Great book on BSD 4.4, but make sure you've read Bach first

While this book has been written by some of the best in the UNIX arena, their strong focus on packing a lot of content into these pages at times can prove a burden to the reader. Reading through the chapters, it appears that the book could have been rendered more readable if a knowledgeable technical editor had put the finishing touches on it.Nevertheless, even though it takes a bit of time to get used to the different writing styles and differences in quality of several chapters, this books is a well of insights into the internal workings of BSD 4.4 and its derivatives (like Mac OS X).In order to gain the most from this title, I strongly urge interested readers to already have worked their way through Maurice J. Bach's "The Design of the UNIX Operating System".

Don't get confused by the cover, it's not a comix book :)

Seriously, despite of the funny little daemon on the cover, this book is quite difficult.First, it's a technical book about the BSD kernel. The only reason why you would want to read it is that you really want to know How It Works(tm). It's all about kernel. The drivers are only slightly touched, the API is touched even less. Rather than that, this book shows you the fields and flags of internal structures and the ways they are handled. Therefore I'd only recommend it to the system programmers and may be to the enthusiastic admins.Second, certain chapters are written much worse than the others. The language in chapters 4 (Process Management) and 5 (Memory Management) is sort of a tangled making reading a challenge and it's really a pity because these two topics would better be covered best.Also note that this book does not include sample code AT ALL. All the principles and algorithms are described using plain English and I'd say it's great, because it's much easier to follow, rather than making your way through somebody else's C scribbling.Anyway, 5 stars, because it gives you 500 pages of pure distilled info. And it's info from the authors of BSD !I'm definetely looking forward to read this book again and this is one of the books that are worth it.

Rigorous, but worth the effort

Okay, I'll be the first to admit that I am not a kernel hacker by any means. I can't even program my way out of a wet paper bag (a bit of an exaggeration, but you get the idea). However, as a sysadmin, I firmly believe that you should have a solid understanding of whatever OS platform that you are working on. For me, that would be Solaris and Linux. So why am I recommending a BSD book? Well, BSD has a rich heritage in UNIX. It was the first UNIX to incorporate TCP/IP and it gave us sockets, FFS, and a rich set of tools (csh). FreeBSD, the most well-known of the *BSD family, powers some of the largest sites in the world (e.g., yahoo). It is an extremely robust and stable Operating System. It is also much more elegant than Linux. This book is the ultimate BSD bible. It is written by some of the Gods of BSD and is extremely rigorous. I've made my way through this book twice and I've learned something new each time. If you put the effort into this book, you will come out with a greater understanding of UNIX in general. If you are a BSD hacker, then you should already have this book. This is a hard read, but it is really worth your time and effort to read this book at least once.

Great book for the theories behind 4.4 BSD

Although the book isn't technically rigorous like Tanenbaum's book, D & I of 4.4BSD does an excellent job of explaining processes, memory, I/O, IPC etc with regards to BSD. The text is sprinkled with snippets of code where examples are needed. I especially recommend this book to College students, as it is relatively easy to comprehend, compared to others I have read.

Invaluable documentation of an important Unix implementation

I'm shocked that no one has reviewed this book yet. This is it, one of the top books ever written documenting a version of the Unix kernel. If you are interested in kernel design, you probably already have this book on your shelf. If you haven't worked through it yet, you have a real treat ahead of you. One thing that makes this book more exciting than some of the other books on unix kernel design, such as Bach's venerable tome or _Magic Garden Explained_ , is that the source code is available for closely related, modern systems -- FreeeBSD, NetBSD, and OpenBSD.
