Call for Presentations

Dyalog User Meetings are built around the community - and your contribution could be part of it.

We’re looking for talks that show how you use Dyalog APL. It could be solving tough business problems, exploring new technical directions, or experimenting with creative ideas.

Don’t worry if your project isn’t “finished” – the user meeting is a place to share experiences and spark discussion.

Why Present at a Dyalog User Meeting?

  • Share your expertise - share your work with an engaged audience.
  • Get feedback – benefit from questions, discussion, and new perspectives.
  • Connect with peers – meet other developers, researchers, and practitioners.
  • Inspire others – help shape how the community learns, teaches, and applies APL.
