It is a closed system. A closed system per definition can exchange energy with the environment. A system which doesn't exchange energy with the environment is an isolated system. In practice there is possibly only one real isolated system, the universe, but isolated systems are useful in chemistry and physics as tools to simplify computational models.
Not sure if this should be very surprising behaviour. I used to read the UK version of PC Magazine, specifically for the featured columnists. Then I moved to the US for a while and picked up the US PC Magazine. It was a real eye opener. The UK version was much more confrontational and actually criticising the industry, vendors and crappy products. The US version was quite tame in comparison. Which maybe was why they close the UK version eventually, perhaps the ad flow dried up...

Sounds like eternety can be quite long even at the beginning.
SAP on the other hand bought Pilot Software, a California based company (with engineering in Cambridge, Mass.) for an undisclosed sum the other day. Pilot Software has many of the engineers from the original Pilot Software, which went through a number of transitions before ending up with SAP. They have some of the very first OLAP tools which still work really well, but have been concentrating on Performance Management tools over the last three or four years. Pilots PM tool, PilotWorks, is actually rather nice and it will be interesting to see how SAP uses them in the future. I used to work for the European Pilot distributor a couple of years ago.
To go beyond 1 million years you use sea bottom sediments and a number of different climate proxies. The oldest sea bottom sediments are about 170 million years old. You can still use oxygen isotopes in foraminiferes, but also relative plankton populations for example.
And vapourised silicate wouldn't explain ball lightning which has been seen inside aircraft which are flying. There may be more than one phenomena here as the descriptions vary quite a lot.
Is that Cingular or Jobs speaking through Jobs mouth? I for one would have loved to have a iPhone version of Delicious Library on my phone, not just a synced list on my iPod. I think this message will change over time, bullheaded Steve might be but not stupid.
The company coyly says that it does not plan to become American until half of all sales are made there and Americans hold half its stock (it reckons they now hold about a third of the company), but it may not have long to wait.
Well, the Economist actually argued for an asteroid warning system to be put in place as well at some point. Can't find the reference now though. But it had a big asteroid on the front page.:)
That's as may be, but the UK is much closer in attitude to the US than it is to continental Europe.
This is said quite often in the UK, but as a non-UK European who has lived nearly half my life in the UK and several years in the US I would argue that this is a misconception. I consider the British much closer to the Swedish or the Dutch, for example, than the US Americans in most social aspects I can think of. The structure of the legal system may be further away from continental European systems and foreign policy is closer to the US than many other European countries, but from my point of view there is more in common between the society in the UK and the Netherlands than there is between the US and the UK.
But then there are probably as many points of view of that as there are people.;)
The close button'll be on the tabs, but that seems about the only user-visible improvement.
I only use Safari and Firefox. Safari has the close button for a tab on the tab itself. Firefox has one close button for all tabs (it closes the current active tab).
I find that I make much fewer mistakes with Firefox when it comes to closing tabs. Often when I shift between tabs in Safari with the mouse I will close a tab by accident. This is increadibly annoying. And I do not think that having an "undo close tab" feature is the answer. A close button on each tab may be a useful feature from a beginners point of view, but when you use browsers a lot it just becomes annoying.
Now, the Iranian president (Mahmoud Ahmadinejad) is a crazy old man who participated in the holding of the hostages from the American embassy when he was younger, and is actively pursuing a nuclear weapon. If Pat Robertson did either of those things, he would be thrown in jail in two heartbeats.
Pat Robertson doesn't need to do either of these things. The US government doesn't need the help. Guantanamo is no better than the hostage holding in Iran and the US has comitted to removing nuclear weapons in the START treaties, and haven't done it. So Pat's efforts aren't needed.:b
Considerably more interesting OTEC news is that according to The Yomiuri Shimbun, the island of Okinotorishima will be subject to a joint reserach project by the National Fisheries University, an independent administrative agency and Saga University to assess whether the island is suitable for an OTEC installation. The project is supposed to start the 10 January 2006 and will involve about 20 people. The team will collect data about temperatures in different layers of water as deep as 1,000 meters, the quality of water, sea floor topography and currents. A report will be compiled by March. Japan is at odds with China over the establishment of exclusive economic zones (EEZ) around the atoll--which is about 11 kilometers in circumference--under the U.N. Convention of the Law of Sea.
The exhaust from combustion of hydrogen is water vapor. If this is a more serious greenhouse gas than originally thought, can hydrogen really be considered an eco-friendly fuel?
This is a general misconception, that hydrogen fuel cells will produce significantly more water vapor than fossile fuel cars already do. I found this explanation useful, from this web site (I have lost the exact page). Essentially it says (based on some assumptions) that a gasoline internal combustion engine vehicle puts out 0.14 kg water/mile and a hydrogen fuel cell vehichle 0.15 kg water/mile.
However, if you produce the hydrogen using an energy source which is polluting, then you haven't gained anything.
Kind of funny. I probably watch as many films in the cinema as I ever did. I spend a lot more time with the internet than before. What lost out? TV. Not even the news anymore...
You are behaving as if you belong to a network security guild. If I don't know everything about network security then I shouldn't be allowed to learn anything more about network security. Especially at Slashdot, the hotbed of network security guild members.
Clearly this is a very effective way to improve the security on the networks around the world... ah, pardon the pun, I mean the Job Security for our dear paid up members of the Network Security Guild.

Both India and China have restrictions on imports and ownership of companies. They have learned from history. There is, as far as I know, no industrialized country that didn't start out by protecting its internal markets, "copy" innovations from others and made sure that the home market was forced to by from the local industry, until the local industry was fit to compete with the surrounding world.
If China and India opened up their markets today and allowed the industrial west to export anything they could build to them and also buy any company they wanted to have, these two countries would soon be owned by the large corporations of the west and India and China would not be able to build up a R&D based industry like we have in the west.
The corporate world of the west and their political croonies are of course always complaining about this as it curbs their profits and limits their future expansion. But is it bad for the Indian and Chinese population? I don't think so. In the long run they will be better off having a strong corporate world owned by their billionairs, as those billionairs will co-exist much better with the political structure of those countries, which is bound to be better for the country and the people.

Or just some good old fashioned scutwork. Look it up and cross reference. ;)

This is nearly a dupe of another Slashdupe story which was up not so many days ago.
The only thing missing really are archives that last. The Waybackmachine just doesn't hack it.

Here is a link to a co-op that laid their own fibre. Quite informative.
There have been at least one good article on AskSlashdot before on this subject.
