Getting heavy into HAMR's theory

Subject: General Tech | March 24, 2015 - 12:43 PM |
Tagged: HAMR, science

If you are curious just how Heat Assisted Magnetic Recording is able to increase the storage densities of your HDDs then this post at Nanotechweb and the linked article will make a great read.  They deal with how plasmonic near-field transducers, which will oscillate in time with the frequency of a light source, as long as the light source's frequency is equal to or less than the plasma frequency.  This causes heat but nowhere near as much as if the light was used directly and so avoids potentially damaging hotspots.  They also delve into the materials which are being tested to provide more efficient heat transmission; it is not light reading but it is very informative for those curious about HAMR's development and future.

"Heat-assisted magnetic recording (HAMR) is a leading technology for advancing hard-disk-drive areal density beyond 1 Tb/in2. To reduce the magnetic coercivity, near-field transducers (NFTs) made of plasmonic nanostructures are used."

Seasonic Snow Silent; if you prefer your PSU meek and pale

Subject: Cases and Cooling | March 23, 2015 - 02:30 PM |
Tagged: seasonic, snow series, modular psu, 1050W, 80 Plus Platinum

The ability to deliver stable power is the primary attribute we look for in a PSU but the aesthetics should not be ignored, especially for modders and those with glass cases.  The Seasonic Snow Silent Series 1050W PSU is aptly named for its white finish which gives it a unique look in a very crowed market but the exterior does not tell the whole story.  With a total of eight 6+2 PCIe plugs and a 12V rail capable of providing 1044W @ 87 amps this PSU will certainly handle Crossfire or SLI and it will do so fairly quietly.  TechPowerUp liked the 7 year warranty as well as the performance and look of this PSU, especially considering it is priced roughly the same as the bog standard grey model which does not have the improved fan of this model.

PSU_top1a.jpg

"Seasonic released a special version of their Platinum offering with 1050 W capacity; it comes with a while paint job and is equipped with an FDB fan and a relaxed fan profile for less noise output, which will thrill users looking for a quiet high-performance PSU."

Subject: Memory | March 23, 2015 - 02:08 PM |
Tagged: overclocking, Dominator Platinum Series, ddr4-3400, ddr4, corsair

Speaking of components at the $999 price point, Corsair has just released a RAM kit aimed at the serious overclocker.  The Dominator Platinum Series 16GB DDR4-3400MHz kit now holds the record for fastest overclock at an impressive 4365.6MHz achieved on the Gigabyte X99-SOC board; you will be seeing more of both the motherboard and these DIMMs on this page in the near future. 

If you are looking for RAM that operates well using LN2 and serious overclocking these Corsair DIMMs are currently the best in class on the market.

DOM_DDR4-CUTAWAY-FEAT-ORANGE.jpg

Platinum Series DDR4 3400MHz 16GB memory kits which debuted at CES in January. The new kits are performance tuned to run air-cooled at an incredible 3400MHz and beyond on the Gigabyte X99-SOC Champion motherboard. The memory and motherboard duo together create one of the highest performance enthusiast PC platforms currently available.

Dominator Platinum Series 16GB (4 x 4GB) 3400MHz DDR4 Memory
The fastest DDR4 memory available from Corsair, the Dominator Platinum 3400MHz 16GB (4x4GB, 16-18-18-36) memory kits have a striking industrial with an orange anodized heat spreader that matches the color scheme on Gigabyte SOC motherboards. Like all Dominator Platinum memory modules, the new kits have patented DHX technology for cooler operation, user-swappable colored “light pipes” for customizable downwash lighting, and Corsair Link compatibility for real-time temperature monitoring. Dominator Platinum memory is built with hand-screened ICs, undergoes rigorous performance testing, and incorporates state-of-the-art cooling for reliable performance in demanding environments.

“Each Dominator Platinum 3400MHz DDR4 memory module is built with hand-picked ICs and tuned timing parameters to achieve blistering performance on Gigabyte’s X99-SOC Champion extreme overclocking motherboard,” said Thi La, Chief Operating Officer at Corsair. “Achieving insanely fast memory clock speeds is just the beginning. We can’t wait to see the incredible high-performance machines that PC enthusiasts create with them.”

“Our Gigabyte X99-SOC Champion is engineered with highly optimized trace paths between the processor and DIMM sockets to enable incredible memory clock speeds,” said Colin Brix, Director of Marketing of Gigabyte’s Motherboard Business Unit. “We worked with Corsair to tune an exceptional edition of Dominator Platinum DDR4 that can help overclockers push the X99-SOC Champion to reach unprecedented memory speeds.”

World Record for Fastest DDR4 Memory Frequency
On March 20, professional overclocker Hicookie set the world record for fastest DDR4 memory frequency using the Corsair Dominator 3400MHz DDR4 memory and Gigabyte X99-SOC Champion motherboard. Using liquid nitrogen, Hicookie established a record-breaking speed of 4365.6MHz.

Looking for an Android emulator?

Tagged: DuOS, Android

Be it for development reasons or a serious addiction to a certain game, there are those who find themselves wanting to run Android on a device larger than a phone or tablet.  For a mere $10 you can pick up DuOS, a supported Android emulator which will run on a PC, or at least a modern Intel powered machine as the emulator uses VT-x to run properly which is a shame for AMD users.  It will not run on ARM hardware but it is ARM v-7 compliant so you can use applications designed for the chip that most mobile hardware runs on with DuOS.  The footprint on your machine is tiny, 16GB maximum and you can root the installation very quickly if you are looking to test your modifications to the Android OS before installing them on your phone.  Techgage does mention that there is no help menu and you will need to update the application manually so plan to spend some time on the DuOS forums if you will be making use of this software.

"With so many devices out there, on many different operating systems, deciding which one you should purchase can be difficult. DuOS helps lessen that burden by providing an Android tablet experience on your Windows computer. Does DuOS step beyond the barriers that currently divide these OS’s, or are we still locked into one OS per device?"

NVIDIA Quadro M6000 Announced

Subject: Graphics Cards | March 23, 2015 - 07:30 AM |
Tagged: quadro, nvidia, m6000, gm200

Alongside the Titan X, NVIDIA has announced the Quadro M6000. In terms of hardware, they are basically the same component: 12 GB of GDDR5 on a 384-bit memory bus, 3072 CUDA cores, and a reduction in double precision performance to 1/32nd of its single precision. The memory, but not the cache, is capable of ECC (error-correction) for enterprises who do not want a stray photon to mess up their computation. That might be the only hardware difference between it and the Titan X.

nvidia-quadro-m6000.jpg

Compared to other Quadro cards, it loses some double precision performance as mentioned earlier, but it will be an upgrade in single precision (FP32). The add-in board connects to the power supply with just a single eight-pin plug. Technically, with its 250W TDP, it is slightly over the rating for one eight-pin PCIe connector, but NVIDIA told Anandtech that they're confident that it won't matter for the card's intended systems.

That is probably true, but I wouldn't put it past someone to do something spiteful given recent events.

The lack of double precision performance (IEEE 754 FP64) could be disappointing for some. While NVIDIA would definitely know their own market better than I do, I was under the impression that a common workstation system for GPU compute was a Quadro driving a few Teslas (such as two of these). It would seem weird for a company to have such a high-end GPU be paired with Teslas that have such a significant difference in FP64 compute. I wonder what this means for the Tesla line, and whether we will see a variant of Maxwell with a large boost in 64-bit performance, or if that line will be in an awkward place until Pascal.

Or maybe not? Maybe NVIDIA is planning to launch products based on an unannounced, FP64-focused architecture? The aim could be to let the Quadro deal with the heavy FP32 calculations, while the customer could opt to load co-processors according to their double precision needs? It's an interesting thought as I sit here at my computer musing to myself, but then I immediately wonder why did they not announce it at GTC if that is the case? If that is the case, and honestly I doubt it because I'm just typing unfiltered thoughts here, you would think they would kind-of need to be sold together. Or maybe not. I don't know.

Pricing and availability is not currently known, except that it is “soon”.

Microsoft Changes Secure Boot Rules with Windows 10, Could Mean OS Lockout

Subject: General Tech | March 22, 2015 - 09:14 PM |
Tagged: windows 10, Secure Boot, microsoft, linux

Secure Boot is a security measure that prevents malware from interfering with the boot process, but it can also prevent unsigned operating systems from booting on the same hardware. While Microsoft’s “Designed for Windows 8” guidelines required manufacturers to permit users to disable the Secure Boot option, the upcoming Windows 10 release will not have this rule in effect. At WinHEC it has been revealed that Windows 10 guidelines leave it up to the OEM to decide if they will allow users to disable UEFI Secure Boot in the system setup, and making this optional presents an interesting question about compatibility with other operating systems. OEM's will be required to ship computers with Secure Boot enabled to comply with “Designed for…” rules, and while they could then choose to provide the option to disable it (currently the required standard), preventing user installation of other OS software could be seen as a way to streamline support by eliminating variables.

Why does this matter if most people who purchase a Windows 10 computer will run Windows 10 on it? This could be an issue for someone who wished to either replace that Windows 10 installation with another OS, or simply dual-boot with an OS that didn’t support the Secure Boot feature (which could be a build of Linux or even an older version of Windows). Requiring OS files to contain digital signatures effectively locks out other operating systems without special workarounds or keys, and although open-source operating systems represent a small segment of the market thanks to the way computer hardware is sold to most people, it is concerning to think future hardware could cause a loss of the freedom of choice we have always had with operating systems.

Microsoft enjoys market dominance with Windows thanks to its licensing model (giving it a monopoly on pre-built PC systems that don’t have an Apple or Chrome logo on them), but reportedly began considering possibilities "to assert its intellectual property against Linux or any other open-source software” a decade ago, and this has reached farther than they probably imagined with the adoption of Android (from which Microsoft makes money on every device sold). Is this Secure Boot move nefarious, and does Microsoft consider Linux to be a potential threat to the their desktop market share? It could be that Microsoft would simply like to claim that Windows 10 is the safest version of Windows yet, and that isn’t a bad thing for consumers. Unless they want to easily use another OS on the hardware they purchased, that is.

SEC Filing Reveals NVIDIA Now Using Samsung for Some Manufacturing

Subject: General Tech | March 21, 2015 - 12:09 AM |
Tagged: TSMC, SoC, Semiconductor, Samsung, process node, nvidia, gpu, fab

Want to liven up your weekend? Forget college basketball, we all know that few things are more exciting than SEC filings - and oh boy do we have a great read for you! (OK, this one is actually interesting!)

10K.png

Ah, legal documents...

NVIDIA has disclosed in their latest 10-K filing that none other than Samsung is manufacturing some of the company’s chips. TSMC has been the source of GPUs for both AMD and NVIDIA for some time, but this filing (the full document is available from the SEC website) has a very interesting mention of the suppliers of their silicon under the “Manufacturing” section:

"We utilize industry-leading suppliers, such as Taiwan Semiconductor Manufacturing Company Limited and Samsung Electronics Co. Ltd, to produce our semiconductor wafers."

Back in December NVIDIA commented on its lawsuit against Samsung for alleged IP theft, which only makes this partnership seem more unlikely. However even Apple (which has their own famous legal history with Samsung, of course) has relied on Samsung for some of the production of their A-series SoCs, including the current crop of A8 chips.  Business is business, and Samsung Foundry has been a reliable source of silicon for multiple manufacturers - particularly during times when TSMC has struggled to meet demand at smaller process nodes.

Process_Tech.png

Samsung's Current Semiconductor Offering

It is unclear at this point whether the wafers produced by Samsung Semiconductor are for NVIDIA’s mobile parts exclusively, or if any of the desktop GPUs were produced there rather than at TSMC. The partnership could also be attributed simply to scale, just as Apple has augmented A8 SoC supply with their rival’s fab while primarily relying on TSMC. It will be interesting to see just how pervasive the chips produced by Samsung are within the NVIDIA lineup, and what future products might be manufactured with their newest 14nm FinFET process technology.

Cougar Launches QBX Mini ITX Case

Subject: Cases and Cooling | March 20, 2015 - 06:47 PM |
Tagged: water cooling, mini ITX, Cougar, air cooling

Cougar recently launched the QBX mini ITX case. The small form factor chassis is aimed squarely at gamers and enthusiasts looking for a high performance PC in a tiny box. 

The QBX is a completely black angular case measuring 7” x 10.2” x 14.5” packed with filtered vents. Front I/O is fairly standard including two USB 3.0 and two audio jacks. The case supports both air and water cooling while holding a ton of hardware. Specifically, the QBX is built to host Mini ITX motherboards, standard size (140mm) ATX power supplies, dedicated graphics cards (350mm), and CPU coolers up to 105mm tall. As far as storage, the QBX can hold a single 3.5” hard drive and four 2.5” solid state drives as well as a single vertically mounted slim optical drive.

Cougar QBX Mini ITX Computer Case.jpg

The case comes pre-installed with a single 90mm rear fan, and users can install up to six additional fans on the front, top, and side panels. The front and bottom vents have removable dust filters. A 120mm or 240mm radiator can be installed on the left side panel, but at most you can install one 120mm fan to cool the radiator.

Cougar QBX Mini ITX Case Interior.jpg

Cougar has engineered the case such that the power supply draws in cool air from the right side panel and exhausts it out of the top of the case to prevent adding extra heat to the system (it will be difficult enough to cool high end components in such a small case). Further, removing the left side panel reveals a hinged bracket that holds a fan (or the water cooling radiator) as well as the 3.5” drive bay and two 2.5” bays. Note that with a 240mm radiator installed, you will only be able to access a single 2.5” bay. This is a neat design but installing the CPU block of a closed loop water cooler is going to be a challenge depending on the length of the tubing.

There is some space behind the motherboard try to hide cables but you will likely need to do some custom cabling to not have it ultimately look like a rats nest considering how small this case is and how little area you have to work with, especially if you do end up installing all seven fans and five disk drives!

The Cougar QBX has an MSRP of $60 and will be available soon. More information can be found on this product page. Hopefully we can get one in for review to see how it stacks up to the Ncase M1 and Lian Li PC-Q33 Mini ITX cases.

When is an SoC not an SoC? When it is the GIGABYTE X99-SOC Champion

Subject: Motherboards | March 20, 2015 - 06:31 PM |
Tagged: gigabyte, x99-soc champion, Intel, X99

Relatively new to the market is the $360ish Gigabyte X-99-SOC Champion, expensive compared to previous Intel boards but a decent price for an X99 board.  It has four PCIe 16x slots of which two can only run at 8x maximum as well as three PCIe 1x slots, a single M.2 and a single SEx connector as well as a half dozen SATA 6Gbps ports which can run in RAID and another 4 which are only able to run in AHCI mode.  There are no C-type connectors but there are a plethora of USB 3.0 and 2.0 ports as well as a Thunderbolt header.  This is definitely a board for power users and manual overclockers as you can see in Hardware Canucks review here

You can also expect to see Morry's review of this Gigabyte board in the very near future.

Manufacturer: SilverStone

Introduction and First Impressions

The Fortress FT05 is the fifth iteration of SilverStone's Fortress series of enclosures, and, like the latest Raven case, this leverages the complete removal of 5.25" bays to reduce its overall size. We've seen this before as the FT03 completely removed optical support, but this enclosure is related far more closely to the current Raven enclosure than any of its predecessors.

FT05_Angle_Front.jpg

Introduction: The Heart of a Raven

If you're familiar with SilverStone's product lineup you'll know about the Fortress and Raven enclosures which both currently feature an unusual 90° motherboard orientation. This layout places I/O on the top of the case, and helps expel warm air straight up. The Fortress was originally a more conventional design with a standard motherboard layout, but SilverStone switched this to mirror the Raven series with the second version, the FT02. However, just as the Raven series diverged from the original design language and layout of the RV01 with later versions, the Fortress series has undergone some radical changes since its introduction. With this fifth version of the Fortress SilverStone has converged the two enclosure lines, and the FT05 is essentially a more businesslike version of the Raven RV05 - though the design's more conventional exterior also contains noise-dampening material which helps to further differentiate the two enclosures.

Much as the current Raven owes much of its design to an earlier version, in that case the RV01, this new Fortress is a return to the design of the FT02. That earlier Fortress was a large (and quite expensive) case that combined great expandability with excellent cooling, taking the RV01's 90° layout and opening up the interior for an expansive, easy-to-manage interior. A considerable amount of the second gen's interior was devoted to storage, and the front of the case was dominated by 5.25" drive bays.

Once pirated, always pirated? Microsoft muddles the Win10 upgrade news

Subject: General Tech | March 20, 2015 - 12:18 PM |
Tagged: windows 10, microsoft, confusion

Slashdot has linked to news out of Microsoft that the option to upgrade your non-genuine version of Win7, 8 or 8.1 to Windows 10 is not as clear cut as it sounded earlier in the week.  Microsoft stated in the interview that "they will remain in a “non-genuine” status and Microsoft will not support them".   This is more than a little odd if the stated purpose of this move, to reduce piracy rates across Asia, is correct as there is little to no reason to upgrade if your PC still remains unsupported.  Perhaps there is some sort of disconnect at Microsoft in which they think that one look at their new OS and Store will cause an epiphany in lifelong software pirates and they will leap at the opportunity to pay for Windows 10?

As Microsoft declined to elucidate further we really have no idea what they mean when they state that your Windows will remain unlicensed.  Will you simply have the same Reduced Functional mode, the black desktop overwrite that appears on non-genuine Windows currently?  Will you get all, some or none of the security updates?  Will it simply refuse to boot after a certain amount of time?  All in all it seems that Microsoft could have just skipped their original announcement as nothing seems to have changed.

This_Copy_of_Windows_is_not_Genuine.png

"When Microsoft confirmed it will offer free Windows 10 upgrades to pirates worldwide, many were shocked. VentureBeat has been trying to get more details from the company, which disclosed today that after PCs with pirated copies of Windows 7 and Windows 8.1 are upgraded to Windows 10, they will remain in a 'non-genuine' status and Microsoft will not support them."

You have read Ryan's review of the $999 behemoth from NVIDIA and now you can take the opportunity to see what other reviewers think of the card.  [H]ard|OCP tested it against the GTX 980 which shares the same cooler and is every bit as long as the TITAN X.  Along the way they found a use for the 12GB of VRAM as both Watch_Dogs and Far Cry 4 used over 7GB of memory when tested at 4k resolution though the frame rates were not really playable, you will need at least two TITAN X's to pull that off.  They will be revisiting this card in the future, providing more tests for a card with incredible performance and an even more incredible price.

Dammit Gabe, what did we do to you to deserve this?

Subject: General Tech | March 19, 2015 - 01:50 PM |
Tagged: sad, half life 3, gaben

Gabe, once again, will not confirm or deny the possibility of another Half Life game but did imply in an interview that there are no teams currently working on one.  The reason is sad but obvious, as our sometimes maligned Raptr posts have shown, DOTA 2 and CS:GO make up over 10% of the time spent gaming by those with Raptr installed and at the time this article was written 14% of online Steam users are playing those games.  That translates to a lot of hats being sold and a lot of money coming into Valve; significantly more than would come from a new Half Life thanks to the ongoing nature of those online games and the market they have created.

You can catch the interview from the links on Slashdot but stating that this is the end of single player focused games from Valve is an overstatement.  The online gaming market is more lucrative but there is still a market for those of us who prefer stories to online bragging rights and some of the work they have done on current game engines should be translatable to a financially viable single player game or ten.

"Half-Life 3 is undoubtedly one of the most anticipated games in history. While Valve transitioned from the revolutionary series that brought the company most of its original success, to online games like Team Fortress, Dota and Left 4 Dead, people still desperately want to believe that there is more coming for Half-Life."

What is FreeSync?

FreeSync: What began as merely a term for AMD’s plans to counter NVIDIA’s launch of G-Sync (and mocking play on NVIDIA’s trade name) has finally come to fruition, keeping the name - and the attitude. As we have discussed, AMD’s Mantle API was crucial to pushing the industry in the correct and necessary direction for lower level APIs, though NVIDIA’s G-Sync deserves the same credit for recognizing and imparting the necessity of a move to a variable refresh display technology. Variable refresh displays can fundamentally change the way that PC gaming looks and feels when they are built correctly and implemented with care, and we have seen that time and time again with many different G-Sync enabled monitors at our offices. It might finally be time to make the same claims about FreeSync.

But what exactly is FreeSync? AMD has been discussing it since CES in early 2014, claiming that they would bypass the idea of a custom module that needs to be used by a monitor to support VRR, and instead go the route of open standards using a modification to DisplayPort 1.2a from VESA. FreeSync is based on AdaptiveSync, an optional portion of the DP standard that enables a variable refresh rate courtesy of expanding the vBlank timings of a display, and it also provides a way to updating EDID (display ID information) to facilitate communication of these settings to the graphics card. FreeSync itself is simply the AMD brand for this implementation, combining the monitors with correctly implemented drivers and GPUs that support the variable refresh technology.

disp4.jpg

A set of three new FreeSync monitors from Acer, LG and BenQ.

Fundamentally, FreeSync works in a very similar fashion to G-Sync, utilizing the idea of the vBlank timings of a monitor to change how and when it updates the screen. The vBlank signal is what tells the monitor to begin drawing the next frame, representing the end of the current data set and marking the beginning of a new one. By varying the length of time this vBlank signal is set to, you can force the monitor to wait any amount of time necessary, allowing the GPU to end the vBlank instance exactly when a new frame is done drawing. The result is a variable refresh rate monitor, one that is in tune with the GPU render rate, rather than opposed to it. Why is that important? I wrote in great detail about this previously, and it still applies in this case:

The idea of G-Sync (and FreeSync) is pretty easy to understand, though the implementation method can get a bit more hairy. G-Sync (and FreeSync) introduces a variable refresh rate to a monitor, allowing the display to refresh at wide range of rates rather than at fixed intervals. More importantly, rather than the monitor dictating what rate this refresh occurs at to the PC, the graphics now tells the monitor when to refresh in a properly configured G-Sync (and FreeSync) setup. This allows a monitor to match the refresh rate of the screen to the draw rate of the game being played (frames per second) and that simple change drastically improves the gaming experience for several reasons.

slides01.jpg

Gamers today are likely to be very familiar with V-Sync, short for vertical sync, which is an option in your graphics card’s control panel and in your game options menu. When enabled, it forces the monitor to draw a new image on the screen at a fixed interval. In theory, this would work well and the image is presented to the gamer without artifacts. The problem is that games that are played and rendered in real time rarely fall into a very specific frame rate. With only a couple of exceptions, games frame rates will fluctuate based on the activity happening on the screen: a rush of enemies, a changed camera angle, an explosion or falling building. Instantaneous frame rates can vary drastically, from 30, to 60, to 90, and force the image to be displayed only at set fractions of the monitor's refresh rate, which causes problems.

Windows 10 Build 10041 Released to Insiders

Subject: General Tech | March 18, 2015 - 05:35 PM |
Tagged: windows 10, microsoft, build 10041

It has been a long time coming, but the new preview build of Windows 10 has been released. 10041 can be installed for users on the “Fast” ring, leaving users who opt into “Slow” to be on 9926 for a bit longer. You know, the wise enthusiast learns from their mistakes, but the smart enthusiast learns from the mistakes of others. At any rate, pun intended, a few things have changed in this build, but I expect that most of it is under the hood.

windows-10.png

On the user-facing side though, the Start menu has been modified to include transparency and Virtual Desktops can now support dragging windows between instances (or onto the + to create a new Virtual Desktop with that window in it). Each update, I have attempted to use Virtual Desktops but I have never stuck with it. Rather than being organized, it felt separated, which gave the impression that I was wasting more time context-switching than if I just sifted through cluttered windows. As always, I will give it another chance with 10041. Perhaps I am just using it wrong. We'll see.

There are some known bugs in this version, like always, so read up on it before making the update if your machine is important. I mean, even 9926 has some noticeable problems that are getting annoying, so you might even be net-positive, but look before you leap. That is, unless you are on an unimportant device or are amused by bugs and you want the newest nowest yesterday.

Speaking of which, as previously discussed, Microsoft intends to speed up the rate of “Fast” builds. Their users seem to want less-stable and more cutting edge builds, so they are hoping to have one or two builds per month.

Also, don't let my posts discourage anyone from trying Windows 10. Just because I need to report on all the issues that I experience (even some that ended up being coincidentally exploded hardware, whoops...) doesn't mean that I am casting shame on it. Ultimately, whatever you install Windows on is a device. If that device performs a critical function in your life, then you need to be aware of the issues that I know about. If not, then enjoy the pre-release experience.

I will probably be installing 10041 soon, especially if it brings new Intel and NVIDIA GPU drivers.

Update (March 19th @ 4PM EDT): I installed 10041 last night, and was greeted with two new graphics drivers: one for Intel and another for NVIDIA. Still to early to tell whether it fixed issues or made things worse, but nothing bad happened yet. I am hearing that some people are having difficulty installing audio drivers, though. Allyn linked me to a problem with Xonar cards, and people in the comments of this article mention "audio drivers" in general. About that, all I can say is that my Blue Yeti works fine, as both a mic and sound card.

Legacy of the Void closed beta kicks off at the end of the month

Get your twitch reflexes back to their peak over the next few weeks as the multiplayer beta for the third instalment of StarCraft 2 kicks off on the 31st.  On that date you will find out if you are invited to participate in the test and get to see the new units as well as the tweaks that have been applied to existing units.  The main page suggests that this episode will focus more on online multiplayer harassment tactics than all out assaults and so units have been altered to reflect that focus.  Blizzard also suggests this beta will go for longer than previous ones have so it will still be a while before we see the next chapter in the single player story.  You can catch the preview movie at Rock, Paper, SHOTGUN.

"Good news if you’ve been waiting to see how Big Stubbly Man and Chitin Stilettos Woman managed to defeat timeless evil once and for all until the next sequel: the third and final chunk of StarCraft II is very much on its way. In fact, beta invites for the Protoss-focused Legacy of the Void are due to go out before the end of the month. “Much has changed” since the last time Blizzard let us have a peek at their void."

Get your pirated Windows a letter of marque

If you know a friend that has a friend that might have picked up a copy of Windows from a site of ill repute they still have a chance to redeem their soul.  At WinHEC today Microsoft announced that any eligible version of Windows running on hardware compatible with Windows 10 can also upgrade to a new and fully licensed version of Windows 10 when it is released.  This is an interesting move by Microsoft but there is sense behind the move as it will increase their customer base for purchasing apps from the Microsoft Store and any licensing which may come into effect after the free year they offer.  It also gives them more accurate data on the number of users of Windows and possibly other metadata as well.

"Microsoft will make Windows 10 available as a free upgrade even to pirated copies of other Windows operating systems in China. Terry Myerson of Microsoft's operating systems unit made the announcement at the WinHEC technology conference in Shenzhen, China, and then told Reuters, "We are upgrading all qualified PCs, genuine and non-genuine, to Windows 10.""

d'IE!

First of all, this is possibly the shortest title we have ever made at PC Perspective. I guess I win something? Either way, WinBeta claims that Microsoft has finally said, on the record, that the Internet Explorer branding will not be applied to Project Spartan. The quote is from Chris Capossela, Executive Vice President and Chief Marketing Officer at Microsoft.

And Web Developers say...?

We’re now researching what the new brand, or the new name, for our browser should be in Windows 10," said Capossela. "We’ll continue to have Internet Explorer, but we’ll also have a new browser called Project Spartan, which is codenamed Project Spartan. We have to name the thing.

This quote still seems a little vague for me. While it clearly separates “the new brand” from “Internet Explorer”, it does not definitively say that Project Spartan will not be derived from it (pardon the double-negative). Of course, I think it is safe to say that it will be a wholly new brand, but I don't think this quote changes anything.

By the way, may I recommend “PhoIEnix”? I'm pretty sure no-one tried that name for a web browser before being immediately disputed by Phoenix Technologies. Wow, that's oddly specific to not be a reference to anything, at all, ever...
