> Change one byte.
Most resubmissions are submitted by people other than their authors, who are typically not in a position to change any bytes of the content.
In the present case, speaking as the last person to submit this one (more than two years ago), I don't see that there's any harm in it at all. If this is still interesting two years since it was last discussed on HN -- which clearly it is -- then good for the submitter, who has provided the HN audience with something interesting to read.
