What, exactly, do you know about your body? Do you know how your immune system works? Or what your pancreas does? Or the myriad - and often simple - ways you can improve the way your body functions? This full-color, visually rich guide answers these questions and more. Matthew MacDonald, noted author of "Your Brain: The Missing Manual", takes you on a fascinating tour of your body from the outside in, beginning with your skin and progressing to your vital organs. You'll look at the quirks, curiosities, and shortcomings we've all learned to live with, and pick up just enough biology to understand how your body works. You'll learn: that you shed skin more frequently than snakes do; why the number of fat cells you have rarely changes, no matter how much you diet or exercise - they simply get bigger or smaller; how you can measure and control fat; that your hair is made from the same stuff as horses' hooves; that you use only a small amount of the oxygen you inhale; why blood pressure is a more important health measure than heart rate - with four ways to lower dangerously high blood pressure; why our bodies crave foods that make us fat; how to use heart rate to shape an optimal workout session - one that's neither too easy nor too strenuous; why a tongue with just half a dozen taste buds can identify thousands of flavors; why bacteria in your gut outnumbers cells in your body - and what function they serve; why we age, and why we can't turn back the clock; and, what happens to your body in the minutes after you die. Rather than dumbed-down self-help or dense medical text, "Your Body: The Missing Manual" is entertaining and packed with information you can use. It's a book that may well change your life.

Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new "Linux Security Cookbook" does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes-short, focused pieces of code that administrators can use to improve security and perform common tasks securely. The book includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure. Some of the "recipes" you'll find in this book are: controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more; monitoring your network with tcpdump, dsniff, netstat, and other tools; protecting network connections with Secure Shell (SSH) and stunnel; safeguarding email sessions with Secure Sockets Layer (SSL); encrypting files and email messages with GnuPG; and probing your own security with password crackers, nmap, and handy scripts.

Imagine a set of simple principles that could help you to understand how parts combine to become a whole, and how each part sees the whole from its own perspective. If such principles were any good, it shouldn't matter whether we're talking about humans on a team, birds in a flock, computers in a datacenter, or cogs in a Swiss watch. A theory of cooperation ought to be pretty universal, so we could apply it both to technology and to the workplace. Such principles are the subject of Promise Theory, and the focus of this insightful book. The goal of Promise Theory is to reveal the behavior of a whole from the sum of its parts, taking the point of the parts rather than the whole. In other words, it is a bottom-up constructionist view of the world. Start Thinking in Promises and find out why this discipline works for documenting system behaviors from the bottom-up.

This concise book contains detailed information about Oracle internals -- information that's not readily available to Oracle customers. It lays a foundation for advanced performance tuning of the Oracle database. Based on Oracle8i release 8.1, the book describes many of the secrets of Oracle's internal services: data structures, algorithms, and undocumented Oracle system statistics. Main topics include: Waits - how Oracle processes communicate via semaphores, and how to use the Oracle wait statistics to identify the source of performance problems. Latches - how they keep multiple processes from inspecting protected data structures at the same time, and how to examine and control latch behavior and statistics. Locks - how they work with latches to protect data structures (locks allow multiple sessions to share resources in some cases), and how locks affect performance. There is also a detailed discussion of instance locks, which are used in parallel server environments. Memory - how Oracle uses memory (e.g., the various elements of the System Global Area), and how Oracle dynamically allocates and manages memory. Oracle8i Internal Services is aimed especially at administrators and developers who need detailed internal information to do advanced performance tuning. The book will expand your repertoire of tuning solutions and troubleshooting techniques by explaining how you can use Oracle's hidden parameters and undocumented system statistics to best advantage. NOTE: The author has collected the scripts he has developed for tuning and analysis into a toolkit (known as APT, for Advanced Performance Tuning). These scripts access the Oracle X$ tables directly and provide information not otherwise available. The scripts are available to readers for free from the O'Reilly web site.
