🎤 About the talks 🎤

Discovering Qt: A Comprehensive Introduction to the Versatile C++ Framework

Qt is a powerful, cross-platform C++ framework for creating high-quality, high-performance UI applications for desktop, mobile, embedded systems, and more.
This presentation delves into the history and evolution of Qt, its core features, and its broad range of applications across industries. From its declarative UI language (QML) to its extensive module ecosystem, we’ll showcase what makes Qt an essential tool for modern development. This presentation is designed for those new to Qt or looking to explore it further.

Alexandra Betouni is the CEO of Extenly, a consultancy company specializing in UI development solutions since 2019 and the organizer of the annual QtGreece event. With experience on major projects like Mercedes-Benz’s MBUX, Alexandra has authored Qt and QML online courses and was honored as a Qt Champion for 2024, highlighting her dedication to the Qt community.

Trivium, A Library For Symbolic Metaprogramming in C++

Template metaprogramming (TMP) code tends to be unfriendly to humans. The code is generally neither easy to read nor easy to write. The Trivium framework gives a solution to this problem by organising TMP indirectly by the means of Trivium Lisp, a symbolic domain specific language (DSL) for metaprogramming.
Metaprograms are not encoded directly in C++, but as symbolic expressions in Trivium-Lisp. This indirection allows us to hide all the "ugly parts" of TMP in the implementation of the Trivium Lisp interpreter, which is a "universal" C++ template metaprogram to interpret Trivium Lisp expressions as C++ types.
The metaprograms themselves, written in Trivium Lisp, become as clean and as simple as programs written in any reasonable functional language, such as Haskell or Lisp.
