I like to work using an adapted Pomodoro technique, therefore I added a timer widget to my desktop (I use Kubuntu as my operating system). Unfortunately, in Kubuntu by default when the timer ends, there is no sound notification about this event. In this short post, I explain how to ring a sound when timer ends.
From time to time, I experiment with different tools. In order to have the same environment and to keep my working machine clean from the garbage left after such experiments, I do my investigations in a virtualized environment. Usually, my guest operating system (OS) is Ubuntu Server because I usually use this OS in the cloud. Thus, to completely resemble my experience in the cloud I should have terminal access to the guest operating system. Unfortunately, by default after you have installed a guest virtual machine (VM) you do not have network access to it. Therefore, in this article I will show how to configure VirtualBox and guest OSes so that you get access to your virtual machines from the host, e.g., through terminal.
