  • 3 tips for translating your sysadmin experience to hiring managers

    So you need to convince a company that you know your field? I am uniquely qualified to help you out here, as this is something I have some hands-on experience with. As you may have read in my article, A sysadmin's tale, my first real industry experience came from Uncle Sam. I was always technically inclined but had never worked with technology professionally. I didn't get a college degree, and I hadn't yet attended a technical school. DD214 in hand, I found myself in a bit of a pickle. How do I show potential employers that I know technology?

    At the very least, I need them to understand that I can learn and apply myself. I was unemployed for eleven months and had a lot of time to figure this out. I'll walk you through my experience in hopes that you can better express yourself while chasing that new technical position.

  • Announcing OpenShift Serverless 1.5.0 Tech Preview – A sneak peak of our GA

    I am sure many of you are as excited as we about cloud native development, and one of the hot topics in the space is Serverless. With that in mind let’s talk about our most recent release of OpenShift Serverless that includes a number of features and functionalities that definitely improve the developer experience in Kubernetes and really enable many interesting application patterns and workloads.

    For the uninitiated, OpenShift Serverless is based on the open source project Knative and helps developers deploy and run almost any containerized workload as a serverless workload. Applications can scale up or down (to zero) or react to and consume events without lock-in concerns. The Serverless user experience can be integrated with other OpenShift services, such as OpenShift Pipelines, Monitoring and Metering.

  • Red Hat Ansible Certified Content for IBM Z now available for developers

    The entire IBM Z platform is rapidly evolving, with major advances coming across Linux on Z, LinuxONE, and z/OS. Hybrid multicloud demands consistency and agility from all of these platforms. Validation of dozens of open source projects for Linux on Z and LinuxONE has been a boon for developers and DevOps practitioners alike.

    That’s why I’m pleased to announce the availability of the Red Hat Ansible Certified Content for IBM Z, which includes the z/OS Core Collection and is now available on Ansible Galaxy and Ansible Automation Hub as a supported, certified collection by Red Hat.

    This is an important step forward in enabling z/OS to participate in an Ansible-based enterprise automation strategy in exactly the same way that the rest of your environments do. Leveraging Ansible to automate z/OS brings consistency across the hybrid multicloud environments and enables z/OS to transparently participate in your infrastructure.

  • Red Hat Ansible Certified Content for IBM Z: What does it mean for you?

    Today we announced Red Hat Ansible Certified Content for IBM Z. With a vibrant community and roots firmly in open source, Ansible provides automation solutions that span across cloud and on-prem infrastructure. It’s particularly exciting to see all of this come to z/OS.

Deprecating support for the Linux kernel

Running on the Hurd was always a goal for Guix, and supporting multiple kernels is a huge maintenance burden. As such it is expected that the upcoming Guix 1.1 release will be the last version featuring the Linux-Libre kernel. Future versions of Guix System will run exclusively on the Hurd, and we expect to remove Linux-Libre entirely by Guix 2.0. The Linux kernel will still be supported when using Guix on "foreign" distributions, but it will be on a best-effort basis. We hope that other distributions will follow suit and adopt the Hurd in order to increase security and freedom for their users. Read more Also: Guix deprecating support for the Linux kernel
