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

;; PROBLEM:
;; Create function that satisfiy following example

(check-expect (number-list (list "first" "second" "third"))            
              (list "1: first" "2: second" "3: third"))
              
(define (number-list n) empty) ; stub

;; #1 Objective:

;; yell-starter.rkt

; PROBLEM:
; 
; DESIGN a function called yell that consumes strings like "hello" 
; and adds "!" to produce strings like "hello!".
; 
; Remember, when we say DESIGN, we mean follow the recipe.
; 
; Leave behind commented out versions of the stub and template.

; Problem: Design a function that pluralizes a given word.
; (Pluralize means to convert the word to its plural form.)
; For simplicity you may assume that just adding s is enough to pluralize a word

;; What is an appropriate signature for this function?

• Dactyl & Dactyl Manuform Case Preparation

• https://keeb.io/products/amoeba-single-switch-pcbs

• https://lewisf.com/dactyl-manuform/ hold ; and use hjkl to left,right, up,down

• Both part needs to have ProMicro MicroController so It can use the QMK Firmware for controling the keys on keyboard itself

• 4x6 is the way to go

There’s a strong trend for ergonomic keyboards to reduce the number of keys, mostly becouse of QMK framework that allows layering. People usually prefer less rows.
