The Book of IMAP
IMAP (the Internet Message Access Protocol) allows clients to access their email on a remote server, whether from the office, a remote location, or a cell phone or other device. IMAP is powerful and flexible, but it's also complicated to set up; it's more difficult to implement than POP3 and more error-prone for both client and server. The Book of IMAP offers a detailed introduction to IMAP and POP3, the two protocols that govern all modern mail servers and clients. You'll learn how the protocols work as well as how to install, configure, and maintain the two most popular open source mail systems, Courier and Cyrus. ...

The Art of Debugging
Debugging is crucial to successful software development, but even many experienced programmers find it challenging. Sophisticated debugging tools are available, yet it may be difficult to determine which features are useful in which situations. The Art of Debugging is your guide to making the debugging process more efficient and effective. The Art of Debugging illustrates the use three of the most popular debugging tools on Linux/Unix platforms: GDB, DDD, and Eclipse. The text-command based GDB (the GNU Project Debugger) is included with most distributions. DDD is a popular GUI front end for GDB, while Eclipse provides a complete integrated development environment. ...
