C++26 pack indexing lets you select types and values from parameter packs directly with pack…[I], which removes a lot of tuple and index_sequence ceremony from metaprogramming utilities.

Techniques for type dispatch in C++: tag dispatch, if constexpr, std::variant with std::visit, and how to choose the right approach for your use case.

Practical techniques to resolve C/C++ macro name collisions between system headers and user code: undef, parenthesization, and inline function workarounds.

A deep dive into a subtle C++ performance bug: why over-aligned dynamic memory allocation was undefined before C++17 and how alignas interacts with operator new.

Deep dive into NanoLog, an extremely fast C++ logging library: how it achieves nanosecond-scale latency with lock-free queues and cache-line alignment.

Source code analysis of Google’s glog logging library: how it handles log severity, log file rotation, signal handling, and thread safety.

A guide to returning values effectively in C++: RVO, NRVO, move semantics, and when to use out parameters — with benchmarks and compiler guarantees.
