What helium shortage? I have a bunch stored in my HGST drive

Subject: General Tech | March 26, 2015 - 12:32 PM |
Tagged: hgst, western digital, helium, hdd

The new generation of helium filled HDD from HGST take their longevity seriously, rating them at 2.5 million hours MTBF.  This generation also has 7 disks squeezed into the shell, with current capacities reaching 8TB and a shingled 10TB model currently being tested for release later this year.  The increased life and storage density are only part of the benefits that helium brings, 23% lower operating power and temperatures 4-5°C lower than traditional drives will also have an impact on data centre operating costs.  In their article The Register did ask how long the HelioSeal will keep the helium contained and while they did not get an exact figure, the 5 year warranty gives you a good idea of a lower limit.

Acer's Latest 15.6" Chromebook Powered By Core i5 (Broadwell-U) Processor

Subject: General Tech | March 26, 2015 - 01:34 AM |
Tagged: core i5, Chromebook, chrome os, broadwell-u, acer

Acer is adding an updated Chromebook to its education-focused C910 lineup. The new Acer C910-54M1 ups the hardware ante by incorporating a Broadwell-U based Intel Core i5 processor which will make this the fastest Chromebook on the market (for what that's worth). 

This new C910 remains aimed at schools and businesses with a sturdy frame, large (for a Chromebook) 15.6" (up to) 1080p display, and eight hours of battery life. Below the display sits an island style keyboard and a large trackpad. Except for the arrow keys, Acer was able to use "regular" sized keys and did not shrink the shift or backspace keys which can be annoying. A webcam and two large upward facing speakers are also present on the C910.

External I/O includes:

  • 1 x USB 3.0
  • 1 x USB 2.0
  • 1 x HDMI
  • 1 x SD card reader

The port selection is about what one would expect from a Chromebook, but the inclusion of USB 3.0 is welcome for accessing external storage.

Internally, the C910 Chromebook is powered by a dual core (four threads with Hyper-Threading) Broadwell-U Core i5 5200U processor clocked at 2.2GHz base and up to 2.7GHz Turbo Boost with a 15W TDP and 3MB cache. This particular processor includes Intel HD Graphics 5500 clocked at up to 900 MHz. Other hardware includes 4GB DDR3 memory and a 32GB SSD. Wireless hardware includes 802.11ac Wi-Fi and Bluetooth 4.0. 

Acer's new Chromebook is big and powerful, but will the increased hardware provide a noticeably better Chrome OS experience? Intel (naturally) seems to think so with its push to get Core i3 processors into Chromebooks last year. The Broadwell-U Core i5 should be just as fast (maybe even a bit faster with smoother UX and graphics) while sipping power. The alleged eight hours of battery life is impressive as well considering. The downside, because of course there always is one, is pricing. The C910-54M1 will be available in April with a 1080p display for $500. 

At that price point, it is squarely in budget Windows notebook territory as well as high end convertible (e.g. Bay Trail) tablet territory. It will be interesting to see how it ends up doing compared to the other options which each have their own trade offs.

Windows Apps Still Smell Like Windows RT

Subject: General Tech | March 25, 2015 - 06:23 PM |
Tagged: microsoft, windows, windows 10, winRT, windows rt

Even though I am really liking the Windows 10 operating system from a technical standpoint, I did not mind Windows 8.x, as software, either. My concern was its promotion of the Windows Store for the exact same reasons that I dislike the iOS App Store. Simply put, for your application to even exist, Microsoft (or Apple) needs to certify you as a developer, which they can revoke at any time, and they need to green light your creations.

windows-10.png

This has a few benefits, especially for Microsoft. First and foremost, it gives them a killswitch for malicious software and their developers. Second, it gives them as much control over the platform as they want. If devices start flowing away from x86 to other instruction sets, like we almost saw a few years ago, then Windows can pick up and go with much less friction than the corner they painted themselves into with Win32.

This also means that developers need to play ball, even for terms that Microsoft is forced to apply because of pressure for specific governments. LGBT groups should be particularly concerned as other platforms are already banning apps that are designed for their members. Others could be concerned about encryption and adult art, even in Western nations. If Microsoft, or someone with authority over them, doesn't want your content to exist: it's gone (unless it can run in a web browser).

On the plus side, I don't see the rule where third-party browser engines are banned anymore. When Windows 8 launched, all browsers needed to be little more than a reskin of Internet Explorer.

Beyond censorship, if Microsoft does not offer a side-loading mechanism for consumers, you also might need to give Microsoft a cut of your sales. You don't even seem to be able to give your app to specific people. If you want to propose to your significant other via a clever app, there does not seem to be a method to share it outside of the Windows Store unless you set up their device as a Window developer ahead of time.

Why do I say all this today? Because Microsoft has branded Universal Apps as Windows apps, and their strategy seems to be completely unchanged in these key areas. What kept me from updating to Windows 8 was not its user interface. It was the same thing that brought me to develop in Web technologies and volunteer for Mozilla.

It was the developer certification and lack of side-loading for modern apps.

I get it. Microsoft is tired of being bullied with crap about how it is insecure and a pain for the general public. At the very least, they need a way for users to opt out, though. What they are doing with Windows 10 is very nice, and I would like to see it as my main operating system, but I need to prioritize alternative platforms if this one is heading in a very dark direction.

Win32 might be a legacy API, but the ability to write what I want should not be.

About time you provided some in game footage, meet Blood Bowl 2

The teaser trailer for Blood Bowl 2 has been around for a while but was obviously not representative of what the game will look like in match.  Rock, Paper, SHOTGUN has posted a new video which does feature a look at the new interface for those who find the NFL nowhere near as violent as they like their football.  Cyanide is starting the game out with 8 races so it is possible that some of the more interesting balance issues caused by certain races in the first iteration will be ironed out, hopefully as they include new races they will be available for little or no money for those who purchased the initial release of this sequel.  If you enjoy inflicting turn-based tactical trauma then keep your eyes out for this release.

"We’ve had a little chat with the makers of Blood Bowl II [official site] – and isn’t it nice to chat with people! – and peered at a few screenshots and swish trailers. With spring approaching, and therefore the turn-based tactical bloodsport’s release, we’re at the point in its marketing campaign where we get to see more of the game itself."

Tagged: Android, security

If you are running a device with Android 4.3 or earlier you should avoid third-party app stores; arguably all users should but there are times when Google Play does not offer what you need.  A security problem with the way that APK files are authenticated during install can allow a seemingly harmless app to be modified, either at the source or while being transmitted, leading to the installation of an app that may not be entirely honest about what it does.  Palo Alto Network's testing shows versions 4.4+ do not suffer from this particular problem nor do the vetted apps at the Google Play store.  It is unlikely you will encounter this problem unless you usually install things from places like Creepy Ice Cream Van Discount Apps and Malware,  but you should be aware of the existence of this issue.  More at The Inquirer.

Pixar Renderman Is Free for Non-Commercial Use

Tagged: renderman, pixar, disney

Well that's a surprise. Pixar Renderman, the software used and developed by Pixar to turn computer-represented geometry into wonderful images, is now free for non-commercial use. This is not quite as free as Unreal Engine 4, which does not require royalties for rendered audio/video at all because the content is viewed without the engine, but free for non-commercial is still a big deal considering what Renderman is. While Pixar is known for their movies, they are very much software engineers.

Thumbs up all around.

Currently the rendering package integrates with Autodesk Maya and KATANA by The Foundry. Pixar has Cinema4D and Houdini listed as “in development”. They also claim to be interested in 3D Studio Max, because of course they are, as well as Modo, Rhino, Lightwave, and Blender.

Yay Blender!

The above list only considers dedicated plug-ins. Pixar Renderman can also be run as a standalone application that accepts their file format, “RIB”, from a command-line interface. There has been many of these for Blender and other 3D suites over the last basically forever. A plug-in is nicer for artists however, and it is good to see Pixar is not afraid of open-source suites to pair with their proprietary rendering package. Also, "Blenderman" is a hilarious name.

Getting heavy into HAMR's theory

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.

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.

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.

windows-10-secure-boot.png

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.

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."

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."

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.

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.""

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.

ie-wheeee-dead.jpg

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...

NVIDIA Announces DIGITS DevBox - 28 TFLOPS, 1300 Watts, $15k

Tagged: nvidia, DIGITS

At GTC, NVIDIA announced a new device called the DIGITS DevBox:

GTC-30.jpg
        

The DIGITS DevBox is a device that data scientists can purchase and install locally. Plugged into a single electrical outlet, this modified Corsair Air 540 case equipped with quad TITAN X (reviewed here) GPUs can crank out 28 TeraFLOPS of compute power. The installed CPU is a Haswell-E 5930K, and the system is rated to draw 1300W of power. NVIDIA is building these in-house as the expected volume is low, with these units likely going to universities and small compute research firms.

Why would you want such compute power?

GTC-29.jpg

DIGITS is a software package available from NVIDIA. Its purpose is to act as a tool for data scientists to manipulate deep learning environments (neural networks). This package, running on a DIGITS DevBox, will give much more compute power capability to scientists who need it for their work. Getting this tech in the hands of more scientists will accelerate this technology and lead to what NVIDIA hopes will be a ‘Big Bang’ in this emerging GPU-compute-heavy field.

Programmers will be able to use C, C++, Fortran, Java, and Python to write HSA-compliant code which is then compiled into HSAIL (Heterogeneous System Architecture Intermediate Language) and from there to the actual binary executables which will run on your devices.  HSA currently supports x86 and x64 and there are Linux kernel patches available for those who develop on that OS.  Intel and NVIDIA are not involved in this project at all, they have chosen their own solutions for mobile devices and while Intel certainly has pockets deep enough to experiment NVIDIA might not.  We shall soon see if Pascal and improvements Maxwell's performance and efficiency through future generations can compete with the benefits of HSA.

The current problem is of course hardware, Bald Eagle and Carrizo are scheduled to arrive on the market soon but currently they are not available.  Sea Islands GPUs and Kaveri have some HSA enhancements but with limited hardware to work with it will be hard to convince developers to focus on programming HSA optimized applications.  The release of the official specs today is a great first step; if you prefer an overview to reading through the official documents The Register has a good article right here.

"The HSA Foundation today officially published version 1.0 of its Heterogeneous System Architecture specification, which (if we were being flippant) describes how GPUs, DSPs and CPUs can share the same physical memory and pass pointers between each other. (A provisional 1.0 version went live in August 2014.)"
