Canonical/Ubuntu: Design and Web, Ubuntu Weekly Newsletter and Introduction to MicroK8s

  • Design and Web team summary – 17 September 2019

    This was a fairly busy two weeks for the Web & design team at Canonical. Here are some of the highlights of our completed work.

  • Ubuntu Weekly Newsletter Issue 596

    Welcome to the Ubuntu Weekly Newsletter, Issue 596 for the week of September 8 – 14, 2019. The full version of this issue is available here.

  • Introduction to MicroK8s – Part 1/2

    Every developer, systems admin and tech enthusiast is interested in learning Kubernetes. Kubernetes is a complex container orchestration tool that can be overwhelming for beginners. Kubernetes has been the buzzword in the tech industry and for good reason. If you’re itching to get started with Kubernetes and not looking forward to the complexities involved, this first blog of a series is for you. We’ll walk you through getting up and running in a jiffy with a Kubernetes deployment using MicroK8s. The following blogs will do a deeper dive into add-ons and usage.

Linux 5.4 Developments Explained

  • Linux 5.4 Adds Qualcomm Snapdragon 855, Supports Some Newer ARM Laptops

    The ARM SoC platform and driver changes landed on Monday during the first full day of the Linux 5.4 merge window. There is some exciting ARM hardware support improvements for this kernel while doing away with some older platforms.

  • Linux 5.4 Continues Sound Open Firmware, Improvements For AMD/NVIDIA HDMI Audio

    Linux 5.4 will sound better. Well, at least provide audio support on more hardware with this next kernel release thanks to the latest batch of open-source sound improvements.

  • Linux 5.4 Dropping Support For The Itanium IA64-Powered SGI Altix

    With Intel having ended the Itanium CPU family at the beginning of the year and much of the open-source/Linux software support for IA64 already having been on the decline for years, the Linux kernel is beginning to remove more IA64 bits. This comes following IA64 support being deprecated for GCC 10 and likely removed for the GCC 11 release in 2021. Once that IA64 support is gone from GCC, chances are the Linux kernel support for IA64 will be dropped entirely since there isn't any other compiler capable of building the Linux kernel and supporting IA64 as well as GCC.

  • Linux 5.4 Scheduler Changes Bring Better AMD EPYC Load Balancing, Other Optimizations

    The Linux 5.4 scheduler changes are fairly exciting on multiple fronts. One of the Linux 5.4 scheduler changes we have been looking forward to is improved EPYC load balancing and that work is indeed part of today's pull request. The better EPYC load balancing is a scheduler topology improvement to better deal with load balancing across NUMA nodes on EPYC 2P servers. I'll be running some benchmarks of this EPYC-specific scheduler change in the days ahead.

Funtoo Linux 1.4 Released

Drobbins has announced the new release of Funtoo Linux 1.4 on Sep 11, 2019.

This is the fourth release of the Funtoo Linux 1.x series, which may be the last update of this release, as the developer said he would start developing 2.0 a month later. Read more

10 more essential Linux commands you need to know

When you practice commands that can be harmful to a production system, have a virtual machine running somewhere that you can torture and restore should something go wrong. For some reason, people generally frown on having to repair or reinstall production systems because someone practiced a new command that went awry. Plus, it's cool to show up one day armed with new sysadmin skills to impress (school) your coworkers. Remember to say, "Watch this," to be sure they're paying attention before you hit the Enter key so it's more dramatic and awe-inspiring. Read more
