3.0 out of 5 stars mixed, other books are better, May 4, 2005

This review is from: Understanding the Linux Kernel (2nd Edition) (Paperback)

I've been reading kernel books for nearly 20 years -- this is not recommended.

Some of the chapters and explanations I liked, others I felt were dry and lacking. The code examples seem to run through a non-deterministic preprocessor -- the code is supposed to describe 2.4.18, but the code snippets don't quite match the actual code (while generally working the same way, the algorithms/loop structure are often rewritten and the macros are sometimes expanded). I find it very useful when books comment on actual code examples, this is "kinda massaged code" -- I found it very frustrating when I actually looked at the kernel tree when they had snippets in the book.

I often found it necessary to look at the actual code to give more context (but the code rarely matched verbatim -- very strange). And when they did rewrite algorithms, I found the kernel 2.4.18 source to be MORE lucid.

The explanations without code were adequate, and I found some to be illuminating. Perhaps since the book has two authors, different authors wrote different chapters? (I liked some chapters and didn't like others).

If you want a general understanding of how kernels work, Andy Tanenbaum's "Operating Systems: Design and Implementation" where he elaborates on Minix is very useful -- with a complete Minix system (Minix is more of a teaching tool, which it does well, Linus looked at lMinix and wanted a more useful system, hence Linux).

I found Robert Love's "Linux Kernel Development" very good (I read the 1st edition, still need to read the second edtion). And Linux Device Drivers (Corbet and Rubini) is very good and has excellent examples (but the examples may need some work to build on a current kernel -- had this problem with the 2nd edition).

4.0 out of 5 stars GOOD FOR ANYONE INTERESTED IN 'KERNEL 2.4 VERSION', March 23, 2003

By 

reviewer (Zurich, Switzerland.) - See all my reviews

This review is from: Understanding the Linux Kernel (2nd Edition) (Paperback)

Oh yes! This Second of Edition of "Understanding the Linux Kernel" featured a variety of new additions. The most significant being the inclusion of all those attributes, which distinguished the 2.4 kernel version from the 2.2 one.
This new edition also revised some of the staples of its predecessor, like: individual components of data structures, programming pathways, and interdependent algorithms. Its pattern is just as dynamic as that of the First Edition: with expanded elaborations on all those programming and performance tips.
In all, this is a good book to consider, if you are seeking Linux Kernel knowledge. But, if you already own the previous edition, and do not plan to adopt the Kernel 2.4 version, then there is no wisdom in spending on this one.

5.0 out of 5 stars Indepth-coverage of a complex system, August 15, 2003

This review is from: Understanding the Linux Kernel (2nd Edition) (Paperback)

As the title suggests, the author explains concepts
in the linux operating system by using C code.

You need to be able to read C code inorder to understand
the material in the book.

It can get a bit tiring after a while considering that
the author really wants YOU to know LINUX.

The effort is worth it!
