  Only 4G can resolve the conflicts between China Telecom Carriers and WeChat ?

Why WeChat has made the three big Chinese telecom companies uncomfortable? Let's analyze from both technical and commercial levels.

Instead of using technical terms, we will explain in simple vivid phrases. First, mobile QQ, or WeChat, will have their own "request frequency". These requests are sent to the carrier network, to check the re...

This question is very common and there are many solutions, here we introduce a straightforward method. In Linux, each file will be stored on one device and of course there will be a relative inode, then we can use vfs.write to know who is writing the inode on one specified device continuously. Luckily there is inodewatch.stp in the installation package of s...
