One letter at a time: Quadriplegic coder looks back at 21-year career at Microsoft

A brief but inspiring profile of Greg Smith, a quadriplegic programmer and principal software engineer in Microsoft Research.

This bit was pretty incredible:

He puts together the skeleton of whatever section of code he’s working on that day in his mind. Then, using a camera that responds to his head movements and a mouth-controlled mouse and a metal clicker that he’s been using for 20 years, he’s able to key in the code—letter by letter. It would take too long to type out the code first and then start rearranging. So that part he does by memory.
