This page is for students and instructors who have too much time on their hands. It is an offshoot of Googlewhacking, the sport of finding English-word pairs that appear together (adjacent) in one and only one place on the web, as verified by searching Google. See for a complete description of the rules and other useful information.

In the DDPP version (Digital Whacking?), you are to find an English-word pair that appears nowhere on the web, and appears exactly once in DDPP3e in the main text, a heading or a caption (anything except inside a figure or table body).

Write to me with your discoveries, including the word pair, the DDPP 3rd-edition page on which it appears, and your name. I will verify submissions manually (I don't expect too many). The first ten successful whacks will be posted on this page. Once Google re-indexes this page, you can go to the Googlewhacking page if you wish to submit your entry which now appears exactly once, before anyone else discovers it.

For example, the heading "comparing comparators" appears on page 426, as found by John Wakerly on July 2, 2002.

Reader submissions:

The word pair "nondeterministically settling" appears on page 534, as found by John Kremer on August 24, 2002.

The word pair "more diss'ed" appears on page 139, as found by Derek Schuff on November 9, 2002.

The word pair "shifty circuit" appears on page 604, as found by Scott Dunston on November 11, 2002.

The word pair "transitions ooze" appears on page 128, as found by Bruce Howell II on September 5, 2003.

The word pair "judiciously redrawing" appears on page 213, as found by Dominic Babineaux on March 2, 2005.

Unfortunately, all of these submissions, including my own, break one of the official rules: Don't use quote marks within your query! The whacks above give (or at one time gave) zero or one hits only when submitted to Google enclosed in quote marks.

One other reader, Greg Sutton, submitted "inverted 1-out-of-n code" on page 55 but that's not a word pair.

Reader Don Wunsch pointed out that there are lots of unique word pairs that appear on succesive lines of the index, such as "transistor Schwarzenegger" and "fuse Seidensticker" on p. 940. But that hardly seems interesting or fair.

Finally, the rules now preclude any whacks that appear on a page that mentions Googlewhacking. So, I guess this whole fame-making scheme is a flop! But then, DDPP does talk about flops a lot....
