Recruitment
-
The foundation thinks that a natural way of promoting the participation of younger people in the Linux kernel development is to reach out to colleges and universities to host training activities where students and faculty learn the ropes of how to contribute to the kernel.
-
Version 3.13
-
There’s many exciting Linux 3.13 kernel features already, but we have another one to talk about today. In the input subsystem update for 3.13, support for the Neonode zForce has been added, an interesting touch-screen technology based on infrared light fields.
-
The Kernel-based Virtual Machine updates for the Linux 3.13 kernel were filed today and includes a fair amount of improvements for virtualization on PowerPC hardware, but there’s also some x86 improvements too.
-
While the merge window for the Linux 3.13 kernel isn’t even over yet, this next major kernel update is already looking to be rather exciting with a number of new features.
-
For those in need of a high-performance specially-optimized file-system for flash storage devices, the F2FS file-system developed at Samsung has seen more “major enhancements” queued up for the Linux 3.13 kernel.
-
The merge window hasn’t even officially opened yet on the Linux 3.13 kernel but it’s already super exciting and I can’t wait for the new code to start hitting mainline and to benchmark these massive changes to the Linux kernel. Here’s just a few things to expect so far but it’s already gearing up to be a super exciting release and perhaps the best of 2013.
More Development
-
AMD has just published a new set of Linux kernel patches, revealing Linux support for a Cryptographic Coprocessor (AMD CCP).
-
The btrfs-progs user-space component to the Btrfs file-system has seen a number of commits in recent weeks. Beyond lots of code improvements and bug-fixes, the default meta-data block size was changed for the Btrfs mkfs command.
Events
-
The 3.12 Linux kernel release this week brought with it many new features including multi-threaded RAID5 support in the MD subsystem, the addition of render nodes, and TSO sizing.
-
-
The Linux Foundation is preparing to host its third LinuxCon Europe and this year for the first time will also host CloudOpen in Europe. The combination of the two events along with a variety of other co-located events taking place next week represents the largest gathering of Linux and open cloud professionals in Europe. From KVM Forum & oVirt Workshop to Xen Project Developer Summit and Yocto Developer Day to the Open Compute Engineering Workshop, there is something for everyone.
-
Linux Foundation Training scholarship winner Abdelghani Ouchabane is a senior software developer at eZono, a medical device startup in Germany that uses Linux to build its software and systems. He’s worked on a range of Linux projects over the past five years in this job, including kernel module and driver configuration, system and server configuration, and networking, he said. He’s also contributed to many open source projects including Fedora, CentOS, Ubuntu, Meego, Tizen and Debian.
Graphics Stack
-
Yesterday there was news that OpenACC 2.0 parallel programming support was coming to GCC complete with GPU acceleration support for NVIDIA GPUs. While it was exciting on the surface, it appears that this work may be poisonous and could have a very tough time making it upstream.
The news yesterday was about Oak Ridge, Mentor Graphics, and NVIDIA working to add OpenACC 2.0 parallel programming support to the GCC compiler for C and Fortran. GCC right now doesn’t have any support for OpenACC, even the older versions of the specification, and the patches thus far haven’t fully exploited the GPU potential besides converting OpenACC to OpenCL or another implementation that just runs OpenACC over OpenMP on the CPU. Mentor Graphics is now responsible for bringing OpenACC 2.0 with NVIDIA GPU support to the GNU Compiler Collection.
-
The xf86-video-freedreno X.Org driver for providing support for Qualcomm’s Adreno/Snapdragon graphics hardware has reached version 1.0 in its first stable release.
-
After the support has been within Wayland’s Weston reference compositor for several months, developers have now added sub-surfaces support to the Wayland core protocol itself. Wayland sub-surfaces can make for efficient use of video players and windowed OpenGL games on Wayland.
-
-
Interesting in the Wayland camp this week has been lots of discussions about the XDG-Shell proposal but besides that, a patch-set just appeared that finally adds alt-tab support to Wayland’s Weston compositor and also updates the exposay feature.
-
As part of the recent Radeon Rx 200 series and Hawaii GPU launch, AMD also unveiled Mantle as a new graphics rendering API to compete with OpenGL and Direct3D. AMD claims Mantle is easier, faster, and all-around better than OpenGL for game engines and other purposes. This week AMD has renewed their push that they want to see Mantle on Linux and other platforms.
-
The xf86-video-intel 3.0 driver is still on the way and Intel OTC’s Chris Wilson has put out today its latest development release that has stability fixes, including further TearFree updates.
-
If you are after a low-end graphics card for use on Linux, up for review today is the Zotac GeForce GT 610 Synergy 1GB graphics card that sells for less than $50 USD. The results in this Linux hardware review compare the GT 610 to a range of other AMD Radeon and NVIDIA GeForce graphics cards using the proprietary drivers under Ubuntu Linux. Even if you’re not interested in the GT 610, this article makes for a nice 12-way Linux graphics card comparison with the very latest AMD/NVIDIA GPU drivers.
-
If you’re curious about the state of the Qt5-powered Hawaii Desktop running natively on Wayland, a new video has been uploaded that nicely shows off this new Linux desktop alternative that’s designed around Wayland.
Benchmarks
-
For your viewing pleasure today is a 13-way AMD Radeon graphics card comparison when testing out the open-source Radeon Gallium3D drivers on the wide spectrum of ATI/AMD GPUs while looking at the performance for Valve’s Source Engine with Counter-Strike: Source and Team Fortress 2. Given the imminent arrival of Steam Machines and SteamOS to push Linux gaming into its long-awaited spotlight, is AMD’s open-source Linux graphics driver capable of delivering a reasonable level of performance?For your viewing pleasure today is a 13-way AMD Radeon graphics card comparison when testing out the open-source Radeon Gallium3D drivers on the wide spectrum of ATI/AMD GPUs while looking at the performance for Valve’s Source Engine with Counter-Strike: Source and Team Fortress 2.

Last week AMD released the Radeon R9 290 “Hawaii” graphics card. The R9 290 is a cut-down R9 290X and sells for just $399 USD. Here are the first Linux benchmarks of the AMD R9 290 using Ubuntu 13.10!
-
Red Hat Enterprise Linux 6.4, Amazon Linux AMI 2013.09, Ubuntu 12.04.3 LTS, Ubuntu 13.10, and SUSE Linux Enterprise 11 have been pitted against each other in Amazon’s Elastic Compute Cloud (EC2) and the Linux performance benchmark results are now available.
-
This testing isn’t too different from other open vs. closed-source GPU driver benchmarks run recently on Phoronix but is a fresh look and with some different tests. The Catalyst driver in use was the latest publicly available (Catalyst 13.11 Beta 6 – OpenGL 4.3.12614 – fglrx 13.25.5) and the open-source version was Mesa 10.0-devel with an xf86-video-ati Git snapshot. The Linux 3.12 kernel was used throughout all testing and DPM was enabled for the Radeon Linux driver.

Many programs exist that try to serve as a replacement for MATLAB. They all differ in their capabilities—some extending beyond what is available in MATLAB, and others giving subsets of functions that focus on some problem area. In this article, let’s look at another available option: FreeMat.
[...]
The main Web site for FreeMat is hosted on SourceForge. Installation for most Linux distributions should be as easy as using your friendly neighborhood package manager.

Lisp is one of those languages that people either love or hate. Count me among the Lisp lovers. I was brainwashed during my undergraduate studies at MIT to believe that Lisp is the only “real” programming language out there, and that anything else is a pale imitation. True, I use Python and Ruby in my day-to-day work, but I often wish I had the chance to work with Lisp on a regular basis.

Want to get involved in a cool new initiative to promote it across Europe?
My Young Advisors are a talented group of people advising and supporting me in my work. And they’ve been hard at work themselves. They’ve come up with a great idea: Europe Code Week – a week of initiatives at the end of November (25th-30th) with a focus on coding – workshops, teaching, or just raising awareness.

It’s funny, when your home office is your couch, you tend to forget how nice it can be when you dock a laptop and have all the extra screen real estate a monitor brings. For many years, I left my work laptop docked at work, and when I worked from home, I just VPNed in with a personal laptop. Lately though, I’ve recognized the benefits of splitting personal life and work, so I’ve taken to carrying my laptop with me when I go to and from the office. Because we invested in a docking station, it’s relatively simple to transition between a laptop on my lap and a laptop on a desk with an extra monitor—except for one little thing: my external monitor is in portrait mode.

A startling fact is that there are in excess of a billion people who have some type of disability. That represents approximately 15% of the world’s population with a physical, sensory or mental limitation that interferes with their ability to move, see, hear or learn. 350 million people in the world are partially sighted or blind. The faster computer technology evolves, the more excluded these individuals would become without development in computer software that seeks to address their needs.

Whether you are actively considering a move away from Photoshop, or simply hoping there is a non-proprietary tool for reading your Photoshop images if you ever decide to stop subscribing to Adobe’s cloud, you’ve probably wondered about GIMP. A free, open-source, image editor, the GNU Image Manipulation Program (GIMP) has been a go-to tool for Linux users for years, but has a reputation for being hard to use and lacking many of Photoshop’s features. The reality has changed dramatically over the last couple years. GIMP now has a very competent user interface, as well as an extensive and powerful set of features. Its openly extensible nature means that in some areas, like running well-known image processing algorithms on your photos, it actually outshines Adobe Photoshop.

I was disappointed with the “beta” release for GNU/Linux. It seemed “alpha” to me and was very awkward to install. There’s news of a new release for December, synchronized for That Other OS and GNU/Linux. It should be smoother this time. Perhaps I’ll really get to do something with it.

With past ISP problems, I’ve been able to run a continuous ping to an outside IP address and show the tech-support representative that I have packet loss. Unfortunately, a running ping command doesn’t give a history of when the packets are lost. With SmokePing, not only is there a record of when packets are lost, but there’s also a graphical representation of how many packets were lost, and from several IP addresses to boot.

I spent the past year writing The Librarian’s Guide to Academic Research in the Cloud, a book which focuses on using and thinking about cloud services in an academic research context. I’m fortunate enough to belong to a union that negotiated research leave for new faculty, and that leave made the book possible.

Keeping a daily journal is one of the best ways to keep your thoughts organized. Not only can it help you think more clearly, it can also help you reflect on your past actions. After writing for a while, you’ll get used to putting your thoughts in text form and reflecting upon them. Journaling isn’t something new, though. The act of writing a journal has been practiced for centuries. However, it is now that this lost art form is regaining its popularity.

We cut the cord a couple of years ago, the need to get TV over traditional TV Ariel was no longer needed and services such as TV Catchup, iPlayer and the other UK Catchup TV Channels streamed over the net to my TV were all we needed.

Ubuntu 13.10′s new Scopes feature is fed by heuristics to offer matches to your accumulated browsing and search requests gleaned from Github, reddit, Wikipedia, Flickr, Google News, The Weather Channel and Yelp. I find this level of search invasion too intrusive. If I wanted that approach to marketing, I would just bypass Ubuntu completely and grab a Kindle or rely more fully on the Google search engine.

Looking back on my time with Kubuntu 13.10 the thing which stood out the most was that not much stood out. Apart from having some network issues which slowed things down during my first installation attempt, my time with the distribution was quite good. The installer is nicely laid out, the KDE 4.11 desktop is quite polished, providing a clean, feature-rich environment. I like that Kubuntu comes with a guest account for those odd times people wish to borrow my computer. I’m also happy to see there is an option in the KDE System Settings panel to turn off the guest account for people who see the guest account as a security concern. The new user account manager is slick and easy to use, I’m quite happy to see it included in this release. So far I’m tentatively happy with the new Discover software manager. It looks pretty and it seems to work well enough. The software manager’s interface is a little busy for my taste, but otherwise I have no complaints. I think most people will take to it and those who don’t can fall back on the older package manager. Overall, Kubuntu 13.10 feels like a stable, mature release that has some nice new features, but nothing ground shaking that would put off existing users. I’m actually sorry this version is not a long-term support release and will only receive security updates for nine months, the short support cycle seems to be the only weak point in an otherwise excellent desktop operating system.

I try to write articles for the readers on this site that I hope they will find useful and so I agreed to write the review on the basis that if it is a great book then I can share that knowledge and if it isn’t then I can also share that knowledge.

Today in Open Source: SteamOS will not be based on Ubuntu. Plus: Metro Last Light out for Linux, and the Tuxmachines site has been sold
[...]
Tuxmachines Site Sold
Foss Force is reporting that the Tuxmachines site has been sold. Here it is in case you missed it last month.
One of the most popular Linux sites, Tuxmachines.org, announced on October 28th that it has been tentatively sold for $1,000.
When Ms. Linton, who has also been involved with DistroWatch, started Tuxmachines it quickly grew to be an important destination on news about Linux and other open source projects.
More at Foss Force
It’s sad that the site is changing hands, but hopefully the new owner will keep it going for a long, long time.

So we found ourselves on unsure footing. While I am sure that the developers of Mint and Zorin are confident in their longevity within the the community…..
It’s simply a risk we cannot take. They are both some of the best examples of what Linux is and should be on the desktop. Both of these distributions will be used in our Reglue computers, as each of them has a specified purpose, depending on the power and size of the computer being installed.
