• You Had Me At EHLO… : Should You Virtualize Your Exchange 2007 SP1 Environment? – With the release of Microsoft Windows Server 2008 with Hyper-V and Microsoft Hyper-V Server 2008, a virtualized Exchange 2007 SP1 server is no longer restricted to the realm of the lab; it can be deployed in a production environment and receive full support from Microsoft. This past August, we published our support policies and recommendations for virtualizing Exchange, but many people have asked us to go beyond that guidance and weigh-in on the more philosophical question: is virtualization is a good idea when it comes to Exchange?
• Future-Proofing A Design – Designing code to be future-proof without a clear understanding of what the future holds often leads to excess generality; generality has very real costs, and they might be higher than the benefit accrued.
  Design your code to solve the well-understood problem. If you design it to solve an unknown future problem, odds are good that you're going to solve it poorly, making even more work for the future.
