Well, this is a fun little puzzle from Google Blogoscoped

I’ve translated them to Ruby-esque code fragments (with some Rails-isms sprinkled in.)

1. original:

   // idiom 1  
   cop[0].goodInPercent = 100;  
   cop[1].goodInPercent = 0;  

   my version:

   GoodCop=cop[0]  
   BadCop=cop[1]  
   return GoodCop + BadCop  

2. original:

   // idiom 2  
   isCrowd = personCounter >= 3;  

   my version:

   assert (3 == isCrowd)

3. original:

   // idiom 3  
   injury += insult;  

   my version:

   return (insult + injury)

4. // idiom 4  
   1: board.draw();  
   goto 1;  

   my version:

   def Board.back    
     Board.type = 'drawing'  
   end     

5. original:

   // idiom 5  
   if (bird[1].feather == bird[2].feather) {  
       bird[1].flock(bird[2]);  
   }  

   my version:

   flock.collect {|bird| feathers.each {|feather| bird.find_by_feather(feather)}}  

6. original:

   // idiom 6  
   a = getThickness('blood');  
   b = getThickness('water');  
   assert(a > b);  

   Blood.SpecificGravity = 1.0506 # reference: http://www.clinchem.org/cgi/content/abstract/20/5/615    
   Water.SpecificGravity = 1.0000  
   assert (Blood.SpecificGravity > Water.SpecificGravity)
