#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。

The S&P 500 slumped 1.8% on Monday and Tuesday, thanks to China Evergrande, the Chinese property company that looks like it is ready to default on its more-than $300 billion in debt. Cries of the next Lehman Brothers—or maybe the next Silverado?—echoed through the canyons of Wall Street as investors prepared for the worst.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
