The JAOO conference is coming to Australia again, and I think it will be the best technical conference in Australia this year. (I admit that I'm somewhat biased as a member of the programme committee.) In the lead up to the conference we have organised what we call JAOO Nights in Brisbane, Melbourne, and Sydney. These are free events, starting at 5pm with two speakers presenting on topics that give a flavour of what the JAOO conference itself will be like.
Check out the JAOO Australia site for information on the sessions, and sign up for your city if your interested!
