  1. Evil doer? on Google's Satellites Could Soon See Your Face From Space · · Score: 0

    The company whose boss said I should not expect privacy on Internet will soon have satellites. What could go wrong?

    Indeed with 25cm resolution they cannot recognize people, but they can still track their movements. And combined with data from smartphones, identifying someone gets easier.

  2. Re:Switch off servers? on How Facebook Is Saving Power By 10-15% Through Better Load Balancing · · Score: 1

    it's silly to talk about how factor B might overwhelm factor A when you don't have numbers for factor B.

    Nor for factor A!

  3. Re:Switch off servers? on How Facebook Is Saving Power By 10-15% Through Better Load Balancing · · Score: 2

    I see the value of having a pool of idle servers ready for request peaks. But the graphs in TFA shows they have huge daily variations, hence it could make sense to switch off a fraction of idle servers.

  4. Switch off servers? on How Facebook Is Saving Power By 10-15% Through Better Load Balancing · · Score: 2

    TFA is vague on that point: do they switch off some server during idle hours?

    Such a practice seems good for power consumption, but we have to account the fact that switching on and off shortens hardware lifetime: it creates temperature stress, and we all know that electronics most often die at power on time. Hence what looks like a power saving may hide bigger costs (either financial or environmental) for hardware replacement.

  5. Keys on Facebook Acquires Server-Focused Security Startup · · Score: 1

    They encrypt inside memory, but with what keys? How easily accessible are they?

    The usual tradeoff here is choosing between something that can reboot unattended, but with private key easily accessible, or something that need a password to be entered on restart to decipher the private key

  6. Re:Just use OpenBSD. It's the sensible option. on Facebook Acquires Server-Focused Security Startup · · Score: 4, Insightful

    OpenBSD is security. Security is OpenBSD

    If you think that choosing OpenBSD will magically produce secure setups, you are doomed.

    While I acknowledge valuable security-related work in OpenBSD, a moto such as "Only two remote holes in the default install, in a heck of a long time!" is harmful PR speak. Who use an OS as in the default install, without touching any settings? Just configuring the network push you out of default install (and you win two more remotely-exploitable holes in DNS resolvers).

    And we could also speak about the numerous "reliability fixes" that are often really security fixes you should install to remain secure.

  7. Not hot stuff on The Hidden Cost of Your New Xfinity Router · · Score: 1

    In France, all major operators have been offering for years a public WiFi service, using their customer's modems.

    The feature was pioneered by an operator called Free (with its well known "Freebox" Linux-based modem), and others had to offer the same. Free may buy T-mobile, which should seriously push Comcast to fix its problem.

  8. Dependencies on MIT Considers Whether Courses Are Outdated · · Score: 1

    That is so nice! Students will enjoy learning quantum mechanic or general relativity without having to deal with petty calculus course first. Oh wait...

  9. Another leaker on Edward Snowden Is Not Alone: US Gov't Seeks Another Leaker · · Score: 1

    There is another leaker, except if they failed to revoke all Snowden's accesses.

    But I could not seriously imagine such ridiculous outcome.

  10. Re:They did not hack it on Least Secure Cars Revealed At Black Hat · · Score: 1

    Here's the difference - we have firewalls on the Internet.

    Which explains why web site are never hacked, and why it happens everyday in cars.

    Oh, wait....

  11. Re:Secret for how long? on "Secret Serum" Used To Treat Americans With Ebola · · Score: 1

    it was untested!

    Given that Ebola has 9 chances out of 10 to kill you, I suspect you would bet on the untested drug.

  12. Re:Secret for how long? on "Secret Serum" Used To Treat Americans With Ebola · · Score: 1

    How to explain it was not sent to Africa to help? The only explanation is that the drug is reserved to population that will pay enough for it.

    I could not sleep at night if I made such an investment.

  13. In Russia, government controls corporations on Putin Government Moves To Take Control of Russia's largest space company Energia · · Score: 1

    In Russia, government controls corporations. In USA, it is the other way around.

  14. Secret for how long? on "Secret Serum" Used To Treat Americans With Ebola · · Score: 0

    So US had an Ebola cure waiting for US patients? For how long had this being available, and why was it kept secret?

  15. They did not hack it on Least Secure Cars Revealed At Black Hat · · Score: 5, Interesting

    They did not hack anything, this is just speculation based on documentation. BlackHat used to offer more serious stuff.

  16. Disgusting title on The High-Tech Warfare Behind the Israel - Hamas Conflict · · Score: 1

    I know that will be bad for my karma but I find this stories' title disgusting.

    Indeed there is a war between Israel and Hamas, but at the same time, there is the genocide of Palestinian People by Israel. Most of the ones who die are not Hamas fighters. Their only crime was to live in a territory Israel considers its own. Reducing the conflict to the fight between Israel and Hamas is a petty trick to hide the genocide.

  17. Weak evidence on Ancient Skulls Show Civilization Rose As Testosterone Fell · · Score: 2

    While I find interesting the idea that lesser testosterone is required for cooperation, my opinion is that the path to that conclusion is rather weak.

    They studied testosterone-induced strong features in skulls, observed they vanished as cooperation raised, and concluded that testosterone must have lowered as cooperation increased.

    But correlation is not causation. Another explanation could be that as cooperation increased, fights decreased, and hence the need for strong skull features.Testosterone could have remained at steady level while its effect on skulls lowered.

    No I do not. Will you enlighten me?

  19. Dig? on NASA Announces Mars 2020 Rover Payload · · Score: 1

    No tool to dig the ground? If there is life on Mars it is probably below the surface.

  20. Until the last bitcoin on Inside BitFury's 20 Megawatt Bitcoin Mine · · Score: 1

    What will they do with all that computing power once they will have mined the last bitcoin? I wonder if such setup could be crack and steal existing bitcoins.

  21. Strategy on HP Gives OpenVMS New Life and Path To X86 Port · · Score: 3, Insightful

    Declare a platform dead one year, support it again the next year once customers had time to think about migrating away. Product strategist at HP seems to be a very nice job.

  22. Revoked license on The Problems With Drug Testing · · Score: 1

    The easy way for a doctor to have his license revoked it going outside of mainstream medicine. Reading too much medicine research papers can lead to such situation, and it seems a perfect fit to run human drug trials.

  23. smart cards on Ask Slashdot: Open Hardware/Software-Based Security Token? · · Score: 1

    There are smart cards at affordable price. The biggest problem is to find some that can run without a binary blob driver (would you trust it?).

  24. Proof on seL4 Verified Microkernel Now Open Source · · Score: 2

    While proved software is much better than unproved software, this is not the end of security holes: The proof assumes hardware and compiler behave as specified, which lets a lot of attack surface.

    At least it raises the bar much higher.

  25. Re:Not so bad on Satellite Images Show Russians Shelling Ukraine · · Score: 1

    Well, they moved corpses because of putrefaction (it is summer there), and because dogs and foxes were eating them. That seems quite reasonable.
