Up until a late 2020 announcement from Red Hat, CentOS Linux had a longstanding reputation as a dependable and enterprise-class Linux distribution. And now, the main purpose of CentOS is shifting. Along with that comes a name change to CentOS Stream. In this article, we'll talk about this change of direction for CentOS, and what it means for the huge community of users and businesses that have relied on the distro for years. We'll also see what's next, as many users are left scrambling for a replacement so they can avoid switching to CentOS Stream.

The main motivation behind the creation of AlmaLinux was to be a viable replacement for CentOS Linux at the time of its shift from an enterprise-stable operating system to an upstream development branch of RHEL. Now that AlmaLinux is released, it still leaves CentOS users wondering how to switch operating systems. Ideally, this should be done as seamlessly as possible, to prevent downtime, loss of data, etc. In this guide, we'll show you the step by step instructions to migrate from CentOS to AlmaLinux with just a few commands.

As a long term user of Microsoft Windows, Fedora, Ubuntu and Linux Mint, I have seen some of the more intricate tantrums a Windows or Linux operating system can throw. My first Mint 20 installation was in early April 2020, even before Mint 20 was released. I have had the unique opportunity to compare it with Microsoft Windows and Ubuntu 20 for day-to-day work and use, and have made some interesting discoveries. Read on to find out.

Libvirt is a free and open source software which provides API to manage various aspects of virtual machines. On Linux it is commonly used in conjunction with KVM and Qemu. Among other things, libvirt is used to create and manage virtual networks. The default network created when libvirt is used is called “default” and uses NAT (Network Address Translation) and packet forwarding to connect the emulated systems with the “outside” world (both the host system and the internet). In this tutorial we will see how to create a different setup using Bridged networking.

When installing a content management system for your website, it's easy to get lazy and assume that it's going to do all the work for you. A CMS like Joomla certainly does make things more convenient, and lets you publish a polished website very quickly, but that doesn't mean you shouldn't take some extra time to secure it.

In this article we will be perform an installation of the NVIDIA Driver on AlmaLinux. Nvidia driver is needed by your NVIDIA Graphics GPU to function with better performance. To do this we are first going to identify your NVIDIA graphic card, download an appropriate NVIDIA driver , disable the default nouveau driver by modifying the GRUB boot menu and finally install a official NVIDIA driver.

The goal of a relational database normalization is to achieve and improve data integrity and avoid data redundancy so to avoid possible insertion, updation or deletion anomalies. A relational database is normalized by applying a series of rules called normal forms. In this article we will discuss the first three normal forms

Although many operating system are available for the Raspberry Pi, the official one is the Raspberry Pi Os. The operating system is made to run for the arm architecture, and can be easily installed on the SD card which will be used as the main Raspberry Pi storage device. Sometimes we may want to perform some tests or try some applications without having a physical Raspberry Pi machine; in this tutorial we will see how we can create a virtual machine with the Raspberry Pi Os system using Qemu and Kvm (Kernel Virtual Machine).

If you want to run Kali Linux on your system but you already have Windows 10 installed, you have a couple of options. One thing you could do is install Kali Linux in a virtual machine, as we've shown in our tutorials for installing Kali in VMware and installing Kali in VirtualBox.

Vulnerabilities in WordPress can be uncovered by the WPScan utility, which comes installed by default in Kali Linux. It's also a great tool for gathering general reconnaissance information about a website that's running WordPress. Owners of WordPress sites would be wise to try running WPScan against their site, as it may reveal security issues that need patched. It can also reveal more general web server issues, such as directory listings that haven't been turned off inside Apache or NGINX.

On Linux and Unix-based operating systems, pipes are very useful since they are a simple way to achieve IPC (inter-process communication). When we connect two processes in a pipeline, the output of the first one is used as the input of the second one.

xz compression has been rising in popularity because it offers smaller file sizes than gzip and bzip2. You're still likely to see all three on a Linux system, but you may want to start opting for xz if you want smaller file archives. In this guide, we're going to introduce you to xz compression, starting from basic examples to more specific and advanced usage. If you've worked with compressed tar files or gzip compression (files with the .tar.gz extension, for example) in the past, you'll find that xz feels very familiar.

Linux inherently works well for coding and testing software. For developers and programmers, almost any Linux distro will be a good fit. When it comes to picking a distro for developing, the biggest factor is just going to be personal preference. Even so, some distros offer certain features that developers may find particularly helpful for their work.

Regular, when writing a command - both easy and complex ones - one will want to access more detailed information about the command and it’s available options. There is a wealth of information available in the Linux manual pages, and this is provided free of charge, and is available with just a few keystrokes.

CSV is the acronym of “Comma Separated Values”. A csv file is a just plain text document used to represent and exchange tabular data. Each row in a csv file represents an “entity”, and each column represents an attribute of it. Columns are usually separated by a comma but other characters can be used as field separator instead of it. In this tutorial we will see how to read and create csv files using Python and specifically the csv module, which is part of the language standard library.

Whenever we work with textual strings, sooner or later the issue of case comes up. Does a word need to be fully uppercase, fully lowercase, with a capitalized letter at the start of the word or sentence, and so on. An idiom is a natural language expression of a simple programming task. For example, in the sleep 10 command (which will pause the terminal one is working in for ten seconds), the word sleep is a natural language expression of what is a time based coding construct, developed in the Bash GNU coreutils software package.

Oracle Linux and Red Hat Enterprise Linux (RHEL) are well-known Linux distributions, often used in the business world. Each distro has their own pros and cons, differences, and similarities to the other. In this guide, we'll be comparing the two distributions across a few key areas and giving a brief review of both distros. Read on to learn more about Oracle Linux and RHEL and how they compare. By the end of this article, you'll be armed with enough information to choose the best distro for your needs.

When using the Apache web server, .htaccess files (also called “distributed configuration files”) are used to specify configuration on a per-directory basis, or more generally to modify the behavior of the Apache web server without having to access virtual hosts files directly (this is usually impossible for example, on shared hosts). In this tutorial we see how we can establish URL redirections and rewriting rules inside .htaccess files.

Using a screen of a remote computer is often using VNC (Virtual Network Computing), or other remote desktop solutions. These come in both commercial and open source flavors. But how do you go about mirroring, and using, your Android mobile phone to and from your Linux desktop?

Pop!_OS and Ubuntu are both popular Linux distributions, each of which has their pros and cons, differences, and similarities to the other. In this guide, we'll be comparing the two distributions across a few key areas and giving a brief review of both distros. Read on to learn more about Pop!_OS and Ubuntu, and how they compare. By the end of this article, you'll be armed with enough information to choose the best distro for your needs.
