Register

ORConf is free to attend. If you are able to, please help running the event by considering a "Pay what you want" ticket with an donation. If you are attending ORConf on behalf of their company are encouraged to donate in the form of a professional ticket. Please choose one option in the checkout process -- you do not need a "Free" ticket in addition to a "Pay what you want" ticket.

Submit a talk

Presentations are submitted through the Eventbrite registration interface.

Please make your submissions as early as you can, as the presentation slots are likely to fill up quickly.

We aim to give as many people as possible the opportunity to present their exciting work on free and open source silicon. To accomodate for that we will determine the duration of a full talk once all submissions are in. Historically, full talks ran for 10 minutes (plus time for questions). Lightning talks will be 3 minutes. The exact amount of time you'll get will be communicated on acceptance of your talk.

Code of conduct

We ask all ORConf participants to adhere to the the FOSSi Foundation code of conduct throughout the event.

Sponsors

ORConf is free to attend, but we aim to provide catering and the like during the event. ORConf is also a great way to get your company or brand in front of lots of engineers and hackers on the day, and thousands more through recordings of the event.

Please get in touch at orconf@fossi-foundation.org if you'd like to explore sponsorship opportunities.

A variety of sponsorship packages are available for this year's ORConf.

ORConf is organized by volunteers on behalf of the FOSSi Foundation. We are currently looking for more people to help out with arrangements and putting on the event, so please do email us if you would like to volunteer for during the event with setup, AV, or even just local knowledge so we can plan the weekend better.
