  • 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.

Microsoft Claims a Monopoly Over 'Open Source'

Bringing PostgreSQL to Government

  • Crunchy Data, ORock Technologies Form Open Source Cloud Partnership for Federal Clients

    Crunchy Data and ORock Technologies have partnered to offer a database-as-a-service platform by integrating the former's open source database with the latter's managed offering designed to support deployment of containers in multicloud or hybrid computing environments. The partnership aims to implement a PostgreSQL as a service within ORock's Secure Containers as a Service, which is certified for government use under the Federal Risk and Authorization Management Program, Crunchy Data said Tuesday.

  • Crunchy Data and ORock Technologies Partnership Brings Trusted Open Source Cloud Native PostgreSQL to Federal Government

    Crunchy Data and ORock Technologies, Inc. announced a partnership to bring Crunchy PostgreSQL for Kubernetes to ORock’s FedRAMP authorized container application Platform as a Service (PaaS) solution. Through this collaboration, Crunchy Data and ORock will offer PostgreSQL-as-a-Service within ORock’s Secure Containers as a Service with Red Hat OpenShift environment. The combined offering provides a fully managed Database as a Service (DBaaS) solution that enables the deployment of containerized PostgreSQL in hybrid and multi-cloud environments. Crunchy PostgreSQL for Kubernetes has achieved Red Hat OpenShift Operator Certification and provides Red Hat OpenShift users with the ability to provision trusted open source PostgreSQL clusters, elastic workloads, high availability, disaster recovery, and enterprise authentication systems. By integrating with the Red Hat OpenShift platform within ORock’s cloud environments, Crunchy PostgreSQL for Kubernetes leverages the ability of the Red Hat OpenShift Container Platform to unite developers and IT operations on a single FedRAMP-compliant platform to build, deploy, and manage applications consistently across hybrid cloud infrastructures.

Hardware, Science and History

  • An Open Source Toolbox For Studying The Earth

    Fully understanding the planet’s complex ecosystem takes data, and lots of it. Unfortunately, the ability to collect detailed environmental data on a large scale with any sort of accuracy has traditionally been something that only the government or well-funded institutions have been capable of. Building and deploying the sensors necessary to cover large areas or remote locations simply wasn’t something the individual could realistically do. But by leveraging modular hardware and open source software, the FieldKit from [Conservify] hopes to even the scales a bit. With an array of standardized sensors and easy to use software tools for collating and visualizing collected data, the project aims to empower independent environmental monitoring systems that can scale from a handful of nodes up to several hundred.

  • The Early History of Usenet, Part II: Hardware and Economics

    There was a planning meeting for what became Usenet at Duke CS. We knew three things, and three things only: we wanted something that could be used locally for administrative messages, we wanted a networked system, and we would use uucp for intersite communication. This last decision was more or less by default: there were no other possibilities available to us or to most other sites that ran standard Unix. Furthermore, all you needed to run uucp was a single dial-up modem port. (I do not remember who had the initial idea for a networked system, but I think it was Tom Truscott and the late Jim Ellis, both grad students at Duke.) There was a problem with this last option, though: who would do the dialing? The problems were both economic and technical-economic. The latter issue was rooted in the regulatory climate of the time: hardwired modems were quite unusual, and ones that could automatically dial were all but non-existent. (The famous Hayes Smartmodem was still a few years in the future.) The official solution was a leased Bell 801 autodialer and a DEC DN11 peripheral as the interface between the computer and the Bell 801. This was a non-starter for a skunkworks project; it was hard enough to manage one-time purchases like a modem or a DN11, but getting faculty to pay monthly lease costs for the autodialer just wasn't going to happen. Fortunately, Tom and Jim had already solved that problem.

  • UNIX Version 0, Running On A PDP-7, In 2019

    WIth the 50th birthday of the UNIX operating system being in the news of late, there has been a bit of a spotlight shone upon its earliest origins. At the Living Computers museum in Seattle though they’ve gone well beyond a bit of historical inquiry though, because they’ve had UNIX (or should we in this context say unix instead?) version 0 running on a DEC PDP-7 minicomputer. This primordial version on the original hardware is all the more remarkable because unlike its younger siblings very few PDP-7s have survived. The machine running UNIX version 0 belongs to [Fred Yearian], a former Boeing engineer who bought his machine from the company’s surplus channel at the end of the 1970s. He restored it to working order and it sat in his basement for decades, while the vintage computing world labored under the impression that including the museum’s existing machine only four had survived — of which only one worked. [Fred’s] unexpected appearance with a potentially working fifth machine, therefore, came as something of a surprise.
