Space is limited, unfortunately.


  • You will need a wristband to gain access to the tutorials.
  • Wristbands will be available at the registration desk.
  • You can pick up wristbands for tutorials for the same day only.
  • Wristband wearers need to enter the tutorial room up to five minutes before the tutorial starts. At that time, any remaining seats are available to anyone.


At our conference in 2019, more people wanted to attend the tutorials than we had seats to offer, and the rooms were overcrowded. This year, like in past years, we will distribute tutorial seats fairly across all attendees interested in attending tutorials without queuing at the rooms, or overcrowding.

Seat Distribution

To access a specific tutorial, a wristband for that tutorial is required. For example if you want to attend the refactoring tutorial, you need to present a wristband for the refactoring tutorial. Wristbands are only valid for one particular tutorial.

How to Get the Wristbands / Reserve a Seat for a Tutorial

Please come by the registration to pick up the required wristbands.

Wristbands are available for tutorials for the same day only.

Attending Tutorials

Tutorials are expected to become crowded. Therefore, we would like to ask everyone:

  • Please be at the tutorial room 10-15 minutes before the tutorial starts
  • Please seat in a fashion others can join in easily avoiding empty seats in between
  • Please keep in mind everyone must be seated on a chair. According to the Veranstaltungsordnung neither we nor the venue may allow standing or sitting on the floor.
  • There are power outlets available in each tutorial room, please be mindful and share the charging capacity with others in the room.
  • Once the tutorial is finished everyone must leave the room, even if you have a wristband for the consecutive tutorial. Please leave the room in an orderly and effective fashion. If you’d like to keep chatting with the instructor(s) or with other attendees, please move the conversation to the area outside the tutorial rooms. This way the next instructor(s) can start preparing, and our volunteers can easily bring in the attendees for the next tutorial.

Please keep in mind:
Seats not taken five minutes before the tutorial will be considered available to anyone. If you arrive with a tutorial wristband five minutes or less before the tutorial and can’t get a seat, then you cannot participate. We ask you to leave the room quietly and let the attendees respect those that arrived on time and followed these guidelines. Maybe try another tutorial?

Wristbands are not personalized

If you want to change which tutorial you go to, feel free to exchange and trade tutorial wristbands with other attendees at the conference. You can also return to the stations for exchanges, pending availability.
