我特别喜欢在技术文章中画图，有两个原因：对作者而言，如果能用图表达思路，侧面说明是真的掌握了；对读者而言，图形也比一维的文字更容易理解、信息量更大，图形中可以增加联系、颜色、形状等多维度信息。
所以一方面要让自己真的掌握一个知识点，另一方面要锻炼自己的画图表达的能力，以画图来反向验证自己对知识的掌握。画图的一些心得，参考我以前写的文章：《技术配图的一些心得》。
至于我用的画图工具，现在如果是随手画的图，就用excalidraw；一些更为正式的图，就用Mac上的OmniGraffle，可以很方便得对齐、调整颜色、字号大小等等，大几百买断的单机单平台软件，但是超值。

Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
