Let's start with a php5.3+ grammar sugar, which we usually write about:
Syntax sugar can be written like this:
Execution results $b = 1, the latter is more concise, but usually not too much syntax sugar, especially easy to understand confusion, such as the new increase in PHP 7?? As follows:
Equivalent:
?: and?? You are not easy to confuse, if so, I suggest rather not, code readable, easy to maintain more important.
Grammar sugar is not the focus of this article, we aim to talk about the

The specific method is to modify the NIC configuration file under the/etc/sysconfig/network-scripts directory, such as binding etho, then modify the ifcfg-eth0 and ifcfg-virbr0
The modified configuration file is as follows:
1) ifcfg-eth0

After the memory is allocated to the virtual machine, the Hyper-V host allocates the available memory resources of the system to the created virtual machine. The default memory is called static memory, that is, when you create a virtual machine, how much GB of memory is allocated to the virtual machine. The dynamic memory function provided by Windows Server 2012 Hyper-V allows the Administrator to re-adjust resources, make full use of limited memory resources to achieve better memory integration

VMware workstation/fusion are the corresponding desktop virtualization software under Windows/linux and MacOS respectively. In the past, after installing an operating system virtual machine in VMware, it was necessary to install the VMware Tools Enhancement tool in the virtual machine to enable file sharing between host and virtual machines, virtual machine display resolution adaptive tuning, virtual machine display capability enhancement and 3D acceleration.

The two modules to be introduced today are assert and VM. Next we will introduce them separately.
Use assert for testing
Node, we can use the assert module to test the code. Equal () and notequal () are used to determine equality and inequality respectively. The first parameter is the expected value, the second parameter is the real value, and the third parameter is the exception information. The example is as follows:
var assert = require('assert')
