3/4 Billion dollars to vacinate millions of people might sound a great idea...... But think of what might be the implications...
Firstly, there is already a child mortality rate..... This program will decrease this rate, so more children live... If so, we will need more Food/space to feed them? Will we end up in 10 years or so with mass hunger, with exponentially more people dieing of starvation, or with more and more forrests cut down due to a rapidly increasing population?
Also, What would be the effect on the Vaccination? Using it this many times, I would imagine that the diseases it protects against may grow immune. So, this would leave us with no vaccinations.... and in 10 years time, us in the western world might end up dead when untreatable plagues run riot....
Of all the things to help those without, I just think that this idea has not been well thought out.
By you're website link, I guess you're much better at QM then I am. So I presume I'm not thinking QM Enough..... So I shall ask you this.
If it is how you say, then What is the Polerisation of the photon, if it leaves Alice with Polerisation of 0 Degrees. Is it 0 Degrees (ie, 100% certain it is 0 Degrees) or, does it become a qbit with a varying percentage probablility it could be polerized to anything other than 90%?....If the latter, what made the photon go from a 'certain' state, to a quantum state?
The photon sent by Alice is 'Encoded' with a '0' by been polarized by either 0 or 45 Degrees (Alice would ensure that this choice is made at random), or a '1' by been polarized by 90 or 135 Degrees (Also, at random).
When a photon arrives with Bob, Bob can either test for the polarization been 0 or 90 degrees, or 45 and 135 degrees..... But, (and this is the the crucial point), not both..Bob either tests for 0/90 or 45/135 degree at random. If the photon initially left Alice with 0 or 90 degree polarization, and Bob tested for 45/135 degree polarization then the photon would be 'forced' into adopting either a 45, or 135 degree polarization, and the initial polarization would be lost....- there can be no second chance at testing. When Alice and Bob negotiate later on, they can determine these are the bits to ignore.
The point I'm trying to say, it is impossible to determine the polarization of a photon to be one of 0,45,90 or 135 degrees in one go..... If it was, then Eve could hack the communication. Only 0/90 degrees, OR 45/135 degrees.... Not both.
I accept your correction for the other point - Alice and Bob would have to negotiate with each other to find out which bit's were 'Lost' rather than Bob would informing Alice of the photons he was able to read. Bob wouldn't be able to tell if the '0' or '1' received was an 'error' or not, without determining that Alice was transmitting in the same 'basis states' as he was receiving.
Not true. While there may be limitations in his measuring apparatus, there is no theoretical reason why he could not successfully read 100% of the photons.
Check your Quantum Physics!... If bob could successfully read the polerizations of all photons, then So could 'Eve', and therfore create an identicle photon stream to bob, and bob would know none the wiser... Quantum encryption depends on the fact that only 50% of the polorizations can be read.
Alice sends Bob a stream of photons. Each photon that is sent, Alice encodes a state of '1' or '0' on each photon.
Unfortunately, Due to Quantum Mechanics, Bob only has a 50% chance of actually reading the state of the photon. 50% of the time he gets '0' or '1', and 50% of the time he gets 'Unknown', and the photon is destroyed.. This is ok, because after receiving 1 million bits, Bob phones up Alice on an unsecured line and says I managed to read photon numbers 5,6,9,12,13,16....(+ approx 500,000 more), so I will use the state of these photons as a one time pad. Alice looks up the states she sent these photons, and now both parties have a one time pad to encrypt data.
Now, lets say there was an intruder attempting to intercept the key exchange. The intruder is also constrained QM, and can only read 50% of the photons, with the other 50% Destroyed.
Because, the 50% of photons the intruder would receive, would be different to the 50% bob had read, it is impossible for the hacker to use the information sent using by bob to Alice, via the unsecured phone call, to build an equivalent one time pad.
Also, as the intruder is only able to forward a exact copy of just 50% of the photons to Bob, with the other 50%, now destroyed. He could replace this 50% of photons with his own set of random state photons, but this will be detected by Bob and Alice, as the one time pads would be different on this 50%, and the transmitted data using the pads would be corrupted.
About 15 years ago, I was a BIG tertis fan, playing it at any opportunity I could get on my amiga. Though it got to the point I saw, and played the game in my dreams while asleap.... aghhh.... and non of the pieces fited either.....At this point I decided to cut down a bit!:)
With laser precision, LightScribe delivers a closely controlled quantum of light energy to multiple points on the disc as it spins in the drive.
So I presume, the image on the disk only appears when someone finally observes it, and before, it exists only as a superposition of qpoints..... How Cool it that!;)
Ok, off the head design.... (I'll have to get some Lego).
1) Rotateing axle power input into gate, with medium cog rotateing freely...
2) Axle for logical output... with medium sized cog near to power input cog, but not connected
3) Power input is coupled to logic output via fairly loose rubber band - output will turn in unison with power input, with no other parts added.... both input/output cogs will be turning same direction
4) Add one logical input.... This will be connected via rubber band to a mechanism to shove a cog inbetween the power input, and output cogs, engaging, and forceing the output axle to reverse, as cog drive will not slip unlike the rubber band drive. If the logical input is rotateing one way, the cog will engage, If the input rotates in other direction, cog will be pulled from between power input, and output, and so both will rotate in unison again
.... Means, like what already has been said, that after a few gates, the movement (and therefore the on/off state) deteriorates to nothing. However, this is exactly what would happen in an electronic circuit, if said circuit was built like this (Inputs and outputs only, no Power). Now I'm wondering, if it is possible to add a third rotating input to the gate, for power, so the logical output was of the same (or better quality) of the inputs....
500,000 beta testers!.... Wow!.... The only problem I can see, is, just as a city becomes more lonely the greater the population, I only hope these super MMORPG games don't loose the
magic of meeting, and making friends with people you meet time and time again.

Look here for the 'Simple Text protocol'. Hell, When I was cutting my teath on a VIC20, I could have used this to interface the GPS with that, using Commodore BASIC. (assuming I had a RS232 Interface!). This is very simple stuff!
it's probably safe to assume that the good folks over at Garmin would say something along the lines of "Lih-what?".
This may be the case, however, they are very open with the interface/communications protocols for their GPS's - If you go here you can download documents detailing the protocols in a platform neutral format, meaning that anyone with just a little programming experience can easily make programs to interface with their GPS's, on any platform, Linux included. To be quite honest, I can't think of another hardware vendor, that is so open with the specs. Usually, Companies require you to jump through hoops (NDA agreements/ etc) to get hold of this information, or have to resort to reverse engineering, etc. And, if you can't/dont want to program, then there's a few projects already made for you on sourceforge!
To sum up, Don't knock Garmin, They might not produce Linux drivers, but at the same time, they do go out of their way to make it easy for others to do so should they want to.
A Friend who I work with has one of these wireless video baby monitors.... And he himself has said, you end up repeatedly running to the nursery 'cause it looks as if the babies far too still when viewed on the little LCD display.
So, I guess what would be useful is a button on the monitor, that when pressed will give the baby just a little electric shock, to cause the child to move or flinch enough to be seen over the LCD;-) (just kidding - honest!).
Yes, why not!.... It could be possible to dynamically update your website using phptunes, so (in theory) your online music site will not need any maintenance!
Link directly from your website to any song, album or artist on iTunes. iTunes offers the largest and most diverse legal music download catalogue -- over 1 million tracks from all five major labels and over 600 leading independents.
So... Lets say I copied all the available tunes titles from the itunes store, and launched a kickass amazing sites that was more friendly than iTunes , easier to navigate through. (If this is indeed possible, is not the issue here). So, My site becomes a instant Google like hit, Consumers are happy (iPod compatable song downloads), I'm getting 5% of each tune that is sold... (5% of millions, is, well Loadsass!), so I'm happy also.
So, what would be the difference (not technically, but Visibly to the consumer) between this setup, and Apple [doing what everyone's screaming at them to do, but they won't] licensing the AAC technology to a third party to allow them to set up their own store?.....
in the latter case, To get the protected AAC files to your iPod, you still need iTunes (to handle the drm keys), So Apples presence will still be there.
How much differences will there realy be?
That may be true, however, it's still pritty snappy. on my Pentium 1.5 Ghz, I can still open 20 or so windows (JFRames), with a few fields/buttons/dropdowns in under a second. This is quick enough,
