So you got yourself access to a Debian server (or virtual private server) and have logged into it by one way or the other. In this tutorial, we will learn how to set up such a bare-bones server so you can access it remotely via...
A generic factory is a factory that can register any class type. It is very easy to write because we are allowed to use void pointers.
void Register(const std::string _key, const std::function<void *()> _creator)
m_creators[_key] = _creator;
ClassType* Get(const std::string _key) const
return static_cast<ClassType *>(m_creators.at(_key)());
std::map<std::string, std::function<void *()> > m_creators;
Derived1 *d1 = f.Get<Derived1>("Derived1");
Derived2 *d2 = f.Get<Derived2>("Derived2");
Derived1 *d2 = f.Get<Derived1>("Derived2"); // This also compiles!!!
As we are simply casting a void pointer, it is left to the developer to ensure...
Problem statement: Find the largest sum that is possible in an array. I.e., find the maximum sub-array. Solution: From the very first this problem looks complicated because of how it is framed. It sounds like we want to find the MAXIMUM from ALL THE POSSIBLE...

‘C++ Traits’ is an idiom that allows a great level of abstraction at compile time which is normally possible only by a combination of inheritance and composition. It allows an algorithm to change its behavior depending on the object’s traits, i.e., functions and member variables...
In my previous post, I gave the rather simple steps to install MSYS2/Mingw-w64. Now I will tell you how to install a custom library, specifically log4cxx. Before starting, lets acknowledge that there are other libraries that might fit your logging needs. The installation steps will...
