I think there may be a problem with the gateway again.. 

The problem you have is that myhash is local to stuff.rb and
will not be made available if you #require or #load the file.
Instead, you have a few options: either make myhash a constant
(MY_HASH), a global ($my_hash) or set up a method to retrieve
it (def my_hash(); ...; end) and call the method from your
main file.
