Software Engineering Is About Tradeoffs - Mateusz Pusz - CppCon 2021

---

This talk presents a view of a Software Architect on designing interfaces. Often there is no such thing as "the best" solution for the problem. In many cases, we have to deal with compromises and accept the downsides of a specific approach. We often have to choose between exception safety guarantees, performance, dynamic allocations, and standardization or implementation effort.

During the talk, I will present some of the major trade offs and disagreements regarding the C++ design. I will also describe a few issues I encountered during the design of mp-units (the modern C++ physical units library) and ask the audience to make a choice between several alternative solutions to the problem.
