Matlab 是因为有别的软件依赖它编译没办法
Mathematica 主要是那个“可计算数据”的数据库非常完整而且收录速度非常快，同时 Wolfram Alpha 的多步调用很方便，再配合它方便的语法才成为了我的首选（而且还有官方中文的帮助文档）
GNU Octave 只能说…… 他能用，但语法上用起来不够爽，更不要说没有结构化的数据库了

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
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.
