With the mobile network upgrade: 2G->3G->4G even the development of 5G, the network speed is more and more fast, but this flow is like flowing water generally rushing away.Online is not a joke: sleep forgot to close the flow, the next day the house will be moved!This is an exaggeration to say, but as a good app developer, we need to give the most appropriate hints in the app.Give some hints when you need to
In the Linux world, the use of SYSTEMD has been the subject of intense debate, and the fighting between its supporters and opponents is still burning. Today, most mainstream Linux distributions have adopted SYSTEMD as the default initialization init system.
As the authors say, as a "never finished, the system, which has never been perfected, but has followed technological progress, is not just an initialization process, it is designed as a broader system and service management platform, a SYSTE
A loop problem occurs in the use of wireless networks. Where is the problem? Who is the culprit? The author of this article gives you a detailed description of how to set up your own experience.
Unit A subnet has been working normally, but I found that workstations in subnet A recently cannot access the LAN server. After some careful checks, I can see that the new switch devices in subnet A are often unable to connect to the core switches in the LAN.
Considering that workstations in other subnet
The discussion of transmission networks and addressing networks recently read the book "Information Technology in the cloud age", which is quite rebellious. It is pointed out that the age of resource abundance is approaching, and the network theory established in the Age of resource shortage must all be retried! The book sharply points out that many of the current theories are so-called "smart", or a repair, which is consistent with what I call "Tips,

Some netizen message asks a question: Why installs the operating system to be unable to surf the net. My answer is: the normal Internet access depends on three: 1. There is no problem with the NIC and its driver; 2. There is no problem with the system network connection settings; 3. There is no problem with the network provider "Freeway". For the specific analysis of ne
