[ale] Losing stability

[Jeff Lightner]

My condolences.  I also did FDA "validation" at a prior job.  It makes
Sarbanes-Oxley seem like a walk in the park.

To prove a systems accuracy you will generally measure four things:

  * True positives - The system says it is so, and the system is correct
  * False positives - The system says it is so, and the system is wrong
  * True negatives - The system says it is not so, and the system is
correct
  * False negatives - The system says it is not so, and the system is
wrong

If RAM failure is the positive condition then memtest86 can be said to
have a high rate of false negatives.  Or so a system auditor might
say.  The company I used to work for was regulated by the FDA.  Any
new software & hardware systems would have to meet certain reliability
requirements defined as above; in other words, a huge pain in the
rear.

Good luck getting your system back up!
