<p>Dr. Crispin Cowan, famous Linux security guy and vocal Microsoft critic, now works at Microsoft. What? Has Hell opened a ski resort? This talk will reflect on my first year at Microsoft as a Linux guy. Hell has not frozen over, and I'm having a great time. I will talk about how the Linux and Windows communities are more similar to each other than either community cares to admit, for good and bad, as well as highlighting the differences that I have found. I will also highlight the similarities and differences in the security problems faced by Windows and Linux.</p>
