Hey web devs! We knew you'd look under the hood. Please pardon the mess...we still have some clean up to do. If it drives you crazy and you want to help us get it perfect, maybe you should join our team! We could use another set of hands!
Topics covered: How to get around in Darwin, the UNIX implementation built into Mac OS X. Sections deal with basic maneuvering at the command line, LDAP services, C programming, and graphical user interfaces under Aqua. There's a short section on building the kernel itself, but it's limited in scope.
We've come a long way from the early days of the Internet, when many "mailing lists" were simply multiuser aliases maintained by the postmaster of a UNIX server. In those days, it was common for such "list" aliases to have a "-L" suffix, so sys admins and users could easily tell the difference between user accounts and multiuser lists. Subscription was a matter of emailing the sys admin and asking to be added to the alias. All mail sent to the list alias was simply resent, or "exploded," to all the users on the alias.
