Show HN: Zen Lake – 50B-digit π computation on modest hardware

I computed 50 billion digits of π using y-cruncher on a 10-year-old PC. The run took ~22 hours and used a reproducible setup I call Zen Lake Architecture. It isolates swap, binaries, and output for stability, and the README is minimalist and poetic.

The goal is to democratize high-precision computation and make trillion-digit π runs accessible to students and researchers worldwide.

GitHub repo includes English and Japanese README files, benchmark logs, and MIT License. Feedback and reproducibility reports are welcome.

“The lake where π swims is made of 64KB grains.”
