  1. Re:Should be interesting on UN Climate Report Fails To Capture Arctic Ice: MIT · · Score: 1

    Cutting carbon emissions doesn't mean we can't have cars. It means that cars need to be more energy efficient in the near future and run on energy not derived from fossil fuels in several decades. Reducing carbon dioxide emissions doesn't mean doing without. It seems that most people who don't want to reduce carbon dioxide emissions really just don't want to lower their standard of living. Fortunately, we can reduce carbon dioxide emissions significantly and keep our standard of living.

    And save money at the same time as reducing resource usage.

    The whole Java *or* Python discussion is irrelevant. You can use Jython, and take advantage of all the Python and Java libraries.

    We must GPS space!

    If only we had satellites there, then we might be able to triangulate just like on earth!

    Here is an interesting talk on the N.Korean nuclear program by a former director of the Manhattan project: http://www.youtube.com/watch?v=VIdRSl7Dc88

    His conclusions regarding the reasons of the developments, nuclear security and how to reach a diplomatic solution are highly interesting.

  6. Re:files on Real-Time Text Over Jabber/XMPP/Google Talk · · Score: 1

    Sending files in-band can fail/get stuck as GP said; also it is often capped by administrators. In my peer-to-peer filesharing application, dubbed Jake [sf.net], I use XMPP to negotiate a ICE/STUN peer-to-peer connection. If that fails, there is always the in-band method to fall back to. (The backend seems to work decently, the GUI and testing needs work though)

    The jingle protocol is supposed to be for XMPP what ICE/SIP is for VoIP, but there are only few implementations.

  7. Re:Nothing has changed on Dropbox Releases Revised TOS · · Score: 1

    I am working on a server-less peer-to-peer filesharing application, dubbed Jake. Quite interesting technology stack (XMPP, ICE/STUN, AES-encryption, RSync). As someone stated below, why involve/trust a third party?

    There is also http://retroshare.sf.net/

    On a serious note, the Linux distribution choosers/selectors out there can answer your and similar questions.

  9. Re:None of this (except the passwords)... on Hacker Exposes Parts of Florida's Voting Database · · Score: 2

    How is this leak related to the poll? Its just the poll workers -- a separate system from the voting machines -- so how does this affect voting security at all?

    Of course I agree that voting must be secret, integer, valid, transparent, accurate and reliable. Better use paper there, to allow independent verification.

  15. Re:Regression testing on Dropbox Password Goof Let Any Password Work For 4 Hours · · Score: 4, Funny

    This is why automated regression testing is a best practice. I guess Dropbox don't test their authentication.

    That would be so oldschool. We do agile development now, and the user is the tester once the unit-tests pass.

  17. Re:In addition, the compilation is under the GPL on Court Case To Test GNU GPL · · Score: 1

    To create a compilation, you do need rights to publish each part, but you do not need permission to modify or prepare derivative works.

    This is a rather strange thing to say. If a part of the compilation is under copyright, then the compilation itself is a derivative work.

    No it is not. And this is the whole point of this argument and frequent discussions on license-discuss@opensource.org.

    For the extreme open-source people, anything that uses GPL2, must also be GPL2.
    But that is not true. If you build something, and that does work without a GPL2 library, but can optionally use it, the work does not have to be GPL2. Otherwise all programs on linux would have to be GPL2.
    So if I make a addon for program X that adds a feature that requires a GPL2 library/program, the addon will have to be GPL2, but the program doesn't. Examples of these are also database access layers.

    The distinction between derivative works and independent works is blurry at the moment. And this is what the case is about, as far as TFS goes. So it is good for courts to investigate this line.

    Gold has inherent value. You need it to build useful things like space crafts and (some) electronics, and research in physics. Also, since ancient times it has served as juwelery. https://secure.wikimedia.org/wikipedia/en/wiki/Gold#Use_and_applications

    If you now say that gold doesn't have value without humans giving it value, then I'd have to argue that the word value doesn't have a meaning.

  20. Re:I just used grep -P on How Journalists Data-Mined the Wikileaks Docs · · Score: 4, Insightful

    Worked miracles after I've gotten around the ugly HTML format they use to release all those INFORMATIONS. Still, there was very little new or worthwhile in the heap of those news clips and rumour aggregations. Frankly, the more I grep it, the less it looks like the "largest leak in history", and the more it seems like "the largest controlled release of information" in history.

    / takes off conspiracy theory hat // flame on

    When you use grep you have to know what you grep for. You can not stumble upon a search keyword with grep.
    Clustering allows that, if you let it build the clusters itself. Perhaps you are missing out on the interesting bits.

    This paragraph from TFA sums up their argument:

    The French TV regulatory agency Conseil Supérieur de l’Audiovisuel (CSA) insists the French government is simply upholding its laws. “Why give preference to Facebook, which is worth billions of dollars, when there are many other social networks that are struggling for recognition?” a CSA spokesperson said in a statement. “This would be a distortion of competition. If we allow Facebook and Twitter to be cited on air, it’s opening a Pandora’s Box — other social networks will complain to us saying, ‘why not us?’”

  24. Re:Here we go on Ask Slashdot: Is SHA-512 the Way To Go? · · Score: 1

    SHA-1 can be broken for document hashing. Use SHA-512 there. Also for encryption.
    For password hashing, SHA-1 is sufficient, although there is no harm in using SHA-512. The reason SHA-1 is not broken here is that the hash (or seed) is not known to the attacker so he can not forge a cleartext with the same hash. This is why it is different from document hashing / encryption.
    There is no reason to use MD5 anymore, The SHA-ciphers are superior.
