Go Concurrency Patterns

A solid collection of battle-tested Go concurrency patterns that covers the essentials: worker pools, fan-out/fan-in pipelines, semaphore-based rate limiting, and graceful shutdown handling. The code examples are production-ready and demonstrate proper context usage, channel management, and synchronization primitives. What I appreciate is the focus on real patterns you'll actually encounter, like bounded concurrency and proper goroutine lifecycle management. The graceful shutdown pattern alone is worth having on hand since most tutorials skip this crucial piece. Perfect reference when you need to implement concurrent processing or debug those inevitable race conditions that pop up in Go services.
