RailsCasts (Mobile)

Summary: Every other week you will be treated to a new, free RailsCasts episode featuring tips and tricks with Ruby on Rails, the popular web development framework. These screencasts are short and focus on one technique so you can quickly move on to applying it to your own project. The topics are geared toward the intermediate Rails developer, but beginners and experts will get something out of it as well. A Pro option is also available containing more screencasts each week. This version is for mobile devices which cannot support the full resolution version.

 #412 Fast Rails Commands | File Type: video/mp4 | Duration: 8:06

Rails commands, such as generators, migrations, and tests, have a tendency to be slow because they need to load the Rails app each time. Here I show three tools to make this faster: Zeus, Spring, and Commands.

 #393 Guest User Record | File Type: video/mp4 | Duration: 9:27

Instead of presenting a sign up form to the user, consider creating a temporary guest record so the user can try out the application without filling in their information up front. They can then become a permanent member afterwards.
