这本书是我偶然看一本历史穿越小说得知的，通过这本小说我知道了谁是苏颂，谁是韩公廉，沈括除了写《梦溪笔谈》还具体干了啥，也知道了在几百一千年前的中国历史中一些神奇的发明。作为完成了九年义务教育的我来说，谈及开封只悉晓清明上河图，古代科技只认四大发明，这在现在看来无疑是可笑的。

I have been using SAXO for three years and Interactive Brokers for more than one year, and recently I have decided to switch from SAXO to IB completely, but I could not find a proper instruction on the Internet.

这个问题说实话有点烦。

Today I have successfully migrated my current Airflow setup from v1.10.14 to v2.0.2. This article will not be a very detailed step by step guide for upgrading, instead I will introduce the general migration step worked very specifically for my setup, and share some of the problems I encountered during the process, and finally some general feelings with Airflow 2.

Data engineering jobs are really popular nowadays, mostly contributed by the rising demand of data insights and data driven decision making.

I just reached Diamond 3 on American server in Starcraft 2. Yeah yeah I know NA server is easier compared to Asian but it is still a diamond, and I am pretty happy. For this particular season I have not played a single game of cheese, but I have, sadly to say, counter cheesed opponents. Most of my games are played with heavy reliance on macro.

So I am trying out Notion, so far it looks ok. With all the fancy templates it looks like it can do much more than Bear, but I have also heard rumors about how it can get pretty messy after you have a lot of stuff. It’s free for personal use anyway so I thought I want to give it a try, at least the table structure is pretty useful for me.

So this week I was pretty serious in my piano practices, played for one hour everyday except on Friday, it has become an important part of my daily routine.

I have been on some sort of movie spree for a few nights in a row, without dropping my piano practices of course, and I ran into this movie called Knives Out a few hours ago.

This is a bold title I know, and I am not even a data analyst.
