This mini diary app showcase my current skill with File I/O. There is no data storage in this first edition. This version of the App is limited. Every new entry to the app overwrite (deletes) the previous entries. To make it short, this app has a primitive technology characteristic.

一个基于 Go 实现的环形（Ring）Writer，核心特性是当写入数据的总容量超过预设字节限制后，新写入的数据会从头覆盖旧数据。适用于循环存储有限容量日志、临时数据等场景。
