I want to use {JetBrains tool} in my talk but I don’t have a license. Can you help?**

We have free trials available that you can download. In addition, all accepted speakers get a 1 year Personal All Products Pack subscription on us.

Do you have any other tips?

We receive many submissions and only have a limited series of slots. As such, please consider the following tips when submitting your talks, which can work in your favour.

Talk Title – We go through all talks independently of the title, but there’s no denying that a catchy and interesting title plays favourably. At the same time, make sure that the title aligns with your abstract.

Abstract – Make it concise and to the point, but don’t make it too concise. An abstract that is just 2 sentences, will most likely stand little chance of getting accepted. We don’t expect you to write an essay but please try and provide information on what you’ll be covering in your talk and what the key learning points / takeaways will be for the audience. If you’re submitting a topic that may be popular, try and find an angle that would distinguish yours from others.

Try to refrain from "don’t use this code in a real application" talks. Illustrate how something could be used in a production code base, and what the audience should know to be successful with a technology.

Level – Please try and accurately define the level of your talk.

Session Length – Sessions are 60 minutes long, including QA (which is optional)

Thanks in advance for submitting your talks!
