20:45-21:00 Closing

Abstracts for the talks:

Writing C++ code that translates to fast machine code
One of the key strengths of C++ is that it produces fast program executables, so if you want your programs to be fast, C++ is a natural choice. But, does all C++ code produce optimal machine code?

In this talk we will highlight a few things to consider when aiming for optimal execution performance, ranging from the importance of how to structure your code, to knowing your target CPU architecture and compiler strengths, quirks and limitations.

Which function are you calling? Argument-dependent lookup in C++
Argument-dependent lookup allows using functions and operators without using fully qualified names. It is an important feature but it can lead to non-intended behavior as the compiler might look for functions in places you did not initially expect. In this talk we will show a few examples of when ADL caused issues and non-intended behavior.
