  1. Re:Quothe the raven, "Forevermore". on There Is a Finite Limit On How Long Intelligence Can Exist In Our Universe · · Score: 1

    It's a consequence of the laws of statistical thermodynamics: That entropy always increases. There is a practically zero chance of entropy decreasing, and intelligence would need to exist in an area of decreasing entropy all the time. The chance of this is zero. Boltzmann brains are consequence of entropy decreasing, but these would survive for even shorter periods on average, as the universe they exist in will be closer to maximum entropy (on average).

    One exception I can see to this, is if the state space of the universe increases. If it does then a maximum entropy state might never be reached. Anyone know enough about inflation and gravity to say if this is true for a universe that increases in size?

  3. Re:There I fixed it for you... on How Responsible Are App Developers For Decisions Their Users Make? · · Score: 4, Insightful

    Users are responsible for their own decisions. If developers have an ethical obligation, then it's to inform and train users, so that they can make better decisions.

    I wonder if ultra-violet light would work. This should then provide even more bandwidth than visible.

    I don't think being a better fighter has anything to do with it. It's not like they'll be facing off before starting a fair fight. One will attack while the other isn't expecting it.

  8. Re:Microsoft Sculpt Ergonomic on Ask Slashdot: Good Keyboard? · · Score: 1

    I really dislike the placement of the Insert key below the double-height Delete on the UK version (apparently it's the same on the US one too). But the keyboard looks so damn sexy I've forced my muscle memory to adapt.

  9. Re:Circumcised at age 18? on World's 1st Penis Transplant Done In South Africa · · Score: 1

    Doctors say South Africa has some of the greatest need for penis transplants anywhere in the world.

    Made me laugh, but it's obviously a serious problem.

    I completely agree.

    That seems fair. Screwing companies out of money should be the customers default position. After all, the companies' default position is screwing money out of its customers. That said, if a company has my good will, I'm not nearly so niggardly.

  16. Re:What a piece of shit on Building the Developer's Dream Keyboard · · Score: 1

    With another "mode" key (Num-Lock?), he could turn the right-half into a numeric keypad, so that JKL becomes 456. Maybe another one (errr... Edit-Lock?), so they become Delete-End-PgDn, or Left-Down-Right? Fuck it, I'll just design my own. And write an article about it.

  19. Re:Problems in C++ on Is D an Underrated Programming Language? · · Score: 1

    Dude, don't use square brackets with STL arrays and vectors, just to make your code more readable. The [] operator skips bounds checking, which is the main reason for using these classes in the first place. At() is the proper methodology to use in pretty much every case, unless you are so confident in your bounds that its worth the trivial speed increase in access time.

    Bjarne Stroustrup's solution:

    template<typename>
    class Vec : public std::vector<T>; {
    public:
    using vector<T>::vector

    T& operator[](int i)
    { return vector<T>::at(i); }

    const T& operator[](int i) const
    { return vector<T>::at(i); }
    };

  21. Re:How about someone who groks the math, comment? on Quantum Physics Just Got Less Complicated · · Score: 4, Informative

    A quantum state of position can be written as a superposition of a momentum states; the position is certain and the momentum is uncertain.

    A quantum state of momentum can be written as a superposition of position states; the momentum is certain and the position is uncertain.

    That's the duality and the extremes of the uncertainty principle. The mathematics can also show more generally, that the uncertainty in position and momentum is always more that a certain value (Planck's constant).

    These things follow directly from the axioms of Quantum theory, Hilbert spaces and any two non-commutative operators. So I really don't see how Quantum Physics "just got less complicated". It's the same as it's always been. Although I've not read the paper yet, maybe that makes more sense.

  23. Re: Advertisement? on FreeNAS 9.3 Released · · Score: 1

    I tried both FreeNAS and NAS4Free for a home server, and they were both good for what they aim to do. The problem I had was when I wanted to run something other than a NAS on the same box, such as tvheadend. I consequently tried OpenMediaVault as this is based on linux. In the end, I concluded that these only work if you're running your box purely as NAS. After a look at virtualisation using docker, and concluding that this was overkill, if not a bad idea, I went with Ubuntu Server and webmin. The storage is using BTRFS. I could have used ZFS, but BTRFS seemed a better choice, for what I wanted, at the time.

    Note that if you want proper NAS, you'll probably want to avoid everything I've done at home. :)

  25. Re:All the Kindles are on sale... on Apple and Amazon Launch Black Friday Price War · · Score: 1

    I have a Nook. This has a passive screen. Great for reading in bed before going to sleep or in direct sunlight. It doesn't shine a light into your eyes keeping you awake. I believe the Kindle Paperwhite does have a light, but I guess you could switch that off. I'd probably just get the Kindle if I didn't already have the Nook. I can't see any advantage with the Kindle Fire over my Nexus 7 though.
