#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。

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
