  1. Re:Good on OLPC and CC Free Content Drive · · Score: 1

    If I can provide to everyone all goods of intellectual value or beauty, for the same price that I can provide the first copy of those works to anyone, why is it ever moral to exclude anyone from anything?"

    Good Point!

    BTW, I want your woman -- you cannot morally keep her from me.

    Oh, wait. A copy of the thing of intellect and beauty. I want your daughter.

    12 years earlier

    I bailed on MS after windows '95 came out. It sucked. I have used only Linux since. I suppose that sooner or later everyone will learn.

    12 year earlier!? What took you so long?
    I bailed on MS when MS-DOS 2.0 came out. (Stupid backslashes.)
    I installed Linux and never looked back.

    The one in the book was a later, 32bit computer that competed with the VAX. The book talks about making the 32bit machine backwards compatible with their older 16bit computers.

    Also, the Meccano article says that the Data General Nova influenced Woz. But just because he had a picture on his wall, it doesn't necessarily follow that it influenced his design.

    Your number for the deaths from the Hiroshima blast seems a little high. Every years, the Hiroshima numbers seem to creep up. Here is a good evaluation of both sides of the debate. Whether or not you agree with his conclusion, he makes some good points.

    Quotes from the site:

    "I found figures ranging from 65,000 to 200,000, with the larger figures generally attached to the most recent writings. Astonishingly, there just doesn't seem to be any scholarly study of this subject, but only proclamations by people with a stake in the matter."

    "Writing for Air & Space magazine in the 1990s, I discovered to my horror that at least one editor didn't know the difference between a casualty and a fatality."

    "Even if that hypothetical 21-year-old, laid to rest in 1998, would have otherwise lived into his eighties or even nineties, can we fairly attribute his death to Little Boy? After all, nobody is counting the American prisoners of war who have died in the past ten years, and calling them fatalities of the Japanese PW system."

    I think I just had a brief insight into the mind of women. Her mind is in a cat state. She loves me and hates me at the same time. Her mind is never made up until I make an observation. Then I'm (usually) wrong.

    Maybe that was Einstein and the others' original goal - just trying to understand women. Maybe this Quantum Mechanics thing is just a specialized case of the General Theory of Women.

  10. Re:Watch out NBA on Toxic Moondust Bounces Like A Cannonball · · Score: 1
    "Of course, you know that a personal anecdote is bad logic, and thus bad science, since it is a well-known logical fallacy." "...matches what I saw on that tv show..."

    Your statements have several errors.

    1. Your statement "personal anecdotes are illogical" is a logical fallacy because many personal accounts are true. Perhaps you should have said, "personal accounts are fallible." Courts accept personal accounts as evidence to establish truth. (In fact, courts actively seek personal accounts.) Scientific journals routinely publish personal accounts - almost all scietific papers are an interpretation of experimental evidence. Personal accounts are NOT logical fallacies.

    2. Only idiots insists on rejecting ALL personal accounts without scientific verification. Scientists routinely accept the personal accounts of scientists in other fields. i.e. Physicists routinely accept the work of Biologist without scietific verification.

    3. Truth and logic are not limited to repeatable phenomenon. Strictly speaking, science is limited to repeatable phenomenon. (Science assumes 1 - Cause and effect and 2 - repeatability. Drop these two and the scientific method breaks down.) Until science invents a time machine, we cannot go back to verify historical events. (Even so, a time machine introduces the possibility of changing history - the Uncertainty Principle again.) Scientifically, you can't prove WW2 happened because it is not repeatable. (Think about this in regard to the Evolution v.s. Intelligent Design debate. Too bad we can't go back in time to see when Darwin created the universe.) Courts use science where they can, but must rely on personal accounts.

    4. Your assertion that "personal anecdotes are bad logic" is inconsistent with the rest of your posting. You cite personal anecdotes e.g. "I've also heard that trained marksmen ..."

    5. You cite a TV show in critique of my great-grandfather's account. TV shows are well known for manipulating truth (or maybe superman really can fly.) Also, the eye operates in real time. TV records at 25 or 30 frames per second or 0.033 seconds per frame. Guinness World records lists Bob Munden as drawing and shooting a pistol in 0.02 seconds. http://www.bob-munden.com/guinness1.htm (That's between TV frames.)

    Having said all this, I will readily acknowledge that my great-grandfather's story could be false or embellished. (My sources on this one are pretty good. Some of my relatives like to embellish stories to make them more interesting. Others bore us with ALL the factual details.) Unfortunately, I can't test his story.

    If I remember correctly, Ambrose Bierce made similar remarks. (Sorry, I can't remember which story.)

    As for 22 bullets in flight - check it out before you discount it.

  11. Re:Watch out NBA on Toxic Moondust Bounces Like A Cannonball · · Score: 1

    As I recall, we were plinking with 22's across a small creek. We were above our target at a range of about 10 yards. It was evening with the sun at our back. We would see a quick streak of gold or yellow. We tried to isolate it from other possibilities. I don't think it was a dust trail or heat trail, but the sun reflecting off the bullet. I'm not sre if the color was from the bullet (brass plated) or from the sun.

    I think you are assuming too much...

    Personal accounts by a Civil War era soldier (my great grandfather) say that the cannon balls looked like softballs bouncing across the field. He said that you would think you could put your foot out and stop it, but if you did, you'd lose your leg.

    Also, when the light is right, I've seen 22 bullets in flight. (22 Long Rifle) I was a doubter until someone showed me.

  15. Re:Wall Wart Pet Peeve on Curbing Energy Use In Appliances That Are Off · · Score: 1
    reducing the supply voltage means you need thicker wires in your outlets and power cables

    Some old guy named Steinmetz said you have that backwards. It takes only 1 amp to transfer 100 watts at 1 volt. It takes 10 amps to transfer 100 watts at 10 volts. (Power loss in the cable is related to the amps squared. P=I*I*R i.e. double your amps and you lose 4 times the power in the cable.) (That's why power transmission lines are at such a high voltages - to reduce power loss in 100 miles of cable.)

    A wire of any given size does not have a voltage limit. It does have a current limit based on resistance and heating.

    The insulation is what sets the voltage limit.

    My brother's old '52 Ford truck had push button start. Stock from the factory. Had to use a key to turn on the ignition, then push the starter button. Some cars had a push button on the floor to start them.

  18. Issue isn't Science versus Religion on Many Scientists Admit Unethical Practices · · Score: 2, Interesting

    The issue isn't science vs religion. The issue is truth and honesty vs dogma (or political correctness.)

    Religious and non-religious groups have been guilty of supressing truth to support their agenda. Ditto for big, wealthy groups and small activists.

    Should be pointed out that many famous scientists were Christians. Isaac Newton, Bacon, Galileo, etc. Their stand for truth wasn't against religion, it was against political forces.

    Should also be pointed out that those founding fathers of modern science based it on princples taught in the Bible. Check out the introduction of 1 John 1. (It's toward the back.) Look at the intruduction to Luke. Note the scientific method.
