[ale] Fun with Slink!!

[Jim Kinney]

Bumblebee is way slick! I have a much new $$$ dell xps15 with nvidia and Intel. Being able to not run the powerhog just watchin utube vids splaining how to screw up a metal lathe is sweet. Then fire up a gpu project with cuda code launched from cli and listen to fan ramp up to take off speed :-)

The bee is better than the winders stuff. It's flat powered off in Linux. In winders, it trickles power waiting to ramp up fast as an automatic overload gpu.

Or I can watch metal shop utube while cashing out with bitcoin mining on the gpu.
