The Open Source Days conference opened the ticket sale a couple days ago. You can buy tickets for the conference itself as well the many training courses we're arranging in the days before the conference.
See opensourcedays.org for more information and pay attention to the early bird discount that ends about 5 days from now.
Also note that while there's not that many abstracts on the website yet we're going to keep adding batches of new abstracts. There's going to be a lot of interesting talks so keep checking the website for new abstracts and other news.
