title: Any sites which help write more optimal Ruby code?
body: <p>I've just started writing Ruby code from a C++ background.  When I write the code, I find myself writing C++ code using the Ruby keywords(using while and for loops when a single Ruby command will make the code much shorter).  Are there any sites which you use where people can look at code and recommend more optimal ways to use the language?  For me its Ruby specific, but I'm sure this would apply for anyone transitioning to a new language.</p>
