History

After the death of Anko Itosu in 1915, one of Itosu's most senior students, Choshin Chibana, wanted to continue to teach the Shorin-ryū style of karate he learned from his instructor. Chibana named his system Shorin-ryū, but using the Chinese characters for "small" (小[1]) and "forest" (林[2]). Chibana lineage schools are commonly referred to as "kobayashi," but this is technically incorrect, as Chibana never used this term to refer to his karate. It was meant to be “Shorin” as tribute to the Shaolin Temple. (Shorin is the Japanese and Okinawan pronunciation of Shaolin). However, he believed strongly that Shorin-ryu was largely Okinawan and purposely modified the first character from the Chinese "Shao/Sho" so it would retain its originality. As other schools later adopted the name "Shorin-ryū," the term "kobayashi" was probably added to describe which exact characters were used to write the term "Shorin," but was never meant to be the official name of the style.

In 1920, Chibana opened his first dojo in the Torihori district of Shuri. Spellings such as "Tottoribori" or "Tottori-cho" are erroneous and incorrect. The old name of Torihori was Tunjumui, so it is unknown where these erroneous names originated. He later taught in other parts of Shuri such as Gibo and Yamakawa, and in Naha at Kumoji and Asato, with the main Chibana dojo being in Yamakawa.[3][4]

Chibana taught this style of Shorin-ryū until his death in 1969. Each of his top students went on to create his own branch of Shorin-ryū: Nakama Chozo created Shubokan, Yuchoku Higa created Kyudokan, Katsuya Miyahira created Shidō-kan, Isamu Arakaki created Shorin-ryu Kodokan, Shūgorō Nakazato created Shorinkan and Joki Uema created Shubukan.[5]

About the name

"... now the Japanese call it 'kobayashi style' but that is incorrect - but that is all right because only people who do not know Okinawan karate will call it by that name. Since they do not know you must gently remind them or the Okinawan people will laugh at their ignorance. After all, it is funny, many foreign people call it kobayashi shorin-ryu (小林小林流)- that is just like saying shorin shorin-ryu. It doesn't make much sense ..." [6][7]

The kanji are never written as 小林小林流 (kobayashi shorin-ryu) but always as 小林流 (shorin-ryu). The term Kobayashi Shorin-ryu is only used in the west and only by certain branches of Shorin-ryu. The Japanese reader of the kanji 小林流 automatically knows it is not Matsubayashi-ryu 松林流 because the kanji are different.

gollark: <@151391317740486657> Do you know what "unsupported" means? PotatOS is not designed to be used this way.
gollark: Specifically, 22 bytes for the private key and 21 for the public key on ccecc.py and 25 and 32 on the actual ingame one.
gollark: <@!206233133228490752> Sorry to bother you, but keypairs generated by `ccecc.py` and the ECC library in use in potatOS appear to have different-length private and public keys, which is a problem.EDIT: okay, apparently it's because I've been accidentally using a *different* ECC thing from SMT or something, and it has these parameters instead:```---- Elliptic Curve Arithmetic---- About the Curve Itself-- Field Size: 192 bits-- Field Modulus (p): 65533 * 2^176 + 3-- Equation: x^2 + y^2 = 1 + 108 * x^2 * y^2-- Parameters: Edwards Curve with c = 1, and d = 108-- Curve Order (n): 4 * 1569203598118192102418711808268118358122924911136798015831-- Cofactor (h): 4-- Generator Order (q): 1569203598118192102418711808268118358122924911136798015831---- About the Curve's Security-- Current best attack security: 94.822 bits (Pollard's Rho)-- Rho Security: log2(0.884 * sqrt(q)) = 94.822-- Transfer Security? Yes: p ~= q; k > 20-- Field Discriminant Security? Yes: t = 67602300638727286331433024168; s = 2^2; |D| = 5134296629560551493299993292204775496868940529592107064435 > 2^100-- Rigidity? A little, the parameters are somewhat small.-- XZ/YZ Ladder Security? No: Single coordinate ladders are insecure, so they can't be used.-- Small Subgroup Security? Yes: Secret keys are calculated modulo 4q.-- Invalid Curve Security? Yes: Any point to be multiplied is checked beforehand.-- Invalid Curve Twist Security? No: The curve is not protected against single coordinate ladder attacks, so don't use them.-- Completeness? Yes: The curve is an Edwards Curve with non-square d and square a, so the curve is complete.-- Indistinguishability? No: The curve does not support indistinguishability maps.```so I might just have to ship *two* versions to keep compatibility with old signatures.
gollark: > 2. precompilation to lua bytecode and compressionThis was considered, but the furthest I went was having some programs compressed on disk.
gollark: > 1. multiple layers of sandboxing (a "system" layer that implements a few things, a "features" layer that implements most of potatOS's inter-sandboxing API and some features, a "process manager" layer which has inter-process separation and ways for processes to communicate, and a "BIOS" layer that implements features like PotatoBIOS)Seems impractical, although it probably *could* fix a lot of problems
