Well, I write C++ with a FORTRAN accent. :) I'm one of two old codgers in the department that can even read FORTRAN. The other guy got roped into a big project in another division where they are upgrading and verifying a bunch of FORTRAN code, some of it written before the flood I think.
I've still got my old slide rules, well two of them anyway. I actually generally used a cheap plastic mini rule for coursework, it was easier to haul around, even though I had both a K&E metal and some Japanese brand of bamboo slide rules. I was out of college, and had 12 hours of grad credit, before I bought my first TI calculator, at the base exchange. The price had dropped enough by then that the powers that be no longer considered them "office equipment", which the BX could not sell.
