If you ever get bored of your ordinary, default Ubuntu desktop or you feel that you do not utilize your video card the way you should, you could enable the 3D cube effect to give your desktop an extra spark. This effect is provided by Wayfire, a 3D compositor for Wayland.

Stratis is a free and open source storage management system developed by Red Hat. Available as a technology preview since RHEL 8, it gained full support starting from version 9.3 of the distribution, and can be used also on Fedora. Stratis relies on existing storage technologies such as LUKS, device mapper, and the XFS filesystem, to provide features similar to those integrated in the BTRFS and ZFS filesystems.

Ubuntu is one of the most popular Linux distributions, well known for its ease of use and wide range of available software. In some cases, software comes in the form of .deb packages that need to be installed on your system. When faced with multiple .deb packages, especially when they have dependencies, installing them one by one can be time-consuming.

Vim is a powerful, highly configurable text editor used primarily in Linux, macOS, and other Unix-based systems. Despite its widespread use, one of the most infamous challenges, especially for beginners, is figuring out how to exit Vim after editing a file. Unlike more modern text editors, Vim relies on keyboard commands rather than menus or buttons, which can be a hurdle for those unfamiliar with it.

A snapshot is an image of a filesystem state at a specific point in time. Snapshots are really useful to “turn back time” and bring the system to a known good state if something goes wrong. At the time of writing, there are two main native ways we can create atomic snapshots on Linux: by using LVM (Logical Volume Manager) or by creating a BTRFS filesystem, which has snapshots as a built-in feature.

When working with the Linux command line, the .bash_history file plays a vital role by storing the commands you have executed. By default, the commands are stored only when you exit your terminal session, meaning they might not be saved in real-time. However, it can be beneficial to ensure that all commands are saved to the .bash_history file immediately after execution.

SNMP (Simple Network Management Protocol) is widely used for network management and monitoring. Installing SNMP on RHEL/CentOS systems allows you to monitor various system statistics, interfaces, and other crucial metrics. This guide will walk you through the detailed steps to install, configure, and test SNMP on your RHEL/CentOS system.

Encrypting and decrypting files and directories securely is essential for protecting sensitive data. OpenSSL, a powerful open-source tool, provides robust encryption and decryption capabilities that can handle files of any size, from small text files to large binaries, and even entire directories.

Linux is a powerful operating system that provides a wide range of tools for network management and configuration. Whether you are troubleshooting network issues, configuring new devices, or just exploring your system’s network setup, knowing how to obtain information about network devices is essential.

The nc (netcat) command is a versatile tool that allows Linux users to transfer data over a network. This method can be useful for quickly moving files between systems without needing additional data transfer protocols like FTP, HTTP, or SCP. In this tutorial, you will learn how to transfer a file between two Linux systems using nc, with one system acting as the server (sending the file) and the other as the client (receiving the file).

Amazon Kindle supports a limited number of eBook formats, making it essential to convert your files to a compatible format before sending them to your device. If you are a Linux user, there are several tools at your disposal to help with this conversion process. In this guide, we will cover how to use popular tools such as ebook-convert, calibre, and unoconv to convert various eBook formats to Amazon Kindle-supported formats.

When working with the Cron time-based scheduler in Linux, you might find yourself needing to execute tasks at intervals of less than one minute. However, the native capabilities of Cron do not allow for such granular scheduling. By default, Cron’s smallest interval is one minute. This can be limiting for certain applications where tasks need to be run every few seconds or at a more precise time interval.

Security professionals often need to use a variety of operating systems to perform their tasks. Dual booting Kali Linux and Windows 11 grants users the ability to switch back and forth between systems, depending on the work that needs done.

Remote desktop is a feature that allows a user to log into another system and control it the same way they would if they were sitting right in front of it. You are able to see the screen exactly as it appears on the remote system itself, and use the keyboard and mouse.

Rsnapshot is a free and open source utility which works as a wrapper around Rsync to perform incremental snapshots of local or remote systems via SSH. Hard links are used to save space when backing up unchanged files, to preserve space while still displaying complete filesystems to the user. In this tutorial, we learn how to install and configure Rsnapshot on some of the most used Linux distributions.

If you want to be able to run both Ubuntu Linux and Windows 11 on your PC, one option is to implement a dual boot configuration. This will give you the best of both worlds by allowing you to boot into either Ubuntu or Windows 11 whenever you turn on your computer. Having access to both operating systems is a powerful option in which you can take advantage of both system’s abilities.

Encryption is a crucial aspect of securing sensitive information on your Linux system. One of the tools you can use for this purpose is mcrypt, which provides symmetric encryption and decryption capabilities. This guide will walk you through the process of using mcrypt to encrypt and decrypt files and directories on Linux, covering a range of options and examples.

The sed command, short for stream editor, is a powerful tool in Unix and Linux systems used for parsing and transforming text. One of the common tasks performed with sed is substitution, where you replace occurrences of a specific pattern within a file or a stream.

Security-Enhanced Linux (SELinux) is a powerful security module that provides mechanisms for supporting access control security policies. When managing files and directories on a SELinux-enabled system, it’s crucial to preserve their SELinux context to maintain their security properties. This article will guide you through the steps to copy files and directories while preserving their SELinux context on a Linux system.

Web Distributed Authoring and Versioning (WebDAV) allows users to collaboratively edit and manage files on remote web servers. This guide will walk you through the installation and configuration of a WebDAV server on Ubuntu and Debian using Apache2.
