The cost is $230 and the early bird date expires on the 15th of October.
OSDC is a grassroots-style conference designed by developers for developers, covering open source languages, tools, libraries, operating systems, licences and business models. The conference will include tracks devoted to Perl, Python, PHP and other tools.
You can register online at http://www.osdc.com.au/
The conference has 60 talks in three streams over 3 days. There will always be a talk on that will interest you, there will probably be two or three talks on at the same time which interest you and you'll have to pick between them. It's going to be great fun.
We look forward to seeing you in December!
All the very best,
OSDC Program Chair
