Today, I finished reading a rather old book. It was published in 1961. It’s about computer programming. So, what can you learn from a 50 year old book? While reading it, I got in touch with one of its authors, Jerry Weinberg. He seemed pretty astonished that even after 50 years someone was still reading one of his earlier works. Besides the fact that the book Computer Programming Fundamentals by Leeds and Weinberg was one of the first books to mention software testing at all, I got many more nuggets of wisdom out of it – astoundingly still valid, even half a century later. I decided to share my insights with others.
