Openstack Hello World?

You need to be more clear when you say 'write a program on an Openstack cloud'.

I made a research on your question, Look at the API functions here i.e. Object api, compute api etc apis, without these functionality getting finished, all the openstack is you cannot code anything programming wise. Anything you do is only you build a cloud and execute commands manually.

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.
