Interesting. There was a Dave Cutler in the Mountain View area in the 80s who attended ba.singles events regularly. He had a DEC Vax and a T-1 line in his apartment, but the NT guy does not look like the same one. Looking at the NT guy's timeline, and knowing from working at MSFT his reputation for being difficult to manage, it would have made perfect sense in 1991 (he had been there since 1988) to replace him with a more personable OS guru, which Rashid definitely is.
