Programming hobbyists love a challenge. Getting Linux to run on, well, anything is a challenge many find irresistible. The latest example involves getting it to run on the legendary Commodore 64. Getting it to run on a Mac is one thing, but doing the same on a 40 year old computer with 64KB of memory is quite another.
Developer Onno Kortmann (via Slashdot) used Semu, a light RISCV32 emulator, and cross-compiled it with llvm-mos, allowing the code to run on the C64's MOS Technologies 6502 processor. It needs to be pointed out that this was done via an emulator and not on real hardware, though it's only a matter of time before that happens.
