But it's just forwarding the filesystem mtime.

There's no exif data for this image, which totally checks out because it predates the exif format.

It's like some sort of weird comedy skit.

I believe it's the equivalent of the [XY Problem], except in the context of an (imagined) disagreement. It happens because the second comment is misinterpreted to be arguing against the first when really it may be in addition. It can be fixed by readers taking a charitable interpretation of the second comment, or by the second commenter's author making it clear that they're not disagreeing, as in,

> > > Yes, and 6 isn't prime, its factors are 2 and 3

I'm pulling out these two comments because it's a much more common pattern than just this comment chain; I think it happens all the time with text in general. Actually, I'm commenting here because it just [happened to me] in a different context. Someone I thought I was arguing with turned out to mostly agree with me — but because we failed to re-affirm the parts of each other's arguments that we agreed with, it seemed like we disagreed more than we did.

It's like some sort of tone-deaf comedy skit.

This is low-effort humor. I took the comment above and replaced words with memes from anime, tech, and earlier in this conversation thread. There's no (intentionally) meaningful relation between rem and Rem, or the number 6, I was just pattern matching things that sounded similar. Basically the equivalent of an "I hardly know her" joke. Funny only for the meme value, and not what I come to HN for.

In this particular thread, ^^that^^ is the joke — that we mistake unrelated comments as meaningful replies.

PBM is probably older than GIF and still has software support

https://en.wikipedia.org/wiki/Netpbm#File_formats

though apparently not directly in browsers! (I would have expected it did, but I couldn't get browsers to render PBM files directly.)

The list of all webservers used to fit on a single page, which might be a good starting point. However, at this point I believe anything still functioning might fit your definition of a "mirror" as few things still speak HTTP/0.9.

dated 30 Sept 1992, which is pretty old as far as the web goes.

I would agree that an archive ala archive.org should be disqualified, because few people would go to that site as the original. To me, Sunet is a little more grey, because while it is an archive/mirror site, many people used it and linked to it as if it were the primary source and not just an archive site. Before the web was indexed and search engines became popular, large mirror sites were the easiest way to access a variety of content, all in one place.

(Meaning the the current maintainers could fix this by doing a single "ln -s" command, ehrm. @ acc.umu.se.)

Anyway, a previous webmaster of this site replied another time it was posted here, https://news.ycombinator.com/item?id=23709016 if anyone's curious.
