  • From Clouds to Cars to Kitchens, Linux Making an Impact Everywhere

    There’s no operating system more ubiquitous than Linux. It’s everywhere. It’s even running in devices and computers you may not suspect—our cars, our cell phones, even our refrigerators. Linux supports businesses and organizations everywhere, and because it underpins open-source innovation, it is the platform of choice for new applications. Companies such as IBM and their work with organizations like the OpenPOWER Foundation are creating such new innovations as Big Blue’s new scale-out servers running Linux and putting them in places all around us. In fact, eWEEK recently ran a slide show depicting how prevalent the operating system is in the supercomputing space. Linux has quickly become the operating system of choice in the high performance computing (HPC) market, growing from relative obscurity 15 years ago to powering 97 percent of the fastest computers in the world. But its appeal is found in more than cost or choice. This list, compiled with assistance from IBM, provides some examples of where Linux is making an impact.

  • ARM’s first 64-bit servers: Just what can you expect to run on them?

    That’s what is being worked on by Linaro, an engineering group supported by a range of ARM-based chip designers, server OEMs and Linux operating system custodians, all of which share an interest in broadening the range of open-source software for the ARM platform.

    By the time the first 64-bit ARM-based SoCs become generally available for use in production servers later this year, Linaro is confident that certain core enterprise software packages used for serving websites, data analytics and databases will be running acceptably on the 64-bit ARM-based architecture.

    These enterprise software packages include the LAMP stack – an acronym for software widely used for websites, commonly referring to a Linux OS, Apache web server, MySQL database and PHP scripts – as well as the NoSQL database MongoDB and the distributed storage and processing framework Hadoop, together with other web-serving technologies such as memcached and HAProxy.

  • Why Use Linux for Device Drivers?

    The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. The success of Linux is clearly a testament to its technical quality and to the numerous benefits of free software in general. But for many, the true key to its success lies in the fact that it has brought the fun back to computing.

    One of the authors of the book Linux Device Drivers is quite clear about the fun aspects of playing with Linux. In the introduction to the book, Jonathan Corbet noted that, “The true key to the Linux success lies in the fact that it has brought the fun back to computing.” Corbet insists that Linux is a system where technical excellence is king. “With Linux, anybody can get their hands into the system and play in a sandbox where contributions from any direction are welcome, but where technical excellence is valued above all else.”

  • UK Surveillance Bill: giving up privacy for security but with no guarantee of security

    By now, people are aware of at least some the spying being conducted by the NSA and the GCHQ. The two programs working together form the largest data collection project in human history.

    • Reglue: Opening Up the World to Deserving Kids, One Linux Computer at a Time

      They say you never forget your first computer. For some of us, it was a Commodore 64 or an Apple IIe. For others, it was a Pentium 233 running Windows 95. Regardless of the hardware, the fond memories of wonder and excitement are universal. For me, I’ll never forget the night my father brought home our first computer, a Tandy 1000. Nor will I forget the curious excitement I felt toward the mysterious beige box that took up a large portion of the guest bedroom. This happened at a time when simply having a computer at home gave a school-age child an advantage. I have no doubt my experiences from that time positively influenced my path in life.

      In the decades that have passed since the beginning of the personal computer revolution, computers have gone from being a rare and expensive luxury to a mandatory educational tool. Today, a child without access to a computer (and the Internet) at home is at a disadvantage before he or she ever sets foot in a classroom. The unfortunate reality is that in an age where computer skills are no longer optional, far too many families don’t possess the resources to have a computer at home.

    • CoreOS Stabilizes Cloud Container Linux Operating System

      The open-source CoreOS Linux operating system hit a major milestone on July 25, issuing its first stable release. CoreOS is an Andreessen Horowitz-backed startup that offers the promise of a highly available operating system platform that is fully integrated with the Docker container virtualization technology.

    • Linux Top 3: CoreOS Goes Stable, Oracle Clones RHEL 7 and Tails Updates
    • Cloudy CoreOS Linux distro declares itself production-ready

      The developers behind the stripped-down CoreOS Linux distribution have pushed version 367.1.0 to the Stable release channel, marking the first time the project has delivered a production-ready release.

    • Bright Computing raises $14.5M to expand services for Linux cluster management

      Bright Computing, which helps companies manage Linux clusters, has picked up $14.5 million in Series B funding.

      The funding is an indication of how much demand there is, in modern corporate computing environments, for clusters of servers that can grow to include hundreds or even thousands of nodes. That’s because of the increased popularity of Hadoop and other clustered storage technologies, which help companies store enormous quantities of often unstructured data on cheap commodity servers, rather than the more-expensive storage area networks and dedicated storage hardware that an earlier generation of data center architects preferred.

    • Radio Free HPC Looks at the Need for Better Resource Management in Linux

      In this podcast, the Radio Free HPC teams looks at Henry Newman’s recent straw proposal for better resource management for Linux in HPC.

    • Who’s using Docker?

      I’ve spent the last couple of months working an internship for The Linux Foundation, doing research on new developments and adoption trends in the open source industry. If you have spent any amount of time reading about open source over the last year, you have probably heard about Docker; a lot of people are talking about it these days and the impact it’s going to have on virtualization and DevOps.

      With new technologies like this, it can often be challenging to filter out the hype and understand the practical implications. Additionally, complex jargon often makes subjects like Linux containers confusing to the layman and limits discussion to those who are deeply knowledgeable on the subject. With this article, I will step back for a moment from the discussion of what Docker can do to focus on how it is changing the Linux landscape.

    • The Shocking Truth About Torvalds’ Home Office

      “I am really incredibly surprised that my work space is very similar to Linus’ and also the working hours are almost identical,” said Google+ blogger Rodolfo Saenz. In Saenz’s setup, though, “the treadmill stands alone. I use it religiously every day, but I don’t like to mix work with exercise. I climb on the treadmill to clean my mind, listen to music and think about many things.”

    • Linux 3.16-rc7 released; final may be tagged next week
    • My First Unikernel

      Unikernels promise some interesting benefits. The Ubuntu 14.04 amd64-disk1.img cloud image is 243 MB unconfigured, while the unikernel ended up at just 5.2 MB (running the queue service). Ubuntu runs a large amount of C code in security-critical places, while the unikernel is almost entirely type-safe OCaml. And besides, trying new things is fun.

      • Updated Source Engine Benchmarks On The Latest AMD/NVIDIA Linux Drivers

        Benchmarks of Valve’s Source Engine games (and other Steam titles for that matter) aren’t done in all Phoronix driver tests and graphics card articles for various reasons, among which is that there’s other more GPU-demanding OpenGL tests to utilize for modern hardware. However, for those curious about the performance of various AMD Radeon and NVIDIA GeForce graphics cards using the latest proprietary drivers, here’s some updated numbers.

      • NVIDIA Is Working Towards VDPAU H.265/HEVC Support

        NVIDIA is working on adding HEVC/H.265 video decoding support to VDPAU.

        NVIDIA developers are extending the “Video Decode and Presentation API for Unix” interfaces to allow the HEVC/H.265 requirements. The work aims to enable hardware-accelerated decoding of HEVC content under VDPAU and to provide a reference implementation for this video decoding. José Hiram Soltren, the developer that worked on this support, is also working on a HEVC decode patch for FFmpeg and MPlayer based upon the new API.

      • Layout Guidelines: A quick example

        The guidelines suggest layout patterns for simple, complex and very complex command structures. So where does our calendar app fit? Well, I wasn’t quite sure either. And that’s ok! Some things are tough to know until you start delving into the design work. The guidelines suggest starting with a pattern for a simple command structure when you’re not sure. So that’s what I did. As I started putting together a design and thinking about how Sue would use it for the purposes described, it became clear that not only were there several other desirable functions (like switching calendars, setting up calendar accounts, setting calendar colors, and more) but there are also certain commands Sue might use quite often (like switching between a day, week and month view of her schedule, adding an event and quickly getting back to today after browsing forward or back in time). So I settled on the suggested Toolbar + Menu Button command pattern for a complex command structure.

      • A talk in 9 images

        My talk at GUADEC this year was about GTK+ dialogs. The first half of the talk consisted of a comparison of dialogs in GTK+ 2, in GTK+ 3 under gnome-shell and in GTK+ 3 under xfwm4 (as an example of an environment that does not favor client-side decorations).

      • Eye of GNOME 3.13.3 Features Improved GUI Test Handling

        According to the changelog, the deprecated GtkMisc and GtkAlignment usage has been dropped, the GUI test handling has been improved, the dialogs made with Glade have been converted to GResource and widget templates, disabling the dark theme plugin no longer disables the dark theme, and the plugin manager is now resizing in the preferences window.

      • GUADEC 2014, Day Three: GTK+ and Wayland

        The third day of GUADEC was mostly devoted to lower level parts of the GNOME stack. There were talks on GTK+, CSS, Wayland, and WebKitGTK+, but also an annual general meeting of the GNOME Foundation.

      • GUADEC 2014 Core Days Finish

      • GNOME Stakeholders Take Issue With Groupon Over their Gnome

        Earlier this year the Groupon discount web-site introduced Gnome, a tablet software solution for helping business owners run their business. This software is completely unrelated to the open-source GNOME desktop environment on Linux systems. The Groupon Gnome announcement reads, “Today we announced Gnome, a new tablet-based platform that will provide sophisticated tools to local merchants to run their businesses more effectively and understand their customers better. The tablet will let merchants instantly recognize their Groupon customers as they enter their business, seamlessly redeem Groupons and save time and money with a simple point of-sale system and credit card payment processing service. Gnome will soon integrate with popular accounting software programs such as QuickBooks and Xero and offer a suite of customer relationship management tools, including the ability to customize marketing campaigns based on purchase history, share customer feedback via social media and respond to customer inquiries or comments.”

      • GNOME/GTK On Wayland Gains Focus At GUADEC

        GTK+ and GNOME Wayland support were frequent focal discussion points at this year’s GUADEC — GNOME’s annual conference — for getting rid of X11.

  • Distributions

    • Minimal Linux Live

      Minimal Linux Live is a set of Linux shell scripts which automatically build minimal Live Linux OS based on Linux kernel and BusyBox. All necessary source codes are automatically downloaded and all build operations are fully encapsulated in the scripts.

    • Minimal Linux Live
    • Adventures in live booting Linux distributions

      Building highly customized live images isn’t easy and running them in production makes it more challenging. Once the upstream kernel has a stable, solid, stackable filesystem, it should be much easier to operate a live environment for extended periods. There has been a parade of stackable filesystems over the years (remember funion-fs?) but I’ve been told that overlayfs seems to be a solid contender. I’ll keep an eye out for those kernel patches to land upstream but I’m not going to hold my breath quite yet.

    • 10 reasons to try Zorin OS 9, the Linux OS that looks like Windows

      Zorin OS is an Ubuntu-based Linux distribution designed especially for newcomers to Linux. With a Windows-like interface and many programs similar to those found in Microsoft’s proprietary OS, it aims to make it easy for Windows users to get the most out of Linux.

      • Leaders are catalysts for shared purpose and results

        On every floor at Red Hat Tower in downtown Raleigh, you’ll find a brand message sign that describes Red Hat’s values and culture. On my floor, where I am an intern at Red Hat, the brand message is “Leaders are catalysts, turning shared purpose into shared results.” I see this sign multiple times everday. Coming into work. Going to meetings. Grabbing a coffee. It’s always there.

      • When Metrics Go Wrong

        In one open source project (on which I was a release manager), the main metric I cared about was the bugs open against a milestone. As time went on, and the number was not going down fast enough, we regularly would bump bugs to the next milestone, not because they were not important issues, but because we knew that they would not be fixed by the date we had set ourselves. Having participated in a number of projects, I have a pretty good idea that this is a universal tendency as release approaches.

        • Fedora 21 will feature “solarized” color schemes in both the Terminal and Gedit

          Recently, I have been using what will become Fedora 21 as my day-to-day machine, (side note: I have found it to be pretty stable for pre-release software). One really nice improvement that i am enjoying on Fedora 21 is the addition of the solarized color scheme in both the default terminal (gnome-terminal), and the default graphical text editior (gedit). Solarized comes in both light and dark variants, and really makes these applications look fantastic and works really well on a wide range of displays and screen brightness levels. From the solarized website:

      • The FFmpeg vs. Libav War Continues In Debian Land

        Long story short, due to security concerns, package incompatibility issues, and being too short of time before the Debian 8.0 Jessie release, and there’s some measurable resistance to adding FFmpeg back to the repository. However, others are after FFmpeg in Debian for features it has over Libav with regard to some codecs and other abilities, some programs not compiling against Libav, and other differences between it and the forked Libav project. Time will tell if/when FFmpeg will be allowed back in Debian and whether it will happen in time for the 8.0 Jessie releae.

      • Debian Squeeze Reaches Version 6.0.10

        This is the tenth major update and unfortunately the last one in the life of this branch of the Debian distribution. According to the official changelog this update corrects alot of security problems due to the old stable release and contains a few fixes for serious problems. It is very important to mention the fact that this major update of the Debian 6.x included all the security updates that have never been part of a point release.
