Using smart pointers for class members
...ving trouble understanding the usage of smart pointers as class members in C++11. I have read a lot about smart pointers and I think I do understand how unique_ptr and shared_ptr / weak_ptr work in general. What I don't understand is the real usage. It seems like everybody recommends using uniq...
What are good examples of genetic algorithms/genetic programming solutions? [closed]
...everything in their power to hurt the competition.
Edit:
I wrote it in C++ using no frameworks. Wrote my own neural net and GA code. Eric, thank you for saying it is plausible. People usually don't believe in the powers of GA (although the limitations are obvious) until they played with it. GA i...

Lock, mutex, semaphore… what's the difference?

Here's a quick tour noting how some languages answer these details.
C, C++ (pthreads)
A mutex is implemented via pthread_mutex_t. By default, they can't be shared with any other processes (PTHREAD_PROCESS_PRIVATE), however mutex's have an attribute called pshared. When set, so the mutex is sha...

What does “abstract over” mean?
...al quick and the language doesn't directly support it). If you wrote it in C++ you could use oop concepts to reduce the complexity of the problem(well, it's the same complexity but the conceptualization is generally easier(at least once you learn to think in terms of abstractions)).

Why does calling a method in my derived class call the base class method?
...
Subtype polymorphism in C# uses explicit virtuality, similar to C++ but unlike Java. This means that you explicitly have to mark methods as overridable (i.e. virtual). In C# you also have to explicitly mark overriding methods as overriding (i.e. override) to prevent typos.
