  • Why Learn-by-Doing Matters

    I founded Linux Academy over seven years ago to help people learn by doing. The idea was and continues to be that learning by doing helps us learn faster and retain more information. With the pace of change in our multi-cloud world, learning quickly with a higher retention rate has become more important in our everyday lives. Over the years, we at Linux Academy have taken on the responsibility to empower our students with the ability to learn by doing very seriously. It’s in our DNA.

    But while Linux Academy is just seven years old, learning by doing is a bit older. John Dewey coined the term Learn by Doing and its philosophy in the early 20th century. His initial applications of experiential learning were in childhood development, but he wrote some pretty inspirational things that have much broader implications for multicloud training for Linux Academy.

  • Process ID Limiting for Stability Improvements in Kubernetes 1.14

    Have you ever seen someone take more than their fair share of the cookies? The one person who reaches in and grabs a half dozen fresh baked chocolate chip chunk morsels and skitters off like Cookie Monster exclaiming “Om nom nom nom.”

    In some rare workloads, a similar occurrence was taking place inside Kubernetes clusters. With each Pod and Node, there comes a finite number of possible process IDs (PIDs) for all applications to share. While it is rare for any one process or pod to reach in and grab all the PIDs, some users were experiencing resource starvation due to this type of behavior. So in Kubernetes 1.14, we introduced an enhancement to mitigate the risk of a single pod monopolizing all of the PIDs available.

  • SUSECON 2019 – What a great experience!

    For those of you who made it to SUSECON 2019 in Nashville, I hope you had as great a time as I did. If you were not able to make it please consider coming next year. Without a doubt, this was one of the best events I have ever attended. And I am not just saying that because I work for SUSE.

  • The World has Changed Since Tiger Woods First Won the Masters!

    “The open source movement is in some ways the spiritual core of the Internet, encompassing much of the hardware, software, and protocols that make up the global communications infrastructure — as well as championing openness, transparency, and the power of collaborative development.”[4]

    That’s what SUSE is all about. We pride ourselves on being a truly open, open source company. We are at the forefront of delivering open source software and solutions that are increasingly essential in this new interconnected world.

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.
