A Quarter Century of UNIX
On June 12, 1972, Ken Thompson and Dennis Ritchie wrote, "the number of  UNIX installations has grown to 10, with more expected." Two years later  the number was 50. It is estimated that there are over 3 million UNIX  systems in operation today ...UNIX is a software system that is simple, elegant, portable, and  powerful. It grew in popularity without the benefit of a large marketing  organization. Programmers kept using it; big companies kept fighting it.  After a decade, it was clear that the users had won.A Quarter Century  of UNIXis the first book to explain this incredible success, using  the words of its creators, developers, and users to illustrate how the  sociology of a technical group can overwhelm the intent of  multi-billion-dollar corporations. In preparing to write this book, Peter  Salus interviewed over 100 of these key figures and gathered relevant  information from Australia to Austria. This is the book that turns UNIX  folklore into UNIX history.The book provides the first documented history of the development of the  UNIX operating system, includes interviews with over 100 key figures in  the UNIX community, contains classic photos and illustrations, and  explains why UNIX succeeded.0201547775B04062001
