  1. Re:Modded out on SpaceShipThree to be Orbital Spacecraft · · Score: 1

    I think political correctness is way of what is in the parent post. Just hurting other people based on sexual preference, looks or religion is not done. If it was not that, but just a straight flame at another poster in dirty wording (but aimed at one person, not at a group), I would not care, for that the moderation system works good.

  2. Re:Another Idea. on SpaceShipThree to be Orbital Spacecraft · · Score: 1

    If in space engineering improves, your idea might be possible. You can then utilize the remaining space/weight in a launch craft, like what is now done by piggybacking micro satellites designed by students as research projects.

    At this moment though putting something together in space is a gamble, mostly to be avoided. Handling tools in space is tricky (no gravity, no friction so action is reaction is images of things floating of into the sun).

  3. Re:Why SpaceShip[One|Two|Three] will not reach orb on SpaceShipThree to be Orbital Spacecraft · · Score: 3, Informative

    It is a big fuel saver. The use of the fuel is non-linear, So when you can save some fuel by having a higher starting point with less drag, it also has a non-linear saving as result.
    Just calculate the needed potential energy to lift the crafts total mass for 10km up in the air, and you know what basic savings you get.

    I also can not seem to find an image of a rocket trajectory, so a description will have to suffice: The first few kilometer the trajectory is as straight up as possible. The trajectory in the densist air layers is the shortest possible. Since speeding up in that part is costly (drag=speed^2), the speed is kept down, in multistage rockets by coasting, or with solid fuel rockets by designing the thrust in such a way that you do not spend to much fuel on speed. Once the air density is low enough (less drag), you will speed up again, and adjust the trajectoy to get to escape velocity. For a decaying orbital trajectory, you do not necessarily need escape velocity, you just need to be able to make it around the earth like one time. So going orbital is also still pretty free in interpretation and goal.
    New designs for suborbital planes with ramjets almost all use this design principle for this reason (and they need to get up to speed to make the ramjet work).

    The main problem stays though that the design is complex, the take-off of a combined craft like this is slow, and the payload the combined craft can take is low, not higher than current rocket techniques if you really want to get into orbit (Imagine the shuttle+fueltank minus thrusters being lifted to sufficient height)

    Why the body cavity search. If it blows in space, nobody will know why anyway. Or does it have to do with Australian customs?

  6. Modded out on SpaceShipThree to be Orbital Spacecraft · · Score: 0, Offtopic

    It is modded out already (as far as possible with the moderation system), the bad part is, that this person who posts that message has now posted it several times, thus making you, me and others look at that nonsense and most likely hurtfull text several times now.
    Search engines will also pick it up, that way spreading it even further.

    A change in the moderation system would be nice, but writing this down will probably break the fabric of the universe:
    I, a regular /. visitor and contributor (ok, all my contributions are denied sofar), ask /. to CENSOR /. for certain messages, and block access for certain IP addresses which post offtopic texts with highly likely hurtfull content.
    Proposal to get a message offline is: Introduce an extra modifier hurtfull/discriminative. Once a message is marked that way once only, a message will be generated at one of the maintainers. He/she will look at it and disable/remove the message if it a valid moderation in that category. If is not a valid moderation in that category, extra hurtfull moderations will not produce extra messages.

    I know this is way offtopic, just as the parent is, but something needs to be done about the grandparent messages.

    Best regards,

    Well, orbital does not by definition be in space. For his spacehotel ideas: Yes, you have to go in space, but for just fly around the globe in a rapidly decaying orbit, you do not have to go very high and reach super high speeds. And lower speed is lower heat. So hopefully that will save him from having to use tiles.

    And assuming that they start on the ground. The lift they get by the "white knight" is a very big saver on fuel and engine weight since they do not have to go through the first layers of the atmosphere.

  12. The list of articial nature on Robot Bat With Echolocation · · Score: 1, Funny

    With the demise of real nature, and cutting cost on the remaining nature, the following proposals are being made:
    In cities replace real gras with fake gras, same for flowers and trees (who cares that the real versions produce oxygen, and reduce polution in several ways)
    Since plastic trees and flowers are less likely to sustain life, other forms of life will be replaced too. The research sofar has the following:
    Robotic dog
    Robotic cat
    Head of bat (hey, Do you want to have them flying around?)
    Some fake cockroaches
    For on the benches in the parks, which without real nature will be less attractive anyway, all dirt which is now cleaned up by nature, will stay around, we will have cute looking japanese femal robots able to wave at you when you drive by, making it look very lively.

  15. Re:Google might launch tomorrow on Google Instant Messenger Coming Really (or Not?) · · Score: 1

    Let me refrase: The only way to play with the big boys is not to play the same game, so by making it cross platform, you will get more support from a community which have been very supportive already. Everytime though they turn out a single platform product, the reasons for keep using google when they for example are being outrun in search for a while will get smaller. They will not be the first to have a huge downfall (Remember altavista?).

    Google does really owe a lot to the community, they actually used that in a recent speech. They run linux and not windows because being google in the start they could not afford to run windows in several ways (maintenance, setup & licence fees). Without community there would be no Google. And yes, BSD is also community.

  16. Google might launch tomorrow on Google Instant Messenger Coming Really (or Not?) · · Score: 4, Insightful

    And I just run into somebody on the street proclaiming that the world might fall to pieces tomorrow (actually claiming that the world will end tomorrow, and then asking for a donation. I failed to see the short term use of that donation, so I just wished him luck).

    Anyway: Come back tomorrow and see if google really launched a IM. And if they do, then please not in google earth style or any other google windows only products. If they really want to play along with the big boys, they should make it crossplatform. It is what they owe their current status to!

  18. Re:how to wipe pdas clean... on PDA Security, the Next Big Hurdle for IT? · · Score: 1

    There are enough utilities to wipe disks clean like for example zerodisk. Or if you want to destroy just one file use shred. So adding this kind of functionality is not too tough. The point is more what happens when the device is out of reach. I think the best solution is to have a stateless device, so no data present when you do not have a correct connection. The question is if the device still is usefull for the goverment at that moment.

    They mention some proprietary parts in the article, plus the NSA does not have to keep itself to the commercial laws concerning encryption.

    This explains everything, so a lot of projects should pay, but at this moment they are just trying to make up for the cost of protecting the trademark by going after big players (>1mln US$).

    I only disagree with one thing: A trademark does not garantee quality at the moment of rewarding the trademark. You only know that the product sucked when the trademark is revoked because of bad quality.
