Copy Semantics of std::vector::push_back and Alternative Approaches
This paper examines the object copying behavior of std::vector::push_back in the C++ Standard Library. By analyzing the underlying implementation, it confirms that push_back creates a copy of the argument for storage in the vector. The discussion extends to avoiding unnecessary copies through pointer containers, move semantics (C++11 and later), and the emplace_back method, while covering the use of smart pointers (e.g., std::unique_ptr and std::shared_ptr) for managing dynamic object lifetimes. These techniques help optimize performance and ensure resource safety, particularly with large or non-copyable objects.

Extending External Types in Go: Type Definitions vs. Struct Embedding
This article explores techniques for adding new methods to existing types from external packages in Go. Since Go doesn't allow direct method definition on foreign types, we examine two primary approaches: type definitions and struct embedding. Type definitions create aliases that access fields but don't inherit methods, while struct embedding enables full inheritance through composition but requires careful pointer initialization. Through detailed code examples, we compare the trade-offs and provide guidance for selecting the appropriate approach based on specific requirements.
