  1. Re:Not very useful the way it's worded. on Nuclear Rocket Petition On White House Website · · Score: 1

    Nuclear Thermal Rockets can have a higher efficiency than than conventional chemical rockets, but it's not as much as you might think. There's a limitation that to have a higher exhaust velocity in a thermal rocket, the exhaust needs to be hotter. And it can only be so much hotter before your reactor starts becoming molten rather than a solid.

    So have a gaseous reactor.

    And! Again! With the ad hominem insults about OCD! If there was any substance to your claims you wouldn't need to try personal attacks. Windows one-size-will-fit-everyone approach does not mean that Windows package management is any good. Have a look at this for a real package manager, and that's from 1997.

    rpm -v and debsums will get you quite a bit of the way there. Only time I've had to use that in anger was after a "make install" went crazy. There's some debian tool for checking what an install does, but since that does a "before and after" that won't work with crapware. Or the base-os+crap package. Yeah, clean install is always best.

    Why should OS components be treated differently from applications - they are applications themselves. Microsoft got in trouble in court over that with IE. And dozens of processes running that I don't need. Virus-bait crapware. LitePC's embedded 98 on a PC/104 card made for a sweet and user familiar info kiosk. But linux does that much better. Because it's package manager isn't a toy.

    Windows has package management? Oh really? So which package is the MSHTML engine in, so I can rip it out. Oh, and while I'm at it, how about ripping out the entire Win32 subsystem and just leaving a CMD line? Sysinternals can do it. Debian can do it using the package management system. Linux packages *everything* - typically giving granularity of tens of thousands of packages. Windows? Maybe tens, if you're lucky. BTW, I liked the XPlite tool that did give some more package control over the system, is there anything like that for Win7?

    How does the HFT magically know what you were willing to pay? It's really hard to have a reasoned debate when people are attributing ridiculous feats to HFT.

    Imagine two genuine traders, GT1 and GT2. There's an item that GT1 wants to sell and GT2 wants to buy. GT1 is prepared to sell for as little as 21.10, and GT2 is prepared to pay up to 21.20. Past trades have been at 21.17, so GT2 offers 21.15, and the sale occurs. Now add a high frequency trader, HFT.

    • [GT1] Tells exchange, sell for as little as 21.10
    • [HFT] Places buy order with exchange for 21.35
    • [Exchange] Tells HFT "Sold!"
    • [HFT] Tells exchange: "HaHa - only kidding. Cancel it."
    • [HFT] Places buy order with exchange for 21.34
    • [Exchange] Tells HFT "Sold!"
    • [HFT] Tells exchange: "HaHa - only kidding. Cancel it."
    • ...
    • [HFT] Places buy order with exchange for 21.09
    • [Exchange] Tells HFT "NoGo!"
    • [HFT] Now knows that the minimum that GT1 will trade for is 21:10

    Rinse and repeat to find the maximum that GT2 is prepared to pay. Buy from GT1 at their minimum price, and/or sell to GT2 at their maximum, pocket the difference. GT1 has made less than they would have without high frequency trading, and GT2 has spent more that they would have. And GT1 and GT2 are probably your pension funds.
