No, most is still spinning disks. The cost to storage space is still in favor of hard disk drives. SSD is a more stable storage medium, and a lot of data centers are upgrading to that, But spinning disks still takes the cake

Reply to comment by newerdewey in eli5 why raspberries spoil so much easier than other commercially harvested berries? by newerdewey
Two reasons:
- It'd be significantly more difficult to do so, and more importantly:
- The torus isn't edible in raspberries. It won't kill you or anything, but it doesn't taste very good.

In networking, using data means using bandwidth (a fraction of the total network speed). It is similar to renting rooms in an apartment building. When you rent a room you are using space in the building. Since the life time of the building is finite using space in the building costs money. Similarly when you watch a video you are using a fraction of the total network bandwidth. The higher the resolution of the video the higher the fraction of the total network bandwidth is used. The longer you watch the higher the fraction when averaged over a month. And similar to a building network equipment life time is finite so using a fraction of the total bandwidth costs a similar fraction of the total network cost.

Reply to comment by sixfourtykilo in ELI5 How is drinking a diet soda different than drinking plain water when it comes to your health? by LucyLegBeard
It is, but people who drink 4 or more cups of coffee a day aren't less dehydrated than people who don't drink that much.

So there are physical and mathematical ties to the concept of information. This is called Information Theory . I'm sure someone with a Theoretical Physics degree that can explain it properly. Just wanted to point it out.

Also, it seems like the physical structure of a bat is less like a bag of fluid than that of a human being.

Giraffes have a special circulatory in their necks to combat this because their blood pressure is so high they would blow their own brains out if they bent down to the ground and didn't have it

The hydrostatic pressure differential is based on the height of the column. For something as short as a bat, the contribution of hydrostatic pressure to their blood pressure isn't very significant. I.e. whatever musculature is required to keep their circulation tracking appropriately is likely enough to compensate for the hydrostatic differential.

a good answer to an interesting question. Fine Eli5 experiences like that are hard to come by these days

There are 3 other replies, but I don't think any are really ELI5.
The answer needs a few parts:
> What exactly is keto?
Keto is short for ketosis, a change in how your body uses energy.
Your body uses building blocks for all kinds of things. Two of those building blocks are carbohydrates also called sugars, and hydrocarbons also called fats and oils. The body uses them for many purposes including using them to make energy. In chemistry the difference is fairly small, carbohydrates (sugars) contain Carbon, Hydrogen, and Oxygen, and hydrocarbons (fats/oils) contain Carbon and Hydrogen. The body is able to burn both of them for energy but it takes a slightly different chemical reaction.
Normally the body likes to use sugar (carbohydrates) found in food. If you don't eat enough carbohydrates, your body switches over to use fats and oils found in food. It takes several days of not eating carbohydrates before your body decides it needs to switch gears and get most of its energy from the fats and oils in food instead.
Normally when your body uses sugar it converts it into energy, water, and carbon dioxide.
When your body is in ketosis, the process of using fats and oils generates energy, water, and carbon dioxide, but the different chemical reaction also produces some acids called "ketones". That's where "keto" and "ketosis" get their names.
More on this in the third part.
> What is acidosis?
Acidosis is when there is too much acid in your blood.
There is an acid/base balance in your blood. Normally your blood has a pH of about 7.4. If your blood becomes too acidic it is called acidosis. If your blood becomes to basic it is called alkalosis. Acidosis is when your blood pH drops below about 7.35. Alkalosis is when your blood pH goes above 7.45.
Both acidosis and alkalosis are bad for your organs. If the blood is too acidic or too basic, your organs will start to fail and you will die.
> What is keto-acidosis?
It is acidosis (blood turning acidic) caused by ketosis (using fats and oils).
Burning fats and oils is a normal thing for your body, and it can usually handle it just fine. Normally your body can neutralize the acids and extract it into urine just fine. Sometimes, your body can't keep up. Diabetics are much more likely to both produce more ketones and also have more difficulty filtering them out.
If your body can't process the ketones out fast enough your blood becomes acidic.
When that happens, your body quickly shuts down. It depends on how acidic your blood becomes and how quickly it is shifting, but for many people ketoacidosis will kill in less than a day. The damage the acid does to your body can be reversed if caught quickly enough, but if doctors can't fix the acid-base balance in your blood quickly enough, you can get permanent damage in just a few hours, and then die.
> is it possible to unknowingly get into it..
Yes it is possible, but your body will feel really sick, really quickly. People feel super thirsty, start throwing up, have stomach pain, act confused, and smell weird like fruit. Usually people will recognize something is very wrong and will go to the hospital.
Since people with diabetes are more likely to experience it, it's good to learn the signs if you are around diabetics.
It is easily treated at the hospital if it is caught in time.

Any reason you stopped? Is there a better option? Being able to just spin through hundreds of images with the mousewheel and zoom to 100% with a single side-button click was a gamechanger. Needs a little setting tweekage after install, but after that it blows windows' default viewer out of the water.

But obviously you do need help with it, because it's been bothering you enough to come back and continue talking nonsense.
My argument was not whether the hazard is present or not, just that your statement doesn't hold water logically. But you seem to have missed that, again.
You cannot reason that "lack of proof" is "proof to the contrary".

This is why I was able to trick my friends (and myself for a while) into thinking animated jpegs were a thing. I just used to rename the file extension of a gif to .jpg.

Bats are a lot smaller than us and have a lot less blood in their bodies, so gravity has a much smaller influence on their circulatory systems than it does for us. Similar to how we can hang upside down for a lot longer than an elephant would be able to.

Reply to comment by Educational-Eye5076 in ELI5: what actually is keto, acidosis and keto-acidosis..? by Educational-Eye5076
Keto for a diet can lead to ketosis which is just your body burning fat instead of carbs (assuming you’re not eating many carbs with your keto diet). It’s not the same as keto acidosis.
Unless you have some underlying problem, one doesn’t lead to the other.

Reply to ELI5 How is drinking a diet soda different than drinking plain water when it comes to your health? by LucyLegBeard
Few pointers
1)A lot of 0 calorie sweeteners can have positive feed back loops on the body that actually cause the body to be thirsty/hungrier then before leading to constant consumption of beverage in one sitting when initially you may have only planned on having a sip.
-
any form of soda, diet or not, is going to be acidic, and this drinking of acid fluid causes bathing of teeth in the acid. Now think about in movies what happens when stuff gets put into acid, the graphic scene of the object dissolving/liquefying. Well simply speeding, the acidic soda does this to your teeth, albeit at a very small level, however overtime this builds up, leading to erosion of your tooth enamel, and you get dental disease even though you weren’t eating sweats like regular coke
-
sugar normally needs a chemical called insulin to act as a key to open the door to get into cells around your body from the blood. Your body produces insulin in response to sugar being absorbed from your food and entering the blood. Now overtime, the locks on the doors can become busted, especially from overuse and as such the insulin isn’t as a effective and you can end up with sugar being stuck in the blood (this is bad news for the blood and the cells that can’t use the sugar (diabetes).
Well you’d think this wouldn’t be a problem for diet drinks but scientist have discovered the idea that when your bodies taste buds touch something sweet, they prepare the body for all the “sugar” it’s about to absorb and can cause it to produce the insulin even before the sugar gets in the blood. Now if the sugar never gets into the blood because it didn’t exist and it was actually a sweetener like in diet sodas, then you can have a problem, because you have insulin unlocking doors except there’s no sugar waiting out the front. Repetition of This can cause a boy who cried wolf situation essentially, where insulin connecting with the lock may not cause a response, because the cell is sick of them young kids (sweeteners) playing ding dong ditch, except this may happen even when the insulin is trying to unlock the door for actual sugar in the blood, as suddenly you have cells without the sugar they need, and the blood having tooo much sugar (glucose intolerance~diabetes)
Some other unhealthy factors associated with drinking soda of any kind (diet or not) is the caffeine present in many, which you probably no all to well from coffee consumption, causes your to pee your heart out, almost as if you pee more water out then you drink in… well your not wrong, caffeine actually acts as a diuretic and prevents little water vacuums inside the kidneys from sucking water out of the urine (which they normally do to produce the concentrated salty yellow pee) leading to very dilute pee with more water in it then you actually drank making you dehydrated, which isn’t good for your kidneys and other organs if severe enough in short span or if maintained mildly for long period of time

Reply to ELI5: How is it that all directions from the North Pole are South, and not, say, slightly East or West? by QuestionablePotato42
I mean, the idea is predicated on you standing precisely on the North Pole.
In such a scenario, all directions are, by definition, away from the North Pole, ergo they're all South.
