Advanced Go Concurrency Patterns

A simple (mock) RSS subscription fetcher for practicing go concurrency patterns:

• Use for-select loop to write more responsive code
• Use nil channels to disable select cases
• Use chan chan error to avoid data race that usually happen in Close()

The directory practice contains the necessary boilerplate code for you to practice on your own.

To give it a run: cd improved; go run main.go

To practice on your own:

1. cd practice
2. vim main.go
3. go run main.go: go to 2 if anything goes wrong
