Wednesday 5th of June 2019 07:00:00 AM

GraphQL is one of the biggest buzzwords in software tech today. But what is it actually? Is it a query language like SQL? An execution engine like the JVM? A specification like XML?

Kubernetes is a dump truck: Here's why

Tuesday 4th of June 2019 01:47:00 PM

As we approach Kubernetes anniversary on Friday, June 7 this week let's start with this.

Dump trucks are elegant. Seriously, stay with me for a minute. They solve a wide array of technical problems in an elegant way. They can move dirt, gravel, rocks, coal, construction material, or road barricades. They can even pull trailers with other pieces of heavy equipment on them. You can load a dump truck with five tons of dirt and drive across the country with it. For a nerd like me, that's elegance.

Tuesday 4th of June 2019 07:00:00 AM

A community will always surprise you.

That's not an easy statement for someone like me to digest. I'm not one for surprises. I revel in predictability. I thrive on consistency.

Create a CentOS homelab in an hour

Tuesday 4th of June 2019 07:00:00 AM

When working on new Linux skills (or, as I was, studying for a Linux certification), it is helpful to have a few virtual machines (VMs) available on your laptop so you can do some learning on the go.

How many browser tabs do you usually have open?

Monday 3rd of June 2019 07:02:00 AM

Here's a potentially loaded question: How many browser tabs do you usually have open at one time? Do you have multiple windows, each with multiple tabs? Or are you a minimalist, and only have a couple of tabs open at once. Another option is to move a 20-tabbed browser window to a different monitor so that it is out of the way while working on a particular task.

How to stream music with GNOME Internet Radio

Monday 3rd of June 2019 07:00:00 AM

Internet radio is a great way to listen to stations from all over the world. Like many developers, I like to turn on a station as I code. You can listen to internet radio with a media player for the terminal like MPlayer or mpv, which is what I use to listen via the Linux command line.

When Diverse Network ASICs Meet A Unifying Operating System

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” Read more

Server: Kubernetes/OpenShift, OpenStack, and Red Hat's Ansible

  • 9 steps to awesome with Kubernetes/OpenShift presented by Burr Sutter

    Burr Sutter gave a terrific talk in India in July, where he laid out the terms, systems and processes needed to setup Kubernetes for developers. This is an introductory presentation, which may be useful for your larger community of Kubernetes users once you’ve already setup User Provisioned Infrastructure (UPI) in Red Hat OpenShift for them, though it does go into the deeper details of actually running the a cluster. To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps.

  • Weaveworks Named a Top Kubernetes Contributor

    But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security).

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with?
