field notes

Favorite fragments from the lab.

Cloudcode, memories, friends, and the little things worth showing.

status report

I'm Haruka Kanemari, also known as Rumi. I build Cloudcode hosting and learn security by making real things run.

Learning security, servers, and how to keep shipping anyway.

Hardware, hosting, experiments, and mistakes that became lessons.

Mostly keeping Cloudcode alive and side quests running.

proof of work

Not polished case studies. Real builds, real servers, real weird bugs.

main build

A hosting project for people who want servers without the boring control-panel mess.

side quest

A scrappy infrastructure experiment, mostly useful for learning what breaks under real users.

research

CTF reps, Linux hardening, network weirdness, and defensive break-fix practice.
