  1. Re:so much for the price of batteries dropping on Searching For Lithium Deposits With Satellites (economist.com) · · Score: 1

    Molten salt storage, stors heat. Not electricity.
    Converting heat into electricity is at an efficiency range of 42%. So if you pump 100Watt into a molten salt storage, you get out 42Watt later, assuming you have no other losses.
    A Li-ion battery is over 99% efficient ... so storing 100Watt of electricity in a battery gives you 99Watts back.
    That is more than a factor of two.

    And I for my part rather have a battery bank in my living room than an molten salt tank ...

    Bitcoin miners avoid this charge, so it is reasonable for the legislator to make this point.
    They don't.
    They pay VAT and other taxes on electric power.
    And they pay on the full earnings on the coins income or corportate tax.

    They are in no way different than a 'true miner', fisher or farmer. None of them pays VAT on buying raw products, they simply 'get them' and 'sell them' and pay VAT on the sales.

    If you purchase a database from someone, how you can legally use that database depends entirely on the agreement you made to purchase it.
    No it does not.
    The agreement is bound to copyright laws. Any agreement restricting me from what is allowed by the law is void: in sane countries.

    Anyway. The directive is not about database schemas. It is about "databases", but unfortunately it is not clear from the text you linked, what actually a data base is.

    The debate about such "databases" started from the fact that "pure data" aka "facts" are not under copyright.

    This extends to a CD containing the yellow pages of a phone company. E.g. if the text can easy be extracted, you are allowed to reorganize the data, and resell it. The "organization" of that data is a database ... even if it is just a single big text file.

    Traditionally database schemas (and that was the discussion) are not copyright able. Otherwise it would be impossible to write your own software that accesses that data base via e.g. SQL.

    So: we can not copyright schemas and the data can not be copyrighted, too ...

    Here comes the EU directive, originally only intending to harmonize slightly different ideas about how to handle that topic in different states.

    The EU directive now proposes that "schema plus data" together can be under copyright under certain reasons: e.g. huge financial investment, high intellectual effort etc. And this they call "database".

    Nevertheless raw data as in facts and the schema alone are not under copyright. So: what would be under copyright? E.g. a street map (raw data that you can retrieve or buy somewhere), with annotations that you contribute your own. A database with images of stone masonry, because you have the copyright on the images. A database with a few hundred thousand microbes and the experimental results you made on them. However one would still be free to extract from that database the names of the microbes and other public available knowledge and redistribute those "facts".

    With database in this case we always mean "something" that you can put on your computer and "access" it. It mights get more complicated e.g. if you need a custom retrieval program. That is e.g. usually the case for a yellow pages CD, it most of the time comes with a small program to search and retrieve the data. Decrypting such data then again would fall under DMCS etc.

    Or running such a database "online" via a web interface would put ordinary visitors behind the end user license agreement what they can do with he data, e.g. no scrapping.

    In your country perhaps.
    Most likely in no european country.
    Downsizing, aka moving house, is so expensive it is hardly worth the effort in ordinary cases.
    It is often extremely complicated/expensive to find a cheaper place that is _significantly_ cheaper and still is close to the comfort you like. Or close to the region you need to live, etc.
    The whole AirBnN success only happens because changing house is so complicated that people rather rent out a room occasionally than moving. (And this situation was already the same before AirBnB, only renting out was not as simple)

    As I'm very often outside of germany, I enjoy the internet now, before I had data roaming deactivated and usually did not accept calls from home.

    No it does not. If you wanted to say that, the first comma would be ommited: "The party included the strippers Bill Clinton and Al Franken." or you would write a colon: "The party included the strippers: Bill Clinton and Al Franken."

    For native english speakers who happen to know the rule ... for a non native english speaker - I'm german, and we have no 'similar rule' AFAIK - it makes no real sense.

    I simply can not get it that Apple and Android developers create Apps that try to look like a 'Minority Report' future UI and are close to unusable ...

    E.g. on an iPad you can mot correct an incorrectly typed mail address. You have to delete it and type it again. Or copy paste it into the mail text, edit it there and copy paste it back.

    Android has no 'looking glass' to position the cursor if you want to correct some typing. But they have that "use the space bar as a scroll bar' to position the cursor. Some /. poster told me about that. Obviously on my Yoga book it only works with the on screen keyboard, and not with the watcom keyboard.

    The watcom keyboard includes a mouse pad. But multi touch to scroll and zoom does not work. Randomly however it scrolls down. Never made it to scroll up.

    Then again I read a few month ago that a certain browser (don't remember the brand) 'finally' added one screen down scrolling by pressing 'space'.

    A few weeks ago I realized my 'yoga book touch pad is scrolling down' comes from me accidentally hitting space.

    I never used in in any browser space bar to scroll a page. So when I read that a few weeks ago I tested it, as I could not believe it. For what actually do we have PgUp and PgDown?

    Anyway, so much to modern user interfaces ...
