Atmosphere

Cheers all for the interesting answers. Now I know my computer is lying to me in several ways lol.

Interesting, thanks. You’d think the OS would provide the user with the option to do a “deep delete.”

I do nutritional labeling...the FDA's(U.S.) stance on this(wheat) is merely a recommendation and does not decipher how the wheat was processed, just that it was used at some point during production.

Reading the ingredients/nutritional facts is the only way to determine "health."

It comes down to lack of regulation, lazy consumerism and nothing but a buzz word/phrase, the front of the package is to lure you, the back is to inform you.

Edit:

I own a printing company who's main focus is the printing. It is not my job to consult nor verify the proposed information on the label/packaging as this is the sole responsibility of the manufacturer.

What we will not do is veer from the nutritional facts and ingredients that have been approved in regards to the information on the back of the product.

The front is another animal and considered "free" space where all kinds of phrases can be used hence the recommendation comment. Essentially the "advertising" does not necessarily reflect the quality or amount you're receiving let alone health benefit claims to a certain extent. Claims like lowers cholesterol, heart attack risk, cancer are pretty much regulated but saying "daily dose of fiber, protein, whatever" is not. It just has to contain fiber or protein to fly because it's technically true.

It always amazes me what customers will request to make things appear healthier than they are.

1. The moon itself. It's a pretty big thing in its own right with its own gravitational field, and it's orbiting around Earth. A lot of things that would hit our planet end up hitting our moon instead because it's out there playing defense.
2. The atmosphere. If it's not big enough, it just burns up, and even if it is big, it's both smaller and slower by the time it makes it to the surface, both resulting in smaller craters. When the moon gets hit, it's full-size and full-speed.
3. Weather and plate tectonics. The surface of Earth is changing all the time and even a huge crater will eventually disappear. Craters on the moon more or less just stay that way until another crater lands in the same area and makes a new overlapping crater.

The counterintuitive part is that you normally think about things from the perspective of your car. Your car goes on green and stops on red. My machine goes when I flip the switch to red and stops when I flip the switch to green. If you think about someone else's car at the stoplight, then fine, this matches well, but I also think you're weird if you do that.

Lots of reasons, but primarily because of our atmosphere. Lots of things try to hit Earth, but get burnt up on the way down. That, and our landscape has so many other factors acting on it (weather, tectonic plates, things living on it) that what craters do form can quickly be worn away.

Think of it like a book. It's going to the table of contents and saying these pages are empty and can be used. Yes words are still on the pages but now you are free to erase what's there and write something new. This is why things can be recovered.

Destructive delete is deleting the table of contents entry then going to pages and erasing everything on those pages. Some methods will then write over the data with garbage several times. So with the same analogy it's erasing the page writing gibberish then erasing it so even the intends of the last letters are impossible to make out.

I'd add in a 4th. Coverage. There are a lot of craters that are covered by water, forests, etc.

Your free memory is the memory your computer is allowed to use, which includes any deleted files even if it's still there. Your computer doesn't care about the information in the free memory, but it's recoverable.

Because specifically changing it rather than just 'forgetting' about it would be just unnecessary extra work, unless you aim for extra safety

Because writing them over with zeroes or anything takes considerable time. Basically deleting files would then be as slow as copying them. That doesn’t apply to modern SSDs though, they do reset the memory taken up by deleted files.

To save time. Hard disk writes take forever, and the disk has better things to do than overwrite deleted data.

SSD overwrites would increase wear on the flash. You have a limited number of writes before the flash starts becoming unstable.

No, even if it's the same filename, there's no guarantee that it will be at the same place. Also, if your new file is smaller, for example an empty file, it can only overwrite a tiny part of it if ever it's at the same place.

That is a really good example of this

Just... take a hammer to it. They're hardly expensive.

Memory, yes. Storage, no.

OP is conflating memory and storage. He says memory but means storage.

It's using buzzwords to trick you. These words sound healthy, so it helps companies trick people who don't understand what's going on (and clearly it's working)

​

In reality, it's not inherently healthier (it can be, but simply being whole wheat/whole grain does not make it so).

Much more important to pay attention to calories, and macro nutrients, and ingredients.

nmxt is using "memory" the same way OP is: to refer to storage. Technically, storage is a type of memory. Not all memory is RAM.

There are three major causes:

1. Erosion. Wind, rain, snow, ect. gradually wear down craters on Earth's surface over time.

2. Fewer surface impacts per m^2 . Because the Earth has a relatively thick atmosphere, a lot of the smaller rocks break up before hitting the surface or slow sufficiently to mitigate their impact on the surface.

3. Tectonic activity. Unlike the Moon, the Earth is still tectonically active, with volcanos faults gradually erasing some craters.

The earth has an atmosphere. When the earth passes through a cluster of asteroids (this is what causes meteor showers) the vast majority of them burn up in the atmosphere due to air resistance before they can reach the ground to make a crater. The moon technically also has an atmosphere but it is so thin that we don't really consider it an atmosphere. It can't be breathed and it won't slow down, heat up, and burn away objects that pass through it like earth's atmosphere. This means that when the earth and moon pass through an asteroid field the earth is protected while the moon just gets slammed over and over again.

On top of that, the earth has geological activity such as erosion which can erase the signs of old meteor impacts. The moon doesn't have this so every time a meteor strikes, the crater remains there until another meteor hits and obscures or covers it up with another crater.

You can 100% clear up memory by closing all those chrome tabs.

Wait, this sounds like it’s still consistent with stoplights. Green means safe/off and you can interact with said machine (equally for cars, you can interact and drive through) whereas red means danger/energized (for cars, you should not interact with driving and stop the car). For me, this sounds like it checks out! 👍

In short: Atmosphere.

A lot of meteors that come in contact with earth burn up in the atmosphere, and don't make an impact.

Furthermore, there are a lot of impact craters that have been worn down by weather, covered over by plant growth, and so forth - again, essentially due to the fact that we have an atmosphere.
