I was just thinking about the part just after your quote in that paper. Where he is talking about trusting compilers, and hardware, etc... What if we can't trust the compilers all our software was made with? Simple, disassemble the code and make sure the instructions coincide with what you programmed. How can you trust the disassembler? etc... Stupid really, but something to think about. I didn't read much of that part, so I probably missed where he mentions that it is silly to worry about that type of stuff. I'm too focused on the small things. I guess that's just the way I am.
