Confreaks have posted the talks from this year's Ruby Hoedown. Of special interest to me was Joe Kutner's talk on Ruleby, the Rule Engine for Ruby.
A question from the crowd asked about if there were plans for an external DSL and the answer is "yes". We are building an external DSL based on the internal String based DSL in Ruleby with parsing handled by Treetop. It has been a while in the making or not making, but work has begun again...
