This is totally random. Really - this is all about random. We've got a new technology, code-named Bull Mountain, that lets you generate random numbers with the help of our processor. Bull Mountain is an innovative hardware approach to high-quality, high-performance entropy and random number generation, comprised of a new Intel® 64 Architecture instruction RdRand and an underlying Digital Random Number Generator (DRNG) hardware implementation. There are lots of great advantages to this method of RNG – too many to list here. But if you want to learn more about what this exciting technology can do for your software, take a read of the recently posted technical article "Download the Latest Bull Mountain Software Implementation Guide". The link will take you to a page where you can get the guide as well as code samples.
