In this micro talk, I'll review the basic theory behind hash functions and hash tables, show you the new internal data structures that Ruby 2.0 uses to save keys and values, and present some performance data that proves this optimization exists and how much time it will actually save you.

From @username1:
- This layout is just a suggestion.
- It's kinda based on how Wikipedia is organized (e.g. an "External Links" section)
- Bullet points might work well. Paragraphs too. Up to you. :)
- This section is probably enough, but just in case here are some other ideas...
From @username2:
- It's best to leave "username dividers" to prevent merge conflicts later.
TODO
- If some stuff is controversial, thought provoking, etc, we can have something like this.
- Kind of like "Talk" pages on Wikipedia.
