    Immediately after announcing the release of Linux kernel 4.7.6, Greg Kroah-Hartman proudly informed the community about the general availability of the Linux 4.4.23 LTS kernel.

    The Linux 4.4 kernel is a long-term supported branch, the latest and most advanced one, used in many stable and reliable GNU/Linux operating systems, including Ubuntu 16.04 LTS (Xenial Xerus) and Alpine Linux 3.4. Therefore, it is imperative for it to receive regular updates that bring fixes to the most important issues, as well as other general improvements.

  • From NFS to LizardFS

    If you’ve been following me for a while, you’ll know that we started our data servers out using NFS on ext4 mirrored over DRBD, hit some load problems, switched to btrfs, hit load problems again, tried a hacky workaround, ran into problems, dropped DRBD for glusterfs, had a major disaster, switched back to NFS on ext4 mirrored over DRBD, hit more load problems, and finally dropped DRBD for ZFS.

  • BUS1, The Successor To KDBUS, Formally Unveiled -- Aiming For Mainline Linux Kernel

    BUS1 has been in development as an in-kernel IPC mechanism building off the failed KDBUS project. An "RFC" will soon be sent out to Linux kernel developers about BUS1 and the subject will be discussed at next month's Kernel Summit.

    David Herrmann, one of the BUS1 developers, presented at this week's systemd.conf conference about the new capability-based IPC for Linux. He talked about how BUS1 is superior to KDBUS, how BUS1 is similar to Android's Binder, Chrome's Mojo, Solaris' Doors, and other common IPC implementations.

  • A New Wireless Daemon Is In Development To Potentially Replace wpa_supplicant

    In addition to the BUS1 presentation, also exciting from the systemd.conf 2016 conference is a thorough walkthrough of a new wireless daemon for Linux being developed by Intel's Open-Source Technology Center.

    Intel has been developing a new wireless daemon for Linux to potentially replace wpa_supplicant. This new daemon isn't yet public but the code repositories for it will be opened up in the next few weeks. This new daemon has improvements around persistency, WiFi management, reduced abstractions for different operating systems and legacy interfaces, and changes to operation. This daemon is designed to be very lightweight and work well for embedded Linux use-cases especially, including IoT applications.

How to Effectively and Efficiently Edit Configuration Files in Linux

Filed under
Linux
HowTos

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss.

Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient.

Why Good Linux Sysadmins Use Markdown

Filed under
Linux

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting.

The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better.

Licensing resource series: Free GNU/Linux distributions & GNU Bucks

Filed under
GNU
Linux

When Richard Stallman set out to create the GNU Project, the goal was to create a fully free operating system. Over 33 years later, it is now possible for users to have a computer that runs only free software. But even if all the software is available, putting it all together yourself, or finding a distribution that comes with only free software, would be quite the task. That is why we provide a list of Free GNU/Linux distributions.

Each distro on the list is commited to only distributing free software. With many to choose from, you can find a distro that meets your needs while respecting your freedom.

But with so much software making up an entire operating system, how is it possible to make sure that nothing nasty sneaks into the distro? That's where you, and GNU Bucks come in.

    Last week's DDOS takedown of security guru Brian Krebs' website made history on several levels. For one, it was the largest such reported attack ever, with unwanted traffic to the site hitting levels of 620 Gbps, more than double the previous record set back in 2013, and signalling that the terabyte threshold will certainly be crossed soon. It also relied primarily on compromised Internet of Things devices.

A Phoronix reader has setup a Fedora Copr repository that is building Intel's Vulkan driver from Mesa Git plus the RADV Radeon Vulkan driver re-based from its source (David Airlie's semi-interesting GitHub branch). Fedora COPR, for the uninformed, is the distribution's equivalent to Ubuntu PPA repositories.
  • Meeting users, lots of users
    Every year, I introduce Fedora to new students at Brno Technical University. There are approx. 500 of them and a sizable amount of them then installs Fedora. We also organize a sort of installfest one week after the presentation where anyone who has had any difficulties with Fedora can come and ask for help. It’s a great opportunity to observe what things new users struggle with the most. Especially when you have such a high number of new users. What are my observations this year?

  • Yahoo open-sources a deep learning model for classifying pornographic images
    Yahoo today announced its latest open-source release: a model that can figure out if images are specifically pornographic in nature. The system uses a type of artificial intelligence called deep learning, which involves training artificial neural networks on lots of data (like dirty images) and getting them to make inferences about new data. The model that’s now available on GitHub under a BSD 2-Clause license comes pre-trained, so users only have to fine-tune it if they so choose. The model works with the widely used Caffe open source deep learning framework. The team trained the model using its now open source CaffeOnSpark system. The new model could be interesting to look at for developers maintaining applications like Instagram and Pinterest that are keen to minimize smut. Search engine operators like Google and Microsoft might also want to check out what’s under the hood here. “To the best of our knowledge, there is no open source model or algorithm for identifying NSFW images,” Yahoo research engineer Jay Mahadeokar and senior director of product management Gerry Pesavento wrote in a blog post.
