很多人在扯文科有用无用。昨晚我忽然想到一个关于有用的递归定义：
1 所有直接关系人类生存的物质都是有用的。
2 所有能促进有用物质生成的，都是有用的。
可以通过这个递归关系递归几次能到1，算一个「有用距离」。

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.
At a time when the Indian stock market is peaking and has rallied immensely compared to global markets, there are companies that have not performed in the last 10 years.
