Jim didn't work on DEC's servers, he was a research scientist known for expertise in data base systems. One of the best technical writers ever, his book on Transaction Processing is one of the bibles of database design and theory. Jim worked at Tandom, IBM, DEC and Microsoft.
One of Jim's projects was Terraserver, the forerunner of Google Earth. Hosting complete satellite image coverage, his group had to buy military spy satellite images from Russia. He also worked with astronomers to develop a unifying database of sky survey images, which was only completed after his death (the World Wide Telescope).
Jim was a great guy, and a great scientist, and his disappearance at sea caused a lot of sadness. Ironically, there was a large effort to search for his boat using online satellite images.
