Hey, the author of the blog here. English is not my native language. I did try to write the first section, but for the later section, I wrote a rough draft, but then I had that intrusive thought that people would not like it because of my poor English and too many typos, so I just told LLM to make it better, and that's how it ended up like this. While my intentions were right, my method was wrong. I will improve and fix my writing. I have taken down the blog for now. I don't want to waste other people's time. While it has good content, the presentation is wrong!
