Sci-Fi Writer Greg Egan and 4chan anon Math Whiz Advance Permutation Problem | Quanta Magazine
On September 16, 2011, an anime fan posted a math question to the online bulletin board 4chan about the cult classic television series 'The Melancholy of Haruhi Suzumiya'. Season one of the show, which involves time travel, had originally aired in non-chronological order, and a re-broadcast and a DVD version had each further rearranged the episodes. Fans were arguing online about the best order to watch the episodes, and the 4chan poster wondered: If viewers wanted to see the series in every possible order, what is the shortest list of episodes they’d have to watch?

In less than an hour, an anonymous person offered an answer — not a complete solution, but a lower bound on the number of episodes required. The argument, which covered series with any number of episodes, showed that for the 14-episode first season of Haruhi, viewers would have to watch at least 93,884,313,611 episodes to see all possible orderings. “Please look over [the proof] for any loopholes I might have missed,” the anonymous poster wrote.

The proof slipped under the radar of the mathematics community for seven years — apparently only one professional mathematician spotted it at the time, and he didn’t check it carefully. But in a plot twist last month, the Australian science fiction novelist Greg Egan proved a new upper bound on the number of episodes required. Egan’s discovery renewed interest in the problem and drew attention to the lower bound posted anonymously in 2011. Both proofs are now being hailed as significant advances on a puzzle mathematicians have been studying for at least 25 years.

The Conspiratorial Hate We See Online Is Increasingly Appearing In Real Life
"On an online world that’s normalized ironic racism and shock trolling, it’s impossible to tell exactly who is a threat and who is just trolling. Perhaps the distinction is now irrelevant. Perhaps it always has been."

No, a former Kavanaugh clerk didn’t flash a “white power sign.” Here’s what really happened.
Back in February 2017, Pitcavage writes, a 4chan user proposed an effort called “Operation O-KKK” in which he and allies would, in the anonymous user’s words, “flood Twitter and other social media websites … claiming that the OK hand sign is a symbol of white supremacy.” Here’s the original 4chan post, as shared by KnowYourMeme:

The choice of the okay symbol for the prank, as KnowYourMeme editor-in-chief Brad Kim explains, was not totally arbitrary; “Sometime during the 2016 United States presidential election,” Kim writes, “Pizza Party Ben and Milo Yiannopoulos began making the gesture together at various events supporting the candidacy of Donald Trump.”

Memes do Not Exist: Memetics as Anthropotechnics – Woke Noumenon – Medium
The point here is that they have created a training regime which infects others and subverts them for a positive end of promoting simple fun, kindness, and affirmation. Where /pol/ asks you to pretend to hate minority groups for “fun,” /s4s/ asks you to just “pretend to be fun, nice, and creative.” And like that, it gets you. Even “rude” posts here can’t help but make one smile. Listening to one of the /s4s/ radio broadcasts left me feeling ecstatic for days, from being in such an unconditionally positive environment with boundless methods of expressing that positivity. This is not done through some “return,” but rather a radical uprooting — not of the postmodern ironic kind, but one of free creation. The very thing that makes /s4s/, the leading example of post-ironic humor, so revolutionary and subversive is that it says nothing. It has no rituals of initiation, no formal exercise structure, only a rallying cry around some principles that the user must find for themselves. There is merely exhilarating freedom of making your own sense. This is a zero-entendre game.
