Today, when using VMware to install new virtual machines in a machine, "This host supports Intel Vt-x, but the Intel Vt-x is disabled" error is as follows:Prompt information:The virtual machine has been configured to use a 64-bit client operating system. However, 64-bit operations cannot be performed.This host supports Intel Vt-x, but Intel Vt-

Recently always encountered some annoying things, such as using Python3.5 to write some code, some do not understand the place, go online to find the answer, but found that many are based on python2.x. Today I'm going to come up with some problems. Unicode stringIn Python2, normal strings are stored in 8-bit ASCII, while Unicode strings are stored as 16-bit Unicode strings, which can represent more character sets. The syntax used is to precede the

Use Teensy to simulate the e-mapreduce x card and crack the feasibility of the e-mapreduce X-class access control system. The previous day, Open started Teensy ++ 2.0. Therefore, we studied Teensy ++ 2.0 simulation eminix and conducted a brute-force cracking test on the access control of eminix, the following is the relevant code and content.What is low frequency?

version number of spring--also need to understand this very not intuitive fact, spring Security 3.1.x also does not rely on the spring 3.1.x version number ! This is because spring Security 3.1.x was announced prior to spring 3.1. Spring plans to keep these dependencies as consistent as possible in a future version number, and want to know a lot of other informa

Take the remainder function PHP to take the remainder function PHP two to take the remainder MOD (x, y) x%y MOD For example: 9/3,9 is the divisor, 3 is the divisor. The MoD function is a redundancy function in the form of:MoD (NEXP1,NEXP2), which is the remainder of two numeric expressions after the division operation. So: The two integers are the same as you know two positive balance (that is, two negativ

Texture Optimization in Cocos2d-x optimization, cocos2d-x optimization texture1. Texture pixel formatAnother important indicator of texture optimization is the texture pixel format. To maximize the user's fidelity requirements, select the appropriate pixel format, this greatly improves the processing speed of textures. In addition, the texture pixel format is closely related to hardware.Next, let's take a l

Update and insert locks There are two types of locks involved, one is the range S-U lock and the other is the range X-X lock. Range S-U, which gets the S lock for the selected index range and the key hit is locked using the U Lock for future conversion to the X lock. When the update
