I'm playing with a tape drive for backups, so I asked a local model to rewrite LTFS ( https://github.com/LinearTapeFileSystem/ltfs ) in Go.

I gave it the reference C implementation, the LTFS spec from SNIA, and asked it to use the C implementation to verify the correctness of the Go code.

LTFS is a pretty straightforward spec, so it made a very reasonable port within about 2 days. It's now working on implementing the iSCSI initiator (client) to speak with my tape drive directly, without involving the kernel.

Edit: the model is Qwen3.6-35B
