My motto for all programming activities is: write unique code. A mindset and philosophy I transfer in my classes as well.
Furthermore, I'm the creator of C++ Insights: See your source code with the eyes of a compiler. In case you haven't already heard of C++ Insights, it is a Clang-based tool that shows how the compiler sees your source code. C++ Insights transforms your C++ input into an enriched version with all the things your compiler adds to the source code behind the scenes. C++ Insights assists me in my training classes to explain certain aspects of C++. My classes are, in general, highly interactive with a lot of examples.
