After so many years with AVR and ARM (and also some esoteric archs), I forgot how much pain it is to RE PICs.

My university professor on electronics 101 is always told us that "electronics is a science about contacts". I was totally disagree with him when I was young, but it looks like he was right from the beginning.
Just 'fixed' the dishwasher. Disconnected it, pulled it out, tipped it over, looked at it, gave up, and put it back. Now it works. Flashback to childhood. Ppl thought I was a wizard at fixing electronics, but 90% of the time I just opened them, blew dust out & then they worked.

I remember one ICS gateway that avoided RCE because HTTP library in their firmware was too old and didn't have memory corruption from the newer versions. ICS is the best sometimes.
“Yes we have SolarWinds but we haven’t updated it in a long time, well before their compromise.” . I love the ICS community.
