Apart from that, here's a good grocery list of topics just to give you ideas. We're interested in everything including software development, software product development, UX, startups mobile, web, devops, data processing, scaling and more. You should know - this is not a closed list, if your topic doesn't seem to fit here and is of general interest, we want it!
Unlike last year, we do not set out a closed list of tracks. This time we'd like to leave the topics (tracks) open and only after accepting the submissions we might devide up to tracks, but we will not rule out a single good talk just b/c it's not a natural fit to any predefined list, so don't worry so much about categorizing your submissions.
