According to "traditional" theory, the person going INTO the black hole would appear to never get there. Not so from a person who is a safe distance away watching with a telescope.
What is new is that this new theory predicts that the person WATCHING would also never see the event horizon. How this works is completely unclear from the article. They seem to be saying that new black holes cannot form.
However, simple physics predicts that if you get enough mass in a small-enough area, the escape velocity exceeds C, so black holes CAN exist.
Somewhere there is a contradiction. Can somebody explain?
If you read it to check if its still there, then you have refreshed it.
According to Heisenberg, the only way NOT to alter the DRAM is to NOT look at it. Reading the RAM will alter its contents. Isn't that the way it works;)
but I think there is an interpretation of the Many Worlds/Parallel Universe view of quantum mechanics that a new instance of reality would be created (a new universe) that would effectively provide a level of separation.
What you are citing is, IIRC, the "many worlds" interpretation of quantum theory.
The math of quantum theory only predicts the results of an experiment, however there is no proof for the "multiple universes" theory, nor is there an experiment that can prove it. Multiple diverging universes is more of a philosophy, and one that I find to be rather absurd on the face of it. Another option is the "copenhagen" interpretation, and there are others. Some wikipedia reading for you:
I remember reading about one that made a lot of sense to me (bit I can't recall the name) that relied on photons traveling backwards in time to resolve the "spooky action at a distance" problem. The rules were structured such that time travel was impossible, as you could not send "information" backwards. If you accept that it is possible for photons to go backwards in time, it solves a lot of the other messiness that quantum theory generates. Anybody have any links on this?
Agreed! I haven't personally owned a computer for about three years, but with Starcraft 2 coming and now Fallout 3... I think I'll cave in and get one.
Must be hard typing messages that long on your cell phone keypad. Moleskin is supposed to work quite well for thumb blisters.
If you or your business really needs to have spot-on accuracy when it comes to color, the $2500 for the Adobe suite will be a drop in the bucket compared to the %50,000 print run on a conventional press.
It seems to me, who is NOT a professional in the field, that this is not that big of a deal. The original post brought up CMYK, as well as needing to teach these skills to several people in his company. Well, if Gimp/(other graphics program) can't do CMYK, he could still teach it to them, and then the company could have one Photoshop computer that could be used for the final RGB to CMYK conversion. That way you could have only one copy of the expensive software instead of a dozen.
Of course, I am talking out of my posterior. I am certain that others with more experience will point out how this won't work.
Once I was in a Radio Shack, and I saw a USB cable for about $20 dollars. Next to it was a USB hub with a cable (same length) for about the same price. How do the people who run those companies sleep at night?
Hurricanes were what convinced me to stick with a land-line. The key word in communications is redundancy. If you want to maximize your chances of being able to communicate, you have to maximize the methods -- cell phone, wired phone, and internet.
Another advantage of land lines is that they are easy to use and are fixed to our address. I have two small children (4 and 6), and if something happens to my wife while I am at work, my children can call 911. A land-line is just soooo much easier for that reason: Pick up the phone and press 9-1-1. With a cell phone, you first have to find it (can be very difficult). Then, you dial 9-1-1 and press "send". You had also better hope that the GPS in the phone works OK inside, otherwise the ambulance might not know where to go. No problem in this regard with a land-line.
Oh, and when you are talking on a corded phone, you are not giving yourself brain cancer. I know that has not been conclusively determined, but it is at least a posibility.
Oh, one more thing... If you don't have a land-line, how do you call your cell phone to find it when you loose it?;)
First, figure out what your slowest player is. Then, delay the others to match. Note that a lot of cat-5 cable might be useful -- about a mile or two should do it.
Use an osiclloscope to compare two different devices, and figure out how much delay you need. Figure that eight inches of wire is about a nanosecond delay. Note that you might have trouble driving a mile or two of cat-5, so you might have to throw in a switch or hub along the way -- which will introduce additional delay. Simply measure the delay and use less cable.
I could be wrong, but don't organizations like the BSA go after the companies and not the individuals?
It seems to me that the best thing to do would be to write e-mail to the company bosses and tell them your concerns and your recomendations, and BCC it to a separate e-mail that you control. Then forward the responses. Do what your bosses ask, and if the BSA comes knocking, show them the e-mails.
Where everyone dropped the ball wasn't on the gun purchase, it was not seeing that this guy was borderline psychotic and belonged in a secure facility, not out in the world with the rest of us. Unfortunately, the mental healthcare system in the U.S. has been almost totally disassembled over the last 40 years, to the point where it's now nearly impossible to keep anyone in an inpatient facility for more than a few hours, without a court order, and the courts are very reluctant to do that.
Well, I can see reasons for that.
"Gee. Let's get aunt Bertha committed. We will then get the courts to appoint power of attorney to us, and we will re-write her will."
With that being said, this is a very difficult line to cross. On one hand, if it is difficult to get people into a mental institution, you can have cases like the one in Virginia. On the other hand, if it is too easy to get put in one, it is kind of like being thrown in prison without a trial.
I do know how frustrating it is. Towards the end of her life, my mother began havine bevaioral problems (dementia). Unless you are suicidal or have a judge rule on the matter (very expensive, believe me), you have to persuede them to go voluntarily.
With that being said, I cannot believe that/. allowes such a piece of crap pile of propoganda to be submitted as an article. Great idea! Let's ban extra magazines (Glocks and other semi-auto pistols take "magazines" and not "clips"). Never mind the fact that the guy already has two when he purchased the Glock.
If we go for desktop machines, there are two approaches:
** Custom-built ** All machines would be the same. Yes, you can swap parts, but the system as a whole will be more expensive. Pluggable cards means a bigger case (more money), more connectors (more money), more board space (more money), more mounting hardware (more money), and more complex assembly (more money).
** Ad-hoc systems ** This uses hardware "cast-offs," such as outdated technology (would be great for the environment, since you could recycle old computer systems). This also presents problems, since each system would be, in effect, unique. Some would have sound card A, some would have sound card B. Others would have graphics card X and even more would have graphics card Y. Same goes for mobo chipsets.
Just ask a big business how well this works. This greatly complicates administration when you have to include different drivers. Businesses tend to buy a lot of computers that look alike just to make the job of maintaining them easier.
Another thing to keep in mind is that outdated technology was once top-of-the-line bleed-edge power-hungry technology. Even a Pentium 133MHz system still probably required a 150 Watt power supply. That is a LOT of hand-cranking on a generator if the village does not have electricity.
*** OLPC approach *** Also, keep in mind that the OLPC has no moving parts. The hard drive has been replaced with flash memory. Everything runs cool so there are no fans and no posibility of overheating. These things should be VERY reliable, assuming the kids don't use them for footballs. Hardware is uniform. If the software works on one system, it will work on them all (the only thing that won't be uniform is the local language).
True enough. However, the speed is a by-product of the design. The important factors in silicon production is: * Raw silicon area (die size) * Geometry (smaller features = more money) * Process yield * Wafer size * Number of metal layers
Speed is more like a side-effect of the geometry, and the geometry affects the silicon area and yield.
It is just confusing to me how 1GB of SDRAM is a lot more expensive that 1GB of flash memory, when SDRAM should be smaller and cheaper to make.
Swap file access will also be faster (arbuably, just installing 8 GB of RAM or whatever might be more economical and effective).
Not to stray to far off-topic, but you got me thinking...
At first I thought that you were correct about it being better to use more RAM, but the numbers just don't add up...
DRAM is just a capacitor and a transistor per cell. Any sort of flash memory is more complicated, as you have to provide programming voltages, floating gates, etc.
So, why is it that 1GB of DDR ram will cost about $40 and up, while you can easily get a 1GB USB drive for $10 or less.
Why the price difference? I thought that since DRAM is the densest possible memory, that it would also be cheaper per bit, but the prices on Newegg tell me differently.
I do realize that flash memory is a LOT slower and will wear out after a few years, but using flash for swap space seems like a very cost-effective way of doing things. As first I scoffed as Vista for doing this, but now I am not so sure.
And that's the point -- everything shows up as files in the sense that they can be operated on with normal utility programs that work on files, like ls, cat, grep, etc.
Does that mean that I can do a cp/proc/proc2 to turn my single-core processor into a dual-core? Somebody should tell Intel and AMD that it was that easy.
Ohhh. The fun I could have copying the stuff in/dev. How many hard drives do I want...

Meesa thinks yoosa prejudiced.
You underestimate the sheer destructive power of Howard Stern's stupidity.
My guess is the helicopters commited suicide rather than listen to him.

Keep waiting. The problem is that if such a system is involved in a fatal accident, the company makin it is sued into oblivion.
Never gonna happen.

You need to raise the joke net, to catch the ones that fly right over your head.

I can just see the defense now:
1) No body, so the prosecution cannot prove that she is even dead.
2) If the IS dead, she recently dated a guy who has confessed to eight killings.
What are the odds that he gets convicted?
