I had the pleasure of reading both the science fiction he and Larry Niven wrote, as well as the Chaos Manor columns in BYTE. The latter taught me a great deal about problem solving in this new era of computing, and it was great to read about actual use cases of the new technologies that were bursting on the scene every few months. He probably ran every networking protocol invented from the early '70s to today, along with all the different wiring standards through his house. He would stick a few different mass storage devices on the network to see which ones actually came close to their marketing hype, and which ones were c**p.
His fiction was good, hard SF - no fantasy stories of witches or unicorns, but an extension of the human race into outer space. The details were clever and believable. I especially remember the scene where a crew discovers how the Moties improved a coffee machine and how it opened the characters' eyes into both the positive and horrifying possibilities of what the creatures could, and eventually did, do to all human technology they came into contact with.
I was (am) willing to overlook his politics, much as I have RAH's. Jerry Pournelle will be missed, and I am sending my condolences to his family.
Thanks, Jerry, for all your insights and creativity!
