They grafted the implants directly into the bone and fused the skin around them. When are we going to see this technology come to human prosthetics? If I lose my arm in a car accident, I don't want a fake arm attached to my stump with a suction cup, I want a universal mount embedded in what is left of my arm bones! I want to be able to adapt the attachments for whatever job I need (hand, grinder, chainsaw, soldering iron) using a quick release mechanism.
I installed Deep Freeze on my parent's computer years ago after they proved themselves unable to handle the responsibility of a computer. It turned out to be a godsend and took much of the burden off of both of us. They no longer fear damaging their computer with their ignorance - they are one reboot away from a fresh machine, and I no longer fear their phone calls.
Deep freeze is extra handy in that it doesn't stop them from using their computer; it just resets it back to "factory" condition each time they reboot. All the windows functionality remains and it stays out of the way. If they really need to make a permanent change, they just have to reboot in defrost mode.
I spent years futilely trying to teach my parents to safely use a computer. But since I couldn't take the knife away from them, I could only make sure it wasn't sharp enough to hurt anybody.
