I currently rarely use R for data processing or cleaning because my daily work involves a lot of string extraction/processing, which is difficult to do in R. Additionally, the error tracking in R is very demanding on code proficiency and experience, making it almost unbearable for me to write and maintain R code (I tried at a previous company…). However, recently one of my colleagues asked me to use R to complete such tasks because he only knows R. In the process of copying code, I discovered another reason why I don’t need to use R for this type of work…

A long time ago, I was interested in a special operating system made in China called FydeOS. It is based on ChromiumOS and is a Chinese version of ChromeOS. The main idea behind this operating system is that many people do not need high-performance terminal computers for work; they just need an entry-level device that can access essential work services through a browser.

Recently, while helping a colleague create plots, I uncovered some new issues and solutions related to ggpubr and survival analysis packages. Here are the records.

A while ago, I implemented an interesting interactive data processing case using Dash. Here, I’ll record it.

I’ve been extremely busy lately, with too much work to finish… so I haven’t had much motivation to write. However, this time I’ve applied what I’ve learned in the past six months to build my first web app with database operations, which is worth commemorating. Although I’m short on time, I’ll start with the text and add images later.

Due to project requirements, I finally took the time to actually look into how to use Flask. Here’s a record of what I learned.

From childhood to adulthood, my biggest motivation has always been playing games and looking cool… Today I wanted to play Monster Hunter 4G but couldn’t get back to Guangzhou, so I played it on my 5-year-old 3DS. Since it’s an old game that wasn’t very popular in the Chinese community at the time (Ping’s Dex was inconvenient due to system issues), it’s hard to find Chinese resources. To play the game better… I turned to an app that requires watching ads to earn points, which can then be used to exchange for specific equipment functions.

Today I encountered a plotting problem and learned a new small trick, so I’ll record it here.

I previously used __enter__ and __exit__, which I had heard of before. This time, my program development is mainly object-oriented, so I needed to use more methods to achieve some useful features i...
