Self-organized Sessions

From 31C3_Public_Wiki
(Redirected from Hacktivities)
Jump to: navigation, search

Usually we called this section "workshops". Then we told you on this page, that a workshop doesn't need to be an event with hands-on and making – but sure it could! We said that a "workshop" is just something, that happens at a special time and place, but doesn't take place in one of the big halls. Therefore we changed the name to "Self-organized Sessions" that includes everything - everything that is organized by you!

Such an event can be...

  • ... a gathering of a project group or on a special topic,
  • ... a contest or a game
  • ... something happening outside of the building
  • ... a small talk or lecture
  • ... a screening of a movie
  • ... something with music, literature and art
  • ... a follow-up-discussion on one ob the "big talks" or another topic that happened rencently
  • ... everything else you think that needs to take place at the congress!

Your Self-organized Session goes 31C3

On this page you can find a list of planned self-organized sessions by participants of the 31C3 and you'll find the necessary information to create your own one.

The idea is, that we will be able to provide a global workshop and talk calendar: Everyone being at the 31C3 is able to look at this calendar and will find out what self-organized sessions are currently running besides the "big" talks in the halls.

Registering own workshops or talks

To register your self-organized sessions just use the self-organized session form.

For now, the crucial information are

  • Name of the self-organized session (which will be used as the site name)
  • A short description
  • A valid email address that might be used by the orga team to contact you

It might even be great, if you give some information about the person and assembly performing the self-organized session and a rough start- and end-time for the schedule, as well as a location. You can always update this information later.

For a detailed description, you can use the Free text field. This field allows the usual mediawiki syntax, and it will be the body of your page at the end.


You can also select a location for your self-organized. There will be again special rooms and places for this, they will be added here soon.

At the moment valid locations are all assemblies that have selected maybe or yes in their local lectures field, as well as the six workshop rooms:

  • Hall 13 with 78 square meters and 41 seats; tables in classroom layout
  • Hall 14 with 60 square meters and 21 seats; tables in U layout
  • Hall 15 with 61 square meters and 25 seats; tables in U layout
  • Hall A with 272 square meters and 230 seats; no tables,
  • Hall B with 287 square meters and 160 seats; tables in classroom layout
  • Hall C with 294 square meters and 120 seats; tables in U layout

Planning self-organized sessions within the workshop rooms works on a "fair use policy":

  • You can plan any timeslot that is still free (FCFS). Take a look into our Calendar or the timelines on the workshop location pages.
  • You may register self-organized sessions in one of the workshop rooms with a maximum duration of 3 hours. If you need more time, you might kindly want to ask one of the Assemblies that provide space for workshops, if you can perform your workshop there.
  • Give a valid contact on your self-organized session page. If no name given, we are not able to contact you in case of questions.
  • Sesseion Annonce Lists available at the Infodesk and on most shared tables

Registered Self-organized Sessions

Already registered self-organized sessions are available as list or calendar. You can use the existing self-organized sessions as a reference, if you do not yet know, where to start.

The calendar is updated using the semantics feature of the self-organized sessions form and template. This may take some time, so be patient...


There are 240 registered self-organized sessions.

"How to survive 31c3" CryptoPartyA network full of hackers can be quite intimidating. We want to address all the questions many of the new visitors might have or regulars might be too afraid to ask by now. And if not all of them then the most urgent ones. The ones that keep your password from being projected onto a wall screen.
'Starbucks franchises personally managed by Joseph Stalin' and other avenirs of the InternetDeparting from the text of Hito Steyerl 'Too Much World: Is the Internet Dead?', the lecture-workshop organised by Avenir Institute (Denis Maksimov & Timo Tuominen) will focus on further analytical and philosophical speculations on subject of potentialities ('avenirs'), that the Internet still might deliver in order to disrupt society, politics and economy. The methodology of avenirologic analysis of futures, which the duo has been developing since issuing in the summer 2015 the book 'Introduction of Avenirology: blueprint into metamodern futures', will be presented as the strategy of futuristic inquiries.

Adopt your MEPAs less and less legislation is coming from national governments and more and more policies are being decided by the EU, we need to take democratic participation to a whole new level. ACTA, net neutrality, surveillance measures - these and many other topics are decided in Brussels. We might not have the same resources as industry lobbyists, but we have the tools! So how should an independent and non-partisan platform look like that could help us enter into a dialogue with our elected representatives? Memopol, PiPhone and Parltrack made a great start, join us for a brainstorming session on how to improve our tools for political engagement. Our goal is that all of us can take away experience on how to contact your MEPs and to share ideas for new tools

Framing Data RetentionData retention was killed decisively by the European Court earlier this year. It's dead - but it's also still moving. It's a ZOMBIE LAW (cue the scary music). We need to design new ways to combat the undead. And we know that new zombie eggs are being hatched as we speak. How to fight those? In our time together we will explore ways to win the fight. By framing the discussion in the most effective way.

Guerillaknitting 101 - Lets Yarnbomb 31C3This session, which is getting a tradition at XC3, will first give a colorful and practical introduction into the art of guerillaknitting, with many inspiring pictures of global knit hacking examples - by individuals, local and global communities with trees, bridges, tanks, cars, planes, stones or power cords covered in knitting. Attendants will learn the basics of how to yarnbomb the 31C3 (or any other place indoor or outdoor). Bring knitting needles and wool but there will also be some material available (if you want to donate yarn, bring it along or bring it to the T-Shirt Shop). Lets join forces to beautify the congress centre! This time, I suggest we use the colour code of the 31C3 for yarnbombing (see long description for details on colours and measures).

Improve booklet on Tails
Improving Anonymity in Bitcoin with CoinShuffleBitcoin's use of pseudonyms (Bitcoin addresses) towards protecting users' privacy has been an attractive feature to many of its adopters. However, due to the inherent public nature of the Bitcoin transaction ledger (the blockchain), Bitcoin does not provide real anonymity in fact. I will present why and how Bitcoin users can be deanonymized. Then I will explain the CoinShuffle protocol, a completely decentralized Bitcoin mixing protocol that allows users to utilize Bitcoin in a truly anonymous manner. The key feature of CoinShuffle is that it is deployable immediately without changing the Bitcoin protocol. Since the protocol introduces only a small computation and communication overhead for its users, it is ready for practical deployment, and several implementations are under way.

MetaHackspaceVernetzungstreffen: Hackspaces werden in ihrer Nachbarschaft und Umgebung immer interessanter. Es entstehen Projekte mit anderen Kulturschaffenden und Bildungsträgern mit und aus den Hackspaces. Leute aus Literatur, Kunst, Bildung und sogar der Politik fangen an Hackerspaces interessant zu finden und sich dort blicken zu lassen. Vereine die sich in der Nähe der Hackspacebewegung befinden wie der Freifunk Rheinland e.V. die sich dank ihrer Organisationsform um eine Mitgliedschaft in der Medienkommission NRW bewerben konnten. Da stellt sich die Frage, inwieweit sich Hackspaces, Makerspaces oder FabLabs gemeinsam insitutionalisieren wollen oder lieber unabhängig bleiben möchten. Dies ist ein Sammeltreffen um im 1. Quartal 2015 ein intensives Brainstorming auf die Beine zu stellen. Interessierte Menschen, kommt vorbei damit wir uns vernetzten können.

Net neutrality - What about interconnect?We want to talk about the problem of inter-connection and possible solutions to the problem. Most net neutrality legislations only cover the end-user side of product creation and maybe some obligations to offer QoS peerings for ISPs.

Is there a way to solve peering-disputes like Comcast/Netflix? Do we have enough data to even formulate political/regulatory/technical solutions to the problem?

In this session we want to lay out the various problems with some real world cases and discuss them with like minded people to maybe find a solution where so far no one else did.

Vorstellung des Freifunk ForumsIm Westen hat sich innerhalb von ein paar Monaten ein gemeinsames Forum etabliert, in dem bereits über 4000 Beiträge geschrieben worden. Mit der Software Discourse haben wir eine Lösung gefunden, die die Kommunikation der vereinzelten Communities stark verbessert hat. Lebhafter Austausch durch einfache Bedienbarkeit und Moderation durch ein Team von Engagierten können der gesamten Freifunk-Community helfen. Zunächst wird die Funktion der Software vorgeführt und die wichtigsten Vorteile gegenüber Mailinglisten dargestellt. Außerdem gibt es einen Einblick in die Erfahrungen, die wir beim Betrieb des Forums gemacht haben. Der Vortrag dient auch als Input zur einer Diskussion, ob das Newsgroups und Mailinglisten langfristig abgelöst werden können.

What's next in the world of designing much needed secure protocols?Brainstorm session about secure `binary reproducibility and verification protocol` protocols. How can we better protect users, leak less metadata and create a more pleasant experience? This workshop will focus on making a design for reproducible builds, what do tools lack for the moment? How can we improve those tools? However, users are not going to compile our software they download the binaries, how can they verify it isn't tampered with? I have a sketch laying in my drawer for months now that I feel should be refined for great benefit of users world wide.
