I feel like I knew James well, because his on-line personality was so true to his own self. But we only had dinner together about three times over the years, when I went to SF to visit my daughter (Duke '95). He was a polymath -- knew a lot about everything. In fact, given his frequent writings showing off his knowledge of science and math and lots of other stuff, I looked forward to catching him in a mistake, but it didn't happen often.
He was a published expert on Unix and was hired for this expertise, first by Twitter, and then by Snowflake. He was among the first 20 employees. He was on the screen during the fabulously successful IPO -- a bearded and regal presence, giving the "royal wave."
After departing DBR post-LAX, he set up a list serve that I was pleased to participate in, along with Jason Evans, Jim3K, -jk and other participants on this Board. Although we frequently argued, we were a very loyal band of correspondents. He was extremely open about his various physical ailments, and so we were well-informed on his condition, but he seemed to keep plugging along.
He will be sorely missed by me and many others.
