It’s taken a little while but my slide deck from DDD Sydney, 2011 is now up on the web.
Unfortunately I don’t have the code or load test details embedded in the presentation but even so this should still have a number of useful things for you to look at, especially the resources section at the end Smile
Oh, as an experiment, I’ve put both a Slideshare player and a Powerpoint Web App player in this post.  I’d like to know which one you think is better (send me a tweet to @rbanks54 or leave a comment)
