I remember back in the eighties there was a debate about whether an RN with an associates was a professional like a RN with a bachelors was, the biggest difference between the two was the ADN got 24 hrs more nursing, but only 16 hours less total college, eventualy a nursing shortage made the whole thing mote. Now LPNs and aids are doing things that the ADN weren't thought professional enough to do 20 years ago.
Let's see what does ICANN actualy do, well what does it do that we actualy need? It assigns numbers, IP numbers that's realy all we need from them. As far as names anyone can do names, it would take the average unix/linux sysadmin what about 15 - 20 minutes to put their own Domain Name Server online? All they have to do is poll other name servers, example someone types in.aol and the root server says to AOL who is this, its no biggie.
The biggest thing that ICANN seems to be doing is promoting an artificial scarcity of domain names, and speculation in those is about as dead as dodo birds. There are plenty of alternative root servers out there. Start making ICANN as irrelavant as possible and I guaranty they change just to protect their turf
I remember from decades ago (in Byte magazine)the teaching of children what they called turtle graphics, it was basicaly a visual represetion of smalltalk or lisp especialy for kids. This was for kids in the 5-6 yr old range and up, they had great suscess teaching the kids commands to make the tutrles move, to commbine the movements into more complicatated functions lots of basic logical computer concepts. It made sliding them into a more formal language later much easier.
The basic problem is that if the snipit is GPLed then the whole thing is. If you just want a small chunk to steal to paste into a larger work that basicaly comercial in nature and you want to profit off its distrabution then GPL kills you, you're better off with a BSD style liciense.
Sounds like what they realy want is for people to just throw it out there for anybody to use/abuse as they see fit. That's actualy not that uncommon, went was the last time you saw some realy unique javaScript?
A part of the atraction of doing business on the web is the potential to highly automate the process. A part of doing this automation is that machines have to respond to humans conducting legitmate business with the machine, often this requires a confirmation Email to the human.

sweep the suffering under a rug, as it might inhibit support for the war effort. Do show the corpses, the malnourished children and the diseases caused by impure drinking water.
I'm not sure if you're saying that Iraqi children are dieing because Saddam spent all the money he didn't steal on cheap assed soviet era anti-aircraft missiles without G-limiters switches that break in half and drop there warheads in inconvienient places and chemical and nuclear weapon's plants instead of building hospitals, water and sewage treatment plants and food or just the opposite?
some of the German politicians are forgetting their own history I was there from 1974-1977 in the army and I sure that no one there is forgetting their history, Working actively to erase all traces of it yes, but forgetting no. The barracks that I lived in still had swatika's over the doors, other buildings displayed damage from shells fired at them durring WWII. There was a gentle but constant pressure on the US to remove these signs of german history. If you mentioned to a german that you had toured one of the concentration camps their response was usualy along the lines of "why would you want to do something like that for?"
Actualy In light of recent events like the Berlin wall coming down, the fall of the Soviet Union and reunification of the two Germanies; augmented by the rise of the EU, I think that it's time for the US to re-evaluated it's role in the world and especialy NATO. I'm sure that the EU would be able to step up to the plate and run their own affairs. The EU is roughly equivalnt to the US in size and populations, if there is any defense needs that they have and can't fullfill themselves, we're only an ocean away just call. Hell actualy we could defend France remotely, we have enough ICBM's doing nothing that we could make invading France suicide.
I always thought that light hits a flat at anything other than mathematical perpendicular it bend going in and unbends coming out. A flat lens would only be able to effect off axis rays and if the refractive index is positve, the more off axis the ray is, the more it is bent more off axis. if the negative index is valid in optical colors the more off axis the ray is the more it would bent toward the axis. of course if the flat is flat on both side it seems that the effect is undone when the ray leaves the flat.

sound like a real thing not pure simulation also Physicists invent "left-handed" material 24 March 2000
Over thirty years ago the Russian physicist Victor Veselago predicted the existence of a "left-handed" material that would act on electromagnetic radiation in exactly the opposite way that conventional or "right-handed" materials do. The Doppler effect, Snell's law for refraction and other well-known optical phenomena would be reversed in such a material. Now David Smith and colleagues at the University of California at San Diego (UCSD) have made a left-handed material for the first time (to be published in Physical Review Letters). The material is made up of a series of thin copper rings and ordinary copper wire strung parallel to the rings.
Four years ago John Pendry of Imperial College, London, described how a composite copper structure could be used to create a material with negative electric permittivity, and more recently he proposed how the magnetic permeability could be made negative as well. Since the permittivity and permeability describe how the material responds to applied electric and magnetic fields, together they determine how the material will respond to an electromagnetic field. The UCSD team has now made a copper structure that exhibits this left-handed behaviour at microwave frequencies.
As far as getting pulled over for speeding, neutrons routinely travel through water faster than the speed of light in water and it makes a real pretty blue glow.
Where the metamaterial might realy shine is in optical systems by correcting chromatic aberations. Because the speed of light in the lens material varies with the color of the light each color focuses at a different distance(speed of light for glass is 199 861 638 m/s, in a vacuum its 299 792 458 m/s). Optics for photographic use are generaly correct for yellow light and the other are close. Right now chromatic aberation is controled by used a positive lens with one refractive index and a negative lens of a differnt refractive index this requires the focal length of the positive to be shorter and more difficult to make well. If they could make a meta-matrial with a refractive index of -1.5 and a normal glass with a refractive index of 1.5, and both lens were equal the color correction would be perfect. This is one of the reasons Newton made his telescopes out of mirror rather than lenses.
When learning that a neutrino experiment only defected 1/3 of the neutrino's predicted, Issac Asimov said "Either everyting we know about partical physics is wrong or the sun has just gone out, therefore the sun has gone out." At least he was boldly wrong, not everything about partical physics was wrong, just a big part about neutrinos and the sun still burns.
I know of a man in fla who was assinated, he was a Dermatologist, his wife was a OB/GYN who occasionaly did abortions, for patients of record. I guess that the terrorists don't check their lists for accuracy either. His murder didn't make the FBI stats as an terrorist action because he was a Dermatologist, not a OB/GYN who did abortions.

Of course your right I didn't even think of that because I know how extreamly toxic ammonia/nitrites/nitrates are to aquatic animals so I just assumed that they would put it back where they got it from. Why would they install an expensive efluent return pipe. they can just dump it on the surface, and because there is a simalr plant in Hawaii they can still blame the americans
This is a valid command to use when the FBI is bashing in your door and you'd rather go to prison for obstruction of justice than all of the kiddie porn on your primary drive, i.e. it just writes random garbage all over the disk.
also dd if=/dev/zero of=/dev/hda will write zero all over everything, and is also used as a quick way to "format" a drive before installing an OS. such as having a windows machine with a hopelessly corrupted file system, stick in a linux bootdisk execute the command and you'd be absolutely sure that there was no left over garbage. then reinstall you OS of choise.
I'm sure that anything that's over-utilized is going to damage/change the environment in some way. Amnonia is a great fertiizer for plants and any that is not used could be injected back into the efluent stream and would re-disolve as presure and the cold from the depth increases and although it may cause localized concentrations the net effect would be pretty neutral. A little less neutral would be the gradual warming of deep water and its effect on the local deep water enviroment, but the incredible mass of the deep water would mitigate the effect.
Historicaly I've had fun flaming/trolling the enviro-whacko's on/. because they seem to get real excited over win/lose schemes i.e. We lose, enviroment wins; but this seems much more like a win/win. We tend to forget just how precious things like having available energy and fresh water really is. This looks like it will provide a little of both to people suffering without.
Sure this isn't a save the Earth over-night thing but it looks like it's at least commercialy viable
My original post was ment to be a bit trollish, sort of a paradisation of many who will will believe anything that implies that americans have a unique and supernatural ability to destoy the environment.
Actualy I've done some googling and the american car and light truck fleet put out about 64 lbs of CO2 per day per vehicle in 1999, I couldn't find any reliable stats covering the 2002 period.
actualy I'd assume that the curvature of the earth would be significant, a square meter of sunshield at 45 degrees latatude would only be.707 as effective as over the equator, at the poles almost ineffective. So the obvious solution is for everybody to buy a solar pannel and use it to energize a laser to beam the excess energy back into space. Idealy the color of the laser should be one that breaks the mollecular bonds in CO2 along the way.
I read somewhere that the average american automobile emits 2.5 lbs of CO2 per day, whereas the average human being emits an average of 3.5 lbs of CO2 per day. So what do you guess the percentages to be. Wonder how long before the eco-nazi's start advocated nukeing china to save the environment.
Don't flame me because I walk to work. I just don't delude myself into thinking that walking verses driving is somehow a noble environment saving activity.
It took me four tries, but finaly it installed and worked, what a rush that was. Second only to getting kernal 1.2.13 to compile, install then finaly to reboot.
xf86config is likely the most intuitive setup program Not to mention the one you'll have to use when the nice WIMPy sickey GUI stuff fails to detect your card or monitor. Having "cut my teeth" on slackware back when it was either 32bit Linux or 16 bit Windows, having to edit the XF86Config with emacs or vi in terminal mode doesn't give me excess pucker-factor.
how safe is this for the companies? Well considering that their equipment is 22,400 miles a way, and it's all uphill to it; I'd say it's pretty safe. It's not like Iraq could do anything to a satalite, and the bandwidth is pretty much a commodity, so Knocking out the other guys bandwidth is the same as knocking out your own. As long as the providers are playing fair their satelites would be off limits. Now Military satelites a lot of the time are place in polar orbits usualy circular about 600 mi up, still hard to hit.
If you mean how safe is it for ground stations, I'd guess that it's pretty perilous for them. We've warned journalists not to go roaming arround Iraq and try to connect to a satalite.

We show the enhancement of evanescent waves by a realizable negative-refractive-index (NRI) medium consisting of a periodic 2-D L,C loaded transmission-line (TL) network. This network is referred to as a dual TL structure. Growing evanescent waves within the dual TL structure are predicted analytically and demonstrated through simulation. These findings confirm that the dual TL structure is not simply a phase compensator that corrects the phase of propagating waves, but is in fact a NRI medium, since it also enhances the amplitudes of evanescent waves. This structure is a likely candidate for microwave subwavelength focusing and imaging applications. ©2003 American Institute of Physics.
