My camera has several thousand very tiny artists inside it who paint what they see when the shutter opens. Thanks, Sir Terry and we all really miss you.
I’m saying that it doesn’t matter whether magnets are magic, as long as we can predict what they do. 
Back when I read comp.arch, some people there said that you could understand modern computer design as a fight between hardware people providing memory and software people using it up.
Nothing new about that. Back in 1974 one of my fellow grad students modified our PDP-11/20 by adding more memory, which got it up to 28K IIRC, “enough for anybody.”
Within five minutes I modified my Star Trek game (Pascal version of the one in Ahl’s book of BASIC games) and the program ran out of memory.
No virtual memory on that thing.
Nature abhors an unused bit.
Well, and that is true, really. Modern memory management uses the lazy approach, where it keeps chewing away at untrodden memory even after large chunks of previously used memory have been released. Because, if you have it, you should not just leave it lie on the shelf – plus, the freed up memory will continue to be tagged with what it was used for, so that a process can be resurrected after quitting and have some of its key data still in memory.
Just think, 10 - 15 years from now we can come back to this thread and say “Tee hee. Remember when we thought that crap was the shit?”
OK, I get, you’re saying you’re sure that they’re magic.
