I sure wish that Bev Harris and others would stop leaning on this
apocryphon. I've seen it increasingly lately, but everyone who knows
something about it knows the claim is false.

What Ken Thompson presented in his ACM Turing Lecture was a theoretical
attack in which a compiler contained a trojan, thus affecting the
programs it compiled. Thompson -did- create a proof-of-concept
internally. But this trojan was never released "into the wild."

And in point of fact, if it had been, it *would* have been detected by
people who do profiling and eyeball machine code. It wouldn't have
been easy to detect, and it wouldn't have happened right away. But it
sure as heck wouldn't have gone 15 years. Thompson's point is very
important enough by itself, let's not invent make-believe stories about

If I didn't already know a lot about the voting issues, I might have
read Harris' note, noticed the silly falsehood about Thompson, and
assumed the rest was of similar quality (i.e. conspiratorial ranting).
That would be a mistake... but one that is compelling without prior

No, no, no! This was not a "compromise" in the way claimed. It was a
bug that never made it into the kernel trunk. More wrongheaded

It's bad enough that Harris is discrediting herself with falsehoods (or
half-truths, at best) and insinuations, let's not taint OVC with this
kind of brush.
