Huawei Freebuds Pro - Linux (KDE Neon) configuration and AAC audio

The default configuration of KDE Neon does not work with the headphones. I have managed to connect them doing some changes, and adjusting some configurations. This resumes that, to keep it if I need to reconfigure them in the future.

This configuration has worked for me using the following setup:

• KDE Neon 5.20, kernel 5.4.0
• Freebuds Pro version 1.9.0.256

Git Crash Course for Beginners

Preface

A good understanding of Git is an incredibly valuable tool for anyone working amongst a group on a single project. At first, learning how to use Git will appear quite complicated and difficult to grasp, but it is actually quite simple and easy to understand.

Git is a version control system that allows multiple developers to contribute to a project simultaneously. It is a command-line application with a set of commands to manipulate commits and branches (explained below). This tutorial will help you get started, and in no time you will be a Git Ninja!

Contents:

• How Git Works
• Installing Git on your Machine
