 Hi

 Kernel#rand(nil) should generate random Float numbers distributed
 uniformly between 0.0 <= x < 1.0.
 But current MacRuby rand() generate obviously non-uniform distributed
 sequence. It NEVER generate a number smaller than 0.1!

 I have wrote a small patch. I check that work fine with AO Bench result
 image.

 Thanks.
