Array review and Enumerable usage

February 24th, 2008 |

The Array class (as well as others) includes the Enumerable module (http://www.ruby-doc.org/core/classes/Enumerable.html). It provides a lot of power when dealing with collections. Great stuff. Please review the array functionality as well as the cool things you can do because of the methods in Enumerable.

Update – I just ran into an article that writes about this topic: http://www.rubyfleebie.com/life-beyond-the-each-iterator/

Change to Syllabus

February 13th, 2008 |

I’ve decided to remove RSpec from the course outline. I wish we had more time to cover it because it is an amazing tool for programming. The whole Behavior Driven Development movement is really awesome. Fortunately, you should get RSpec covered in CIS 272 Agile Software Development. I feel we need to leave enough time to cover what is left in the course outline. Thus the next topic of study is ‘sorting and filtering’. Specifically, sort_by, comparable aka “spaceship operator”, and using the cool methods in the Enumerable module.

quote from Tom Capaul’s email:

Due to all the missed days of school this week thanks to the snow, I am not going to be ready for the contest on Saturday, Feb. 9, so I am postponing it until March 1. Hope you can make it then. I apologize for any inconvenience this causes. Please feel free to contact me if you have any questions.
