My favoriate Rails screencast

by Laurel Grosjean

The production quality is high, episodes focused, and new posts are frequent. Each episode is a 5-10 minute micro tutorial on some aspect of rails. These have been wonderful for someone like me who's read the various ruby books, but wants to get a better feel for the best ways to tackle specific problems. Highly recommended.

Great

by Andrew Mason

Very well done -- short and to the point. Podcaster does not appear to be as stoned as the peepcode guy.

Quick, informative, and well laid-out

by Kris Gosser

I have nothing buy high praise for the screencasts Ryan has been producing. Being not necessarily a beginner but definitely not a pro at Ruby on Rails, these screencasts have suited me perfectly. They don't cover such beginner topics like how to create an application or what the MVC is, nor are they an hour long and explain hardcore server-based hacking. No, these screencasts are noramlly very short and focus on the little things in Rails. I don't think of it as more or less "here's X, Y, Z of Rails." Rather, I think of them as "here's a better technique to do X, clean up Y, and get rid of Z" tutorials that really help out my programming. Thank you, Ryan.
