This is cultural evolution, rather than genetic evolution. It's as different entropy in thermodynamics, contrasted with entropy in information theory. One of these things is not like the other. Yes, there are similarities, just as there are similarities between a Volkswagen Beetle, and a picture of a Volkswagen Beetle.

Comment: Re:The diode voltage drop would cause power loss. (Score 1) 395

The voltage drop across an ideal diode isn't resistive, and doesn't cause a power drain. The *resistive* voltage drop across a real-world diode is tiny. Diodes are actually very efficient devices. Don't take my word for this, you have access to this wonderful research tool called 'The Internet'. Alternatively, buy a diode, a resistor for comparison, a power supply, and do the calorimetry.

With respect, you don't understand enough about the possibilities. If you look up a circuit called a Cockcroft-Walton Voltage Multiplier, you'll find that it represents a capacitor/diode array where the diodes are arranged such that the capacitors are charged in parallel, but discharged in series. Same principle.

Whenever I've read any of your posts, I've always been impressed and please to see the intelligence behind them. This post made me smile. For what it's worth, I'm typing this under Archlinux and Gnome 3, but I see the truth in your criticisms; I view the world in much the same way, but with different emotional loadings. Enjoy your semi-retirement.

It still doesn't explain why the good guys just didn't find a series of large rocks, paint them very black and fire them from a railgun at some stupendous velocity whilst simultaneously deploying chaff, radar jamming and any of the billion other things they might have done to defeat the Death Star's sensory facilities.

The whole space battle thing is deeply broken, in general. True space battles would probably involve stealth ships dispatching oodles of drones, lots of incoming, light-speed-lagged statistics, followed by death. But then again, in sci-fi terms we're mostly still at the Heavily Muscled Guy With Fashionable Facial Hair Sitting At The Front Window Driving The Spaceship, uh, stage.
