COSCUP 2025

Simon Hornbachner

Simon has worked both professionally and as a volunteer in various areas of free and open-source software, as well as security. After completing his Bachelor's degree in security, he began his professional career as what would now be called a "SecDevOps" engineer, developing infrastructure automation code and deploying and operating automated patch and vulnerability management systems. Following that, he transitioned into a product manager role in the Austrian public health insurance sector, where he was involved in setting up and running the FOSS strategy board, clearance processes, and community engagement programs.

In the last couple of years, Simon has worked as a security consultant and subsequently started his own business to focus on the intersection of software user rights, security, and IT strategy. His aim is to help both for-profit and non-profit organizations succeed in creating sustainable and resilient organizational and technical systems that support their organizational goals, empower their users, and are secure.

For leisure, Simon is an avid board gamer and tabletop RPG game master.

OpenDesk - A European Open Source Online Collaboration Suite
Simon Hornbachner

OpenDesk is an online office and collaboration suite based on open source software, primarily intended to enable public administration to run a sovereign in-house collaboration stack. Covering most common corporate use cases such as online fileshare, collaborative document editing, text chat and online meetings, it is built on mature and proven open source products such as Nextcloud, Matrix and OpenXchange, tightly integrated to work seamlessly as a single software stack.

Stewarded by the German Center for Digital Sovereignty in Public Administration ("Zentrum für Digitale Souveränität der Öffentlichen Verwaltung" - ZenDiS), it is a true Public Money - Public Code project.

This talk will give a short introduction into the project itself, and show in a live demo how OpenDesk improves on existing open source projects by focusing on one aspect that is a common blocker for corporate adoption: tight integration and a consistent user experience.

"Open Gaming" - Content Licenses in TTRPGs for Fun and Prof… nevermind
Simon Hornbachner

Table-Top Roleplaying Games, especially Dungeons & Dragons, have seen a renewed popular interest in the last few years after being prominently featured in shows such as Stranger Things or The Big Bang Theory.
To an extent, open licensing has been a part of this culture ever since Wizards of the Coast (WotC) - the company behind the popular TTRPG Dungeons & Dragons - has published their first version of the "System Reference Document" under the "Open Gaming License." With the most recent update of the D&D rules, this has gained more attention after WotC tried to change and revoke previous versions of the OGL in late 2022/early 2023, finally resulting in community pushback and a new SRD under a Creative Commons license.

This talk will take a light-hearted look into license topics around TTRPG games, what questions and challenges there might be, and what other TTRPG systems out there have or claim to have "open" licenses.
