  If you want to calculate the cipher on paper everything that works on binary will be a huge overhead and basically require you to write stuff down for the calculations. So you need to burn sheets of paper for every en/decryption. So no XOR or anything.

  I would go for a stream-caesar-cipher. Find a mathematical formula that you can calculate in your head and that gives you a numbers between 1-35 (or something similar depending on how many different characters you need). The formula must be pseudo random so f(x)=5, f(x+1)=1, f(x+2)=28, … and not loop for a looooong time. Calculate a new value FOR EVERY LETTER OF YOUR TEXT!!! and use that as your Caesar cipher for that letter only (x is the position of the character in the text)

  You need to keep track which letter in your cipher text was encoded with which x (write the x of the first letter of each page down) and keep the formula a secret. Never ever under any circumstance reuse an x. So you need to keep x going for every page/message and can’t restart at 1 each time.

  If x becomes to large and the calculations to complicated, its better to change the formula than to restart x. Never ever ever ever reuse the same cipher because then you get all the drawbacks of Caesar ciphers (probability of letters, length of words (position of the space character) etc).

  It becomes a whole different thing when you yourself are a creator of any kind. Sure you can retorrent TBs of movies. But you can’t retake that video from 3 years ago. I have about 2 TB of photos I took. I classify that as media.

  Interesting, I’ll look into this.

• ⁨Comment⁩ on ⁨Does the southern hemisphere get colder farther from the pole? Why?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Europe is a lot warmer than it should be because of the gulf stream that brings warm water from the equator. If you look at the same latitute in north america/Asia the climate will be a lot cooler there.

  South america on the other hand is cooler than it should be simply by latitude because of the humbold current and the Antarctic ocean.

  So you are comparing the warmest point with the coldest one at the same latitude (mirrored on the southern hemisphere)

  Not really. There was a lawsuit that claimed they contain no tuna. A lab found no tuna DNA, a different lab did. The lawsuit shifted to “does not contain only this type if tuna”.

  Also highly processed food (especially after it was cooked) does not contain any DNA that is identifiable.

  What actually is the “problem”? I see articles talking about trolls and anti-woke but I dont find anything why people are mad.

  They made a character younger… shouldn’t that be what trolls want? Dont they normally complain when female characters are to old?

  It consumes the resource of “purified, available water” which is consumed as it is no longer purified or unavailable (if evaporated). The same way nothing ever “consumes” energy, it just makes it unusable.
