My most recent DevX article has just been published. This was fun material to write about because after some experimentation I feel like I have my Ruby on Rails development environment and server deployment strategy just right, at least for my needs. I should mention that although I have been professionally writing Ruby on Rails applications for a few years, I have not yet written an application that will not run nicely on a single server using nginx, memcache, and a few mongrels. I set my development.rb environment for my MacBook and my production.rb environment for the Linux server I am deploying to, and svn is the glue that holds everything together. If you are interested in deploying very large scale applications, my article will not be very useful to you.
