What happens when coding stick meets coding_pad? It’s been well over 25 years that I wrote any assembler code. But I ran across this pad of coding sheets in a closet and I had this urge to use it. Of course I don’t have a mainframe to test it, but it can’t be wrong. Can it?Continue reading “Hello World in 370 Assembler”
What good is a coding stick without a coding pad? It’s hard for many to conceive of a time when computers were programmed by people with only pencils and paper, sitting at mostly empty desks with no distractions, other than the window and the clock on the wall. So how did that work?Continue reading “Coding Pad”
Punched cards have been around for far longer than computers have. The earliest form that I am aware of is the Jacquard Machine (circa 1800) to control a loom. Charles Babbage incorporated the idea into his Analytical Engine (circa 1837). Herman Hollerith designed tabulating machines around the concept and saved the 1890 US Census. His design and company evolved to become the IBM Corporation. This is the card of which I speak…Continue reading “Punch Card”
I started coding back when the mainframes were all steam powered. To maintain productivity, we took turns shoveling coal into the furnace. This worked well enough in the mornings but afternoons there was always someone who had one drink too many for lunch and wound up shoveling the coal into the ash bucket. We’d be down for a half hour or so. We all learned to juggle (seriously) in order to preserve sanity in the down times. At one point a bunch of us group-ordered a set of custom made 2 pound juggling bags using lead shot for weight. They were awesome for blowing off steam. But these days, nothing ever goes down (lol). My how technology has changed! Do you know any programmers these days who juggle?
