Creating software for work in the world has meant translating into computational models the knowledge and practices of the people who have been doing that work without computers. What people know and do reflects their particular historical experience, which also shapes decisions about what can be automated and how. Software thus involves many histories and a variety of sources to be read in new ways.
History of software, communities of computing

4. , In England, of course, the story has a slightly different trajectory that includes Turing's ACE. Although pursuing his own ideas, Turing knew about the EDVAC report and took it into account. See Alan Turing's Automatic Computer Engine: The Master Codebreaker's Struggle to Build the Modern Computer, B. Jack Copeland ed. Oxford Univ. Press, 2005, Germany offers yet another variant trajectory, originating with Konrad Zuse's machines.

In Calculating a Natural World: Scientists, Engineers, and Computers during the Rise of U.S. Cold War Research (MIT Press, 2007), Atsushi Akera articulates the complex and evolving "ecology of knowledge" among institutions, occupations, organizations, knowledge, and artifacts and actors that constituted that community.

16. U. Hashagen, R. Keil-Slawik, and A. Norberg eds. History of Computing: Software Issues, Springer Verlag, 2002, In my own presentation ("Software as Science—, Science as Software", pp. 25-48) and the ensuing discussion, I missed an important question underlying critiques that I was ignoring the sciences that had contributed to computer science. I saw them—for example, psychology—as ancillary, as resources on which computer science has drawn, but not as constituents of computer science itself. In looking at them in that way, I missed seeing how their application to problems of computation brought out what was computational about them. If computer science is concerned with what can be computed, then it includes the computational aspects of the sciences, and its history includes the process by which those computational aspects were identified, elicited, and articulated.
17. The Forum was announced by Adele Goldberg in a President's Letter in the Comm. ACM, vol. 28, no. 2, 1985, pp. 131-133. The enabling resolution of the ACM Council in October 1984 opened with the statement that "Contrary to the myth that computer systems are infallible, in fact computer systems can and do fail. Consequently the reliability of computer-based systems cannot be taken for granted." (Ibid., p. 131). For a compilation and commentary on the mishaps reported over the first ten years, see P.G. Neumann's Computer-Related Risks, ACM Press, 1995.

31. Indeed, it is striking how many of the languages of HOPL III were initially implemented in C or C++.
