How to setup landslide to work with LaTeX rendering

This short howto is intended to be a mental note for myself so I don't have to spend all the wasted hours that took me to figure out howto get landslide up and running and beautifully displaying LaTeX on the slides. If you find it useful, good for you ;-)

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:

• Encrypted Root on NixOS - Nix Wiki
• Installing NixOS - Chris Martin
• Linux administration and use - Earl Douglas
• Installing NixOS on a ThinkPad W540 with encrypted root - Bluish Coder

Requirements

1. Encrypt everthing including /boot and /root
2. Enter password once
3. 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

In https://github.com/ekmett/lens/wiki/Derivation, we see some types for
composition of compositions: (.).(.), (.).(.).(.), and so on. Let's prove that
the type of (.).(.) is (a -> b) -> (c -> d -> a) -> c -> d -> b, as stated in
the site. We'll stick with prefix notation, meaning that we want the type of
(.)(.)(.).

Recall the type of composition. This should be intuitive:

  (.) :: (b -> c) -> (a -> b) -> a -> c                                      [1]
