    Maybe he didn't use 'large' quantities of dye for sufficiently large values of 'large'. 8-)

    I was going to originally propose radioactive fluorescein so that you could compare the isotopic ratios to determine how long it took the sample to traverse the path, but realized that the appearance of the dye would do the same thing. Duh. I like the radioactive tracking, however. If you make it radioactive enough that it's not only radiologically hot but physically hot, it'll melt it's way through any constrictions.

    Pour a large quantity of fluorescein into the melt water in question. Observe the ocean surrounding the glacier (perhaps from a satellite) for a bright yellow-green patch.

    If you want to trace the flow, introduce a neutrally buoyant, screaming hot but short half-life gamma radiation source into the meltwater. Track it via sensitive correlated gamma detectors in 3 dimensions. Some choices include Sodium-24 with a half-life of 15 hours and gamma energies of 1368 keV and 2754 keV, or Ir-188, or Y-90.

They can prohibit you from having a gun on their grounds, sure, but they certainly don't have any right to force you to open your car nor can they stop you from leaving the grounds on your time to have a good time at the firing range.

    That situation sounds suspiciously like the fight concealed-carry permit holders are waging against prohibitions of carrying a legally-owned handgun in their car on company property. They're certainly able to prevent me from carrying inside their buildings and while walking around their property, but the state says I can have one legally in my car. The argument is that my car is the same as my house - no searches without probable cause, so the company has no business worrying about things that stay in the car.

  8. Re:Surprise, surprise! on The Gene Is Having an Identity Crisis · · Score: 1

    I've always thought the same thing. To a lesser extent the 'dark matter' and 'dark energy' folks are guilty of the same sort of excess. They don't know what it is (if anything) but you'll hear statements like 'Dark matter is matter than doesn't generate or reflect light but interacts gravitationally". We have no idea if that's really the case. I'm one to always use more circumspect language - "There is an effect present that mimics a distribution of currently-unseen matter" or some such.

    I agree wholeheartedly with this quip from the Wikipedia page on Dark Matter:

    It has been noted that the names "dark matter" and "dark energy" serve mainly as expressions of human ignorance, much as the marking of early maps with "terra incognita."

    I second the rifle motion. I'm still amazed at the differential equations that are involved with external ballistics. Did you know that scientists have yet to develop 'closed form' equations for bullet flight? They have excellent approximations, but the formulas rely on empirical measurements of the bullet flight to derive so-called 'ballistic coefficients' for different velocity subranges for each bullet weight and shape. Sierra Bullets has a wonderful section of the equations of flight in their reloading manual that they have released on the web. I recommend it highly to anyone with a mathematics background - check out the 4th edition information starting with section 6.0

    If you're able to use a breadboard to prototype your circuits, you're not building interesting stuff! 8-)

    Seriously, it's gotten to the point where RF and computer components are either all SMT, or are made using stripline techniques. It's almost impossible to prototype anything with UHF or higher frequencies on a breadboard because the layout and composition of the PCB begin to play a major role. Luckily manufacturers are beginning to bundle related circuits into RF building-blocks-on-chips so that the external connections are not operating at the RF freq which relieves some of the layout angst.

    Perhaps you are reading-impaired. I specifically mentioned that the layoffs occurred at corporate HQ, were not the same ones as have resulted from store closures, and were in IT. Firedog is categorically not IT; Senior developers, project managers, etc are, and were the folks laid off last Friday. In Richmond, the IT arena is being flooded with laid-off workers, so it is kinda difficult to find work if you've recently been laid off. There have been many layoffs at many of the area's largest employers, and I'm afraid there are more to come.

    10% fiscal losses does not translate into 1 in 10 people shoplifting. I also think you may be conflating shoplifting to what is euphemistically called 'shrinkage' in the business. Shrinkage is when an employee totes a TV out the back door. I must say that having 3 different point-of-sale systems at CC has only helped those employees bent on stealing. If the inventory says there are 5 TVs in stock and the employee counts 6, then it's their duty to take one home to make the inventory come out right.

    What seems to have not made it out of the Richmond area is that they laid off 500-800 people last Friday from Corporate in addition to the ones they're laying off from the store closures. That's a lot of people to dump into an already poor IT market.
