Java is a general-purpose, class-based, object-oriented multipurpose programming language that is popular due to the design of having lesser implementation dependencies, meaning that the compiled Java code can be run on all platforms that support Java without the need for recompilation. Java is also fast, secure, and reliable, therefore. It is widely used for developing Java applications in laptops, data centers, game consoles, scientific supercomputers, cell phones, etc.

The tutorial will look at installing the OpenJDK version instead of the default Oracle JDK. The difference between these two is licensing. OpenJDK is an entirely free open-source Java with a GNU General Public License, and Oracle JDK requires a commercial license under the Oracle Binary Code License Agreement. Other differences are release schedules and other factors that come into play; however, performance is pretty much the same.

In the following tutorial, you will learn how to install OpenJDK 11 LTS or better known as Java 11 LTS on Ubuntu 20.04 LTS Focal Fossa with the standard APT installation from Ubuntu’s repository along with the PPA version which may suit some users better. The tutorial will also demonstrate how to switch Java alternative default versions.

Telegram is a free, cross-platform messaging app with end-to-end encryption. It’s famous for providing video calling and other missing features from Facebook or Twitter – one of its main attractions! The application also has no ties whatsoever between them (the big social media companies), meaning you can be sure your data won’t go unnoticed by anyone else besides whom it belongs too; this makes telegram more secure than ever before because there isn’t anything giving away how much information we share on our phones every day.

In the following tutorial, you will learn how to install the Telegram client on Fedora 36 Linux using the command line terminal with two installation methods and some tips on maintaining Telegram into the future.

If you’re not familiar with MATE Desktop Environment, it’s the continuation of GNOME 2. This lightweight and fast desktop environment run on Linux or most BSD operating systems; an excellent choice for low-end systems looking to remain efficient system resources! The newest version includes Wayland support which means that components can take advantage of its robust graphics processing capabilities without relying upon X11 servers (which some may find unfavorable).

Fedora 36 has, by default, GNOME 42 installed. While this is an excellent option, alternatives can be installed in combination with the default desktop environments, and you can swap freely between them. However, if you genuinely love using the MATE desktop environment, I would advise installing the MATE Fedora spin alternative version without having multiple desktop environments.

GNOME 42 has arrived! This is a big release, introducing the libadwaita library to provide apps with not only a new look but adaptive design and animations. There's also official dark theme support and excellent screen capturing functionality built into the Print Screen button.

GNOME is a desktop environment for the Linux operating system. It is designed to be simple and easy to use, and it is one of the most popular desktop environments for Linux.

A desktop environment is a GUI (graphical user interface) that allows you to interact with your computer in a more natural way, usually with a mouse and keyboard.

Like any other desktop environment, it’s composed of a number of components, including a window manager, a desktop manager, a panel, and a set of applications.

GNOME is the default desktop environment for most Linux distros.

There are cases where your machine may not come with GNOME installed by default, such as when you’re running a server or you installed your RHEL-based distro from an image with a different default desktop environment (such as XFCE).

In this tutorial we’ll cover how to install GNOME on a machine running a RHEL-based distro, such as Rocky Linux, AlmaLinux, CentOS, Fedora, and others.

The other day, we discussed how to create and manage Linux disk partitions using Parted utility. Today, we will do the same with an another command line utility called 'Fdisk'. This tutorial explains what is Fdisk utility, and how to create and manage disk partitions with Fdisk in Linux.

For decades, Linux logging has been managed by the syslogd daemon.

Syslogd would collect the log messages that system processes and applications sent to the /dev/log pseudo device. Then it would direct the messages to appropriate plain text log files in the /var/log/ directory.

Syslogd would know where to send the messages because each one includes headers containing metadata fields (including a time-stamp, and the message origin and priority).

In this tutorial, we will show you how to install OTRS on AlmaLinux 8. For those of you who didn’t know, OTRS stands for “Open Source Trouble Ticket System” is a free and open-source service management suite.

OTRS has a low requirement which makes it ideal for small business ticketing.

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 OTRS (Open Ticket Request System) on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

There are many ways to create a bootable USB stick in Ubuntu. Some involve using the system tools, while others require external packages to be installed. In this article, we will use the Ubuntu command line, the terminal, to create a bootable Ubuntu USB stick. This is done with the dd command. The terminal is a good alternative to doing your tasks through the Ubuntu user interface. Using the terminal makes certain tasks more efficient and even faster. The command-line tools don’t consume too many resources, so they are a good alternative to the widely used graphical applications, especially if you can’t cope with older hardware.

This guide is intended for Linux beginners. It shows 6 different ways to find the IP address of your local network card using the command line as well as the GNOME Desktop on Debian 11.

An IP address is a unique identifier assigned to any system connected to a network or the Internet for identification and communication. It is a very important piece of information to know in order to set up network-related applications, troubleshoot network problems, and allow other users to access your system to share resources.

There are usually two types of IP addresses for a network device: the external IP address and the internal IP address. The external IP address is the address you get when you are connected to the Internet and is assigned to your router by an Internet service provider. The internal IP address is the address assigned to you by your router or Internet device that allows you to connect to the Internet.
