Underlying Principles of Docker

The core problem that Docker solves is application packaging. Containers themselves have no value; the value lies in container orchestration. Underlying Principles of Docker The underlying principles of Docker utilize Linux’s Cgroups and Namespace technologies. Cgroups are the primary means of creating constraints, while Namespace technology is the main method for modifying process views (isolation). … Read more

Detailed Explanation of Namespaces in C++

Namespaces in C++ are used to organize an excessive number of classes for easier handling of applications. To access classes within a namespace, we need to use namespacename::classname. We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more

Understanding C++ Namespaces: Definition, Use, and Scope Resolution

Understanding C++ Namespaces: Definition, Use, and Scope Resolution In C++ programming, namespaces are an important feature used to resolve identifier conflicts. As the scale of the program increases, the number of functions, classes, and variables in the code also grows, which may lead to naming conflicts. To address this issue, C++ introduced the concept of … Read more
