  1. Re:Actually going down on Data Center Managers Weary of Whittling Cooling Costs · · Score: 1

    Then you want DCIE (Data center infrastructure efficiency). It's the inverse of PUE and it is expressed as a sensible percentage figure where 93% is current state of the art and 100% is perfect efficiency. But PUE is the metric people are using, whether it makes sense or not.

    I don't think it's an US vs European thing. Personally, I've always had trouble with Europen fuel efficiencies, specified in "fuel per distance", because I find it weird to have "lower = better" when comparing efficiencies (and also because of the weird "L/100 km" unit). The American "miles per gallon" is more sensible in comparisons, despite the screwed up base units.

  2. Re:Sounds like it's time for multiple micro-center on Data Center Managers Weary of Whittling Cooling Costs · · Score: 1

    If you spend 1 watt on cooling for every 4 watt of heat (i.e. every 4 watt of computing), you have a PUE of 1.25. Not too bad, but far from state of the art.

    The efficiency of the computers do not impact PUE, since PUE only looks at the power ratio between computing equipment and the rest of the data center (which is primarily cooling).

  3. Re:Awesome on Google and NASA Snap Up D-Wave Quantum Computer · · Score: 3, Insightful

    Except what they obviously intend to use it for - large scale decryption of SSL traffic so the data can be mined by Google (for profit) and the Government (to oppress).

    If that's their intent, they'll be sorely disappointed, since D-Wave's machine has only 512 qubits (where as all new SSL certificates are at least 1024 bits). More importantly, the machine is not a general purpose quantum computer and can't run Shor's algorithm.

    Besides, NSA is already able to break 1024 bit RSA using conventional computing (not to mention the possibility of much cheaper side channel attacks). See e.g. Schneier.

    If we are optimistic, it may be possible to factor a 1024-bit RSA modulus [before 2020] by means of an academic effort on [a] limited scale.

    - Kleinjung et al., 2010, my emphasis

    The same paper gives an estimated difficulty of 2 million CPU years for factoring 1024 bit RSA. Sure, that's about $500 million on Amazon EC2, but the NSA have dedicated data centers, dedicated ASICs, smarter algorithms, and money to burn. Realistically, breaking 1024 bit RSA may be as cheap as $50,000 a pop to the NSA... and remember, they only have to break it once per HTTPS certificate, not once per connection.

    (As for Google, they're already have your email and knows every page you visit that contains a YouTube video, a +1 button, or Google Analytics... Why would they waste time breaking RSA when the sidechannel attacks are cheap and plentiful?)

  4. Re:Prostate cancer on Larry Page's Vocal Cords Are Partially Paralyzed · · Score: 5, Interesting

    Prostate cancer is very common among older men, but it's more often an annoyance than a killer, since people usually die of other causes before the cancer can kill them.

    To quote the doctor treating one of my relatives, it's a cancer you die with, not of.

    The relative 5-year survival rate is nearly 100%. The relative 10-year survival rate is 98%. The 15-year relative survival rate is 93%.

    (US numbers)

    That's why prostate cancer has low priority, compared to e.g. breast cancer, which has a relative 1-year survival rate of 96%, and 85% for 5 years (UK numbers).

  5. Re:Dont try it at home. on Box With Hidden Camera Travels Through the Mail · · Score: 2

    I don't think this was the US Postal Service.

    Correct. This is the Danish postal service.

    To put things in perspective: Shortly after September 11, 2001, a friend of mine figured it might be a funny joke to send me a "fake anthrax letter" though the mail. When the flour leaked from the envelope during shipping, the entire post office was shut down and evacuated, and my friend was arrested in the middle of the night, prosecuted... and cleared of all charges. Because, y'know, it was just flour. No harm, no foul.

    So feel free to try this at home, if you live in Denmark.

    The Rights Alliance is in effect threatening a political party to a government. Any obligations Sweden has to that organizations hosting country, could become null and void as a result.

    The Rights Alliance (Rättighetsalliansen) is a Swedish organization, with sister organizations in other countries (e.g. RettighedsAlliancen in Denmark).

    You must realize that Sweden's obligations to the USA trumps Sweden's obligations to its own population.

  14. Ways around TPB blocks on Pirate Bay Documentary Film Now Available On TPB · · Score: 5, Informative

    First method: Try a Pirate Bay proxy: http://thepiratebay.se/, http://malaysiabay.org/, many more

    Second method: Several ISPs use simple DNS blocking, so try Google Public DNS. (This doesn't apply to OP, but may help others.) On Windows, you can use the following command to see if it might work, without changing your DNS: nslookup thepiratebay.org 8.8.8.8 (the IP right now should be 194.71.107.50).

    Third method: Use Google Cache to find the magnet-link:

    1. Do a site:thepiratebay.se Google search for the torrent.
    2. Click the Preview (>>) arrow next to your result, and click the Cached link.
    3. Click "Text Only" version if the page fails to load.
    4. Finally, click the magnet link.

    If the "Cached" link is missing from the Google search result, click on the search result, then copy the URL (the real URL, not the Google redirect URL), prepend "http://webcache.googleusercontent.com/search?q=cache:" to the URL. (example)

  17. Re:Undisclosed new feature on Python 3.3.0 Released · · Score: 3, Informative

    In case anyone is wondering, many programs should perform better under Python 3.3 than under 3.2, due to the new way of storing Unicode strings:

    The memory usage of Python 3.3 is two to three times smaller than Python 3.2, and a little bit better than Python 2.7, on a Django benchmark.

    Benchmarks that focus on certain types of string-operations have seen slowdowns, but real-world applications (such as Django web applications) should benefit from this change. (And real-world applications that perform intensive and performance critical string manipulations should use PyPy.)

  19. Interesting paper on Your Moral Compass Is Reversible · · Score: 1

    I recommend skimming the paper (second link in TFS), it's short and quite readable. At the very least, check out the provided sample of successful manipulations (PDF; the notation is explained on page 2).

    Highlights include:

    Our intuition that abstract principles would involve more moderate attitudes, and engender less detection was not supported by the data.

    The more the participants agreed or disagreed with a statement, the more likely they were to correct the manipulation.

    But:

    The overall rating of the non-detected manipulated trials was notably high. Using a 9-point scale, the average rating was 2.8 or 7.2 depending on the direction of the rating, which means that the average ‘distance’ being manipulated when a statement was reversed was 4.4 units on the scale. This is evidence that the participants cared about the issues involved, and expressed seemingly polarized opinions about the manipulated issues they failed to detect.

    Of course, serious multiple choice questionnaires often repeat the same questions with a different wording each time (or with a reversed scale), precisely to limit issues with bad self-reporting. It would be interesting to see if there's a correlation between consistent replies to differently worded versions of the same question, and ability to detect manipulations like in this study. If so, multiple-choice might be a useful tool after all.
