# Kent Fredric:

(0...8).map{65.+(rand(25)).chr}.join
# I spend too much time golfing.

(0...50).map{ ('a'..'z').to_a[rand(26)] }.join
# For lots of good WTFBBQ factor.

# And one more that's even more confusing, but more flexible and wastes less cycles:
o =  [('a'..'z'),('A'..'Z')].map{|i| i.to_a}.flatten;  
string  =  (0..50).map{ o[rand(o.length)]  }.join;
