Recruitment

Version 3.13

  • Linux 3.13 Supports The Neonode zForce

    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.

  • KVM Pushes Linux Virtualization Forward In Linux 3.13

    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.

  • 13 Reasons Linux 3.13 Is Going To Be Very Exciting

    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.

  • F2FS File-System Major Linux 3.13 Enhancements

    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 Linux 3.13 Kernel Is Already Super Exciting

    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

Events

Graphics Stack

  • NVIDIA, Mentor Graphics May Harm GCC

    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.

  • Freedreno Graphics Driver Reaches Version 1.0

    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.

  • Sub-Surfaces Support Added To Wayland Protocol

    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.

  • Alt-Tab Support, Exposay For Wayland’s Weston

    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.

  • AMD Wants Mantle On Linux, OS X, Mobile Devices

    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.

  • Intel X.Org Driver Released With New Stability Fixes

    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.

  • NVIDIA GeForce GT 610 On Linux

    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.

  • Video Showing Off Hawaii Desktop Running On Wayland

    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

  • 13-Way AMD GPU Open-Source Linux Driver Comparison On The Source Engine

    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.

  • AMD Radeon R9 290 Benchmarks On Ubuntu Linux

    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!

  • 5-Way Amazon EC2 Cloud Linux OS Benchmarks

    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.

  • 8-Way AMD Gallium3D vs. Catalyst Ubuntu GPU Benchmarks

    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.

  • FreeMat—Yet Another MATLAB Replacement

    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.

  • Red Hat Puts Out Ceylon 1.0 Language, Compiler

    Red Hat is out this week with their first production release of Ceylon, a modular, modern, and statically-typed programming language for Java and JavaScript Virtual Machines. Ceylon 1.0 consists of a language specification, compiler, and Eclipse IDE integration.

    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.

Canonical/Ubuntu News for November

Posted in News Roundup at 6:14 am by Dr. Roy Schestowitz

  • Ubuntu’s Saucy Salamander is a Slick but Spiritless Upgrade

    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.

  • Ubuntu 13.10: A desktop tour (Slideshow)

    The most new-user friendly of all Linux desktop distributions, Ubuntu has a new, better release: Ubuntu 13.10, Saucy Salamander.

  • Mark Shuttleworth Apologizes for the Trademark Infringement Letter Sent to Fixubuntu.com
  • Mark Shuttleworth Regrets the “Tea Party” Remarks and Other Canonical Mistakes
  • Mark Shuttleworth Sends Out Apologies
  • Ubuntu 13.10 – meeting the Saucy Salamander

    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.

  • A review of “Instant Ubuntu”

    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.

  • Install Everpad 2.5.6 in Ubuntu 13.10
  • Install Cairo Dock 3.3.2 in Ubuntu 13.10
  • Valve’s SteamOS will not be based on Ubuntu

    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.

  • Installation and disk partitioning guide for Ubuntu 13.10
  • How-to configure keyboard layouts in Ubuntu Unity (video)
  • Install Ubuntu 13.10 using a USB key from Window or another Linux distribution

    A USB key or thumb drive or USB stick is the best device to use in installing your favorite Linux distribution. It’s not just because it’s reusable forever (unless you mess it up), but the system runs much faster than if you used a CD or DVD disc for installation.

  • Grsync : Graphical rsync backup tool on Ubuntu ( 12.10 / 13.04 / 13.10)

    grsync is a graphical rsync tool in ubuntu linux. It provides a graphical user interface to backup or sync important files & directories to remote machine or in local machine using rsync. It currently supports only a limited set of the most important rsync features, but can be used effectively for local directory synchronization.

  • Flavours and Variants

    • Pear OS 8 Has Been Officially Released

      The highly anticipated Pear OS 8 Linux distribution has been officially released today, November 9, by David Tavares, the father of the Pear Linux Project.

      There’s no official announcement for Pear OS 8, but we can tell you that the distribution boasts a new iOS 7 design, created by Ivan Matias Suarez. Moreover, the brand-new Pear OS 8 distribution features a set of pre-installed applications, including Pear Cloud, Clean My Pear 2, MyPear 6, as well as more than 3,000 downloadable packages from its generous software repository.

    • Pear OS 8 Could Arrive for Microsoft Surface Tablet

      David Tavares, father of the Pear Linux project, has just announced that he started a crowdfunding campaign for a new project, called Pear OS 8 Tablet Edition, a version of the Pear OS 8 Linux operating system for the Microsoft Surface tablet.

    • Taming The Iguana…..

      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.
