A useful maxim for computer stuff and Unix people.
But I can also apply this to wood and plastic! (Yes, I am that sick.)
The under-sink cabinet in my kitchen is cramped: a normal trashbin, a plastic bag dispenser and a bin for recyclables vie for space, not to speak of the water filters and all the other stuff in there.
I'm not just a packrat but also a perfectionist, and it annoys me greatly every time when I must move the recycling bin around so that neither the dispenser nor the other bin knock into it when the doors are closed.
But that's solved now: I've automated the bin adjustment process! And it's a super-low-tech solution too, no electronics required! hehe
