Remember Terra Soft and its Yellow Dog Linux for Power processors? Well, Yellow Dog is no longer the darling Linux for Apple machines since the latter company switched to Intel Core and Xeon processors for its PCs and servers a few years back. And Terra Soft doesn't exist any more, after it was acquired by a Japanese company called Fixstars in November 2008. But Yellow Dog is still digging in the back yard to find a cool spot to lay down, and this time around it's playing with Nvidia's CUDA programming environment for its Tesla family of GPU co-processors.
