A guide to std::thread, preventing data races with std::mutex, and task-level parallelism with std::async.

Why C++17's algebraic data types replace output-parameter hacks and null pointer returns for safer APIs.

Best practices for writing robust classes: copy/move constructors, assignment operators, and destructors.

When to use constexpr over const and how compile-time evaluation can drastically reduce runtime overhead.

How std::move works under the hood and why rvalue references are crucial for zero-cost abstractions in C++11 and beyond.

How C++20 Concepts constrain template arguments, drastically improving error messages and API clarity.

Capturing variables by value vs reference, mutable lambdas, and using them with STL algorithms.

Type deduction in Modern C++: how auto, auto&, and auto&& differ, and best practices to balance readability vs terseness.
