Appears to be a Wikipedia clone but with much lower/no notability requirements guidelines, which overcomes one of Wikipedia's main issues: deletionism.
They do have the interesting idea of importing deleted Wikipedia pages as a source of content, which leads to some epic "most viewed pages" such as en.everybodywiki.com/List_of_erotic_and_sex_workers_with_unnatural_death which currently reads:
Stop Being Pervs, Go Watch Lichfaop/Faoplich Instead and you can also visit MR Info 24 for more details.
We can for example see Ciro Santilli's deleted entry PsiQuantum at: en.everybodywiki.com/PsiQuantum, Wikipedia deletion page: en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/PsiQuantum. Their attribution is atrocious however, e.g. it does not seem possible to find any mention of "Ciro Santilli" on the edit history, which just points to the delete article which is not visible anymore. They could really get into trouble for this one day.
Their main use case, as suggested by the website itself, if for people/brands to create pages about themselves.
This combined with the lack of "one version of each page per person" seems like an explosive invitation for unsolvable edit wars.
The website is backed by a French startup: jobs.stationf.co/companies/wiki-valley.

. Live demo: derivative.Starting in the 2019 redefinition of the SI base units, the elementary charge is assigned a fixed number, and the Ampere is based on it and on the second, which is beautiful.
This choice is not because we attempt to count individual electrons going through a wire, as it would be far too many to count!
Rather, it is because because there are two crazy quantum mechanical effects that give us macroscopic measures that are directly related to the electron charge. www.nist.gov/si-redefinition/ampere/ampere-quantum-metrology-triangle by the NIST explains that the two effects are:
- quantum Hall effect, which has discrete resistances of type:for integer values of .
- Josephson effect, used in the Josephson voltage standard. With the Inverse AC Josephson effect we are able to produce:per Josephson junction. This is about 2 microvolt / GHz, where GHz is a practical input frequency. Video "The evolution of voltage metrology to the latest generation of JVSs by Alain Rüfenacht" mentions that a typical operating frequency is 20 GHz.Therefore to attain a good 10 V, we need something in the order of a million Josephson junctions.But this is possible to implement in a single chip with existing micro fabrication techniques, and is exactly what the Josephson voltage standard does!
Those effect work because they also involve dividing by the Planck constant, the fundamental constant of quantum mechanics, which is also tiny, and thus brings values into a much more measurable order of size.
YouTube channels that just go over Stack Exchange questions Updated 2025-01-10 +Created 1970-01-01
Some people have been creating YouTube channels that just post and go over a large number of Stack Exchange questions, some of them with a quick random intro video. Perfectly legal due to CC BY-SA but really weird stuff!
- Roel Van de Paar www.youtube.com/@RoelVandePaar. This one seems to be the OG. As of June 2024 it had 2M videos (!), 161K subscribers and only 47M views. youtube.fandom.com/wiki/Roel_Van_de_Paar mentions "he has the highest number of uploads of any YouTube channel". Interestingly at www.linkedin.com/in/roelvandepaar/?originalSubdomain=au he says he is a test engineer at MariaDB.

rbrunner7:It's all quite strange. Never mind the 90s design, people built good websites already back then with the tools at hand, but even their "About" isn't very clear. If you need 5 minutes to be reasonably sure what it is all about they are still doing it wrong.

A non-tool-assisted speedrun.
Ciro Santilli views humans as biological robots, and therefore RTA videos can be thought of as probabilistic TAS with human achievable reflex constraints.
This aspect is especially highlighted in "speed run record evolution videos", which can be quite fun, e.g. www.youtube.com/watch?v=pmS9e7kzgS4 Ocarina of Time - World Record History and Progression (Any% Speedrun, 1990s-2017) by retro (2017)
From a similar point of view, Ciro also sometimes watches/learns a bit about competitive PvP games from a "could a computer play this better than a human" point of view.
Ciro also likes to watch commented manual speedruns of games as a way of experiencing the game at a high level without spending too much time on it, often from Games Done Quick. Their format is good because it generally showcases one player focusing more on the gameplay, and three couch commentators to give context, that's a good setup.
