Debugging is the art of finding mistakes in code by tracing program execution line by line. This book will help programmers master the art of debugging with two popular Open Source debuggers: GDB and DDD. The book integrates general debugging principles with concrete examples and covers many topics other debugging books leave out, such as segmentation faults, threaded programming, and distributed/parallel programming.

If you've asked someone the secret to writing efficient, well-written software, the answer that you've probably gotten is "learn assembly language programming." By learning assembly language programming, you learn how the machine really operates and that knowledge will help you write better high-level language code. A dirty little secret assembly language programmers rarely admit to, however, is that what you really need to learn is machine organization, not assembly language programming. Write Great Code Vol I, the first in a series from assembly language expert Randall Hyde, dives right into machine organization without the extra overhead of learning assembly language programming at the same time. And since Write Great Code Vol I concentrates on the machine organization, not assembly language, the reader will learn in greater depth those subjects that are language-independent and of concern to a high level language programmer. Write Great Code Vol I will help programmers make wiser choices with respect to programming statements and data types when writing software, no matter which language they use.

The second volume in the Write Great Code series supplies the critical information that today's computer science students don't often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language.

OpenPGP is the most widely used email encryption standard in the world. It is based on PGP (Pretty Good Privacy) as originally developed by Phil Zimmermann. The OpenPGP protocol defines standard formats for encrypted messages, signatures, and certificates for exchanging public keys.
PGP &amp; GPG is an easy-to read, informal tutorial for implementing electronic privacy on the cheap using the standard tools of the email privacy field - commercial PGP and non-commercial GnuPG (GPG). The book shows how to integrate these OpenPGP implementations into the most common email clients and how to use PGP and GPG in daily email correspondence to both send and receive encrypted email.
The PGP &amp; GPG book is written for the moderately skilled computer user who is unfamiliar with public key cryptography but who is nevertheless interested in guarding their email privacy. Lucas's trademark informal and relaxed tone makes public key cryptography as simple and clear as possible, so that any reasonably savvy computer user can understand it.

FreeBSD—the powerful, flexible, and free Unix-like operating system—is the preferred server for many enterprises. But it can be even trickier to use than either Unix or Linux, and harder still to master.
 Absolute FreeBSD, 2nd Edition is your complete guide to FreeBSD, written by FreeBSD committer Michael W. Lucas. Lucas considers this completely revised and rewritten second edition of his landmark work to be his best work ever; a true product of his love for FreeBSD and the support of the FreeBSD community. Absolute FreeBSD, 2nd Edition covers installation, networking, security, network services, system performance, kernel tweaking, filesystems, SMP, upgrading, crash debugging, and much more, including coverage of how to:
<ul>
<li>Use advanced security features like packet filtering, virtual machines, and host-based intrusion detection</li>
<li>Build custom live FreeBSD CDs and bootable flash</li>
<li>Manage network services and filesystems</li>
<li>Use DNS and set up email, IMAP, web, and FTP services for both servers and clients</li>
<li>Monitor your system with performance-testing and troubleshooting tools</li>
<li>Run diskless systems</li>
<li>Manage schedulers, remap shared libraries, and optimize your system for your hardware and your workload</li>
<li>Build custom network appliances with embedded FreeBSD</li>
<li>Implement redundant disks, even without special hardware</li>
<li>Integrate FreeBSD-specific SNMP into your network management system.</li>
</ul>
Whether you're just getting started with FreeBSD or you've been using it for years, you'll find this book to be the definitive guide to FreeBSD that you've been waiting for.

Cisco routers and switches are the cornerstones of many networks. But when things break, repairs can intimidate even the most competent administrator. Luckily, just knowing the "in case of emergency" basics will take you far.
 Just like the original, this second edition of the highly acclaimed Cisco Routers for the Desperate is written for the administrator in crisis mode. Updated to cover switches and the latest Cisco terminology, with a tighter focus on the needs of the small network administrator, this second edition gives you what you need to know to provide reliable network services and fix problems fast. You'll find coverage of:
 <ul>
<li>Installation—how to get your router and network connections up and running right the first time</li>
<li>Troubleshooting routers and switches, so that you can determine whether your hardware or the Internet is broken</li>
<li>Security concerns, like how to keep your network equipment safe from hackers and install a private network between two offices</li>
<li>How to implement basic network redundancy to reduce the risk of network downtime</li>
</ul>
 Cisco Routers for the Desperate, 2nd Edition is designed to be read once and left alone until something breaks. When it does, you'll have everything you need to know in one easy-to-follow guidebook.

From the earliest phone phreakers to today's most pernicious phishers, Steal This Computer Book Reloaded explores the world of hackers, crackers, virus writers, scammers, and other members of the Internet underground. Essential reading for anyone connected to the Internet, this offbeat, non-technical book examines what hackers do, how they do it, and how you can protect yourself. Written in the same informative, irreverent, and entertaining style that made the first four editions hugely successful, Steal This Computer Book Reloaded will expand minds and raise eyebrows. The entire book has been rewritten, and key sections have been revised to expose the latest dangers lurking online and off as well as the increased political ramifications of hacking by both corporations and national governments. New chapters discuss cyberwarfare, recently discovered security vulnerabilities and hacker tools, remote attacks, and digital spying programs.
