In WDM (I'm not sure the acronym is right) what you do is send more than one signal by using different light colours (frequencies) that don't interfer with each other. What you do here is send two signals that have the same frequency but orthogonal polarizations so they don't interfere to each other either; imagine one of the waves going on the vertical direction while the other goes horitzontal, that would be orthogonal and you could recover both the vertical and the orthogonal one independently.
You are right, SMS are 160 chars long and we use it _a lot_, but I just tried using different fingers in my phone keyboard, I don't like it at all, it is not comfortable! I think that the predictive text input used in many phones is great, you can type really fast, I doubt that a much faster rate can be achieved with the new method. Still, I type much faster on my computer; something that gets me to that speed would be great, maybe voice recognition!, but this one is not that good.
What someone should do is create a standard, so anyone could use whatever software conforms to the standard with whatever server is ready for it.
I'd rather prefer the IETF working on that kind of things than the oh-so-powerful AOL deciding who (MSN?) do they allow to be compatible. Still, even if it is not what I'd prefer, it is nice to see I will not need MSN + ICQ to be able to chat with my friends on the two sides in the close future.
I forgot... even with all of this, I don't see how it is possible to file a lawsuit agains some other company because they stop using your service... ?
Will "Golden Burger" take me to court if I change to "Burger Free"?
I contributed some lists to CDDB because they were providing the data for free to everyone, now that they changed the conditions, I will have to ask them, remove my data!. It is not fair, they build their bussiness based on free submissions from users because we thought that the database could be accessed for free, everyone is fooled, now the database is big and they go and charge for its access. They argue that the value is in the software that manages the interface: wrong! That same database interface beeing empty is worth nothing. What is not fair is to change the conditions, I will ask them something, create a new company, call it Gracenote2 with this very nice interface to a new empty database and start over again, I am sure that you will have as much submissions as before this time that users will know the new conditions and soon you will have the same data than before, with a slight difference, now your bussiness will be completly legitimate in my point of view.
Well I don't know, still I am not convinced by this assertion that radio bandwidth is infinite.
While it is true that in CDMA the important thing is to separate the desired signal from all the others (that can be seen as interference that looks like noise), still, it is not _only_ a matter of processor power to achieve high bandwidth but other things should be taken into consideration.
Air interface has a lot of problems (like fading or shadowing) that are difficult to solve even if one could use all the wireless bandwidth, because then other things like problems in antenna design or in RF circuits start to appear.
But if the point of the book is that the usable bandwdith is increasing, then I totally agree, only that, given that we want more and more bandwidth-eager applications, it will still be many years since we don't need to increase our bandwdith.
I should read the whole book before giving a well-founded opinion about it.
But taking the risk: one of the trends (at least in Europe and most of Asia) seems to be wireless networks and using these wireless networks for everything included carrying internet-traffic, and even with all this new capacities of fiber optics, still, there is a limited (short) bandwidth of the radio spectrum that can be used; I can't see how this is going to change in the future.

I am an EE student and have been working in group for many years now. Usually on labs (2 people, 3 at most) were you need to get some results at the end of the session. I can tell you that still now, I am amazed on how well it works, many many times it happens that before the LAB session neither my partner(s) nor me have any clue on how to do it and don't feel capable of getting anything; but it happens very often that the pieces of knowledge that we both have add up to the knowledge needed to solve the given problem.
At the end, we get a good solution, and we both learned from each other.
Also I've been working in group projects and I really think it is worth it, usually they require quite a lof of thinking (and not easy) and sharing your thoughts and explaining your points helps in understanding better the problem and reaching a right solution; many times one thinks in one way about a problem, and when sharing the ideas with your group some difficulties in your reasoning are found, or improvements, or maybe a new different approach.
The main importance of group working is that the strong points of all the partners are added together. Of course that there are drawbacks: the main beeing having bad group partners that are not at the same level than the others, then they cannot add to the group.
I guess it helps the patient rather than disturbing them; monitoring data can be accessed both by the patient and the doctor, at the end it means that one just goes to the doctor when it is necessary, and that the doctor has much more data available in case that it is needed.
The last thing I would like to do in case of a long-term illness is to go periodically to the doctor if I can prevent it by some kind of remote diagnosis.
Quite often I am in this situation. What is funny is that even when a very special custom melody rings, the entire bus/metro/whatever within the range checks their mobile phone, just in case...
I don't really think that phone lines will die. One of the most expensive things is to run lines to all the houses, and phone lines are already there, telcos should try to use them.
Well, the article has a point: finding the right webpage is difficult, but it has been since all this ever started and is not something particular to Internet.
The most difficult thing on the internet, to my belief, is to find the very specialized article that you are looking for. The problem is that it may not even exist. Finding the same very specialized article in a huge library full of journals is even more complicated. So what? Next article.
Well, I wouldn't say absolutely nothing has happened after 1968. Look around and you will see thousands of artificial satellites orbiting the earth; since the MIR and now with the International Space Station there is a permanent pressence of humankind on the space; exploration trips to Mars, Cassini on its way to Saturn, landing on an asteroid with NEAR, spaceships to the sun and many, many other missions or accomplishments directly related to rocket and space science. The only thing that has not gone further is men landing on planets and the fact is that it may be fun, specially for the astronaut, but the gain over non-tripulated trips is slight.
I agree on the ICANN part, they are moving slowly and badly in this domain thing, but we don't want tens of different, not compatible domain systems, do we?
At least if it was a free (like in free beer) movement, maybe I could give it a try. But it is not, they want money to register my www.cool.travel address.
BTW: microsoft.* is already taken.
Nothing, we don't get nothing. Your wallet is stolen and you can report to police, your credit card and personal data is stolen and you don't even know, even if the ones that were keeping the info knew that it was stolen.
All this is very flawed.
MY data belongs to me, I claim the right to have it myself and just me, I don't want to be stored anywhere.
If I show you my car you don't assume it is yours know, why the heck should retailerwhatever.com feel the right to keep my data in a database just because I showed them for the purpose of buying once in a lifetime? Don't store my data anywhere and if someone breaks in your computers, I don't give a damn thing them, it is your problem. But no... it has to be the other way, store my data, a criminal breaks in, takes it, I am stolen, you never tell me and now it is YOU that don't give a damn, after all it is me that has been stolen. Sorry for the rant.
This is a problem, OS vendors care for security (I suppose) but the thing is that until now a bad security in an OS doesn't hurt the company: sales are the same wether a big vulnerability is discovered or not. But also not OS companies have little or no respect for security; sure they have all their "important" papers protected inside lockers, and have security personnel on the company headquarters and security checks, bad they have not that kind of vigilance when it comes to computers and Internet, they don't give importance to that, otherwise how is it possible that most of the attacks are known vulnerabilities. The point of full disclosure is that everybody should know so everybody can prevent but if a company doesn't bother... We the customers of this companies should have ways to enforce them to take security measures or we should know who can we trust and who we cannot, I don't know how but there should be a way. To put it short, bad security in a flight company puts them out of bussiness; but security in the internet world leaves things the same.
I find this jamming quite unacceptable.
I want my telephone, I need my telephone and I have it ALWAYS ON unless I need to do some maintenance, just like a Linux box, you know.
And despite beeing always on, it has never ringed on a movie theater, nor in a classroom nor in a restaurant; I have some education and in some places I have it in silent mode, if the call is important, I answer if I can or move to a place where I can talk freely without annoying people, if not, the call gets registered and I callback later. And I now that there's more people doing like me, don't harm us because of some miseducated; at the end, if they cannot use the phone on the classroom they will talk out loud to other classmates annoying you at the same level with different methods.
that's it.
If your open source screws up everything badly you have no one to blame. If your MS/ORACLE/WHATEVER does the same, at least you can yell at them on the phone.
What if I don't want them to browse my files?
Are they hacking in my computer if I don't give them express permission to look?
What if they make a mistake and my "this is a pretty woman speaking.mp3" is a recording of my girlfriend and they ban my access to Napster without ground? Can I sue them? Is this legal?
For those of you who don't know what is the meaning of 20/20 vision, it works this way:
20/20 means that you are able to see at 20 feet of distance what a normal person can see at 20 feet, then you have a normal vision.
20/10 means that you see at 20 feet what a normal person sees at 10 feet.
20/100 means that you need to be as close as 20 feet to see what normal people see at 100 feet. Well, you get how it works, I hope.
I had never heard of this kind of measurements where I live and I wear glasses so I suppose it will help some of you to understand better the meaning of the article.
I am very pessimistic about Napster, it will disappear as it is now.
Even if the offer is accepted by the record companies, which might be possible, I don't see how Napster is going to take money from their users.
This is not about good people sharing music for freedom, this is about people getting music for free (like in free beer) and this means that we don't want to pay a subscription for that.
Ok, maybe I would pay a subscription for that if it was really low enough, but then I want my music, which I have paid for, to be free like free software, I don't want copy protection on MY music; unacceptable to record companies views. I think that the music companies are getting it all wrong, they have already lost, they are not going to be able to control the artists any more, they are not going to be able to charge ridiculous prices for CDs that cost some cents in production, the music bussiness is going to change and there will be two winners: musicians and music listeners. Unfortunatelly for them the record companies will be the big losers. I see a future where musicians will base their careers mainly on playing music live and will use recorded music as a sort of publicity.
Let's face it, Napster is dead. Now let's find a good alternative.
