  1. Re: How Were All of the Last Predictions? on Could Collapsing Antarctic Glaciers Raise Sea Levels Sooner Than Expected? (salon.com) · · Score: 4, Informative

    The Earth's ocean surface is about 360 million square kilometres. Multiply that by 11 metres, and you have about 4 trillion cubic metres of water, or 4 trillion metric tonnes = 4 quadrillion kilograms. It takes about 64 megajoules to get 1 kg of mass up to the Earth's escape velocity. So, you'd need 256 sextillion joules of energy, just to get that much water off the planet. That's more than twice the amount of energy the USA consumes in a year. And that doesn't consider the efficiencies involved in the technology you use to move the water, or the effects on climate that would result from doing it. Possible? Perhaps. Practical? No way. Better to find a way to stay where we are, or find water that is on Mars already.

    I made a mistake. 360 million square kilometres is 360 trillion square metres. Multiply that by 11 metres, and you have about 4 quadrillion cubic metres, not 4 trillion. So you would need 256 septillion joules of energy, not 256 sextillion. That's more that two thousand times the energy used by the USA in a year. And again, that doesn't take (in)efficiencies into account, or the effect on the Earth's climate that kind of terra-un-forming would have. So, either we make our stand on Earth, or wait for Superman to show up and help us move to Mars.

    Carbon emissions won't continue at their current clip indefinitely, since the green revolution will displace our industrial-revolution based fuel sources.

    That won't be enough. Reducing carbon emissions is important, but we also have to reduce the CO2 that is already in the atmosphere.

    Also, any amount of terrain we lose will be dwarfed by the terrain gained from Antarctica, no longer covered in 3 miles of ice.

    So, rising sea levels will cause devastation to major coastal cities all over the world, but we don't need to worry because we can move to Antarctica??

    Then, theres the need to take water off earth. Are we going to colonize the moon, Mars? Thats going to take terraforming on a planetary scale, and 11 meters of ocean-depth seems like a good start.

    Okay, I didn't think you could top your Antarctica scheme for silliness. Boy, was I wrong. Do you have any idea how much energy it would take to move eleven metres of our ocean from Earth to Mars? The Earth's ocean surface is about 360 million square kilometres.

  3. I thought perhaps it might be Intel's ICC compiler doing a better job of optimizing for Intel CPUs than GCC does. If that were true, and the distro is compiled with it, then that could explain the performance differences.

    But now I doubt that because: (a) what I can find on compiler benchmarks indicates that GCC and ICC are about on par with each other; and (b) Clear Linux has GCC selected as the default anyway.

    I wonder if some crucial parts of the system were re-coded to work better on Intel systems, at the expense of cross-compatibility (or AMD products.) That might explain why it does better across so many tools, both compiled and interpreted.

  10. Re:Control over employees on Why Do Employers Require College Degrees That Aren't Necessary? (thestreet.com) · · Score: 3, Interesting

    There's no question that the employer-employee relationship is unbalanced, with power mostly in the hands of the employer. But the counter-argument is that, degree or not, people jump from one job to another in order to advance their career. And that has become much easier to do in the past couple of decades, with job websites like monster and careerbuilder, and networking services like linkedin.

    Changing from one employer to another is an onerous decision, one that you want to initiate on your own terms, not your employer's. But people can do it even if they have debts. Start by building up an emergency fund, with enough to cover about 3 to 6 months of your living expenses, in case you get laid off. Then -- start to save up for a down-payment on a house, if buying one makes sense. (It may not if your career requires you to be mobile.)

    TL/DR: From an employer's perspective, I don't think that a candidate with a 4-year degree is necessarily "stickier" than one without. It comes down to the liquidity of the market for the skills the candidate has.

    And the only reason you had any need for IQ edge was because their online platform ran Silverlight for who knows what reason. Silverlight?!?! There's no getting THAT to work on Linux!

    Lately I have had no problems in linux with either IQ Edge or their website (aside from some network access problems due to my ISP that took awhile to straighten out.) I'm not sure what your Silverlight issue is.

    Luckily the online platform now works on real computers and I haven't used IQ edge since.

    Please define what a "real computer" is?

    I also wouldn't call IQ edge a full "success". About every 3rd time you open the app it will fail to run because you need to update it first (I've never seen any app that needed so frequent updates, especially with no noticable changes ever) , and while on Windows you can basically click the update button on the popup, wait a minute, and be running the new version, on Linux under wine you have to manually go to their website, find and download the update manually, unzip it, manually copy the files in to the correct locations, and then relaunch the app.

    I have had success using wine staging which is a more cutting-edge release of wine. As for IQ Edge updates, there have been a few this year, but the number hasn't been excessive. And when the updates happen, I have found that my Wine/Linux system (Ubuntu 16.04) has accepted them gracefully with minor complaints that can be bypassed easily.

    The internet, from its beginnings, has aspired to be a communication medium. In the hands of ISPs and their allies in government, it has slowly evolved into a broadcast medium.

    For Trump's base, it's more about style than substance. In 2016 Trump won by carrying the rust belt because Clinton thought she could take it for granted. He'll still have his base in 2020, but whether he can win the same crucial states again is another matter.

    As for Trump keeping his promises, well yes and no. For example, he called for a "total and complete shutdown" of Muslim immigration, and instead he ordered travel restrictions for seven -- oh wait, no, six countries, none of which have citizens responsible for acts of terror on American soil.
