Accounting For Developers, Part I
When I went to school for an AAA in Computer Programming in 1989-90, a quarter of accounting was required for graduation. The instructor didn't like computers (which was the reason about half the class was there), and tried his best to convince everyone they needed to major in accounting, but he was a good teacher and I learned a lot of stuff, none of which I've needed over the last 30+ years but all of which I was glad I learned.
