August 19–22, 2025

Symmetry Investments and the D Language Foundation invite you to join us August 19–22 in London for the D Programming Language Conference 2025. We’re happy to be working once more with our friends at Brightspace Events and CodeNode to bring you another four days of fun, insightful conversations, and educational talks.

Since 2013, DConf has been the annual event bringing together D programming language enthusiasts and experts from across the globe for the rare opportunity to mingle offline in the real world. We enjoy interacting with each other online, but there's no substitute for the chance to share ideas face-to-face between conference talks, over dinner, or in a local pub.

Whether you’re a seasoned DConf veteran or joining us for the first time, we can’t wait to welcome you to London!

Call for Submissions

Coming up with an idea for a talk is as simple as the way you use D. Just look at your code, and it makes a presentation...
— Ali Çehreli, DConf Online 2020

We are currently accepting submissions for DConf ’25. If you have an idea for a talk, demo, or panel, don’t hesitate to submit it! We’re interested in anything and everything related to the D programming language. We will review all submissions submitted by May 4 AOE.

Never presented at a conference? Don’t let that stop you! Several D community members have given their first conference talks at DConf. Our community is always welcoming and ready to make you feel at home.

Not sure what to talk about? As Ali pointed out in one of his DConf Online 2020 Q&A sessions, if you’re using D now, you probably already have material for a potential talk.

If you need inspiration, visit the DConf ’24 Schedule to see what sort of talks were presented, then follow the links in the menu bar to past conferences for more. Any topic related to D is a potential talk, such as:

Don't feel constrained in topic or format. Follow your inspiration where it leads and tell us about it!

Venue

Our DConf ’25 venue is CodeNode, a space in Central London specifically designed for tech conferences. It’s conveniently located close between Moorgate and Liverpool Street stations and is a 10–15 minute walk from Old Street Station to the north.

Our presentations will happen on the ground floor in the CTRL room, and we’ll have the entirety of the ESC area downstairs to ourselves, where attendees can relax, chat, or play table tennis or foosball between talks.

Accommodations

We advise you to book a hotel room early, as rates tend to go up the closer to your travel dates. If you want to attend but aren't yet certain you'll be able to, consider booking an option that allows refundable cancelation. That's usually more expensive, but better than giving up a refund if you can't make it.

There are several budget hotels in easy walking distance. The following are some options that, according to Google Maps, are less than a 20-minute walk from the venue. Some of them are near an underground station that is one stop away from Moorgate or Liverpool Street stations. Click a link to see the walking route(s) between a hotel and the venue. On the map, you’ll find links to reserve a room. Note that most attendees generally stay at the Travelodge London Central City Road.

BeerConf

Every evening during the first three nights of DConf means only one thing: BeerConf! Ethan Watson coined the term in 2016 for our evening gatherings in a designated spot at every DConf. We've sometimes been able to hire pub space for BeerConf and sometimes have had to gather at a local hotel.

As of now, all three nights of BeerConf for DConf ’25 are to be located at the Travelodge Central City Road a short walk north of the venue. If we are able to obtain funding to hire space at a pub, we'll post an announcement in the D Forums and update this page.

Sponsors

DConf ’25 is hosted by our friends at Symmetry Investments. With offices in Hong Kong, Singapore, London, Jersey, and the Cayman Islands, Symmetry employs D in their investment management mission. This is the fifth time they’ve sponsored DConf, and we are thankful for their continued support. They are also the sponsors of the Symmetry Autumn of Code, an annual event that, since 2018, has provided experience to emerging programmers while enhancing the D ecosystem. We couldn’t be more excited to bring DConf to London once again with Symmetry’s support.
