  1. Re:Need open e-book libraries for competition on More On enTourage's Dual-screen E-Book Reader · · Score: 1

    Will those DRM enabled reader communicate with any computer transfering data on any direction without requiring administrative access for installing weard drivers? And will they work on Linux, BSD, and etc?

    There is a lot you lose by having the option of accessing DRMed media, take you head out of the sand.

    Yep, but factoration also isn't O(a^n) where a is constant. It is more like O(a^(n/b)) where b is quite bigger than 1.

  3. Re:Styrofoam planet a Jupiter brain candidate? on Kepler Finds Five More Exoplanets · · Score: 1

    Is there any candidate composition for it already? I mean, Jupter is slightly more dense than water. I don't know what to make from that description of a brain, it could have all the way from the density of a nebula to a rock. But from power generation/dissipation requirements, I guess it would be composed by rotating layers of satelites. At that format, it would tend to be rocky dense, not gas dense (and cilindrical, instead of spherical).

    I agree that a healthy market needs money in the masses (just never saw a stable market, mind you ;) ), that is why I said that it was close to the mark.

    Offshoring may just be the last straw, or may just be an anonimous straw. I don't have statistics on how big it was (in part because I couldn't think yet on a way to measure that), but I have a guess that it isn't the main factor. Anyway, watever importance it has, it definitively isn't the only factor, but certanly helped to make things worse. I'm still searching for candidate causes.

    I've made a one day free course on Microsoft licensing (from their oficial represntatives here at Brazil - free for some customers). It does clarify a lot, but I still have lots of surprizes whith it. Your experience may vary (even more because that course you are talking about is probably from Microsoft itself).

    They talk about oportunity costs. That means that (on average) every company could be (nearly) 10% more productive if IT didn't fail, or they could lose 10% of everything they make due to IT failure, or anything in between.

  14. Re:So only XP is out of luck? on HDD Manufacturers Moving To 4096-Byte Sectors · · Score: 1

    Hum... MS SQL server costs as much as a just-not-top-of-line server. Or maybe more now, since the crisis pushed hardware costs down (someday I'll look into buying both again, or just the server if I get luck).

    Anyway, at the same price you contract the useless Microsoft support you can hire some quite usefull Linux support. Unless you simply doesn't use support and can live with the tickets MS throws at you when buying (ok, nobody really uses MS support, but what is the point then?), the only difference in pricing is on the license.

  16. Re:If the core is a dynamo, why can't we pull curr on North Magnetic Pole Moving East Due To Core Flux · · Score: 1

    Ok...

    First, we can't get electric current from a constant magnetic field, only from the changes. Earth's magnetic field doesn't change fast, in fact, somebody already posted the figure of 19cm each minute, over some 64000km* radius that is quite a low frequency. Then, Earth's magnetic field is quite weak to begin with. Even if it was rotating at a hight frequency, it wouldn't carry a lot of energy.

    Now, you are right that the field comes from an electric current. It is a strong current, but it flows in a huge amount of conductor so is very weak at any reasonable volume of Earth's core you choose. Anyway, to directly gather that current (without induction), one'd need to probe the Earth's core (on at least two places), what is quite a task.

    * At that latitude, it is less than 64000km. I didn't make the calculations, but it is less than 1 turn every year. That is already too low on any practical sense.

    Thanks, nobody seems to notice that nowadays. I'll cite one of those differences, you (in the 'everybody' meaning) are oblied to know and understand every aspect of the law*. Nobody is oblied to understand an operating system.

    He (his company, anyway) is a platinun buyer of Microsoft. That gives him access to some (large volume) discounts and gives him support tickets on every aquisition, that he hardly spend at all*, so he always have some to spare.

    It is no wonder that you can't find platinun contracts on the internet, Microsoft makes sure it is nearly impossible to any buyer to discover what are the licensing options, so they can price target everybody.

    That is quite close to the mark, but you still missed it. US per capta worker earning* was alread trending down at the end of the 70's and begining of the 80's, before offshoring become usual. Offshoring surely had a contribution, but it probably smaler than you think. At the same time, there was an "invisible" structural change** that caused money to accumulate at the top earners of your country, and that seems to be the main culpit here.

    * At the same time, productivity was increasing. Only on late 90's it started decreasing.

    Ok, sorry by the delay, I still didn't get used to the new presentarion of comments...

    That energy figure is on TFA as the amount of energy an eruption would release. Anyway, I didn't meant to say that one'd need to let all out, even less that one should let all out on a short time, like an eruption. The poit is that there is way more energy than any man made equipment has ever dealed with, and it does need to be released, somehow, into something. Even if you have to vent just a "small" 1% of it, it is still more than a few thousand years of our current consuption, and you can't release it through thousands of years. If we discover that this beast is going to blow, our only hope is if we need to vend just some 0.0001% (that's 10e-6) of the energy, even then, we'll need a huge share of mankind's GNP just for that.

    About ground stability, as I said, I can say that there is a risk, but I don't know if somebody knows how big it is, or how to minimize it. I guess that if we discover that it is going to blow, that won't be relevant, but while we don't know, we must research both possibilities.
