Contain yourself: The layman's guide to Docker

Filed under
GNU
Linux
Server

Welcome to the age of containerization, where an ecosystem led by startup Docker is leading IT organizations to ineffable peaks of efficiency, helping them scale their workloads ever-higher, and probably baking them a nice cake to boot (it's my birthday, I have cake on the brain, sue me). Microsoft, Google and Amazon Web Services are all tripping over themselves to make sure prospective customers know that their clouds are the place to be if you want to get the most from Docker.

More File-System Tests Of The Linux 3.18 Kernel

Filed under
Linux

Earlier this week on Phoronix I posted benchmarks indicating potential block/file-system performance regressions using the Linux 3.18 kernel. Since then I've been carrying out more tests looking for any file-system performance problems on other hardware.

The tests earlier this week showed the Flexible I/O Tester (FIO) regressing for EXT4/Btrfs/XFS/F2FS from a OCZ Vertex 3 SATA SSD with Intel Core i7 5960X Haswell-E system. I've been running a few more Linux 3.17 vs. Linux 3.18 Git comparisons looking at the disk performance for other Linux systems:

Linux

With Mint 17.1 Rebecca being days away from release, and Cinnamon 2.4 looking so good, here is an overview of some of the best looking themes which allow you to beautify your desktop.

Most of these are available online, and you can install them from Menu -> Preferences -> Themes. There are also some themes from gnome-look.org, and to install those you need to download the archive and uncompress it inside the ~/.themes folder. I specified the themes which are are from gnome-look.org

V2 Of KDBUS Published For Linux Kernel Review

Filed under
Linux

The second revision to the Linux kernel based D-Bus implementation is now available for review.

Greg Kroah-Hartman on Thursday night posted the "v2" revision of the KDBUS implementation for providing the kernel with a new IPC implementation that resembles the existing user-space D-Bus daemon while adding extra features.

Among the changes in this revision to KDBUS are exposing its control files and other information via a new kdbusfs file-system, KDBUS expects to be mounted to /sys/fs/kdbus, a new KDBUS domain is created for each time kdbusfs is mounted, and various other low-level changes.

More details via the patch-set series. It's not clear yet whether KDBUS will be ready for merging in the Linux 3.19 kernel or will be held off until Linux 3.20 or longer.

GNU
Linux

This is the first home wifi router on the planet that you can go out and purchase that ships only with software that respects your freedom: libreCMC, a distribution of GNU/Linux recently endorsed by the FSF. This is awesome and you should replace your proprietary software-based wireless router at home with one of these! I've personally been using one at home for a few weeks now and I love it. I even made an unboxing video for you so you can see how simple it is to set-up.

The Great Paradox: On Windows 10 and Innovation

Talk about the paradoxes of life! I woke up today and saw this article mentioning "3 cool features" of Windows 10. Of course the are cool. But they are neither "new" nor "Windows features" at all.

The author and I agree on one point: With Windows 10, Windows is becoming more and more like Linux.

SDN in action: Hands-on with Cumulus Linux

Filed under
Linux
Server

The stage is set for SDN (software-defined networking) to change the way we push data through our infrastructures, with the promises of more agile network provisioning and management, as well as more affordable network hardware. But for many, the SDN concept is still amorphous. What does SDN look like in practice?

To shed light on this question, I sat down with a few Dell Networking S6000 switches running Cumulus Linux 2.3. There are many approaches to an SDN solution, but one of the most significant is the advent of white-box switches and à la carte switch firmware. This is the essence of the solution offered by Cumulus Networks.

Linux Mint isn’t chasing touch interfaces, rethinking the way we use the desktop, or enacting any other grand experiment. It’s just a polished, modern Linux desktop system—and that’s why people love it. Linux Mint 17.1 (codenamed “Rebecca”) is on the brink of being released, and it continues the Linux Mint mission of refining the interface we use every day.

Bang & Olufsen’s RPi add-on brings digital life to old speakers

B&O and HiFiBerry have launched an open source, DIY “Beocreate 4” add-on for the Raspberry Pi that turns vintage speakers into digitally amplified, wireless-enabled smart speakers with the help of a 180-Watt 4-channel amplifier, a DSP, and a DAC. Bang & Olufsen has collaborated with HiFiBerry to create the open source, $189 Beocreate 4 channel amplifier kit. The 180 x 140 x 30mm DSP/DAC/amplifier board pairs with your BYO Raspberry Pi 3 with a goal of upcycling vintage passive speakers. Read more

The makers of the Gemini PDA plan to begin shipping the first units of their handheld computer to their crowdfunding campaign backers any day now. And while the folks at Planet Computer have been calling the Gemini PDA a dual OS device (with Android and Linux support) from the get go, it turns out the first units will actually just ship with Android.

Browsers: Mozilla and Iridium

  • Best Web Browser
    When the Firefox team released Quantum in November 2017, they boasted it was "over twice as fast as Firefox from 6 months ago", and Linux Journal readers generally agreed, going as far as to name it their favorite web browser. A direct response to Google Chrome, Firefox Quantum also boasts decreased RAM usage and a more streamlined user interface.
  • Share Exactly What You See On-Screen With Firefox Screenshots
    A “screenshot” is created when you capture what’s on your computer screen, so you can save it as a reference, put it in a document, or send it as an image file for others to see exactly what you see.
  • What Happens when you Contribute, revisited
    I sat down to write a post about my students' experiences this term contributing to open source, and apparently I've written this before (and almost exactly a year ago to the day!) The thing about teaching is that it's cyclic, so you'll have to forgive me as I give a similar lecture here today. I'm teaching two classes on open source development right now, two sections in an introductory course, and another two in a follow-up intermediate course. The students are just starting to get some releases submitted, and I've been going through their blogs, pull requests, videos (apparently this generation likes making videos, which is something new for me), tweets, and the like. I learn a lot from my students, and I wanted to share some of what I'm seeing.
