Ronin GitHub

Every question runs deep.

Ronin means wave person.

Hokusai's woodblock print of a towering blue wave curling over three boats, Mount Fuji small in the distance.
Katsushika Hokusai, Under the Wave off Kanagawa, about 1830–32.

浪人, rōnin: the characters for wave and person. A samurai with no master, going wherever the road leads.

Ronin does that with a question. No syllabus and no feed deciding for you: pick a thread, follow it as deep as it goes, and the trail is still there when you come back.

Hiroshige print: a column of ronin crossing a long wooden bridge in snow while two boatmen wait below.
Utagawa Hiroshige, The Loyal Ronin Crossing the Long Bridge, about 1840.

Wandering, never lost. Every concept on the map shows the path that led you to it.

Ask once. Follow it down.

Ronin turns a question into a small, expandable map of ideas. Pick a concept to read its context, follow a branch, and come back to the trail later.
