Irregular Apparatus Lab (>_<)

I build small machines for oddly specific problems.

A GitHub Action that fakes your contribution graph. A CLI that performs surgery on your liked songs. A city sim with a stricter data flow than most production apps. Every one gets a unit number the day it starts. The rest are still in a folder called /someday, pretending they'll be ready next week.
