#开源项目
这段时间都在做自己的开源项目replited，用于备份sqlite数据库文件，项目参考了litestream如何利用sqlite的WAL机制做到增量备份，由于使用了opendal，这样接入各类型的存储后端会更方便一些。
这是我打算在sqlite生态上做一点事情之后，交出的第一个项目，我也想看看最后自己能做到什么程度。

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
