C++ Meetup in Budapest, Hungary 2025

The next Budapest C++ Meetup takes place on Tuesday, October 21, hosted by IseeQ and sponsored by think-cell. This session brings together speakers from think-cell, Spotify, and Zühlke Engineering for an evening focused on three essentials of modern C++: performance, security, and type safety.

Tuesday, October 21, 2025 – 17:30
at Create26, Király utca 26, 1061 Budapest

Jonathan Müller (think-cell) – Cache-Friendly C++
Performance starts at the hardware level. Jonathan will explain what “cache-friendly” really means, how CPU caches work, and how to structure C++ code and data for optimal cache use.

Dargó Sándor (Spotify) – Strongly Typed Containers
Type safety at scale: Sándor will explore how to design strongly typed containers, when to bend STL conventions, and how to use composition and open-source tools to write clearer, safer C++ code.

Juhász Marcell (Zühlke Engineering) – Hacking and Securing C++
Marcell will demonstrate how classic C++ vulnerabilities arise in embedded systems, how exploits actually work, and how modern C++ techniques such as RAII, smart pointers, and bounded containers help prevent them.

This meetup is a hands-on look at how C++ is built, broken, and rebuilt — from low-level memory details to high-level design principles.
