If you don't know what "9-edge face down" means, you don't know. . . .

If you never walked into a computer room and had to scream over the sound of blower fans and line printers, you don't know. . .

All the sciences used Fortran (FORmula TRANslation) , but COBOL (COmmon Business Oriented Language) was the language that built business. Anyone know what the acronym ASCII stands for off the top of your head? I just say that I'm old enough to know all those things and remember the time when you really needed to know them to do anything with computers. Today, you just touch the screen and drag icons around to do work. We've gone from being pencil pushers to picture pushers.
BTW: Remember serial port printers? I talking about the old serial ports. In some ways, the printers have come full circle from serial to parallel and back to serial (USB) again. However, I love my wireless (WIFI) printer, an Epson Artisan 837. It has been very robust ever since I installed it. I guess you could really say we've come full circle from writing with a feather quill to inkjet printers that spray ink onto the page. All that laser stuff and toner mess was just a bump in the road.
