  • Wikipedia says:

    The mitochondrion is popularly nicknamed the “powerhouse of the cell”, a phrase popularized by Philip Siekevitz in a 1957 Scientific American article of the same name.[4]

    But know your meme attributes its meme status to this tumblr post from 2013:

    screenshot of text: "what i learned from school 1. im a fucking piece of shit 2. everybody else is also a fucking piece of shit 3. mitochondria is the powerhouse of the cell"

    Contrary to comments in many places like this reddit thread from 2018, I suspect the phrase wasn’t actually used in many textbooks or very commonly known prior to that tumblr post.

    (If you search on Google Books you can find numerous textbooks using the phrase. Range-based search on Google Books appears to be broken so I’m not sure, but all the ones I checked were published well after 2013.)

    were you careful to be sure to get the parts that have the key’s name and email address?

    It should be if there is chunks missing its unusable. At least thats my thinking, since gpg is usually a binary and ascii armor makes it human readable. As long as a person cannot guess the blacked out parts, there shouldnt be any data.

    you are mistaken. A PGP key is a binary structure which includes the metadata. PGP’s “ascii-armor” means base64-encoding that binary structure (and putting the BEGIN and END header lines around it). One can decode fragments of a base64-encoded string without having the whole thing. To confirm this, you can use a tool like xxd (or hexdump) - try pasting half of your ascii-armored key in to base64 -d | xxd (and hit enter and ctrl-D to terminate the input) and you will see the binary structure as hex and ascii - including the key metadata. i think either half will do, as PGP keys typically have their metadata in there at least twice.
