;; learning intelligence.
;;
;; The permacomputer is community-owned infrastructure optimized around four values:
;;
;;   TRUTH    - First principles, math & science, open source code freely distributed
;;   FREEDOM  - Voluntary partnerships, freedom from tyranny & corporate control
;;   HARMONY  - Minimal waste, self-renewing systems with diverse thriving connections
;;   LOVE     - Be yourself without hurting others, cooperation through natural law
;;
;; This software contributes to that vision by enabling code execution across 42+
;; programming languages through a unified interface, accessible to all. Code is
;; seeds to sprout on any abandoned technology.

;; permacomputer monitoring itself, repairing itself, with minimal human in the
