> In this tutorial, we will show you how to install Wireguard VPN on Ubuntu 22.04 LTS. For those of you who didn’t know, WireGuard is a free and open-source virtual private network (VPN) software that uses state-of-the-art cryptography to secure and encrypt internet connections. It is designed to be simple, fast, and easy to use, and it has a small codebase that is easy to review and audit.
> 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 Wireguard on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
> OpenCV (Open Source Computer Vision) is a free and open-source library of computer vision and machine learning algorithms that can be used to process and analyze images and video. It is widely used in a variety of applications, including object detection, image, and video processing, and augmented reality.
> In this article, we will cover two different methods for installing OpenCV in Python: using “PIP” (the Python Package Manager) and using “Anaconda” (a free and open-source distribution of Python and R for data science and machine learning).
> To count the overall number of lines, syllables, and letters in a text document, use the “wc” Bash function, which means “word count”. It is presented with four columns in the output. The first of which displays the number of lines. The second column lists the words in the file. The third column lists the characters. And the final column lists the file name. This “wc” command gives us access to several flags including “-c”, “-w”, and others which we will cover in this article.
> When writing a script or executing a command, it makes sense to know if it succeeded. In Linux, when a command is run, we get an exit code which confirms whether the executed command was successful. When running a command that relies on the output of the other command, you must fetch the exit code of the first command to determine whether the other command will run. This guide focuses on two ways of checking whether a command succeeded in Bash.
> In a BASH environment, we construct an alias for a set of files. Alias can be made more programmatic and versatile by using BASH functions, variables, etc. Bash Alias is a method for creating a few shortcut commands for numerous and repetitive operations. Here, we will discuss a way to create the bash alias with the arguments and parameters. Unfortunately, there are some cases when the alias does not accept parameters or arguments. However, we can utilize functions to accept parameters and arguments while executing alias commands. We use the bash aliases and functions to use the command line more efficiently.
> Kubernetes is challenging. Of that, there is no debate. Not only are there a lot of moving parts that go into deploying a container to a Kubernetes cluster, but so much can go wrong along the way. To complicate matters even further, deploying the Kubernetes cluster can be a hair-pulling affair.
> That’s why tools like Canonical’s MicroK8s have been developed. With such software, the process of deploying a Kubernetes cluster is significantly less challenging, so you can focus more on getting up to speed with deploying applications and services to the cluster.
> Want to install the popular Mozilla Firefox alternative Google Chrome browser in Redhat 9 or RHEL 8? Then there here are the steps to follow, given in the tutorial.
> Chromium-based Chrome browser is the most preferred choice for home or regular desktop users. It is available free of cost to install not only on Mac and Windows but also on most of Linux systems. Although Chromium is open source, Google’s Chrome is a proprietary browser.
