  • How we brought JavaScript to life for Command Line Heroes

    Animators within Red Hat?s Open Studio help bring Command Line Heroes? artwork more to life. All throughout Season 3, they?ve added movement to our episode pages and created eye-catching trailers for social and Red Hat?s YouTube channel. This post highlights their important contributions to the Command Line Heroes? creative process by looking at their work for Episode 3 of Season 4: Creating JavaScript. Also, designer Karen Crowson talks about the easter eggs in that episode?s artwork.

  • Red Hat Ceph Storage RGW deployment strategies and sizing guidance

    Starting in Red Hat Ceph Storage 3.0, Red Hat added support for Containerized Storage Daemons (CSD) which allows the software-defined storage components (Ceph MON, OSD, MGR, RGW, etc) to run within containers. CSD avoids the need to have dedicated nodes for storage services thus reducing both CAPEX and OPEX by co-located storage containerized daemons.

    Ceph-Ansible provides the required mechanism to put resource fencing to each storage container which is useful for running multiple storage daemon containers on one physical node. In this blog post, we will cover strategies to deploy RGW containers and their resource sizing guidance. Before we dive into the performance, let's understand what are the different ways to deploy RGW.

  • OpenShift 4.2: New YAML Editor

    Through our built-in YAML editor, users can create and edit resources right in the Red Hat OpenShift Web Console UI. In the latest release, we’ve upgraded our editor to include language server support.

    What is language server support?

    The language server support feature uses the OpenAPI schema from Kubernetes to provide content assist inside the YAML editor based on the type of resource you are editing. More specifically, the language server support offers the following capabilities:

    Improved YAML validation: The new editor provides feedback in context, directing you to the exact line and position that requires attention.
    Document outlining: Document outlines offer a quick way to navigate your code.
    Auto completion: While in the editor, language server support will provide you with valid configuration information as you type, allowing you to edit faster.
    Hover support: Hovering over a property will show a description of the associated schema.
    Advanced formatting: Format your YAML.

RISC-V, the Linux of the chip world, is starting to produce technological breakthroughs

A decade ago, an idea was born in a laboratory at the University of California at Berkeley to create a lingua franca for computer chips, a set of instructions that would be used by all chipmakers and owned by none. It wasn't supposed to be an impressive new technology, it was merely supposed to get the industry on the same page, to simplify chip-making in order to move things forward. Read more
