  1. Re:Comment from a Chemist on Has the Ethanol Threat Manifested In the US? · · Score: 1

    Ethanol, as produced in Brazil, doesn't need to (but most probably uses, since biodiesel here is more expensive than regular diesel).
    Even using diesel, amounts are small compared to energy production, crops are near the distillery.
    The distillery itself has a positive energy balance, not including the ethanol it delivers (co-generation, using heat to produce power). Heat comes from burning the biomass byproducts.
    For example, one ethanol producer in Brazil states in it's page an capacity of 940MW to be sold. http://www.raizen.com/pt-br/se...

    I wouldn't count on it taking any job from a CNC machine. it's a MIG welding machine and it's resolution/accuracy should be well over 1mm. It won't deal with a lot of metal also.
    No, it's not the one size fits all.
    It's very useful and interesting, allowing complex geometries more easily and I think local shops will have one once the techs (his and other techs for metal 3D printing) are mature.

  5. Re:Dying gasps on C Beats Java As Number One Language According To TIOBE Index · · Score: 1

    I've made embedded programming in C++, in a rather efficient way. It makes a lot of things easier, but it's much harder to find someone that knows what that thing is doing. If you handle a task to an experienced C++ programmer and say no use of new, delete and exception handling are allowed, probably the task won't get accomplished unless it's very simple.
    I used to advocate the use o C++ on embedded, but gave up. In a larger environment with programmers of different experience levels, C is much easier to get running.

    Hit the nail.
    If you have at least a little experience, you've already at least once gone through the codebase and asked who's the idiot that wrote that, checked the answer on the version control system to find that the idiot is yourself.
    On the other hand, sometimes the legacy code is so much patched that it's easier and faster to rewrite it. If this code is that much patched that you can't even follow the code flow anymore, bugs left are only the scary ones anyway. Rewriting that code is a high risk task, since many errors already solved will be done again, but may still be worth it.

    No, redundancy means excess capacity.
    Diversity means spreading the capacity through various locations/processes/etc. In this case we're talking about geographical diversity and the difference is simply distribution of the fabs around the world. If TSMC had its 15 factories spread over various locations, a single event couldn't shut down 100% of it's capacity.
    The last year's earthquake in Japan shot down 1/3 of the Renesas fabs. It was enough to make a huge problem, stop some auto manufacturers, but it kept running. Had Renesas all it's fabs on North Japan, it would be 100% down. The fabs were not redundant, as one could not cover for the lack of other.

    It's about diversity, no redundancy.
    For semiconductor manufacturing, for example. There's quite a few plants around the world, not that much of small process nodes. If a major earthquake hits Taiwan, shutting down TSMC and UMC factories, you'll notice the effect all around the world pretty fast.

    You're always limiting the rights of other people, including their right to live, by asserting your rights. The problem is where to draw the line.

    I disagree with that thesis entirely.

    Their right to live does not mean in any way that I'm required to surrender mine. Just because you might need an organ donation, doesn't confer an obligation upon me to give it to you. The same as the "right to life, liberty, and the pursuit of happiness" doesn't actually guarantee you a job or to be happy ... merely the right to look for it.

    I'd say you just confirmed my point. You don't have to surrender your right simply because the papers would be reversed then. Someone shouting that this or that genre of art is disgusting and should be forbidden is attacking a basic right (free speech) of someone else is just like someone shouting that organ donation should be compulsory is attacking a basic right (physical integrity or even your right to live).
    Also, you can give someone the right to look for a job or happiness with no feasible way to achieve the goal.

    Because, as soon as you start doing the calculus of whose life is more valuable ... you start using the poor as spare parts for the rich.

    Sure. Don't we kinda do that already, in economic terms? (poor people's work pays rich people's health care while having (almost) none themselves)

    In my opinion, both of your examples are nonsensical and contrived. That isn't about 'offending someone else's sensibilities' .... it's about making your own rights inferior to that of someone else. I don't see any ambiguity in where to draw the line you seem to think is a broad and fuzzy expanse ... your rights can't extend past the security of my own person.

    You may redefine the security of your own person to include quite a lot.

    It's amazing how vocal people can be about making sure that the rights of other people are limited so as not to offend their own sensibilities.

    Very true... Suppose there's a hungry vampire just in front of you, about to die if not by your blood. Which right to live is bigger? (from a book I read a long time ago). Let's get a not so hypothetical and fantastic case, let's say you're in front of a severe renal patient and known to be a compatible donor. You don't want to live with a single kidney, which right is more important, his right to live or your right not to have your organs harvested?

    I mean, the pure text interface is much less inviting to mess with than a graphic and iconic interface.

I consider that to be true also with OS configuration or any software.
