Adding std::mutex does not automatically make C++ code thread-safe. This article breaks down three practical rules for using std::mutex safely: rely on RAII, keep synchronization boundaries explicit, and treat std::recursive_mutex as a design smell before treating it as a solution.

Transactional memory looks like an elegant solution to concurrency problems — but in C++, it comes with serious trade-offs.

This article walks through GCC’s transactional memory implementation, explains how atomicity and rollback work in practice, and compares performance against mutex-based solutions. You’ll learn when transactional memory simplifies concurrent code — and when it makes things worse.

When reads dominate writes, a mutex can turn into a scalability bottleneck. This article explains a simple copy-on-write “snapshot” pattern for C++20 using std::atomic: lock-free reads in user code, safe atomic updates for writers, and the trade-offs that decide when this approach is worth it.

Mutexes protect data. Actor-like queues protect behavior. Here’s why the second approach often makes correctness easier—and when it’s the wrong choice.
