    @mattblaze I'm unfamiliar with him/his work; could you maybe provide a tiny summary or pointer to his confrontations with unreliability? That sounds like an interesting topic

      I cannot do his memory and legacy justice here, but I will say that his work (and friendship and support) influenced almost everything I've worked on. He was one of the first computer scientists to confront (well before it was popular to do so) the fact that computers and software are unreliable in both theory and practice.

        Had a few things published in RISKS in a former life.

          @mattblaze I felt so strongly when a feature I implemented was featured in the risks digest! (We emailed forgotten password in plaintext back to the user; it was the 90s!) I loved reading that and his authoritative assessment of it all.

            @mattblaze comp.risks came as a revelation to me when I first stumbled onto the listserv in 1989.

            @cstross @mattblaze I was working mainly DoD stuff then and loved all talk of digitizing the up to then mostly analog systems. Many of the issues was all the analog safety feedback mechanisms not being implemented at all in the digital controllers.

              @mattblaze Peter will be missed. BTW, for some years, I worked in the same building as Peter, but in a different group. He was always pleasant and, of course, highly competent.

                @mattblaze I subscribed to his RISKS forum back in the early 80s (yes, I am old).

                            @davebiff @mattblaze Peter once told us about an incident where an X-ray machine killed a patient. Its snazzy GUI got a lot of testing for sequences of inputs, but when used by a technician, the inputs came in much faster. There was a race condition resulting in an inappropriate configuration. Peter mentioned the lack of sanity checks - the patient complained about feeling warm and the technician ignored that, passing it off as babbling.

                              RISKS Digest was most likely my initial exposure to IT security, back in the late 80s.
                              What a legend.
