Registration is now open!

This is the first time we are charging a $10 fee for registering to attend CHAOSScon. We'd like to explain. At CHAOSScon NA 2019, interested people were discouraged from coming because they were on a waitlist but we had many empty seats due to no-shows. By charging a small amount, we hope to limit no-shows. The ticket fee will go towards providing coffee, tee, snacks, and serve lunch.

Important Notes

  • One complimentary pass for the event will be provided per submission.
  • Do not propose sales or marketing pitches. Do not include unlicensed or potentially closed-source technologies when preparing your proposal. These talks will be rejected due to the fact that they take away from the integrity of our events and are rarely well-received by conference attendees.
  • All accepted speakers are required to submit their slides prior to the event.

Preparing To Submit Your Proposal

While it is not our intention to provide you with strict instructions on how to prepare your proposal, we hope you will take a moment to review the following guidelines that we have put together to help you prepare the best submission possible. To get started, here are three things that you should consider before submitting your proposal:

  1. What are you hoping to get from your presentation?
  2. What do you expect the audience to gain from your presentation?
  3. How will your presentation help better the ecosystem?

There are plenty of ways to give a presentation about projects and technologies without focusing on company-specific efforts. Remember the things to consider that we mentioned above when writing your proposal and think of ways to make it interesting for attendees while still letting you share your experiences, educate the community about an issue, or generate interest in a project.

When you are ready: Submit your proposal.

Session Types

You will need to choose a session type when submitting:

  • Lightning Talk (5 minutes)
  • Regular Session (20 minutes)
  • Hands-On Workshop (approximately 60 minutes)


This is your chance to sell your talk to the program committee, so do your best to highlight the problem/contribution/work that you are addressing in your presentation. The technical details are still important, but the relevance of what you are presenting will help the program committee during the selection process.

This is the abstract that will be posted on the website schedule, so please ensure that it is in complete sentences (and not just bullet points) and that it is written in the third person (use your name instead of I). Your abstract is limited to 1500 characters (~200 words).

Example: The proposed presentation will provide an overview and current status of the Linux Foundation's CHAOSS project. This will include a discussion of the CHAOSS project workgroups, with a particular focus on the technical advances that are being done with respect to understanding the growth, maturity, and decline of an open source project. The presentation will conclude with a discussion of future work of the CHAOSS project, as well as ways to become involved in the project.


Describe who the audience is and what you expect them to gain from your presentation. Your description is limited to 1500 characters (~200 words).

Example: The audience for this project includes organizational members who are interested in better understand the growth, maturity, and decline of the open source projects with which they are engaged. This could include corporate participants, community managers, and members from supporting foundations.

First Time Submitting? Don’t Feel Intimidated

This is a friendly audience and an excellent way to get to know the community and share your ideas and the work that you are doing, so we strongly encourage first-time speakers to submit talks. In the instance that you aren’t sure about your abstract, reach out to us and we will be more than happy to work with you on your proposal.

How To Give a Great Tech Talk

In the instance that your talk is accepted, we want to make sure that you give the best presentation possible. To do this, we enlisted the help of seasoned conference speaker Josh Berkus who has prepared an in-depth tutorial on “How to Give a Great Tech Talk”: Part 1 and Part 2
