I recently re-read the seminal book by Fred Brooks about software engineering, entitled "The Mythical Man-Month" or MM-M for brevity. Specifically, I read the paper version of the 20th anniversary, which was revised and reprinted in 1995, after the first edition of 1975. I did that on purpose, firstly because it is always a fantastic read, and secondly to understand how much of its contents is still valid today, exactly thirty years later since its last revision.
