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!

Data Mining for Good Using random sampling, entity resolution, communications metadata, and statistical modeling to assist prosecutions for disappearance and genocide in Guatemala

For over thirty years, human rights groups in Guatemala have carefully documented the killing and disappearance of many people in the early 1980s. There are tens of thousands of records in many databases, and over 80 million paper pages of police records available in the Archives of the National Police. Most of the prosecutions of the former military and police officials who committed the atrocities depends on eyewitnesses, specific documents, and forensic anthropologists' examination of exhumed bones. However, data analysis helps to see the big patterns in the violence.

This talk will explain how data analysis illuminated the selective patterns among mass killings in the prosecution for genocide of former de facto President General José Efraín Ríos Montt. The talk will also explain how looking at the communications metadata from over 20,000 randomly sampled paper memos helped illuminate command patterns in a disappearance case

Proper release practices Best practices for responsible release process of circumvention tech tools Mieke van Heeswijk will explain how Publeaks got started, what it is about and what the plans are for the future.

The Publeaks Foundation and a large number of Dutch media outlets are today launching , a website for people to leak documents to the media securely and anonymously. The initiative is designed to protect whistleblowers, shed light on wrongdoings and encourage and support investigative journalism.

Publeaks is a secure channel. It facilitates safe leaking to the press: the sender remains completely anonymous and he or she can choose which of the participating media outlets receive documents, sound fragments or photographic material. Recipient media outlets can process these files in a protected environment.

Publeaks is based on the GlobaLeaks software package developed by the Hermes Center for Transparency and Digital Human Rights. The Publeaks organization has no access to the leaked files, does not publish anything itself and has no means of identifying the informant. Participating media outlets have committed themselves to verifying the leaked materials, finding sources to support the content and hearing all sides before publishing anything. Journalists can put questions to the anonymous informant on a secure part of the site.. The informant decides whether or not to answer them. Journalists who receive material through Publeaks will know which other media outlets have received the same material and can decide whether or not to undertake a collaborative investigation.

Publeaks is an initiative of the Publeaks Foundation. The foundation takes measures to support press scrutiny and is financed by the participating news media: AD, ANP, De Correspondent, De Groene Amsterdammer, De Volkskrant, Het Financieele Dagblad, het Parool, NOS, NRC Handelsblad, Nieuwsuur,, Pownews, RTL-Nieuws, Trouw and Vrij Nederland. This collaboration of almost all leading Dutch news organisations is a unique initiative without global precedent, in a time that safety, privacy and protection of whistleblowers is more relevant than ever.

So, what is nonetheless working, what is supporting the creation? Is prototyping producing matter? Is prototyping expensive? Those questions will be topic and real examples will be shown.

Bringing a computer is highly recommended.
The good, the bad and the data Do you remember the days before DevOps? The days when developers and system admins alike just

concentrated on the application and servers and the data was mere byproduct of the application? Data has become someone's content, someone's privacy and a gold mine of interesting trends. Data is no longer the byproduct of an application. This change has effect on the lives of the developers and as well as the lives of those who operate the systems. Have you seen this shift?

How do you handle it when it hits you? Data protection and privacy are hot topics even outside the debate around national 3 letter acronyms.

Unethical Hacking Assembly Every new redefinition of hacker ethics divides individuals in two groups, good and bad.

The hacker communities finally got rid of the old mass-media image of the "bad hacker". Who is the new "bad hacker" then? What practices and approaches are excluded by the new ethical paradigm?

We propose a "mutual aid" (AA-style) group to share thoughts and experiences of being bad hackers today.

WLPress - volunteer-organized news WikiLeaks-Press is a volunteer-organized and news aggregation website endorsed by WikiLeaks. Since 2011 we have researched the material that has been published by WikiLeaks. This includes Cablegate, the Iraq and Afghan War logs, the GIfiles and the Spy Files. There is a small core team of volunteers doing research and a larger group of volunteers who occasionally help out.

In this session we will explain the motivation behind the website, what we have published in the past and how you can find out how much fun researching the WikiLeaks material is!

We are not official representatives of WikiLeaks – official WikiLeaks statements and information will only ever be given out over the WikiLeaks website and the @wikileaks twitter account.

There are 155 registered self-organized sessions.

Your Self-organized Session goes 30C3

On this page you can find a list of planned self-organized sessions by participants of the 30C3 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 30C3 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.

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.
