Missing (and future?) C++ range concepts
Iterators and ranges have been essential parts of the C++ standard library since its inception. With C++20, they were brought to the next level in the form of std::ranges: We now have formalized requirements on the algorithms, lazy views to enable pipelines, and much more powerful iterators ...

C++ Performance Tips: Cutting Down on Unnecessary Objects
In C++, unnecessary temporary object creation can lead to costly runtime operations, increased code execution, and higher memory usage. Luckily this can be improved. This talk investigates common scenarios that result in the creation of temporary objects, demonstrated through code examples ...

Better Threading support in C++20
We got threading support by the language and library in C++11. There were however a few things missing, like RAII for a thread object, or a nice way to stop a thread, or to request it to stop. Similar problem, how do we stop a ‘waiting’ condition variable ...

An introduction to reinforcement learning: Snake your way out of a paper bag
When people talk about AI they tend to mean LLMs, so this talk will to remind us of other approaches to AI. Reinforcement learning (RL) is a type of machine learning, so part of AI. An 'agent' takes actions in a dynamic environment. Better outcomes are rewarded and worse outcomes are penalised ...

Welcome to v1.0 of the meta::[[verse]]!
This talk will introduce what is (likely) the final version of the 'Reflection' feature targeting C++26. With a proposal slated to introduce reflection to C++26 (including the “std::meta” namespace) getting strong support in WG21, we can already start imagining a whole new world of possibilities ...

C++ Value Categories in Action: The Foundation Behind Overloads, Moves, and the Broader System
Lvalues, rvalues, xvalues, glvalues, prvalues, reference binding, std::move, and temporary materialization - we have heard of them, we use them regularly, and they are part of every C++ programmer’s daily work, but if I am honest, my own grasp of how they truly interact was a bit rusty until I dug i ...
