虽然从来没打过网球，也没看过完整的网球比赛，但是我觉得网球这项运动区别于其它运动最特别的一点是：一旦运动员上场比赛，中间就不能再获得教练的帮助，要自己独自面对场上发生的一切情况。所以李娜的自传书名是《独自上场》。
实际上，不止于网球，很多事情上我们都是“孤独”的，需要随时做好“独自上场”的准备。“独自上场”，才是生活的常态。
前几年听过张潇雨的播客《网球（上）——孤独和它所创造的》，专门介绍网球这项运动，这次奥运会想起来这期节目，只可惜好像这期节目没有下半段了。
这期播客里提到的《The Inner Game of Tennis》（中文《身心合一的奇迹力量》），多抓鱼上一直买不到。

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.
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
