Remapping mouse buttons and keyboard keys could be a difficult thing to do in Linux due to the X Window System (X11) and Wayland confusion. However, there is a GUI tool written in Python called Input Remapper that can help you remap devices with ease. It supports both protocols, and remembers the configuration after rebooting.

input-remapper was formerly named as key-mapper.

Installation

Debian/Ubuntu

Download .deb file from release page then:
```
$ sudo apt install /path/to/deb/file
```
Arch Linux/Manjaro
```
$ yay -S input-remapper-git
```

Using `pip`

For other Linux distros or if you preferred managing input-remapper with pip:

$ sudo pip install --no-binary :all: git+https://github.com/sezanzeb/input-remapper.git

Enable the service manually:

$ sudo systemctl enable input-remapper

Usage

Configure PPPoE DSL Connection on Arch Linux/Manjaro with pppoe-setup

Most ISPs (Internet Service Providers) offer multiple dynamic IP addresses and even come with a static one. To take advantage of that, we'll be setting up a PPPoE (Point-to-Point Protocol over Ethernet) DSL (Digital Subscriber Line) connection on our own machine to obtain an independent IP address.

Two Ways to Install Packages from AUR on Arch Linux/Manjaro

Just like Debian/Ubuntu's package manager apt, Arch Linux/Manjaro has its own package manager called pacman to help you install packages. But the story doesn't end there. On Arch-based Linux you can even install community-maintained packages from AUR (Arch User Repository), which is a lot like PPA (Personal Package Archive) of Ubuntu.

Auto-Renew Let's Encrypt Free Certificates for Nginx on Linux

More than 75% of all websites use HTTPS nowadays. Serving content over HTTPS is not only good practice for search engine optimization (SEO), but essential for security reasons, especially for those requests containing sensitive information.

Create/Remove/Resize Swap Space without Modifying Partitions on Linux

When a Linux machine runs out of physical memory (a.k.a random-access memory - RAM), the swap space will be used instead. It literally swaps data from your RAM to your disk space to free up memory. In some perspectives, it even speeds up your CPU too, since when the less the memory is free, more time the CPU spend on GC (Garbage Collection).
