39c3
Winterrail 2025/26
And so it starts! Since yesterday and until January 4th I will be travelling around Europe exclusively by train, carrying with me my lovely foldable bike.
Stops:
Paris (at @mario’s 💕), but also having lovely conversations with @giovannicerboni
Barcelona (for the yearly gathering of the youth movements in @bancaetica Italy and Spain)
Marseille, because going straight back to Italy was a bit too much in one go, so I will just hand out and chill.
Sanremo, to spend Christmas with my family (even though on 21-22 December we will be doing a full-immersion planning with the staff of @scambi)
Hamburg, for #39C3 😍
Berlin, for New Year’s Eve with @dario 💜
Back to Rotterdam to start XPUB’s Special Issue 29 with @doriane yeeeaaaah
I will be (trying to) keep this page and this thread updated with what’s happening.
Federating knowledge: exploring ways to bridge wikis and notes
Join the workshop at #39C3! Day 1, 17:00 @ Free Knowledge Habitat Workshop Area.
Most people and organisations have their very own way of acquiring, organising, 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?
This workshop is going to be heavily centred on a twofold discussion, exploring the challenge of federated knowledge starting from two questions.
What does it mean to federate knowledge repositories?
Instead of pursuing a silver-bullet solution to embrace all use-cases, what would it mean to foster and enable interoperability for different software?
These questions stem from years of questioning and wondering how to integrate my personal note-taking and collective, participatory knowledge management at work, in organisations, institutions, and informal collectives. Recently, I began actively researching this topic as I started playing with the MediaWiki API to cross-synchronise my local Markdown notes and the XPUB wiki, the public learning wiki of the Experimental Publishing master. I am puzzled by taking advantage of the potential of a specific software (in this case, MediaWiki) while fearing of being locked-in.
Some further, more specific, insights and questions:
Local-first approaches and software (e.g. Reflection)
Interesting experiments based on existing protocols, such as Ibis
What do we take of semi-open and obscure yet very cool initiatives like Anytype
The power and the limits of plain-text: how to enable collaboration on simple Markdown files and build on top of it, as @Obsidian does

Good Morning 2026!
Here are some sounds you might enjoy for a chilled and happy new year:

Part 1 of the 3-hour set. Recorded at the toilet, Halle H - #39c3 - Chaos Communication Congress (Hamburg)
Toilet raves at the congress… it was ZAUBERHAFT
What was planned as a 1-hour gig suddenly became 3 hours. TIMETRAVEL - only possible here :-)
Big up to all who joined! —> #Leftathlon Crew! 🚀

Sound quality is a bit sh**ty.. but hei, who cares. It was so much FUN!
Chill-Out Set coming tomorrow..
Fände es s. nützlich, wenn sich berufenere Leute als ich zu diesem Text äußern könnten, gerne auch im weiteren Rahmen des #39c3
Der Autor schreibt zu KI-Slop "Hier geht es nicht mehr um das traditionelle Handwerk, [...], sondern primär um die eigentliche Idee, die man zum Ausdruck bringen will." und tituliert das "Demokratisierung des Schaffensprozesses".
Ich krieg die Tür nicht mehr zu, und bin SO dicht davor, meinen Job ersatzlos hinzuschmeißen, tbh.
In case anyone wants to find me at #39C3, I am mostly hanging around the Hakkavélin assembly. But also roaming a lot.
