Programmers can now do distributed computing with Macs over TCP/IP networks, including controlling remote applications with AppleScript and calling AppleScript methods on code libraries that are located on other machines. It also covers using the Sherlock find application to automate web and network searching and insights on scripting new Apple technologies such as Apple Data Detectors, Folder Actions, Keychain Access, and Apple Verifier.

FreeBSD is by far the most popular version of BSD(r), the legendary operating system that has contributed a great deal to every version of Unix(r) in use today (including Mac OS(r) X). Originally a community effort by the University of California at Berkeley, FreeBSD was aimed at making Unix a little friendlier and easier to use. By the time other free operating systems came along, BSD was firmly established and very reliable. And it continues to be today. For seven years, the FreeBSD community has relied on Greg Lehey's classic, The Complete FreeBSD, to guide them through its configuration and administration. The 4th edition, covering version 5 of FreeBSD, is now available through O'Reilly Community Press. The Complete FreeBSD is an eminently practical guidebook that explains not only how to get a computer up and running with the FreeBSD operating system, but also how to turn it into a highly functional and secure server that can host large numbers of users and disks, support remote access, and provide web service, mail service, and other key parts of the Internet infrastructure.The book provides in-depth information on installation and updates, back-ups, printers, RAID, various Internet services, firewalls, the graphical X Window system, and much more. Author Greg Lehey is a member of the FreeBSD core team and has been developing, documenting, and advocating for FreeBSD for nearly ten years. Whether you're an experienced Unix user or just interested in learning more about this free operating system and how you can put it to work for you, this do-it-yourself BSD documentation will provide the information you need. The Complete FreeBSD is the second release in the O'Reilly Community Press Series. Unlike classic O'Reilly animal books, which are created to fill an information void, the Community Press titles provide convenient printed copies of documentation that is already available online. O'Reilly's role in the series is limited to providing manufacturing and distribution services rather than editorial development, so that each Community Press title reflects the editorial voice and organization of the community that has created it.

The most complete, authoritative technical guide to the FreeBSD kernel’s internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition’s content is completely new, and another one-third has been extensively rewritten.

Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel’s current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down–from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking.
