Finally found time to write small article about RAII idiom and unique_ptr. It can be found there
The writing of such article was prompted by the fact that many people who come to an interview do not know the basics of C++ and basic constructs at all, the use and understanding of which is simply necessary.
Yes, of course, many things is not as such important as others, for example, how the operating system works and often this knowledge is not so absolutely needed from my experience.
But the case of smart pointers in C++ is completely different. It is how to be able to breathe.
Later I plan to extend it with information about other pointers as well.
