You virtually always hit the noise limit before you get to the point where you have to worry about the fundamental discreteness of matter and energy. The majority of quantum experiments involve a lot of cooling and isolating of systems with very good reason!

However, due to the statistics, you can actually detect the effect of discrete electrons, without going to the level of single-electron measurements. But broadly speaking you're correct.

Comment Re:50 percent of the time (Score 1) 167

Good point, the important specification would be "50% of what time?"

I've always had this problem about the whole idea of probability. If the odds of you dying in a car accident are 1/1000000, and you still die tomorrow, what good is the low number of one millionth? You either die or you don't. Probability is only a measure or a larger population, i.e. the fraction that gets the rock, death or whatever. The idea of a probability for a unique event is meaningless.

This is why I like the many-worlds interpretation of quantum mechanics. It gives real meaning to probability as the fraction of universes with the favourable outcome, even if the event is unique from our perspective (though with a total of infinite universes, the definition of a fraction can be tricky). On the other hand, changing the reality to suit a math concept is not necessarily the wisest thing.

Comment Re:"Open source computer"???? (Score 4, Informative) 97

There's basically NO open source hardware out there. And if there were nobody would be in a position to do much with it, because it would take a fab to make any change.

  • 1. There is the good old solder-it-yourself scene, ham radio style, hardware with a hard H.
  • 2. There is a lively FPGA scene, with the complication of mostly closed-source synthesis tools (like compilers). I don't regard this as a huge problem, as long as I can make hardware do what I want. If you're new to the scene, I recommend fpga4fun.

Comment Re:Not next gen (Score 1) 115

next-gen is just marketing propaganda for "new, untested, and hype because it is not old 'X' "

I understand that may apply to Wayland or Mir, but not filesystems, unless you refer to XFS :D

Also, I understand that ZFS is not just a filesystem, as it also covers the functionalities of volume management, kitchen sink, life, the universe, everything, and emacs. Btrfs is a filesystem in the unix philosophy (unless the name refers to 'butterflysystem', in which case it covers all aforementioned functionalities and then some).
