#纪录片
《何以中国》（B站，宣传片），偏考古向的纪录片，讲述史前到秦代文明的历史，追溯中华文明的根基、发源与早期形成和发展。由于这段历史很多部分是没有文字记载的，所以辅之以相应的考古发现，加上拟人化的场景还原。文本台词、摄影都很棒，制作很精美的历史纪录片，我感觉不输以前看过的《河西走廊》。
另外，夏朝的部分一笔带过，看来目前为止的考古发现还没有找到夏朝真实存在过的强有力证据。

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.
Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
