Set up default audio device on Ubuntu 20.04 LTS

Problem

I have a notebook connected to a port replicator. I want to use the build-in speakers and microfone and not the external ones. If I boot my notebook in my port replicator Ubuntu changes the devices to external.

Solution

  1. Find your internal speaker

Installing latest Docker on a Raspberry Pi 3

Introduction

I wrote this gist to record the steps I followed to get docker running in my Raspberry Pi 3. The ARM ported debian version (Jessie) comes with an old version of docker. It is so old that the docker hub it tries to interact with doesn't work anymore :)

Hopefully this gist will help someone else to get docker running in their Raspberry Pi 3.

Installation

From original instructions at http://blog.hypriot.com/post/run-docker-rpi3-with-wifi/

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺
