Fundamentally, almost all of the major software, even open-source software, was designed before the advent of mirror-based container technology. This means that putting the software in a container is equivalent to a platform migration. This also means that some programs can be easily migrated, while others are more difficult.
I carried out mirroring-based container-related work about 3.5 ago. So far, I've containerized a lot of a

Failure phenomenon:
Computers that randomly install WIN8 typically do not have a system recovery CD, and if you replace another system, it can be cumbersome to have no discs when you need to use the WIN8 system again.
Reason Analysis:
We can use the "Windows 7 File Recovery" feature from the WIN8 system to make the recovery CD from the line or to back up the mirror to the mobile hard drive to solve the problem.
Solution:
1. Open the Win8 Control

Do flash may be blurted out: set a mask just. Unfortunately CSS is not flash, there is no that set. We only have to dig throu

The PIP installation package is a common occurrence for Python development users. But foreign source download speed is too slow, waste of time. And there are frequent installation errors after downloading. Therefore, the PIP installation source to replace the domestic mirror, you can significantly improve the download speed, but also to improve the installation success rate. Domestic Sources:
