深入Go并发编程研讨课

Go提供了我们便利的进行并发编程的工具、方法和同步原语，同时也提供给我们诸多的犯错的机会，也就是俗称的“坑”。即使是顶级Go开发的项目，比如Docker、Kubernetes、gRPC、etcd， 都是有经验丰富的Go开发专家锁开发，也踩过不少的并发的坑，而且依然源源不断的继续踩着,即便是标准库也是这样。

分析和总结并发编程中的陷阱，避免重复踩在别人的坑中，正式本次培训课的重要内容。只有深入了解并发原语的实现，全面了解它们的特性和限制场景，注意它们的局限和容易踩的坑，才能提高我们的并发编程的能力。通过了解和学习其他人的经验和贡献的项目和库，我们可以更好的扩展我们的视野，避免重复的造轮子，或者说我们可以制作更好的轮子。

语言的内存模型定义了对变量的读写的可见性，可以清晰而准确读写事件的happen before关系。对于我们，可以很好地分析和编排goroutine的运行，避免数据的竞争和不一致的问题。

[V=browser-hello.mp4] Hi, I'm Matthew from OpenResty Inc. In this video, I'll demonstrate how to implement a "hello world" HTTP interface using OpenResty.

First of all, we make sure we are using OpenResty's nginx.

    [delay=0] $ export PATH=/usr/local/openresty/nginx/sbin:$PATH
    $ which nginx

[S] It's usually in this path.

And then we go to the home directory.
