CFP closed at  October 25, 2018 12:10 UTC

For the second time we invite the international Ruby community into the south of Bavaria for a conference in the spirit of EuRuKo and eurucamp.

Set against the backdrop of the beautiful Alps at lake Tegernsee, we welcome Rubyists from all over the world to gather, have fun in the snow and talk about the future of Ruby, Rails and related technologies in a single-track community-run conference.

To get a feeling for our conference, check out the gallery with images from last year.

CFP Description

Thank you for your interest in speaking at Ruby on Ice 2019! Please consider the guidelines below to boost your proposal’s chances of being accepted. If you have questions or concerns you can email us any time at Please be aware that we follow the Berlin Code of Conduct at Ruby on Ice.

Talk and workshop format

Ruby on Ice is a single-track conference with eleven lecture-style presentations and two workshops in English. You can submit multiple proposals.

Talk slots are 45 minutes each (including questions, if you take any). We encourage you to plan for 30-35 minutes of presentation and to leave the rest of the time for questions.

Workshop slots are 3 hours each. The workshops will be in parallel with the Saturday afternoon activities – so if you choose to give a workshop, you will not be able to take part in the activities. Our team will help you before and during the workshop to get the required software installed on participants’ laptops and help participants debug technical issues. Participants are required to bring their own PCs.

Please contact with any concerns you might have before or during the CFP (especially if you’re a new speaker – we’re happy to help!). Selected speakers will also be assigned a mentor that will help you prepare a successful talk for the conference.


Ruby on Ice is a conference about Ruby, Rails and related technologies. We also welcome non-technical topics relevant to the life of a Ruby developer.
