Be that as it may, with all that Peter wrote in the last 24 hours I tend to 
weigh his expertise a bit less than I did before.  YMMV, but his descriptions 
of his data center do not instill a very high confidence, do they ?

While it may be true that genius math people may make lousy server admins (and 
vice versa), when I read someone claiming there are random undetected errors 
propagating through raid, yet this person cannot even regulate his own 
"random, undetected" power supply problems, then I start to wonder.  

Would you believe that at one point, for a minute I wondered whether Peter was 
actually a troll ?  (yeah, sorry for that, but it happened...)
So no, he apparently is employed at a Spanish university, and he even has a 
Freshmeat project entry, something to do with raid...  

So I'm left with a blank stare, trying to figure out what to make of it.
