True, and someday every IO process will probably be handled by a dedicated processor. A distributed operating system will run processes on each, making it easy to reprogram the tasks. Fast interconnects will make a NUMA architecture possible.
Currently however that future is far off. It's simply much cheaper to centralize processing, so the bus will remain an issue for some time to come. For most situations this will be fine, for specialized situations where a single (fast) real time process is needed, or when IO is more important than CPU power...it sucks.
(listening to my integrated audio which takes about 7% of my processor, and I don't care a bit)
No, they (Intel processors) do run at full speed. However, with hyperthreading both virtual processors use the same infrastructure. Since they can both run processor threads at the same time, that infrastructure is used more efficiently though, so you get (slightly) better performance. Say up to 10/20 percent or so.
Obviously, with dual cores you get a 100% upgrade at the same clockspeed. It depends on the intercommunication between the processor threads if your system will indeed perform twice as fast. If you could run folding at home on each CPU, then they would get twice the results, since that application does not need a fast path from one processor to another.
That is the problem with seperate caches. Multiple processor threads of the same application probably wont perform that well on these designs. The communication between both processors is hampered, and they will probably have to fill both L1 caches with the same data to run the same process. They will probably use a higher level cache to make up for that though.
ps. just my basic knowledge of processor design guys, feel free to shoot as many holes in this story as you can.
I'm not so sure. By taking away the reasons to switch from operating system (for most people this is the apps, not the os) you might end up with people putting up with Windows instead.
I mean, I ran the Gimp on my operating system some time ago, and with cygwin a lot of unix utilities run fine. Even worse, there is a steady stream of Open Source packages coming out for Windows nowadays.
For linux on the other hand, there are little or no commercial applications available in the entertainment sector of it. I think this this situation is better for MS than for anybody else.
All insdustry watchers, maybe except Toms Hardware, saw the EE as a trick to get the performance crown from AMD again. At (literally) any price. I don't know if it sold; you must really want to have the ultimate performance at any price to buy one.
Now that they've released faster processors that are up to par on performance with AMD (and removed the GHz speeds from the processor names) there is no need for the extreme edition any more. So now they don't have to sell server chips to make up for bad performance on the PC front.
SmartCard readers are always called SmartCard readers, even if they can write as well. Actually, they can just send commands, it is up to the IC what to do with the command, read or write.

Not really. P2P just means Point 2 Point. Which does exactly mean that you are talking straight to the computer you want to download wares from, or indeed the person that you want to talk to. The lookup part does and the configuration part are not specifically P2P, but they are clearly the most difficult to get right.
It uses the fastest connection available. It only routes the calls themselves though other computers if there is no other way. If both sides are behind a NAT firewall it uses a UDP protocol. Both computers get a call request through the network (using a server or easy reachable pc) and send an UDP package to each other. One of these packages will probably be dropped by the firewall, but after that the stateless UDP protocol is accepted at both sides, and high quality/high encryption calls can be made, using the shortest route available. The trick is to use a side channel to let the systems know the IP and port number of the caller/callee in advance. For this it uses the skype network.
Nope, you are not misinformed. According to a Dutch television documentary the programmers did not want that to happen. A collegue, who handled the commercial part more or less, sold the program to an Australian company, without them knowing. Basically they were conned out of their business. After that the ads came in.
This out the top of my head, since I don't have the documentary lying around. It was shown to me at the Copy=Right? festival of my ISP, XS4ALL (.nl).
Yup, that was my idea too. Make a nice raid-5 disk storage somewhere (s-ata + command tagging would do nicely thank you) and connect the computers too it. Your data is more safe, the irritating hard drive is somewhere else. Do one install for all your computers on it using the old boot from network option and there you go.
Unfortunately my fans are making way more noise than my hard drives together though, so you might want to use special computer for this as well.
So then we are counting on all those developers just doing stabalization, and no new features? Somehow that's an even more disturbing point. Why not create a 2.7 playground? Obviously the harm here is that the developers would play more than doing stabalizing work, but now they could be poluting the current tree with the new stuff.
They have added "new technology"? What about? Storing IPv6 in DNS records? I thought that was already available. Not from ICANN mind you. We'll put it down to scrappy journalism. The reporter probably would not know an IP address if he stepped on it. Um.
When is/. going to get IPv6 and xhtml/css2? I wonder.

That is not really the case in Europe. Sure you could read the license plate, but you still can't get to the personal data unless you are in the law enforcement business. I understood that in several US states this information is public. In the Netherlands just the land-owners are publicly listed as far as I know.
IP is international, so you will have to thread very carefully by saying that (little) privacy is lost. Processor ID's were not accepted by the general public either.
Anyone else who thought he was speaking about a Water Closet (better known as toilet) instead of storing them? I thought it was rather obvious that they would not put a camera in there. That would be _really_ 1984.
That is all, and that's the whole point. Now they can track anybody for no reason at all, since technology (well, the use of the technology) alows it. When will they start putting image recognition on these camera's because they are ineffective? And when are [fill in ethnic group] going to be wrongly ID'ed as thief, or "terorist"?
Nope, that's not likely to happen. Most likely there will be a few people that control the robots and live prosperous, while the other 95% is dying because of malnutrition (no job, no money etc).
It does scare me a bit I must admit. I can think of a lot of jobs in our company that are already within reach of this robots capabilities...
Since Bush has been in power the Geneva convention is more or less void, a country has been overrun (ok, with a wrong leadership), the country is spending billions (more) on weapons, Israel gets a "do whatever you like" card, rights have been taken away from citizens, corporate america has been placed above the law, the VN was almost invalidated, money for good causes is being withdrawn and you think it is _getting_ ridiculous?

Try the metric system. It's much easier to use. Especially if you want to measure how much a liter of water weights in kilo(gram)s.
The filter at home does just the opposite thing. I pour water through it and I get coffee. Weird indeed.
