最早的时候，谷歌搜索的网址是挂在斯坦福大学的网站上的。谷歌的创始人拉里·佩奇和谢尔盖·布林在1997年发表的论文中说：
“我们认为由广告商来赞助搜索引擎，将会使得搜索引擎的返回结果受到广告商的需求的影响，从而偏离真正的用户需求。广告越多，搜索引擎的搜索质量就越差。正因为广告商的存在会极大影响搜索引擎的质量，我们相信我们的社会需要一个搜索质量优秀、排序公正透明、由学术界监督的搜索引擎。” source

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
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.
