  • The long, slow death of commercial Unix [Ed: Microsoft propagandist Andy Patrizio should also do an article about the death of Windows Server.]

    In the 1990s and well into the 2000s, if you had mission-critical applications that required zero downtime, resiliency, failover and high performance, but didn’t want a mainframe, Unix was your go-to solution.

    If your database, ERP, HR, payroll, accounting, and other line-of-business apps weren’t run on a mainframe, chances are they ran on Unix systems from four dominant vendors: Sun Microsystems, HP, IBM and SGI. Each had its own flavor of Unix and its own custom RISC processor. Servers running an x86 chip were at best used for file and print or maybe low-end departmental servers.

  • What is Server Virtualization: Is It Right For Your Business?

    In the modern world of IT application deployment, server virtualization is a commonly used term. But what exactly is server virtualization and is it right for your business?

    Server virtualization in 2019 is a more complicated and involved topic than it was when the concept first started to become a popular approach nearly two decades ago. However, the core basic concepts and promises remain the same.

  • Transitioning Red Hat SSO to a highly-available hybrid cloud deployment

    About two years ago, Red Hat IT finished migrating our customer-facing authentication system to Red Hat Single Sign-On (Red Hat SSO). As a result, we were quite pleased with the performance and flexibility of the new platform. Due to some architectural decisions that were made in order to optimize for uptime using the technologies at our disposal, we were unable to take full advantage of Red Hat SSO’s robust feature set until now. This article describes how we’re now addressing database and session replication between global sites.

  • Red Hat named to Fortune’s 100 Best Companies to Work For list

    People come to work at Red Hat for our brand, but they stay for the people and the culture. It's integral to our success as an organization. It's what makes the experience of being a Red Hatter and working with other Red Hatters different. And it's what makes us so passionate about our customers’ and Red Hat’s success. In recognition of that, Red Hat has been ranked No. 50 on Fortune Magazine's list of 100 Best Companies to Work For! Hats off--red fedoras, of course--to all Red Hatters!

  • News from Fedora Infrastructure

    One of the first tasks we have achieved is to move as many application we maintain to use CentOS CI for our Continuous Integration pipeline. CentOS CI provides us with a Jenkins instance that is running in an OpenShift cluster, you can have a look at the this instance here.

    Since a good majority of our application are developed in Python, we agreed on using tox to execute our CI tests. Adopting tox on our application allows us to use a really convenient way to configure the CI pipeline in Jenkins. In fact we only needed to create .cico.pipeline file in the application repository with the following.

  • Mirantis to Help Build AT&T's Edge Computing Network for 5G On Open Source

    The two companies hope other telcos will follow AT&T's lead in building their 5G networks on open source software.

  • The Telecom Industry Has Moved to Open Source

    The telecom industry is at the heart of the fourth industrial revolution. Whether it’s connected IoT devices or mobile entertainment, the modern economy runs on the Internet.
    However, the backbone of networking has been running on legacy technologies. Some telecom companies are centuries old, and they have a massive infrastructure that needs to be modernized.
    The great news is that this industry is already at the forefront of emerging technologies. Companies such as AT&T, Verizon, China Mobile, DTK, and others have embraced open source technologies to move faster into the future. And LF Networking is at the heart of this transformation.
    “2018 has been a fantastic year,” said Arpit Joshipura, General Manager of Networking at Linux Foundation, speaking at Open Source Summit in Vancouver last fall. “We have seen a 140-year-old telecom industry move from proprietary and legacy technologies to open source technologies with LF Networking.”

  • Monroe Electronics Releases Completely Redesigned HALO Version 2.0

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.
