    Shara comes to mind, but I might be mixing her up with the goddess/demon in MZB's Darkover series (I know the goddess in those books was Shara, but I seem to remember the names being similar).

  3. Re:More pieces is bad...why? on Stopping Killer Asteroids · · Score: 2
    energy in = energy out. In this case, efficiency doesn't matter as the heat alone from that much stuff burning up in the atmosphere could be an issue, then there's the shockwaves in the air (may not be a problem), then there's the fact that you're not going to get every big piece, and some will be big enough to cause problems when they hit the ground and/or water, and you'll have more than one. Think shotgun.

    Pound it into dust completely? The stuff will wind up suspended in the upper atmosphere: I don't think anybody will be thinking global warming is a problem :). If the fine stuff doesn't wind up in the atmosphere, it might wind up in orbit: "Ooh, look, Earth now has pretty rings! Um... where did the sun go?"

    Mind you, I think global winter would be less of a problem than a big one hitting: gives us more time to pick up the pieces.

  5. Re:Science is not a religion on The Neanderthal's Necklace · · Score: 2
    That only works if your first principles are flawless. Real experimentation will always be necessary, but the amount needed will likely decrease as simulations will make it easier to plan out the real experiments. Going with your CERN example, simulations will make it so you have to do only a few (maybe even one or two) expensive runs to prove or disprove your theory rather than several as the simulations will help you figure out what to look for.

    Sure, that's what scientists try to do now (ie, predict what to look for), but better simulation techniques will just make their predictions more precise and thus easier to prove or disprove with a real experiment.

  6. Re:Wonder what the useful lifetime of these things on New Display Technology to Compete with LCDs? · · Score: 2

    While this is likely true (I only did introductory materials engineering, but it makes sense), some (many? all?) metals have the interesting property that if you leave them long enough after bending, they will `heal' and you'll be able to bend them again. Of course, different metals have differing heal times, with lead and gold being quite fast (hours to days?) and most others being quite long (in the months to years range?).

    This is more for those that don't know :)

    60Hz refresh is ok-ish in places like Australia, New Zealand and anywhere else using 50Hz mains rather than North America's 60Hz. The flicker you see on a monitor is caused by the monitor and the room's lighting interfering with each other and causing beat frequencies: very much like two musical instruments that aren't quite in tune.

    The spin is what stops them from collapsing into an even bigger black hole. The stars in a galaxy are always pulled towards the center of the galaxy but always (except for some unlucky ones) miss the center/each other. WHy did the spin start in the first place? I believe the prevailing theories go for uneven mass distribution and turbulance.

    Not quite true. With a large enough explosion, things will never stop. There are three possible conditions:
    1. The explosion is too small: everything comes back again. If they miss, they orbit each other (circular (special case of ellipse:) or elliptical)
    2. The explosion is just right: everthing is gone forever but eventually stops at infinity. Straight line or parabolic trajectory.
    3. The explosion is too big: everything is gone forever and never stops, not even at infinity. Straight line or hyperbolic trajectory.
    The size of the explosion needed for each case is easy to find from the escape velocity/energy (E=1/2mV^2). For V (velocity due to explosion) < Ve (escape velocity), you get 1; V == Ve, you get 2; V > Ve, you get 3. The main difference between cases 2 and 3 is the velocity in case 2 has a zero asymptote while in 3 it has a non-zero asymptote.

    A 1ms delay for a packet does not equate to 1000 packets per second. It just means that your (eg) 20ms packet (50 packets per second seems reasnable) comes out 21ms after the first sample went in rather than 20ms.

    As an example, look at ppp: your ping time over a 56k modem to your ppp server is going to be around 100ms but it takes about 250ms for a 1500 byte packet to get transfered which is why modem users often see around 200-300ms ping times when playing online games (depending on the size of the packets). Even with that 100ms delay, you will still get about 4 packets per second even though 350*4=1400 (or 325*4=1300 if you're going to split the ping).

  20. Re:Finally, ABI stabilization. Now about optimizat on GCC 3.2 Released · · Score: 2
    I guarantee there are aliasing bugs in Quake (whether they're still there in Twilight is another matter). How am I so certain? I fixed several in QuakeForge (another Quake project). I'm beginning to think there are some more due to some weird issues we're getting with our quakeworld server where everybody is complaining of disappearing entities (ie, it doesn't matter which client they use).

    While I agree with others that "we didn't get squat" isn't accurate, there's a darn good reason "we" (I'm Canadian, but the whole world would have benefitted in the long run) didn't get as much as we could have out of going to the moon: only 12 people stepped foot on the moon; 30 years ago; nobody's touched it since.

    Think of the deep space observatory that could be run on the far side of the moon, shielded from Earth's radio noise. Think of the oxygen and aluminum (and possibly water due to either possible water supplies on Luna or reacting the extracted oxygen with hydrogen from the sun (assuming enough H can be collected from the solar wind)) that could have been mined for supplying the space station with at a much reduced (long term). Think of the deep space probes that could have been launched from Luna at a much reduced cost again (shallower gravity well, further out Earth's well, and possibly with a slingshot boost due to Luna's orbit).

    The possibilities don't stop there, just my train of thought :) I really do wonder where we would have been now if Luna had been `colonized' back in the 70's or 80's (maybe 90's due to more tech advances being needed).
