My name is Yi Liu (刘毅). You can call me "61" or "Hapoa". I was borned in 1990s.
I focus on software development and AI, and at the same time, I'm a strong advocate and believer of Open Source.
In spare time, I like reading, watching movies, travel and photography.
I like cats very much, because I think the purr of cats is the most beautiful music in the world and above all, only cats can quietly accompany me all day, or more.
"subetter" is meaning "show you better". Better sharing, better explanation, better presentation.
