周末读《TCP/IP 详解》，学到一个非常神奇的协议：RFC 865 - Quote of the Day (QOTD)
One quote of the day service is defined as a connection based application on TCP. A server listens for TCP connections on TCP port 17. Once a connection is established a short message is sent out the connection (and any data received is thrown away).
简而言之，通过端口 17 交互每日 " 名人名言 "。
受教主的启发，将该协议用于 github profile 的更新。
核心代码如下，配合 github action 每日定时执行：https://github.com/daya0576/daya0576
BTW, this post & profile repo are both created by vim :p
