    The US Civil War was fought to decide this issue. States cannot secede from the US. Investors aren't stupid, so what are they trying to show? That they think we must be? That they'll throw money at anything drawing attention to their displeasure with the president-elect?

    That making a hyperbolic proposition as an opening is just part of the art of the deal?

    Heck, if i had been prosecuted for my cracking in HS, I would've been just another hard case in juvie instead of the valedictorian. I graduated from MIT, and now I understand that the HS and Uni years are periods of ACTIVE learning. If a pupil with exceptional aptitude is suspected of some illicit activity, "I just wanted to see whether it would work," should be grounds for exoneration. Or for sentencing to MIT.

  16. Re:Whoa? on Gmail Users Get A Storage Boost [updated] · · Score: 1

    Excuse me? Where the heck do you get that?

    I wrote "sample rate to record FMV" when I meant average data density to store watchable video.

    I got 733kbps by dividing 700MB by 120 minutes (actually the quotient is 778kbps; oops.) I have fit four 30 minute episodes of Red Dwarf on one CD-R. Playback quality on my laptop is fine, in my opinion. Obviously, higher quality video requires more storage space. Home camcorders save 2 hours of video on a 4.7GB DVD-R. At this density, a 750,000 hour lifetime requires 1.7PB.

    Anyway, we've bracketed the storage capacity required for a remarkable feat. I wonder what the barriers are to making hundred-TB hard drives at consumer prices.

    Assuming 733kb/s sample rate (700MB/120min)to record FMV w/sound

    It would take about 246TB to save video of every second of someone's life.

    That's about a quarter of a petabyte.

  18. Physics of Power Grid Surges on Yet Another Big Solar Flare · · Score: 2, Informative

    CNN: "Power grids in the northern United States and Canada felt the effects of the first storm. Utilities endured power surges and closely monitored their systems to prevent surges, according to NOAA."

    Check out this article for more details on how solar flares cause these surges.

    Excerpt:
    "If (when) this flow of charged particles and embedded magnetic field collides with the Earth, it dramatically disrupts Earth's geomagnetic field and ionosphere, changing the terrestrial magnetic fields ... This magnetic field change, which occurs fairly rapidly, then induces currents in nearby conductors. ... In those areas that do not have high conductivity, such as those areas that contain igneous rock, the induced current flows through any available current path-typically, the long utility system lines for power, gas, oil, water, and telecommunications."

  20. Physics of Flare-Induced Power Outages on NASA's Earth Observatory Shows Solar Flare · · Score: 5, Interesting

    Article on solar flares and power outages.

    "If (when) this flow of charged particles and embedded magnetic field collides with the Earth, it dramatically disrupts Earth's geomagnetic field and ionosphere, changing the terrestrial magnetic fields, and therefore causing currents to flow in the upper ionosphere, ...in the earth itself, and in long distance conductors. The interaction of the [Coronal Mass Ejection] with the Earth is referred to as a geomagnetic storm."

    "This current can cause saturation of the large power transformers at either end of the transmission line, creating a host of undesirable effects. ... Typical undesirable effects range from voltage regulation difficulties, to highly nonlinear sinusoidal primary and secondary currents, resulting in circuit breaker tripping; to creation of local hot spots within the transformer, resulting in transformer failure. ... The effects of [Geomagnetically Induced Currents] were dramatically demonstrated during March 1989, when GIC caused a cascading failure in the Quebec Power system, putting nearly nine million customers in the dark, in less than 90 seconds."

  21. Blackouts are Possible on X17 Solar Flare Sends 2B Tons of Plasma at Earth · · Score: 2, Informative

    The above article references the 1989 geomagnetic storm. During that storm, large blackouts occurred in Quebec due to induced currents circulating in the power grid. Transformers are built to transmit AC current and do not like it when large quasi-DC currents appear out of the sky. The transformers tend to overheat and fail, and in a fragile power grid, this can lead to cascading failures and blackouts.

    More information about this phenomenon (and an engineered solution to it) is available on my company's website.

    To KDLynch/AC,

    You seem to be able to speak authoritatively about broadcasting issues. Since so many slashdot articles deal with this topic, I wish you would post under a username so your posts would be easy to find. Unfortunately, most AC posts get lost in the noise.

    Let's see....

    1 Hogshead/63 gallons =
    0.00198 miles/gallon or

    Perhaps Grampa drives an SUV?
