As an American with minimal cultural context -- your video is BRILLIANT and your level of snark is hilarious and impressive!

What does 666 mean and how do you know what the mark is in revalation? Thats what I want to know more than anything else.

@matj12 9 ай бұрын

How does the quote at the end hint to that I can find any interpretation I want? Or, if I misunderstood it, which quote is it?

30:14 Ah Hah! The label "Error correction MODULES" is shown on the video. Even the [CC] thought you were saying "models" this whole time. I didn't understand why a single square was (also) called a model. How about supplying your own subtitles with the video, directly from the script? It could really help. BTW, in English "Galois" is pronounced the way an English-speaking person would repeat back the way Gaalois (or some other native French speaker) would say it. So it's gal-WAH. More rigorously, using IPA it's /ɡælˈwɑː/.

OMG, just heard it, you right. I will add subtitles, it's confusing. I was thinking first about replacing this word with "squares", but in this case there is no way to differentiate between them. Like: "QR code is a big square that is made of small squares and have medium squares to orient big square the right way" just does not sound right.

This video is pretty good! It is a shame that conspiracy theories poison the brains of everyone everywhere on the internet, and misinformation spreads like wildfire. I'm grateful for this cultural insight, and the education!

пысмылла, машшалла, яраткан ялгыз алла, кюаркоды - баракат иншалла, да светится КЮ твоё, да приидет АР твоё, иже еси на пропагнадистских вакцинах, да развеется страх, да сгинет толпа, да откроются глаза, да поймётся безопасность сквозь вечное напоминание об мнимой опасности, аминь.

Clicked for the title, stayed for the QR code explanation, left disappointed for the "... and why Russians are afraid of them" part...

@jursamaj 11 ай бұрын

Eh. Nice explanation, but I could do without all the christian mythology.

@suyunbek1399 8 ай бұрын

and how exactly would you manage that? christian mythology is essential in understanding all the intricacies. if you consider them excessive, you better rethink your way of thinking.
