LLC 2025 has come and gone, it was great to see you all again and there is always next year!

LLC is a "half open" conference. This means that while we're formally invitation-only, it's very easy to get an invitation!

All we ask for is that you have some interest in the Linux kernel from a technical perspective.

If you would like to join the conference next year, please use this contact form with a short summary of who you are, and your relationship (if any) with the Linux kernel. Assuming everything is fine you'll get an invitation link before the next conference, please register a few months before the set date.

Frey Alfredsson - kau

Tries to add structure to chaos, atleast during our meetings!

Hans Holmberg - westerndigital

Is on a quest in the blocklayer when he's not teaching about the linux kernel

The Lund Linux Conference (LLC) is a small, technical conference with focus on serving and building the local Linux community - a chance for Linux developers to meet, learn and get to know each other.

The community now stretches beyond Lund and we have a good bunch of people from Denmark as regulars, as well as people we’ve met from all over the world.

The idea for a conference in Lund was hatched, like all good conspiracies, over beer in a dungeon, during the 2013 Embedded Linux Conference in Edinburgh. After realizing that surprisingly many people from the Lund region were regularly going to the same Linux conferences all over the world, Hans pitched the idea to the rest of the Lundensians of doing a small, yearly event in Lund. How hard could it be? We did not know how to do this, but saw no real reason why this would not work out beautifully. At least it could cut down on travelling costs.

After meeting up with some old friends at the Linaro office in Lund over glüewine and home baked cookies, the first conference crew was quickly formed with people from Linaro, Intel OTC, Axis and Ericsson, and the first conference was held in May 2014. It turned out we had a lot of kernel developers in the area, gathering 40 people at the event. Afterwards, we immediately decided to do it again, bigger and better the next year... and the rest is history :)

We still really don’t know what we’re doing, but it seems to be working. The community is growing and we now have trouble squeezing in all the awesome content we receive every year. We’re keeping true to the first guidelines we established the first year - a single-track, invite only, kernel-centric, free event focused on (technical) content over form.

Despite the small effort and budget spent on LLC, to our knowledge, it is the best and biggest (but perhaps only) Linux kernel conference in the nordic countries.

LLC code of conduct 1.0

LLC is dedicated to providing a harassment-free conference experience for everyone. We do not tolerate harassment of conference participants in any form. Conference participants violating these rules may be sanctioned or expelled from the conference at the discretion of the conference organizers.

Harassment includes, but is not limited to:

Enforcement

Participants asked to stop any harassing behavior are expected to comply immediately

If a participant engages in harassing behaviour, event organisers retain the right to take any actions to keep the event a welcoming environment for all participants. This includes warning the offender or expulsion from the conference.

Event organisers may take action to redress anything designed to, or with the clear impact of, disrupting the event or making the environment hostile for any participants.

We expect participants to follow these rules at all event venues and event-related social activities. We think people should follow these rules outside event activities too!

Reporting

If someone makes you or anyone else feel unsafe or unwelcome, please report it as soon as possible. Conference staff can be identified by special badges and will introduce the whole conference. Harassment and other code of conduct violations reduce the value of our event for everyone. We want you to be happy at our event. People like you make our event a better place.

You can make a report either personally or anonymously.

Anonymous Report

You can make an anonymous report using this form.

We can't follow up an anonymous report with you directly, but we will fully investigate it and take whatever action is necessary to prevent a recurrence.

Personal Report

You can make a personal report by:

When taking a personal report, our staff will ensure you are safe and cannot be overheard. They may involve other event staff to ensure your report is managed properly. Once safe, we'll ask you to tell us about what happened. This can be upsetting, but we'll handle it as respectfully as possible, and you can bring someone to support you. You won't be asked to confront anyone and we won't tell anyone who you are.

Our team will be happy to help you contact hotel/venue security, local law enforcement, local support services, provide escorts, or otherwise assist you to feel safe for the duration of the event. We value your attendance.

Be excellent to each other! /Bill&Ted

Based on this anti-harassment policy
