    In addition to the Japanese project, a Russian nuclear sub crew will get some live-fire training while launching the (privately-funded) Planetary Society's Cosmos 1 solar sail project in March of 2005.

    There are also companies that partner with Russian airbases to take wealthy Westerners up in basically anything with wings. Having a Yankee in the back seat pays for the gas and maintenance, and helps the pilot get some flight hours.

    Hey, if you're short on hard currency to pay your troops, why not take some Western cash and make someone happy (whether it be through launching a space probe or giving 'em the ride of a lifetime) while your troops are getting their training.

    Suppose we drop a cheap ($10M) set of nukes across Baghdad and in doing so, kill 1,000,000 people.

    $147,010,000,000 spent.
    1,017,000 Iraqis dead.
    24,000,000 Iraqis liberated.

    That comes out to:
    $1,445,526 - spent to kill each Iraqi, and
    $61,204 - spent to free an individual.

    In short, the nuclear annihilation of 1,000,000 civilians would cut the cost of each preventable civilian death by 85%, while simultaneously boosting per capita humanitarian spending per capita by 20%. And somehow both of you would regard this as an improvement?

    I'm ashamed when Americans attempt to optimize the wrong metric. Call me a QA weenie if you want, but at least I know something about process engineering!

    >PCL is available on every major printer on the market today - it IS the standard. PostScript is a has-been. Dump it today.

    Huh? I think you've got that backwards.

    PCL requires that most of the "brains" exist on the "computer" side of the "computer/printer" connection. A PCL printer needs less "brains" than a Postscript printer because all the processing is done on the "computer" side of the connection.

    Not to put too fine a point on it, but a PCL printer is to a Postscript printer what a Winmodem is to a hardware modem.

    For printers, the PCL tradeoff made a lot of sense sense when embedded CPUs were (extremely) limited in computational power compared with desktop CPUs. Rather than have your $1500 486-33 sitting idle as it dumps a pile of Postscript code to another $1000 68020 in the printer, I'll use my $1500 desktop CPU to turn my document into PCL that can be parsed by the $1.99 Z80 or whatever's in my $100 PCL printer.

    Now that your $25 disposable cell phone has a 200 MHz core, that tradeoff is no longer a requirement. Embedded systems smart enough to interpret and run Postscript code are no more (and no less) expensive than those capable only of PCL.

    Methinks you've got the PCL/Postscript design tradeoff backwards.

    God, 2004 AD: "Supremely clever dude, existing completely outside of what we perceive as spacetime, may have tweaked an m-brane collision (the math for which only a few hundred of us on the planet can even begin to understand) that resulted in the setting of a few universal constants for the physics engine and the creation of a little bubble of spacetime. Sat back and watched the resulting fireworks for 13.8 billion years to see if sentient life would evolve in a little pocket of it and recognize Him."

    How about a tinfoil hat for one side of the asteroid?

    Unfortunately, the Yarkovsky Effect - deflecting an asteroid by differentially heating parts of its surface - is likely to be too small to save us. Deflection of a rock comparable in size to 2004MN4, namely 6489 Golevka, was observed as 15km in 12 years of observation. Depending on the eventual impact point (if any) of 2004MN4, we may have to deflect it by thousands of kilometers.

    Yes, you'll probably get much more deflection by wrapping half the rock in mylar (and/or dusting the other half of it with soot), rather than relying on the natural effect observed on 6489 Golevka, but we don't know enough about 2004MN4 (albedo/mass) to guess yet.
