IBM open sources Power chip instruction set

It has been a long time coming, and it might have been better if this had been done a decade ago. But with a big injection of open source spirit from its acquisition of Red Hat, IBM is finally taking the next step and open sourcing the instruction set architecture of its Power family of processors. Opening up architectures that have fallen out of favour seems to be all the rage these days. Good news, of course, but a tad late.
