Quote of the day, on Intel i7 series of processors with 6 cores and hyperthreading:
"You have six with six brain damaged cousins.
And sometimes you can hand a cousine: here eat this while I'm doing the real work, and everything is fine.
But once in a while he chokes. And then the brother actually has to pad him on the back to get it cleaned up."
