Reply to comment by Educational-Eye5076 in ELI5: what actually is keto, acidosis and keto-acidosis..? by Educational-Eye5076

Don't confuse diet-induced ketosis (which simply results from a very low-carbohydrate diet) with ketoacidosis, which is a serious medical condition. They are totally different things that involve some of the same mechanisms even though they sound similar.

For normal, healthy people, a ketogenic diet (one which induces ketosis) is not harmful. More specifically, it does not cause ketoacidosis.

Reply to ELI5: what exactly is data? What is information? Do they represent anything physical/take up space? by Azooz321

I haven't seen anyone point out the obvious so here goes .

You are referring to data stores specifically on a computer or device. Others did a good job answering that question so I won't rehash.

What I want to point out is your use of the word data. Data is simply a collection of information. It can be on a computer, on paper. Or in your mind. It does take up both physical and virtual space. It can be word on paper, 1s and 0s on a machine, or neurons in your brain.

What takes up physical space is the symbols we use to represent data. "John Doe lives on 123 Anystreet USA" is the physical characters that make up the set of data. By "virtual space" I am referring to the implications that come with the data. With that information, you know know how to get to John Does house, even though the data doesn't explicitly spell it out.

Tldr: data is the physical representation of a symbol, thought, or idea that occupies space in the physical world and carries certain implications for meaning.

As some lovely young ladies on a TLC show informed me,

“Diet soda cancels out the sugars [of the foods you eat].”

Like they literally believed it would just erase any sugars you had consumed that day from your body, like a miracle potion. You can find the clip by searching I’m sure. The American South is a wild place.

Reply to comment by AtHomeInTheUniverse in ELI5: In recent years, new formats like webp and jfif have started popping up. However, if I rename them to gif or jpeg, they still work. How can it be that renaming the extension doesn't ruin the image format? Why do they even exist then? by Luthemplaer

Fun fact: I've encountered jpeg files mis-labeled as ".gif" and vice-versa. A lot of software has no trouble with this at all, since it looks at the magic number. Your web browser for example.

Reply to comment by Kancelas in eli5: why do birds bop their heads when they walk? by Capitan_kermit86

This is correct. I used to work on the design of cameras for an aviation company and one of the contacts we were awarded was to design a new low friction mechanism gimbal for small camera systems.

As you would imagine, in aviation you're heavily space and weight constrained so it meant lots of careful design to fit the allocated constraints.

You can imagine my surprise when I learned that the government wanted to sign an exclusive manufacturing contract when they learned that we were producing this commercial for airlines. Help I've gotten myself so deep into this compulsive lie I don't know how to stop. The governmeny turned around and ended up using it in most regent design for birds and due to the lowered friction it resulted in a more prominent head bobbing.

So yeah, pretty spot on.
