Spring GraphQL is a new Spring Application integrating GraphQL, released by Spring this year. Thanks to the out-of-the-box features of Spring Boot, it allows for the quick construction of a usable GraphQL service. However, despite its usability, the documentation leaves much to be desired, especially for some advanced features, which require self-exploration through the API documentation.

After brushing up on some videos about political economy and philosophy on Bilibili in May, I rekindled my interest in this area of knowledge and started following some up masters to learn more. Among them, I particularly enjoyed Weimingzi's discussion on the topic of 996. I found it insightful and inspiring, so I decided to jot down some thoughts on the matter.

I revisited the CSS selector knowledge in the MDN documentation and recorded it as a note.

I've been using the double pinyin input method for over a month now, and I've pretty much mastered this skill. Now, I primarily use double pinyin as my daily input scheme. In daily use, I haven't encountered any major issues, but the advertised significant efficiency boost isn't exactly noticeable. However, I've grown accustomed to it and will likely continue using it.

I got up early in the morning and found out that the domain I've been using for two years is due to expire in a month, reminding me to renew it. After dealing with some things, I went to renew it, only to find out that the renewal fee is 72 yuan per year, which shocked me. It was only a few yuan when I first opened it, and the first year's renewal was only about twenty to thirty yuan. The change was too drastic, and for a small personal site like mine, it's indeed expensive. I checked the current domain prices and found that the price of the .club suffix is indeed uniquely expensive, even more expensive than some .cn suffixes, which is a bit outrageous. So, I decisively chose to switch back to the .top domain I first used, which only costs 25 yuan a year to renew, and with the first year discount, I spent less than 60 yuan for three years.

On the other hand, changing domains also has quite a few costs, and the longer you use it, the higher the sunk cost. Accumulated SEO and RSS subscriptions are difficult to follow the domain switch and convert over, and may need to be accumulated again, and various statistical analyses may need to be discarded. But it still needs to be done, after all, the characteristic of the internet should be open and free, and should not be overly constrained.

The site has now moved to the domain https://scottyeung.top/

Recently, I have been collecting and processing a large amount of data, which usually involves converting XML/text format data into relational, structured data for easy export and direct analysis, especially formats that can be directly analyzed by pandas (csv/json). Therefore, I need to use a mysql processing library in Python. Since I was looking for a processing library, I decided to go all out and choose a library that supports ORM. So, I chose SQLAlchemy. After using it for a while, I decided to write a record to remember the commonly used things during this period.

SQLAlchemy is an open-source software under the Python programming language. It provides an SQL toolkit and Object-Relational Mapping (ORM) tools, mainly to meet the following needs:

• Provide common operations on databases: add, delete, modify, and query
• Provide ORM functionality, which can turn the operating unit into an object, so there is no need to write sql statements for hard coding/decoding parsing data
