  1. The equations you need are... on The Mathematics of a Trip to Mars? · · Score: 1
    (1) F = G*m1*m2/r^2

    expresses the gravitational force on a body

    (2) F = m*a

    expresses how the acceleration on a body depends on the sum of forces acting on it.

    You can work out the path of a space probe by iterating these equations over short periods of time (to find out how short, keep making them smaller until the answers don't change).

    To answer the question "what starting velocity do I need to get from eath to mars?" is more complex, but probably no more so than a few hundred lines of Python.

  2. According to creationists... on Remember When Elephants Had Tusks? · · Score: 1

    The reason for the lack of tusks isn't evolution, it is evidence of an "Intelligent Designer".

  3. My fucking taxes on The Virtual Planet Explorer · · Score: 1

    This project was funded with my fucking taxes so why should I have to pay another E 10,000 for it? I've already paid once. It should be released on an open source license, as should all publicly-developed software.

  4. Police forces should be abolished on Open Source Molecules · · Score: 2, Informative

    Obviously the government shouldn't have a police force, since that takes businress away from private security companies. Nor should the government run schools, since that takes money away rom private education. And having an army is unfair competition for mercenaries.

  5. More detail here... on Open Source Self-Replicating Robot · · Score: 1

    There's more detail here or here.

  6. Silly Canadians on U.S. Rejects Canadian Rejection of DMCA · · Score: 1

    Silly Canadians, believing they are an independent country that can make their own laws -- don't they know that under NAFTA, they have to do what they USA tells them to?

  7. Then parliament should sack the commission on EU Commission Declines Patent Debate Restart · · Score: 3, Insightful
    Because they don't think the parliament will fire them over just this, and that is the only option of sanction the European Parliament has.

    Since the unelected European Commission insists on treating democracy with open comtempt, the European Parliament should sack them.

  8. Re:*Bzzt* Wrong on Who's Really Responsible In Online Banking Fraud? · · Score: 1
    As was pointed out before, a bank is expected to be a bit more security minded than that.

    I agree, a bank should be security minded. The bank controls its own computer system, not its customers. So the bank should make sure its own computer system is secure.

    The bank shouldn't attempt to control its customers' computers (if my bank wanted to control what software I used on my PC, I wouldn't be their customer any more). Be cause the bank can't control the user's comupter, the bank isn't responsible for it (no responsibility without authority). The bank should ensure its software uses sensible protocols, such as https, and allow the user to connect with whatever software he wants.

    The bank might recommend its users use certain software, e.g. a particular operating system or web browser. If it does this, it obviously shouldn't recommend anything that has a well-reserved reputation for insecurity! And it certainly should not require that its customers use any such system.

  9. Re:Did the businessman use MS Windows? on Who's Really Responsible In Online Banking Fraud? · · Score: 1
    What if his bank will only let him access their website with IE?

    Then it is the bank's fault, and the bank should refund him all his losses. The idiot PHB responsible for the IE-only policy should be sacked.

  10. Did the businessman use MS Windows? on Who's Really Responsible In Online Banking Fraud? · · Score: 2, Insightful

    If the victim in this case used Microsoft Windows, with all its well-know and well-publicised security flaws, he only has himself to blame.

  11. Re:Of course they should! on Should Taxpayers Pay Twice For Weather Data? · · Score: 1

    Who's the idiot who doesn't know the difference between sarcasm and trollery? If someone is meta-moderating this, mark the moderation down please.

  12. Of course they should! on Should Taxpayers Pay Twice For Weather Data? · · Score: 0, Troll

    Of course taxpayers should be forced to pay twice! America represents government of the corporations, by the corporations, for the corporations. The people don't get a look-in.

    On a similar note DRM schemes and region coding are obviously good things, because corporations want them.

    And Linux is a cancer invented by communists. Bill Gates says so, so it must be true.

  13. Don't buy from Belkin on Belkin Offering Pre-802.11N Products · · Score: 2, Interesting

    Remember, these are the guys who tried to sell you deliberately non-working kit.

    I don't buy from Belkin. I hope you choose not to, too.

  14. Some of this money should go to Linux on German Court Sets Copyright Tax on New PCs · · Score: 1

    People who buy these new PCs will be putting copyrihhted material onto them. (Since all new material is automatically copyrighted, this must be so). Onve common form of copyrighted material is open source software, which is frequently put on PCs. Therefore linux and other open source projects should get a share of this money.

  15. Re:Animals are not humans on Re-Pet a Reality · · Score: 1
    Cloning animals is one thing. I personally don't think we'll EVER be able to clone a human.

    Of course not. The proof of this is the non-existence of human identical twins, which if they existed (and they do not -- don't believe the lies of the cloning industry) would be clones.

  16. Re:Security/Privacy issues on Firefox vs. SP2's IE? · · Score: 1
    This analogy is unfortunately all too accurate. Not only does the rest of the insured/tax-paying population have to shoulder the health-care costs of smokers

    Actually, smokers have less halth care costs over their lifetimes than non-smokers, because they die earlier. And that's before you factor in the savings to the taxpayer on reduced old age pensions.

  17. Have you read the samll print? on Paint.NET: The Anti-GIMP? · · Score: 1

    Have you read the small print in the license, where it says:

    By using Paint.NET, you agree never to use GIMP, Linux or any software licensed under the GNU General Public License.
    You further agree that your firstborn son shall be the property of Microsoft Corp.
  18. If their new pet behaves differently... on Re-Pet a Reality · · Score: 1

    If their new pet behaves differently from their old one, will people ask for their money back?

  19. Re:A little too far? on Revising the GPL · · Score: 1

    the hardware we are producing will only run the software we create.

    That's fine, if people create their own software. But if people, instead of creating their own, use GPL'ed software, they should obey the GPL. (If they don't like the terms of the GPL -- don't use it).

    The idea behind the GPL is that the software will always remain free. The FSF defines free to include "The freedom to study how the program works, and adapt it to your needs".

    But TiVo use a "trick" to prevent people adapting the software. This is within the letter of the GPL, but against the spirit of it. So the FSF are amending the GPL so its letter is closer to its spirit.

  20. Re:A little too far? on Revising the GPL · · Score: 1

    I say here's my code, feel free to read it, to tell me what you think might need updating, and feel free to make your own, but my hardware will only run my version of the sofware.

    But once you sell your hardware, it isn't your hardware any more, it's whoever you sold it to's hardware.

    If TiVo don't want people to modify the software in their TiVo boxes, they shouldn't have sold said boxes to people. Ditto with Microsoft and the XBOX, and Sony and the PS2.

  21. I hope pond slime like Darl lost tons of money on SCO Shares Plunge, Canopy Management Change · · Score: 1

    I hope that lots of pond slime like Darl McBride lost tons of money on this, but I suspect slimy Darl sold his shares to some mug some time ago.

  22. American leaders should grow up on EU Presses Ahead With Galileo GPS System · · Score: 1
    "freedom fries" [...] made it very clear to all Europe that they're not dealing with adults.

    The USA will have to get used to the EU: its economy now surpasses the USA's, it continues its Borg-like growth, and it's starting to find its feet internationally.

  23. Of course it is dual use on EU Presses Ahead With Galileo GPS System · · Score: 1

    Some people have criticised Galileo saying it is "dual use", i.e. it can be used for military applications.

    But that's a nonsensical argument; all general-purpose technology has potential military uses, so if we accept the argument that Europe shouldn't develop Galileo because it is dual uise, then Europe shouldn't develop any advanced technology at all.

    BTW, Israel is also a partner in Galileo; is Israel also part of a sinister evil plot to attack the USA?

  24. USA needs to stard treating Europe as equal on EU Presses Ahead With Galileo GPS System · · Score: 4, Insightful
    Why should we, the US, be forced put other nation's interests above our own?

    The USA shouldn't; and nor should Europe be forced to put the USA's interests above its own

  25. It's "piqued", you illiterate moron on A Review of Ubuntu Warty Release · · Score: 0, Redundant

    Recent news about Ubuntu had peaked my interest (my emphasis)

    It's piqued, idiot. When is Slashdot going to employ literate editors?
