I think these two paragraphs sum it up well:
The Defense Independent Pitching Statistic (DIPS) system was invented by Voros McCracken. His studies of pitching statistics suggest that major league pitchers do not differ greatly on their ability to prevent hits on balls in play. The rate at which a pitcher allows hits on balls in play has more to do with defense and luck than to his own skill, and can vary greatly from year to year.

DIPS takes the defense-independent elements of a pitcher's record, places them in a neutral context for park, league and defense, and regresses them to the league average. The result is a translated line of Defense Independent Pitching Statistics, including a DIPS ERA (or dERA); that is, an ERA based on defense-independent pitching performance. Importantly, McCracken found that this dERA correlates better with the following season's ERA than the pitcher's actual ERA does, making it a useful predictive tool.

Basically, DIPS rates a pitcher based on things he can control: strikeouts, walks and home runs. For example, DIPS will favor a pitcher like Curt Schilling (high K rate, low walk rate) over someone like Kirk Rueter (low K rate, relatively high homer rate).

Jay Jaffe has many DIPS-related links on his site, if you're still interested in learning more. There has been much debate on this subject.
