Talks will be released before the conference day, watch them as soon as possible! And: no registration fee.

Until February 8: talk proposals

Propose your talks by sending them to Feel free to drop in #guix on to discuss what you would like to talk about before submitting. :)

You can choose one of the following formats:

In addition to the format you would like to choose, please describe your session with 10 lines or more (for lightning talks, at least 1 sentence).

Once you have sent your proposal, you will be notified in the following days whether your talk will be part of the Guix Days. Submit earlier to get more time to prepare your session!

Even for live presentation, please prepare a back-up pre-recorded talk, so we can play it if you cannot attend or have a technical problem during the Guix days. The deadline for short presentations (5 minutes) is February 16.

We welcome all kinds of topics from the community, especially your own experience with Guix, your cool projects that involve Guix in some way, infrastructure around guix (translations, continuous integration, ...), and any subject you feel should be discussed during the conference.

We particularly encourage people who consider themselves part of a group underrepresented in Guix and the broader free software movement to submit a talk. Do not hesitate to get in touch with the organizers at if unsure or if you would like guidance on how to prepare your talk.

Please make sure your talk is accessible to a non-expert audience, for instance by explaining the general context before diving into technical descriptions, and by avoiding acronyms and jargon.

We accept talks in languages other than English provided English subtitles are included.

Have a look at the topics from the last conference for ideas, but don't hesitate to innovate in your proposals!

February 8 (or before) – 12: prepare your session

The aim of the pre-recorded talks is to demonstrate new features, what you are hacking on, introduce the subject for easing the live question and answer sessions or BoFs. These pre-recorded talks should be 15–45 minutes long. Feel free to ask if you need help with the recording.

You are free to choose whichever storage platform you want (e.g., your own website, a PeerTube instance, a Nextcloud instance, etc.), but we will need to have access to the original file so we can publish it later on Your video must be released under a license that at least allows anyone to copy and share it, for any purpose.

You will have to release the video publicly before February 12, so everyone has a chance to see it before the conference. If you are not able to do so (for instance your server cannot handle a huge load), you can alternatively send us a private link to the video and we will upload it on If you decide to do so, you will need to have the video ready by February 10.

February 12–18: watch the talks

But don't miss the Fosdem conference either!

Be sure to watch the pre-recorded talks before the conference. There will be no presentations on the 19 nor 20.

February 19–20: participate

Coming soon! Stay tuned.

About GNU Guix

GNU Guix is a transactional package manager and an advanced distribution of the GNU system that respects user freedom. Guix can be used on top of any system running the Hurd or the Linux kernel, or it can be used as a standalone operating system distribution for i686, x86_64, ARMv7, and AArch64 machines.

In addition to standard package management features, Guix supports transactional upgrades and roll-backs, unprivileged package management, per-user profiles, and garbage collection. When used as a standalone GNU/Linux distribution, Guix offers a declarative, stateless approach to operating system configuration management. Guix is highly customizable and hackable through Guile programming interfaces and extensions to the Scheme language.
