Our goal is to capture the excitement of our conferences, and you may see photographers or videographers (including ones we've hired) documenting this event. Photos or videos taken by or on behalf of O'Reilly may be posted on one or more of our sites or used in future marketing materials and publications. We also encourage attendees to share their conference experiences through social media. It's possible that you would appear in some of these shots. We invite you to speak directly with any photographer if you have concerns about their activities. Please note that audio and video recording or broadcasting of presentations (keynotes, sessions, tutorials, workshops, and training courses) by attendees is not permitted.
