About

I'm Minsoo Choo, a computer engineering student at the University of Waterloo working at the FreeBSD Foundation.

What I Do

At the FreeBSD Foundation, I contribute to one of the most important open-source operating systems in the world. I'm also an LLVM committer, focusing on improving LLDB for FreeBSD, making debugging better for developers working on the platform.

As a CHERI ambassador, I work with microarchitectural innovations that are shaping the future of processor design. CHERI (Capability Hardware Enhanced RISC Instructions) represents an evolution in computer architecture, and I'm excited to explore how these hardware features integrate with operating systems.

What You’ll Find Here

This newsletter is my space to share insights and updates from the intersection of systems programming and hardware security. You can expect:

  • Technical Deep Dives: Posts about CHERI capabilities, RISC-V developments, and kernel programming insights
  • Project Updates: Progress reports on my design team initiatives and personal technical projects
  • Work Chronicles: Experiences and lessons from my embedded systems work
  • Life Notes: Occasional reflections on the journey of a computer engineering student navigating the world of systems programming

Philosophy & Transparency

On AI Tools: I believe in transparency about tool usage. While I leverage LLMs for research (gathering resources) and refining my writing (wording and proofreading), all technical insights, opinions, and core content come from my own experience and understanding.

I use the following prompt on Claude Opus 4.6 for refining my writing:

Below is my article. Make it sound like a professional software engineering post. Make it smooth and reword if needed.

<article>

After Claude completes its revision, I carefully proofread to ensure no meanings were altered, nothing was added that I didn’t intend, and the content remains authentic to my original thought.

On Accessibility: All posts are completely free to read. If you choose to subscribe, consider it a donation to support my work and the time I invest in sharing these technical explorations. Your support helps me dedicate more time to open-source contributions and educational content.
