Could you build this?
No Hand-crafting a functional 301-byte x86-64 ELF executable requires elite assembly programming, ELF binary header hacking, and deep binary golf expertise that AI assistants cannot reliably hallucinate or generate.
What it would actually take: This requires low-level binary golf, hand-written x86-64 assembly, overlapping ELF header fields (e.g., using the program header overlapping the ELF header), and utilizing raw Linux syscalls with zero runtime overhead. Specialized knowledge in the Linux kernel ELF loader, x86-64 machine code encoding, and binary optimization is required to make every byte execute valid code.
Discussion
20 comments analyzed.
Competitors mentioned: bat_mon - X11 battery monitor (50kB with GUI and JSON parser)
Concerns raised: Segmentation fault and ENOMEM errors on some systems, Excessive p_memsz value causing compatibility issues, Not standards-compliant ELF, tricks kernel into loading, Infinite loop on error with no user feedback, Kernel version dependent behavior
Feature requests: Print error message instead of infinite loop, Support multiple batteries with status display, Auto-generate one-liner install rule in Makefile
