What's this?

  1.  'end' is missing.
  2.  'if ... then false else true end' is a lot of hot air
      around 'not ...'.
  3.  As a side effect the method changes the current
      directory.

Say

  def dir_empty? path_to_dir
    Dir.chdir path_to_dir do
      not Dir.glob('*').length > 0
    end
  end

Then, you may consider hidden files ...

First think, then write. Sorry!

Bertram
