They say you learn something new every day. Let's see if that statement is true!

ITT post something new you learned today. Trivia knowledge is more than welcome.

They weren't really to symbolise things but their traits would be compared to biblical references, so each entry ends with kind of a biblical rant. The Pelican wasn't really Jesus but if a young pelican stuck the face of it's parent the parent was said to then kill it and after three days the mother would tear open her chest and pours blood over it which would resurrect it, the writer then compares this to what Jesus did when he resurrected in three days.

Chinese Archery
>> No. 33700 [Edit]
The bows in both the videos are actually Manchu bows not Chinese persay but the people using them are dressed in an older style and have top nots not pigtails. The Manchu bows have those long siyahs to help draw them(they are meant to be quite powerful), the bow in your image is more like a Chinese bow.

If you were to try to access the cannibalism in China Wikipedia page you would be disappointed because it's been blocked due to copyright. I guess I did not learn this today but I tried a while ago to view this page and then tried again today and it's still blocked, something suspicious is going on here. I guess that is what I learnt.
>> No. 33710 [Edit]
You can access older versions of the article from "view history" and you can also see the discussion as to why the article was made inaccessible. I have read a couple of subjects related to the subject and while I'm not an expert, some things are definitely misinterpreted. I know that during times of war as far back as the Han Dynasty, soldiers cannibalised in times of famine. There was also a form of torture or execution called slow slicing which involves methodical removal of parts of the body but I don't remember elements of cannibalism being involved. Lastly, there was the mellified man, which was a dubious medical practice adopted from the near east.

Certain train departing jingles in Japan are operated by train crew.
Thought that it was completely automated, or operated by some sort of station master or signalman. Now that I think it about, it does make sense to make sure the train is on schedule.
>> No. 33896 [Edit]
I wonder if it's also done manually for safety reasons, similar to their "point and call" system.

Nissan is owned by Renault.

Did that deal actually go through? I thought one of the rumored reasons why the Ghosn kerfuffle happened was that some Japanese higher-ups supposedly didn't like Nissan being bought out by some gaijin company.
>> No. 33982 [Edit]
I head that Nissan was owned by Renault but that the issue with Ghoson was that he was trying to merge Nissan with Renault.

The 2 tone chime that is often heard in train stations throughout Japan is meant to guide visually impaired people to the ticket barriers.

In the following video, listen closely and notice how the chime gets louder as the videographer nears the stairs. Actually, you can see the speaker hanging from the ceiling, right in front the stairs at a low height.
>> No. 34100 [Edit]
That's a very clever and low-cost solution!
>> No. 34130 [Edit]
I think so. To make sure the barriers/doors are closed and secured. As per their "point an call" safety method, particularly in the shinkansen , the calls you'll almost always hear when departing:

出発ヨシ!shiyuppatsu yoshi! "Departure OK!"
安全ヨシ! anzen yoshi! "Safety OK!"

The melodies in this case help both crew and passengers realizing that the train is about to depart. There's a great video that explores this topic a bit more in depth on YT:

How is the arc damage handled? I imagine pantographs are trivial to replace but how do they maintain the millions of kilometers of traction? Aren't the wires getting plasma torched crazy fast with heavy traffic like this?
>> No. 34262 [Edit]
File 158396753557.webm - (6.15MB , 大宮駅arc_and__asmr.webm )
The arcs don't last long enough to super heat the wire causing it to melt or something, as in the video below. The same way you're not burned instantly by an electrical shock, or how some people survive lightning strikes.

In a paper published by JR East in 2017, it says the OCL on the Joetsu Shinkansen "are nearing replacement after 30 years since the start of operations". So that should give an idea of how long they may last.
JR EAST Technical Review No.36-2017 - Simplification of Structure of Shinkansen Overhead Contact Lines

In a another publication, this time from France, it says HSR catenary last up to 50 years.

As for the pantographs, they have quite a thick layer of graphite and usually last between 9 months and a year, and are replaced as per routine maintenance. Said graphite is the cause of that dark dirtiness on top of the carriages, particularly noticeable on the white N700.

The system of counting to 60s, like in seconds, minutes, comes from the Babylonians.
>> No. 34354 [Edit]
Supposedly they liked 60 because it has a lot of factors:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Not bad for a pretty compact number – out of the numbers between 1 to 100 that have the most factors (12 factors), 60 is the smallest.

However navigating in jap-only websites is still a little difficult and i fear i might have missed something good.I have abt 40 routes till now (scenarios folder abt 4gb) mostly by following links in that huge playlist of SF's Rail Depot channel on yt.
Do you know any other sources/routes/stock? preferably of high quality/well made?

I started fiddling around with a C64 emulator and writing a few short programs in it, and in the process learned to use every legal instruction in 6502 assembly.

I also learned that I would probably be making a lot more money today if someone had shown me how to get started with programming on my family's C64 when I was a kid. All I ever knew about using it came from a single sheet of paper that described how to load and run games.

It's kind of a shame that I'm too reclusive and socially inept to ever have children myself. If nothing else, I would take very good care of their education.

Speaking of buggy software, I found out that driving a Toyota car is a good way of dying a death caused by shoddy programming:
>Other egregious deviations from standard practice were the number of global variables in the system. The academic standard is zero. Toyota had more than 10,000 global variables.
>When NASA software engineers evaluated parts of Toyota’s source code during their NHTSA contracted review in 2010, they checked 35 of the MISRA-C rules against the parts of the Toyota source to which they had access and found 7,134 violations. Barr checked the source code against MISRA’s 2004 edition and found 81,514 violations.

Mind you, this just what they found in the electronics of a normal car built 15 years ago. Nowadays people entrust self-driving cars with their lives.

>I also learned that I would probably be making a lot more money today if someone had shown me how to get started with programming on my family's C64 when I was a kid.

I see where you're coming from, but as someone who did pick up programming as a kid, I can tell you it's not just about when you start. You have to know people when you're young. I'm not saying you need to be as connected as Bill Gates was in his childhood, but you'll just need to know someone who can give you a chance to shine. So either your parents have to know someone, or your parents teach you the necessary life skills to go out there and build those early connections on your own (you'd be surprised how few parents actually do this for their kids; I know mine didn't).

I learned there are formulas for trig functions whose arguments are different inverse trig functions. I feel like a jackass for not knowing sooner.

I remember the controversy about unintended acceleration in Toyotas, but I assumed the floor mats were the culprit since it was out of the news cycle after they issued a recall. I refuse to own cars with drive-by-wire because the throttle response is always wildly inconsistent compared to a cable throttle. It'll be interesting to see how a self-driving car will behave after 15-20 years of salt exposure on its internals considering the glitches they already have from the factory.

This guy:

>Josiah Willard Gibbs (February 11, 1839 – April 28, 1903) was an American scientist who made significant theoretical contributions to physics, chemistry, and mathematics. His work on the applications of thermodynamics was instrumental in transforming physical chemistry into a rigorous inductive science. Together with James Clerk Maxwell and Ludwig Boltzmann, he created statistical mechanics (a term that he coined), explaining the laws of thermodynamics as consequences of the statistical properties of ensembles of the possible states of a physical system composed of many particles. Gibbs also worked on the application of Maxwell's equations to problems in physical optics. As a mathematician, he invented modern vector calculus (independently of the British scientist Oliver Heaviside, who carried out similar work during the same period).

Very interesting, anon. Also very weird how his mentor was a fat-ish old man and lifted such heavy weights.

The best body for lifting heavy things is stocky. Large gut and massive, muscular arms. The typical bodybuilder thing isn't actually that functional and mostly for show.
