Yeah, it's a dupe. Flag it and move on. BTW the "different site" is the author's.
It's not worth linking to the original and updated version of it by the author instead of the wired post about his work?
As much as I prefer to link to the definitive version of everything, in this case since we already discussed the Wired version my dislike of dupes takes precedence. Don't take it too hard; I'm not representative of the general HN membership. I didn't realize it was updated, though.
