Top Ruby screencast resources

As you know there are several way to kick-off and learn a new programming language, environment or special tools:

• tutorial
• screencast
  

But, now screencast is more popular for effective start and feature demonstration. So, I'm trying to collect as more as possible screencast resources for learning Ruby and Rails.

• http://railscasts.com, it's the most popular free Rails screencasts
• http://sdruby.com, it's San Diego's Ruby community, there are about 59 Ruby and Rails screencasts
• http://www.rubyplus.org/episodes, Free Ruby and Rails Screencast, about 93 episodes
• http://www.tekniqal.com, there are 17 tutorials covering basic Ruby topics
• http://www.confreaks.com/events, here is located videos from several Ruby conferences
• http://showmedo.com/videotutorials/ruby and http://showmedo.com/videotutorials/rubyonrails, it's great resource for learning from ground up. There are a lot of interesting videos for beginners. Also, this resource includes other areas, not only Ruby/Rails related
