Setup nix, nix-darwin and home-manager from scratch on an M1 Macbook Pro
# 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

Created June 27, 2021 01:08 — forked from ned2/ubuntu-ec2-init.sh
A Bash script for initialising a clean Ubuntu installation and user account with a pyenv-based workflow.
#!/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.

A real world usage for git subtrees.

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.
