About A Hole In My Head

I am an architect in the Device and Storage Technologies team, focusing on how drivers are developed and how driver developers can develop a quality driver that is stable and performant. Previously (in descending order) I was a developer and technical lead on the KMDF team, architect of the v1.0 Bluetooth stack, and owner of the input stacks. The USB team reported to my manager during the input days so I also have a good working knowledge of the USB core.

Topics will vary a bit, but I am going to stick mostly to writing KMDF and WDM drivers, using a kernel debugger (windbg.exe or kd.exe, not SoftICE!), and my opinions on coding guidelines and design patterns.
