Just moments ago, I got my first email from Mark Zbikowski. What an honor! (OK, so it was just a request to pass something along to some folks at my previous company.) Nonetheless, it was a small thrill to see the name in my inbox.
If you don't know who Mark is, try opening up any DOS, OS/2 or Windows executable in a hex editor and look at the first two bytes. Or check this link out.
