Comment: Re:Heisenberg compensator ... (Score 1) 83

Heisenberg's uncertainty principle is just the Fourier uncertainty principle applied to QM. Position is the Fourier transform of momentum. You get an uncertainty principle between two things which are related by the Fourier transform, it's just a fact of math and not some mysterious property of quantum systems.

One way to passively burn more energy that I don't see mentioned enough is to simply lower the ambient temperature (and don't add more clothing). Staying in a cooler room (or not using a heavy blanket when sleeping, etc) can use a significant amount of extra energy. Sleeping humans use between 20 and 80 kCal/hour, depending on ambient temperature, blankets, etc. (80-20)*8=480kCal potential burn, per night of sleep. Over the course of a week that's 3360kCal, or nearly a pound of body fat's worth of energy. Use your basal metabolic rate to burn more energy by staying in cooler environments.

The problem with the Turing Test is that it's so often done wrong. The test is supposed to be adversarial, with two humans and a computer. One human (the investigator) has two terminals and can communicate with the other human and the computer, but doesn't know which is which. The goal of the computer is to convince the investigator that it is the human. The goal of the second human (the foil) is to convince the investigator that he or she is the human. This is then supposed to be repeated with different investigators and foils, and only when a statistically significant portion of the investigators fail is the test passed by the computer.

Investigators should be trying to find which one is human, not simply chatting with the computer. Too often people are simply connected to a chatbot and not told that it might be a computer until after the fact, no foil is involved, etc. The test is also often declared to be passed if even a single investigator fails.

Except that a single tab pretty much never dies. I've not had that happen for quite a while now.

In fact, it stopped happening about the time I uninstalled all plugins (flash, Java, etc). Probably not a coincidence. I use Chrome for the few things that need Flash, which is thankfully getting even rarer these days.
