Switching between AHCI and RAID on the Dell XPS 15 (9560)

This guide likely applies to other models and, potentially, even laptops from other OEMs that have NVME drives. However, I've only tested this on my Dell XPS 15 (9560) with the OEM Windows installation from the Signature Edition model.

Switching from RAID to AHCI

Switching from RAID to AHCI is significantly simpler than switching from AHCI to RAID. All that's needed is a successful boot to Safe Mode.

To set the default boot mode to Safe Mode, use msconfig.exe or open an admin cmd/PowerShell window and run:

On master and nodes

Pull images form internet access laptop

docker pull gcr.io/google_containers/kube-apiserver-amd64:v1.5.0
docker pull gcr.io/google_containers/kube-controller-manager-amd64:v1.5.0
docker pull gcr.io/google_containers/kube-proxy-amd64:v1.5.0
docker pull gcr.io/google_containers/kube-scheduler-amd64:v1.5.0
docker pull weaveworks/weave-npc:1.8.2
docker pull weaveworks/weave-kube:1.8.2

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Prerequisites

Set up cmder to use msysgit / bash by default

Install cmder_mini (msysgit is already installed, so no need for full version)
In Cmder, open settings: Win + Alt + P
Under Startup > Tasks, add a task called {bash} with the following settings:
- Task parameters (set icon):
  - For Cmder icon: /icon "%CMDER_ROOT%\cmder.exe"
  - For Git icon: /icon "C:\Program Files (x86)\Git\etc\git.ico"
- Commands (open Git's bash shell):
"C:\Program Files (x86)\Git\bin\sh.exe" -l -new_console:d:%USERPROFILE%

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

	SSH_KEY=<ssh_key>

	mkdir -p $HOME/.ssh
	touch $HOME/.ssh/authorized_keys
	echo $SSH_KEY > $HOME/.ssh/authorized_keys

	chmod 700 $HOME/.ssh
	chmod 600 $HOME/.ssh/authorized_keys
	chown -R $(whoami):$(whoami) $HOME/.ssh

	// config/passport.js

	// load all the things we need
	var LocalStrategy = require('passport-local').Strategy;

	var mysql = require('mysql');

	var connection = mysql.createConnection({
	host : 'localhost',
	user : 'root',

	# I don't remember where I found this. o_O

	# Reset
