I started at IBM in 1964. Worked continuously in development since then, first in System then in Application, later in Web. Many languages, protocols, etc. Retired in 2007 at age 75. Still programming for my own benefit and pleasure. Recently (age 81) I undertook to get fluent in Ruby so I could start sketchup programming. as of now (March 2015) I have become pretty good, but not fluent, but not yet started the sketchup programming. Too many interesting distractions.
