I'll be at the N9 Hackathon this weekend in Vienna. Sunday morning (October 9th) at 10am, I'll give a presentation about Woodchuck. I'll talk a bit about Woodchuck's motivation and a fair amount about Woodchuck's architecture as well as what we hope to learn from the user study and how we planning on using it to evaluate different scheduling algorithms. If you are around, you should come by!
