The rainy weather has been continuous for almost two weeks, and the rainy season of this summer feels earlier than previous years. Last weekend, the Premier League matches of this season were already finished. Manchester City locked the Premier League title two rounds in advance, and the final closing battle was no longer suspenseful.
Let's review some things done this week:
Tools#
Recently, I have been considering how to implement a bot that can train custom data. The principle is to use the OpenAI API, LangchainJS, and vector database to complete it. Databerry is a no-code platform that supports using custom data to implement a ChatGPT Agent, and the overall user experience is good. However, the limitations of the free version are too many, and I haven't had a chance to experience it in depth. The quota is almost used up.
Last week, I also participated in a hackathon competition and finally did a "full-stack" development - frontend + smart contract + PPT + video, almost all done by myself. Gamma was used for assistance in the PPT part. It saved me a lot of time. I just need to throw the README of the project into gamma as an outline, and it can help me complete the framework of the PPT. And there are many awesome styles to choose from, and it's easy to modify the layout.
yt-fts is a command-line tool that can perform full-text search on subtitles in YouTube channels. The principle is to use yt-dlp to download the subtitles of all videos in the channel and store them in an sqlite database for full-text search. The latest version also supports semantic retrieval using OpenAI embeddings.
Podcasts I listened to#
This episode invited Evan You as a guest. I really didn't expect that Evan's singing would be so good to listen to 😂. After listening to this episode, I specifically listened to Jay Chou's "Spring Wind Blows" a few more times. This episode didn't talk about specific technology, but shared Evan's life in Singapore and how to make decisions, and so on. One memorable conversation was - when talking about the reasons for Vue's success, he said, "There may be many people whose technical skills are equal to or even surpass his, but what sets him apart is that he understands the needs of users better." And also the timing, at that time, frontend engineering was just getting started.
Books I read#
- "On the Right Bank of the Argun River" - Chi Zijian
This book depicts the vicissitudes and current situation of the Ewenki people over a hundred years. On the land where the Ewenki people have lived for generations, there are reindeer, trees, rivers, moons, and gentle winds that accompany them day and night. The author's writing style is very beautiful. I remember encountering her works frequently in reading comprehension during high school.
Currently, I have only finished reading the first chapter. I will talk more about my feelings in the upcoming articles.
