5. Sounds as easy as pi.
Just pick a random number and wait. ;-)

8. When I went to the University my Room mate had a Guinness Record
on citing pi orally. I think he did it to a 100 or so digit. I don't really remember.
Anyway his name was in the record

It was right before anyone had a PC


I wonder if this the same guy with other records on a PC?

BTW that's one hell of a PC with 12 cores he's got.

9. IIRC
S Kondo and AJ Yee are the two who set this record. Kondo seems to have a thing for this sort of computation.
