I hate to disagree with all the "it can't be done" mockers here, but IT CAN BE DONE. IBM used to have a program for turning non-tech employees into programmers -- secretaries, factory workers, etc. We even had an accounting manager once. We did it in FOUR MONTHS. It was sixteen weeks, 16 hours a day, 7 days a week. It wasn't all class time, of course, but with the homework and reading assignments every day that's what the time investment boiled down to. Our motto was "Wave goodbye to your friends and families and tell them you'll see them in four months." We actually had several students who rented an apartment and literally moved out of their homes for the duration.
There was no pressure -- every Friday we gave a test, and if you passed it you got to show up on Monday. Otherwise it was back to the assembly line or whatever. We got used to rounding up students from the rest rooms where they had been barfing while waiting for their tests to be graded.
IF AND WHEN they graduated, they were given the EXACT same job as a new college graduate with a 4.0 in CS from MIT, and whoever did a better job got promoted first. I taught this class twice -- well, I taught 1/2 of each class; we had two instructors. That's 15-20 hours of lecture a week from each of us, so the load on the instructors wasn't exactly light, either!
After one class had wound up, I can remember getting a call from a friend who was the manager of a programming department.
"Did you just stick me with this 'Susan Smith'?"
"Yeah. She's great. A real star. What's the problem?"
"Do you have any idea what you did to me? I have to come up with a salary plan for her to triple her salary within a year! You want to try to get that past HR?"
(I lost touch with her about four years later, but 'Susan Smith', ex-minimum-wage employee with a GED, was already making more than I was.)
BTW, we were teaching C, not any of this wimpy new stuff.
If you calculate the hours, in those four months the students actually received a full four years of computer science instruction and homework. They just didn't get any of the history and foreign language and stuff that a college would have made them take.
I will agree that we were cherry-picking intelligent and VERY highly motivated students, but I call BS on anybody who says the job is impossible.
