Redis: Zero to Master in 30 minutes

From here and here.

Order of operations

NOTE: failure at any point will simply exit with a status of zero

1. Looks for the required OPENMYMIND_RSS_URL environment variable.
2. Connects to Redis at localhost:6379.
3. Fetches the RSS feed from the URL set in OPENMYMIND_RSS_URL.
4. Decodes the XML in the RSS feed.
5. Ranges across every item found in the feed:
   1. Converts the entire item to JSON.
   2. Converts the publication date to a UNIX timestamp.
   3. Sets the value of Redis key item:<item guid> to the entire JSON payload.
   4. Adds the above key to a sorted set where the score is the publication date.
6. Gets the keys of the three most recent items from the sorted set.
7. For each of these keys:
   1. Gets the JSON payload back out of Redis.
   2. Decodes the JSON.
   3. Prints the item's title and publication date.
