SeaGL (the Seattle GNU/Linux conference) is a free—as in freedom and tea—grassroots technical summit dedicated to spreading awareness and knowledge about free / libre / open source software, hardware, and culture.

SeaGL strives to be welcoming, enjoyable, and informative for professional technologists, newcomers, enthusiasts, and all other users of free software, regardless of their background knowledge; providing a space to bridge these experiences and strengthen the free software movement through mentorship, collaboration, and community.

SeaGL’s first year was 2013.

Lightning Talks at SeaGL 2021!
August 24, 2021

We’re incredibly excited to announce that we’re hosting lightning talks at SeaGL this year! Think of this space as a great opportunity to learn about fun topics, or even present your own talk. It’s a great way to get comfortable with speaking to an audience or to explore the kernel of an idea that could become a full-length talk at SeaGL 2022!

The lightning talks will be a series of 5 minute talks which will be pre-recorded - meaning that we can accommodate speakers from all over the world! We’re looking for any community focused talks. A few examples are:

  • Tech examples: Event organization, coding, design, documentation, open source, etc.
  • Non-tech examples: non-profit work, hobbies/programs (eg. community gardens), sports teams, theater, etc.

Our one request is that there are no promotions of any kind - meaning, please no video resumes, no company/product promos, etc.

We’re looking forward to hearing from you, our community. Please submit your talk ideas as soon as possible, as we will be reviewing them on a rolling basis.

Unintended emails being sent
August 23, 2021

Hello SeaGL community,

Some of you might be getting multiple emails from us. We want to apologize for the unintended mailings. Some changes were made to past conference schedules as part of a general clean up. We were working on an archive page that was disconnected from OSEM, our conference software. Unfortunately, there were no notifications from OSEM that emails were being sent to the community.

We are currently working on a shim to stop any emails from going out until all updates are done. Thank you so much for your patience. You can reach out to us on our usual communication channels.
