      11:21 - 11:26
      Enough: an app and a community to help journalists, sources and HRD

        Loïc Dachary (Artisan Logiciel Libre Enough Community)

      Investigative journalists should maintain a secure communication channel for exchanging information and documents with their sources. When a whistleblower sends a document, it often ends up in DropBox, Google Drive or iCloud. Although they have good security measure, and can be trusted to fight against malicious people, they can also be expected to do everything in their power to keep being the third party everyone needs. Journalists and human rights defenders need to free themselves of dependencies on third parties: it is an effective way to increase the security of their communication and protect the privacy of their data. Enough is both a NextCloud app and a community committed to help them change. Once they start to use NextCloud as an alternative to DropBox and other similar services, it opens a path where they can learn about new security concepts.
      11:26 - 11:31
      Undoing a Ransomware infection

        Nextcloud Georeplication

          Stefan Heitmüller

        We are going to setup a demo with S3 storage-backed Nextcloud instance where the S3 Minio storage will be replicated automatically to another geographic location. Also, we add MySQL Master/Slave replication for the database to be able to switch over to the backup instance in a worst-case scenario like fire.

        I'll also discuss alternate approaches plus pros and cons of different solutions.

        The lab demo runs with Docker.

        17:00 - 18:50
        Federated data storage and communication

          Marcel Waldvogel (Professor University of Konstanz), Klaus Herberth ( University of Konstanz)

        The Cloud is that powerful magic world, where everything is possible. Behind the shiny marketing, however, the Cloud is only someone else's computers. Those owners often have their own goals, which rarely align with your goals as the user.

        Regaining control over your data and communication is easy. Massive, centralized solutions have many problems; but isolated islands for data and communication are rarely attractive. One of the greatest features of Nextcloud is Federated Cloud Sharing, automatically building bridges on demand between these islands, combining autonomy and independence with utmost flexibility.

        Federated solutions (scalable, yet flexible) not only work for data sharing, nation states, and the Galactic Federation. it also works for communication. XMPP is powerful and secure federated Instant Messaging protocol, to match all the social and/or privacy needs.

        In the course of this workshop, we will guide you to set up Nextcloud and extend it with XMPP. We will bring Raspberry Pis, but you can also bring your own device.

        Please do bring a laptop with web browser and SSH client to configure the Raspis.


        Die Cloud ist das Zauberwelt, die alles möglich macht. Dass aber dahinter nur die Computer Anderer stehen und diese ihre eigenen Ziele verfolgen, wird meist übersehen. Dabei ist es so einfach, selbst die Kontrolle über die Daten und die Kommunikation zu erlangen. Insellösungen reichen meist nicht, da wir dann doch soziale, vernetzte Menschen sind, die einige ihrer Daten auch teilen wollen.

        Föderierte Lösungen sind da der richtige Ansatz: Skalierbar und trotzdem flexibel,ist die Föderation bekannt als Struktur vieler europäischer Staaten und der Galaktischen Föderation. "Föderiert" bedeutet bei Datenspeicherung Nextcloud, bei Kommunikation XMPP, auch als Jabber bekannt. Im Rahmen dieses Workshops können die Teilnehmer unter Anleitung eigene Datenspeicher auf einem Raspberry Pi unter Nextcloud einrichten und vernetzen sowie mit föderiertem Instant Messaging erweitern.

        Mitbringen soll jeder Teilnehmer einen eigenen Laptop mit Webbrowser und SSH-Client.

        Scalability of the PPP app used for free NC instances

          Dennis Pennings (CEO/CTO 360ICT)

        We make it possible for people to easily make use of free Nextcloud instances. The free instances relies on the PPP app, which isn't very scalable and only usable in single instance. This workshop is ment for the PP's to brainstorm on what design is more suitable for more scalability and to be able to use more than one instance with the PPP app. One suggestion is to use the Global Scale siteselector to create a directory service in front of multiple instances:

        Nextcloud as a single-logon hub

          Marcel Waldvogel (Professor University of Konstanz)

        Integration between two services is always a challenge, especially if end users are involved. We tell you how JSXC mastered this challenge of seamlessly integrating a client-side chat app into Nextcloud, while at the same time authentication to a back-end federated XMPP server.

        Many small and medium organisations administer their users in Nextcloud, as no additional tools or setup is required. We show how the same tool we created for JSXC integration can allow you to get rid of separate account management for other services, most notably email. User administration has never been so easy!

        12:03 - 12:08
