I'm getting settled into working for Microsoft again - it's basically like drinking from a firehose.
I am also still hard at work on the book chapter for the upcoming SQL Internals series.
FYI I believe Paul and Kimberly still plan to host the content I posted here, so you can reference without worry.
Thanks,
Conor
