So what was the original saying? As I see it, this phrase is wrong no matter how you look at it. Because all ram is used at all times, for example if you have 32GB of free ram, the kernel will use all of it as a page cache to speed up the file system. The more free ram you have the more files can be cached, avoiding access to the disk when you read them.
This phrase is just plain wrong. Unused ram is used for the page cache by the kernel. You must always have some ram free or else the whole system will not operate without a page cache. Larger page cache allows to cache more files from the file system.
It also helps that it’s very strict, both in syntax and borrow checker. A normal person needs 6 months to stop fighting the compiler and start coding proficiently. LLMs stand no chance.
No, but it doesn’t mean the other answer is invalid too. If there is no reference in the picture to tell what kind of light condition it was shot at, both answers could be possible.
The yellow background could be lit by another window or a different light source, so one could argue we don’t have a good reference to tell. But the point is that the “picture of a thing” is not “the thing” itself, and there is always a possibility that they are different.
You missed the whole point. If I take a white dress and then shine a blue lamp on it, then take a photo.The pixels will be 100% blue, but would that mean the dress itself is blue?
Not even that, it’s more expensive than natural gas and you can’t even use it in a combined cycle plant. So you pay more and get less energy for it. You don’t even need to mention pollution to show it is a terrible fuel.
