@AtanasE @SwiftOnSecurity My first encounter with computer technology was seeing the sealed computer room in the insurance company where I worked in 1969. But my first actual interaction with computers was the mainframe at the University of Colorado, Denver, in 1975, using punch cards and Fortran to run statistical analyses. My first personal computer was a Kaypro II running CP/M, on which I wrote my doctoral dissertation in 1983-1986.
