Concept
There is very little space available in the entire CCH again this year. To ensure that everyone has space in the building, there will be fewer tables and booths this year and more shared areas, displays and other forms of representation in the habitat.

Group Voucher
Some members of the assembly at 38C3 did enough hours as angels and got an voucher on 2025-10-16 by email. They can buy a ticket and have a guaranteed ticket. When that ticket is paid, a second voucher code is sent to an email address provided during checkout. The second voucher does not guarantee a ticket.
Details about group voucher: to be added
Workshops
We are offering several workshops at 39c3.
OpenStreetMap Software Development – Ask us anything!
OpenStreetMap is not a project but rather a movement with small core and many different applications and libraries to us the data. However, there is no central documentation and finding the right tool for your job is challenging. The first search result might work. Will it point to the right tool on long term? Will you run into performance issues or can it handle the complete dataset? How much memory can do you need for X?
In this Ask Us Anything session, you can ask all the questions about OpenStreetMap data usage as a software developer. As experienced developers for OpenStreetMap based services (and mappers), we have used lots of different libraries and tools to access and modify the data, to calculate routes or render maps.

Day ??, 50 minutes, Meetup, Pretalx
Einführung in den Online-Editor iD
In dieser Session wird euch der Online-Editor iD vorgestellt werden, mit dem ihr zu OpenStreetMap beitragen könnt. Während der Session könnt ihr Fragen zum Beitragen zu OpenStreetMap, dem Mappen, stellen.
Um zu OpenStreetMap beizutragen, ist ein Benutzerkonto erforderlich. Gerne dürft ihr euch vor der Session ein OpenStreetMap-Konto anlegen, dazu benötigt ihr nur einen Benutzernamen und eine gültige E-Mail-Adresse.
This session will be submitted twice.:

Einstieg in JOSM für fortgeschrittene OpenStreetMapper
In dieser Session werde ich den OpenStreetMap-Editor JOSM vorgestellen, eine Java-Applikation für das fortgeschrittene Bearbeiten von OpenStreetMap-Daten. Anders als der Online-Editor iD auf der OpenStreetMap-Website sind auch größere Datenmengen mit JOSM bearbeitbar. Die Anwendung kann mit Plugins, eigenen Tagging-Vorlagen und Kartenstilen an die eigenen Bedürfnisse angepasst werden.
Die Session richtet sich an Interessierte, die schon einmal zu OpenStreetMap beigetragen haben und tiefer einsteigen möchten oder Relationen und größere Objekte (z.B. Landnutzungsflächen) bearbeiten möchten.
Der Workshop richtet sich an Leute, die schon einmal OpenStreetMap-Daten bearbeitet haben.
Um zu OpenStreetMap beizutragen, ist ein Benutzerkonto erforderlich. Bitte legt es vor der Session an. Bitte installiert euch JOSM vor der Session (z.B. aus den Paketquellen eurer Linux-Distribution). Achtet bei der Nutzung der Paketquellen eurer Distribution darauf, dass es sich um Version 18678 oder neuer handelt. Andernfalls könnt ihr damit keine Änderungen hochladen.
