Download Vagrant boxes manually

In this example, we're going to download the Midnight Sun box.

# The box URL is https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0
# In general, we just take the box URL, and then append the provider URL
# https://app.vagrantup.com/<organization name>/boxes/<box name>/versions/<version>/providers/<provider>.box
wget https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0/providers/virtualbox.box -O box-2.1.0.box

Debugging Redis Keyspace Misses

Simply put, a keyspace "MISS" means some piece of data you tried to retrieve from Redis was not there. This usually means that one of the following things happened:

1. The key expired
2. They key was renamed
3. The key was deleted
4. The key was evicted due to memory pressure
5. The entire database was flushed
6. The key was never actually inserted
