I recommend taking advantage of S3's direct-upload feature. This will allow your users to upload straight to your S3 account (in a secure fashion), bypassing the upload to Heroku at all. This keeps your Dynos free to handle normal requests and avoids the high file-upload processing CPU costs as well as memory limit problems.
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.
