Just like last time, our two conferences PyCon DE and PyData Berlin join up. We are looking into a ca. 50/50 distribution of the sessions.

How will the program look like?

The Program will be published end of February.

What about tutorials?

There will be 90-minute tutorials. The attendance is included in the ticket but space is limited for each workshop.

Lightning Talks

A lightning talk (LT) is a short presentation of maximum five minutes. To sign up for a lightning talk please put your name and topic on the whiteboard next to the registration desk. Signing up is first-come-first-serve basis. The queue is reset every day in the morning. You may talk about / present about (almost) everything except: no promotion for products or companies, no call for 'we are hiring' (but you may name your employer). Conference announcements are limited to one minute only. One LT per day per speaker only. Any speaker not having given a LT at the conference is ahead of anyone who has given a LT already.

Presenting at the conference.

We do encourage everyone to use gender neutral language at the conference. Please make sure to bring a HDMI adapter with you. We will update this section with venue specific information.

Presenting remotely?

The conference is an in-person conference. As international travel is disrupted still, we will accept a limited amount of presentations to be held remotely especially to give anyone in our community the chance to present no matter the location and travel options. We will contact remote speakers with details.

Are speakers invited to the conference?

Accepted speakers will be provided a complimentary ticket for all the conference - limited to one per submission accepted in total and limited to one per individual.

Please see the milestones when to expect to receive the complimentary ticket.

We do not cover any travel or accommodation costs.
In case of multiple speakers other presenters need to purchase a ticket please.

What if I have purchased a ticket and get a free speaker ticket later?

We will happily refund your ticket.

I have updated some information - but it does not reflect on the website.

We use a static website. All information is coming from Pretalx. The website updates regularily. Please be patient. The same applies for the speaker list on Twitter. Please do not write to help desk to request information changes, it's self-service, thank you.

What about internet during my talk?

There will be no guaranteed internet for the talks, try to avoid making your presentation depend on internet connections. Use internet at your own risk. Though we try our best briefing the providers - conference WiFi performance might not meet everyone's expectations.

Other Options to Present About a Topic

Lightning Talks

A lightning talk (LT) is a short presentation which must not be longer than five minutes. You may talk about / present (almost) everything with certain boundaries:

  • no promotion for products of companies, no call for 'we are hiring' (but you may name your employer).
  • conference announcements are limited to one minute only
  • one LT per person per conference policy: everyone who has not given a LT at this year's conference, yet, is ahead of you in the queue
  • keep it short, the shorter the presentations, the more people can give a lightning talk

To sign up for a lightning talk, please put your name and topic on the whiteboard close to the registration desk. Signing up is on a first-come-first-served basis. The queue is reset every day in the morning.
