Submission + - Difficult Campground WIFI design 1

MahlonS writes: "I am a retired network hack wintering in my RV in a campground in southern GA. 3 years ago I reconfigured the wifi system to a marginal working ability, It now needs a serious upgrade, prompted by a new cable net connection replacing a DSL. 5 dual radio HP access points connect to a 6th via single or double radio hops in heavily wooded space. The main connect is an old Cisco router. Burying wire is frowned upon, due to shallow utilities. Since I'm not up on current wifi tech, are there solutions out there that would make this system work much better?"

Submission + - Quantum wavefunction is a real physical object aft (nature.com)

  Quantum theorem shakes foundations
The wavefunction is a real physical object after all, say researchers.

"... the new paper, by a trio of physicists led by Matthew Pusey at Imperial College London, presents a theorem showing that if a quantum wavefunction were purely a statistical tool, then even quantum states that are unconnected across space and time would be able to communicate with each other. As that seems very unlikely to be true, the researchers conclude that the wavefunction must be physically real after all.

David Wallace, a philosopher of physics at the University of Oxford, UK, says that the theorem is the most important result in the foundations of quantum mechanics that he has seen in his 15-year professional career. “This strips away obscurity and shows you can’t have an interpretation of a quantum state as probabilistic,” he says.

But I'd like to still have a conceptual difference between /usr/bin and /usr/local/bin; Perhaps support local, but mirror it's contents into /usr/ using symlinks.

I want to be able to install software from source, then wipe it all in one fell swoop if I'd like, which could be done with a mirrored /usr/local.
