Last year I properly attended my first Open Source Developers Conference, and this year's - held in Brisbane from November 26 to 29 - is coming up fast.
I'm planning to attend again this year and if you have any developers doing open source work or doing any open source work yourself, I can heartily recommend going. OSDC is a great place to pick up tick and trips and find out how to use your favourite tools and languages in unexpected new ways.
The theme for this year's conference is "Success in Development & Business".
