Tags: assembly, system-utility, size-optimization, linux, x86-64

Score: 6.3/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 3)

This is an extremely minimal (298-byte) x86-64 ELF executable that reads and displays laptop battery status from sysfs. It's interesting as a technical demonstration of extreme size optimization and low-level Linux system interaction in pure assembly.

Target audience: systems-programmers, low-level-developers, embedded-developers
