September 2 – 4, 2026
Symmetry Investments and the D Language Foundation want you to join us in London September 2 – 4 for the 2026 edition of the D Programming Language Conference . Together with our friends at Brightspace Events and CodeNode, we're working to bring you three days of fun, insightful conversations, and educational talks.
Can't be there in person? No problem! Join our livestreams and ask questions of the speakers at any time during each session. Find the links right here a week before kick off.
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.
If you're worried about the airfare or flight cancellations right now, our event planners have compiled links to information sources that should reassure you can book travel to the UK without worry, though it's better to book sooner rather than later to avoid higher prices.
Whether you’re a seasoned DConf veteran or joining us for the first time, we can’t wait to welcome you to London!

We’re excited to welcome several first-time DConf speakers this year. We're happy to see some DConf regulars coming back for more. Of particular note, Vladimir Panteleev, who last spoke at DConf 2017, is returning with a bang, presenting not one, but two heavy-duty talks.

Walter Bright is the creator and first implementer of the D programming language and has implemented compilers for several other languages. He’s an expert in all areas of compiler technology, including front ends, optimizers, code generation, interpreter engines, and runtime libraries. Walter regularly writes articles about compilers and programming, is known for engaging and informative presentations, and provides training in compiler development techniques. Many are surprised to discover that Walter is also the creator of the wargame Empire, which is still popular today over 40 years after its debut.
10:30 LLMs in the Standard Library
by Adam Wilson [Show Details]
Audience: All
Duration: 40 minutes
This talk will examine the integration of Large Language Models (LLMs) into the development process for Phobos 3. We will outline the motivations for adopting LLMs in this foundational component of the D ecosystem, the process and tools we recommend for developing Phobos 3 with an LLM, an overview of the associated legal considerations, the rules established for their responsible use, and our long-term vision for LLMs as a core element of the broader D programming environment.
Adam is an independent contractor with over 24 years of software development experience specializing in libraries and tooling for high performance web services. Adam’s resume includes start-ups, consulting, and even a few years at Microsoft working on Office 365. He is currently using D to create tooling that supports the development and deployment of a SQL-based web-service.
11:30 AI - The Five Stages of Grief
by Robert Schadek [Show Details]
Audience: All
Duration: 40 Minutes
LLMs are changing things; how, what, and for whom is still vague. Many of the reactions to the change seem to be reflected in the five stages of grief: Denial, Anger, Bargaining, Depression, and Acceptance. This talk will take a humorous look at the changing landscape of software engineering, what is possible with AI, what is still difficult, potential ideas on how to cope with all of this, and how it might relate to the D programming language and its future.
