What is it like to work with Microsoft’s Dave Cutler?

Dave is one of the most inspiring people I worked with (not closely, to be clear). Not only did he lead the team that built a new OS from scratch that was still compatible with DOS-based Windows, with many features on day one that took years to arrive in competitor’s products, he personally designed and coded the portable, multithreading, multiprocessor, secure NT kernel. He was brilliant.
