  1. Re:Angular Momentum on Internet's Energy Needs Growing Faster Than Efficiency Gains · · Score: 1

    Per the Daily Mail, that great bastion of scientific rigor, we find that the internet has a mass of about 50 grams, "the same as a strawberry":

    http://www.dailymail.co.uk/sciencetech/article-2057018/Internet-weighs-strawberry.html

    Then the angular momentum of the internet about the center of the Earth is (50 grams) / (24 hours) * R, where R is the mean radius of the internet from the axis of rotation of the Earth. Computing R is hard, since the parts of the internet in Europe (far northern latitudes) will contribute less than those near the equator. If we take R_earth cos 45 as an estimate for the radius (which is probably sensible, roughly splitting the difference between Europe and the US/Japan/Korea), we get that the angular momentum of the Earth is

    2.6 kilogram-meters per second.

    still be cost-effective compared to business as usual.

    If it were cost-effective, wouldn't businesses have already done it?

    The problem is that power is artificially cheap; the price of the damage done by carbon emissions is not included in the price of burning coal. Seen this way, a carbon tax isn't an artificial meddling in the market; it's the removal of the subsidy that people burning carbon enjoy right now, in that they can cause environmental damage without bearing the cost (or, if you like, consume part of a limited resource without having to pay fair market value for it, where that limit is the sustainable level of emissions).

    Remove that, and you won't have to impose efficiency from above; people will do it naturally, as a way of saving money.

    Neutrinos have mass too; this was discovered by the fact that they oscillate from one flavor eigenstate to another.

    This is sort of like the way Catholics have mass; they have a cracker that oscillates from bread to jesus, showing that the eigenstates of flavor aren't stationary states of the Hamiltonian...

    Resources aren't all that finite. Right now, what's the problem with using power? Carbon emissions. But there are lots of ways to make power that don't involve carbon-based fuels; we just need to do them.

  7. Re:What about the Energy offset? on Internet's Energy Needs Growing Faster Than Efficiency Gains · · Score: 2

    Is it CPU cycles that take the power?

    Suppose I stream a DRM'd movie from Netflix that's 4GB. I don't know how to measure it explicitly on my computer, but I know I can do the decode entirely in software, and that the TDP of my CPU is 35 watts. I doubt that the difference between playing the movie with and without encryption is that big of a fraction of that -- perhaps 5W?

    How does that compare to the power used by the routers etc. that carried that data to me?

    As someone who works in scientific high-performance computing:

    1) N -- the most interesting thing from an engineering perspective is the number of MPI threads or whatever ("How many ways am I going to parallelize this thing"), and while you can sometimes get benefits from understanding that two threads running on different cores of the same CPU can communicate faster than two threads on different machines, it (at least in lattice gauge theory, what I do) is not that big of a deal.
    2) Not usually, although there are some allocation-granting groups that have conversion factors ("We give you X million core-hours on this machine, here's a conversion table for our other machines.")

  11. Re:Natural result of government power over somethi on No "Ungoogleable" In Swedish Lexicon, Thanks to Google · · Score: 1

    But even if many languages do have such official bureaus, it is not right to think that these bureaus would have actual power to dictate what language people use in everyday communication (how silly would that be?). To the contrary, they are reactive rather than proactive: if a new word is documented (in press, literature, etc.), they investigate it and possibly add it to the lexicon.

    This is a totally different thing (and IMO a natural and good thing) -- someone who just keeps tabs on the evolution of a language. English has no official body that does this, because nobody owns the English language, but there's the Oxford English Dictionary, etc...

    I use it as an everyday desktop OS. So did most of the people at the institution I used to work for. Granted, this is a university physics department, but all of the machines on professors' desks ran Linux (except for the die-hard Mac types), and they often used them not to do anything especially sciencey but just to do the ordinary things: read mail, watch cat videos, write mail, write documents, run spreadsheets...

    I don't understand the technological issues with Linux as an "everyday desktop OS". It works just fine in that regard -- you have a file browser, a web browser, an office suite, a mail client, and so on. You have window-management features that are as advanced as you are willing to put up with (in KDE, at least), a search thingie, and so on. You can use Kubuntu/Mint/Unity/whatever without ever opening a terminal. But, if you *do* speak bash, you have the freedom to make use of it as another tool in your toolbox to get stuff done.

    He didn't know. A bloody *cop* didn't know which way north was in his own city. I then asked him "In which direction am I more likely to get shot, this way *points*, or that way *points*. He tells me, and then I know which way I'm going."
