    It's actually pretty insightful that there are an infinite number of alternatives. You have limited their choices only to words in human languages; however, CBS' chosen alternative, $#*!, isn't even in that list. For example, they could have chosen an unpronounceable symbol, like The Artist did.

    I think it's a fair guess, though, that there is probably no choice that would have made the Parents Television Council happy. Glem? Fintlbumf? Frznl? After all, the show is plainly called "Shit My Dad Says" no matter what they choose to replace "Shit' with.

    Approximate radius of a ring spinning once per day that has centripetal acceleration about equal to earth's surface gravity.


    g = 4 * pi ^ 2 * r * f
    r = g / ( 4 * pi ^ 2 * f )
    r = 9.81 / ( 4 * pi ^ 2 * (1/86400) )

    r ~= 21,500 meters = 21.5 km ~= 13.5 miles

    If the ring was 500m wide, that would give you an area of about 1,000 hectares, or 2,500 acres. About one tenth the area of Manhattan. I am not a farmer, but I think the rule of thumb is that you can raise a cow per hectare without using fertilizer.

    This has nothing to do with the skills (or lack there of) of programmers in 1982, but everything with the CPU features available. The 8088 and anything else IBM might have used did not support memory protection or any form of privilege separation. UNIX needs those features in hardware to run.

    Canada has even more guns per capita and less homicide rate due to their strict enforcement of gun laws.

    Commonly stated, but only half true. Canada has a lower intentinal homicide rate (1.83 per 100k residents, compared to 5.4 in the USA), but also a lower gun ownership rate (31.5 per 100 residents, compared to 90 in the USA).

    Some have claimed that gun ownership in Canada is more popular than official figures suggest, because of a purported plethora of unregistered rifles. By law, all guns must be registered. However, if gun ownership is a lot higher than quoted, then it cannot be the case that gun laws are "strictly enforced".

  14. Re:cu on Need Help Salvaging Data From an Old Xenix System · · Score: 1

    It's Xenix. Ancient Xenix.

    It was a bulletin board system. It probably has kermit (1981), xmodem (1977), maybe ymodem (1985), and possibly zmodem (1986) already installed on it. Others have mentioned uucp (1979?), which was probably included in the default installation of Xenix.

    Finding a way to compile and transfer Kermit to such an ancient system would take some serious archeological research, and some luck, because I certainly wouldn't expect to find it in Xenix from the days when Microsoft published it.

    I have personally written a basic stop-and-wait kermit in Bourne shell for a lark. It's not as hard as you think.

  16. Re:20 times more random? on New Method for Random Number Generation Developed · · Score: 1

    It's hard to know what "20 times more random" means, alright. They probably measure randomness using entropy per bit, and then say that 1-H is smaller by a factor of 20, so therefore the numbers are 20 times more random.

  17. Re:20 times more random? on New Method for Random Number Generation Developed · · Score: 1

    I'm making a bit of a guess.

    A random process can generate a random bit. If the process is random, then you can't predict with certainty what the next generated bit will be. However, what if the random process generates a one bit 90% of the time and a zero bit 10% of the time? Great! It's random, but you can predict what the next bit will be 90% of the time. I think this is what they mean when they say that a particular generator is not very random. It has a bias. The closer a generator is to having neutral bias, the more "random" it is, because there is less benefit to always picking the biased bit as the one that will come next.

    A poor random source can be improved by combining many results into a single result. This is probably why a bigger array produces less predictable bits. Staying with the 90/10 example above and combining bits using exclusive or, we get the following truth table, with the likelihoods of the outcomes listed:


    A xor B = R [P]
    0 xor 0 = 0 [1%]
    0 xor 1 = 1 [9%]
    1 xor 0 = 1 [9%]
    1 xor 1 = 0 [81%]

    So by taking two results from this pretty terrible random variable, the combined result is a zero 82% of the time and a one 18% of the time. It's less predictable.

    As you combine more and more bits, P(0) and P(1) asymptotically approach 50%. I'll do a hand waving argument to convince - you can google for the real deal. If you xor a bunch of bits together, the result is one if there are an odd number of one bits and zero if there are an even number of one bits. If you take a really long sequence of bits from a biased random source, the chance of having an even number of one bits is about 50%. The longer the sequence, the closer the probability is to 50%.

  23. Re:Yeah! on Massive Solar Updraft Towers Planned For Arizona · · Score: 1

    It isn't clear to me that this plant will cool the air. A greenhouse has the effect of warming the earth, because solar radiation is transmitted, but thermal radiation that would have passed through the atmosphere is retained. You say that the thermal radiation heats the atmosphere, but that is not completely true. Some of it passes through the atmosphere without being absorbed. The increase in absorption due to carbon dioxide in the atmosphere is hypothesized to be a source of global client change. This hypothesis would be trivially proved false if all the thermal radiation from the Earth's surface heated the atmosphere. This greenhouse is certain to prevent more thermal radiation from escaping into space without absorption than the atmosphere on its own.

    Furthermore, any heat that the turbine converts to electrical energy will be converted back to heat in a very short period of time by appliances connected to the grid and by line losses - nearly 100% of it will be heat within a minute of conversion to electricity.
