Article Title: Obtain the CPUID, hard disk serial number, and MAC address in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In the development of many system software, some system uniqueness information is required. Therefore, obtaining the host's CPUID, hard

fingerprint encryption is the acquisition of computer hardware information. We need to read the machine identification one by one through a program and use certain algorithms to restrict user authorization based on the machine identification. Common hardware resource package: Hard Disk Physical serial number, CPU serial number, Nic MAC address, BIOS serial number, and motherboard serial number. If your har

If you want to install a pure version of the MacOS Sierra operating system, consider creating a USB installation disk. Today, we'll talk about the specific approach, which applies to MacOS Sierra's beta, public beta and final official editions. First, we need to prepare at least 8GB USB drive and make sure that there is nothing in it that you want to keep, as the following tutorial will erase all the data on the USB drive. 1. Download t

Recently hit patch, because the server C disk space is not much of the results generated a lot of alarm, although not very serious but this problem can be avoided, wrote a very simple script to detect the server C disk space, and you shareFirst you need to gather information about the server, primarily the FQDN, and th

This paper introduces in detail the method of using C # to calculate the disk space occupied by this path according to the path.There is a lot of information on the Internet to get the size of the folder/file. There is very little complete code for the space footprint. The complete code for this function is described h
