  • Not your BASIC web experience: Creative for Command Line Heroes Season 3 Episode 2

    Last week, we introduced this series with an overview of Command Line Heroes’ artwork. We hope you enjoyed reading about the details in the images for our first episode of season 3 about Python. Now, we’ll briefly cover how our web designers work to bring that artwork to you in its many forms—and we uncover the secrets of Episode 2: Learning the BASICs.

    Are there considerations beyond the initial design to take into account when putting the artwork online?
    Rachel Ertel, UX Lead: Considerations outside of the initial visual design are largely based on user experience. These include making sure the page’s load time is quick, to thinking through the way that the user would interact with copy, graphics, and actionable links. We want to make sure that the user comes to the right information at the right time, and that the process of getting where they want to go requires minimum effort and provides maximum reward.

  • Enhancing availability of SAP deployments with Red Hat Enterprise Linux 7 for SAP Solutions

    In August 2019, we announced the general availability of Red Hat Enterprise Linux (RHEL) 7.7, the latest update to the stable and production-ready RHEL 7 platform. RHEL 7 helps customers meet the modern datacenter demands as well as the next-generation IT requirements of existing and new SAP workloads. On top of that, RHEL 7 for SAP Solutions includes additional capabilities to support SAP Applications across the hybrid cloud, from bare-metal servers to public cloud instances, all on a standard, flexible and scalable operating system platform.

    Both RHEL 7.7 and RHEL 7.6 for SAP Solutions bring new features and enhancements1 to bear that can help streamline operations through improved availability and reduced operating costs. RHEL 7.6 for SAP Solutions is validated and supported for use with SAP HANA on Intel x86_64 and IBM Power 8. Corresponding validation for SAP HANA on RHEL 7.7 is planned. Other SAP applications and database products, like SAP NetWeaver or SAP ASE may adopt and benefit from RHEL 7.7 features right away. Please consult SAP Note 2369910 and 2235581 for the latest information about validated releases and support by SAP.

  • Advanced Ansible variables in Satellite

    Satellite 6.6 beta was released recently, and contains a number of improvements related to Ansible variables. Ansible variables can be used to customize the behavior of Ansible roles. For example, an Ansible role could be configured to install whatever package is specified in an Ansible variable. From Satellite, we can set the value of the Ansible variable so that the package we want is installed by the role.

    Satellite 6.4 introduced the ability to run Ansible roles on Satellite clients, and allowed for parameters to be defined that could be accessed from within the Ansible roles as variables. However, there were a couple limitations to how Ansible variables were supported in Satellite: only string variables were supported, and the Satellite administrator had to review the Ansible role to discover the variable names that should be defined as parameters within Satellite.

  • Fight for the planet: Building an open platform and open culture at Greenpeace

    Few organizations know this better than Greenpeace. For nearly 50 years, the non-profit has been campaigning for a greener and more peaceful future.

    But in 2015, Greenpeace found itself at a crossroads. To address the climate emergency, Greenpeace knew it needed to shift its organizational culture.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
