CS61B
cs61b-spring-2025
My first time learning data structures systematically — UC Berkeley's CS61B homework, projects & labs, all committed in public.

I'm liangshuo — a self-taught builder chasing the warm experiment of the Beatles and the surreal depth of Pink Floyd… one data structure at a time.

about me
hey, I'm liangshuo ✌
I go by olisNeuron online. I'm a self-taught programmer learning systems and data structures straight from the source.
Right now I'm working through UC Berkeley's CS61B (data structures) and CMU's 15-213 / CSAPP (computer systems), turning homework and labs into a public trail of code.
I also tend a personal knowledge base — an ever-evolving LLM wiki — where raw material gets distilled into notes I can actually find again later.
currently wondering…
- how an agent turns a single sentence into a tool call
- what happens between source code and a running program
- how to organize knowledge so it can be found again
- how math, systems, and AI fit together
“What I cannot create, I do not understand.”
