  1. Re:Robots only use C on C Programming Language Back At Number 1 · · Score: 1

    It is used for applications you want to be small (to download mainly) and reasonably portable. It is also done for lots of applications that don't have those requisites, but where the developers think it would be more professional looking. Also, obviously, C is used on number crunching applications.

    Some people also write things on C just because they want. The only ninche where C is rare is internet applications (even then, the middleware is nearly all in C).

    Prolog has still more gramatical power than Perl, yet, it is mainly implemented on C. There is a huge difference between a generic powerfull parser and a programming language parser (the programming language being LR1), and the parser is one of the easiest parts of a compiler.

    Numbers 5 and 6 aren't true yet. But the thing is number 7... One'd expect database driven programing to be done on a language that understands databases from the back of their hearts, like earlier web programing was done on Perl (that understended strings), and current is migrating to ASP like languages, like PHP, that understand HTML. I know of no language that does that today.

    After all said, I still expect you to choose a language that knows about strings when doing web development. Well, SEGFAULT will select the developers that don't.

    Oh, great! Research hard enough and you'll discover that the EROEI if this thing is below 1. Now, take some time for looking into other bateries, and you'll see that they have something in common, all of them have EROEI below 1.

    That unit is spelled "kWh", with small case "k" and "h", and no "r". The kilo prefix is always small case, and hour symbol is just "h". Upper case "K" is the abreviation of Kelvin (temperature unit). The prefixes biger than "k" are all upper case, like "M" (mega), "G" (giga), "T" (tera), but the smaler ones are all lower case, like "m" (mili), "n" (nano), "p" (pico).

  16. Re:Energy not Power and Batter Life on Largest Sodium Sulfur Battery Powers a Texas Town · · Score: 1

    The refurbishment cost will probably not be very hight. Sodium sulfur bateries get old because sulfur leaks into the sodium container (that was on that wikipedia article some time ago, maybe they removed because it is wrong), so all you'd need to do is to repurify the sodium.

    Now, of course, since the calculations yeld a 90 years life time, something will surely happen earlier, and the battery will need some unforseen maintence.

    Well, if oil runs out, the worst option for eletricity generation will be a diesel generator.

    "You think you can build a wind turbine with wind power?"

    Why not? Really, give a reason for one not being able to do that. EROEI is ok, minerals are ok once you adopt a (more expensive) process of refining that uses eletricity instead of oil, mining is ok, transportation is ok. You'll need some bio oils for lubrification, plastics and rubber, but everything quite on the realm of the possible.

  25. Re:Warming is not bad on House of Commons Finds No Evidence of Tampering In Climate E-mails · · Score: 1

    Sorry to put some facts on the table, but water is necessary for some very central functions of plants, and they need not only some water sorage, but also water flow (in special, water flow is necessary for growth). So when you take any amount of water away from them, productivity goes down. That happens when different species are compared, but also the same plant will grow faster with more water than with less (except on extreme situations). Reducing the average raining on farmland will reduce yelds.

    Now, about that extra land, well, plants also need insolation. It doesn't matter the temperature, with a small insolation you won't get too much productivity. And guess what, permafrost land isn't on the tropics or temperate zones. All that land will make a surprizing small contribution to total yelds.

    Of course, global heating could cause the rain on arable land to increase, what may cause yeld to increase, or may not. Most comercial crops can't survive at hight temperatures, but it may be possible to change them, or replace crops, or it may not. Also, global warming will more probably cause more disarsters like huricanes and floods, but there is a small possiblity it will cause less. Who knows?
