Free Software Foundation Europe

The Free Software Foundation Europe is a charity that empowers users to control technology.

Software is deeply involved in all aspects of our lives, and it is important that this technology empowers rather than restricts us. Free Software gives everybody the rights to use, understand, adapt, and share software. These rights help support other fundamental freedoms like freedom of speech, press, and privacy.

Freie Software Freunde e. V.

FSuB e.V. Freie Software und Bildung

We are promoting the understanding and self-determined use of information technologies based on Open Standards and Free Software.
We want to present projects from our work.
We are working on an update for the moinmoin wiki. That's why we would be happy to hear from developers who want to contribute to moinmoin 2.0.

Gentoo Linux

Gentoo Linux is a meta-distribution that gives the user as much freedom as possible, but also as much help as necessary. An easy-to-use package management system (Portage) compiles almost all programs from source code, which offers alignment with the wishes and needs of the user to the greatest extent. The Gentoo Linux distribution primarily targets more experienced users. However, if you are willing to read something and deal with the subject a little, you will also reach the goal as a beginner. Here you can learn Linux from scratch.

HSAdmin NG (Genossenschaftliches Cloudmanagement)

HSAdmin NG is the successor of HSAdmin, an administration tool for the cooperative management of a community cloud. The distributed system is a multi-level multi-tenant open source management tool for cloud environments.

The focus is on the management of members and contact persons as well as their access rights to objects of the cloud environment. The core, based on Spring Boot and PostgreSQL, checks access rights and delegations of access rights before changes to the target state are transferred to the database in an audit-proof manner and a connected configuration management system such as Saltstack is tasked with changes to the managed IT systems (actual state).

The tool set is particularly suitable for organisations that want to offer cloud services to their members on an open source basis.

The contextual, role-based access control module has been implemented directly in the PostgreSQL database system, so that filtering happens on views of entities in the database, which ensures the security and scalability of the overall system. The security model has a Java-based test coverage.
For the functional modules, this is done transparently with updatable views. Benchmarks prove the highly scalable performance of the system.

A first specialised module for the administration of cooperative members and their shares as well as debtors and contact persons has already been developed. External applications can be quickly and efficiently programmed against HSAdmin's API in any programming language.

The project is in an early stage of development. The core component of HSAdmin NG, the Role Based Access Control module and the module for cooperative administration HS Office are already available. The roadmap now foresees the development of IaaS and PaaS modules as well as a web front-end.

We will present the software, explain the current roadmap and support interested visitors in setting up the development environment.
We also look forward to exchanging ideas with the community and are happy to receive ideas and feature requests.



Matrix is an open network for secure, decentralised real-time communication.

Matrix is decentralised. This means there is no single authority, which owns your communication. Matrix gives the control over communication back to users.

Matrix is federated. This means you can run your own (open sourced) Matrix server (called home-server) and still communicate to the whole network. You can decide which rooms to share with the network and which to leave private to your home-server.

With ton of bridges Matrix can connect to other (proprietary and open) networks and bridge them into Matrix. This way you can have all your conversations in one place and on all of your devices.

Thanks to End-to-End-Encryption (short E2EE) Matrix secures your data so that even the home-server cannot decrypt it.

Encrypted voice and video calls using WebRTC are also supported.

Integration and widgets is also a unique feature for Matrix, which allows you to embed web content directly in the Matrix room.

We have a big and friendly community, join us at ( !

Neuropil Cyber Security Mesh

Neuropil is a small c-library which by default adds two layers of encryption to communication channels. The Cyber Security Mesh enables global addressing of identities (a device, an application, a service or a person) without compromise for privacy or security requirements. The project embraces modern concepts like named-data networks, self-sovereign identities, zero trust architectures and attributes based access control to increase the cybersecurity level of it’s users beyond the current state-of-technology.

Ubuntu + Ubuntu Touch

The Ubuntu project settled its way so that Linux can be more accessible to a bigger mass. And it should never mind how much knowledge or handicaps are available. Everybody should be able to use the computer as support for different tasks or spending his free time.

The Ubuntu project is not only concerned with keeping the operation of a computer as simple as possible, but also with making access to the community and participation in the project possible for everyone in the simplest way possible.

To make it easier to get started, Ubuntu comes with the most important applications (office applications, browser, e-mail programme, ...). The motto is: only one application for one purpose, so as not to confuse beginners unnecessarily.

Ubuntu is released every 6 months to make new developments and improvements available to the user in a stable environment. Those who prefer to stay with one version for longer can also use a long-term version.

Ubuntu is not only available on the PC, server or laptop, but also on the smartphone, tablet, Raspi, etc. With Ubuntu Touch, a free alternative operating system has been made possible on smartphones.
