  • Docker: Making the Internet Programmable

    Docker, and containers in general, are hot technologies that have been getting quite a bit of attention over the past few years. Even Solomon Hykes, Founder, CTO, and Chief Product Officer at Docker started his keynote with the assumption that people attending LinuxCon Europe know that Docker does containers, so instead of focusing on what Docker does, Hykes used his time to talk about Docker’s purpose saying, “It really boils down to one small sentence. We're trying to make the Internet programmable.”

    Hykes described this idea of making the Internet programmable with three key points. First, they are focused on building “tools of mass innovation” designed to allow people to create and innovate on a very large scale. Second, applications and cloud services are allowing the idea of the Internet as a programmable platform to be realized, and they want to make this accessible to more people. Third, they are accomplishing all of this by building the Docker stack with open standards, open infrastructure, and a development platform with commercial products on top of the stack.

  • How to benchmark your Linux system

    The Software Center list will also include individual tests. These can be fine to use, but they can be tedious to open and configure manually. Keep your eye out for an entry called Phoronix Test Suite, or PTS for short. The Phoronix Test Suite is a powerful program that can run a single test, or an entire battery. PTS offers some built-in suites (collection of tests), or you can design your own suite. When tests are completed, you can choose to upload the test results to, where other users can see your results and even run the exact same tests on their PC.

  • Google’s Open Source Report Card Highlights Game-Changing Contributions

    Ask people about Google’s relationship to open source, and many of them will point to Android and Chrome OS — both very successful operating systems and both based on Linux. Android, in particular, remains one of the biggest home runs in open source history. But, as Josh Simmons from Google’s Open Source Programs Office will tell you, Google also contributes a slew of useful open source tools and programs to the community each year. Now, Google has issued its very first “Open Source Report Card,” as announced by Simmons on the Google Open Source Blog.

    "We're sharing our first Open Source Report Card, highlighting our most popular projects, sharing a few statistics and detailing some of the projects we've released in 2016. We've open sourced over 20 million lines of code to date and you can find a listing of some of our best known project releases on our website," said Simmons.

  • Nino Vranešič: Open Source Advocate and Mozilla Rep in Slovenia

    “My name is Nino Vranešič and I am connecting IT and Society,” is what Nino says about himself on LinkedIn. The video is a little hard to understand in places due to language differences and (we think) a slow or low-bandwidth connection between the U.S.-based Zoom servers and Eastern Europe, a problem that crops up now and then in video conversation and VOIP phone calls with people in that part of the world, no matter what service you choose. But Vranešič is worth a little extra effort to hear, because it’s great to learn that open source is being used in lots of government agencies, not only in Slovenia but all over Europe. And aside from this, Vranešič himself is a tres cool dude who is an ardent open source volunteer (“Mozilla Rep” is an unpaid volunteer position), and I hope I have a chance to meet him F2F next time he comes to a conference in Florida — and maybe you’ll have a chance to meet him if he comes to a conference near you.

  • MySQL and database programming for beginners

  • Nadella's trust talk is just so much hot air

    Microsoft chief executive Satya Nadella appears to have an incredibly short memory. Else he would be the last person who talks about trust being the most pressing issue in tech in our times.

    Over the last year, we have been treated to a variety of cheap tricks by Microsoft, attempting to hoodwink Windows users left, right and centre in order to get them to upgrade to Windows 10. After that, talking about trust sounds odd. Very odd.

    Microsoft does not have the best reputation among tech companies. It is known for predatory practices, for being convicted as a monopolist, and in recent times has been trying to cultivate a softer image as a company that is not as rapacious as it once was.

    That has, in large measure, come about as its influence and rank in the world of computing have both slipped, with other companies like Apple, Facebook and Google coming to dominate.

    DragonFlyBSD is now defaulting to LibreSSL throughout its operating system stack and is planning to completely remove OpenSSL in the near future.

  • Ranking the Web With Radical Transparency

    Ranking every URL on the web in a transparent and reproducible way is a core concept of the Common Search project, says Sylvain Zimmer, who will be speaking at the upcoming Apache: Big Data Europe conference in Seville, Spain.

    The web has become a critical resource for humanity, and search engines are its arbiters, Zimmer says. However, the only search engines currently available are for-profit entities, so the Common Search project is creating a nonprofit engine that is open, transparent, and independent.

    We spoke with Zimmer, who founded Jamendo, dotConferences, and Common Search, to learn more about why nonprofit search engines are important, why Apache Spark is such a great match for the job, and some of the challenges the project faces.

  • Why Perl is not use for new development , most of time use for maintenance and support projects ?

    There has been a tendency amongst some companies to play a “wait and see” attitude towards Perl, but the Perl market appears to have stabilized in the past couple of years and more companies appear to be returning to Perl. As one of our clients explained to me when I asked why they chose Perl “We’re tired of being bitten by hype.”

  • Celebrating 12 years of Ubuntu

    Founder Mark Shuttleworth announced the first public release of Ubuntu – version 4.10, or “Warty Warthog” – on Oct. 20, 2004. The idea behind what would become the most recognizable and widely used Linux distributions ever was simple – create a Linux operating system that anybody could use. Here’s a look back at Ubuntu’s history.

  • Happy 12th Birthday, Ubuntu!

    Yup, it’s twelve years to the day since Mark Shuttleworth sat down to tap out the first Ubuntu release announcement and herald in an era of “Linux for human beings”.

  • A Slice of Ubuntu

    The de facto standard for Raspberry Pi operating systems is Raspbian–a Debian based distribution specifically for the diminutive computer. Of course, you have multiple choices and there might not be one best choice for every situation. It did catch our eye, however, that the RaspEX project released a workable Ubunutu 16.10 release for the Raspberry Pi 2 and 3.

    RaspEX is a full Linux Desktop system with LXDE (a lightweight desktop environment) and many other useful programs. Firefox, Samba, and VNC4Server are present. You can use the Ubuntu repositories to install anything else you want. The system uses kernel 4.4.21. You can see a review of a much older version of RaspEX in the video below.

  • Live kernel patching from Canonical now available for Ubuntu 16.04 LTS

    We are delighted to announce the availability of a new service for Ubuntu which any user can enable on their current installations – the Canonical Livepatch Service.

    This new live kernel patching service can be used on any Ubuntu 16.04 LTS system (using the generic Linux 4.4 kernel) to minimise unplanned downtime and maintain the highest levels of security.

  • How to enable free 'Canonical Livepatch Service' for Linux kernel live-patching on Ubuntu

    Linux 4.0 introduced a wonderful feature for those that need insane up-time -- the ability to patch the kernel without rebooting the machine. While this is vital for servers, it can be beneficial to workstation users too. Believe it or not, some home users covet long up-time simply for fun -- bragging rights, and such.

    If you are an Ubuntu 16.04 LTS user (with generic Linux kernel 4.4) and you want to take advantage of this exciting feature, I have good news -- it is now conveniently available for free! Unfortunately, this all-new Canonical Livepatch Service does have a catch -- it is limited to three machines per user. Of course, home users can register as many email addresses as they want, so it is easy to get more if needed. Businesses can pay for additional machines through Ubuntu Advantage. Want to give it a go? Read on.

    "Since the release of the Linux 4.0 kernel about 18 months ago, users have been able to patch and update their kernel packages without rebooting. However, until now, no other Linux distribution has offered this feature for free to their users. That changes today with the release of the Canonical Livepatch Service", says Tom Callway, Director of Cloud Marketing, Canonical.

  • KernelCare Is Another Alternative To Canonical's Ubuntu Live Kernel Patching

    Earlier this week Canonical announced their Kernel Livepatching Service for Ubuntu 16.04 LTS users. Canonical's service is free for under three systems while another alternative for Ubuntu Linux users interested in a commercial service is CloudLinux's KernelCare.

    The folks from CloudLinux wrote in to remind us of their kernel patching solution, which they've been offering since 2014 and believe is a superior solution to Canonical's service. KernelCare isn't limited to just Ubuntu 16.04 but also works with Ubuntu 14.04 and other distributions such as CentOS/RHEL, Debian, and other enterprise Linux distributions.

  • Easy, Automated Benchmarking On Linux With PTS

    It's easy to run benchmarks on Linux as well as Solaris, BSD, and other operating systems, using our own Phoronix Test Suite open-source benchmarking software.

    For those that haven't had the opportunity to play with the Phoronix Test Suite for Linux benchmarking, it's really easy to get started. Aside from the official documentation, which is admittedly limited due to time/resource constraints, there are a few independent guides, Wiki pages, and other resources out there to get started.

  • MPV 0.21 Player Adds CUDA, Better Raspberry Pi Support

    MPV Player 0.21 is now available as the latest version of this popular fork of MPlayer/MPlayer2.

    MPV 0.21 adds support for CUDA and NVDEC (NVIDIA Decode) as an alternative to VDPAU. The NVIDIA decode support using CUDA was added to make up for VDPAU's current lack of HEVC Main 10 profile support. Those unfamiliar with NVDEC can see NVIDIA's documentation.

  • MPV 0.21.0 Media Player Adds Nvidia CUDA Support, Raspberry Pi Hardware Decoding

    Today, October 20, 2016, MPV developer Martin Herkt proudly announced the release of another maintenance update of the very popular MPV open-source and cross-platform media player software based on MPlayer.

    Looking at the release notes, which we've also attached at the end of the story for your reading pleasure, MPV 0.21.0 is a major update that adds a large amount of new features, options and commands, but also addresses dozens of bugs reported by users since the MPV 0.20.0 release, and introduces other minor enhancements.

    Among the most important new features, we can mention the ability to allow profile forward-references in the default profile, as well as support for Nvidia CUDA and cuvid/NvDecode, which appears to be a welcome addition to GNU/Linux distributions where HEVC Main 10 support is missing.

  • Intel Turbo Boost Max 3.0 Patches Updated For Linux 4.9

    Intel has updated its currently out-of-tree Turbo Boost Max Technology 3.0 patches for compatibility against the Linux 4.9-rc1 kernel plus made other improvements to the code.

    These patches have been worked on the past few months after Intel PR initially claimed no TBM 3.0 Linux support. The patches have gone through several public revisions but sadly didn't make it for integration into the mainline Linux 4.9 kernel.

  • Linux 4.9 Is Showing A Performance Boost On More Systems

    Earlier this week I posted some benchmarks of a Core i7 6800K Broadwell-E system seeing performance boosts under Linux 4.9 and it turns out it's looking more widespread than just affecting a niche system or two. When testing a more traditional Intel Haswell desktop, Linux 4.9 Git is seeing more wins over Linux 4.8 and 4.7 kernels.

    Following that earlier 4.9 Git benchmarking I set out to do a fairly large Linux kernel comparison on a Haswell system to go back three or so years worth of kernel releases. That big kernel comparison will be finished up and posted in the days ahead, but already from this Core i7 4790K Devil's Canyon system I am seeing some performance improvements with 4.9 Git to share over 4.7.0 and 4.8.0 stock kernels...

Patten: How to exorcise Windows from your old computer

Filed under

You may have heard of Linux (also known as GNU/Linux), but only as something that hackers use. It has a reputation for being unwieldy and hard. That reputation is deserved … sometimes.

But anyone can learn it. And if it’s good enough for Barbie, it should be good enough for you.

The best part: It’s free, free, free.

Linux is actually a kind of operating system, just as a mammal is a kind of animal. Linux systems are all similar or identical at the core (also known as the kernel). But they come in a lot of varieties, or distros. (Fun fact: Much of the Android operating system is based on Linux.)

The hard part about Linux isn’t learning. It’s choosing.

Dirty Cow, Ubuntu @ 12, Save a Penguin

Filed under

Dirty Cow is a local privilege vulnerability that can allow one to gain root access. Specifically, "race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system." Linus signed off and pushed the patch to git a few days ago and distributions are currently updating their products. This is considered a critical bug and users are encouraged to update as soon as possible because researchers have found code in the wild to exploit it. Worse still, the exploit leaves little or no trace of being compromised. So, keep an eye on your update applets or security advisories over the next few days. Since this bug has been in existence for so long, Kees Cook had to revise his critical bug lifetime average from 3.3 to 5.2 years, while the overall average for all bugs increased only slightly.

  • Linux Kernels 4.8.3, 4.7.9 & 4.4.26 LTS Out to Patch "Dirty COW" Security Flaw

    Today, October 20, 2016, Linux kernel maintainer Greg Kroah-Hartman announced three new maintenance updates for the Linux 4.8, 4.7, and 4.4 LTS kernel series, patching a major security vulnerability.

    Known as "Dirty COW," the Linux kernel vulnerability documented at CVE-2016-5195 is, in fact, a nasty bug that could have allowed local users to write to any file they can read. The worst part is that the security flaw was present in various Linux kernel builds since at least the Linux 2.6.x series, which reached end of life in February this year.

    Feral Interactive is well known for bringing AAA titles to the Linux and Mac gaming world, and after porting the Tomb Raider 2013 reboot last year to our beloved platforms, which continue to get more fans by the day, now the UK-based video games publisher delights us with the superb Mad Max title developed by Avalanche Studios and published by Warner Bros.

  • Mad Max Launches For Linux

    Feral Interactive's port of Mad Max to Linux (and macOS) is now officially out and can be found on Steam.

    Feral announced their Mad Max port at the beginning of October while today it's ready to ship. As mentioned in that original article, the Linux system requirements are fairly stiff with only listing NVIDIA hardware under Linux and the minimum being a GTX 660 while the recommendation is at least a GTX 970.

  • Mad Max Appears To Work Fine With RadeonSI Gallium3D

    This morning's release of the Mad Max game for Linux lists only NVIDIA graphics as supported, but it does turn out at least for newer AMD GPUs using the RadeonSI Gallium3D driver things should work -- well, assuming you are using the latest open-source driver code.

  • Mad Max released for Linux, port report and review available

    Mad Max is the latest Linux port from Feral Interactive, probably one of the titles I have been most excited about so hopefully it lives up to the promise.

    It has only been a few weeks since Feral Interactive released Dawn of War II, Chaos Rising and Retribution on Linux, and now we have a real whopper with Mad Max.

    Something Linux lacks is a reasonable amount of high quality open-world story-based games. We started getting a few with Borderlands 2 and Shadow of Mordor, but another top quality game like this is a must for us to keep the interest up.

While the first use for it in the live demo is innocuous, the fact that this is even possible points once again to possible holes in the Playstation’s security.
