Read more →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…
Read more →Consider a simple counter increment: counter++. This single line compiles to at least three CPU operations—load, add, store. Between any of these steps, another thread can intervene, leading to…
