Speaking of DSL Tools, Software Factories co-author Jack Greenfield just started blogging. He has jumped into the running debate between IBM's Grady Booch and a variety of MS folks including Steve, Alan and myself. He does a good job summarizing the argument including pointing out where he and Booch agree:

In particular, we share the conviction that packaging knowledge for reuse in patterns, languages, frameworks, tools and other form factors is “the right next stage in cutting the Gordian knot of software”.

Jack rightly points out that while we all agree on these mechanisms for packaging knowledge that the devil is in the details. I look forward to seeing more on these details from Jack in the future.
