Swift gets Current timestamp (sec, millisecond) It is often seen that a second-level timestamp is obtained in the form of an Int type direct * 1000来 MS, so that the final 3 digits are 0, and the results are not accurate enough. So there's another way to get a millisecond timestamp. Create a Date Extension with the following code Extension Date { ///gets the current second-level timestamp-10-bit var timestamp:string {let timeinte

Someone asked me how to use webshells today. It looks quite simple, but some people may not know it, so I wrote it wrong. I hope you can correct it. Instructions for use: Webbench-C 5-T 120 http ://ABCD. Com/index. php -C indicates the number of concurrent clients to be simulated, and-T indicates the concurrency time. The HTTP prefix must be added. Otherwise, the test fails. If the domain name is used, the domain name must have the last slash. For example, webbench-C 5-T 120 http ://A

determine the internal transmission rate of hard disk, to a large extent directly affect the speed of the hard disk. The faster the speed of the hard disk, the faster the hard drive to find files, the relative speed of the drive is also improved. The speed of the hard disk is expressed as the number of revolutions per minute, the unit is expressed as RPM,RPM is revolutionsperminute abbreviation, is the RPM. The larger the RPM value, the faster the internal transfer rate, the shorter the access
