YouTube channels that just go over Stack Exchange questions Updated 2025-01-03 +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.
- Peter Schneider www.youtube.com/@peterschneiderQandA e.g. www.youtube.com/watch?v=GBQhrKRpUdI "How to put a newline special character into a file using the echo command and redirection operator?" from unix.stackexchange.com/questions/191694/how-to-put-a-newline-special-character-into-a-file-using-the-echo-command-and-re)Stackexchange
- Sophia Wagner www.youtube.com/@SophiaWagnerQandA. As of June 2024 it had 14k videos and only 88k views, so she made 88 bucks on it.
- E.g. www.youtube.com/watch?v=elIlkJneVBI "Vertically stack multiple images using ImageMagick" goes over superuser.com/questions/290656/vertically-stack-multiple-images-using-imagemagick
- www.youtube.com/@LukeChaffeyTechInfo Luke Chaffey, an Indian-American dude, e.g. www.youtube.com/watch?v=wmx6mN_G83s "Do Boost Geometry nearest queries always sort results ordered by smallest distance first?"
- www.youtube.com/@pythonoracle The Python Oracle. Speech synthesis, with different accents. Cute!
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.

-TrustyDwarf-:Anyone mind to explain wtf this ugly piece of webpage reminding me of geocities from the 90s is about? I'd read it myself but I can't because it already gave me eye cancer.

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.

Static case of Maxwell's law for electricity only.
Is implied by Gauss' law if Maxwell's equations: physics.stackexchange.com/questions/44418/are-the-maxwells-equations-enough-to-derive-the-law-of-coulomb
The "static" part is important: if this law were true for moving charges, we would be able to transmit information instantly at infinite distances. This is basically where the idea of field comes in.
The Taylor series expansion is the most direct definition of the expontial as it obviously satisfies the exponential function differential equation:
- the first constant term dies
- each other term gets converted to the one before
- because we have infinite many terms, we get what we started with!

This contains various outputs that seem trivially spendable in a made up of two non-zero constants, e.g.:Or are we missing something? The values are quite small and wouldn't be worth it the miner fees most likely. But is there a fundamental reason why this couldn't be spent by a non-standard miner?

},Compared to Waring's problem, this is potentially much harder, as we can go infinitely negative in our attempts, there isn't a bound on how many tries we can have for each number.
In other words, it is unlikely to have a Conjecture reduction to a halting problem.

Source. It should be illegal to give someone money to advertise your product.
We should just use tags and upvote-based algorithms.
Advertisement is a form of brainwashing.
TODO find Sergey Brin quote bout advertising being a form of perverting search engine ranking neutrality. In other words, there are neutral metrics to what people find good, like links and upvotes. And then advertising is a way to pervert that to someone's profit.
Sometimes Ciro Santilli thinks advertising should be on-subscription only, but that is too restrictive, e.g. imagine the local business owner who wears a t-shirt of their business.

Linear combination of a Dirichlet boundary condition and Neumann boundary condition at each point of the boundary.
Examples:
- heat equation when metal plaque is immersed in a large external environment of fixed temperature.In this case, the normal derivative at the boundary is proportional to the difference between the temperature of the boundary and the fixed temperature of the external environment.The result as time tends to infinity is that the temperature of the plaque tends to that of the environment.Shown a solved example in the FreeFem tutorial: doc.freefem.org/tutorials/thermalConduction.html (github.com/FreeFem/FreeFem-doc/blob/1d5996d8b891fd553fd318321249c2c30f693fc3/source/tutorials/thermalConduction.rst)
