  1. Old news. on Java IO Faster Than NIO · · Score: 4, Informative

    Look at the timestamp of this presentation :) It's a bit of old news.

    It was discussed here: http://www.theserverside.com/news/thread.tss?thread_id=48449

    And it mostly shows that NIO is deficient. I encountered similar problems in my tests. Solved them by using http://mina.apache.org/ .

    "I fail to see the problem. This is a very likely possibility. We deal quite regularly with infinite series in mathematics, where the correct outcome relies on the infinite nature of the series."

    It's more like infinite number of cardinals. Which poses a problem, because there's going to be the strict hierarchy of gods.

    "Will there ever be an "end of time" or "end of existence"? What comes after that? Nothing? Anything? Was there ever a "beginning of time" or "beginning of existence"? What came before that? Nothing? Anything?"

    Now think about it some more. How do you define the word "before"? Does it make sense to say "before the beginning of time"?

    To actually define this you need to embed our Universe inside of a larger Universe which should still provide an arrow of time for your question to be valid.

    "What with the law of conservation of energy and all, it certainly seems that everything we can observe is infinite. Not infinitely stuck in the present state, but infinite nonetheless."

    So far, our Universe seems to be finite (albeit very big).

    "You can't create or destroy matter or energy; you can only change its state. They are infinite."

    Sorry, this statement has no sense.

    "So why not an infinite chain of gods? An infinite chain of creators. We create things all the time. We're figuring out how to create more and more things as time goes on, in fact."

    Occam's razor. Why do we need gods if we simply can have infinite Universe? Also, that obviates the problems with low-probability events - in an infinite Universe any event is bound to happen.

    "You yourself argued that Kalam's argument requires an infinite chain "ad infinitum". This would mean that our creator could potentially be involved in creating other creators, since the chain before our creator is infinite, so why stop with ours."

    Wrong. That means that our creator must be created by some other creator which is created by some other creator, etc. It's not logically inconsistent, but fails Occam's razor.

    On the next level, why not think about possibility of continuum (aleph-1 set!) of Universes/creators? :)

    "Islamic thinkers used pure reason to derive the fact that our universe had to have an origin, and thus that the universe tended to show evidence of God, rather than the opposite... back in the middle ages. (http://en.wikipedia.org/wiki/Kalam_cosmological_argument)"

    Kalam's argument is stupid on many levels.

    First, it's applicable to God - it also has to be created by something (a meta-God?). Which in turn must be created by something else, ad infinitum.

    If you try to apply an argument that God is infinite and thus has no beginning, then this argument can very well be applied to the Universe itself.

    And this is only on a level of philosophical arguments (i.e. within the model postulated by the author).

    If we look at the real world, we'll see events happening without cause everywhere (virtual particles, radioactive decay, etc.).

    And General Relativity also posits that it's possible to have the 'beginning of time'.

    "How do you measure qualification in any field of literature analysis"

    Answer: we don't.

    There are no objective criteria to judge the quality of literary analysis, philosophy and theology, they are entirely subjective. Once a text in philosophy/theology passes the basic test of self-consistency and coherency, one can't really judge if it's 'bad' or 'good'.

    So PZ Myers text of "The Courtier's Reply" ( http://scienceblogs.com/pharyngula/2006/12/the_courtiers_reply.php ) isn't really better or worse than "Summa Theologica" (yes, I read it - still can't scrub my mind clean).

    PS: I've studied hermeneutics as a part of the course on mathematical logic. I suspect, mostly to show that hermeneutics isn't really related to any form of formal logic.

    I like English spelling for example. It's so easy! One just needs to remember how words are spelled. The same for pronunciation, there are no general rules. Just remember how words are pronounced!

    I'm not a native English speaker, but English for me was harder to learn than German (which has word genders and complex morphology).

    Ukrainian was by far the easiest, its writing system is completely phonetic and rules are rather straightforward. Though it's a bit skewed, since Russian is my native language.

    To be fair, it's possible to do garbage collection without stopping _any_ mutator thread (i.e. threads doing useful work). Though it's really really hard.

    It's so hard that Azul systems had to design their own CPUs to do this - they have a hardware assist for read barriers. They do scale to thousands of CPUs and terabytes of RAM though.

    Go has the same problems. They try to make it 'simpler' but along the way they actually make it more complex.

    For example, try-catch-finally idiom is an easy and standard way to deal with exceptions. But no, they had to invent their own half-assed implementation just to be 'minimal'.

    Also, they insist on using fucking _return_ _codes_ to indicate errors. WTF? It only makes code more complex because of tons of stupid 'if error' statements.

As for chemical toxicity, the amount of waste is so small (even with our current reactors) that it doesn't matter.
