I'm not really all that mysterious

serious geekery revisited

I just ran into this old post about idioms rewritten in computer (pseudo)code. It occurs to me that I’ve learned a lot more Ruby since then, and I decided to rewrite some of the pseudocode into actual code.

  1. original:
    // idiom 1  
    
    cop[0].goodInPercent = 100;  
    cop[1].goodInPercent = 0;  
    my version:
    class Interrogation  
    
      @Interrogators=[]  
      
      def GoodCopBadCop  
        @Interrogators=[cops.select { |cop| cop.is_good? }.first, cops.select { |cop| cop.is_bad? }.first]  
        cops.delete(cops.select { |cop| cop.is_good? }.first)  
      end  
    end  
  2. original:
    // idiom 2  
    
    isCrowd = personCounter >= 3;
    my version:
    class Fixnum  
      def is_crowd?  
        self > 2  
      end  
    end  
    
    3.is_crowd?
  3. original:
    // idiom 3  
    
    injury += insult;
    my version:
    return (insult + injury)
  4. original:
    // idiom 4  
    1: board.draw();  
    goto 1;
    my version:
    session[:return_to] ||= 'http://http://mahiwaga.pw/drawing-board'  
    redirect_to session.delete(:return_to)
  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);  
    class Liquid  
      attr_accessor :spec_grav  
    
      def initialize args  
    	 args.each do |k,v|  
    	   instance_variable_set("@#{k}", v) unless v.nil?  
    	 end  
      end  
      
      def is_thicker_than?(other_liquid)  
        self.spec_grav > other_liquid.spec_grav  
      end  
    end  
    
    blood = Liquid.new(:spec_grav => 1.0506) # reference: http://www.clinchem.org/cgi/content/abstract/20/5/615  
    
    
    water = Liquid.new(:spec_grav => 1.0000)  
      
    blood.is_thicker_than?(water)
