Wading through lame crap, plus on-topic privacy stuff

[Simon Spero]

Even your on-topic stuff wasn't really on-topic "-)

You can relax - the bank doesn't have a bunch of PIs snooping around to 
find out what you're up to. What actually happens is that the university 
sells the list of registered students to various organisations for use in 
direct-mail campaigns. 


(defun modexpt (x y n)  "computes (x^y) mod n"
  (cond ((= y 0) 1) 	((= y 1) (mod x n))
	((evenp y) (mod (expt (modexpt x (/ y 2) n) 2) n))
	(t (mod (* x (modexpt x (1- y) n)) n))))
