It says in the description that this is a version with minimal changes that exists because uBlock is not available in China. It looks like the source is located here: https://codeberg.org/lanticy/cBlock

I wouldn’t use it if you have the ability to use the original uBlock, but if you have no other choice, this looks plausable.

Hmm… “Sometimes Snow <whatever>”?

I say it should be illegal to incorporate the word “snow” in the names of things that are not white.

I must inform you, the bug is very much black under the mask.

There is a category of Russian memes known as “волчьи мемы” (literally “wolf’s memes”) where you have a picture of a wolf, often distorted, put some cliche edgy text on it, but swap some words to make it into something hilarious.

If someone didn’t learn enough trigonometry in school:

1+tan²c = cos²c/cos²c + sin²c/cos²c = (cos²c + sin²c)/cos²c = 1/cos²c;

sqrt(1/cos²c) = |sec c|

The divisability rule for 7 is that the difference of doubled last digit of a number and the remaining part of that number is divisible by 7.

E.g. 299’999 → 29’999 - 18 = 29’981 → 2’998 - 2 = 2’996 → 299 - 12 = 287 → 28 - 14 = 14 → 14 mod 7 = 0.

It’s a very nasty divisibility rule. The one for 13 works in the same way, but instead of multiplying by 2, you multiply by 4. There are actually a couple of well-known rules for that, but these are the easiest to remember IMO.
