Random repetitive problems in a short time

First of all, I saw the solution in that article:

Method In fact no difference is just code because of the big God Hand, resulting in code size is not clear, new people see also have to change a lot, just like me! So write the code again. One is for the convenience of everyone is also for fear of forgetting, after all, not used/

The focus is on the GUID: the globally unique identifier (guid,globally unique Identifier) is a numeric identifier generated by the algorithm with a binary length of 128 bits. GUIDs are primarily used in networks or systems that have multiple nodes, multiple computers. Ideally, no computer or computer cluster will generate two identical GUIDs. The total number of GUIDs reaches 2^128 (3.4x10^38), so the probability of randomly generating two identical GUIDs is very small, but not 0. The term GUID also sometimes refers to Microsoft's implementation of the UUID standard.

Ideally, no computer or computer cluster will generate two identical GUIDs. The probability of randomly generating two identical GUIDs is very small, but not 0. Therefore, the algorithm used to generate the GUID usually adds non-random parameters (such as time) to ensure that this repetition does not occur.
