It will take a bit of work with a soldering iron but Hack a Day has posted an article covering how to mod one of the GPUs on a GTX690 into thinking it is either a Quadro K5000 or Tesla K10.  More people will need to apply this mod and test it to confirm that the performance of the GPU actually does match or at least compare to the professional level graphics but the ID string is definitely changed to match one of those two much more expensive GPUs.  They also believe that a similar mod could be applied to the new TITAN graphics card as it is electronically similar to the GTX690.   Of course, if things go bad during the modification you could kill a $1000 card so do be careful.

"If hardware manufacturers want to keep their firmware crippling a secret, perhaps they shouldn’t mess with Linux users? We figure if you’re using Linux you’re quite a bit more likely than the average Windows user to crack something open and see what’s hidden inside. And so we get to the story of how [Gnif] figured out that the NVIDIA GTX690 can be hacked to perform like the Quadro K5000. The thing is, the latter costs nearly $800 more than the former!"

Tagged: oss, open source, networking, linux networking group, linux, linaro, arm

Linaro, a non-profit engineering group, announced a new collaborative organization called the Linux Networking Group at the Embedded Linux Conference in San Francisco this week. The new group will work on developing open source software to be used with ARM-based hardware in cloud, mobile, and networking industry sectors. Of course, being open source, the software for ARM SoCs will be used with Linux operating systems. One of the Linux Networking Group’s purposes is to develop a new “enhanced core Linux platform” for networking equipment, for example.

The new Linux Networking Group is currently comprised of the following organizations:

  • AppliedMicro
  • ARM
  • Enea
  • Freescale
  • LSI
  • MontaVista
  • Nokia Siemens Networks
  • Texas Instruments

The new cooperative has announced four main goals for 2013:

  1. "Virtualization support with considerations for real-time performance, I/O optimization, robustness and heterogeneous operating environments on multi-core SoCs.
  2. Real-time operations and the Linux kernel optimizations for the control and data plane.
  3. Packet processing optimizations that maximize performance and minimize latency in data flows through the network.
  4. Dealing with legacy software and mixed-endian issues prevalent in the networking space."

Reportedly, Linaro will have an initial software release within the first half of this year. Further, the organization will follow up with monthly software updates to improve performance and add new features. More collaboration and the furthering of ARM-compatible open source software is always a good thing. It remains to be seen how useful the Linux Networking Group will be in pushing its ARM software goals, but here’s hoping it works out for the best.

WINEing about the profitability of selling games for Linux

Tagged: carmack, linux, gaming, wine

John Carmack has been stirring the pot recently, from the questionable launch of the PC version of Rage, to poking at consoles remaining capped at 30fps to his disappointment in iD abandoning mobile game development.  More recently he has gone on record stating that there is little to no money to be made developing games for Linux.  His company has tried, Quake Arena and Quake Live both proved to be difficult to create and to have limited adoption as a test for the amount of possible sales.  This does not mean he has given up on Linux users completely, instead as he told The Inquirer he sees a different solution to the difficulties involved in designing games for Linux; improve WINE.  With a faster and more stable Windows (not an) Emulator for Linux iD and other companies wouldn't have to worry about parallel development, it would come closer to compile once and run anywhere.  Even better for game developers, there is already a dedicated group of programmers improving WINE so they would not lose man-hours better spent designing games.  You can also catch his comments about Steam appearing on Linux.

Fanless MintBox PC Receives Price Cut, Makes It More-Competitive Intel NUC Alternative

Subject: Systems | February 3, 2013 - 09:32 AM |
Tagged: mintbox, mint, linux, fitpc3, compulab

The MintBox is a small form factor, fanless computer released in summer 2012. It was developed in collaboration between CompuLab and the Linux Mint project. At launch, the base model retailed for $476, but CompuLab has cut the price by almost $100 to kick off 2013.

 

mintbox_front.png

The MintBox basic is powered by a dual core AMD G-T40N APU clocked at 1.0 GHz, 4GB of RAM, an APU-integrated Radeon G290 GPU, and 250GB hard drive. The system has a aluminum chassis that acts as a heatsink. It is essentially CompuLab’s fitPC3 case with a few custom tweaks to add the Linux Mint logo. Further, it comes pre-loaded with the Linux Mint 13 operating system. Wi-Fi and Bluetooth 3.0 radios are included as well as two mini-PCIe cards and one mSATA connector (for an SSD).

mintbox.png

The front of the MintBox has four USB 2.0 ports surrounding the Mint logo. The rear of the MintBox includes the following connectivity options:

  • 1 x HDMI
  • 1 x DisplayPort
  • 1 x S/PDIF
  • 2 x USB 3.0
  • 2 x USB 2.0
  • 2 x eSATA
  • 1 x RS232 serial port
  • 2 x external Wi-Fi antennas .

 

In many respects, the MintBox resembles a typical home wireless router, but it is actually a full PC. Before shipping and any applicatable taxes, the MintBox Basic is $379. Reportedly, 10% of the proceeds will go towards the Linux Mint project to assist with development of the open source operating system. While the hardware itself is not new, Mint and CompuLab are offering up a healthy discount which may bring it more in line with Intel’s NUC systems. It may not be as fast, but it will cost less and is pre-configured unlike the DIY NUC.

Have you been looking to get a small form factor system? What do you think about a fanless box running Linux Mint for your next PC?

Recent gains in gaming on Linux

Subject: General Tech | January 28, 2013 - 12:42 PM |
Tagged: linux, Ivy Bridge, ubuntu 13.04

Phoronix has released a pair of reviews focusing on the graphical performance changes we have seen recently when gaming on a Linux system.  The first looks at the last seven major kernel updates and how they changed the performance of Intel's HD4000 graphics core.  The news is not great, in most cases the performance remained mostly unchanged and there are a few instances where the performance gain seen by kernel 3.4 have disappeared by 3.8 and in some cases it would make sense to wait until Mesa 9.1 arrives. 

Their second article looks at the upcoming Ubuntu 13.04 release and the support the OS will have for AMD's GPUs straight out of the box with no customization.  From there they move onto Intel's HD3000 graphics with good results to report.  The new OS will not be out until April, but from what Phoronix has seen not only will this kernel handle discrete and integral GPUs well, the performance is the best they've seen yet.

"With the Intel Haswell product launch coming up soon, here's a look at how the Intel "Ivy Bridge" HD 4000 graphics support has matured on the seven most recent Linux kernel releases. This benchmarking shows how the performance of the Intel DRM driver has changed between the Linux 3.2 kernel and the Linux 3.8 kernel that's presently under development when using the integrated graphics found on the latest-generation Core i7 CPU."

CES 2013: Canonical Shows Off Ubuntu OS For Smartphones

Subject: Mobile | January 10, 2013 - 03:22 PM |

Ubuntu_Scopes.jpg

Earlier this month Canonical showed off a new version of its Ubuntu operating system intended for mobile phones. The Ubuntu for smartphones operating system is meant to extend the Ubuntu UI and UX to the smartphone screen. Canonical wants its OS to span from servers to phones and Ubuntu for phones is the latest step in that plan.

While there is no official hardware yet, the new operating system will be aimed at both low-end and high-end smartphones alike. It will support the standard array of smartphone functions–phone, sms, email, web browsing, and apps–along with the familiar Ubuntu user interface that is navigated by touch gestures. Ubuntu for phones will run on x86 and ARM hardware and is compatible with the Android Board Suppot Package. That means that users can actually run Ubuntu on many existing smartphones which are currently running Google's Android OS. Unlike Android, there is no Java VM, and the Ubuntu for phones operating system can run both HTML5 and native applications. At CES, Canonical demonstrated the OS using a Galaxy Nexus smartphone.

Ubuntu OS for Smartphones_launcher.jpg

Ubuntu smartphones will feature a familiar Unity-like user interface with a number of tweaks to make it easier to navigate using a touchscreen. The OS will use a feature called Edge Magic, which includes swipe gestures inwards from each side of the phone to open applications, read notifications, change settings, and return to the home screen. Users can also use voice and text commands to control the smartphone. For example, users can swipe left to open the application launcher, drag from the left side to the right side of the screen to display all currently running apps, and drag up from the bottom to open application-specific settings. Swiping from the right acts as the 'back' function while dragging down from teh top opens the notifications and device-wide settings. There are no hardware buttons with Ubuntu for smartphones, and Canonical founder Mark Shuttlework has stated that keeping UI elements hidden until needed was a priority with Ubuntu for phones.

Ubuntu OS for Smartphones_keyboard.jpg

Ubuntu for phones is aimed at a wide range of smartphone hardware. On the low end, Ubuntu needs at least a dual-core ARM Cortex A9, 1GB of RAM, and 4GB of internal storage. The budget smartphones will run native apps (ideally) faster than similar code on Android due to the apps being closer to the hardware. Multitouch will be supported but the destkop functionality when the phone is docked is not available. On the other hand, high end smartphones will be able to access a full Ubuntu desktop when the phone is docked along with a mouse and keyboard. 

Additional features of Ubuntu for smartphones include global search of applications, content, and products, Deep Content Immersion, and personalized artwork on the welcome (lock) screen. Further, Ubuntu One cloud storage, enterprise management tool compatibility, and regular updates are also rolled into the operating system. Ubuntu does include scopes which are similar in function and aesthetics to desktop Ubuntu. The scopes include a list of applications, contacts, videos, and music (among others).

The following chart lists the recommended/referrence specifications for budget and premium smartphones running the Ubuntu mobile OS.

  Entry Level High End
SoC dual core Cortex A9 quad core Cortex A9 or better
RAM 1GB preferred minimum of 1GB
Storage 4-8GB eMMC + SD card min 32GB eMMC + SD card
Display Resolution WVGA 800x400 720p or 1080p
Multi-Touch Yes Yes
Desktop No Yes
Convergence No Yes

Interestingly, users of the Galaxy Nexus smartphone will be able to test drive Ubuntu for smartphones later this year by flashing their device with the new OS. As far as retail hardware with Ubuntu pre-installed, Canonical is reportedly working on developing partnerships with handset makers. Canonical hopes to being shipping devices begining in Q4'13 or Q1'14.

From the various video demonstrations of the Ubuntu for smartphones operating system, it appears extremely slick and user friendly. Curiously, Canoncial was not willing to let CES attendees go hands-on with the reference phone, which may mean that the operating system is not quite ready for prime time. Despite that hesitation, I do think that Ubuntu for smartphones shows a lot of promise as a mobile, touchscreen-controlled operating system.

It is certainly a project that I will be following closely. With the untimely hardware failure of my Nokia N900, I am in need of a new power user-friendly smartphone. And an Ubuntu-powered mobile sounds like the perfect upgrade for me!

What do you think about Canonical's latest venture?

Tagged: ubuntu, solidrun, linux, desktop, cubox pro, cubox, computer

Israeli-startup SolidRun is launching an updated model of its CuBox mini PC called the CuBox Pro. The small desktop computer measures 2 x 2 x 2-inches and weighs a mere 91 grams. The CuBox Pro is not only small in size, it also sips a mere 3 watts at full load. It comes pre-loaded with Ubuntu Linux, but the CuBox Pro can be loaded with alternative operating systems by way of a microSD card. The hardware is nothing spectacular on the performance front, but it is capable of 1080p HD video playback. Interestingly, Youtube user rabeeh3000 reported that the CuBox Pro draws less than 2.5 Watts while playing a HD movie in XBMC.

Speaking of hardware, the CuBox Pro is powered by a Marvell ARMADA 510 SoC clocked at 800 MHz. It is supported by 2GB of DDR3 memory, and internal storage is handled by a microSD card slot.

Rear IO on the CuBox Pro includes two USB 2.0 ports, one HDMI video output, one eSATA connector, one Gigabit Ethernet port, DC power jack, and a single S/PDIF audio output on the side of the case. Further, the CuBox Pro has an infrared receiver, which will enable remotes to be used with media center software.

The CuBox Pro is slated to be available sometime in January for $159. Alternatively, the original CuBox with 1GB of DDR3 is available for $139. Admittedly, it is a bit pricey considering there are cheaper options like the Raspberry Pi but you are getting a complete OEM system (whereas you would have to add an SD card, USB infrared receiver, and case to the price of the Pi).

Valve Opens Steam for Linux Beta to General Public

Tagged: valve, ubuntu, steam, opengl, linux, gaming

Gamers were given an early holiday present last Friday when Valve announced it would be opening up its Steam for Linux beta to everyone. For the past few months the company has been testing out a version of its Steam client software intended to run on Ubuntu 12.04 Linux. Valve initially performed internal testing, and then proceeded to invite users to a closed beta. And now (finally), it seems that the company is comfortable enough with the applications stability that it can release it to the general public. While it is still very much beta software, it is actively being developed and improved.

Along with the move to a public beta, Valve is transitioning to GitHub to track changes and bug reports. Further, an apt repository is in the works, which should make installing and updating the Steam beta client easier, especially on non-Ubuntu distros (like Ubuntu forks). From the documentation available on the Steam website, it seems that apt-get install gdebi-coreand gdebi steam.debis still the preferred command line installation proceedure, however. 

Steam For Linux Beta.jpg

Further, Valve has fixed several issues in the latest Steam for Linux client. (Users that were in the closed beta will need to update). The company has improved the back navigation arrow placement and added discount timers and other UI tweaks to Big Picture Mode, for example. Valve has also fixed a bug concerning high CPU usage when playing Team Fortress 2 and an issue with the Steam overlay crashing while playing Cubemen.

Right now, the game selection is very limited, but the client itself is fairly stable. The traditional and Big Picture Mode UI are identical to the Windows version that many gamers are familiar with, which is good. Installation on Ubuntu was really easy, but I had trouble getting it to work with the latest version of Linux Mint. In the end, I was not able to use the CLI method, but the GUI instructions that Valve provides ended up working. At the moment Valve is only officially supporting the beta on Ubuntu, but it is likely to be expanded to other Debian forks as well as used in Valve’s Steam Box console.

The full announcement can be found on the Steam Community site, and the repository files are located here. Another useful resource is the getting started thread on the Steam forums, where you can find help getting the client installed (especially useful if you are trying to install it on an alternative distro).

Have you used the Steam for Linux client yet? I’m excited to see more games and engines support the Linux OS, as that will be what will make or break it.

Could Dell finally awaken the Penguin with Linux powered XPS machines?

Tagged: XPS 13, ultrabook, ubuntu 12.04, ubuntu, sputnik, linux, dell

Dell's XPS 13 Developer Edition is branded as an Ultrabook but it has two significant differences; a custom built Ubuntu distro and a price $250 higher than Dell's other Ultrabook offering.  Those two points are somewhat interrelated as Dell will be offering support equivalent to Windows powered machines which means new training, procedures and staffing which can be expensive to set up.  There is another reason the price is so high which is the hardware as, even the base model comes with a 256GB SSD; the rest of the hardware is pretty standard, an i7-3517U, 8GB DDR3 and no discrete video card.  It is hard to say if sticking the Developer Edition moniker on the machine will encourage people to purchase this ultrabook, if you are curious check out more at The Inquirer.

"TIN BOX FLOGGER Dell's decision to put arguably its best laptop on sale preloaded with Ubuntu Linux shows not only how far desktop Linux has come but how far Microsoft has fallen.

Dell announced its Project Sputnik earlier this year to a warm if not ecstatic reception. The firm had preloaded Linux onto its consumer machines before but they were hard to find and on forgettable machines. However with the XPS 13 the firm is not only loading Linux on its most high profile laptop but showing that Microsoft's operating system isn't the only choice in town for OEMs and consumers alike."
