39C3 — did someone say halfnarp?

Thu, 06 Nov 2025 17:00:00 +0200

In eager anticipation of 39C3, the dozens of curators in our six content teams have been working hard over the past few weeks: they have sent out invitations, evaluated submissions, written letters, researched, compared, created and discarded common themes, refined and tied up their loose ends, sorted, evaluated, and discussed submissions. Finally, they were able to distill the 763 submitted and invited talk proposals down to 164 and put together a plan that we are all convinced will provide us with an informative, entertaining, and memorable program on stage.

But now it’s your turn: In two weeks, we want to build a complete program from the still unsorted list of talks, and we need your help again! Since most of the speakers have now confirmed their talks, you can help us draw up a schedule for the days and rooms that will allow as many of you as possible to experience the talks live in the halls with many like-minded people – without having to choose between two or more that interest you.

To do this, simply jump into the 39C3 halfnarp, get an idea of what’s on offer, select the talks that interest you, and click “Submit.” We will then combine your list of preferences with those of everyone else, do a little math, and will get warnings if we were to schedule two or more talks at the same time that too many of you want to see.

Later, you can even import your list into Hub, your calendar, or the apps. The clusters you form will be used by the media.ccc.de team to show suggestions for further viewing, and you can rightly claim to have been an important part of the schedule selection.

Fahrplan nach Euren Wünschen: Let’s do the halfnarp – agaaaaain!

Thu, 22 Nov 2018 18:31:21 +0000

Tl;dr: Please read the FAQ and do the halfnarp!

It’s that time of the year again: We’re going to gather in Leipzig at the Chaos Communication Congress with our fellow mad hatters and get lectured. But before we can have the time of our lives, we need you, you, you to make the Fahrplan as frictionless as possible – we have to shuffle around a record-breaking number of around 160 lectures.

Without further ado, we present the 35C3 halfnarp and would kindly ask you to lose yourself in the options, then mark and submit the lectures you plan to attend. We’ll take your data into account when scheduling lectures and later provide a recommendation web depending on the correlations we find. Our main goal is to make sure that certain most-clicked lectures will not happen at the same time. If you have any questions about the halfnarp, please see our FAQ.

And to make halfnarping even funnier for all those pausing Diablo Immortal on their phones, the new narpr(beta) feature allows for some easier interaction: it’s just a swipe to the left and then a swipe to the ri-i-i-i-ight – to mark your favourite things.

33C3 halfnarp: The talks that ‚work for us‘

Fri, 18 Nov 2016 16:56:07 +0000

The 33C3 content committee is proud to announce a lecture selection that ‚works for us‘. Our five hard-working 33C3 track teams have hand-picked a set of around 150 excellent lectures to be formed into the best four day, six track programme possible.

Having to select talks from an impressive lot of more than 500 submissions was a hard and sometimes frustrating task. But we have been amazed by the overwhelming interest in volunteering to present at 33C3. We’re thrilled to see that support and enthusiasm to contribute to this year’s event is as high as it ever been. Some speakers even refuse to accept a free ticket!

With this post, we want to do three things: Whet your appetite for our programme, ask for your help in putting together a collision-free schedule, and call for your workshops and self-organized sessions.

First, we present: The halfnarp https://halfnarp.events.ccc.de/.

In the halfnarp, you’ll find a list of all re-confirmed talks for each track (note: around 15 lectures are not yet re-confirmed, if you’re a speaker, please check your spam folder ;). You might notice that we offer a new track ‚Space‘, simply because we think all hackers should absolutely make space ‚work for them‘.

Second, we ask that you to help us put together a collision-free schedule that ‚works for you‘:

Select all lectures you would like to attend.
Press submit.
That’s it, there’s no step three. We’ll do the rest.

You can modify your choice at any time (don’t forget to press Submit again), or share it with your friends.

Third: The vast majority of submissions did not make it into the curated lecture programme. But that does not mean they wouldn’t be interesting to the crowd at 33C3. We invite you to present your ideas in lightning talks, gather in your assemblies or even get hands-on with a self organized session.
