According to VR-Zone, AMD has reworked their business, last Thursday, sorting each of their projects into two divisions and moving some executives around. The company is now segmented into the "Enterprise, Embedded, and Semi-Custom Business Group", and the "Computing and Graphics Business Group". The company used to be divided between "Computing Solutions", which handled CPUs, APUs, chipsets, and so forth, "Graphics and Visual Solutions", which is best known for GPUs but also contains console royalties, and "All Other", which was... everything else.
Lisa Su, former general manger of global business, has moved up to Chief Operating Officer (COO), along with other changes.
This restructure makes sense for a couple of reasons. First, it pairs some unprofitable ventures with other, highly profitable ones. AMD's graphics division has been steadily adding profitability to the company while its CPU division has been mostly losing money. Secondly, "All Other" is about a nebulous as a name can get. Instead of having three unbalanced divisions, one of which makes no sense to someone glancing at AMD's quarterly earnings reports, they should now have two, roughly equal segments.
At the very least, it should look better to an uninformed investor. Someone who does not know the company might look at the sheet and assume that, if AMD divested from everything except graphics, that the company would be profitable. If, you know, they did not know that console contracts came into their graphics division because their compute division had x86 APUs, and so forth. This setup is now more aligned to customers, not products.

It should not pass anyone's smell test but it apparently does, according to tweets and other articles. Officially, the TrueCrypt website (which redirects to their SourceForge page) claims that, with the end of Windows XP support (??), the TrueCrypt development team wants users to stop using their software. Instead, they suggest a switch to BitLocker, Mac OSX built-in encryption, or whatever random encryption suite comes up when you search your Linux distro's package manager (!?). Not only that, but several versions of Windows (such as 7 Home Premium) do not have access to BitLocker. Lastly, none of these are a good solution for users who want a single encrypted container across multiple OSes.
A new version (don't use it!!!) called TrueCrypt 7.2 was released and signed with their private encryption key.
The developers have not denied the end of support, and its full-of-crap reason. (Seriously, because Microsoft deprecated Windows XP almost two months ago, they pull support for a two year old version now?)
They have also not confirmed it. They have been missing since at least "the announcement" (or earlier if they were not the ones who made it). Going missing and unreachable, the day of your supposedly gigantic resignation announcement, does not support the validity of that announcement.
To me, that is about as unconfirmed as you can get.
Still, people are believing the claims that TrueCrypt 7.1a is not secure. The version has been around since February 2012 and, beyond people looking at its source code, has passed a significant portion of a third-party audit. Even if you believe the website, it only says that TrueCrypt will not be updated for security. It does not say that TrueCrypt 7.1a is vulnerable to any known attack.
In other words, the version that has been good enough for over two years, and several known cases of government agencies being unable to penetrate it, is probably as secure today as it was last week.
"The final version", TrueCrypt 7.2, is a decrypt-only solution. It allows users to unencrypt existing vaults, although who knows what else it does, to move it to another solution. The source code changes have been published, and they do not seem shady so far, but since we cannot even verify that their private key has not leaked, I wouldn't trust it. A very deep compromise could make finding vulnerabilities very difficult.
So what is going on? Who knows. One possibility is that they were targeted for a very coordinated hack, one which completely owned them and their private key, performed by someone(s) who spent a significant amount of time modifying a fake 7.2 version. Another possibility is that they were legally gagged and forced to shut down operations, but they managed to negotiate a method for users to decrypt existing data with a neutered build.
One thing is for sure, if this is a GoG-style publicity stunt, I will flip a couple of tables.
We'll see. ┻━┻ \_(ツ)_/ ┻━┻
The AMD Argument
Earlier this week, a story was posted in a Forbes.com blog that dove into the idea of NVIDIA GameWorks and how it was doing a disservice not just on the latest Ubisoft title Watch_Dogs but on PC gamers in general. Using quotes from AMD directly, the author claims that NVIDIA is actively engaging in methods to prevent game developers from optimizing games for AMD graphics hardware. This is an incredibly bold statement and one that I hope AMD is not making lightly. Here is a quote from the story:
Gameworks represents a clear and present threat to gamers by deliberately crippling performance on AMD products (40% of the market) to widen the margin in favor of NVIDIA products. . . . Participation in the Gameworks program often precludes the developer from accepting AMD suggestions that would improve performance directly in the game code—the most desirable form of optimization.
The example cited on the Forbes story is the recently released Watch_Dogs title, which appears to show favoritism towards NVIDIA GPUs with performance of the GTX 770 ($369) coming close the performance of a Radeon R9 290X ($549).
It's evident that Watch Dogs is optimized for Nvidia hardware but it's staggering just how un-optimized it is on AMD hardware.
Watch_Dogs is the latest GameWorks title released this week.
I decided to get in touch with AMD directly to see exactly what stance the company was attempting to take with these kinds of claims. No surprise, AMD was just as forward with me as they appeared to be in the Forbes story originally.
The AMD Stance
Central to AMD’s latest annoyance with the competition is the NVIDIA GameWorks program. First unveiled last October during a press event in Montreal, GameWorks combines several NVIDIA built engine functions into libraries that can be utilized and accessed by game developers to build advanced features into games. NVIDIA’s website claims that GameWorks is “easy to integrate into games” while also including tutorials and tools to help quickly generate content with the software set. Included in the GameWorks suite are tools like VisualFX which offers rendering solutions like HBAO+, TXAA, Depth of Field, FaceWorks, HairWorks and more. Physics tools include the obvious like PhysX while also adding clothing, destruction, particles and more.

Tagged: ultraviolet, mozilla, DRM, Adobe Access, Adobe
Needless to say, DRM is a controversial topic and I am clearly against it. I do not blame Mozilla. The non-profit organization responsible for Firefox knew that they could not oppose Chrome, IE, and Safari while being a consumer software provider. I do not even blame Apple, Google, and Microsoft for their decisions, either. This problem is much bigger and it comes down to a total misunderstanding of basic mathematics (albeit at a ridiculously abstract and applied level).
Simply put, piracy figures are meaningless. They are a measure of how many people use content without paying (assuming they are even accurate). You know what is more useful? Sales figures. Piracy figures are measurements, dependent variables, and so is revenue. Measurements cannot influence other measurements. Specifically, measurements cannot influence anything because they are, themselves, the result of influences. That is what "a measure" is.
Implementing DRM is not a measurement, however. It is a controllable action whose influence can be recorded. If you implement DRM and your sales go down, it hurt you. You may notice piracy figures decline. However, you should be too busy to care because you should be spending your time trying to undo the damage you did to your sales! Why are you looking at piracy figures when you're bleeding money?
I have yet to see a DRM implementation that correlated with an increase in sales. I have, however, seen some which correlate to a massive decrease.
The thing is, Netflix might know that and I am pretty sure that some of the web browser companies know that. They do not necessarily want to implement DRM. What they want is content and, surprise, the people who are in charge of the content are definitely not enlightened to that logic. I am not even sure if they realize that the reason why content is pirated before their release dates is because they are not leaked by end users.
But whatever. Technical companies, who want that content available on their products, are stuck finding a way to appease those content companies in a way that damages their users and shrinks their potential market the least. For Mozilla, this means keeping as much open as possible.
Since they do not have existing relationships with Hollywood, Adobe Access will be the actual method of displaying the video. They are clear to note that this only applies to video. They believe their existing relationships in text, images, and games will prevent the disease from spreading. This is basically a plug-in architecture with a sandbox that is open source and as strict as possible.
This sandbox is intended to prevent a security vulnerability from having access to the host system, give a method of controlling the DRM's performance if it hitches, and not allow the DRM to query the machine for authentication. The last part is something they wanted to highlight, because it shows their effort to protect the privacy of their users. They also imply a method for users to opt-out but did not go into specifics.
As an aside, Adobe will support their Access DRM software on Windows, Mac, and Linux. Mozilla is pushing hard for Android and Firefox OS, too. According to Adobe, Access DRM is certified for use with Ultraviolet content.
I accept Mozilla's decision to join everyone else but I am sad that it came to this. I can think of only two reasons for including DRM: for legal (felony) "protection" under the DMCA or to make content companies feel better while they slowly sink their own ships chasing after numbers which have nothing to do with profits or revenue.
Ultimately, though, they made a compromise. That is always how we stumble and fall down slippery slopes. I am disappointed but I cannot suggest a better option.

Tagged: mozilla, net neutrality
Recently, the FCC has been moving to give up Net Neutrality. Mozilla, being dedicated to the free (as in speech) and open internet, has offered a simple compromise. Their proposal is that the FCC classifies internet service providers (ISPs) as common carriers on the server side, forcing restrictions on them to prevent discrimination of traffic to customers, while allowing them to be "information services" to consumers.
In other words, force ISPs to allow services to have unrestricted access to consumers, without flipping unnecessary tables with content distribution (TV, etc.) services. Like all possibilities so far, it could have some consequences, however.
"Net Neutrality" is a hot issue lately. Simply put, the internet gives society an affordable method of sharing information. How much is "just information" is catching numerous industries off guard, including ones which Internet Service Providers (ISPs) participate in (such as TV and Movie distribution), and that leads to serious tensions.
On the one hand, these companies want to protect their existing business models. They want consumers to continue to select their cable and satellite TV packages, on-demand videos, and other services at controlled profit margins and without the stress and uncertainty of competing.
On the other hand, if the world changes, they want to be the winner in that new reality. Yikes.
A... bad... photograph of Mozilla's "UP" anti-datamining proposal.
Mozilla's proposal is very typical of them. They tend to propose compromises which divides an issue such that both sides get the majority of their needs. Another good example is "UP", or User Personalization, which tries to cut down on data mining by giving a method for the browser to tell websites what they actually want to know (and let the user tell the browser how much to tell them). The user would compromise, giving the amount of information they find acceptable, so the website would compromise and take only what they need (rather than developing methods to grab anything and everything they can). It feels like a similar thing is happening here. This proposal gives users what they want, freedom to choose services without restriction, without tossing ISPs into "Title II" common carrier altogether.
Of course, this probably comes with a few caveats...
The first issue that pops in my mind is, "What is a service?". I see this causing problems for peer-to-peer applications (including BitTorrent Sync and Crashplan, excluding Crashplan Central). Neither endpoint would necessarily be classified as "a server", or at least convince a non-technical lawmaker that is the case, and thus ISPs would not need to apply common carrier restrictions to them. This could be a serious issue for WebRTC. Even worse, companies like Google and Netflix would have no incentive to help fight those battles -- they're legally protected. It would have to be defined, very clearly, what makes "a server".
Every method will get messy for someone. Still, the discussion is being made.

Tagged: TDP, Athlon 5350, Asus AM1I-A, amd, AM1
If I had one regret about my AM1 review that posted a few weeks ago, it was that I used a pretty hefty (relatively speaking) 500 watt power supply for a part that is listed at a 25 watt TDP. Power supplies really do not hit their efficiency numbers until they are at least under 50% load. Even the most efficient 500 watt power supply is going to inflate the consumption numbers of these diminutive parts that we are currently testing.
Keep it simple... keep it efficient.
Ryan had sent along a 60 watt notebook power supply with an ATX cable adapter at around the same time as I started testing on the AMD Athlon 5350 and Asus AM1I-A. I was somewhat roped into running that previously mentioned 500 watt power supply due to comparative reasons. I was using a 100 watt TDP A10-6790 APU with a pretty loaded Gigabyte A88X based ITX motherboard. That combination would have likely fried the 60 watt (12v x 5A) notebook power supply under load.
Now that I had a little extra time on my hands, I was able to finally get around to seeing exactly how efficient this little number could get. I swapped the old WD Green 1 TB drive for a new Samsung 840 EVO 500 GB SSD. I removed the BD-ROM drive completely from the equation as well. Neither of those parts uses a lot of wattage, but I am pushing this combination to go as low as I possibly can.
The results are pretty interesting. At idle we see the 60 watt supply (sans spinning drive and BD-ROM) hitting 12 watts as measured from the wall. The 500 watt power supply and those extra pieces added another 11 watts of draw. At load we see a somewhat similar numbers, but not nearly as dramatic as at idle. The 60 watt system is drawing 29 watts while the 500 watt system is at 37 watts.
So how do you get from a 60 watt notebook power adapter to ATX standard? This is the brains behind the operation.
The numbers for both power supplies are both good, but we do see that we get a nice jump in efficiency from using the smaller unit and a SSD instead of a spinning drive. Either way, the Athlon 5350 and AMD AM1 infrastructure sip power as compared to most desktop processors.

Tagged: valve, steam
Valve does not release sales or hours played figures for any game on Steam and it is rare to find a publisher who will volunteer that information. That said, Steam user profiles list that information on a per-account basis. If someone, say Ars Technica, had access to sufficient server capacity, say an Amazon Web Services instance, and a reasonable understanding of statistics, then they could estimate.
If interested, I would definitely look through the original editorial for all of its many findings. Here, if you let me (and you can't stop me even if you don't), I would like to add my own analysis on a specific topic. The Elder Scrolls V: Skyrim on the PC, according to VGChartz, sold 3.42 million copies on at retail, worldwide. The thing is, Steamworks was required for every copy sold at retail or online. According to Ars Technica's estimates, 5.94 million copies were registered with Steam.
5.94 minus 3.42 is 2.52 million copies sold digitally. Almost a third of PC sales were made through Steam and other digital distribution platforms. Also, this means that the PC was the game's second-best selling platform, ahead of the PS3 (5.43m) and behind the Xbox 360 (7.92m), minus any digital sales on those platforms if they exist, of course. Despite its engine being programmed in DirectX 9, it is still a fairly high-end game. That is a fairly healthy install base for decent gaming PCs.
