Highly recommended: "5 Things SQL Server does different from what many developers expect" by Nico Jacobs
A couple of weeks ago, the Belgian Techdays were held in Antwerp. Together with Scott Hillier I presented the SharePoint pre-conference sessions (watch them online over here, search for pre-conference or SharePoint). Even though Belgium is not a very big country, the Microsoft team managed to get some high profile speakers like Anders Hejlsberg and Scott Hanselman. But if you have like 60 minutes to spare there is one session that I'd really recommend to check out, not related to SharePoint, but very interesting and entertaining nonetheless: 5 Things SQL Server does different from what many developers expect by my U2U colleague Nico Jacobs. Nico did a fantastic job, so sit back and enjoy! :-)
