Aren't there infinitely many "polynomial times" that are complete disasters?
Isn't n^1000000000000000000 polynomial time?
There are, but if you take n large enough, eventualy, for example 2^n will be larger then your n^'very_large_number'. So there is a significant difference between P and NP complexity. BTW no-one has yet proved that NP problems like SAT or the traveling salesman problem, or any problem derivable from those cannot be solved in polynomial time. It's just a very fascinating subject;))
Obviously, there's a much simpler solution to the telemarketing plague. Just build your own little cabin out there in the bush and move there. Forget you own a house with phone, fax and email. People lived like that 2000 years ago, and i haven't seen any history book on those days, in which people are know to complain about telemarketers:)
I was talking about powersaving, not perpetual motion. I'm aware of the fact that you cannot unplug the machine, and it will keep working. However, you might be able to use the heat to reduce the amount of needed 'extern' power.
If these chips also work in reverse, so they can make electricity out of heat, wouldn't it then be possible to use the heat from the CPU to generate electricity to power the CPU. OK, still additional power will be needed, but it looks like a win-win situation to me - cool your CPU and save some power!
This could have a huge impact on amateur radio! People can now start their own station just by putting their CRT-monitor on the roof and stream their mp3's on it!
I think the RIAA would not be happy whith that:)
But seriously, a friend of me actually managed to play.midi files on is CRT and receive this with an AM-radio in the same room. I found it pretty cool:)
and Microsoft has already created a version of Windows for interactive television boxes that has removable functions
Hey, not only for television boxes. My windows-pc has removeable functions allready! Let the machine running for >1 day, and i can't access any function anymore!
How? I need to put this thing somewhere. The desk seems the best place for the wireless monitor, since it has to stand steady, so what's the advantage. Doesn't seem very useful in an office environment to me.
Of course this is very easy to say, since you don't live there. In fact, you're just very lucky to be born in the western world, and not in the 3rd world. That kid in Africa that is starving to death, cannot be blamed for any situation in the 3rd world, he's just the victim. Poverty may be caused by any of the factors you named, but none of these factors can be blamed on him.
As wilde73 mentioned the western world is even taking advantage of this situation, kids there have to work (fabricate the products like your clothing) to keep their families alive. So you can't just say it's their damn problem, that's damn hypocritical!

A dicision is based partially on all things you've seen, heared and experienced in the past, but also by my 'free will' or creativity or whatever you like to call it.
If you believe all those 'decisions' are fully determined by the past, then you believe in a fully deterministic world, in which everything has already been planned, in every detail; for every atom in the universe it is determined where it will go, what speed, when it will fall apart, for all time.
There are people how believe in this deterministic reality, but I really don't.

Travelling into the future is no big deal
Actually it is, unless you believe in a fully deterministic universe. At every moment, i make decissions, and thus determine a little bit of the near future, would i decide differently, a different 'time-path' will be followed, and future will be different. And this is only me, there are millions of people who make decissions, and that's just people, there are millions of animals, plants, bacteria, that in a way 'choose' between different options, even atoms, of which is not determined when they fall apart, i could go on for hours here:).
There is no way one can predict the future timepath, so there is no way to timetravel to the future.
The main problem of OSS like linux for companies, I think, is that either it isn't up to date or it's not stable (enough). The latest stable linux release (potato) is really old compared to, say, win XP (i'm not saying this one is stable, but at least a lot of people THINK it is). If you want to make linux make better use of your cutting-edge-of-technology-hardware, you'll have to use the unstable release (or at the very least the testing release). I can imagine a company doesn't like to use software that is labeled 'unstable'. In the end I think it's a matter of who do you trust more, some people who programmed an OS in their spare time, or Bill Gates. Hard decision when lot's of money relay on that software...
Hey thanks. I've been looking for some good internetradio stations. I used to listen to www.garageband.com. I don't think they had to pay for the music, but the musicians offered the music. Unfortunately they've gone down some time ago (i believe because of a short of funds).
I'm not sure i 'understand' black hole 'theory'. If a black hole is a star that collapses into a singularity (or mathematical point), is than so that this star keeps collapsing indefinetely long (since, in theory, it can never reach the size of a mathematic point, since a point has no size. Am i right at this? Can someone explain?

I always wanted to know more about that cute cartoon dog of Micky Mouse. You know, about it's birth and growth and stuff. And about his belt too!

Don't see the scientific aspect, though
On the other hand, most people that own these older games, will also own a console to play them on ;)
Geez,
