Corsair Clarifies Upcoming Investment Deal With Francisco Partners

Subject: General Tech | May 2, 2013 - 01:04 PM | Tim Verry
Tagged: private equity, investments, corsair

Corsair recently reached out to the technology community to clarify the news of a new investor interested in the company. It turns out that Corsair is in talks with a private equity firm called Francisco Partners. The PC peripherals company wants to expand by making strategic acquisitions of smaller companies in the gaming and audio industry. In order to do that, Corsair needs cash, and without going public, one way to get that is to go with a private equity firm.

Although it will not be official for a couple of weeks, according to Corsair, Francisco Partners will invest as much as $75 million in Corsair and become a shareholder in the privately-held company. The deal is simply a monetary one, with Francisco Partners providing needed cash in exchange for a share of the company. No management changes are planned, and the new investor will not become the majority shareholder according to Corsair.

Corsair recently acquired both gaming peripheral company Raptor Gaming and Simple Audio, a company that provides multi-room streaming audio solutions. Corsair plans to further aggressively pursue the gaming and music/audio markets in addition to its existing case, power supply, fan, and other PC peripheral lineups aimed at enthusiasts. I'm excited to see where Corsair goes from here as it grows and diversifies its business and product lines.

Microsoft Rumored To Be Working On Cloud-Based "Mohoro" Windows Desktop Service

Subject: General Tech | May 2, 2013 - 05:07 AM | Tim Verry
Tagged: windows, thin client, remote desktop, mohoro, microsoft, cloud computing, azure

Microsoft may be working on its own cloud-based desktop service according to sources speaking with ZDNet’s Mary Jo Foley. The rumored service codenamed “Mohoro” would build the Windows desktop SaaS (Software as a Service) solution on top of the company’s Windows Azure cloud computing platform. With Mohoro, Microsoft would provide Azure virtual machines running the Windows operating system. Users would then be able to remote into the desktop on any Internet connected computer or mobile device (with remote desktop support) and get access to their own desktop and applications.

The Windows desktop... coming soon to a cloud near you?

Windows Azure users can already run virtual machines with Linux or Windows OSes, but in the case of Windows Microsoft only allows server versions to be run. Incensing restrictions prevent users from loading consumer operating systems such as Windows XP, 7 or 8 onto the virtual machines. The rumored Mohoro service would apparently relax the licensing restrictions and allow businesses or consumers to deploy client operating systems running on the Azure VMs. It would basically take the need for enterprises to run their own hardware and move it to “the cloud” behind a Microsoft-run subscription service.

It is an interesting idea that I could see universities and businesses looking into. The Azure platform is actually pretty good, from what little testing I've done on it. However, I think that for many consumers a local install is preferable. Although syncing applications and files can be a pain if you have multiple machines, you retain control of your data and are not bound to needing an always-on Internet connection to access that data and run applications. Further, latency issues and bandwidth caps with home Internet connections make a paid-for Azure desktop less appealing to home users. I think Microsoft would have a hard-enough time selling users a subsciption for a local/traditional Windows installation, much less a subscription for an OS requiring an always-on Internet connection to use their computer.

Would you use an Azure-powered desktop as your main OS?

EFF Report Outlines Which Companies Stand Up For Users' Data Privacy Rights

Subject: General Tech | May 2, 2013 - 02:01 AM | Tim Verry
Tagged: Privacy, eff, data privacy, consumer rights

The Electronic Frontier Foundation (EFF) released its annual Who Has Your Back report, which highlights Internet companies that (do or do not) defend user’s online privacy rights. The EFF looks at the policies and actions of several major Internet companies, including ISPs, cloud storage, email, and social networks (among others). The companies are graded on various criteria such as whether the companies require a subpoena or warrant before releasing information, lobby congress for stricter data privacy laws, and defend their users’ privacy rights in court.

This year, the EFF found some surprising results. Google is no longer the leader of the pack due to no longer providing transparent data requests to users on the same level that it did in the past. Twitter and ISP Sonic.net are actually the top ranked companies. In a less surprising twist, Verizon is actually the worst company of the bunch along with MySpace with failing grades in each category! And that is just the tip of the spear, with companies like Apple and AT&T being worse than I thought and Foursquare and WordPress doing better than I expected.

Data privacy is of supreme importance, and i hope that these EFF reports prod all companies to do better (and note the companies that are doing right by their users). It is definitely worth a read. You can find the full report in PDF form here.

Do you use any of these services, and are you happy with their data privacy efforts?

Possible power supply issues for Intel Haswell CPUs

Subject: Cases and Cooling, Processors | May 1, 2013 - 03:07 PM | Ryan Shrout
Tagged: power supply, Intel, idle, haswell, c7, c6

I came across an interesting news story posted by The Tech Report this morning that dives into the possibility of problems with Intel's upcoming Haswell processors and currently available power supplies.  Apparently, the new C6 and C7 idle power states that give the new Haswell architecture benefits for low power scenarios place a requirement of receiving a 0.05 amps load on the 12V2 rail.  (That's just 50 milliamps!)  Without that capability, the system can exhibit unstable behavior and a quick look at the power supply selector on Intel's own website is only listing a couple dozen that support the feature. 

This table from VR-Zone, the source of the information initially, shows the difference between the requirements for 3rd (Ivy Bridge) and 4th generation (Haswell) processors.  The shift is an order of magnitude and is quite a dramatic change for PSU vendors.  Users of Corsair power supplies will be glad to know that among those listed with support on the Intel website linked above were mostly Corsair units!

A potential side effect of this problem might be that motherboard vendors simply disable those sleep states by default.  I don't imagine that will be a problem for PC builders anyway since most desktop users aren't really worried about the extremely small differences in power consumption they offer.  For mobile users and upcoming Haswell notebook designs the increase in battery life is crucial though and Intel has surely been monitoring those power supplies closely. 

I asked our in-house power supply guru, Lee Garbutt, who is responsible for all of the awesome power supply reviews on pcper.com, what he thought about this issue.  He thinks the reason more power supplies don't support it already is for power efficiency concerns:

Most all PSUs have traditionally required "some load" on the various outputs to attain good voltage regulation and/or not shut down. Not very many PSUs are designed yet to operate with no load, especially on the critical +12V output. One of the reasons for this is efficiency. Its harder to design a PSU to operate correctly with a very low load AND to deliver high efficiency. It would be easy just to add some bleed resistance across the DC outputs to always have a minimal load to keep voltage regulation under control but then that lowers efficiency.

A Duke Nukem obsession like no other

You might think you expressed your disappointment about the pile of garbage that was Duke Nukem Forever by posting scathing reviews online, but you have nothing on these modders who attempted to create the Duke we were all promised by modding Duke Nukem 3D.  If you still have the DN3D kicking around, or at least the DUKE3D.GRP file you can head to ModDB and download a 30MB mod which will expand Las Vegas far beyond the original game. Don't expect miracles, they can only reuse existing assets but they certainly impressed Rock, Paper, SHOTGUN who posted a trailer-ish movie of the mod in action.

"A group of modders have been busily attempting to rewrite history – by recreating the game that 2001 trailer suggested in good old Duke Nukem 3D. Given they suffered a degree of 3D Realms-esque hubris in their struggle to finish the thing, are these the first Method Developers?"

AMD Planning APU13 Developer Summit In San Jose, California

Tagged: hUMA, hsa, apu13, APU, amd, AFDS

AMD announced its third annual Developer Summit last week. Dubbed “APU13,” the upcoming summit is the AMD equivalent to NVIDIA’s GTC and is an annual event that brings together industry analysts, researchers, programmers, academics, and software/hardware companies pursuing heterogeneous computing technologies.

In previous years, the AMD Developer Summit has been the launchpad for C++ AMP and the HSA Foundation. This year’s Summit will continue that trend towards heterogeneous computing as well as look back over the year and provide updates on where the various HSA member companies are at as far as goals to move towards standards-based heterogenous computing.

In addition to keynote speeches from AMD and some of its partners, expect a great deal of presentations and workshops from researchers and programmers that are working on new programming models and hardware solutions to efficiently use CPU and GPU processors. More information on hUMA is one of the likely topics, for example. Discussion about upcoming hardware, process nodes, and products may also be on the table so far as it relates to the HSA theme. Considering the summit is called “APU13,” I also expect that AMD will reveal additional details on the company’s Kaveri APU as well as a look into its future product road map.

AMD is currently asking for presentation proposals from researchers in a number of HSA and technology-related fields including heterogeneous computing, cloud computing, web technologies, programming languages, gaming and graphics technologies, and software security. The lineup of presenters for the summit is still being worked out, and proposal papers will be accepted until May 10th with the winners being notified over the summer.

In all, AMD’s APU13 should be an exciting and intellectual event. Last year’s AMD Fusion Developer Summit (AFDS) was an interesting and fun event to cover, and I hope that APU13 will keep up the same momentum and interest in heterogeneous computing that AFDS started.

Zotac Announces Overclocked GTX TITAN AMP! Edition Graphics Card

Subject: Graphics Cards | May 1, 2013 - 05:41 AM | Tim Verry
Tagged: zotac, nvidia, gtx titan, AMP!

Zotac has announced a new GTX TITAN graphics card that will fall under the company’s AMP! Edition branding. This new Titan graphics card will feature factory overclocks on both the GPU and GDDR5 memory. However, due to NVIDIA’s restrictions, the Zotac GeForce GTX TITAN AMP! Edition does not feature a custom cooler or PCB.

The Zotac TITAN AMP! Edition card features a single GK110 GPU with 2,688 CUDA cores clocked at 902MHz base and 954MHz boost. That is a healthy boost over the reference TITAN’s 836MHz base and 876MHz boost clock speeds. Further, while Zotac’s take on the TITAN continues the reference specification’s 6GB of GDDR5 memory, it is impressively overclocked to 6,608Mhz (especially since Zotac has not changed the cooler). The GPU clocks might be able to be replicated by many of the reference cards though. For example, Ryan managed to get his card up to 992MHz boost in his review of the NVIDIA GTX TITAN.

The card has two DL-DVI, one HDMI, and one DisplayPort video output(s). The cooler, PCB, and PCI-E power specifications are still the same as the reference design. You can find more details on the heatsink in the TITAN review. Not allowing vendors to use custom coolers is disappointing and possibly limiting the factory GPU overclocks that they are able/willing to offer and support, but within that restriction the Zotac AMP! Edition looks to be a decent card so long as the (not yet announced) price premium over the $999 NVIDIA reference card is minimal.

AMD Releases FX CPU Refreshes

Tagged: amd, FX, vishera, bulldozer, FX-6350, FX-4350, FX-6300, FX-4300, 32 nm, SOI, Beloved

Today AMD has released two new processors that address the AM3+ market.  The FX-6350 and FX-4350 are two new refreshes of the quad and hex core lineup of processors.  Currently the FX-8350 is still the fastest of the breed, and there is no update for that particular number yet.  This is not necessarily a bad thing, but there are those of us who are still awaiting the arrival of the rumored “Centurion”.

These parts are 125 watt TDP units, which are up from their 95 watt predecessors.  The FX-6350 runs at 3.9 GHz with a 4.2 GHz boost clock.  This is up 300 MHz stock and 100 MHz boost from the previous 95 watt FX-6300.  The FX-4350 runs at 3.9 GHz with a 4.3 GHz boost clock.  This is 100 MHz stock and 300 MHz boost above that of the FX-4300.  What is of greater interest here is that the L3 cache goes from 4 MB on the 4300 to 8 MB on the 4350.  This little fact looks to be the reason why the FX-4350 is now a 125 watt TDP part.

It has been some two years since AMD started shipping 32 nm PD-SOI/HKMG products to the market, and it certainly seems as though spinning off GLOBALFOUNDRIES has essentially stopped the push to implement new features into a process node throughout the years.  As many may remember, AMD was somewhat famous for injecting new process technology into current nodes to improve performance, yields, and power characteristics in “baby steps” type fashion instead of leaving the node as is and making a huge jump with the next node.  Vishera has been out for some 7 months now and we have not really seen any major improvement in regards to performance and power characteristics.  I am sure that yields and bins have improved, but the bottom line is that this is only a minor refresh and AMD raised TDPs to 125 watts for these particular parts.

The FX-6350 is again a three module part containing six cores.  Each module features 2 MB of L2 cache for a total of 6 MB L2 and the entire chip features 8 MB of L3 cache.  The FX-4350 is a two module chip with four cores.  The modules again feature the same 2 MB of L2 cache for a total of 4 MB active on the chip with the above mentioned 8 MB of L3 cache that is double what the FX-4300 featured.

Perhaps soon we will see updates on FM2 with the Richland series of desktop processors, but for now this refresh is all AMD has at the moment.  These are nice upgrades to the line.  The FX-6350 does cost the same as the FX-6300, but the thinking behind that is that the 6300 is more “energy efficient”.  We have seen in the past that AMD (and Intel for that matter) does put a premium on lower wattage parts in a lineup.  The FX-4350 is $10 more expensive than the 4300.  It looks as though the FX-6350 is in stock at multiple outlets but the 4350 has yet to show up.

These will fit in any modern AM3+ motherboard with the latest BIOS installed.  While not an incredibly exciting release from AMD, it at least shows that they continue to address their primary markets.  AMD is in a very interesting place, and it looks like Rory Read is busy getting the house in order.  Now we just have to see if they can curve back their cost structure enough to make the company more financially stable.  Indications are good so far, but AMD has a long ways to go.  But hey, at least according to AMD the FX series is beloved!

hUMA has come with a weapon to slay the memory latency dragon

Subject: General Tech | April 30, 2013 - 01:23 PM | Jeremy Hellstrom
Tagged: Steamroller, piledriver, Kaveri, Kabini, hUMA, hsa, GCN, bulldozer, APU, amd

AMD may have united GPU and CPU into the APU but one hurdle had remained until now, the the non-uniformity of memory access between the two processors.  Today we learned about one of the first successful HAS projects called Heterogeneous Uniform Memory Access, aka hUMA, which will appear in the upcoming Kaveri chip family.   The use of this new technology will allow the on-die CPU and GPU to access the same memory pool, both physical and virtual and any data passed between the two processors will remain coherent.  As The Tech Report mentions in their overview hUMA will not provide as much of a benefit to discrete GPUs, while they will be able to share address space the widely differing clock speeds between GDDR5 and DDR3 prevent unification to the level of an APU.

Make sure to read Josh's take as well so you can keep up with him on the Podcast.

"At the Fusion Developer Summit last June, AMD CTO Mark Papermaster teased Kaveri, AMD's next-generation APU due later this year. Among other things, Papermaster revealed that Kaveri will be based on the Steamroller architecture and that it will be the first AMD APU with fully shared memory.

Last week, AMD shed some more light on Kaveri's uniform memory architecture, which now has a snazzy marketing name: heterogeneous uniform memory access, or hUMA for short."

New Ubuntu 13.04 Release Upgrades Unity, Ditches Wubi, and Updates Applications

Subject: General Tech | April 30, 2013 - 12:57 PM | Tim Verry
Tagged: wubi, Unity, ubuntu 13.04, ubuntu, openstack, linux, canonical

Canonical released its the Ubuntu 13.04 “Raring Ringtail” Linux distribution earlier this week. The updated operating system incorporates a new Linux kernel, newer pre-installed applications, and a tweaked Unity desktop environment. Enterprise and server users also have updated server software stacks to look forward to, including the latest juju and OpenStack (Grizzly) releases.

Ubuntu 13.04 continues in the direction of convergence set in motion by Canonical and its founder Mark Shuttleworth. It is the first step towards Ubuntu running on many types of devices (including mobile) as it includes an updated Unity interface. The 13.04 release still uses the X window system, but Canonical has made tweaks to Unity and is offering up an optional download of the new Mir display backend that users can install. Mir is the display server that Ubuntu will be switching to with its next LTS release and that will reportedly enable a cross-platform Ubuntu/Unity experience. The Unity tweaks include disabling Workspaces and the “show desktop” button on the desktop (though they can be re-enabled in settings). There have also been tweaks to Ubuntu’s Dash UI, including a typo-tolerant search function and new result sorting options. It will not be until the next release that users will really start to see Ubuntu’s plans of convergence come together (heh), but even with the small changes present in 13.04, the traditional desktop OS is making considerations for mobile devices.

While the visual changes are minimal on Ubuntu 13.04 compared to 12.10, the new release does update a lot of the underlying software.At least on the outside, Ubuntu 13.04 has not changed much from its 12.10 predecessor. Ubuntu 13.04 is based on the upstream 3.8.8 Linux kernel, and incorporates a number of updates to the pre-installed applications and core software. The updates include Unity 7, LibreOffice 4, and Python 3.3 (future versions of Ubuntu will remove Python 2 completely, though it will still be available as a downloadable package). Gwibber has also been replaced with a new service called “Friends” that takes all of your social networking accounts and combines them under your Ubuntu Online account.

Additionally, Ubuntu 13.04 also no longer includes the Wubi installer, which allowed users to install Ubuntu as a program within Windows and got around the need to mess with partitioning. Although there was a bit of overhead in doing the install this way, it was noticeably easier for new users than other methods. Canonical suggests that users interested in trying out the new operating system should simply use the live media, but installing it in a VM such as VirtualBox or VMWare may be more appropriate as some of the functionality is missing from the Live DVD environment in my experience (at least if you also want to try out functionality or other Linux software that would require a restart). Canonical has also cut the support time in half for Ubuntu 13.04 (and all future interim releases) from 18 months to 9 months. Hopefully the development team puts the reduced support workload to good use by investing the time in quick and stable releases.

So far, Ubuntu 13.04 has been getting positive reviews, though some users have run into issues running the operating system on their particular hardware (a bit of instability is expected with a new release, however).

If you are interested in Ubuntu 13.04 “Raring Ringtail,” you can read more about the changes in the official release notes and grab a download of the OS from the Ubuntu website or the updater if you are currently running Ubuntu 12.10.

New Linux Kernel 3.9 Adds New Features Including KVM on ARM and SSD Caching Support

Subject: General Tech | April 30, 2013 - 09:46 AM | Tim Verry
Tagged: ssd caching, operating system, linux, kernel 3.9, kernel, arm, 802.11ac

Linus Torvalds recently released a new version of the Linux kernel -- version 3.9 -- that advances the core of the GNU/Linux operating system with a number of new features. Among other tweaks, the new kernel rolls in new drivers, improves virtualization support, adds new hardware sleep modes, and tweaks file system and storage support.

The new kernel has added quite a few new experimental features, but developers/enthusiasts will no longer have to employ the CONFIG_EXPERIMENTAL flag when compiling the kernel in order to enable them. The kernel development team has decided to remove that option, enable the features by default, and merely tag those experimental features in the documentation. One of the experimental features is SSD caching that allows a solid state drive to cache both reads and writes. The SSD can cache frequently accessed data on the faster solid state drive as well as take the write cached data and write it to the hard drive when the IO subsystem isn’t being heavily utilized. The feature is not new to Linux distributions, but the caching support has now been moved to the kernel. Furthermore, the kernel is now RAID-aware when using the btrfs file system and RAID 5 or RAID 6.

On the driver front, Linux Kernel 3.9 now supports Intel’s upcoming 802.11ac Wi-Fi adapters, improved HD audio codec, AMD’s Oland (8500/8600) and Richland GPUs, and additional NVIDIA GPU support. The new kernel also rolls in a power-optimized driver for Intel’s Haswell GPU and several more track pads.

Kernel 3.9 also adds a new suspend/sleep mode. It will use more power than the traditional S3 (suspend to memory) sleep mode because components are not completely powered down (merely at their lowest sleep mode), but the system will be almost-instantly accessible upon exiting the new suspend mode as a result. According to H-Online, this "lightweight suspend" mode would be ideal for mobile devices or hardware used in network appliances. Also interesting is support for a KVM hypervisor on ARM Cortex A15 SoCs as well as some software tweaks to the kernel to improve web server workloads by allowing multiple networking sockets (and associated CPU processes) to listen on the same network port.

In all, version 3.9 looks to be a worthy upgrade, and one that I hope Linux distro makers will opt for in upcoming releases. I think the new drivers and the SSD caching being rolled into the kernel are the most important features for desktop users, though the networking stack improvements also sound interesting.

For more details, Thorsten Leemhuis has written up an extensive article on the new kernel.

Can you go too far with a gaming mouse? The Shogun Bros Ballista MK-1 Pro

Gaming mice continue to evolve as the market has become saturated, with companies striving to stand out in the crowd but Shogun Brothers may have taken this a bit far.  While having 8200 DPI and 12000 FPS is impressive, being able to set the X and Y sensitivity separately seems excessive.  The ability to save five different profiles for button programming is impressive but when the mouse is capable of displaying the name of that profile you have perhaps reached a new level altogether.  Perhaps the most telling is that the mouse is clearly labelled with a warning not to even attempt to use the mouse without reading the instructions first.  However, if this sounds like the mouse of your dreams, head to eTeknix to see this mouse in action.

"For the last couple of days I have been spending my evening gaming and putting the Ballista MK-1 gaming mouse from Shogun Bros through its paces. Until a few weeks ago I had never even heard of Shogun Bros and give that the gaming peripheral is somewhat dominated by a few big brands it can be hard for another name to squeeze through. Yet a quick look online has shown that products like the Ballista and other products from Shogun Bros have been getting a lot of attention and a lot of love from both review media and the gaming community, so what is all the fuss about?"
