Longtime computer columnist and science fiction author Jerry Pournelle died on Sept 8, 2017. I count Dr. Pournelle as one of my influences.
I was never a big sci-fi fan, so I’ve never read any of his novels. I really enjoyed his computer journalism, however. He was a tech curmudgeon, and he was blunt, but frequently that was what we needed, especially in those early years when computers didn’t work as well as they do today.
