Kerckhoffs's principle by Ciro Santilli 37 Updated 2025-07-16
Basically the opposite of security through obscurity, though slightly more focused on cryptography.
Lin Chong scene by Ciro Santilli 37 Updated 2025-07-16
Lance instructor of the 800,000 Imperial Guards (八十万禁军枪棒教头). TODO understand the "枪棒" part: zhidao.baidu.com/question/206659649.html.
The adopted son of Gao Qiu wanted to fuck his wife, and because of this they frame him of planning to take revenge by killing Go Qiu, even though Lin Chong had decided not to take revenge to avoid harming his wife further.
They just keep trying to kill him, until at one point he just gives up and becomes a fugitive.
His story is well told in The Water Margin.
Usually called by others as 林教头 (lin jiaotou, literally Head Instructor Lin, but usually translated as just Instructor Lin).

Stolen traight from www.silkqin.com/10ideo.htm on silkqin.com:
Wind in the pines and a babbling brook are nature's melody. A qin was brought along, but there is no need to play it
The The Gateless Barrier vibe and Chinese naturalism is just awesome.
Li sao (guqin song) by Ciro Santilli 37 Updated 2025-07-16
www.facebook.com/131402556881886/posts/655763214445815/ gives an origin:
Li Sao was composed by Cheng Kangshi in late Tang dynasty based on the poem Li Sao, authored by Qu Yuan (340-278 BC) in the Warring States period of ancient China.
The silkqin.com entry: www.silkqin.com/04qart/07sqmp/57ls.htm does not mention this however.

A Baidu Baike page: baike.baidu.hk/item/層層水瀾/12386243 mentions that the score was published in 1970 by Tao Yimo (陶一陌) in a eponymous score book.

This piece is a reference to Dragon boats from the Dragon Boat Festival.
The explosive moments presumably represent the intense rowing action of a dragon boat race competition.

Unclear legality:
Tokyo by Ciro Santilli 37 Updated 2025-07-16
Literally: "capital of the East". Note that the Chinese term 东京 (dong1 jing1) is highly ambiguous in historical contexts, as many places throughout history have been known as "the capital of the East".Of of those other places is the Kaifeng, which is the Capital in Water Margin and in real life during the Song dynasty. The novel is also likely highly popular in Japan apparently as well BTW, e.g. it merited a well funded adaptation: The Water Margin.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
