Abing by Ciro Santilli 40 Updated 2025-07-16
Once Ciro Santilli played Suwu herding sheep while his mother in law was around, and she quickly pointed out:
Suwu by Abing!
He's very popular!
And also a composer, e.g. he composed Reflections of the Moon on Erquan.
Korean drama by Ciro Santilli 40 Updated 2025-07-16

North Korea keeps itself cut off from the internet and sends these highly trained specialists to do work in China, Southeast Asia and elsewhere to avoid international sanctions imposed on the country for its nuclear weapons program. The specialists usually live together in dormitory apartments, where they are instructed to spy on each other. Their North Korean minders look for signs of disloyalty - like watching K-dramas.
K-drama, the ultimate symbol of resistance. Epic.
British pragmatism by Ciro Santilli 40 Updated 2026-03-05
The British are very pragmatic. This has good and bad effects.
For example, a good effect is that many things work pretty well, such as the government. This also helped industry develop.
A bad effect is that they sometimes settle on local minima forever. Examples:
  • written Constitution? Who needs a written constitution!
  • as of 2020, they are still using imperial units in everyday life, rather than International System of Units, which was setup by the French, who are much more idealistic, and can therefore can break from such insanity more often.
  • the persistence of the insane system of colleges of the University of Oxford
  • the incredibly late date of the decimal day in 1971, and that was partly due to the advent of the computer. That one was too much, even for the Brits, or maybe it helped that the greedy financiers were involved
  • the British train system as of the 2010's, which is completely not unified, each part operated by a different company with different standards. Private and public unification efforts are ongoing, Trainline being one of the best/only private buy from any line unification approaches.
  • Church of England priests can marry, which reduces the proportion of pedophiles. Also women were accepted starting in the 1970's in certain dioceses (non uniform rules as usual, typical of English pragmatism), including for bishop
If it ain't totally broken, just let it continue forever! See also: Section "History of the University of Oxford".
Uranus by Ciro Santilli 40 Updated 2025-07-16
The first planet not known since antiquity.
Encryption algorithms that run on classical computers that are expected to be resistant to quantum computers.
This is notably not the case of the dominant 2020 algorithms, RSA and elliptic curve cryptography, which are provably broken by Grover's algorithm.
Post-quantum cryptography is the very first quantum computing thing at which people have to put money into.
The reason is that attackers would be able to store captured ciphertext, and then retroactively break them once and if quantum computing power becomes available in the future.
There isn't a shade of a doubt that intelligence agencies are actively doing this as of 2020. They must have a database of how interesting a given source is, and then store as much as they can given some ammount of storage budget they have available.
A good way to explain this to quantum computing skeptics is to ask them:
If I told you there is a 5% chance that I will be able to decrypt everything you write online starting today in 10 years. Would you give me a dollar to reduce that chance to 0.5%?
Post-quantum cryptography is simply not a choice. It must be done now. Even if the risk is low, the cost would be way too great.
Saint Peter by Ciro Santilli 40 Updated 2025-07-16
Brother of andrew the Apostle, called by Jesus in fishers of men. Born Simon, but Jesus renamed him to Peter, thus the weird "Simon called Peter" way he is referred to as in some versions of the Bible.
Great doubt by Ciro Santilli 40 Updated 2025-07-16
The type of feeling of confusion and distrut for your sense that some Koans attempt to instill.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
