- 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 presentation.

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
