      • UNIX CopHow To Enable HTTP2 in NGINX

        HTTP2 is the natural evolution of HTTP. Thanks to it, we will have an improvement in the speed of response due to its architecture that allows with a connection to make several requests and responses.

        Another interesting aspect of HTTP2 is that it eliminates the sending and receiving of redundant information. In addition to this, everything is done securely so that the Internet experience becomes more efficient.

        For these and more reasons is that many sysadmin and webmasters choose to enable this protocol in all their configurations. Today we will do the same using Nginx.

      • Linux CapableHow to Install Flatpak on Ubuntu 22.04 LTS

        Flatpak is a tool for deploying and managing software packages on the Linux operating system. It provides an isolated environment where users can run applications without affecting other parts of their computers.

        With Flatpaks, installing an application is like pulling it into your local repository. Links have then generated that point from the right places in Filesystem to where you can find these files–these hard links will be efficient for disk space since they’re simple compared with doing things through traditional methods.

        Most Ubuntu LTS users know that the distribution focuses on stability over newer features, especially once the LTS has aged after its initial release with packages being frozen. For example, you may want to install the latest version of an application such as Discord, VLC, Spotify, or Ubuntu does not have the application together, making often third-party package managers use it as a backup.

        In the following tutorial, you will learn how to install Flatpak on Ubuntu 22.04 LTS Jammy Jellyfish and enable Flathub to search, install, maintain or remove Flatpak applications as an alternative the standard APT package manager, Launchpad PPA’s and especially Snap packages from Snapcraft.io.

      • Bash script: YES/NO prompt example

        Interactive Bash scripts will often include a yes or no prompt in order to ask for user verification before proceeding with a set of instructions or canceling the procedure.

        If a user answers yes to the prompt, the Bash script will typically proceed with its task, and if a user answers no, the script will either exit or move on to a different part of the script.

        In this tutorial, you will see how to create a yes/no prompt in a Bash script on a Linux system. See some of our examples below to learn how a yes/no prompt works.

      • Bash Scripting: Read input from command line

        We can make a Bash script interactive by prompting a user for input. This can be done from the command line, with our script waiting for user input in order to proceed further.

        The principal way to do this is via the read command. Although it is also possible to read input in the form of command line arguments that are passed to the Bash script when it is executed.

        In this tutorial, you will learn how to read input from the command line with a Bash script and the read command.

      • How to Change Hostname in Linux

        If it’s connected to the internet, your computer has an address. It’s like the street address for your house, but other computers just use a series of numbers.

        To make it easier for us humans to remember, we also assign a hostname using words. If the need arises, here is how to change hostname in Linux.

      • How to Open/Allow incoming firewall port on Ubuntu 22.04 Jammy Jellyfish

        The default firewall on Ubuntu 22.04 Jammy Jellyfish is ufw, which is short for “uncomplicated firewall.” When enabled, the firewall will block all incoming connections by default.

        If you want to allow an incoming connection through ufw, you will have to create a new rule to allow a certain port or multiple ports. We can also specify that only connections from a certain IP address or network range can gain incoming access, while blocking all others. This is all done from the command line and is quite simple once you know the proper syntax.

        The objective of this tutorial is to serve as a quick reference guide on how to allow incoming traffic on any TCP or UDP port using Ubuntu 22.04 Jammy Jellyfish Linux with UFW firewall.

      • How to configure Samba Server share on Ubuntu 22.04 Jammy Jellyfish Linux

      • How to manage EFI boot manager entries on Linux

        UEFI is the firmware interface which on modern machines has superseded the legacy BIOS. One of the features of the UEFI firmware is being able to store boot entries in the persistent and editable NVRAM memory (Non Volatile RAM). While installing a Linux distribution (or any other operating system) in UEFI mode makes usually the related boot entry to be written to the NVRAM, in some cases we may want to perform manual operations such as modifying the boot order, creating or deleting a boot entry.

        To accomplish such tasks on Linux we can use the efibootmgr utility. In this tutorial we see how to install it on some of the most used Linux distributions, and how to use it to manage NVRAM boot entries.

        • Distro WatchReview: XeroLinux in 2022

          XeroLinux is a distribution based on Arch Linux with a focus on eye candy. The distribution is available in three editions: Main (which runs the KDE Plasma desktop), GNOME, and Xfce. Each edition is available for 64-bit (x86_64) machines exclusively.

          I couldn't find a whole lot of other useful information about XeroLinux from its website or forum, other than it uses the Calamares system installer, requires a network connection during the install process, and the project appears to be the work of a single developer who is not interested in fielding support requests from Wayland users: "I have finally added KDE Wayland Session to ISO, enabling you to use it. But it's not all roses, yet. Especially if you are an NVIDIA owner like I am. Yes, if you are, then you are either out of luck, since NVIDIA did not yet bake the required modules into the driver yet, so you will have to do some tinkering to get it to work. If you do not feel comfortable or confident enough to do it then just use Xorg (X11) to log in and skip Wayland for now... Kindly note, that I will not be providing support in that area since, I am not yet confident in using it."

          The latest version appears to have been released on January 3rd of 2022, though the project doesn't offer any version information attached to its ISO files. I downloaded the Main/KDE edition which is 2.7GB in size.

          • Linux HintPython Inline If-Else

            Python programming language is readable and efficient in writing operations. In this article, the discussion is on inline if-else conditional statements. Python doesn’t have a ternary operator, so we use if-else in a single line that has the same effects as ternary operators. This condition evaluates conditions in a state of being true or false.

            As inline if-else statements are logical statements that offer a single line that preserves code quality by replacing the multiple lines of if-else code. Inline if-else statements should be used with the expressions and their execution based on the evaluation conditions.

            Object-oriented Java programming provides a concept of inheritance that makes it possible for a class to inherit the class attributes and methods of other classes. The class that inherits the characteristics of some other class is referred as a child/derived/sub-class, while the class whose characteristics are inherited is referred as a parent/base/super-class.
