Day 1: Thursday (18.09)

10:00 Ian Barker

Dead? You have definitely used Pascal today and you didn't even realize
It's a weird fact that people go out of their way to reassure me that "Delphi is dead". Yet these same people have definitely used a Pascal or Delphi program today and didn't even notice. Probably more than once. Every. Single. Day. In a time when we are trumpeted by This Week's Best Ever JavaScript framework (which overcomes the problems with last week's JavaScript hero) and where AI is an answer to a question nobody asked - why, after more than 40 years, is Object Pascal still around at all and WHEN WILL IT DIE?

• Back to timetable

11:00 Stefan Glienke

A quick introduction to Spring4D for everyone
The Spring4D library is an enhancement to the Delphi RTL. It offers a large variety of interface based collection types, multicast events, the nullable type and much more. Furthermore it provides the most advanced dependency injection container for Delphi.

13:30 Andrea Magni

Building multi-tier applications with Delphi
Delphi has evolved over the last 30 years. Have your applications kept up? In this session, we’ll explore how to build modern, maintainable, and scalable multitier applications using Delphi, with a strong focus on REST based architectures. Whether you're maintaining legacy code or starting fresh, we'll walk through practical approaches that leverage Delphi’s powerful capabilities to build services, structure data access layers, and integrate seamlessly with modern frontends and third-party systems. You’ll see how to go beyond simple data exposure and adopt clean patterns, security best practices, and testing strategies that boost productivity and bring your Delphi codebase into line with current software development standards. This session is your opportunity to take full advantage of what today’s Delphi has to offer.

• Back to timetable

14:30 Arnaud Bouchez

The Leopard and the mORMot
While the leopard is known for being a shiny and swift animal, the marmot is more of a fluffy fearful prey. But in the world of object-oriented Pascal, the combination of the two can be formidable. While mORMot runs well with Delphi, it's with FreePascal and Lazarus that it really comes into its own, particularly for creating server applications from existing Pascal code.

16:30 Andrea Magni

Delphi language features
Delphi has come a long way from the Object Pascal you first learned. Today’s language includes powerful features that make your code cleaner, safer, and more expressive without losing the simplicity that made Delphi so productive in the first place. In this session, we’ll dive into the most impactful language enhancements of recent Delphi versions: inline variable declarations, type inference, records with methods and operators, anonymous methods, generics, class helpers, extended RTTI, and more. You’ll see how these features can dramatically reduce boilerplate, improve readability, and enable more modern design patterns. Whether you're working on large-scale applications or smaller utilities, this is your chance to rethink how you write Delphi code, embracing techniques that bring it closer to the productivity and elegance of today's best languages, while staying true to Delphi’s roots. It’s time to rediscover the Delphi language!

17:30 All Speakers

Expert Q&A
In this slot, participants have the chance to meet speakers and contributors in small groups for direct, in-depth conversations. Each expert hosts a dedicated room where attendees can drop in, ask questions, explore ideas, or discuss specific use cases in an informal setting. It’s a unique opportunity to go beyond the talks and connect directly with the people behind the tools and projects.

Day 2: Friday (19.09)

09:00 - 12:00 Stefan & Eduard Appelhans, Michalis Kamburelis

From 3D Design to CNC production – A Real-World Object Pascal Showcase
This session demonstrates how Object Pascal/Delphi can serve as the basis and connecting element from digital design to real-world production. Using a practical example from Sorpetaler Fensterbau, the showcase traces the process from IFC-based 3D modeling (FreeCAD, Blender, Castle Game Engine) to window construction using the company's monolithic Pascal application ("Zentrale") and finally to the CNC-controlled manufacturing of a wooden window component. The session includes a live demo of a CNC machine producing a part, followed by a guided walk through Sorpetaler’s production line.

13:30 Mattias Gärtner & Michael van Canneyt

Free Pascal & Lazarus – What's our future?
This session offers an update on the latest developments in Free Pascal and Lazarus, including insights into the just-released Lazarus 4.0 and key changes in the new Free Pascal version. Attendees will learn about the introduction of Fresnel and the new CSS Inspector, as well as get a first-hand look at the current roadmap for both Lazarus and Free Pascal. An essential session for anyone working with or interested in the future of open-source Pascal development.

• Back to timetable

14:30 Panel: Delphi and Lazarus

Delphi and Free Pascal / Lazarus – A Conversation About the Future
This panel brings together key voices from both the Delphi and Free Pascal / Lazarus communities to explore the current state and future potential of Object-Pascal-based development. Ian Barker (Embarcadero) and Andrea Magni will represent the Delphi world, while Michael van Canneyt and Mattias Gärtner bring insights from the Free Pascal and Lazarus projects. Moderated by Detlev Overbeck (Blaise Pascal Magazine), the discussion will cover areas of convergence and divergence, collaboration potential, technical developments, and the shared challenges of keeping Pascal relevant and innovative in a fast-evolving tech landscape.

16:30 Danny Wind & Michael van Canneyt

AI Integration in Object Pascal: Introducing the MCP Framework
In this session we will introduce the MCP framework developed in Object Pascal. MCP – short for "Model Context Protocol" – enables AI agents to interact with tools via a standardized protocol. Traditionally, tools were tightly integrated into AI agents, but MCP separates concerns: the MCP server hosts executable tools, while the MCP client (the AI) sends commands. The server can describe its available actions in a standardized format, making dynamic and flexible interaction possible. This talk explores the core concepts, architecture, and potential of MCP for AI integration in Pascal-based systems.
