  1. Re:Right ... but still a decimal system ;-) on The Changing Definition Of 'Kilogram' · · Score: 1

    IIRC 0 Fahrenheit was thought (incorrectly) to be the lowest temperature for liquid water with an optimal amount of salt (NaCl) added.

  2. Re:yeah it's a mess on The Changing Definition Of 'Kilogram' · · Score: 1

    Are these 6, 7, 8, or 9 bits per byte?

  3. Failure chance 1 in 50 on NASA says Columbia Rescue was Possible · · Score: 1
    Moving the astronauts from one ship to another should be much less risky than the risk of launch and reentry, based upon history. So: risk of launch failure of rescue mission times number of persons in smallest possible launch crew, plus risk of reentry failure times number of people returning. I get an expected loss of life of 0.12 lives.

    If the rescue launch fails, the probability of the first vehicle returning sucsessfully is unchanged.

  4. Capitalism is on Monsanto Plant Patent Case Winds On · · Score: 1

    a social system based on the recognition of individual rights, including property rights, in which all property is privately owned. (Ayn Rand)

  5. Re:The bottom line is this... on Monsanto Plant Patent Case Winds On · · Score: 1
    I haven't seen anything that proves that the farmer KNEW he was using MONSANTO's roundup resistant plants. He could have assumed he had a wild mutation.

    It's a weak argument, but the goal is "innocent until proven guilty" (beyond a reasonable doubt.)

    The proper sequence of events would have been for Monsanto to have proven by genetic analysis (not merely by roundup resistance) that the plants were Monsanto's, then obtained a restraining order to prevent the farmer from making further use of Monsanto's product. What actually happened sounds to me like a failure of due process.

  6. Profits on Monsanto Plant Patent Case Winds On · · Score: 1

    A company that cannot make a profit will go out of business. A person who cannot make a profit will die (or live by theft).

  7. Patents don't last forever on Monsanto Plant Patent Case Winds On · · Score: 1

    After about 20 years he should be able to plant these seeds freely.

  8. Free will on Monsanto Plant Patent Case Winds On · · Score: 1

    "trick people into thinking they have free will" ... So you didn't use free will to write your comment? You were forced to write it, or tricked into writing it? You don't believe what you wrote? ANY argument against the existence of free will is self-contradictory.

  9. They exist on Future of 3d Graphics · · Score: 1

    There are some specific purpose processors, such as FFT chips. DSP processors might be considered to fall into this category. When a need is seen and a processor can be sold or used at a profitable volume, it may be developed, often as an asic. Another example is echo/reverb chips used in the audio industry.

  10. GM on Creating Car Free Cities · · Score: 1

    GM bought the LA streetcar system in order to run it at a profit and to have a customer that would buy only GM products. GM was unable to run the system at anything close to a profit, even considering the captive market. When it became clear that nothing could save this obsolete money-loser, they shut it down. The only thing that could have saved the LA streetcars would have been for the city to take them over and run them at ever-increasing losses.

  11. Video noise filter on Preserving VHS Recordings For Another 20 Years? · · Score: 1

    Under Linux, mjpegtools/yuvdenoise. Several frames are averaged together in an exponential-decay manner, command-line adjustable. There is motion-detection adjustable up to a distance of 24 pixels. If you extract single frames from the resultant video, yuvdenoise can make the difference between unacceptable and acceptable noise levels. The biggest problem I've noticed is that color lag occasionally makes red blotches in light flesh areas. Overall, I'm pleased.

  12. Science history on A New Approach to Teaching Science · · Score: 1

    When I was in sixth grade (1961), my class listened to weekly radio broadcasts of science history -- mostly the history of single inventions such as the incandesent light or the sewing machine. I found them dull as dirt; I was interested in how things worked and the nifty things that could be created, not how things already long in existence came to be. I suspect this is a personal difference. If you're already interested in science, many (not all) people find the history interferes with learning the science. If you're not interested in science, science history provides context, structure, and motivation to make science comprehensible and interesting.

  13. Re:geez on Making a House That Will Last for Centuries? · · Score: 1

    A friend of mine was killed - asphyxiated - by a gas stove when the pilot went out and the house filled with fumes. A house with gas appliances indoors is unfit for human occupation.

    Yes, we are lucky you're not president. We'd all be dead soon.

  17. AFL-CIO on AFL-CIO Proposed Reforms for the H1B Program · · Score: 1

    If the AFL-CIO proposed it, then its only purpose is to advance the power of the AFL-CIO.

  18. Z800 was produced on More Drooling Over The Opteron · · Score: 1

    Zilog made it and it even had a second source (a Japanese company). The problem was, it came out about two years too late to have an effect on the mainstream computer market. I made hardware based on the Z800 and wrote a program for it. Zilog flubbed the chance to maintain their lead in microcomputers many times by failing to rapidly develop the appropriate new products.

  19. Motorola vs Intel on More Drooling Over The Opteron · · Score: 1

    According to yahoo finance, both Intel and Motorola had 26.6 billion dollars in sales in the trailing twelve months.

  20. Boron on 85 Big Ideas that Changed the World · · Score: 2, Interesting

    Driving through the midwest in 1965 (Ohio, I think), there were occasional gas stations with the brand name "Boron". I was informed that the "Boron" chain was so-named because they used a boron compound as an anti-knock agent. Apparently this was not a great commercial success. I have no idea if toxicity was a problem, but my father said the company he worked for (Commercial Solvents Corp.) helped "Boron" with some difficulties they had keeping their compound dissolved in the gasoline.

  21. Re:Viable Backup Media? on Inside One Of the Last Vinyl Record Manufacturers · · Score: 1

    It's not too hard to make vinyl recordings if low quality and limited playback aren't concerns. In the 1950's dictating machines ("Sound Scriber" and others) were available, making recordings on thin, pale green disks. IIRC the disks were about the size of a CD, and the machine was about 7x11x3 inches. The first playback sounded OK, but damaged the disk, so that 2nd and later playbacks were scratchy.

  22. Re:thermocouples on Sandia's Smart Heat Pipe · · Score: 1

    Thermocouples in this application would be very inefficient. I am by no means an expert in this field, but think of efficiencies on the order of one percent. Impractical and not worth the extra expense.

  23. Re:Not addressing the real problem on Sandia's Smart Heat Pipe · · Score: 1

    Each generation of smaller device dimensions is more power efficient. Smaller devices have lower capacitance and run at lower voltages. Power = Frequency X Capacitance X (Voltage squared). The reason total power dissipation is going up is that more things are being done faster (Faster is higher Frequency, and total Capacitance is rising because the decrease in individual device capacitance is overwhelmed by the great increase in the number of devices.) The low power processors are available, powering PDAs, etc.. But if you want to do a lot rapidly, you've got to use power.

  24. Re:It's like English Measurements on Bringing Back the PDP8 · · Score: 1

    Not necessarily even numbers. Honeywell used 9 bit bytes circa 1970.

  25. Re:Too Those Who Think 2 MP or 24 bits is enough.. on Canon Mistakenly Announces 11-Megapixel Digital Camera · · Score: 1

    The argument goes both ways. The random nature of film allows bringing out higher resolution than the 2 pixels/LP, at the cost of lost contrast. On the other hand, visual comparisons often give digital the advantage in image attractiveness (unless there are problems with jaggies) because at the resolution limit film looks noisy.
