Use RHEL server qcow2 as sandbox

Copyright @ Lenovo US

The closest thing RHEL has to a cloud image is a qcow (download from here). This image has disabled root password, and disabled SSH access ← so what the heck!?

Method 1: modify image directly

Really ugly solution. Anyway. On a Ubuntu 16.04, install guestfish and libguesttools, then:

create root ...

These notes are based on Satellite 6.3. There are minor difference between 6.2 and 6.3. Grasp the concept here, and hopefully you will have a good understanding of the Satellite models and procedures.


  1. One satellite server (master server), and 1+ capsule servers.
  2. The Satellite Server is ...

From 4th grade class weekly message of 4/8/2018:

Positivity Project News:

Starting Monday, we will begin learning about integrity. This is doing the right thing when nobody is watching. People with integrity practice what they preach and maintain a consistent pattern of behavior aligned with their values. They ...

Too little sympathy, too much generalization

Noah is a taking social intelligence course. A conversation gets me thinking, what is to measure a social intelligence? My observation of kids (and adults, too) is that we need sympathy — the feeling that your action will affect others in this or that way, and the uncomfort the others display ...

Django to REST

I have been building Django based web application for a while now. One design/request I get often is a REST API. Once the model data is exposed in REST, one can truly build a complete separate frontend ...

Moving, and a big trip

The past weekend was the big moving day. Things actually went pretty well, except the morning pick up of U-Haul. What a terrible customer service they had! Well, it started with my fault really by forgetting to bring my driver license. Nonetheless, the only service was not helpful ← and it ...

A song

It's a morning that you are touched, by a song. Quite out of nowhere when I was just flipping through Youtube trying to find something to watch. Then there was this movie, I probably have watched it before. I can't remember when now. I don't even recall ...

Science disease

Another Chinese new year. But what came to my mind this morning was something quite peculiar, if not irrelevant to the scene — what is science, or being scientific? Noah is taking some science class on rock and mineral, and I have just written about euphemism. This word, science, has been ...

To Nianyi


Haven't been a while since I wrote you anything. I'm listening to this movie while working, and felt I have something to say to you.

I want to say I'm sorry, sorry for being such a ass recently, for not speaking to you much these days ...

Sigh. Life is indeed full of puzzling person and phenomenon that annoys me and I found myself always wonder why they do that and what I have done to make them act that way (or regardless what I have done and do, they are just like that). Why?

The new ...

Big D

This has been a long past due as I have been thinking about this for the last few days, and have attempted to write a letter a few times, but always not feeling the feel, and when the feel was there I was usually busy running around for things that ...

I have to say, I haven't read an entertaining book as Class for a long time. This book is just stimulating, fun, and sharp. It actually hurts. It describes sooo accurately of what I feel about many aspects/signals in life that I come off with a much clearer ...

I have been doing a lot of thinking recently, about human society. There are multiple themes in my life and in my thinkings that I find them interesting, disturbing, annoying, and saddening. The more books I'm reading about historical events and views, the more I question how a society ...

Remembering China

This is a quite fascinating book. Actually I started to find myself always fascinated by early first-person account of China. I have this curiosity of what this country was like, and everytime I read a book like I always found myself keep thinking how similar peopel then to people now ...

Teacher: If you have 10 chocolate cakes and someone asks for 2, how many do you have left? Me: 10. Teacher: Okay, well what if someone forcibly takes two of the cakes, how many would you have left then? Me: 10, and a dead body.

This thought has been haunting ...

Best yoda lines

Noah wrote a sheet he titled best yoda line from the clone war. It's both philisophical, sophisticated, and cute. He has also said quite a few things recently that shocked me.

Episode 1: taking a trip

Me: do you want to go on a trip with me? Noah: No ...

A minor upset

I think, well, actually not that I think, I feel, I feel it with me, that I have grown very much impatient with Noah's mom now. This is really sad. I think there is something up to her life recently, too — she was not being patient with Noah, actually ...

Age and maturity

I admire youth. It is a wonderful treasure to have since there is nothing you did to have it, and nothing you can do to retain it. You have it when you have it, then it's gone. But youth is also an awful curse since you are cast into ...

Half the world

Indeed a fascinating book, Where half the world is waking up by [Clarence Poe], a person born in North Carolina writing about China, Japan, Korea and India in the year of 1911. What a view he had!?

Certainly I got to learn about what these countries were like — more backwards ...

Got a book and it is truly disturbing, Rape of the Mind. So the mind manipulation has been developed to the point that is highly refined, highly scientific (you know I always have reserve about this particular word this days), highly systematic, and highly predictable. And this is the really ...
