About the LJC Unconference.

The London Java Community (LJC) hosts a ‘unconference’ every year that allows developers to come together for a full day of discussions, sharing experiences, learning and spending time with our peers in the industry. This is the 13th unconference we’ve hosted and it’s most certainly the premier event of our user group. This year we’re hosting the event virtually for the first time!

What is an Unconference?

An unconference is a loosely structured, participant-driven meeting. It does not follow the traditional conference program structure. You decide what you want to talk about and which topics you want to discuss. The unconference starts with an empty schedule. No topics are mandated, no separations are made between “speakers” and “audience”. All participants work out a schedule by suggesting, planning, holding and evaluating sessions, collaboratively.

Introduction to the Day

09:30 AM

People, planet, clouds

by Holly Cummins

The world is changing. The cloud gives us dazzling computational possibilities, and … potentially uses a lot of energy. As climate change accelerates, where do we, as engineers, fit in? Are we part of the problem or part of the solution? How do we balance the needs of people against the need of the planet? Or can they be aligned?

Food and Drink

Your unconference ticket covers the best breakfast, lunch, coffee/tea & biscuits that the Compass group can provide! We’re making sure that we cater for vegetarian and vegan attendees also. You’ll also get access to our social event after the unconference which will start off with a tab behind the bar.


Our wonderful sponsor, IBM, have once again graciously and generously offered their wonderful South Bank office to host our unconference. It’s a modern space and has many rooms and corners in which we can relax and have meaningful discussions and conversations. For more information about the location, please see the address section below.


Unlike regular presentations, you won’t need slides, a laptop, or even a plan! It’s good for the person who submitted the session to spend the first few minutes talking about why they picked the topic and what they want to discuss. After that, everyone is a participant. You’re the speaker and the audience as we engage in meaningful discussion with the group. Being a part of the session is the best way to get the most out of your experience at the unconference.

Submitting topics

Anyone can submit a session. If you do, you’re not expected to stand up for 35 minutes and talk to a crowd. That’s more like what you see at traditional conferences. Think about this more as you moderating a topic which others are keen to express an opinion or learn more about.


They love it. Read what the previous attendees had to say!

Frequently Asked Questions

What is an Unconference?

An Unconference is an Open Spaces event. Here is an exerpt on Open Spaces events “What’s the best thing that happened at the last conference you attended? It’s very likely that you’ll remember one or more “hallway conversations,” or perhaps a “Birds-Of-A-Feather” session. An OpenSpace conference creates that experience for the entire conference, by ensuring that you are always having the most interesting conversation possible. The emphasis is on discussion, instead of listening to eyes-forward presentations.” You can read more here.

How does it work?

We start the day with an empty schedule. Sessions within the unconference are going to be determined on the day of the unconference by the attendees. Every attendee will have one piece of paper that they can submit a topic. They don’t have to submit anything, but they can. Topics will them be grouped and break out discussions can occur throughout the day around those topics.

What time does it start?

The unconference starts at 09:30. You should aim to arrive between 08:30-09:00 as registration can get busy. It will also give you plenty of time to get breakfast at the venue and chat with other attendees. Check out the schedule above to see how the day runs.

Do I need to prepare for sessions I’m running?

It pays to have a little preparation done, certainly providing a framework for the topic / discussion helps. We often find that a small handful of slides or a quick write up on a whiteboard helps frame an interesting discussion.

How do I get a ticket?

Tickets can be purchased here, or directly via eventbrite.

Is there going to be after unconference social?


Can I bring my kids / child?

We often have a few under 18’s keen to experience the unconference and they are more than welcome.  Anyone under 18 needs to be supervised by their parents / caregiver.

For the little ones there are no specific change facilities for toddlers or babies in the IBM centre.  Regular bathrooms are available.
