                Springer made a bunch of books available for free, these were the direct links
              
          
    These links no longer work. Springer have pulled the free plug.

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`

                Instructions for exporting/importing (backup/restore) GPG keys
              
          
    Every so often I have to restore my gpg keys and I'm never sure how best to do it.  So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.
Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
