Dozens of detailed programming examples are shown, drawn from contemporary application areas such as system administration, networking, web development, databases, finance, HTML, CGI, and text analysis.

Most books on operating systems deal with theory while ignoring practice. While the usual principles are covered in detail, the book describes a small, but real UNIX-like operating system: MINIX. The book demonstrates how it works while illustrating the principles behind it. Operating Systems: Design and Implementation Second Edition provides the MINIX source code. The relevant selections of the MINIX code are described in detail. When it first came out, MINIX caused something of a revolution. Within weeks, it had its own newsgroup on USENET, with 40,000 people. Most wanted to make MINIX bigger and fancier. Instead, Linux was created. That has become quite popular, very large, and complicated. MINIX, on the other hand, has remained small and suitable for instruction and example. The book has been revised to include updates in MINIX, which started out as a v 7 unix clone for a floppy-disk only 8088. It is now aimed at 386, 486, and pentium machines and is based on the international posix standard instead of on v7. There are now also versions of MINIX for the Macintosh and SPARC available. Professional programmers will find this book to be a valuable resource and reference book.

If you’re one of the many Unix developers drawn to Mac OS X for its Unix core, you’ll find yourself in surprisingly unfamiliar territory. Unix and Mac OS X are kissing cousins, but there are enough pitfalls and minefields in going from one to another that even a Unix guru can stumble, and most guides to Mac OS X are written for Mac aficionados. For a Unix developer, approaching Tiger from the Mac side is a bit like learning Russian by reading the Russian side of a Russian-English dictionary. Fortunately, O’Reilly has been the Unix authority for over 25 years, and in Mac OS X Tiger for Unix Geeks, that depth of understanding shows. This is the book for Mac command-line fans. Completely revised and updated to cover Mac OS X Tiger, this new edition helps you quickly and painlessly get acclimated with Tiger’s familiar-yet foreign-Unix environment.
