By the time I thought, this story might be interesting. Well, I had problems getting it to download. So, I thank you for your patience. Really, I normally do read articles.
I agree with this to a point, yet, there are considerations that a human will take into account. For instance bad grammar produced by quoting or paraphrasing a source.
For instance, an essay on Tom Sawyer would naturally be full of intentionally bad grammar, and words that don't exist (archaic slang). This would be easily recognized by a human, but would be difficult for a computer to grade fairly.
I disagree. The computer spits out a number, and you get to live with the results. I imagine a paper that's both on topic, and well organized... but uses different verbage in the initial description and the conclusion. Perhaps using words that were introduced throughout the body.
A computer will probably not be able to recognize this. A Human would.
... and produced results virtually
identical to those of trained readers.
Funny, because the way I read that is,
"Produced lawsuits where the cost is
virtually identical to about 20 times
the short-term savings."
I see this coming from both sides. The
obvious, the grading was wrong, and I
lost a scholarship. To other people
suing after dropping out of collage level
english classes (the test said I was
better than I was).
How does a viral reproduction and spreading differ from what any animal does then? When a lion kills it's prey, the lion can then flourish and provide for it's young. The lion lives off of resources that are not it's own (at least from the gazelle's point of view).
A virus uses the cells of a living organism to reproduce, destroying that cell in the process. A population of virii can destroy an entire organism, and subsequently spread to other organisms. However, usually, it doesn't kill an entire organism, instead it reproduces enough to move onto another host before that host can eradicate the viral infection.
Humans do much the same as both the lion and the virus. It is human creativity and intelligence that make us "more dangerous" to the environment. However, with the possible exception of a fossil fuel shortage or a global nuclear war, humans are not in danger of 'using up' all of the resources on the planet, just as lions are not in danger of eating all of the gazelles in Africa.
On the other hand, just like a pride of lions in an area where there are few gazelles, the environment may, some day, push back and cut out population that consumes too many temporary resources. This, invariably, would be considered a failure of science, or some such -- but really, it's more like the song, "Godzilla". "History shows, again and again, how nature points out the folly of man"
What I'm saying is, as far as I'm concerned, the virus line in the Matrix was designed to introduce FUD. That is why I said it's hip and Matrix-y. Because, as far as I can tell, the comparison has no basis in fact. But it sounded so cool when Hugo Weaving said it so smugly...
I imagine Darl McBride, with Hugo's voice saying, "Linux is not like any other x86 operating system. But there is one operating system Linux compares to...UNIX. Like UNIX, Linux multi-tasks cleanly, and runs 'top', 'bind' and 'X11R6', so it must actually be UNIX... You know what I hate about this State... it's the smell... Mormon incense permeates everything."
Back to reality, I'm happy that you are agreeing with me, but I resemble^H^H^H^Hnt being compared to a virus!
I, for one, have learned a lot from this article and many, many informative posts within it.
So does anybody have a good,cheap,quick (pick two) primer on Quantum Physics? Something that can explain what we do know, along with the outstanding issues that we don't know?
You are correct that I am coupling common sense with some thoughts, in an attempt to casually learn something. I thank you (and many others) whom are taking the time to teach.
To clarify what I was saying with negative (again understanding that I have a huge hole in my head where this knowledge should be)...
My limited understanding of negative energy is that there is a pushing away (not gravity) that is basically making the innards of the universe catch up to the faster speeds of the outer reaches of the universe. This pushing, to me, seems similar to the generally outer movement of photons from any light source.
Obviously, if a photon itself has no mass, then it could not have this outward pushing effect, but it also seems that the search is for something that has the same outward push.
I guess it's time to teach myself Quantum Physics. .. At any rate, I'll need to know it for common IT work soon enough.:)
I hate when I start slightly funny and end up learning something.
Two questions, since you seem to actually know a thing or two on this subject...
1) Why could there not be an Exponential effect of gravity? That is to say, what if two massive objects that are near enough to transfer gravitational energy then exponentially magnify their gravitational pull to form a 'super gravity'?
2) Could the non-mass of individual photons actually have mass, but mass that is so omni-present that is is impossible to detect under usual circumstances, but when dealing in the scale of galaxies the effects are observable?
I ask these with confidence because I'm sure I'm not the first to ask these questions, and I'm sure someone has already figured out why neither of these scenarios would work.
I'm really thinking out loud here, but I have some serious questions.
Photons are normally considered to have zero mass, and to be the smallest possible unit of energy.
Yet, they are also "negative", are they not? That is, they move away from their source.
Yet, if a photon will be absorbed by some types of objects, bounce off of others, and simply pass through others - it must have some sort of mass. Where does a photon go when it's energy is spent?
There must be a near infinate supply of photons that have no energy or are waiting to aquire it. It would seem that these photons - assuming they do have mass, in the same sense that electrons have a larger mass, could explain both, no?
Again, let me clarify - I do not claim to know something, I am requesting feedback and education.
While, at first, I will admit that I was embarrassed by my own oversight, after reading your links, I'm not sure that they are different.
While they are defined differently, I would point out that "dark energy" is often attributed to a great deal of the mass of the universe (second sentance from your link).
And dark matter is defined as this type of mass, but without explicitly mentioning the energy -- Einstein has some theories on that as well -- inherant with any amount of mass.
I'm not saying that these are the same thing, but I would merely say that this distinction isn't made clear by the Wikipedia.
I would be highly interested in hearing a better explanation of why these two concepts are distinct.
Supposedly, the "edges" of the universe are expanding outward at the speed of light. The rest of the universe is slower, until you meet the - so-called - center which is a virtual stand-still.
I should point out here that it's also been theorized that the center is in fact pulling things back in - but this is an old theory, that hasn't gotten much press lately.
The accelleration of the expansion is about the inner layers of the universe accelerating to match (more closely) the speed of the outer edge.
So, it's not really acceleration beyond the speed of light, but an accelleration of the slower contents within the universe.
Think of an empty baloon in a centrafuge. The heat will make the baloon expand, and as the spinning keeps moving, the inside air will press harder against the sides - causing more heat and more expansion. The air that's not at the outside is going to "catch up" to the air at the edges.
Of course, this needs to be adjusted to understand that the "balloon" has no outer bounds, isn't going to pop, and has a near infinate amount of matter inside..
Don't you get your science from Monty Python movies. It was explained quite succinctly, in the Meaning of Life.
Whenever life get's you down, Mrs. Brown
and things seem hard and tough,
and people are stupid, obnoxious or daft,
and it feels that you've had quite enough---
Just remember that your standing on a planet that's evolving,
revolving at 900 miles per hour.
It's orbiting at 19 miles per second, so it's reckoned,
a sun that is the source of all our power.
The sun, and you and me and all the stars that we can see
are moving at a million miles a day,
in an outer spiral arm at 40,000 miles an hour,
in this galaxy we call the milky way.
The galaxy itself contains 100 million stars,
it's 40 thousand light years side-to-side.
It bulges in the middle 30 thousand light years thick,
but out by us it's just 3000 light years wide.
We're 30 thousand light years from galactic central point,
we go round every two hundred million years
And our galaxy is only one of millions and billions in this amazing and expanding universe.
Musical interlude
The Universe itself keeps on expanding and expanding
in all of the directions it can whizz.
As fast as it can go, the speed of light, you know
A million miles a minute and that's the fastest speed there is.
So remember when your feeling very small and in-secure,
how amazingly unlikely is your birth.
And prey that there's intelligent life, somewhere out in space,
'cause there's bugger-all down here on Earth.
I am eagerly awaiting the next annoncement where
someone again finds evidence to refute the dark matter
claims. It seems like the science; "Dark Matter
is like this" - "No, it can't be, actually it's
like that". Is not going to end soon.
Join me. Come to the dark side, and together, we
will expand the universe.
I'm really not sure what one has to do with the other.
By the basic logic, then I should not sit and read SlashDot until my house is paid off. But my house will not be paid off for 30 years. Perhaps I should not purchase internet access, as the $50 per month that I spend would do better paying off my house, regardless of what other benefits internet access might give me.
Seriously, if you want universal healthcare... tell your congressman and representative that you will vote for whomever is willing to support it. Tell your friends that this is what you are doing. Then, actually vote that way. Same idea for big oil... Vote green, ride a bicycle.
In the mean time, some people (at least me) think research is usefull and worth some tax dollars.
From my perspective manned space exploration does make sense. Surely, a rover on Mars is a very cool thing, and can accomplish a lot on it's own. Yet, a human can accomplish so much more on a much shorter time.
Further, isn't it just human nature to want to go?
What gets to me about spammers... They obviously feel they are doing the world a favor by offering sexual deficiency drugs, pain-killers of questionable legality and mortgages for those with bad credit.
I always picture spammers as bereft of libedo and credit, with drug abuse problems. Really, wouldn't that explain a lot?
US$15,000 for a single CPU instance of Oracle.
But, they won't sell it to you without software updates support for the first year.
That's some serious dough... but the good news is that if you don't run Oracle in a commercial/production environment, you can download and develop against it for free. So, really, Oracle also tries to benefit from the OpenSource mentality. If no OpenSource project supported Oracle directly, then Oracle wouldn't be nearly as popular. So, they let you download and run it (and have allowed this for over 6 years).
Yeah, there was a Barnes and Noble link directly in the Article - at the same price as Amazon. I thought I'd point that out lest anyone think that your Amazon link is somehow superior to the BN link that's already in the article.
Yes, it's at the bottom, and nobody reads the entire book review.
I find your example of Oracle/Apache quite funny, being Oracle comes with two Apache products, httpd and tomcat.
I, also, use Oracle, but that's because of an interoperability requirement that was pre-existing to my ability to put Linux across my server base. Otherwise I'd have used PostgreSQL.
Slashdot Mirror
So, are you the victim of torture, now under the delusion that the PRC and the RoC are actually the same?
Yet, after all this, are you sure there are not five? Try again, how many lights do you see?
By the time I thought, this story might be interesting. Well, I had problems getting it to download. So, I thank you for your patience. Really, I normally do read articles.
Does the story differentiate between the two?

Comparing humans to virii, while hip and Matrix-y, perhaps goes a little too far. I have no intention of moving to another planet.
