Submission process

Each submitted talk will be examined by at least three reviewers from the Program Committee.

We consider talk applications according to the following guidelines:
  • The topic's relevance – you are going to discuss things that participants of the conference find useful not only yesterday but today and in the future. In addition, the topic of your talk corresponds to the theme of the conference, and the talk's content matches the stated topic.
  • our talk dives deep into the details of the stated topic – there is no need to talk about yet another Hello World (unless you think it's a new, not widely known, but very promising technology).
  • Originality — there is technical novelty in your talk; the content of your talk either hasn't been published before or presents a well-known topic / problem in a different light.
  • Practical applicability — the talk is important from practical point of view, you not only cover the existing problems/solutions, but also share your experience.
  • Speaker's expertise and publicity.

In order to submit your talk, please, fill in the form below: we kindly ask you to pay as much attention as possible while doing that, because we'll consider your application based on the information provided below. If you require help while preparing your talk, we'll do our best to help you make a good talk.
If you've already submitted your talk, yet haven't heard from us during one week, then something went wrong. In this case, please, contact us via email program@jokerconf.com.
If you’d like to give a talk at the conference, please, read the memo for speakers.



Joker 2020 conference goes online, which means that it should become more interactive and dynamic than any other online event.

This summer we held our conferences online and got useful experience. We saw that sessions with two to three active participants help engage the audience and keep their attention much better than sessions with one speaker only. Therefore, we now try making most of the talks paired or interactive.

Before submitting your application, please, consider whether you are ready to adapt your talk to the online format. We will try to find a co-speaker or an expert to keep up the pace of the talk and engage the audience in dialogue so that you do not have the impression of "talking to the monitor".

Are you ready? Check the box next to the format in which you want to give a talk:

Whom would you like to see as your co-speaker?
Please, tell us, is there anyone who could help you during your online talk? If no one pops in your mind, could you please describe an ideal partner for your online session, and we'll do our best to find such a person for you.
The title should be clear and reflect the essence of the talk. Remember: brevity is the soul of wit.
Include enough details about your talk, but be concise and clearly state: describe technologies that will be covered, purpose of the talk (problem and its solutions, etc.), target audience, audience takeaway.
About 20 points that represent main ideas of the talk.

We reserve the right to edit lexical and grammatical flaws in texts you will send.
