Samples of recent work for various problem types - the main languages I work with are PHP, JavaScript, Java, SQL, VBScript, and Ruby in that order.
I will be adding more samples to this repository as I organize my code.
There are other specs I've coded with, but if I don't believe that I did anything non-standard with those, I did not add those to this repository (bash scripts, JSPs, Groovy on Grails, basic wrapper classes, etc).
