Here's a little pick me up for Saturday morning; you may not need coffee anymore after reading. A vast number of Xerox scanners introduce hard to detect errors in the "copy" by switching numbers and characters with similar.

I read this in some unrelated thread after my first coffee and it gave me a cold sweat.

@markdennehy the specific problem he highlighted with architectural plans? Every copy no matter how produced has to be stamped and signed by an architect. Can you imagine being that architect and realising you may have unwittingly produced incorrect copies, that are now archived in some planning office FOREVER.

I would never sleep again.

@jjcelery Forget the architect, day one, lecture one of engineering was 30 seconds of "congrats on passing the leaving cert" and then an hour of "here are all the ways engineers have killed people through professional negligence" and some of those were like the Hyatt walkway collapse where the builder ignored the blueprints and it was still the engineers fault. And that was with _correct_ blueprints. Holy shit, if you had signed off on stuff for 20 years with dodgy photocopies, how many lives?

@markdennehy these are of course the extreme examples, but I was going for "ordinary", ie even an ordinary person would never sleep again, nevermind those who signed off on life-impacting documents 😬

@jjcelery Oh, definitely. Did you really sign your mortgage documents, are your land registry entries actually correct, are you really married/divorced on the terms you thought you were, what's your kid's actual name, etc, etc, etc.
The amount of havoc random character changes can cause is crazy.
It's just that Prof Perry left a few of us with engineer PTSD so our heads go to the same place first :D

@markdennehy I think that's an appropriate amount of horror fear to feel for any engineer 😂 I just wish more people in software felt this this same amount of mortification

@jjcelery I remain perpetually shocked when I see how rare it is in the flesh :(
