I'd like to sort collections randomly. This is what I tried first:

my_array.sort { |a,b| rand(2) }
>

but the results weren't very random. I then tried the following:

class Array
>   def random_copy
>     b =3D Array.new
>     while b.length < self.length
>       random_value =3D self[rand self.length]
>       b.push random_value unless b.include? random_value
>     end
>     b
>   end
> end



This works but I'm sure there's some Ruby magic for doing this better.

thanks
