Product Description

A Quarter Century of UNIX presents the history of UNIX. Based on interviews with the key software engineers who invented and built this powerful operating system, this book provides unique insight into the most important operating system in the modern computing environment.

From the Back Cover

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 UNIX is 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.

3.0 out of 5 stars Expensive short chronology; most material is availble online, July 8, 2004

By	Nikolai N Bezroukov "kievite" (Budd Lake, NJ) - See all my reviews

This is an expensive short book with mainly trivial chronological information, 90% of which are freely available on the Internet. As for the history of the first 25 year of Unix it is both incomplete and superficial. Salus is reasonably good as a facts collector (although for a person with his level of access to the Unix pioneers he looks extremely lazy and he essentially missed an opportunity to write a real history, setting for a glossy superficial chronology instead). He probably just felt the market need for such a book and decided to fill the niche.

In my humble opinion Salus lucks real understanding of the technical and social dynamics of Unix development, understanding that can be found, say, in chapter "Twenty Years of Berkeley Unix from AT&T-Owned to Freely Redistributable" in the book "Open Sources: Voices from the Open Source Revolution (O'Reilly, 1999)" (available online). The extended version of this chapter will be published in the second edition of "The Design and Implementation of the 4.4BSD Operating System (Unix and Open Systems Series)" which I highly recommend (I read a preprint at Usenix.)

In any case Kirk McKusick is a real insider, not a former Usenix bureaucrat like Salus. Salus was definitely close to the center of the events; but it is unclear to what extent he understood the events he was close to.

Unix history is a very interesting example how interests of military (DAPRA) shape modern technical projects (not always to the detriment of technical quality, quite opposite in case of Unix) and how DAPRA investment in Unix created completely unforeseen side effect: BSD Unix that later became the first free/open Unix ever (Net2 tape and then Free/Open/NetBSD distributions). Another interesting side of Unix history is that AT&T brass never understood what a jewel they have in hands.

Salus's Usenix position prevented him from touching many bitter conflicts that litter the first 25 years of Unix, including personal conflicts. The reader should be advised that the book represents "official" version of history, and that Salus is, in essence, a court historian, a person whose main task is to put gloss on the events, he is writing about. As far as I understand, Salus never strays from this very safe position.

Actually Unix created a new style of computing, a new way of thinking of how to attack a problem with a computer. This style was essentially the first successful component model in programming. As Frederick P. Brooks Jr (another computer pioneer who early recognized the importance of pipes) noted, the creators of Unix "...attacked the accidental difficulties that result from using individual programs together, by providing integrated libraries, unified file formats, and pipes and filters.". As a non-programmer, in no way Salus is in the position to touch this important side of Unix. The book contains standard and trivial praise for pipes, without understanding of full scope and limitations of this component programming model...

I can also attest that as a historian, Peter Salus can be extremely boring: this July I was unfortunate enough to sit on one of his talks, when he essentially stole from Kirk McKusick more then an hour (out of two scheduled for BSD history section at this year Usenix Technical Conference ) with some paternalistic trivia insulting the intelligence of the Usenix audience, instead of a short 10 min introduction he was expected to give; only after he eventually managed to finish, Kirk McKusick made a really interesting, but necessarily short (he had only 50 minutes left :-) presentation about history of BSD project, which was what this session was about.

5.0 out of 5 stars The coolest book on Unix History, January 6, 2001

By	Santosh Raghavan (Sydney NSW) - See all my reviews

By far the coolest book on Unix!!

The little stories on Unix are amazing.

e.g. Bill Joy's start of BSD distribution or Steve Johnson's lex and yacc development. This book is full of zany characters that we just know names of. This book gives a picture of their personality. The best of the lot are of
Ken T, Dennis R, Robert Morris, Bill Joy, McKusick, and the rest of the looney unix toons. These guys are awesome. A must read for any Unix Lover.

4.0 out of 5 stars Overview of the Unix World, October 25, 2003

By	FePe (Denmark) - See all my reviews

In 1969 the Unix operating system was born. The main developers were Ken Thompson and Dennis Ritchie, two programmers at Bell Telephone Labs. Unix was born because of the cancellation of another operating system developed at BTL, Multics. Learning from the experience they gained from Multics, Thompson and Ritchie began working on Unix, which would later prove to be a good choice. At first they used the PDP-7 machine, assembler language, and the programming language B (by Dennis Ritchie). Only later did BTL upgrade to PDP-11. Because of the upgrade and because of the development of the C programming language, Unix could mature.

The book has six parts: Genesis, Birth of a System, What makes UNIX Unix?, Unix Spreads and Blossoms, The Unix Industry, and The Currents of Change. In the first part, Peter Salus introduces us to Thompson and Ritchie; there's also a chapter on computers in general. Part two, Birth of a System, tells the story about how Unix came to be with what today is seen as much outdated hardware. Later parts give information on the many companies and groups involved in the Unix history, most notably the development of the BSD systems.

Peter Salus has been involved in the Unix history himself, and therefore he writes about it with sympathetic understanding. That means that we don't get introduced properly to the persons. And it means that the pages are full of acronyms. The writing is very compact and full of quotes from interviews, magazines, books and other sources, and that makes the book difficult to read. The book also has some minor errors.

But if you can live with these flaws, "A Quarter Century of Unix" is a good read. It gives an overview of the Unix world, and shows that Linux is just a small part of the whole operating system landscape, and that there are alternatives.
