Indeed. I would even dare to say most of /sci/ don't want to be associated with anime at all.

It's an anime website though.

How so? It's a very general-purpose image board and has a been for a long time.

I am more surpised that the other amateur mathematian appearing in this article is Greg Egan (He has a personal website on https://www.gregegan.net/ ). He is one of the best contemporary hard SF writers in the world.

Wow. Any recommendation where to start?

Schild's Ladder is my personal favourite.

Unlike sites like Reddit where an overarching hivemind will dominate the entire site to the point where your cooking, gardening and Reality TV subs will all contain American politics for some ungodly reason, 4chan still seems to be siloed in to specifically focused communities. Ignore /b/, /pol/, r9k and all the weeb stuff and you can find some properly good communities which remind me of the old internet. /sci/, /mu…

Good luck doing that on 4chan

Clicking around the previous discussions, it appears that the original question was posted on /sci/, a science and math board on 4chan, and not an anime board, as everybody who writes about this states. This is apparently an archive of the original post: http://4watch.org/superstring/ It's a question to a math community, using an anime meme template and referencing another anime. The discussion is very much not some…

I fear I'm responsible for this misconception. At first we didn't realise the proof had originated on 4chan – Nathaniel Johnston originally found the proof on Wikia, and the 4chan archive was only discovered later.

When I tweeted about it, I said “The best known lower bound for the minimal length of superpermutations was proved by an anonymous user of a wiki mainly devoted to anime.”, by which I meant Wikia (which was pretty anime-centric at the time).

I think, combined with the fact that the problem was posed to 4chan in terms of Haruhi, and because it makes a funnier story, that the anime angle has been a bit exaggerated.

Having said that, the author of the proof is not (to the best of my knowledge) a mathematician, nor does he have any apparent desire to publish his result in a conventional form, so it's still a pretty unexpected place for such a result to originate.

At one of my old jobs, the bathroom was locked with a 4 digit code followed by the key symbol. We jokingly made up "Bathroom Code" as an interview question/to nerd snipe each other instead of working, which was "assuming you don't have to press key, and that the bathroom door will unlock if the correct 4 digits are entered in order at any time, write the code to print the shortest possible test sequence to guarantee…

You know Ford/Lincoln had those buttons / touch strip in the door with the buttons labelled like [1|2] [3|4], and so on to [9|0]? There's a permutation list claimed to be the shortest that I used to carry in my PDA to impress friends that had one of those sorts of cars. If I recall, it was guaranteed to open the door in something like 32 button presses, but it may have been less. It was because there was no "start" o…

And in other fun knowledge, the f150 2016 has no way to disable that keypad. Short of taking apart the door and disconnecting it.

> It does make me wonder how much hidden knowledge is hidden in parts of the internet That was the shining hope of the internet. "Information wants to be free" and now it could be available to anyone with a modem vs just in university or municipal libraries. Now, we have megasites that dominate the web's attention with very trivial and banal content that makes looking for that information nearly impossible.

The worst are the information blackholes created by apps like Discord or Slack. Lot of technical communities are there nowadays, lot of ideas are just out of view from anything public.

One must hope that the spirit that compells malicious actors to archive private p*rn Discord servers on a publicly-accessible site eventually finds itself to people with access to technical servers. I get that everyone wants their secret hangout, but not everything needs to be a SCIF wannabe. Publish those logs.
