Bio
Hi, I’m Hao Lou. I also go by phyll1s0 online. I study Computer Science at Shanghai Jiao Tong University and work with Prof. Yu Feng.
I spend a lot of time messing around with code. Most projects start because a tool annoys me, a system makes me curious, or I just want to know whether an idea will work. Some get finished, some sit half-done for months, and some are rewritten from scratch. I’m fine with that. Building is usually how I figure out what I actually understand.
These days I’m mainly interested in AI and systems. On the AI side, I care about both the models and how they change the way people find information, work, and create things. On the systems side, I like compilers, operating systems, networks, performance, and reliability. I also enjoy frontend work and design. A tool should work, of course, but it should also feel good to use.
My projects move back and forth between useful and fun. Sometimes I’m solving a real problem; sometimes I’m just testing an idea. Vibe coding makes it possible to get a small project running in a few days, which is great, but I still care about the details and the decisions behind it.
When I’m not coding, I ski, play tennis and billiards, and spend more time on Steam than I probably should. Lately I’ve been playing Hollow Knight, CS2, and Zenless Zone Zero. I also like reading, films, music, and travel. I don’t want this page to make it sound like technology is my whole life.
This site is where I keep articles, projects, experiments, and notes from different stages of my life. It may be a little messy, and I’m okay with that. I mostly want it to be an honest record of what I’m interested in and what I’m working on.
Fun Fact
Why phyll1s0?
Why phyll1s0?
You might notice that my Chinese internet name, 凌灰音, borrows its sound from Lin Huiyin, the writer and architect. A smaller hidden branch of that joke is her English name: Phyllis Whei Yin Lin.
So phyll1s0 begins with phyllis, taken from that name. The final 0 echoes ling (林 / 凌) in Chinese, and the 1 is there partly because a computer science person is allowed one tiny piece of binary-flavored awkwardness. It is not perfectly logical, which is probably why I like it.
