You just assume that the five joules are distributed evenly. That is not the case.
If the laser has a beam diameter of 0.5 cm, which is quite a lot for a laser at that distance the distribution looks quite different.
0.25cm^2 * PI * 0.1 cm is about a volume of 0.02 cm^3. The laser will not penetrate more than 0.1 cm of tissue in that short amount of time.
If we take the density of water we get roughly 0.00002kg and a temperature increase of about 50 K which should give you a nice burned spot on your chest.
With continously firing 10MW you could make jigsaw puzzles out of tanks.;-)
Only if the application is doing time consuming stuff in at least two threads. You say any modern GUI app, so is Firefox rendering a page multithreaded? What about my DVD Player Software, Games, TeX, Maple?
Dual cores processors seem to me like a pretty good alternative to a dual processor system. You don't have the hassle of 2 huge coolers blowing out hot air, the mainboards are don't have to be overpriced and it is already supported by all OS.
Some years ago I was thinking about getting a dual processor system. Alone the motherboard was two times as expensive as a similar single processor one, applications did not support it all and so on. I hope newer applications are ready for dual cores. Quake III was the first game I know that used two processors and finally I can consider that animated desktop background.
Is there a list which applications can effectively use dual cores besides obvious things like webservers?
Hmm, just think over your own definition of a terrorist a bit longer.
A lot of terrorists declared war on the United States for quite some time. Following your definition they would not be terrorists any more.
If you say that they must be "hunted down to the last man" than you are forcing them to fight to the teeth and cause as much damage as possible. This sounds like a pretty bad tactic to protected the American people.
"...yet _none_ of them release any concrete benchmarks."
Just try the gentoo homepage and there is the link: gentoo benchmarks
"What is the point in running the very first release of KDE?"
KDE 3.2.2 is more or less just a bugfix release that came out on the 19. April, it was still marked as unstable for x86 last week when I updated my system.
"Yet they forget that a company like Red Hat has about 5 or 6 of the _top_ kernel developers working..."
And surely they do not publish there code under the GPL so that other distributions can use it too. Gentoo could definitely be a lot more polished, but unfounded rants don't help.
So you have to pay about 20 pence per minute. I usually get two ads per week from NTL for cable. They offer here in Coventry a 1000 kbit/s line for about 30 pounds per month.
Enjoying a team game has nothing to do with you IQ.
If all the other guys are treating you badly than you should either join another team and ask yourself if you might be responsible for their behaviour too. Social interactions are often as hard to master as chess, both need training and reflection.
In my university the majority of the really smart ones that can do derivations on the blackboard, which remind you of Feinman, are working together in larger groups to discuss their research problems and to have fun, some even play soccer.
I feel sorry for you that you can't enjoy teams at all.
In the end you are jugding about people only because of their IQ. Such easy one-criteria-fits-all arguments are often used by people, who don't have the ability to think clearly and honestly.
Linux with KDE or Gnome has a similar usability than Windows, so that should not be the main issue.
Besides the home-grown VB applications the people actually working with the new system fear changes.
If Linux would emulate each and every button of Windows, they would still say: "Aber mein alter Bildschirmschoner geht nicht!" (But my old screensaver does not work!)
It seems that about 800 people are using the compromised keys.
To check if your key is in danger you have to check the type of the key. All type 20 keys can be compromised. Here is a small shell script to check our key:
Gateway was long know as the company completely focused on the mainstream with Windows/Intel, so these are very cool news for SuSE.
Everywhere on the Gateway pages there is still written:"Gateway recommends Microsoft(R) Windows(R) XP", but maybe things change a bit. Unfortunately if you have a look at the category "Operating Systems" on their website you can still only choose between
hi, at first I was very excited that the source code of my favorite online game was finally gpl'ed. Now the several problems and incompatibilities can be adressed. The remaining problem is cheating. I read several thoughts in this discussion about checksumms, cryptography, etc. but in my opinion nothing like this will work. To prove this I'll give you an example of a typical clan match in team fortress (a quake mod). 20 people join the server. Their maps are checked with a crc32 checksum (maybe md5, dont remember exactly), their models too. The movement protocol is a bit encrypted too. Then we perform a f_modified check. f_modified is the keyword for qizmo, a qw proxy, to calculate the checksum of the executable, the models, maps, sounds, etc and replies it to the server so that everyone knows that there is nobody cheating. This system with qizmo is quite safe and trusted by the online community. Now with the source release several problems come to the surface. The f_modified check still works, it reports incorrect binaries sucessfully. The problem now is the server. My clan is called "CORE", so it's a five minute hack to implement a function in the server executable like: if (teamname = "CORE") then give health 150% This cheat is not detectable for the other players and clan matches are useless now. Everyone here discusses about trust and encryption. With the gpl'ed quake we can not trust the clients and the servers! In my opinion this problem is almost unsolvable. Maybe we need a closed source program like qizmo for the serverside too, any suggestions? Vario

Science is not only about explaining things. Often predicting things is more important. For a prediction you need a theory. Then you test the theory.
The experiment goes like this:
1000 patients get the pill with something in it.
Another 1000 get the pill with nothing in it.
The results differ. Possible explanation and basis for a prediction: this medicine has an influence.
If you could make a prediction involving demons, that would be great. You could predict what we should do to please the demons and what not.
Have you done that? No? Then read some introductions to the philosophy of science.

To check if your key is in danger you have to check the type of the key. All type 20 keys can be compromised. Here is a small shell script to check our key:
gpg --list-keys --with-colon | awk -F: '($4 == "20") {print $0;}
If your key is in danger you should create a new one and revoke the old one immediately.
