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
