My first katacast

After seeing some of the great examples of coders working on practiced problems on KataCasts, I decided to try make my own. I am not happy with the pacing of the video. I’m about a minute too early relative to the music.

But I thought I’d post the video here, to see what you all think. Comments are welcome!

I hope the video will demonstrate how to use refactoring effectively to drive the design of a program.

I chose the FizzBuzz kata – that is, to generate a sequence of numbers where every number divisible by three is replaced by “fizz” and every number divisible by five is replaced by “five”. The music changes to be more aggressive just as I induce a new requirement into the kata: The FizzBuzz generator should be programmable, so, in the kata, numbers divisible by two are replaced by “coconut” and numbers divisible by seven are replaced by “banana”.

Thanks to Emily Bache for the inspiration for the kata.

The video was made with IntelliJ IDEA Community Edition on Windows Vista (!) with BB FlashBack Express (free screen recorder), converted to AVI with Windows Media 1 codec and uploaded to Vimeo.
