Zielgruppe für diesen Workshop sind be_hinderte Congress-Besucher:innen (CCCrips). Eine Hackspace- oder C3-Mitgliedschaft ist komplett optional. Wir wollen uns untereinander kennenlernen, Erfahrungen austauschen, und Pläne schmieden! Weltherrschaft, anyone?

Ich möchte mit euch das Netzwerk erkunden, vom Endgerät bis zum Router, der das Internet "anruft". Wir werden uns auf das lokale Netzwerk beschränken und zum Schluss einmal durch spielen was im Netzwerk auf der Leitung eigentlich passiert.

We will give a brief introduction to the Reticulum Network Stack and announce what is new in 2025: - Reticulum will soon be available in Rust, which will allow users of embedded systems a better performance. - The new Reticulum BLE Interface enables the creation of autonomous mesh networks without any further hardware or central server. The interface can be used on Linux and Android. - The Columba App for Reticulum lowers the barrier of entry for using Reticulum.

What would it look like to build financial infrastructure for solidarity rather than speculation? While blockchain technology has largely been captured by libertarian and extractive market logic, it certainly does not need to be that way. In this talk, we'll explore Solidarity Primitives, development and architectural design patterns designed to forge economic solidarity between individuals and collectives. Drawing from our work at Bread Cooperative and research I've documented through my podcast, The Blockchain Socialist, we'll examine concrete examples like the BREAD community token, savings circles implementation, and the Solidarity Fund mechanisms that enable participatory funding without relying on venture capital or traditional financial intermediaries. We'll discuss how these primitives address a critical gap: the technical and coordination barriers that have historically made alternative economic models difficult to implement at scale. From worker cooperatives to mutual aid networks, the infrastructure simply hasn't existed. Peer-to-peer technologies can change that but only if designed with solidarity, not profit maximization, as the core principle. This talk is for anyone interested in the practical dimensions of building a post-capitalist economy: what does it actually look like to write code for collective autonomy? How do we ensure decentralized systems serve communities rather than concentrating power?

Online anonymity is being demonized and undermined. But anonymity has an important social function for preserving individuals and group against social threats. We will argue for the philosophical and political value of being anonymous, especially against the rising state of capture in state and corporate surveillance. Anonymity is more than namelessness: it's a tool of resistance.

Auf dem Bundesparteitag der Grünen habe ich den Antrag gestellt, sich für ein europäisches Grundrecht auf Verschlüsselung einzusetzen. Dieser Antrag wurde angenommen und ich will jetzt mal schauen, inwiefern dieses Thema außerhalb der Politik auf Unterstützung trifft und wie man zum Beispiel in der Zivilgesellschaft dafür Verbündete finden kann.

Chaos prepping in case of communication collapse Was würden wir tun, wenn dies der letzte Congress wäre, wo wir in der gewohnten Art miteinander kommunizieren oder uns frei miteinander treffen könnten - wenn ein nächster Congress wegen Faschisten, Überwachung und/oder anderer Katastrophe in dieser Form nicht mehr möglich wäre? What would we do, if this would be the last congress in which we could meet freely and communicate in the known way, if a next congress somehow would not be possible this way, because of faschism, surveillance and/or other catastrophe? Ein kurzer Austausch zu Szenarien und Ansätzen, damit umzugehen. A brief exchange on scenarios and possible ways to deal with them.

Computer programs run with all privileges of the running user. If your user can read your emails, then so can any other program you run. However, many programs do not need most permissions and perhaps should not have them at all. This workshop demonstrates quite simple ways in which software can self-restrict itself. The focus will not be on foreign, potentially malicious software, but on hardening programs against misconduct and future security vulnerabilities. Several operating systems have developed different interfaces that restrict software beyond its normal scope. This workshop will focus on POSIX and especially OpenBSD because of its user-friendly APIs. Although other operating systems, such as Linux, will be discussed, they will not be covered in depth due to their more complicated APIs. Within the workshop part, software with known security vulnerabilities is then patched together - usually with almost a single line. Ideally, an exploit has hardly any effect afterwards, although the vulnerability is still present. This is not intended to encourage carelessness, but rather to demonstrate the development of a further safety net for software. A basic understanding of programming is required and, more importantly, an interest in the topic. You will need to bring an SSH client, for example a laptop with (almost) any operating system. The language will be either English or German, depending on who shows up.

Can organisations with limited resources be digitally sovereign and still provide modern services? It is not trivial, but the FSFE proves it's possible. In this workshop we want to share our story and hear from you how you are running your NGO on FreeSoftware.

Wir begeben uns auf eine Entdeckungsreise durch Linux - von der Vielfalt eines Betriebssystems. Was ist (F)OSS? Wie sieht so ein Linux aus? Was kann man damit machen? Und kann man damit auch spielen?

Jeden Tag geben wir einen kurzen Einblick in den Aufbau der CADUS Academy: unserer offenen Lernplattform für medizinische, technische und psychosoziale Trainings. Wir zeigen, wo wir gerade stehen, welche Ideen wir verfolgen und wie die Community sich einbringen kann. Fragen, Feedback und spontaner Austausch ausdrücklich willkommen.
Ein Crashkurs, in dem wir praktisch ausprobieren, wie man am Besten eine Person trägt, die nicht mehr selbst mobil ist. Ob verletzt, bewusstlos oder einfach nur betrunken - es schadet nie zu wissen, wie man in brenzligen Situationen nicht nur Verantwortung, sondern auch einen Körper trägt.

You are a FSFE volunteer or you would like to know more about the Free Software Foundation Europe? Then this is the place to be. We will be discussing current activities, future activities, and what will be happening next. You are welcome to join us for some food and drinks while sharing your ideas and learning all about the FSFE and its current activities.

In this presentation, we’ll take a quick look at lots of different applications that use Wikidata data.

Most people and organizations have their very own way of acquiring, organizing, archiving, sharing, and collaborating on knowledge repositories. A broad spectrum of opinions and approaches resulted in a diverse and rich ecosystem of knowledge management solutions. Nevertheless, this also implies scattered and disconnected knowledge sources. What would it mean to build bridges among wikis and federate knowledge?

WhatsApp groups have become the default tool for coordinating anything. Also, WhatsApp groups are terrible. We all have stories. From an architectural point of view, they are terrible because the least configurable platform. There is a 1 and a 0 - you are a member of a group and get every message, or you are not a member and get no message. We used to have tools that worked better. Every forum built on free forum software would work better. The problem is - everyone who hears "we should organise" immediately imagines a WhatsApp group. There is knowledge out there about how to build tools and help people organise through them - but we have no language. I am proposing Collaboration Architecture. What do we think?

Wir sind vom Nebelhorn Podcast der Scientists for Future in Hamburg und führen in unregelmäßigen Abständen Interviews, meist zu Klima und Gesellschaft. Je nach Gelegenheit werden wir auf dem 39c3 ein kleines Interview oder eine Hinter-den-Kulissen Sonderfolge aufnehmen. https://nebelhorn.podigee.io/

Mit dem Format **live** ist der Podcast auch regelmäßig auf Kongressen zu finden und diskutiert interessante Vorträge mit ausgewählten Gästen.
