RAM and cpus use the proper 1024 B to kB to MB to GB. Unlike hdd makers that paid ISO to retroactively make it 1000. Or worse internet providers that use bits (b) instead of bytes (B) (reasoning that signal transmission uses bits).

It's definitely the kernel and bios reserving pieces. They need it to run the computer, after all. Afaik even other hardware can reserve memory for itself, like gpus or network devices.

    I got a knife my grandfather used, that has been sharpened so much it looks like a fillet knife. Ergonomics? It cuts, I don't care. It's a good reserve.

    Good point about dimples though. But thinking about it why wouldnt I be able to sharpen it? A knife's like 2mm thick while a dimple is idk I don't have one such knife, but it's probably much less then 0.3mm and the edge obviously tapers.

    Stuff sticks to knives because they are flat. They need to have dimples for stuff not to stick. Even with ultrasonic vibrations things will stick because things are elastic and sucktion.

    I doubt this knife has the power for its vibrations to make a meaningfull difference in cutting.

    That's my opinion at least.

    YES! There are leevees literally thousands of years old (in mesopotamia) because they planted trees on them.

    Never understood why they are not made like that. Engineers are usually smart people so why make complex structures that need maintanence when you can just plant trees on them.

    There were plans for a train. Problem is, other then the obvious, that you still need a lot of water for the steam turbine.

    I think there's a youtube video about it.
