In light of the COVID-19 situation, IWP9 will be rescheduled. Right now, we don't know how bad things will get or how long it will take to stabilize. As a result, we don't have a new date yet. We will announce it as soon as we do.

Because the event will still be running, we are still accepting papers. We will be extending the deadline until at least June 1st. Because we realize that attendance may be difficult given the lack of firm dates and the sudden changes in venue, we will be accepting remote presentations.


The workshop will bring together researchers, developers and students working on Plan 9 from Bell Labs and related systems, to work on a wide variety of projects.

The workshop will be split into two sections: Talks and a hackathon. The talks will cover the state of the Plan 9 world. The hackathon will improve it. The hackathon will not have talks, tracks, prizes, or a schedule. Instead, you will attend in order to work for a straight stretch of time on the projects that you find interesting, in the same room as the people that you need in order to discuss ideas and get your changes in the source tree.

The hackathon portion will be self directed and unstructured. Bring personal annoyances, bugs, experiments in distributed systems, hardware that needs drivers, applications that you're missing, or any other projects that you'd like to work on. Or team up with someone else and learn from them as you help out.

All systems in the Plan 9 family are welcome.

Paper Submission

Papers may cover any topic related to Plan 9 or related systems. We'd love it if your submission comes with working code to show off, but work in progress, new and interesting challenges to consider, or approaches to think about from outside the Plan 9 world are also encouraged.

Send your paper to iwp9paper at iwp9.org. It should be no longer than 15 pages. PDF or PS format is strongly preferred. If applicable, also attach the LaTeX or Troff source code. Please make sure to include the e-mail address of the contact author. We will confirm that we received the paper via email within 48 hours.

The talks should typically run for 45 minutes, with some time for questions at the end. Talks will be recorded, and posted on the site

Papers should be visually similar to those found at /sys/doc/9/ in order to compile a homogeneous proceedings book. For an example, see this paper. These macros and this mkfile can be used to duplicate this look.

You may submit multiple papers. The accepted papers will be published on this website after the conference. With speaker permission and review, recorded talks will be posted on youtube and linked to from this website.

Program & Proceedings

We'll proceed to program.

A schedule of talks will be posted after papers are accepted.
