I'm back in action at last, so it's time for another Friday Q&A. This week, both someone named "charles" and Brian Olsen have suggested that I talk about OpenCL, so I'm going to go through the basics of what OpenCL is and how to do some simple computation with it.

As you saw from my last post, I was sorely disappointed in this year's WWDC keynote. Fortunately the rest of the week didn't follow the same trend.
