file systems

I am very surprised that this book is largely get overlooked by Unix society. I read this book for over 2 years, I'm still frequently revisit it. The beautities of the book are 1. The information is up-to-date, a lot of information is summarized from latest Usenix proceedings 2. Topics involved are moderate to advanced, assuming you have enough basic knowledge on Unix Internals, such as those from BACH's book. So it focused on SMP, threaded kernel, virtual file system/journal FS. VM/Fs integration. It fillin the gap for those reader who need to know the progress of current Unixes of current Unixes since mid 80's 3. Solutions and comparisions. The author detailed different solutions on flavour of Unixes, including BSD, SVR4, Solaris (although derived from SVR4), OSF, and the legend MACH. This is the gem of the book, it outlined pro and con of each solution that brodened user's mind. 4. Well balanced contents. The author keep well balance between mechanism and implementaion detail, so that it is detail enough for reader to grasp the essence algorithm but not embroil into topic-irrevalant mess that may distract reader's attention.

This is a fasinating Unix internal book on market that can take the reader into the Unixes forest, in the meantime, keep readers a clear view about the forest evolution and landscape.

The book is not for Unix beginner.

I found Uresh's book very useful and easy to read. I am a processor hardware designer and am reading this book mostly to gain some OS perspectives. I was able to pick up a lot of information that I can apply immediately at work, such as the virtual memory architecture and the interprocess communication sections, etc. This book also contains a very interesting history of UNIX.

I highly recommend this book.

This is the best OS book i have evern seen, really deserve 5+ starts. It gives many design issues/ideas of real exist OSes which helped me greatly. If you are really interested in OS or do some creative design job, this book is a must see. It seems next edition of this book will be unleashed next February. But what i concern is next editon may be delayed, because there are really too much new things these years, Linux 2.6 ... And I hope next edition will have some introduction to Windows Kernel. I am a UNIX fan, but you see, Windows conquer the PC's desktop, it surely has some shining points. GREAT JOB, URESH VAHALIA. :)
