Traditional mutex-based concurrency works well until it doesn’t. Under high contention, threads spend more time waiting for locks than doing actual work. Lock-free programming sidesteps this by using…

Atomic operations are indivisible read-modify-write operations that execute without interference from other threads. Unlike mutexes that use operating system primitives to block threads, atomics use…

Traditional mutex-based synchronization works well until it doesn’t. Deadlocks emerge when multiple threads acquire locks in different orders. Priority inversion occurs when a high-priority thread…

Concurrent programming in Go typically involves protecting shared data with mutexes. While effective, mutexes introduce overhead: goroutines block waiting for locks, the scheduler gets involved, and…

Compare-and-swap is an atomic CPU instruction that performs three operations as a single, indivisible unit: read a memory location, compare it against an expected value, and write a new value only if…

Multi-Producer Multi-Consumer (MPMC) queues are fundamental building blocks in concurrent systems. Thread pools use them to distribute work. Event systems route messages through them. Logging…
