The Water Bureau of the City of Portland went with the lowest bidder for a replacement to their billing system. The bid was for 1 million; it has now costed the city over 7 million, and the damn system doesn't work right. Thanks STS.

This is true, so the real future of computers will be a hybrid between quantum and conventional computing. It still will be a pain to write the software fo it.

No, it has to do with the number of listeners.
if there is only one transmitter, and one receiver, The data only flows one way; when another receiver is added, it changes the message becuase it's there. It's difficult to explain, but you should find some good books listed with the website above to help you out.
Here is a paper I had to write on the subject; it is in draft form as the class did not call for a final version. Quantum Computing
I know, I posted this in my thread too. Oh well, I have karma to burn. Besides, I feel this is important enough to bring it to the top.

Acutally this means we need to change our encryption methods. Most encryption is based on factoring large numbers, rather than new and wonderfully complex encryption methods. Also for communications, quantum computing adds extra security in that if someone else is listening to the message, they alter it, thus rendering the whole stream useless.

I thought that this might be interesting for a few of those who don't know much about quantum computing.
The idea is to have a bit that can be a 1 or 0 at the same time. This means that with 50 bits, called qubits, you can represent every number from 1 to 1 trillion, at the same time.
What's really cool, is with this you can use what's called a bogo sort. Imagine a set of cards, that is shuffled. Now to sort them in order, most people would go through 1 by 1 and put some in front and some in back. A bogo sort creates a new universe and then throws the cards into the air. If they land in order, great, else destroy the universe.
All these universes are created at the same time, making it 1 step to sort 52 cards. Like I said, it's interesting.
Ah, there is a problem with your logic. The idea is that software can tell the diffrence between two diffrent carriers. With searching for any signal, you don't need the software. Thus the seti project is still valid.
This article, I feel is more than a little vauge. What did they use to transfer? Was it just over electrical/telephone lines, or did they use optics? What kind of compression was used, and what kind of signal boosters/optical repeaters were used in sending this. All of these items could be used to affect the speed of transfer, and well, the article just doesn't say. I mean in theory, one could build a router from parallel to serial that could take data at 9.6 terabits/sec. How are they actually measuring things? Just the time between there and here? Using full optical lines, wouldn't they be able to set the record at c * the index of refraction of the fiberoptic line? It would just be a matter of putting all the data into one block of light.
Also the article suggested only one way communication, what happens with error checking and such?
Bud, I don't know what your talking about. I'm running RH 7.2 and Evolution. I had to configure the palm in the system settings of gnome (which is individual to each person) and away it went.
Perhaps you need to look into the setup a little more.
So I get this call at 7 this morning (pissed me of becuase I don't have class till 4 pm) guess what. A family member has this virus becuase her company didn't bother updating the Microsoft products and she has auto-preview on, even though I've told them not to do that. They thought they were protected becuase the company scans all e-mails for viruses through out the network.
What's the lesson to be learned? Even if your company has the best virus software, it's always 2 steps behind the viruses. Update your ie and outlook already, I mean the process takes about 15 minutes and two restarts on a fast connection. And don't call before noon on Tuesdays! I like my sleep!
The interesting thing that I've found, as I run WineX and play Counter-Strike/Day of Defeat through linux rather than windows, is two fold. First, I've found that the program doesn't crash, Windows isn't running and cannot fubar the program. I've also found that the engine gets better performance than in Windows. Part of this is the kernel drivers for my graphics card, but part is that using the Linux API gives better performance. (W.ine I.s N.ot an E.mulator [Wine is an implimentation of the Windows API in Linux])
[rant]I'm sorry, but as a student, this kind of stuff drives me nuts. I work for every grade I get. I stay up nights working instead of drinking. And then to find out that someone else cannot earn their grade. As I see it, this is just a company making money off of people, and if it becomes profitable, they will sell the work they've done for you to your teacher. As a student, it's not worth it.[/rant]
On a final note, is this what Microsoft is so worried about with GPL?
Your second point has a flaw in it, M$ does not offer it's products to students for free; however, linux and all the development enviroments you would want to use on it, are free.
They're going to have to make a MAJOR mistake before anyone else comes along to take the lead.
Wouldn't this mistake be XP?
Okay, that was a cheap shot. But, with having cs students, who will be joining companies as programmers, and then moving up to managers start to shift this industry standard?
I might be mistaken, but I believe, just about any major company develops on unix/solaris anyways; it just makes more sense when it comes to writing code, to do it on a platform that is stable.

Go with the lowest bidder?
How does M$ expect to beat free?

How did I get redundent when I was the first to post this?
I've heard of people being able to spoof mac addresses. I think you may need to watch out for that.
Also education of the tennets will be needed. You don't want them to come running to you because the hotmail server went down.

Didn't they have something like this in simcity 2k? I only ask becuase things didn't turn out well when it missed.
I had something similar when I switched to linux. I guess it's all that mounting hard drives, and fingering users.

half a million hand helds will mean that the tech industry will have a nice (even if it's small) boom.
Of course not..... I see apple as creating the first computer without a monitor, hard drive, modem, or cdrom. It's based on telepathy.
I'm hooked on anime.
I blame it all on Toonami.
I've spent all day watching cowboy bebop.
I remember this stuff. Don't they use it in national lampoon's christmas vacation?
I only ask becuase things didn't turn out good for clark when he used it on a snow disc.
Something to keep students from thinking.

If GPL is as bad as Microsoft says it is, why do they keep drawing attention to it?
I mean, come on, when you continue to talk about something, the idea survives, where as if you ignore it, most of the time, it will just go away.
