Amusingly, Chen's article refers to the Wikipedia page as evidence that Tony Krueger did the port. The article's evidence for that in its latest version? A link back to Chen's article...!

To make the chronology clear:

• The Wikipedia page from before the reference to Chen's article was added: https://en.wikipedia.org/w/index.php?title=Chip%27s_Challeng... — it cites two sources for "coded by Tony Krueger" ("About box from the game") and for "written [by Krueger] in a single summer" (a forum post).

• Chen's article mentions "Tony Krueger is remembered in Wikipedia as the person who ported…", then adds a footnote: “Probably not as widely documented is that he accomplished this without the source code: He reverse-engineered the MS-DOS version and then reimplemented it for Windows.”

• The Wikipedia article then cites Chen's article for this additional information.

It's all fine and proper. I've just edited the citation to make this clear again.

FWIW, the citation to Raymond Chen's blog is specifically in relation to the claim that it was reverse engineered from the MS-DOS port due to the source code being unavailable.

Prior to the edit there was a citation to the game itself for both Tony and Ed Halley as the game's development but the guy who added in the reverse engineering anecdote from chen's blog split the sentence so that the citation for the names of the game's developers is only applied to the other guy.

Chen doesn't use Wikipedia as evidence that Krueger ported the game. He's pointing out that this is what Wikipedia mentions as most notable, and then adds another thing notable about Krueger, the squigglies. If you read the Chen's whole article, he adds more details about the port at the bottom, so he's clearly aware of it. It's fine to use the article as evidence for the port.

These kinds of circular evidence chains do sometimes happen on Wikipedia, but I don't think this is one of them.

Wait, that's illegal.

There’s an xkcd for that but I’m on my phone and too lazy to look it up.

Citogenesis!

Can't believe we got to see one in the wild, and with clear attribution to boot.

I have left comments on HN and Reddit and then found them rolled into Google's AI search summarizer OR the knowledge box with _extreme rapidity_ such that when I went, mere moments later, to go re-check some fact I had cited, I found my own comment at the top of the results, repeated back to me, but with authority and gravitas, ensconced in the austere trappings of the knowledge box.

in addition to a relevant xkcd, there is also a Wikipedia article about the phenomenon and a behind-the-scenes list

But that didn't happen. See comments above by svat, snickerbockers, and InsideOutSanta.
