What is Bandwidth
云服务器带宽和流量的区别云服务器的带宽配置主要分为两种描述方式：带宽上限 和 流量上限。以下是它们的详细介绍和对比。 1. 带宽上限（如 4Mbps）含义带宽表示服务器与网络连接的速率上限，单位通常为 Mbps 或 Gbps。 示例：4Mbps 表示每秒最多传输 4 兆位数据，实际速率约为 0.5 MB/s。 适用场景限制峰值流量：控制服务器的峰值速率，适合需要稳定网络连接的场景。 持续传输数据：如 HTTP 服务、流媒体等需要长时间稳定传输的应用。 常见原因固定速率分配：云厂商为入门级套餐设定的固定带宽。 按峰值带宽收费：更便于用户管理成本。 计算预估流量假设每天持续使用 4Mbps 带宽，可计算月流量： 1月流量 = 4 Mbps × 3600 秒/小时 × 24 小时/天 × 30 天 ÷ 8 结果约为 1.3TB/月。 2. 流量上限（如 2TB）含义流量上限是指每月可传输的数据总量（上传+下载），但不限制速率。 适用场景弹性使用：突发性流量需求高，例如大文件下载、CDN...
Run the command in the background
IntroductionSometimes, you really need those server-wide program to run in background, because you need to avoid some accidents to interrupt our service program. There are some methods I will introduce here: 1. tmux: tmux new -s [tty-name]: start a new tty window with your set name tmux attach -t [tty-name]: attach a existing tmux tty with name crtl + b and then d: exit tmux tty but keep it in background LATER but this command or we call it shortcut sometimes don’t work, if I find the...

Why do you think the English Tenses is so confused?
时间&状态未分清学校教授时态时，往往是将时间和状态混合在一起教，导致学生对时态仅有一个模糊的整体概念。或者即使区分，也并不特别指出。这就导致很多人脑种的时态概念是这样的： 这解释了为什么在学校学到的英语会强行加入很多语法规则，什么时候必须用一般将来，什么时候用过去将来完成时等等。规则复杂没有统一的规律绝对是大多数人在学习英语时被劝退的头号通缉犯。但是如果你问Native English Speakers，他们会说根本不知道什么是时态，就是怎么自然怎么说。 因此，我们需要知道时间和状态其实是两个概念，而完整的时态是由时间和状态排列组合而成的。 动词变位（Verb Conjugation）单词拼写往往会改变。 在中文里表达时间概念时，只需要加上对应的时间相关的描述词即可，不需要对字本省做出任何改动，比如： 我已经吃过饭了 我正在跑步 但是在英文中，我们不仅需要加上对应的时间相关的描述词，还需要对动词本身的拼写做出改变， 比如： I ate an apple. （时态变位） She eats an apple. （人称变位） I have eaten an apple....
