Gist of Go: Concurrency is out!

My book on concurrent programming in Go is finally finished. It walks you through goroutines, channels, select, pipelines, synchronization, race prevention, time handling, signaling, atomicity, testing, and concurrency internals.

The book follows my usual style: clear explanations with interactive examples, plus auto-tested exercises so you can practice as you go. I genuinely think it's the best practical guide for everyone learning concurrency from scratch or looking to go beyond the basics.
