I had used "VMware", one of virtual machine(VM) software before more than ten years.

I predicted that "in the near future, we are going to take out not a client but a sever." and it will be realized indeed.

Now I use a VM software, that name is "VirtualBox" presented by Oracle Co.. The software can export and import a guest OS with ease unbelievably.

We can take out a whole OS system including softwares, so we don't have to worry about compatibility of hardware and device driver problems.

According to the outsourcing software development, we are asking not program codes but Guest OS including the codes, absolutely.

Because, we don't care how many Guest OSs are included in a PC server, now.

Yes I know well. Most people cannot understand what Ebata is writing in the above.

Simply speaking,

"It becomes natural in the IT world that residents in a same combo are likely to never say one word in their life"

The Guest OS is going to not be visited by any clients, and just waiting a client as long as their life. No one knows them and just live their life alone.

No-no, I am almost close to tears when writing today's diary with grief.

In conclusion, this diary has a luck of efforts to be understood by reader at all. These things can happen.
