 I nowadays rarely use Nano as a text editor, since I mainly rely on Emacs for all sorts of tasks, including quick file editing. However, at times, Emacs won’t work or won’t be available, and I therefore need a lightweight, fast and reliable text editor: Nano.

 Polybar is a desktop utility for displaying various information in form of bars for GNU/Linux systems. It is often used as a replacement for native bars available in window managers, such as i3. In my case, I use two instances of polybar in order to get two bars displayed on each screen. The information displayed is either related to i3 itself, or it is system information, such as CPU or disk usage. More information will be given and explained below.
