There is indeed a Soyuz for emergency
You remember correctly.
"A Soyuz capsule will always be docked at the ISS, capable of carrying two people in a medical emergency, or three people in other emergencies. A crew will take a fresh Soyuz capsule to the station every six months."

Sleep and addiction
Here is a snippet about sleep and addiction.
Sleep and addiction
The most important long-term problem is the effect that caffeine has on sleep.The half-life of caffeine in your body is about 6 hours. That means that if you consume a big cup of coffee with 200 mg of caffeine in it at 3:00 PM, by 9:00 PM about 100 mg of that caffeine is still in your system. You may be able to fall asleep, but your body probably will miss out on the benefits of deep sleep. That deficit adds up fast. The next day you feel worse, so you need caffeine as soon as you get out of bed. The cycle continues day after day. This is why 90% of Americans consume caffeine every day. Once you get in the cycle, you have to keep taking the drug. Even worse, if you try to stop taking caffeine, you get very tired and depressed and you get a terrible, splitting headache as blood vessels in the brain dilate. These negative effects force you to run back to caffeine even if you want to stop. -
Re:Great...
I don't understand the combination of "hypersonic" and "space plane." I thought the key behind the US hypersonic plane was its ability to compress and use oxygen to increase its speed and function.
Here's a couple of links that compares and contrasts these two.
I don't understand the way the combination of the two would work.

Re:Love the quality reporting
Not to mention that he brings up fuel cells in the article/ad:
"Long-term fuel cells that convert hydrogen and oxygen to electricity -- don't ask me how -- are a promising alternative."
Notice that he neglects to go into any basic details on fuel cells. I found this link by doing a google search on fuel cells.
It would have taken him very little effort to come up with a one or two sentence description.
Damn lazy journalist. -
Re:Is it pre-programmed to do anything?
OK, you seem a lot better informed than I, so:
Why exactly is the clock an expected point of failure?
It seems to me that a super-sturdy clock is the smallest of challenges in a mission like this. I'm glad they considered the possibility of its failure, but can you or someone please clue me in as to why the clock of all things is so fragile?

Re:Forgot insulation
What if we keep the high voltage idea and simply mount a power grid ?
He sure can drive to the nearest Toys-R-Us and buy a "My First 765kV power grid" junior kit, with all poles included. A 765kV transmition line is enough to supply 3.8 GW for a 100 miles distance (dropping to 2.0 GW if the distance is 400 miles).
The coolest thing with high voltage is that you can buy, in this same store, the infamous "Frankestein kit". It's basically a brainless Frankestein. You just have to find a brain that nobody is using.. I suggest you use the one from a 419 scam victim, as he probably won't even notice his brain is missing.
Ultimatelly, you could also run your very own nuclear plant. This should be enough to power your computer. But it's much harder to do. First you have to consult your local terrorist organization on how to get some uranium, and then your local mafia on how to deal with ambientalists. -
In your defense...
English-readers can find Wage Statistics on Norwegian government officials here, where you would find the Average Ministry Salary in 2002 was 30,200 Kroner, or about $4,260. There is a footnote, however, indicating that costs of health services are not included.
Interestingly enough, I ran across this through Google: "I do not think any job is worth 10 times a prime minister's salary," said Minister of Finance Gudmund Restad (Centre) when asked about Tormod Hermansen's NOK 7 million salary.", where one could infer that the prime minister's salary is ~700,000 NOK, or $102,734 on 5/20/2003, the day of this report. By comparison, Pres Bush's salary is $400,000 (raised from $200,000 by Pres Clinton in 1999, the first raise since 1969).
Personally, the salary levels in USA's government are outrageous, given the rate of increase (or lack thereof) of the common person's salary. My personal political beliefs align with the Republican party, who used to represent reduction of government... and recent budget bloat really concerns me... And you are correct, our cultures are vastly different. I for one, do not understand how you can have a political party called the "Christian People's Party" who can expect to remain neutral on affairs of church & state. It's also discouraging to me that the average Norwegian citizen cannot differetiate between the concepts of capitalism and greed; there is quite a difference between valuing and rewarding the risks and contributions of individuals, versus rewarding administrators at obscene rates for playing numbers games and bending rules for personal gain. -
Re:Drove through this morning.15 billion dollars is about what americans burn through in gasoline in 42 days. At least you have a highway system to show for it.
Now you want to talk about wastes of money. Philadelphia just built 2 new stadiums for about 1.2 billion dollars. I wouldn't mind, save they the schools are chronically short funded, the new stadiums have half the seats of the old stadium, and nosebleeds cost $60. No one around here can afford that on a regular basis.
Bitch all you want about Boston wasting your money. You got infrastructure out of the deal. All we got was a stay of execution until the next time our sports teams want to play hardball. Damn it, and we had just paid off Veteren's Stadium...

Re:That's itSo we need more room, the island won't cut it for long.
So build more floating islands instead. 70% of Earth's wet surface area hasn't been claimed.
Okay folks, here's the plan: we live on the island until we perfect space travel and terraforming, then we go grab one of those other planets that no one's using right now.
And here's my plan, Oh Great Leader: we live on the island AS technology continues to advance exponentially anyway, thanks to ~6 billion interconnected minds feeding off each other ("IP" anti-progress be damned), then we move to a self-sufficient, offplanet island as soon as possible in order to minimize the chances of the The Great Filter wiping everyone out. In the unlikely event that planetside humanity doesn't wipe itself out, then tech will continue to advance to Singularity in short order, otherwise, progress will come to a standstill and we'll be spam in space island cans for quite a long while until we screw like rabbits to get our brain-count back up.

Re:Bandwidth limits?The issue with cable and uploads is that the FCC won't allow transmitters of more than a certain power on cable television lines w/o a license. When you upload, your cable modem is using its builtin low-power transmitter to push the data onto the wire. The cable company's central office does have an FCC license, so they can broadcast a much more powerful signal down the line to you, and in fact just broadcast everybody's downstream packets on the same channel (so in the past you could sniff the network and see anyone else's traffic, but they have added a little bit of logic to prevent that). The problem comes when multiple customers are trying to upload at the same time, each with their weak signal. In order to prevent multiple transmissions from colliding with each other, a time slicing multiplexing scheme is used. In other words, each cable modem attached to a given central office (Cable Modem Termination System, or CMTS) gets a certain time window to transmit. Quoting from How Stuff Works' article on How Cable Modems Work:
The downstream information flows to all connected users, just like in an Ethernet network -- it's up to the individual network connection to decide whether a particular block of data is intended for it or not. On the upstream side, information is sent from the user to the CMTS -- other users don't see that data at all. The narrower upstream bandwidth is divided into slices of time, measured in milliseconds, in which users can transmit one "burst" at a time to the Internet. The division by time works well for the very short commands, queries and addresses that form the bulk of most users' traffic back to the Internet.
A CMTS will enable as many as 1,000 users to connect to the Internet through a single 6-MHz channel. Since a single channel is capable of 30 to 40 megabits per second (Mbps) of total throughput, this means that users may see far better performance than is available with standard dial-up modems. The single channel aspect, though, can also lead to one of the issues some users experience with cable modems.
That is why uploads with a cable modem aremore limited than downloads. -

New Zeland acts really disappointing
How could one stop research in so important area of science called rocket engines?
How a government could to that?
There seems to be some kind of plot in it
(from Bruce Simpson's page):
The strange thing is that just a matter of months ago, they told me I could export the very same technology to Iran -- despite the fact that it is widely considered to be a terrorist sponsor and similar exports are prohibited in the USA.
And then the government decided shut it down.
Note also that israeli x prize team recruits serious brainpower.
If things are not about money (or sex) then politics must be involved.
I hope that such a genius person as Bruce will either join Xprize or find another way to continue his very important for science work on rocket engines. -
Re:Too many scifi movies
So this must be pure science fiction? And this research is also fiction, then? If not, then laser energy can superheat air and cause sound problems. Why would it be so ridiculous for me to think a laser the size of a basketball hoop might not have the same effect? (Of course, if I had RTFA more carefully, I might have seen the energy reference -- you're right, it's small-scale.)
Why does air have to be turned into "superhot plasma" to make a sonic boom? A supersonic jet doesn't superheat air, per se, it displaces it. A nighthawk doesn't superheat the air, but produces a sonic boom with its tailfeathers.
And since when did anyone say anything about outer space? The event is happening in Colorado. (Not far from outer space, actually, but...)
And you don't have to be a jerk about how incredibly knowledgeable you are -- we get it without the barbs. -

Re:Unicycle riders can tell you...
No, but don't you see? There's a spinning gyroscope INSIDE the wheel hub that helps provide lateral stability. If the gyro is spinning fast enough, the device will have extreme difficulty tipping to either side at all, allowing the rear/front stability. (View the flash animation, and then visit your local children's museum and play with the bicycle tires you can hold while spinning)
This leads to the assumption then when turning the vehicle, the gryos slow down allowing the device to lean, and that leads to the question: How does it know if my lean is to turn, or if I'm falling over and corrections should be made in the gyros?
You are right about one thing, though. I don't see a physical way for it to rotate the tire beneath the rider the one way does on a unicycle. Is leaning the only way to turn the device? Even at low speed? Low speed turns would require more lean to turn the vehicle, and if more lean is allowed by the gyro, there will eventually be a point reached where the gyros can not recover, regardless of how fast they spin.
Remeber! Gyros can be used either as active stability devices or sensors. They arent' limited to one or the other. -
Re:Nothing NewGM also came up with the "skateboard" design,
I bet it's not as cool as the BMW Streetcarver. I want one, but no doubt I'd just write it off with my dismal 'skillz'.
Seriously, I would love some kind of powered skateboard, as they're very good for getting around tight parts of town ( and being able to pick them up is very convenient... ), but they're going to have to make them very easy riding ( perhaps with that suspension system from Snow Crash ) before it will ever take off with the masses.

YOU need a review. And new glasses.Taking things slightly out of order (I do not suffer fools gladly):
the word 'conductivity' refers to a property of a material in respect to how it behaves in relation to electromagnetic engery, so I don't see this as being completely off the wall.
That's the kind of hand-waving explanation I expect from people who have no understanding of what they're talking about. Scientists and engineers have quantitative understandings of such things, down to the fundamental units they're working with. FYI, conductivity is the inverse of resistivity, and for bulk materials has the units of mhos per meter (for a conductor of uniform area you multiply by square meters of area to get mho-meters, then divide by the length in meters to get mhos).let me put you straight on some of the mechanics of optical/holographic memory. Firstly, it doesn't employ a rotating mechanism...
My cursory examination of your example shows that it does indeed demand a rotating mechanism, to change the angle of the recording/playback beam relative to the medium.Your default posting score of 0 appears to have been earned justly.
Lastly, by saying that hard drives do not last long enough to be affected by events that happen in 'geological time' is an assumption. There is nothing to tell us for certain that the Earths' magnetic field will not flip tomorrow or next week, or next year. This is a real possibility within our lifetimes...
The same laws of physics which create the earth's magnetic field (magnetic induction) prevent it from changing rapidly. If you'd bothered to do even the most trivial Google search on the topic (I used ``earth "magnetic field reversal" ' '), you would have found this NASA page. A quote from one of its pointers:Is the Earth's magnetic field changing?
Needless to say, this rate of field change is no threat whatsoever to magnetic media of any kind. A 7200 RPM hard disc can already see the Earth's 0.7 gauss field reverse itself 120 times per second (assuming it is oriented correctly), and this poses no difficulties whatsoever for storage. The idea that a change requiring 4000 years would be a problem for your HD is simply preposterous. The first search result also debunks any notion of sudden or tragic results.Indeed it is. It currently has a strength at the Earth's surface of 0.6 Gauss. But long term observations show that it is DECREASING at a rate of about 0.07 percent PER YEAR. This means that in 1500 years from now, it will only be about 35 percent as strong as it is today, and in 4000 years it will have a strength of practically zero.
As for your fear of people with mod points who find comments interesting...
I'm not afraid of them, or you. I fear for the future of this society, because people like you and they actually think you understand these things well enough to claim an opinion on the matter. As even the most trivial of attempts to educate yourself would have given you (or the moderators) authoritative information to the contrary, and as Slashdot users are selected from probably the top 10% of the population, this should worry everyone. -
Re:Someone needs a review of science classYou can call me ignorant if you like, but let me put you straight on some of the mechanics of optical/holographic memory. Firstly, it doesn't employ a rotating mechanism. See here how stuff works, it's not a complete explaination, as I can't find the IBM research papers, or the original Byte articles online. Secondly, the word 'conductivity' refers to a property of a material in respect to how it behaves in relation to electromagnetic engery, so I don't see this as being completely off the wall.
Lastly, by saying that hard drives do not last long enough to be affected by events that happen in 'geological time' is an assumption. There is nothing to tell us for certain that the Earths' magnetic field will not flip tomorrow or next week, or next year. This is a real possibility within our lifetimes, just like the planet being hit by a meteor, or a mass of ejected solar material - and a lot more likely (and preferable in my opinion). The energies involved are colossal and are equivalent to massive EMP on a global scale. When the magnetic flux of the planet reaches a chatoic mode it can happen quickly and continue to flip rapidly for a very long time.
As for your fear of people with mod points who find comments interesting, I suggest you take a walk outside in a park of something and take some deep breaths to help overcome this fear

Re:Sadly, you got your facts all wrong...
One correction. DU rounds do burn as they hit - chemically burn by combining with oxygen in the atmosphere. One of the benefits of DU as opposed to, say, lead, is that this burning "sharpens" thr round as it penetrates, so that the momentum is still concentrated over a small area, instead of squashing flat and dissipating its energy over a large area. To contradict you, I don't think DU is particularly hard - but this self-sharpening effect means that it doesn't matter. It is increadibly dense: much much denser than hard materials such as titanium This increases the penetrating power of DU. See here
The downside is that this means that the uranium ends up as finely divided uranium oxide which, for purely chemical reasons, is very toxic and has no breakdown mechanism. On particular, the wrecked target vehicl is highly pollited and should only be entered with protective gear. However, they temd to be left in the countryside after the war for gawpers - particularly children - to climb all over. -
Re:Moon mining no, asteroid mining yes
Mining itself does not make sense as a first step. The first step is power generation. We need to place a few microwave transmitting solar power stations into orbit first. Then we could use some of that energy to drive lasers that would push materials into space at a low cost. Then we could use those technologies and materials to build bases to mine from.
The benefits of this sort of progression is that when the power satellites are not being used to push spacecraft they can be used to generate almost 100% clean energy with no chemical pollutants, particulates, radioactive waste, damming of rivers, or CO2 emissions. The power stations would pay for themselves quickly and would actually have the space program generating revenue rather than just being a cost. -

Re:Data crystal...
This will be worthwhile if for nothing else than finally giving all us nerds the "data crystals" we have always wanted from various crap sci-fi...
Data crystals are based on holographic data storage. Holographic memory has the advantage of preserving vast amounts of data throughout the volume of the crystal, not just on the surface, plus if it's chipped or broken each piece still retains the entire holographic image. It's completely different from any data storage method used today, including this one.
For various reasons, mostly cost and implementation, holographic data storage has never materialized. You can read a little more about it at HowStuffWorks and other places. (I googled for "holographic memory data storage" and found that page at the top.) -

Re:I wonder if...
Outlets in the US are 120 volts DC. FYI. And your lightbulb example is hogwash. Lightbulbs will burn out no matter what.

Occassionally it will superheat and boom, light bulb goes dead.

Re:communicating?
Ok, smart guy...
I admit, I was wrong about the deep space listening network. (opens mouth and temporarily inserts foot)
Taking foot out now...
1) If Voyager is passing out of the Solar System into a region of space that has less material than the greatest vaccuum man has ever made. This means there's virtually nothing to interfere with signal transmission out there. Meaning there won't be much signal degradation once it passes this barrier
2) Signal attenuation due to distance is on a logarithmic scale, meaning that the further it gets away, the signal loss in dB is less and less. Again, meaning there isn't going to be much signal degradation for the next 17 years.
3) Offtopic slightly but, Since the antenna on Voyager is directional, the more out of whack it is over there, the less chance you have of getting signal to and from. Bigger antennas aren't going to help if the signal is hitting the antenna from the wrong direction. Anything done on Voyager's end would have lots more effect than anything done here.
Here is a link to a free space loss calculator. What it would show you is that the scale of free space loss in logarithmic. EG. Attenuation of signal is less and less the further it gets from Earth. Try taking a look at the difference in signal loss between a trillion miles, a billion miles, and a million miles. There are only going to be about 6dB of signal loss if Voyager doubles its distance in the next 17 years.
Here is a link about Voyager and its 23 watt radios and directional antennas.
In essence, building some really big antennas down here will do just about dick. You can try and paint me as numbnuts, but you'd be wrong. -
Intrusive and over-complicated
Much simplier approach, which is widely used here in Canada and
in the most of Europe, is to embed sensors in a form of loops of wire
into the road on each side of the intersection. The loop can sense
the car directly above it, which allows streetlight controller to learn
the length of the line-up on every side and switch the lights accordingly.
Simple design rules :) -
Already done.
They already do that. They're called proximity detectors, and they determine when cars are sitting on top of them. They work based on induction.
Sometimes you can see where they were embedded in the road, especially if the light was retrofitted. Look for a patched-over hole in the pavement directly underneath where the first car would pull up at a stop light.
That is why some lights only change when your car is sitting there. For additional fun, you might be caught behind some dingus who, for some reason, stopped too far back to trigger the sensor. You're going to be there a while. -

"Low Carb" is the new "Low Fat"
Remember when "Low Fat" products were all the rage? The only problem with "low fat" is low fat usually doesn't mean low calories... Take Snackwell cookies for example, low fat doesn't mean shit if you're planning on eating the entire box in one sitting. Low carb is just another trend that is totally meaningless if you think it keeps you from counting calories.
The only reason diets like Atkins work at all is simple: just about everything has carbohydrates in it! There's so few things you can eat if you strictly adhere to the diet that you inevitably end up eating LESS CALORIES.
Howstuffworks has an excellent article on dieting and the gist of it is, you guessed it - limiting your calories consumed.
If you are willing to tolerate counting calories and figure out exactly what you need to maintain your desired weight, you can pretty much eat whatever you want. 100 calories of carbs = 100 calories of fat. If you're the type of person that needs a "banned foods"-type list to really feel like you're on a diet, Atkins probably is for you. If you're the type that can push away from the table - you probably don't need to do anything more than watch your calories. -
Re:Reminder of the original purpose of this holidaCare to explain how a 2000 year old religion such as christianity could have 'just swiped' observances belonging to a pseudo religion like paganism with roots in the 19th century?
Actualy, they swiped the Samhain holiday from the Celts who were around since 800 B.C. From the entry at howstuffworks.com:
Originally, Christians observed All Saints' Day on May 13. But in the eighth century, Pope Gregory III moved it to November 1. Officially, the Church chose this new date to mark the papal dedication of a church honoring the saints. But many historians believe the Church really moved the observance to correspond with Samhain and other pagan fall festivals.
That's how.

Is the SLR mechanism still really useful?The household name "SLR" is usually associated with more expensive cameras with manual adjustment possibilities and exchangable optics and so on. But the SLR mechanism itself is just the mirror arrangement which makes it possible to use the same lens for the viewfinder and the film. (Thus the name Single Lens Reflex) When the shutter is released the mirror moves away for a brief amount of time while the film is exposed. See howstuffworks for an illustration.
But is this mechanism really needed on a digital camera with a good LCD viewfinder? Doesn't it just drive up the cost and complexity of the camera? Also an LCD viewfinder has at least one great advantage over the optical one, since it shows you how the final image would be exposed. I can't really see any merit of an optical solution if the LCD resolution and quality gets good enough.
So, in short I think the SLR in "SLR" is overhyped. Give me a digital camera with good manual adjustment possibilites and exchangable optics, and I would be happy!

But wait, there's more!
For example, "goop" gets fed to a cracker (catalytic or thermal) which (oddly enough) cracks the C20's into smaller pieces. While one typically aims for the the gasoline range as the max product out of cracking units (assuming that's where the money is), going down to C1-C2 is not difficult - you just have longer catalyst contact times or higher temperatures.
If you want more info on "goop" & light, sweet, yummy oil, go here for details!
I'm not sure how far you can reduce the goop ... that is, can you eliminate all your C20 into ethylene et al? I'm not sure you can, because the c20 goop is sold as coke, which I daresay is cheaper than gasoline. Why do they do that if they don't have to?
Please enlighten! -
Re:Hydrogen fuel cells
The separated hydrogen and oxygen are just portable forms of energy... a clean energy. They burn together, and the output is water vapor.
Described here. Do you know how fuel cells work?
They use a simiar process in rocket engines using liquid oxygen and hydrogen. -
Re:They should watermark them.
Lets see...
The Blur is 5 minutes and 30 seconds into the movie, that means that member X leaked this film...
I guess you could remove a few frames to change the time stamp though =/
but if the watermarks are placed at 5,8,10 etc minute intervals it may be hard to remove.

A common misconception is that there are just these ~10 'Academy Gods' that grant worthiness to movies. The academy is a semi-diverse group of over 5000 members in the film-making industry. -
