    - Dave Zarzycki on launchd

    Recently Dave gave a presentation on launchd at Google which they
    recorded as a Google Tech Talk.  Barring any technical difficulties,
    Dave will call in for a live Q & A session at the end of the

    Since time immemorial (or the advent of UNIX--pretty much the same
    thing), the init program ... all has been the first user-space
    program to run on Unix-like systems. As systems grew more complex, so
    did system initialization. The responsibilities of init grew
    multifold and its implementations diverged. Beginning with the
    "Tiger" version of Mac OS X, Apple introduced a powerful new way of
    system initialization: launchd. Launchd isn't just an init
    replacement though--it provides a powerful XML interface for defining
    when, where, and how programs should be invoked on OS X. In this
    talk, Dave, who developed launchd, will discuss the rationale behind
    launchd and how the program came to be. You will also learn about the
    many options launchd provides for defining the interaction between
    the operating system and your code, and how your code can be started
    automatically through launchd.

    Speaker: Dave Zarzycki Dave Zarzycki is responsible for helping teams
    across Apple design and integrate their technologies in the the
    mainline operating system. As a part of this role, he has developed a
    technology called "launchd" to aid those developers.

    - O'Tooles
    We will continue the discussion at our local watering hold Timothy
    O'Toole's at 622 Fairbanks (2 blocks east of the store).

    We also wish to thank the folks who run the theater space at the
    Apple store for letting us have our meetings there, and Jonathan
    'Wolf' Rentzsch for hosting the new and revived CAWUG web site.
    Thanks all.

    Also, if you are working on a project and would like to talk about
    it  briefly / promote it, I think it would be fun for people to hear
    about  other people's projects.  Please email me off line and you can
    talk at  a future meeting or would like a book to review.

    Future meetings dates: 10/9/07 & 11/13/07
