Rails in the real world

"I think Rails is a big part of the problem. Rails is clearly created by a company that will never distribute its software, and the Rails philosophy is again almost pathologically opposed to the idea of turning your software into a package. Imagine trying to make a Rails project LSB compliant -- your database.yaml file would need to be in /etc, your log directory would need to be in /var, and your actual code would need to be in /usr. There went all of your fancy Rails "convention over configuration", and you're suddenly fighting Rails instead of using it, and everyone you ask for help just tells you to "put it in vendor"."

Passenger (mod_rails) in the real world

"Passenger has clearly targeted the shared host market, where hosts have a large memory footprint and a large number of applications. The same strategy doesn’t work quite as well for a small VPS memory footprint and a single application root, where it would make sense to keep an instance in memory at all times (and clean it up and respawn it, perhaps, on occasion if an idle timeout is reached)."
