Jan 23, 2012 | 14 minutes | Rack, Code Walkthrough
Here I describe each Rack middleware that is included in a Rails app which will give you a better understanding of what a request goes through behind the scenes before it hits your application.
Foundation

Upgrading to Rails 4
With the release of Rails 4.0.0.rc1 it's time to try it out and report any bugs. Here I walk you through the steps to upgrade a Rails 3.2 application to Rails 4.

Batch API Requests
Here I demonstrate how to perform bulk API operations though a single request using Rack middleware. This is great if you need to trigger multiple actions at once such as if the user goes offline.
