  1. Re:Wait, what?! on Largest US Power Storing Solar Array Goes Live · · Score: 1

    http://en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant
    esimated 4 years construction at 3.2BEuro.
    construction started in 2005.

    Current state
    Estimated completion time 2015 estimated cost closer to 9BEuro

    1600MW.

    So if things go well the construction cost and time are good value for money (excluding maintenence, fuel and decommissioning over the lifetime) In reality things are not quite so peachy as 10 years can be a very long time to wait for extra capactiy.

    The 2 billion undoubtedly includes some of the running and maintence costs and initital debt service for a few years. And it is privately funded (just gov guarenteed loans). So the gov isn't out of pocket in anyway unless it fails.

    In the top 4 universities 2 are American and 2 are British (Chose top 4 to be fair as it is an even split)
    Yearly cost Undergrad, postgrad
    MIT average $42000-$44000, $42000-$44000
    Cambridge $26000-$28000, $26000-$28000
    Yale $40000-$42000, $38000-$40000
    UCL $24000-$26000, $28000-$30000

    And for the UK those are the unsubsidised international rates (Domestic rates are significantly less and most people won't pay those as undergrads). So why do the American universities cost SO much more?

    But also remember that most of the rankings like this one count research quite heavily resulting in worse that expected results for pure teaching universities. Even though those specialise in education

  5. Re: H1B working as intended. on Justice Department Slaps IBM Over H-1B Hiring Practices · · Score: 1

    The market for talent is global. But H1B's while not necessarily paid lower than the 'going rate' also do not result pay higher than the going rate thus reducing the pay that everyone (H1B's, locals, contactors etc.) can get.

    H1Bs are not enabling more people to immigrate to the US.

    In this case IBM were specifically targeting foreign nationals so that they could be easily relocated later. I.e. teach them to be a westerner IBM employee then throw them somewhere else in the world so that wherever they end up they can push the IBM way. IBM have been pretty successful at moving jobs around the world. They have managed it by not out-sourcing or off-shoring but by moving whole divisions. (middle management and upper middle management as well). It works well for them and seems to be good for the balance sheets. Is it?

    And they are cute.
    Spiders cannot move thier eyes so move thier bodies, it is quite obvious when they are looking at you. The retina is relativly small for the size of the eye. However they can move the retina and they seem to scan the world by moving it around.

    A number of years ago I saw a film of a jumping spider trying to attack another spider (in a web). after a number of approaches failed the jumping spider dissapeared from the shot only to apear a while later on a twig above and offset wrt the web. Let its self down on a thread and then swung pendulum style towards the other spider until it could grab it.

  8. Re:Makes complete sense on Flies See the World In Slo-Mo, Say Researchers · · Score: 1

    I know. I was using it as an example of how sample rate is the wrong term. The timing differences between signals for each ear are significantly smaller than signal propagation time. However clever differetial processing can handle such small timescales. Yeh it will take you a while to determine the source of the sound as it is a higher level function but the raw signals (as in nerve signals (frequency pulses)) are handled at a much finer granulatrity than would be expected if you just looked at the 'specifications'

  10. Re:Makes complete sense on Flies See the World In Slo-Mo, Say Researchers · · Score: 1

    Humans have a distributed nerous processing system to help with signal speed issues. If you burn your finger your arm will move before the signal has a chance to reach your noggin let alone be processed and interpreted by it. Sample rate is the wrong term. response time is better but still not a great term. Whatever you call it it is variable and at different speeds within a single entity (depending on what the input is). Human stereo hearing is another example. Cross talk between the singnals from your ears can be handled to such a fine degree you can determine the origin of a sound.

    Sort of. The compound eyes never seem to produce an image. Not really enough neural matter there. Most reactions are based on differentials within the eye and between eyes. Finding food does not appear to be a function of the eyes (in flies). In bees it does to a small extent but more so the navigation mechanisms they use. Similar with ants. They follow the trails of scouts to find food. The scouts seem to wander almost randomly.

  23. Re:How is that legal? on Time Reporter "Can't Wait" To Justify Drone Strike On Julian Assange · · Score: 2

    Embassies are not foreign territory. They are treated as such most of the time (hence Ecuadorian laws are used in the Ecuadorian embassy) but they are not.
    The hosting government does not need to do anything special to allow an embassy to be taken. Governments will not do that as is would be very bad foreign policy to do so.
    They could also revoke the embassy’s rights then take the building and occupants. That is internationally legal but you need good justification to not piss people off (and has been done many times) even if all national staff are safely escorted out of the host country.

    Blatantly destroying an embassy in a friendly country would be nuts just to get someone who the US is slightly peeved at. I am not putting it beyond the US at the moment though.

    actually Ijust noticed this in the android api docs for Secure Random
    "Seeding SecureRandom may be insecure
    A seed is an array of bytes used to bootstrap random number generation. To produce cryptographically secure random numbers, both the seed and the algorithm must be secure.

    By default, instances of this class will generate an initial seed using an internal entropy source, such as /dev/urandom. This seed is unpredictable and appropriate for secure use.

    Using the seeded constructor or calling setSeed(byte[]) may completely replace the cryptographically strong default seed causing the instance to return a predictable sequence of numbers unfit for secure use. Due to variations between implementations it is not recommended to use setSeed at all. "

    So it does appear to be a google bug in the default constructor
