2. Introduction to Ruby II
This video is about creating one's own classes. I walk through a
bioinformatics class I ported from

http://www.onlamp.com/pub/a/python/2002/10/17/biopython.html (Oreilly
online's Beginning Python for Bioinformatics).
I talk about def initialize, instance variables, class variables, and a very quick note on

5. Introduction to Ruby V
I talk briefly about how CSV Reader includes Enumerable and defines each. I
talk about extracting information from a typical log file. I give an

point viewers to the first edition of Programming Ruby by Dave Thomas.

6. Introduction to Ruby VI: Debugging and Unit Testing
This screencast shows to debug a ruby program using the standard Ruby debugger. It also shows unit testing, a very simple TCP Server, an an introduction to some Ruby/Tk code which I will develop in the next screencast. There is more than one source file for the video, so you can find the zip file, labeled screencast_scripts.zip at my blog. Here is the link---sourcelink

Thanks. Good tempo, I like the human mistakes too. I sometimes end up pausing the video to try out what you're doing in my terminal but since your presentation speed is well paced, I end up typing in my terminal along with you. Note: I'm also using Koans to help complement my online learning.
