Since 2013, DConf has been the primary 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 both submissions for standard talks and signups for lighting talks for DConf ’26.
Lightning Talks
Lightning talks are short, five-minute presentations presented back-to-back by multiple speakers. When a speaker's five minutes are up, the emcee rings a gong and the next speaker takes the stage.
This year, we'd expanding the number of lightning talk sessions from one to two or three. As such, we're accepting signups early. If you're planning to attend DConf ’26 and would like to present a lightning talk, simply email social@dlang.org at any time before the conference. Once you've registered for the conference, we'll add your name to the list of lightning talk speakers. (Registration opens at the end of March.)
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 24 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 ’25 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:
Language techniques enabled by the D programming language
Tools and techniques for maximizing productivity when working in D
Experience reports on using D in the real world, professionally or as a hobby
Under the hood looks at compiler and standard library implementation artifacts
Hot topics such as safe deterministic memory management, migrating from other languages, or community engagement
Deep dives into D projects, their APIs, architecture, and implementation details
Research reports by students doing research on or using the D language
Don't feel constrained in topic or format. Follow your inspiration where it leads and tell us about it!
Selection Criteria
Standard talks should be no longer than 40 minutes and no shorter than 25 minutes. Additionally, we will evaluate submissions according to the following criteria:
Relevance: Is the topic interesting to DConf attendees? Will coverage be beneficial? Is it building on tried and true ideas, or blazing new trails?
Coverage: Does the proposal cover the topic in depth? What are the main insights dispensed by the submission?
Organization: Is the submission well organized? Will the audience tune into the narrative?
Novelty and Originality: How new and noteworthy is the material? Previously published material is acceptable provided it hasn’t yet
reached a wide audience within the D community.
Bottom Line: What’s your session’s takeaway? How is it going to improve the attendees’ knowledge, outlook, and inspiration?
Standard Submission Guidelines
We expect submissions in either plain text or Markdown. Please do not send PDF, DOCX, etc. All submissions should be directed to
social@dlang.org
and should include:
Abstract: the "elevator pitch" of the talk, in one paragraph
Extended Description: an extended abstract including any details you believe are relevant for evaluating the submission
Brief Speaker Biography: including a summary of the speaker’s expertise relative to the talk topic
We can’t wait to see what you send us!
Registration
GBP rates are based on the HMRC Exchange Rate for the current month. Note that this rate is static for the month and will most likely differ from the rate used by PayPal or your credit card company. You may find the USD PayPal link to result in a lower or higher charge on your GBP credit card than the GBP link.
A 20% VAT is added to the base registration rates.
General Registration Base Rate: $350 (£261.96)
At a base rate of $350, the total with 20% VAT is $420 (£314.35). General Registration closes at 11:59 UTC on September 2.
The student rate is a fixed $100 + 20% VAT, or $120 (£89.81) until General Registration closes. If you qualify, please contact social@dlang.org for details on how to take advantage of this discounted rate.
Hardship Rate
If you would like to attend DConf but cannot afford any of the above rates, we are willing to offer you a special hardship rate. This is a discount on registration only. We cannot assist you with transportation or lodging. Please contact social@dlang.org to explain your situation, and we’ll provide you with more details.
Please be aware that by attending the conference, you acknowledge that you are responsible for any property that you bring to the venue and that neither the D Language Foundation nor its sponsors can assume any responsibility for damaged, stolen or lost property belonging to the attendees.
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 take place on the ground floor in the CTRL room. We’ll have the entirety of the ESC area downstairs to ourselves, where attendees can relax, chat, or play games 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.
Each 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.
In the abasence of of a pub hire, the official gathering spot is the Travelodge London Central City Road a short walk north of the venue. The bartenders there have been good to us in the past. No matter how many of us have shown up, they’ve kept up with us quite well. Drop by after dinner and talk into the night!
If and when we obtain funding for a pub hire, we'll update this space. Stay tuned!
Sponsors
DConf ’26 is hosted by our friends at Symmetry Investments. With offices in Hong Kong, Singapore, London, Jersey, New York, and the Cayman Islands, Symmetry employs D in their investment management mission. This is the sixth 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.
