Redirecting $stdout to Logger with Ruby on Rails
Ruby on Rails on FastCGI on Apache is a pretty fast and robust combination. Unfortunately FastCGI do doesn’t like output on “standard out”, i.e. $stdout in Ruby. Brian Pontarelli has an article concerning the problem. His suggestion is to simply … Continued
