39C3 Wrap Up

2026-01-08

The annual Chaos Communication Congreess took place in Hamburg between Christmas and New Year’s. Once again there were many exciting talks and workshops on diverse topics. We learned that the implementation of GPG is insecure, most Bluetooth headphones have major flaws , and of course the German electronic patient records are still broken.

But, there is also good news to report. We now know how to cook for large groups for an event and Marc-Uwe Kling and Linus Neumann called us to participate in the Digital Independecne Day at the end of the live reading from Marc-Uwe Kling. We are also participating! Take a look at our calendar for more DIDay info.

Digital Independence Day

2025-12-27

What is Digital Independence Day?

Digital Independence Day (or in German der Digitale Unabhängigkeits Tag) is a day of action (at least) Germany wide, on which we want to take small steps to become more independent from “Big Tech” companies like Meta (Facebook, WhatsApp or Instagram), Google, Apple, or Amazon.

The idea for Digital Independence Day came from, among others, author and artist Marc-Uwe Kling. He has published a YouTube short presenting the idea (Link to the video).

Statement on the draft law 'Minimum retention of IP addresses'

2025-11-14

A new draft bill by the federal government of Germany proposes a “Minimum requirement for the retention of IP addresses to prevent serious crime”. This draft is problematic for many reasons, as the proposed minimum retention is not feasible with current technological standards and will lead to significant negative impacts on society.

Operating free public Wi-Fi services, such as those provided by Freifunk, is significantly complicated, if not made impossible. Public Wi-Fi services of this kind are an important part of digital inclusion, particularly for people without mobile data contracts, such as socially disadvantaged groups.

Mouse was here!

2025-11-10

Since last year the Open Doors with the Mouse event from WDR has also included soldering workshops, lead by Timo from the Binary Kitchen (who also designed the badge soldering kits), among others.

The Munich Haecksen have already hosted several soldering workshops and have a good rapport with the Binary Kitchen, so they wanted to also participate this year. They registered a “door” under the name “Soldering Workshop” and on the third of October we opened our door to kids that wanted to learn to solder.

Time for Change

2025-09-08

For many years, our hackspace used a page from our wiki as our homepage. Those days are finally over. We have decided to rebuild our website with a static site generator (Hugo).

The xHain website served as the basis for our changeover, but we also drew inspiration from other hackspaces.

With the new look of our website, we not only want to appear more modern, but also make it easier for new interested parties to get started. All important information about our hackspace can easily be found here. The new structure also offers more space to document our projects and events.
