Lately I was configuring a rails project, other developers are in mac OS X and they were using pow [pow.cx]. but I dont have mac but I do have win7 and ubuntu, So some one plz advice me how can I configure it in win7 or in ubuntu. Can I do it using some DNS servers.
A Linux fork for pow is there which you can use here
Hoof is another alternative.
I found Phusion Passenger interesting too.
