# 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

# 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.

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

candeira

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

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 git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.
