I asked benny Vasquez, chair of the AlmaLinux OS Foundation, how she would explain the recent Red Hat Enterprise Linux source code controversy to somebody at a family barbecue—somebody who, in other words, might not have followed the latest tech news quite so closely.

"Most of my family barbecues are going to be explaining that Linux is an operating system," Vasquez said. "Then explaining what an operating system is."

It is indeed tricky to explain all the pieces—Red Hat, Red Hat Enterprise Linux, CentOS, CentOS Stream, Fedora, RHEL, Alma, Rocky, upstreams, downstreams, source code, and the GPL—to anyone who isn't familiar with Red Hat's quirky history , and how it progressed to the wide but disparate ecosystem it has today. And, yes, Linux in general. But Vasquez was game to play out my thought experiment.

When CentOS announced in 2020 that it was shutting down its traditional "rebuild" of Red Hat Enterprise Linux (RHEL) to focus on its development build, Stream, CentOS suggested the strategy "removes confusion." Red Hat, which largely controlled CentOS by then, considered it "a natural, inevitable next step."

Last week, the IBM-owned Red Hat continued " furthering the evolution of CentOS Stream " by announcing that CentOS Stream would be "the sole repository for public RHEL-related source code releases," with RHEL's core code otherwise restricted to a customer portal. (RHEL access is free for individual developers and up to 16 servers , but that's largely not what is at issue here).

Red Hat's post was a rich example of burying the lede and a decisive moment for many who follow the tricky balance of Red Hat's open-source commitments and service contract business. Here's what followed.

Virtual Machines are software used to run other operating systems within a pre-installed operating system. This self-contained OS runs as a separate computer that has no relation to the host OS. VirtualBox is an open-source cross-platform software that can help you run multiple guest operating systems on a single computer. In this article, let’s look at how to install VirtualBox 6.1 on Linux, easily.

Why Install VirtualBox?

One of the most important use cases of VirtualBox is its ability to try out/test various operating systems without fiddling with your internal storage. VirtualBox creates a virtual environment that utilizes system resources like RAM and CPU to power the OS inside a container.

For example, if I want to try out and check if the latest Ubuntu release is stable or not, I can use VirtualBox to do it and only then decide if I want to install it or just totally use it in VirtualBox. This not only saves me a lot of time but also makes the process flexible.
