Desktop shortcuts creation in Linux
Many people find it useful to organize some of their most frequented applications as shortcuts on their desktop. This allows for quick launching of programs or custom shortcuts. Although most Linux systems rely on a sidebar app launcher or start menu, desktop shortcut launchers can allow you to open applications or websites super fast, since they live right on your desktop and make the targets only a click away.
Ansible Vault Tutorial
In previous tutorials we discussed Ansible, a great tool we can use for automation and provisioning. We talked about basic Ansible concepts, we saw some of the most used Ansible modules, how to manage variables and how to perform basic loops in playbooks; now it’s time to see how to protect sensitive information which sometimes may be needed to accomplish some tasks. In order to protect sensitive information when using Ansible, we encrypt them with Ansible Vault.

Ping sweep script to scan and monitor network
In this tutorial, we will provide a few Bash scripts to scan and monitor the network using combination of commands such as ping
. Obviously, these scripts are no match to a full monitoring dedicated software like nagios, but they could be useful for small home brand networks, where implementing sophisticated monitoring systems can become too much overhead.
C++ : Understanding pointers
This tutorial is intended for all programing enthusiasts on all levels that wish to understand pointers in the C++ language. All code presented here is not compiler-specific, and all examples will be written in plain ANSI C++.

Show Bash script usage
Is it best practice to include usage in every Bash script that you create. This gives the user an idea of what options the script is expecting, so they can use it as intended. It also gives the script some error checking ability to make sure that the user has supplied arguments in the expected way.
