But it takes power to compress nitrogen; i.e., power roughly equal to the heat it gives off.
But they recover this heat, and use it to power a steam turbine at the liquid nitrogen producing plant, which means that it is far more efficent than a regular air conditioner, where all the heat is pumped away into the air. I seem to remember a figure of 75% of the energy used in the compression is recoverd from the heat.
I'm confused by this comment. Are you saying underage drinking is worse than spray painting sidewalks? Or that painting a sidewalk is more than 30 times worse (assuming 8 hour days?) than underage drinking. Those proportions sound about right to me. Drinking (unless it is excessive, or it is followed by driving a vehicle etc.) does no harm to other people, and little harm to oneself. Painting a sidewalk costs a lot of money to clean up, and while it isn't cleaned can be an eyesore to many thousands of people.
As an aside, here in the UK, it's very rare to find anyone who hasn't been to a bar and had a drink before they were the legal age (18 - not 21). In fact, I don't think I know anyone other than myself who actually waited.
OT Note to US Gun fans: The UKs increase in crime over the last 2 years is probably about 60-80% due to excessive drinking (by under and over aged people), and about 0% due to handguns being banned, unless you include owning a handgun now being a crime, in which case it's about 0.5% due to handguns being banned. The rest is due to cuts in Police numbers, and an increase in mobile phones being stolen by kids (aged 10-16) to keep up with the fashion of other kids at school.
The whole point in local time is that different parts of the earth face the same part of the sky at different times (mainly that they all face the sun at mid-day). Therefore, the meteor shower will always be directly above at 2am.
I still don't believe that the concept of slim computing with Netscape (or other browsers) & Java and no windows is a ridiculous one. I believe it could well have been on a good footing, catching up with Microsoft, and may even have overtaken them by now.
They should have joined in, ported Office to Java, and slimmed windows to be just a Java engine with it's own look and feel. Sun did not help in this respect by holding on to the Java standards. Microsoft would have a reduced market share, but with MSN and hardware etc. as well as Office still a significant one. There would be more competition from Apple, Acorn, Sun, IBM, and many others in diversity of hardware, and more competition in software.
I don't belive these concepts are ridiculous. I believe they were possible. The only thing that makes them look silly is Microsoft's success at FUD.
I do think that open source has benefited indirectly from Microsoft's behavior. I know I wouldn't be as interested in it (coming from and Acorn / RiscOS background) had Microsoft been any good.
The situation is complicated by the fact that Netscape also behaved badly, and predatorially with their browser. The trouble is, they saw Microsoft's reaction coming, and tried their best to prepare for it. They underestimated the near infinite power of that company.
I am worried that if Microsoft comes out of this, they will produce much better software (Windows 2000 is actually quite good - honest!), and rapidly become far too powerful - if they are not stopped now, there is a danger that they will become more powerful than any government, assuming they have not reached that stage already. Ironically, China, with it's pro linux stance, may end up saving the free world. (I think I may have gone a bit past the point here - I'll stop).
One final thing, has anyone seen IE for MAC? Why do you think it so much better than IE for Windows?
Err, in BBC BASIC, 1982, you can do something like:
PROCstring("Hello World","print")
END
DEF PROCstring(a$,b$)
IF b$="print" THEN
REM ========== Print method ==========
PRINT a$
ENDPROC
ENDIF
REM put all the other methods for strings here
PROCwhateverstringsareinheritedfrom(a$,b$)
ENDPROC
It's kind of object oriented. It might require BBC BASIC 5 (1987) or something, though. I'm sure somebody will say it's not proper OO, but I think I can extend it a bit if neccesary.

I am only guessing here, though!
