Since the first edition of this book, very little has been introduced in the world of business, scientific, or engineering computing and computer science that was either patently expected or blatantly announced in advance, and perhaps this is a mark of just how developed these dis ciplines have become. Still, the disciplines remain pervasive, and are notoriously segregated into the "open source" and proprietary camps, But the entrenched powers-whether legitimate or licentious-that dominate the business of computing continue to grow, and now reach an incredible level of influence on the distribution, consumption, and assimilation of informa tion in the transnational marketplace. Commensurate with this growth, UNIX and its clones now almost exclusivdy control the service of information giobaUy, and from all indications, this control will not be relinquished in the near future.
