Update(May 2007): I am only updating the hosting at ShowMeDo. (nice quality, etc.)
For those who were waiting for an alternative to Vuze, I uploaded the video to Revver. For some reason, the second video got approved before the first. The first one is still up at Vuze(Keyword: Introduction to Ruby) Right now, the Flash version at Revver seems to be up and running. I think it will take a little time for the Quicktime version to be up.
Here is the link. You can also click on this thumbnail
Thanks to Allan over at http://xcoding.wordpress.com for the hint about Revver.
Screencasts I am working on Ruby screencast, Part III and an “advanced introduction” Cocoa tutorial.
Of course, you can also download the MOV file from Revver or Vuze, if you want better quality
