Welcome back to a new term of The Morning Paper! [2] He has also been in the forefront of those urging the professionalization of "software engineering" (a term that he characterizes as "an unconsummated marriage"). The primary argument of Parnas’ paper, besides for modularization of systems, is that we must implement a concept called “Information Hiding” and the explanation of what that means. Frederick Phillips "Fred" Brooks Jr. is an American computer architect, software engineer, and computer scientist, best known for managing the development of IBM's System/360 family of computers and the OS/360 software support package, then later writing candidly about the process in his seminal book The Mythical Man-Month.
