REST Urls in Rails

A helpful overview of Rails' REST Url convention:

/airports/ + POST = create
/airports/1 + GET = show
/airports/1 + PUT = update
/airports/1 + DELETE = destroy
/airports/ + GET = index
/airports/new + GET = new
/airports/1;edit + GET = edit

Javascript module pattern

A handy javascript pattern from Christian Heilmann (http://www.wait-till-i.com/index.php?p=476):

var revealingModulePattern = function(){  
   var privateVar = 1;  
  
   function privateFunction(){    
      alert('private');  
   };  

   var publicVar = 2;  

   function publicFunction(){    
      anotherPublicFunction();    
   };  

   function anotherPublicFunction(){    
      privateFunction();  
   };  

   function getCurrentState(){
      return 2;  
   };  

   // reveal all things private by assigning public pointers  
   return {    
      init:publicFunction,    
      count:publicVar,    
      increase:anotherPublicFunction,    
      current:getCurrentState()
   }
}();

alert(revealingModulePattern.current) // => 2
revealingModulePattern.init();
