This is all about

I chatted with my colleagues yesterday. Some files must be verified with MD5 to prevent tampering. My colleagues had a copy of the software and found that the problem was not serious, but they gave up when implementing it, the JDK is an earlier version. To add new features, you need to use the new JDK and upgrade weblogic, later, it was found that the upgrade involved too much, so it was difficult to move back.

Later I thought about how to do so many things about software?

Software upgrade is a task. When you delete a file, you don't prompt. It's just a matter. Before you delete the file, you don't back up the file.

When the software is too big, componentized, And the dll version is inconsistent.

It is a matter to be killed by mistake. If the manual is changed, it is a matter not to modify the manual. If the manual is changed, it is also a matter if you do not train.

In the final analysis, software is a tiring process.
