I set it casually here, nothing special.Next, to get the context of WEBGL, you need to use the GetContext function, the GetContext function is to get the context object from the canvas, the argument is a string, specify the name of the context you want to get.When this article was written (February 2012), the context of WEBGL is not yet available through the official name WebGL, and the context obje

Python is an object-oriented development language, the use of global variables in functions, generally should be described as global variables, only in the function of the described global variables can be used, the following describes the Python global variables related issues. You should try to avoid using Python global variables. Different modules are free to access global variables, which can lead to the unpredictability of global variables. For global variables, if programmer a modifies the

Client-server mode, the command issued by the client does not require an immediate response from the server, if the client and the server in a network, one command will appear inefficient, so the command will be cached in the client and then sent together, so the client needs a mechanism to confirm that the server has completed the execution of the command, Given that OpenGL ES is multithreaded, the execution of thread A is important to synchronize the execution of individual threads, such as th

Nic parameter configuration in Linux In Linux, there are many methods to modify the NIC parameters. The first method is to modify the/etc/network/interfaces file. This method can still be effective after restart; another method is to use the ifconfig command. This method can only temporarily modify Nic parameters and will expire after restart.First: Modify the interfaces File The interfaces file is in the/etc/network/folder. It is a network interface configuration file that contains the configur

Because these two pieces of data are logically integrated, we need to point each other through pointers to form a one-to-one relationship. 2.Bind the address on the inet BSD socket To listen to incoming Internet connection requests, each server needs to establish an
