1. Concurrency Programming (4): How Mutexes Are Implemented — From Runtime to CPU

    Traces the actual implementation paths of Java synchronized, Go sync.Mutex, and CPython threading.Lock to show how mutexes rely on atomic operations, memory ordering, and waiting and wake-up mechanisms.

  2. Concurrency Programming (3): Mutexes — Atomicity, Visibility, and Ordering at the Language Level

    Continues with counter++ to explain how mutexes provide atomicity, visibility, and ordering, then compares Java synchronized, Go sync.Mutex, and CPython threading.Lock.
