Now we are entering a new digital age — digital content or service subscription age.

If you ask me, what is the most digital change in the recent 10 years, I would say “digital subscription service” is definitely one of them.

With the monthly payment or the yearly payment, people get access to the most powerful software which is always updated to its newest version or get access to the best content provided by the world’s leading media.

Nevertheless the monthly payment seems to be quite a little compared to the price paid once a time, its cumulative cost is…


The Forms of Graphs

There are so many graphic forms can be made by Tableau.

There are also so many algorithms can be put behind for each graph.

The combination of graphic forms and algorithms can lead to thousands of forms of visualizations. Maybe the visualization can also be called patterns.

Here are the sample graphs I made. And let’s see something different. The data is analyzed for US stock market on daily basis.

1. Area Distribution Chart Separate

2. Area Distribution Chart Combine


Folder and File System

First of the first, I’m not a programmer and I don’t like coding. I am the one who like to use the tools to solve the problem and unravel my curiosities.

When the first time I’m using Tableau, I thought, yes, this is exactly the tool that I want to let me understand what the data is and what the world is.

I was using excel for data analysis before which can draw regression lines base on the data inputed.

However, that’s not strong enough for data visualization. Maybe Excel can do the visualization too. But I don’t like to…


A lot of people are just talking and talking.

So as a lot of people are just reading and reading.

Only Nike told you:

Just do it

“Do it” is the most authentic and warm hearted advice to be told. The knowledge of this world are coming from “Do it”, not from “Talk about it”.

Only “do it”, can lead you to a successful result, and it can lead you to a failure too.

The failure is always complied with success and it’s just common. Probably there will never be a success and it is common too.

No matter failure…


As a long time Tableau user, I tried using Tableau CRM recently and it did blow mind.

Yes, it’s Artificial Intelligence standing before me first time in my life. And I’m using it for security analysis first time.

Below is the advantage of Tableau CRM

1. The dataset format is easily converted from existing Tableau dataset.

Tableau CRM fits into Tableau desktop pretty well, especially the data format. And it fits to my Tableau system pretty well too. It only takes a few steps to convert the current dataset to the dataset fit to Tableau CRM.

2. The CSV file doesn’t have to be big.

To my surprise, the dataset required for Tableau CRM is CSV file.
Because Tableau CRM…


Meditation seems becoming more and more popular these days that I don’t know why.

Because I did meditation since I was young at the age of 15 that can surprise some but which I thought it’s just common Life.

I was raised in a family believing Buddhism and Meditation is just part of the belief.

Nowadays, there are some Tech enrolled in the meditation which provide the guide to do the meditation with some audio or video instructions only by your mobile phone which are nice and seem cool.

But that’s just a tool to help people relax.

What am…


I used to travel a lot and I liked traveling. However, time changed. I’m not willing to do some business travel any more.

I just want to stay with Family. I hope my office is not far from my home and no travel required or it can be a home office. That requires some skills. Most of us can’t find a job like this.

Anyway, the job with no travel is better than with travel. Because you can see your wife and kids everyday.

People used to be living like this. But nowadays are totally different, so as the skills.


I’m a huge Fitbit Fan so there could be some bias when I’m reviewing Fitbit. There are so many topics can be discussed about Fitbit such as Fitbit App, Fitbit Premium, Tracker or Smartwatch, Fitbit or Apple Watch etc.

No matter what, I just need to tout something. Let’s begin with Fitbit Sense — the most powerful Healthy Watch in Fitbit history.

I have wearing Fitbit Sense for about half year. I ordered it when it first came out. I had been Fitbit Premium user since it debut. And the Fitbit premium improved Fitbit Sense’s user experience a lot.

Fitbit…


Falling in love with it when first seeing it; The color is smooth and darling.

Not like an iPhone that has a notch, not like an iPad that has a button.

No matter horizontal or vertical, no matter which cover it has, it looks just square.

But I’m still not sure which shall I choose, small or big screen.

So I went to the retail store to have a look.

The experience of Apple Pencil is marvelous, double clicks to switch from pen to rubber.

No matter linked to magic keyboard

Or grab at hand

Even the VR experience
