Subject: If you have new Macbook Air 11 or 13 inch, do you mind running this to see the speed?

If you can run Ruby 1.9.2 on your Macbook Air 11 or 13 inch.  I can go
to an Apple Store except to install Ruby 1.9.2, I will need a password
to do it...  (actually, maybe I can just copy the binary of the Ruby
executable and use it there...)

p RUBY_VERSION
p RUBY_DESCRIPTION if defined? RUBY_DESCRIPTION
n = 9_999_999
p n

t = 0; 1.upto(n) {|i| t += i if i%3==0 || i%5==0}; p t
