The first time Ciro Santilli Googled this was when trying to repair his cell phone.
2019 cell phones are glued together with adhesive, which makes them impossible to repair them unless you have a heat gun, spend hours and hours learning and planning, and accept the risk of breaking the screen
If you take a phone less than 300 dollars to a repair shop in the first world, they will say: I've never repaired this crap, and likely for the price of the repair you should just buy a new one, and so to the trash goes the old one, polluting the planet, and in comes a new one, enriching the manufacturer further.
EverybodyWiki Updated +Created
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.

OurBigBook.com Updated +Created
The website is the reference instance of OurBigBook Web, which is part of the OurBigBook Project, the other main part of the project are software that users can run locally to publish their content such as the OurBigBook CLI.
This page contains further information about the project's rationale, motivation and planning.

ROW_NUMBER Updated +Created
sqlite3 ':memory:'  'WITH t (i) AS (VALUES (-1), (-1), (-2)) SELECT *, row_number() over () FROM t'
Possible output:
-1|1
-1|2
-2|3
Gives them unique IDs.
With a partition by:
sqlite3 ':memory:'  'WITH t (i) AS (VALUES (-1), (-1), (-2)) SELECT *, row_number() over ( partition by i ) FROM t'
possible output:
-2|1
-1|1
-1|2

Ampere in the 2019 redefinition of the SI base units Updated +Created
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:
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 +Created
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!

Phaser.js Updated +Created
Likely the best JavaScript 2D game engine as of 2023.Uses Matter.js as a physics engine if enabled. There's also an alternative (in-house?) "arcade" engine: photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.ArcadePhysics.html but it appears to be simpler/less robust (but also possibly faster).
The examples are present under:
git clone https://github.com/photonstorm/phaser3-examples
but note that that repo is huge, about 4.5 GiB on local disk, as is has tons of assets.
The demos also include a Monaco-editor based sandbox mode where you can edit code directly on the web and see the game update which is a really sweet addition.
Photoelectric effect Updated +Created
No matter how hight the wave intensity, if it the frequency is small, no photons are removed from the material.
This is different from classic waves where energy is proportional to intensity, and coherent with the existence of photons and the Planck-Einstein relation.
