    If you do that, it performs slightly better. But - there is still an astonishing amount of certificate changes of big sites, where the signing CA changes too.

    See this paper for a few examples.

    Because it does not work very well. If you look at actual sites (especially bigger ones like google, or cdn-using sites), using multiple certificates for the same hostname is pretty usual...

    Like it was/is sometimes used in ham-radio packet radio or in satellite communitation.

    http://en.wikipedia.org/wiki/Demand_Assigned_Multiple_Access

    The wikipedia description actually makes it sound a bit more complex than it actually it. In packet-radio DAMA simply meant that the central station polled each node regularly and asked it if it has queued requests. The only thing a client was allowed to send without asking back was the "I am a new client"-message.

  5. Re:FUD article on Could the US Phase Out Nuclear Power? · · Score: 1

    Just to disappoint you...

    Germany has just shut down 8 of its 17 nuclear reactors. It still does not need to import energy (in the last years Germany exported a massive amount of energy to other countries). Before the shutdown, Germany produced about 20% of its energy from nuclear and abount 17% from renewable energy sources (see wikipedia)

    After the shutdown, Germany probably produces more power from renewable as from nuclear energy...

  6. Re:Longer Answer: on Could the US Phase Out Nuclear Power? · · Score: 1

    Nope, they will not.

    Since 2004 France (which has more than 40 nuclear reactors) has imported power from Germany, not the other way round.

    Germany still has a (admittedly small) surplus, even after powering down 8 nuclear reactors at once. And the dependence on Germany on nuclear power is not very great -- Germany gets approximately the same amount of power from wind energy as from nuclear energy.

    So, replacing the nuclear plats without depending on outside power imports is not impossible...

    Well, no, it does not necessary.

    Convergent encryption is a widely used technique, where a file is encrypted with it's hash value.
    Thus identical files are always are encrypted with the identical key.

    However yes - this breaks privacy for files which are saved by several users.

    Or, if you want to wait for your vendor patch, set vm.mmap_min_addr manually, if it hasn't been set by your vendor already - the only distribution I have where this is necessary is debian.

    You can either do
    # sysctl -w vm.mmap_min_addr = 65536
    and redo that every reboot or do

    # echo "vm.mmap_min_addr = 65536" > /etc/sysctl.d/mmap_min_addr.conf
    # /etc/init.d/procps restart
    and be done with it.

    It says that it was only fixed " in the upcoming 2.6.32 release candidate of the Linux kernel" - hence everything before that is vulnerable.

    But the bug is not exploitable on ubuntu, because they set vm.mmap_min_addr > 0 by default.

    Nope, it is a new one, but the same old bugfix still works.

    Just type sysctl -w vm.mmap_min_addr=4096 in your box (or any other number > 0) and you are safe.

  14. Clarification of German law on cp etc. on Germans Pursuing Kiddie Porn In Second Life · · Score: 1

    Ok, as there seem to be some open questions about the german law governing child pornography, I will try to explain it a little bit... Child pornography is a criminal offence according to 184b of the german penal code (Strafgesetzbuch).

    According to 184b Stgb. it is forbidden to distribute, display, present or make accessible child pornography (punishable by up to 5 years of prison).

    It is also forbidden to procure or to own child pornography (punishable by up to two years of prison). You don't even have to be aware that you own child pornography to be punished for it. There have been cases of people being convicted fo owning child pornography that have tried to fight agains it.

    Child pornography includes everything that deals with the abuse of children (anyone under the age of 14 in germany); that means that it is forbidden for underage avatars to have sex with each other in germany (and it doesn't matter if the people behind it are adult or not). Stories of children (under 14) having sex are also forbidden.

    Linden labs has to take actions against this, otherwise they might be punished themselves (for distributing and making accessible child pornography). And germany is an important market for linden labs; there are more germans in second life than u.s. residents (about 209,000 germany logged in to SL in april 2007 compared to 207,000 americans).

    Furry sex is also forbidden in germany; according to 184a Stgb. the distribution, exhibition, etc. of pornography with animals is forbidden (it doesn't matter if they are virtual or not; it doesn't even matter if it are real animals or only fantasy ones). But it is not forbidden to own animal or to procure animal porn. But linden labs might be punished for making it accessible.
