When I was looking for information on Rails Metal/ActionController::Metal the other day I was struck once again by what a great resource RailsCasts is.

The Rails Metal episode is still up even though it’s no longer applicable, providing a useful historical perspective. Even better, there’s a link right at the top to an updated video released 3 years later that explains how to achieve the same thing following the removal of Rails Metal.

It’s clear Ryan Bates put a lot of love and attention into the whole site!
