Go Tutorial Series Launches with In-Process Concurrency and CSP Pipeline Basics

A new hands-on tutorial series titled 'Go Distributed Systems Lab' has launched on DEV Community, targeting developers building distributed systems using Go 1.22 and its standard library. The first module focuses on foundational concurrency concepts — goroutines, channels, and Communicating Sequential Processes (CSP) — before progressing to advanced topics like gossip protocols and Raft consensus across 20 planned projects. The guide contrasts Go's channel-based communication model with traditional mutex-heavy approaches used in languages like C++ and Java, highlighting how Go eliminates data races by design. A working three-stage data pipeline — comprising a producer, a worker, and a collector — is constructed using only standard library packages including sync, context, and log/slog. The implementation demonstrates how each pipeline stage operates on isolated memory, passing ownership through typed, direction-constrained buffered channels rather than shared state.
