Lectures
Jonathan Müller – Software Engineer @ think-cell Talk: Cache-Friendly C++ We all love std::vector\—but do we truly know why it’s usually the best choice? Jonathan will unpack what it means for data structures to be cache-friendly, starting from the basics of CPU caches, their benefits, and the performance traps they can create. You’ll learn how to structure your programs and data to make the most of cache hierarchies, what data-oriented design really means in C++, and how to avoid common pitfalls that lead to slowdowns.
Sándor Dargó – Senior Engineer @ Spotify Talk: Strongly Typed Containers How far should you go with strong typing in C++? Sándor explores the trade-offs and techniques of building strongly typed containers—from inheritance pitfalls and private inheritance to composition and open-source solutions. Learn when to bend STL’s design rules, and when to steer clear.
Marcell Juhász – Senior Embedded Engineer @ Zühlke Engineering Talk: Hacking and Securing C++ Marcell will walk us through the world of C++ vulnerabilities using a minimal embedded device as the playground. From buffer overflows to stack manipulation, you’ll see how classic attacks work in practice—and more importantly, how to prevent them with modern C++ techniques like RAII, smart pointers, and bounded containers. Expect hands-on examples that will leave you with a deeper understanding of memory safety and practical strategies to build robust, secure applications.
