Concurrency made easy - GopherCon SG 2017

Dave Cheney 的演讲总结：

• If you have to wait for the result of an operation, it’s easier to do it yourself.
• Release locks and semaphores in the reverse order you acquired them.
• Channels aren’t resources like files or sockets, you don’t need to close them to free them.
• Acquire semaphores when you’re ready to use them.
• Avoid mixing anonymous functions and goroutines. – loopclosure
• Before you start a goroutine, always know when, and how, it will stop.
