As a native Korean speaker who has used this language for more than two good decades with Koreans, I'd count this as the primary reason why I love hanging out with English and Chinese speakers these days.
The language barrier between two Korean strangers (irony) is much thicker than when I talk to a passerby in English or Chinese asking for directions.
Being a 빠른 can put you in a slightly sticky situation, especially when combined with the strict hierarchy rules regarding honorifics (존댓말).
Typically, throughout middle school to university days, a South Korean individual is expected to use the honorific version of the language when speaking to someone older. This version involves a completely different set of vocabulary and grammar, used to show "respect to others" and sound "polite," effectively preventing one from being casual with others. Whereas a 빠른 is allowed to befriend people one year above their age and gets to use "반말" (the casual version of the language) with those peers.
A social complication can arise when two groups with a monotonic increase in age meet. Say, friend group A comprises a regular 95 and a 빠른 95. They became friends in high school and talk casually. Then there's group B, which consists of a regular 95 and a 빠른 96, who also became friends in high school. Now, when groups A and B start hanging out together at university, the 빠른 95 has to decide whether to use honorific or casual speech with the regular 95 and the 빠른 96.
The ones stuck in the middle, in this case the 빠른95, gets called "족보 브레이커", which roughly translates to "pedigree breaker".
This article does not address another layer that makes the Korean age system complicated: the "빠른" system. It refers to people born in January or February who, due to the school cutoff being in March, often enter school a year early and socially identify with those born in the previous calendar year.
For example, if I'm "빠른95", which indicates that I was born in 1995 between January and the end of February, I get to befriend and hang out with the ones born in 1994.
(Please note that Koreans typically make friends within the same narrow age band.)
Without Kanji, it severely degrades readability. One has to reconstruct the word from syllables, which introduces another layer of cognitive load.
In Korean, it works similarly as well though, most people nowadays are quite used to not incorporating Hanja in sentences over multiple decades, to the point where it would be impractical to mingle Hanja in Korean.
How does turning off TC keep your car from killing you in the rain? just out of curiosity. In my experience, TC has been very helpful, as it means I don't have to worry about feathering the gas pedal in heavy rain.
The Quake series' source code is a must-read if you wish to learn how to create a fast-paced multiplayer game from scratch. Obviously, you can use Mirror or other 3rd-party middleware nowadays, but reading it gave me multiple layers of knowledge regarding the netcode aspect of a game.
