ubuntu 是来源于非洲的一整套哲学价值体系，这套价值体系的核心在于人和人之间的联系 —— 有你才有我。ubuntu 这个词的直译是“善待别人”。
而 Ubuntu 操作系统的团队选取这个名字，是因为这个团队希望将 ubuntu 的精神带到电脑和软件的赛博世界里。
注：Ubuntu 是一款基于 Linux 的操作系统。Ubuntu 的读音是，“乌邦兔”。 source

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
