I thought Jef Raskin passed away. Apparently he's still talking about commenting code from beyond the grave. The author about box at the end states:

JEF RASKIN, professor of computer science at the University of Chicago, is best known for his book, The Humane Interface (Addison-Wesley, 2000), and for having created the Macintosh project at Apple. He holds many interface patents, consults for companies around the world, and is often called upon as a speaker at conferences, seminars, and universities. His current project, The Humane Environment (http://humane.sourceforge.net/home/index.html), is attracting interest in both the computer science and business worlds.

That's definitely Jef who they don't recoginize as passed. Spooky...
