Generating a properly secure SECRET_KEY in Django
"""
Two things are wrong with Django's default `SECRET_KEY` system:
1. It is not random but pseudo-random
2. It saves and displays the SECRET_KEY in `settings.py`
This snippet
1. uses `SystemRandom()` instead to generate a random key
2. saves a local `secret.txt`

Git Conventions

You've been working locally for awhile. You're ready to push some changes, but someone else pushed something! You have to pull in their changes before you can push yours.

git pull origin master forces you to create a merge commit, which is annoying.

Instead, do git pull --rebase origin master. This will effectively:

  1. Stash your changes
  2. Pull in the changes from origin
  3. Apply your changes on top

No merge commit!
