Sydney Linux Users Group (SLUG)

SLUG's monthly meeting will be held on Friday the 24th of November, featuring talks and SLUGlets. Meetings are open to the general public, and free of charge.

This month's meeting will be at our new venue, the IBM building, Level 13, 601 Pacific Highway, St. Leonards.

We ask that people arrive 15 minutes early so we can all get into the building and start on time.

A committee member will also be standing outside the building to meet, greet, and provide directions to the venue.

Talks

General Talk: John Ferlito - VoIP

John will give a broad overview of VoIP including what codecs people should use, hardware (Phones, ATAs, ISDN and PSTN cards, Mobile Pods), what VoIP providers offer, Asterisk and what it can do.

John will be using Beagle Internet IVR and distributed VoIP Call Centre as a case study.

Technical Talk: Charles Grey - Darbat

Darwin is an open-source subset of Apple's Mac OS X. The Darwin kernel presents a POSIX interface, but is internally an interesting mix of BSD and Mach kernels and the modular device framework, I/O Kit. The kernel boasts modern features such as device hot-plug, power management, 64-bit and soft real-time support.

L4/Darwin (AKA darbat) is a joint project between the Embedded, Real-Time and Operating Systems group at National ICT Australia and the School of Computer Science and Engineering at UNSW. The L4/Darwin project aims to re-factor the monolithic Darwin operating system into a set of components running on top of the L4 microkernel. By running the Darwin kernel as user processes, L4/Darwin aims to provide improved flexibility, robustness and peformance while preserving
binary compatability with native Darwin and Mac OS X.

This talk covers details of Darwin kernel internals and our experiences porting it to the L4 microkernel. It will also cover experiments and results so far, as well as future plans.

SLUGlets Talk: Jon Teh - Asterisk

Following on from John Ferlito's talk, Jon Teh will be diving into Asterisk: what is is and what it can do, including interfacing with various hardware and software communications methods. Telephony in general will be covered briefly to give the audience a suitable context for the demonstration of Asterisk. A primer to the Asterisk dialplan, the heart of any Asterisk system will be given, and asterisk configuration will be demonstrated practically with a live Asterisk server and telephones. Some of the more advanced features will be mentioned, along with possibilities about where people can go from there with their own setups. Participants will be inspired by Asterisk's flexibility and the possibilities it can allow for!
