Looking at http://github.com/rackspace/php-cloudfiles/blob/master/cloudfiles.php at the function _guess_content_type() it's looking for the Content-type and it's not finding it. Either you need to add more information to your /share/magic or you can probably set the Content-type before calling the load_from_filename if you know what the content type is.
Here's a fix if you have neither mime or FileInfo functions available.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
