Open Event Ticketing and Management System

    Juan Pardo ( OpnTec)

The Open Event Server enables organizers to manage events from concerts to conferences and meet-ups. It offers features for events with several tracks and venues. Event managers can create invitation forms for speakers and build schedules in a drag and drop interface. The event information is stored in a database. The system provides API endpoints to fetch the data, and to modify and update it. Organizers can import and export event data in a standard compressed file format that includes the event data in JSON and binary media files like images and audio. The Open Event Server exposes a well documented JSON:API Spec Compliant REST API that can be used by external services (like the Open Event App generators and the frontend) to access & manipulate the data.

Memex - a distributed search engine for your digital knowledge

    Oliver Sauter (

Can we do better than bookmarks? Pretty sure. A talk about new ways of *thinking* about knowledge management and a future of collaborative web-research.

From rules to AI algorithms

    Michael Christen ( SUSI.AI)

Artificial Intelligence in intelligent digital personal assistants are not simple chatbots. They are driven by the deduction rules of expert systems and the principle of machine learning. In this talk we learn how this technology is used in detail using the SUSI personal assistant framework. Rules - in the context of the conversational web now called ‚skills‘ - are implemented with the combination of a backtracking system combined with cloud access to external knowledge. We will learn how a expert system-based personal assistant works and why it can be very easy to write skills for such a system.

Status of the Open Source GPU Support

    Robert Foss

Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have Open Source support and for those that aren't supported yet, improvements are happening at a rapid pace.In just the last year Vivante GPUs have gained mainline support and Mali GPUs have seen good progress being made. In addition to that one of the largest drivers ever merged was submitted by AMD.In this talk, Robert will cover the current Open Source GPU support for Linux, give an overview about their current status, what lies ahead and how the Open Source state of the art compares to the proprietary alternatives.

End-to-end Encryption in Nextcloud

    Jos Poortvliet ( Nextcloud)

Nextcloud introduced End-to-end Encryption in Nextcloud 13. This offers the ultimate protection for your data, securely encrypting it on your devices before it is sent to the server. While this means some feature loss (no online editing! No public sharing!), when used for a sup-set of extremely sensitive data like your credit card details, drivers license or the fiscal year report draft of a company, it is a unique and crucial addition to a file sync and share solution.

The Nextcloud End-to-end Encryption design is unique in several ways, offering a fully secure way of sharing without passwords, easy addition of new devices and an optional admin recovery key.

In this presentation I'll go over the requirements we defined, the threat model we applied and the full design of the solution. No code or algorithms, but high level "what does what, when and how". I promise pretty diagrams to help you understand a complex solution to a complex problem!
