What happened
Anton Zhiyanov published 'Go Concurrency Distilled,' a free interactive mini-book and PDF covering goroutines, channels, select, pipelines, context, wait groups, data races, mutexes, semaphores, atomics, testing, scheduling, and diagnostics. It is explicitly 'AI-free' and positioned as a quick refresher rather than a beginner's guide. The Hacker News thread has 234 points and 94 comments.
Why it matters
If you write Go, the interactive examples let you test concrete behaviors like channel sends blocking until a receive and the WaitGroup.Go pattern that removes manual Add/Done bookkeeping before you change production concurrency code. It is a low-cost refresher for reviewing goroutine leaks, race conditions, or context cancellation; non-Go builders can skip it.
Discussion angle
Where does your team still use manual wg.Add/Done instead of WaitGroup.Go, and which concurrency bug class—data races, leaked goroutines, or context cancellation—costs you the most time?
