Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

Requirements

Encrypt everthing including /boot and /root
Enter password once
Support UEFI

Installation media setup

Download NixOS minimal iso and copy to USB stick. For example on Mac OSX

$ diskutil list
$ diskutil unmountDisk /dev/disk1 # Make sure you got right device

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

Part 1

Proof of concept

Say, you want to save your D3 application in a CouchDB database. This is just a proof of concept that this is possible. I use the »Focus + Context« diagram by Mike Bostock (http://bl.ocks.org/1667367) as an example.

Prerequisites:

A running CouchDB (see http://couchdb.apache.org/; in my Windows installation CouchDb is started as a Windows service when Windows starts).
An installation of couchapp (how to install couchapp, see http://couchapp.org/page/index).
Your favorite editor.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
	# So here's a minimal Gist which worked for me as an install on a new M1 Pro.
	# Inspired by https://github.com/malob/nixpkgs I highly recommend looking at malob's repo for a more thorough configuration
	#
	# Let's get started
	#
	# Let's install nix (at the time of writing this is version 2.5.1
	curl -L https://nixos.org/nix/install \| sh

	# I might not have needed to, but I rebooted

	#!/usr/bin/env bash

	# Author: Ned Letcher
	#
	# This bash script is designed to configure a clean Ubuntu installation (eg new
	# EC2 instance) with a somewhat opionated set of packages and tools for working
	# on Python projects. In addition to installing a range of packages for dev
	# work, it installs pyenv for the current user, overwriting the current .profile
	# and modifying the existing .bashrc to make sure pyenv is configured correctly.
