Should you not see it from timing alone being wrong?
- usrusr 2y agoHad the same thought. But then on the other hand, when nobody is looking at the timing, nobody will see anything. And those who do see a timing artifact, will they really dig deeper or will they just shrug off another oddity? I would not like to bet on another Clifford Stoll in this day and age.
- Tuna-Fish 2y agoRDRAND is very slow and you can fix up the timing with a slowdown loop in the microcode.
