  • [IBM fluff] Help build the future of education

    I know how fortunate I was to have had great access to education and technology from an early age. My mother was a K-6 teacher and later an administrator for the early childhood learning program, Head Start. My father was an electrical engineer (I followed in his footsteps) and later studied nights to become a college professor, ensuring that my two sisters and I had the opportunity to earn our college degrees without cost. Tagging along with them growing up, education was such a big part of our lives, and I got to spend a great deal of time in learning environments beyond my own schools.

  • Linux 5.15 Addressing Scalability Issue That Caused Huge IBM Servers 30+ Minutes To Boot

    Very large IBM mainframes/servers were taking 30+ minutes to boot the Linux kernel... No, just not for POST'ing the system with memory training and the like, but for loading Linux. Fortunately, with the Linux 5.15 kernel there is a set of scalability enhancements to allow these large IBM systems to be able to boot in around five minutes.

    With the driver core changes for Linux 5.15 is a set of patches working on enhancing the performance of Kernfs for functionality used around pseudo file-systems like sysfs. Leading to this Kernfs locking and concurrency improvements were engineers finding that large IBM Power mainframe systems with "several hundred CPUs and 64TB of RAM" were taking 30+ minutes to just boot the Linux kernel. Extra kernel parameters were also needed to avoid the kernel timing out on boot.

  • Using RHEL’s Lightweight Kiosk Mode in Edge Deployments

    Less is more. This is often the perspective behind requests we see that involve the words "light weight." I’ve come to loosely translate this to mean, "install and/or run only the applications I care about with no fluff."

    The motivation can be any number of problems around decreasing the installed footprint for security purposes, maximizing system resources, or perceived stability improvements from using less software (less to go wrong).

    Each of these points have their merit in any environment, but they are especially relevant in edge computing which is why we have a new means of deploying RHEL that helps tackle these concerns.

  • Open patients and open researchers: Bridging the next decade of transparency in healthcare

    Today we’re launching the next video in our Open Source Stories "Common Connections" series, "Common Connections: Healthcare Made Human." The series features scholars, CEOs, educators, and engineers coming together to find the common threads in their work, and exploring the potential for future open source innovation and building unexpected connections.

    "Common Connections: Healthcare Made Human" brings together Dr. Tom Delbanco, co-founder of OpenNotes, Liz Salmi, senior strategist of Research Dissemination for OpenNotes and Jan Walker, co-founder of OpenNotes who first met after appearing together in our film, "The Open Patient: Healing through sharing." Five years after their initial meeting, the three are now working together to make their vision for greater transparency in healthcare a reality.

    We’ve invited the OpenNotes team to share their recollections on their initial meeting and the impact it has made on their cause.

    Red Hat's Products and Technologies organization is doing game-changing work in the IT industry. In showcasing the unique stories of Red Hatters around the world, it's clear that there's no one path to finding success at Red Hat. For each of us, it's about open collaboration and building something together.

  • Red Hat CodeReady Containers 1.31.2 makes the leap | Red Hat Developer

    Red Hat CodeReady Containers supports local development and testing on a Red Hat OpenShift cluster. We recently released CodeReady Containers 1.31.2, which is the first version based on the major OpenShift 4.8 release. The CodeReady Containers team doesn't publicly report our advances on a regular basis, so this article is a good opportunity to learn about the biggest changes to CodeReady Containers during the past several months.

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 go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
