Ubuntu certainly steals the show for end users but on the enterprise side it is Red Hat's that is the star, with Fedora being its flavour more suited to personal use. A brand new release has arrived today, which will give home sysadmins a bit of work to test for compatibility with their current systems. Thankfully the base kernel has not changed much, this release deals with patches that have been fully tested over the past six months along with updates to the software which comes with Fedora. The Inquirer makes mention of Ovirt, a virtual machine management program, JBoss Application Server 7 and enhancements in Openstack, all of which should be well received by professionals. They will also be happy to know that Red Hat's Beefy Miracle has stuck with the Gnome interface instead of switching to Unity.
"The Red Hat sponsored Fedora project serves as the proving ground for new features that eventually end up in the firm's Red Hat Enterprise Linux (RHEL) operating system. Now Red Hat has announced that it has released Fedora 17 including updates to Gnome, Eclipse, GIMP and Openstack along with numerous patches."

Two different stories today focus on how both major CPU vendors have allowed their support for the new features present in their architectures to fall behind for Linux OSes. From The Inquirer we hear about the how poor OpenCL support from AMD is leaving APU accelerated computing for Linux to lag behind Windows development. This goes far beyond purely graphical tasks and the complaints we have heard from gamers as OpenCL is a computing language that can handle far more than just pushing pixels. The two most common OpenCL applications that people are familiar with are the GPU clients for BOINC and Folding@Home, which enable you to chug work units on your graphics card or the graphics cores on your CPU. AMD's Neal Robinson who is the current senior director of Consumer Developer Support has taken up the challenge of promoting Linux OpenCL support from within AMD, so keep your eyes peeled for news from his team.
Intel's Ivy Bridge is no better according to Phoronix, as testing shows very little improvement on the default Ubuntu Unity desktop with Compiz. That is what allows Ubuntu users to show the iconic Desktop Cube on the Gnome desktop environment and using it shows negative effects on the general performance of the system. Switching to KDE and OpenGL generally resulted in better performance as did Xfce. Phoronix does not hold out much hope for the improvement of Compiz on Ivy Bridge processors or Intel's open source drivers for the near future, either for graphics or GPU accelerated computation.
"For AMD flaky Linux support isn't just a matter of gamers complaining, but now with its APUs, standard applications are simply not making use of the compute power that AMD needs to compete with Intel."

It seems the Gabe Newell doesn't like hearing that you can't game on Linux and is planning on releasing a Linux version of both Steam and the Source Engine. The implementation is planned to be natively supported by Linux with no need for Wine, Phoronix has seen it running with an install of Ubuntu and a Catalyst driver for the Radeon that was providing graphics. The Linux community has been waiting a long time for this day and now that Gabe is focusing his attention on this project there is hopes that it will soon come to fruition. Phoronix could not be happier.
"For those that have doubted the exclusive Phoronix claims for quite a while now that the Steam client and Source Engine are in fact being ported to Linux, the doubts can be nearly laid to rest. Even I began to wonder how long it would take before the clients for their popular games would be publicly released under Linux. However, after confirming the information perhaps a bit too soon, their level of Linux interest is much more clear after spending a day at their offices. A meeting topped off the day with Gabe Newell regarding Linux where he sounded more like a Linux saint than an ex-Microsoft employee. Valve does have some great plans for Linux beyond just shipping the client versions of Steam and their popular games on the Source Engine."

Phoronix revisited the performance the HD 7950 on the new Catalyst driver for Linux as it is no longer labelled as unsupported hardware. That means that not only are the default clocks correct, you can use aticonfig/amdconfig to overclock the cards if you so desire. The scaling of the card now matches the clock speed nicely and shows an improvement from the HD 6950 in the benchmarks. You might not be able to find a Linux game which will take advantage of the full feature set and power of the HD 7950 but the card is capable of far more than providing you with pixels to slaughter.
"Here are some updated benchmarks of the AMD Radeon HD 7950 "Southern Islands" graphics card under Linux with the proprietary Catalyst driver."

Red Hat becomes the first Linux company to be worth over a billion dollars (edit for clarity: I meant take in over a billion dollars in revenue) with $1.13 billion in revenue last year.
Red Hat, Inc. is an open source software company based in Raleigh, North Carolina. The company’s identity is primarily with their current flagship product, Red Hat Enterprise Linux -- and a Cornell University lacrosse hat. The company also sponsors and holds liability over the Fedora Project which counterbalances Enterprise Linux by providing a free and community-supported operating system.
Just for clarification, that’s a rich penguin, not a rich drake.
Red Hat reported earnings of $1.13 billion dollars in revenue with $146.6 million in earnings. Subscriptions of Red Hat Enterprise Linux were declared responsible for $965.6 million dollars of their total revenue.
ZDNet has also reported that Linux is progressively eating market share from UNIX and Windows for servers shipped with preinstalled operating systems. Red Hat and other Linux vendors are progressively getting more of the same treatment as Microsoft has enjoyed in the past.
The future is bright for Linux, which is unfortunate due to the hole in the Ozone layer over Antarctica. Maybe the rest of the $1.13 billion is sales of sunscreen?

Tagged: OS, linux kernel 3.3, linux, kernel, Android
Linux kernel 3.3 has recently been released for public consumption, and it features quite a few new features and improvements. The kernel is the code that developers than build upon to create all the various Linux distributions such as Fedora, Mint, and Arch Linux (among others).
This latest release, version 3.3 includes various improvements to the file system, btrfs, networking, architecture, and EFI BIOS support. In regards to the file system, the Linux 3.3 kernel supports improved balancing and the ability to re-stripe between different RAID (redundant array of independent disks) levels. Further, the kernel will now allow an x86 boot image to be processed by EFI firmware in addition to the traditional BIOS microcode boot that is present in the majority of today's machines. Also, Kernel 3.3 improves the networking aspects by improving the ability to bond multiple NICs to improve networking throughput and/or to provide redundant connections. Support for a new architecture has also emerged such that Linux kernel will work with Texas Instruments C6X based chips. These chips include the "family of C64x single and multicore DSPs."
The above improvements are just the tip of the iceberg, however. The most talked about new feature is likely going to be the inclusion of Android code from Google's Android OS project. According to the Kernel Newbies website, the disagreements between Linux kernel developers and Google have been "ironed out," and code from the Android project will now start to be rolled back into the Linux kernel. They expect that Android coming home to traditional Linux will make developing code and end user software easier for everyone, and they expect further Android and Linux integration in the future.
More information on the latest Linux kernel release is available here.

After a delay of several weeks AMD has finally released a hot fix for Linux to allow for the usage of their new generation of video cards but they've not provided updates that can be rolled into the Linux kernel DRM driver, the X.Org DDX driver, or the new Gallium3D driver. However, since the new features seem to have been enabled with this hot fix, Phoronix picked up an XFX Radeon HD 7950 Black 3GB to test for performance on Ubuntu 12.04 LTS. The good news is that they saw 40~50%+ faster performance than an HD6950 but unfortunately not at stock speeds, the driver did not fully recognize the card and would not let them set the GPU and memory speeds to their full defaults.
"The Radeon HD 7900 series were announced at the end of 2011 and since then the Linux support status for this hardware has remained a big question. For the Radeon HD 7000 series "Southern Islands" GPU launch, they did not send over any hardware samples so Linux consumers have left to be confused over the state of the non-Windows support for AMD's hardware based on the "Graphics Core Next" architecture. Fortunately, here is finally an extensive look at the Radeon HD 7000 series on Linux with testing of a Radeon HD 7950."

It seems that not all is sweets (pie, of course) and celebration for the folks over at the Raspberry Pi Foundation, as the initial batch of their ARM powered Linux computers have experienced what the charity has dubbed a “hiccup” at the manufacturing stage. It seems that while they specified magnetic jacks in the design materials, the wrong RJ45 network jacks for the boards were soldered on accidentally by the Chinese factory. According to the Raspberry Pi Foundation, the dud jacks in question were the result of the manufacturer using non magnetic jacks instead of RJ45 connectors with integrated magnetic connections. They further stated that they had been aware of the problem for four days prior to the announcement, but needed to “do some further tests to make sure nothing else was affected.”
They are currently sourcing the proper network jacks, and are receiving help from their manufacturing and distribution partners RS Components and Premier Farnell. It is not all bad news; however, as it seems they caught the issue quickly enough to maintain the release schedule for the initial batch of Raspberry Pi boards. The issue is a relatively minor one that is easily rectified by desoldering the dud jacks and soldering on the new ones with integrated magnetics. The manufacturing factory is nearly finished with the replacement on the initial batch and they expect the boards to get out to consumers on time. The less than ideal news is that, there may be a slight delay for those waiting on pre-orders of boards outside of the initial batch as they are still trying to source enough networking jacks as mentioned above.
'We are very, very sorry.” they stated in the blog post. In the end, they believe it to be a mere small bump in the road and have promised to keep users updated on the manufacturing status of the eagerly awaited Raspberry Pi computers. More information along with X-rays of the dud networking jacks can be found on their blog.

The Raspberry Pi Foundation has quite the success on their hands with the small ARM powered Linux computer they have dubbed the Raspberry Pi. With pre-orders that sold out within hours, a great deal of press coverage, and overwhelming support from the community to support the Raspberry Pi with software and download mirrors, they have announced not only the promised Fedora 14 Remix Linux distribution, but OpenELEC XBMC support and an Arch Linux distro for power users.
So far, the charity has released the Fedora 14 Remix, Debian Squeeze, and Arch Linux distributions. All three are now available for download via their downloads page using either Torrent files or HTTP downloads through the community mirrors.
The Fedora Remix Distro
The Debian Squeeze OS is the Raspberry Pi's reference file system and is aimed at software developers while the Fedora Remix is aimed at those wanting a casual OS that is capable of playing back multimedia content. Finally, the Arch Linux distro is aimed at power users and Linux enthusiasts that want to totally customize their Linux operating system and the software including with it. These distros are meant to be installed on an SD card and then inserted into the Raspberry Pi.
Head on over to their downloads page to get your hands on the distros!
In a recent press release, the Linux Foundation added four new members, one of which is a big deal in the graphics card industry. In addition to the new members of Fluendo, Lineo Solutions, and Mocana is the green GPU powerhouse NVIDIA. According to Maximum PC, there is talk around the web of the company moving to open source graphics drivers; however, NVIDIA has not released anything to officially confirm or deny.
The Linux Foundation's Logo
Such a move would be rather extreme and unlikely, but it would certainly be one that is welcomed by the Linux community. Officially, the Vice President of Linux Platform Software Scott Pritchett stated the company is "strongly committed" to delivering quality software/hardware experiences and they hope their membership in the Linux Foundation will "accelerate our collaboration with the organizations and individuals instrumental in shaping the future of Linux." Further, they hope to be able to add to and enhance the user and development experience of the open source operating system.
The three other members to join the Linux Foundation specialize in multimedia software (Fluendo), embedded system development (Lineo Solutions), and device-agnostic security (Mocana) but the green giant that is NVIDIA has certainly stolen the show and is the big announcement for them (which isn't a bad thing that they joined, it is kind of a big deal to have them). Amanda McPherson, VP of Marketing and Developer Services for the Linux Foundation wrapped up the press release by saying that all of the new members "represent important areas of the Linux ecosystem and their contributions will immediately help advance the operating system.”
NVIDIA has generally enjoyed good support on the major Linux distributions, but now that they are a member here's hoping they can further improve their Linux graphics card drivers. What is your take on the Linux Foundation's new members, will they make a difference?
