This section contains various reminders to jog your memory if you’re not too fresh on basic Erlang data, types, or syntax. gen_server模块提供了该函数的默认实现，它记录了意外的Info消息，并将其丢弃并返回{noreply，State}。当发生超时或接收到任何其他消息时，由gen_server进程调用此函数同步或异步请求（或系统消息）.Info可能是原子超时，发生超时或接收到的消息。 gen_server is a component of OTP, the Open Telecom Platform.

{i_am_at, Person, Location} is a command which is passed to the server, and 10000 is a timeout value. A gen_server is a specific finite state machine working like a server. gen_server can handle different type of event: synchronous request with handle_call.

Writing gen_servers has become a routine. We have dozens of gen_servers in our applications, but when we get to a point of extending the server behaviour, we start scratching our heads. gen_server在erlang otp编程中的地位是无可撼动的，几乎都是gen_server或者gen_fsm的模型。那么程序运行起来的时候 我们如何查看gen_server的内部状态呢。有2种方法： 1. 自己写个类似于info这样的函数，来获取状态。 2. 利用系统现有的架构。 If you do not intend to replace the Erlang distribution protocol, or replace the gen_server protocol, skip over this chapter.
