The Intel Open Source Technology Group along with CircuitCo recently launched a new small form factor bare-bones system based on open source hardware and running open source software. The Minnowboard includes a 4.2” x 4.2” motherboard, passively-cooled processor, rich IO, UEFI BIOS, and the Angstrom Linux operating system.
The Minnowboard is powered by a single core Intel Atom E640 processor clocked at 1GHz. It is a 32-bit CPU with HyperThreading and VT-x virtualization support. Other hardware includes an integrated Intel GMA 600 GPU, 1GB of DDR2 memory, and 4MB of flash memory used for motherboard firmware. Storage can be added by plugging a SSD or HDD into the single SATA II 3Gbps port.
The Minnowboard has following IO options:
- 1 x micro SD
- 1 x SATA II 3Gbps
- 2 x USB 2.0 ports
- 1 x micro USB
- 1 x mini USB (serial connection)
- 1 x RJ45 jack (Gigabit Ethernet)
- 2 x 3.5mm audio jacks (line in and line out)
- 1 x HDMI
The Minnowboard also has a GPIO header with 8 buffered GPIO pins, 2 GPIO LEDs, and 4 GPIO switches. As such, the system can be expanded by adding extra open source modules called “Lures.” The board is aimed at developers and embedded system manufacturers. The Minnowboard can be used as the bare system or can be integrated into a case or larger device.
The Minnowboard costs $199 and is available for purchase now from Digi-Key, Farnell (UK), Mouser, and Newark.
Obviously, the Minnowboard is nowhere near as cheap as the $35 Raspberry Pi, but it is running x86 hardware which may make it worth it to some users.
If you are interested, you can learn more about the hardware and get involved with the Minnowboard project over at Minnowboard.org.

Throughout last year, AMD worked with the Open Compute Foundation to develop open source hardware for servers. The goal of the project was to bring lower-cost, efficient motherboards (compatible with AMD processors) to the server market. Even better, the AMD-compatible hardware is open source which gives companies and OEM/system integrators free reign to modify and build the hardware themselves. The latest iteration of the project is called Open 3.0 and motherboards based on the design(s) are available now from a number of AMD partners.
An AMD Open 3.0 motherboard.
According to a recent AMD press release, Open 3.0 motherboards will be available from AVnet.inc, Hyve, Penguin Computing, and Zt Systems beginning this week. The new motherboards strip out unnecessary and "over-provisioned" hardware to cut down on upfront hardware costs and electrical usage. Open 3.0 uses a base open source motherboard design that can then be further customized to work with a variety of workloads and in various rack/server configurations. Servers based on OPen 3.0 will range from 1U to 3U in size and can slot into standard 19" racks or Open Rack environments. The boards with their dual Opteron 6300-series processors will reportedly be suitable for High Performance Computing (HPC), Virtual Desktop Infrastructure (VDI), Cloud applications, and storage servers. AMD claims that its Open 3.0 motherboards can reduce the Total Cost of Ownership (TCO) of servers by up to 57% in data centers. AMD claims that a server based on Open 3.0 has a TCO of $4,589 while one based on a traditional OEM motherboard costs up to 57% more at $10,669. The AMD-provided example sound nice. Despite the example likely being the best-case-scenario, the idea behind the Open Compute Project and the AMD-specific Open 3.0 hardware does make sense. Customers should see more competition with motherboards that are cheaper to produce and run thanks to the open source nature. Further details on the status of Open 3.0 and the available hardware is being discussed at an invitation-only industry round-table this week between partners, interested enterprise customers, and a number of companies (including AMD, Broadcom, and Quanta).
For the uninitiated, the Open 3.0 hardware features a motherboard that measures 16" x 16.7" and is intended for 1U, 1.5U, 2U, and 3U servers. Each Open 3.0 board includes two AMD Opteron 6300 series processors, 24 DDR3 DIMM slots (12 per CPU, 4 channels with 3 DIMMs each), six SATA ports, 1 managed dual-channel Gigabit Ethernet NIC, up to four PCI-E slots, and a single Mezzanine connector for custom modules (eg. the Mellanox IO or Broadcom Management card). Board IO will include a single serial port and two USB ports.
I'm glad to see AMD's side of the Open Compute Project come to fruition with the company's Open 3.0 hardware. Anything to reduce power usage and hardware cost is welcome in the data center world, and it will be interesting to see what kind of impact the open source hardware will have, especially when it comes to custom designs from system integrators. Intel is also working towards open source server hardware along with Facebook and the Open Compute Project. It is refreshing to see open source gaining traction in this market segment, to say the least.

Jitsi seems to be a lot of things, from an IM Client agglomerator such as Pidgin or Digsby, a combined XMPP and SIP VoIP client to a videoconferencing hub with all traffic encrypted using ZRTP. This Open Source software also claims integration with Microsoft Outlook and Apple Address Book, putting it in competition with Skype on more than one front. Unfortunately it will not connect to all online SIP or XMPP provider but Jitsi does offer an open XMPP bridge to host video calls and as it is open source there is no reason you could not construct your own. With the release of version 2.0 a host of new features and improvements have been added which you can read about by following the links at Slashdot. They have also partnered with the FMJ Project to allow recording of sessions as well as other possible customization thanks to the developers Wiki.
"Among the most prominent new features people will find quality multi-party video conferences for XMPP, audio device hot-plugging, support for Outlook presence and calls, an overhauled user interface and support for the Opus and VP8 audio/video codec. Jitsi has lately shaped into one of the more viable open Skype Alternatives with features such as end-to-end ZRTP encryption for audio and video calls. The 2.0 version has been in the works for almost a year now, so this is an important step for the project."

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:
- Nokia Siemens Networks
- Texas Instruments
The new cooperative has announced four main goals for 2013:
- "Virtualization support with considerations for real-time performance, I/O optimization, robustness and heterogeneous operating environments on multi-core SoCs.
- Real-time operations and the Linux kernel optimizations for the control and data plane.
- Packet processing optimizations that maximize performance and minimize latency in data flows through the network.
- 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.
The full press release can be found below.
I say let the world go to hell

You can praise video games as art to justify its impact on your life – but do you really consider it art?
Best before the servers are taken down, because you're probably not playing it after.
Art allows the author to express their humanity and permits the user to consider that perspective. We become cultured when we experiment with and to some extent understand difficult human nature problems. Ideas are transmitted about topics which we cannot otherwise understand. We are affected positively as humans in society when these issues are raised in a safe medium.
Video games, unlike most other mediums, encourage the user to coat the creation with their own expressions. The player can influence the content through their dialogue and decision-tree choices. The player can accomplish challenges in their own unique way and talk about it over the water cooler. The player can also embed their own content as a direct form of expression. The medium will also mature as we further learn how to leverage interactivity to open a dialogue for these artistic topics in completely new ways and not necessarily in a single direction.
Consciously or otherwise – users will express themselves.
With all of the potential for art that the medium allows it is a shame that – time and time again – the industry and its users neuter its artistic capabilities in the name of greed, simplicity, or merely fear.

Last week, the founder of Linux – Linus Torvalds – gave a speech at the Aalto Center for Entrepreneurship. The aspect that most people picked up on was a certain disparaging statement towards NVIDIA. Since then, the video has spread rapidly around the Internet with critics for and against the statement. Linus does not believe that NVIDIA is easy to work with regarding Linux support, in short. NVIDIA PR recently responded to his statement in stating that the company is in fact heavily involved with Linux development, albeit mobile kernels.
NVIDIA stated in its PR release that supporting Linux is important to the company and they understand how important a positive Linux experience using NVIDIA hardware is. I don’t think anyone is surprised by that statement, but that was not all they said. The company stated that they are big supporters of the ARM Linux kernel with a claimed second most total lines changed and fourth highest number of changesets in the kernel.
The company uses proprietary drivers, but it does support GeForce, Quadro, and Tesla graphics cards under the Linux operating system. By using a common, proprietary driver, NVIDIA claims same-day support for new graphics cards and OpenGL versions for both Windows and Linux operating systems.
Linus’ rant started when an audience member asked about Optimus support under Linux. On that front, NVIDIA did not have a direct answer – only that when it launched laptops with Optimus, it was only supported on Windows 7. Allegedly, the company is working to make interaction between its drivers and the Bumblebee Open Source Project. The Bumblebee project is working to make Optimus-powered laptops work with Linux operating systems.
What do you think of the two statements by Linus and NVIDIA? Should NVIDIA be held accountable for Optimus support under Linux? Is the company doing enough to support the OS? Or is Linus wrong? Let us know in the comments below!
Personally, as much as I like Linux, I don’t think NVIDIA should have to go out of its way to support Optimus on Linux. At least, not until the Linux OS is the operating system that comes pre-installed on an Optimus notebook. At that point, it would be on NVIDIA to provide support. Until then, they don’t have to support it on aftermarket / third part operating systems. With that said, better Linux support couldn't hurt PR-wise. As far as Linux and NVIDIA working together in a more general sense, I think that the company could certainly do more for Linux on the desktop, especially being a Linux Foundation member, but I don't think they will until it is more financially viable to do so.
The full PR statement is available after the break.

Hack a Day linked to a program that could be of great use for anyone who manipulates and processes images, or anyone who wants to be able to make fractals very quickly. Utilizing the OpenGL Shader Language Reuben Carter developed a command line tool that processes images using NVIDIA GPUs. As we have talked about in the past on PC Perspective, GPUs are much better at this sort of parallel processing than a traditional CPU or the CPU portion on modern processors. Below is one obvious use of this program, the quick creation of complex fractals but this program can also process pre-exisiting images. Edge detection, colour transforms and perhaps even image recognition tasks can be completed with his software at a much faster speed than CPU bound image manipulation programs. If you are in that field, or looking to decorate your dorm room, you should grab his software via the GitHub link in the article.
"If you ever need to manipulate images really fast, or just want to make some pretty fractals, [Reuben] has just what you need. He developed a neat command line tool to send code to a graphics card and generate images using pixel shaders. Opposed to making these images with a CPU, a GPU processes every pixel in parallel, making image processing much faster."

Sure, this title is little more than a series of bad puns. That said, HP’s situation has recently seems like little more than a series of bad jokes itself. Over the last year, HP appears to have been their own biggest public image disaster: they purchased Palm to release a tablet without much platform support; they shut down and liquidate the tablet after seven weeks; they flirt with disbanding their entire profitable division and draw intense media discussion over the death of the entire PC industry; and they sharply change their mind and keep their division long after the media damage ends. Despite that spiraling-out-of-control story, HP has just recently made a surprisingly sensible decision: Open Source WebOS.
WebOS… Web Open Source… I get it now!
Obviously, we cannot tell exactly how good of a long-term decision it is for HP to support WebOS as an open project with the details we have now. A number of questions, not the least of which being about what open source license HP will use for their operating system, shroud the fate of WebOS as an open source platform. While I will not get excited yet, as I will not assume sensibility on the part of HP, it is entirely possible that HP can displace Android and Meego as the open mobile operating systems. Then again, it is entirely possible that HP can just crumble under Android and its other competitors and go back to cramming drops of ink into plastic containers and building large servers for corporate clients.
Depending on the license, as well as other factors, what do you think of WebOS as the open platform of choice?

One of the most useful features in Google’s Chrome web browser is the built in PDF reader. It is a feature that I use almost every day, and although I keep an install of Firefox’s Aurora browser as a backup I have yet to return to using Firefox as my main browser since first checking out Chrome.
For now though, the team has released PDF.js as a browser extension for the open source browser. In addition to the extension download, the source code is available on GitHub for anyone to view and edit.
PDF.js displaying a Dell service manual in PDF format.
As it is now, the PDF.js add-on rather basic, but is definitely off to a good start. You are able to navigate by sections or page thumbnails accessible by a mouse-over pop-up menu on the left of the window. Along the top are buttons for previous and next page, navigating to a specific page, zooming in and out, downloading, printing, and searching the PDF document.
During some informal testing using a 94 page Dell service manual in PDF form, scrolling was smooth enough until hitting a new page upon which there was a bit of lag. Navigating to specific pages was rather quick, however.
The PDF reader is off to a good start and I may have one more reason to switch back to Mozilla’s browser soon enough. What do you guys and gals think about built in PDF support, is it something you find useful during your daily browsing? If you're interested in checking it out for yourself, the extension is available for download here. Simply download this "pdf.js.xpi" file and install it (choose the Firefox or Aurora executable for installation if Windows does not assign the .xpi extension to Firefox automatically) using Firefox. Now navigate to a PDF file on any webpage to have it automatically open using PDF.js.

I have used Fedora since it was Fedora Core, which has been almost eight years now. Fedora is a community-supported distrobution that is sponsored by Red Hat. Fedora is known for being on the leading edge of technology at the time of shipment. Their release cycle is every 6 months and they are very transparent as to what will be included and excluded. Fedora has a huge community and tries to involve everyone and encourages participation. If you need any help with using Fedora or have any questions, they can be answered by; Frequently Asked Questions (FAQ), Documentation, IRC, and Mailing Lists.
Now that you have a brief idea about Fedora, lets get to the interview:
