#TIL 高速上那种黄黑相间的护栏开始部分的标识（Impact head）其实是可以帮助减小碰撞冲击力的装置，撞上去会把后面的钢铁护栏弯折形变的。甚至水泥护栏头也有一段是吸收 impact 的。
我之前一直以为撞上这个东西就死神来了呢……基建工程师们为了我们在路上能活着真是煞费苦心啊！

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.
The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
