I got a good taste of how far out of date I was when I referred to a "do loop" to explain an issue to our IT guy and he had no idea what the heck I was talking about...

the original "debugging" a computer meant removing the dead bug from the guts of the machine.

in college we were cutting edge because some of our buildings had terminals connected to the mainframe... so we didn't have to write out our code onto sheets of data entry forms for the key puch operators to turn into Hollerith cards that were manually feed into the fool thing. And print out reams of computer paper... if you didn't mess up you code.

now we have cloud storage & god knows what next.
