A guy that is 69 and started out writing COBOL in the late 1970's on an HP-3000 in school.
Later worked on DEC servers, then DEC Alpha (early RISC) and HP-9000
Then SGI IRIX on Indy's and Inidgo's
presently migrating from an Apple X-Serve into a new modern experience... these things are always a test
