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.

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

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.

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.

Many of the issues was all the analog safety feedback mechanisms not being implemented at all in the digital controllers.

(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.

I think reading some will give you an idea. I recall an election result off by 4096 (or some power of 2) votes. I read comp.risks off and on for years, then decided to stop as I was having vague nightmares.
