Art, a thought

Finished reading Kenneth Clark's Civilisation. I can't say I actually understand the book, because nearly every item he was talking about and describing with passion and logic, I had little idea. I barely recognized some names, and very little of the artifacts. Sculptures, some; paintings, nearly none; background ...


Tencent & Opium

Listening to this talk this morning, the thought hit me. How do you look at this game?

Games, in my humble opinion, are just, bad. I know it's unfair to say so since I have grown out of that addiction phase, and every boy/man will go through that ...


What does IT system bring

After long thoughts, I believe I have come to the conclusion that there are only three things that technology should bring, would bring, and should their objectives:

  1. information repository: everything is saved, time stamped, digitized, and probably even structured.

  2. efficiency: this comes from the fact that data inputs are sanitized ...


Lost jobs, not really

These days, everywhere you turn, there is talk about AI, and one primary theme is the human fear of being replaced by robots, thus resulting in huge waves of layoffs and job loss, which then leads to social turmoils, revolutions, and government collapses. Horrible.

But if you think of it ...



Watching the Civilisaiton Youtube, what a fantastic topic and description of western civilisation! This is quite interesting especially with the backdrop of Jared Diamond's Guns, Germs, and Steel, which I found it godly convincing as I was first introduced to think about the history of human civilisation through his ...



Man wasn't that annoying! Listened to this book on the way to outlet yesterday, and the language it used annoyed the shxxt out of me. Let me explain why.

Total attention

The content is actually fine. There is a total sum of attention consumers can provide:

total consumer attention ...



I was listening to this talk on Youtube about luck, and that got me thinking.

It's a cliche when people talk about luck, and someone gets lucky, or unlucky. It feels it is something we have no control over, and it is just randomly happened, for good and for ...


Math, the decline of the US

Came across an article tonight. The argument is actually not new — that US is now in decline and the only hard fact that no one is disagreeing, its leadership in technology, especially in computer related stuff, is shaken. The evidence, or its supporting argument, comes in two folds:

  1. that the ...


Data, Integrity

The first time reading "Trust" by Francis Fukuyama, I was deeply impressed by his distinction that Chinese trust is implied, such as inner circle of immediate family, friends, extended through marriage... while the Western version is explicit, for example, the credit score system.

Now we have data

With China's ...


Can you innovate?

This has been a topic on my mind for quite some time now ever since I worked in Shanghai in 2016 and witnessed things that quite annoyed me, especially from a software engineer prospective.

So the backdrop is that Chinese people have been encouraged by the country's phenomenal success ...


Charm Ansible integration

Let's face it. Ansible has the mouth (and market) share these days. For our modeling purpose, we are to utilize its procedural strength to carry out actions, which provides an abstraction instead of coding in charm's Python files.

Design objectives:

  1. Design as reusable layer(s)
  2. Be compatible with ...



I have pretty low tolerance of BS. The hot topic of AI bothers me a great deal, because it is being discussed by too many ppl who have no context. It is becoming just another buzz word rolling off your tongue to make you sound sophisticated and smart. But no ...


Love till past

很多人都i知道,浪漫的爱情里,两个人都怕时间太短,都说要长相守,两不忘。 最浪漫的话,是陪你慢慢变老。 Then this morning I had another thought.

All families have some burdens that trouble them, regardless how wealthy they are, how wonderful they look to outsiders, how much love they have for each other. There just isn't one single, perfectly happy, worry-free ...



This is an interesting thought. I am listening to this talk show about 三里屯, and guests are discussing the come and go of bars in this place. For those who don't know this place, it's a section in BJ that has a lot of bars which aggregated young ...


A color

This is interesting. I am at the nursing home eating, and suddenly realized the color of the book cover that I'm reading is nearly identical to the color of the food containers. You know what? I have never noticed this color before, nor would ever thought I will give ...


Zebra line

Walking on the street in SH, I just realized what is wrong with this place. So I was walking across this giant intersection, and I do mean giant because everytime I had to put in the high gear and used my dash speed at the first moment the walking sign ...


Sound of silence

What is everybody looking for? Identity? I see people in the middle of the social rung are all searching for something. Waking up this morning and walking on the street, the place was certainly busier after the holiday, more ppl, more cars, more purpose. Do ppl at the bottom of ...


Girl's love

Watching all the little kids running around at this public square in a summer evening, I was thinking to myself, "boy, that's a lot of kids. And each one of them came from a man and a woman, and they had to have sex at some point to make ...


Charm layer-basic

Have you ever wondered what layer-basic is for? and why every charm needs to include it? In this article we will take a look at its code base to decipher this mystery.


We already know hooks are hardcoded. Juju expects certain hooks and hook sequence is always executed in ...


Irresponsible response

Doesn't the title sound like a tongue twister? That's where the irony is. How can you make a response irresponsible? and what does it give? Any harm done? Does it matter? What does it mean when it happens? Why do ppl give such response? and why would ppl ...
