  1. Re:perhaps the problem is with the DVDs? on A Storage Solution for Lots of Digital Photos? · · Score: 1

    Whenever I burn, I verify the media to ensure that what I burned actually matches what was on the drive.

    One problem with that is that CDs and DVDs use error-correcting codes. Unless you know how many errors have been corrected by the drive, you can't tell the difference between a perfect disc and one which is just below the threshold of having uncorrectable errors.

    Your "smart" toaster sounds like something that Microsoft would come up with. I'd rather have the talking one from Red Dwarf.

    "refuse to toast until you set it up"? Why not just fall back to the traditional manual control? If I want "smart" mode, I'll push a button for it.

    As for remembering the setting I used last time, that's no good unless it also knows that I'm toasting the same kind of bread as last time. It doesn't allow for the possibility that I might want my toast darker than I did yesterday. Do I have to create a new account for that? Can I even can do that, given that it's using biometrics?

    If you're adding electronics to a toaster, give it something that improves the fundamental process. Measure the change in surface reflectivity to detect done-ness, instead of just a time or temperature control. Control humidity by turning on a small fan. Apply different amounts of heat to the top and bottom surfaces of a bagel. Detect when the crumb tray is about to catch on fire and shut off the power. Etc.

    I'm not a horticulturist, but from my understanding plants take CO2 (1 part carbon and 2 parts oxygen) and with the power of the sun break it down into carbon and release the oxygen.

    The released oxygen actually comes from water that has been split using energy from the sun. The hydrogen from the water is combined with CO2 to produce sugars, etc.

    The chip itself should be good down to DC. However, the output is usually capacitively coupled to eliminate the DC component. Increasing the size of these capacitors will move the low-frequency cutoff to a lower frequency.

  5. Re:Power versus Frequency on World's Most Powerful Subwoofer · · Score: 1

    Correct me if I am wrong but power is measured in Watts...and usually for speakers and subwoofers, you need to look at RMS Power Consumption.

    You also need to look at "sensitivity", which is the sound pressure level generated per Watt of input power.

    What is Acrylamide? It is just a chemical that food manufacturors put in French Fries and Chips.

    It's not something that anyone "puts in" fries. It's a substance that forms during the high-temperature cooking process. From your link:

      Acrylamide forms as a result of unknown chemical reactions during high-temperature baking or frying. Raw or even boiled potatoes test negative for the chemical.

    Think about it, not just foods but all chemicals.[...]

    Here are some chemicals:
      - Adenosine triphosphate
      - Ammonium perfluorooctanoate

      - Oxalocacetic acid
      - Oxalic acid

      - Pyruvic acid
      - Xanthophyll
      - Xylene

    Many of these are found in all-natural foods like fresh fruit and vegetables. Some of these chemicals are essential for life, while others are harmful. It is not useful to group them together under an "all chemicals" label and then conclude that they must therefore be bad for you.

  22. Re:Faster than light doesn't mean backwards in tim on Speed of Gravity Experiment Challenged · · Score: 2, Informative

    But doesn't this argument assume that the special theory of relativity applies?

    Yes, this scenario assumes SR.

    Because if you look at the general theory of relativity, you have to account for (speaking from the point of view of one reference frame only) the massively negative acceleration as the message is stopped and bounced back.

    That's not an issue if you're only dealing with messages, rather than people (e.g. the "twins paradox"). To send a message between two reference frames, all you have to do is send a pulse of light between them. The light may be a different color when it's received, but the information content will be the same.

    I'm sure there's a better description somewhere, but the basic concept is:

    Two pairs of spaceships: A,B ; X,Y.

    A and B are at rest relative to each other, and are some horizontal distance L apart (in their reference frame).

    X and Y are at rest relative to each other, and are some horizontal distance L apart (in their reference frame).

    The XY pair is moving horizontally past the AB pair. When A and X are next to each other, A sends a message to X (using "normal" methods). X then relays the information to Y using some faster-than-light channel. Some time after Y receives the message (from Y's perspective), Y and B are next to each other. Y relays the message to B (with normal methods), then B relays it to A using a faster-than-light channel.

    For appropriate numbers, using the standard coordinate transformations, it will turn out that the time of arrival at A is earlier than the time at which the message left A. This is pure SR (except for the faster-than-light channel), in flat space, with no acceleration required.

  23. Re:Faster than light doesn't mean backwards in tim on Speed of Gravity Experiment Challenged · · Score: 2, Insightful

    Contrary to popular opinion, the ability to travel or send information faster than light does not allow one to travel backwards in time.

    Maybe not "travel", but you can send a message backwards in time. This assumes that you can send faster-than-light messages in two different reference frames that are moving with a high relative velocity - you bounce the message back and forth between the reference frames, and the net result is that it arrives at its point of origin before it was sent.

    So, they've had one up and running uniterrupted since early 2001, huh? I call bullshit.

    Why do you think so? It's not like Ballard is a new company - they've been working on fuel cells for years (when I graduated university in 1995, some of my classmates went to work there). I can easily believe that they've kept a lab unit running since 2001. According to their corporate website:

    Ballard Power Systems Inc. was founded in 1979 under the name Ballard Research Inc. to conduct research and development in high-energy lithium batteries.

    In 1983, Ballard began developing proton exchange membrane (PEM) fuel cells. Proof-of-concept fuel cells followed beginning in 1989 and from 1992 to 1994, sub-scale and full-scale prototype systems were developed to demonstrate the technology.

  25. Does this apply to CDMA? on Research: Mobile Phones Disrupt Aircraft · · Score: 1

    I glanced at the article, and I didn't see any mention of CDMA phones being tested. I have a CDMA phone, and I have never seen it cause interference to nearby electronics. On the other hand, I've seen a GSM phone cause very noticable interference to a nearby computer monitor (every few seconds there would be a pop from the speakers, and the picture would jump).

    Of course two anecdotal data points aren't very convincing, but I think that the type of modulation should be considered when evaluating the risks of cell-phone interference.
