> Install the official Nvidia drivers if you use a Linux machine for graphics design or gaming. While most recent Linux Desktop systems have the Nouveau open-source graphics device driver for Nvidia video cards, it is not as feature-rich as the official Nvidia driver. The official Nvidia driver offers improved performance and additional functionality, making it the superior solution for demanding workloads. Installing the driver is simple, although it does need a few steps. To begin, identify your graphic card model and locate the necessary driver on the Nvidia website. After downloading the driver, you must unzip it and execute the installation. Following these instructions, you should see improved performance from your Nvidia card.
> If you use open source projects from GitHub or GitLab in your infrastructure, you have probably established workflows to create project builds that you can install. You might create builds regularly and execute them in a similar manner across projects. Let's say you want to build the code changes in Fedora Linux or CentOS Stream for each commit, release, or pull request in these projects. Packit can automate this policy, fold into a CI/CD pipeline, and do even more.
> Packit is an open source project that tests and builds RPM packages on Fedora Linux, CentOS Stream, and other distributions to ease the integration of upstream projects with the distributions.
> This article focuses on Packit Service, which operates on GitHub and GitLab. You can also install a command line interface (CLI) locally to run Packit on your desktop or laptop.
> SSH or Secure Shell program is renowned for its secure operation of network services via a cryptographic network protocol. In most cases, the network interface in use has questionable security hence the need for SSH.
> To understand the concept of a segmentation fault in a Linux operating system environment, we have to first address the concept of segmentation. In operating systems; under process management, each process is associated with a distinct virtual address space, hence the concept of segmentation.
> Supposing a memory location like 0x877 is evident on your Linux operating system. Also, suppose two processes (A and B) have access to read this memory location (0x877).
> When you decide to fully dive into the Linux system ecosystem, you will soon realize that time is never fully on your side. You will want an organized time map to manage your computing objectives but find yourself failing to check some boxes just because you have not yet discovered the importance of having a calendar and scheduling tool on your Linux system.
> This article will walk us through the installation and basic usage of a CLI-based calendar and scheduling tool called Calcurse.
> Vi has been around for a long, developed around 1976, it offered users traditional yet powerful features such as an effective editing interface, terminal control, and many more.
> However, it lacked certain captivating features for example multiple screens, syntax highlighting, multiple undo functionality, and so on, that many Unix/Linux users were looking for in a complete text editor.
> The command zfs create is used to create ZFS datasets. No surprise there. With the -V option, a volume is created rather than a regular dataset (e.g. a filesystem). So let’s create a 16GB volume on the pool called zippy (that’s a single SSD scratch drive attached to my system; the name isn’t important and your pool will probably be called something else).
> zfs create -V 16G zippy/freebsd12-test
> Now there’s a /dev/zvol/zippy/freebsd12-test character device. This can be written to. For all intents and purposes, it is a disk. The next step is to tell VirtualBox about the existence of this new disk. This is best done while VirtualBox (the UI) isn’t running.
> The rmdir command is used to remove empty directories. If you attempt to remove a non-empty directory with this command, you’ll encounter the Rmdir Directory Not Empty error.
> That much is intended behavior, but some users have reported cases where they faced this error despite using rmdir on an empty directory. This happens due to reasons like file system errors or broken symbolic links.
> There are only a few special characters involved in working with character strings on the command line or in a script on Linux: the single quote, the double quote and the backslash. But the rules aren’t as obvious as one might think. In this post, we’ll look at the easy and the somewhat tricky uses of these special characters.
> The watch command allows you to rerun commands in a loop until you stop it or run into a condition that stops the looping for you. It can be very useful when you're waiting for something to change before you can move on to the next task.
> Running out of disk space? It is time to find out which directories and files are occupying the most disk space. Fortunately, checking Linux disk space is made easier with Agedu utility. This guide explains what is Agedu, how to install Agedu, and how to check disk space in Linux and find wasted disk space using Agedu.
