#数据库
在中国做数据库的，多少都听过 萨师煊 教授的名字，他撰写的《数据库系统概论》第一版于1983年出版，是中国大陆第一本讲解数据库系统实现的专著，人民大学在数据库领域也是内地最强的几所高校之一。
今天看到《萨师煊教授：国产数据库学科的拓荒人与奠基者》一文中提及他的家世，才知道这么显赫：
* 萨氏源于山西雁门萨氏先祖，已有六七百年的历史，祖先是蒙古色目人。
* 最早的先祖是元代四大诗人之一的萨都剌，曾官至南台侍御史，钦赐萨姓，此为萨氏家族立姓之始。
* 萨都剌的孙子萨仲礼是元统年间（1333年）的进士，官至福建行中书省检校，举家由晋迁闽，子孙繁衍渐成望族。
* 后人中包括：爱国海军将领 萨镇冰、中山舰长 萨师俊，物理学家 萨本栋、化学家 萨本铁、微电子学家 萨支唐、数学家 萨支汉等等。

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
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.
