  • That looks like the place where

    One summer weekend in 1989, Arthur Whitney visited Ken Iverson at Kiln Farm and produced—on one page and in one afternoon—an interpreter fragment on the AT&T 3B1 computer. I studied this interpreter for about a week for its organization and programming style; and on Sunday, August 27, 1989, at about four o’clock in the afternoon, wrote the first line of code that became the implementation described in this document.

    An Implementation of J, Appendix A: Incunabulum.

    This is British Columbia, where my extended family on my father’s side all moved together to escape the harsh Alberta winters.

    Ironically, my father, like the Iversons, has acquired an Ontario farm.

    Ah… 1989, Michael S Montalbano dies and J is born.

  • I can tell you that the barns in the photo strongly resemble those at Kiln Farm. (Where there are also horses.)

    That’s a nice co-incidence. I’m thinking about a photo of Ken holding a J Frisbee on that farm.

    Yes! I do! I shall embed it later when I’m on a work horse computer – right now I’m in Ottawa at the Public Services Building at Gilmour & Metcalf on my iPad!

    (Photo by Jana Michaud is of Dr Iverson on his farm in Ontario, with a Frisbee bearing the logo of J, APL’s daughter programming language).
