Hab so einen Neon-Unnützes-Wissen-Kalender, und dieses "Fakt" ist typisch: Viel wahres dabei, dennoch falsch/irreführend/ungenau.

This also means that there is an "easy" divisibility test for _any_ number, assuming you can transform a number into an arbitrary base:

Is 236487234543 divisible by 13?
No, because 0yB635D2A727's cross sum (using the 0y prefix to denote base 14) is 0y4a (or 66 in decimal), which isn't divisible by 13.

Divisibility rules are weird in hexadecimal. For example, a number is divisible by 5 if its cross sum is divisible by 5. The same also works for 3 (like in decimal), and 0xf (15).

To check if a number is divisible by 17, just put it in base 16, reverse it, and do an alternating sum, e.g.:

21263712472 is divisible by 17, because:
1) it is 0x4f36a80d8
2) 8 - d + 0 - 8 + a - 6 + 3 - f + 4 is -17
3) -17 is divisible by 17.

Immer wenn ich "Johannes S." lese, muss ich an extra3 denken.

I doesn't speak very many, but I do the best, what I are.

Where did the practice of using configuration files named "Somethingfile" (first letter capital, ending in "file") start?

"i use linux as my operating system," i state proudly to the unkempt, bearded man. he swivels around in his desk chair with a devilish gleam in his eyes, ready to mansplain with extreme precision.
"actually," he says with a grin, "linux is just the kernel. you use GNU+linux."
i don't miss a beat and reply with a smirk, "i use alpine, a distro that doesn't include the GNU coreutils, or any other GNU code. it's linux, but it's not GNU+linux."

the smile quickly drops from the man's face. his body begins convulsing and he foams at the mouth as he drop to the floor with a sickly thud. as he writhes around he screams "I-IT WAS COMPILED WITH GCC! THAT MEANS IT'S STILL GNU!"
coolly, i reply "if windows was compiled with gcc, would that make it GNU?" i interrupt his response with "and work is being made on the kernel to make it more compiler-agnostic. even if you were correct, you won't be for long."

with a sickly wheeze, the last of the man's life is ejected from his body. he lies on the floor, cold and limp. i've womansplained him to death.

Ist es legal, einem Scammer eine gefälschte Ausweiskopie zu schicken?

When TV/film people explore the territory of interactive TV/film and ignore the established existence of video games its like a bunch of professional runners deciding to experiment with holding running races in the water, and then loudly exclaiming they are pioneering new "water running' techniques while ignoring the whole established concept of swimming.

if any one doesn't know how to make a psot on mastodon i made a tutorial :)
