Optical file transfer out of an air-gapped machine. It renders a file as an animated QR loop on the isolated screen; a phone scans the loop, and the far side reassembles and verifies it hash-by-hash.

A data structures and algorithms course, from first principles to interview-ready: 38 chapters with traced, tested code, and LeetCode problems whose every solution is verified in Go, C++ and Python.
