Docker issues are frequently logged for DNS resolution in containers because it doens't inhert or get values for DNS from NetworkManager which leverages a built in dnsmasq to inteligently manage DNS.

Perminant workarround

sudo bash -c "echo listen-address=$(ip -4 addr show dev docker0 | grep -oP '(?<=inet\s)\d+(\.\d+){3}') > /etc/NetworkManager/dnsmasq.d/docker-bridge"
sudo systemctl reload NetworkManager
sudo bash -c 'echo -e "{\n\t\"dns\": [\"$(ip -4 addr show dev docker0 | grep -oP "(?<=inet\s)\d+(\.\d+){3}")\"]\n}" > /etc/docker/daemon.json'
sudo systemctl restart docker

Step 1 - Create a New SSH Key

We need to generate a unique SSH key for our second GitHub account.

ssh-keygen -t rsa -C "your-email-address"

Be careful that you don't over-write your existing key for your personal account. Instead, when prompted, save the file as id_rsa_COMPANY. In my case, I've saved the file to ~/.ssh/id_rsa_work.

Step 2 - Attach the New Key

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

Note: as @clibois mentioned below, due to the DRM Netflix uses, all decoding has to be done in CPU, making it somewhat choppy.

Note 2: Even the RPi 3 suffers from these CPU limitations. There is the potentially risky option of overclocking your RPi 3, but I haven't tried this.

If you manage to get smooth playback, please contact me, or post your solution here

UPDATE: I can no longer get this method to work. I have tried using Chromium v47, and v48, and both result in Netflix error "Oops, something went wrong" / C7053-1807, for which I can find no description online. If you manage to get things up and running, please contact me!

Vim, Vundle and ConEmu on Windows

Let's start by getting it out on the table: Sublime Text is great, and version 3 should no longer be considered "abandonware" as of build 3065. Sublime Text served me very, very well over the years. That said, trying out new things is a major part of leveling-up, and in that vein Vim deserves a go. (And have you seen some of those thoughtbot guys flying around in Vim? It's awesome!)

Getting Vim up-and-running on your Windows machine doesn't have to be an all-day project. In this post, we'll walk through:

Installing gVim, which gives us both the "classic" command line version as well as the graphical version
Installing Vundle, the best way to handle Vim-enhancing packages
Installing ConEmu, a supercharged command line emulator for Windows
