Fedora 21 has been released in three different flavours, each intended for a different usage scenario. The Server version is designed for exactly what it sounds like while the new Cloud version has a modular kernel which is more friendly for being run on remote hardware and is likely to show up in Microsoft Azure's choice of image in their IaaS interface. The Workstation version is the one that was examined at Linux.com and is likely to be the most common version installed by users. Fedora has always been a choice for the brave as they tend to be on the cutting edge and while that does mean that they offer features unavailable on other flavours of Linux there can be the occasional bug or other obstacles. Linux.com found only two so far, Nautilus aka Files stopped working and needed to be either reinstalled or preferably replaced with a better file manager. The other was an unclear GUI during the updated installation process which is easily avoided once you have seen the screen more than once. The positives far outnumber the negatives, this looks to be a great improvement on a solid OS and one which should retain its popularity with the software development crowd. Read the article for the full list of included software and improvements.
"Fedora is among the most respected Linux-based distributions. Known as a bleeding edge operating system it offers the latest technologies at the earliest stages. It’s also known for working with upstream projects instead of patching things downstream."

AMD showed off its first ARM-based “Seattle” processor running on a reference platform motherboard at an event in San Francisco earlier this week. The new chip, which began sampling in March, is slated for general availability in Q4 2014. The “Seattle” processor will be officially labeled the AMD Opteron A1100.
During the press event, AMD demonstrated the Opteron A1100 running on a reference design motherboard (the Seattle Development Platform). The hardware was used to drive a LAMP software stack including an ARM optimized version of Linux based on RHEL, Apache 2.4.6, MySQL 5.5.35, and PHP 5.4.16. The server was then used to host a WordPress blog that included stream-able video.
Of course, the hardware itself is the new and interesting bit and thanks to the event we now have quite a few details to share.
The Opteron A1100 features eight ARM Cortex-A57 cores clocked at 2.0 GHz (or higher). AMD has further packed in an integrated memory controller, TrustZone encryption hardware, and floating point and NEON video acceleration hardware. Like a true SoC, the Opteron A1100 supports 8 lanes of PCI-E 3.0, eight SATA III 6Gbps ports, and two 10GbE network connections.
The Seattle processor has a total of 4MB of L2 cache (each pair of cores shares 1MB of L2) and 8MB L3 cache that all eight cores share. The integrated memory controller supports DDR3 and DDR4 memory in SO-DIMM, unbuffered DIMM, and registered ECC RDIMM forms (only one type per motherboard) enabling the ARM-based platform to be used in a wide range of server environments (enterprise, SMB, and home servers et al).
AMD has stated that the upcoming Opteron A1100 processor delivers between two and four times the performance of the existing Opteron X series (which uses four x86 Jaguar cores clocked at 1.9 GHz). The A1100 has a 25W TDP and is manufactured by Global Foundries. Despite the slight increase in TDP versus the Opteron X series (the Opteron X2150 is a 22W part), AMD claims the increased performance results in notable improvements in compute/watt performance.
AMD has engineered a reference motherboard though partners will also be able to provide customized solutions. The combination of reference motherboard and ARM-based Opteron A1100 is known at the Seattle Development Platform. This reference motherboard features four registered DDR3 DIMM slots for up to 128GB of memory, eight SATA 6Gbps ports, support for standard ATX power supplies, and multiple PCI-E connectors that can be configured to run as a single PCI-E 3.0 x8 slot or two PCI-E 3.0 x4 slots.
The Opteron A1100 is an interesting move from AMD that will target low power servers. the ARM-based server chip has an uphill battle in challenging x86-64 in this space, but the SoC does have several advantages in terms of compute performance per watt and overall cost. AMD has taken the SoC elements (integrated IO, memory, companion processor hardware) of the Opteron X series and its APUs in general, removed the graphics portion, and crammed in as many low power 64-bit ARM cores as possible. This configuration will have advantages over the Opteron X CPU+GPU APU when running applications that use multiple serial threads and can take advantage of large amounts of memory per node (up to 128GB). The A1100 should excel in serving up files and web pages or acting as a caching server where data can be held in memory for fast access.
I am looking forward to the launch as the 64-bit ARM architecture makes its first major inroads into the server market. The benchmarks, and ultimately software stack support, will determine how well it is received and if it ends up being a successful product for AMD, but at the very least it keeps Intel on its toes and offers up an alternative and competitive option.

Tagged: linux, Fedora, heisenbug
Fedora 20 in a variety of flavours has arrived for anyone interested in trying out the newest version of this long standing Linux distro. They have native support for just about any desktop environment you could want without the need to release separate versions for each. It also offers full support for ARM processors, either small devices or multitudes of processors strung together into something a little more powerful. If you are uncertain about how much you trust the new OS, follow the comments at Slashdot to see what challenges people have encountered.
"The Fedora Project has announced the release of Fedora 20, code named Heisenbug (release notes). Fedora 20 is dedicated to Seth Vidal, the lead developer of Yum and the Fedora update repository, who recently died in a road accident. Gnome is the default DE of Fedora, and so it is for Fedora 20. However unlike Ubuntu (where they had to create different distros for each DE) Fedora comes with KDE, XFCE, LXDE and MATE. You can install the DE of your choice on top of base Fedora."

Phoronix just loves Linux benchmarking and have been very busy this year with not only the new Linux distros and kernels which have arrived this year but also testing Ivy Bridge's CPU and GPU performance on the open source OS. With the arrival of an updated Arch Linux they once again find themselves at the test bench, in this particular case a Sandy Bridge based system with an AMD GPU. Take a read through the five pages of benchmarks covering a wide variety of performance measurements and see if you might want to think about upgrading or switching your current version of Linux.
"At the request of many Phoronix readers following the release of updated Arch Linux media, here are some new Arch Linux benchmarks. However, this is not just Arch vs. Ubuntu, but rather a larger Linux distribution performance comparison. In this article are benchmark results from Ubuntu 12.04 LTS, CentOS 6.2, Fedora 17, Slackware 14.0 Beta, and Arch Linux."

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."

Tagged: Raspberry Pi, linux, fedora remix, Fedora, arm
The Raspberry Pi hardware is coming out at the end of this month, and the folks over at the Raspberry Pi Foundation are gearing up for the release. On their blog, they shared a video by Chis Tyler that I thought was rather interesting. In the accompanying video, he talked about the Raspberry Pi's Fedora Remix linux operating system.
The new Fedora Remix is being produced by Seneca College, and takes the traditional desktop Fedora Linux distribution and adapts it to run on the ARM platform. It will include several open source applications out of the box including a web browser, word processor, and several other tools for managing the OS and working with files. Mr. Tyler states that the Fedora Remix distro will closely resemble a traditional desktop experience when paired with a keyboard and mouse.
What I found interesting from the video was a statement by Paul Whalen, a software researcher for Fedora on ARM, where he talks about the Fedora licensing requiring applications to be built natively on the hardware that it will be used on. Because of that, they had to go out and construct a build farm of approximately 60 ARM devices including the Guru Plug. They design the software on workstation computers, and then send it to the build farm of ARM powered devices to be built and compiled into a native binary, and then is sent back. I thought that it was strange at first that they had to go about it in such a roundabout way but in the end it should help to have natively built applications performance wise.
In another exciting bit of news, Liz ended the Raspberry Pi blog post with an update on the status of the Linux computer's hardware.
They are still working on manufacturing the Raspberry Pis, and they "hope the Raspberry Pis from the first batch will be out of testing by the end of Thursday (ed: tomorrow at time of writing), and on their way to freight"
The Raspberry Pi is almost upon us! The non profit organization expects the SD card image download for the Fedora Remix distribution to be available in the next few days while the Cambridge Reference File System (Debian Squeeze based OS) image is available to download now.

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:
