts, this panel could be attached to a DisplayPort connection. All said and done, you could have a 2048x1536 9.7" display with an 800:1 static contrast ratio for about $70.

Tagged: windows, start button, Metro
The latest rumors, based on registry digging and off-the-record testimony, claims that Windows 8.1 will including the option of booting directly into the desktop. A bold claim such as this requires some due diligence. Comically, the attempts to confirm this rumor has unearthed another: the start button, but not necessarily the start menu, could return. On the record, Microsoft also wants to be more open to customer feedback. Despite these recent insights into the future of Windows, all's quiet with the worst aspect of modernization.
Mary Jo Foley, contributor to ZDNet and very reliable bullcrap filter for Microsoft rumors, learned from a reliable source that the Start Button might have a place in the modern Windows. Quite the catch while fishing to validate a different rumor; she was originally investigating whether Microsoft would consider allowing users to boot direct to desktop via recently unearthed registry keys. Allegedly both are being planned for at least some SKUs of Windows 8.1, namely the Professional and Enterprise editions.
But, as usual for Microsoft, the source emphasized, "Until it ships, anything can change." No-one was clear about the Start Button from a functional standpoint: would it be bound to display the Start Screen? Would it be something more?
Personally, I liked the modern Windows interface. Sure, it is messed up on the modern-side when it comes to multiple monitor support, but that can easily be fixed. As you will note, I am still actively boycotting everything beyond Windows 7 and this news will not change my mind. We are bickering over interface elements when the real concern is the deprecation of user control. Outside of the desktop: the only applications you can use are from the Windows Store or Windows Update; the only websites you can browse are ones which Internet Explorer can render; and the only administrator is Microsoft.
Imagine if Microsoft is told by a government that its citizens are not allowed encryption applications.
The Windows Store is clearly modeled by, and about as messed up as, the Xbox Marketplace. Even if your application gets certified, would Microsoft eventually determine that certification fees should be the burden of the developer? That is how it is on the Xbox with each patch demanding a price tag of about $40,000 after the first-one-free promotion. That would be pretty hard to swallow for an open-source application or a cute game that a teenage woman makes for her significant other as a Valentine's gift.
Microsoft's current Chief Financial Officer, Peter Klein, stated in his third quarter earnings release that Windows Blue, "Further advances the vision of Windows 8 as well as responds to customer feedback." Despite how abrupt this change would seem, the recent twitchy nature should not come as a surprise; Microsoft has had a tendency to completely change course on products for quite some time now. Mary Jo mentioned how Microsoft changed course on UAC but even that is a bad example; a better one is how Microsoft changed from its initial assertions that Windows 8 Developer Preview would not be shaped by customer feedback.
A lot has changed between Developer Preview and RTM.
Then again, we can hope that Microsoft associates this pain with love for the desktop. I would be comfortable with the modern Windows if we were given a guarantee that desktop x86 applications would forever be supported. I might even reconsider using and developing applications if they allow loading uncertified metro-style applications and commit to never removing that functionality.
I can get used to a new method of accessing my applications. I can never get used to a middle-man who only says "no". If Microsoft is all ears, I hope we make this point loud and clear.
