In the article "Comparison of Water Consumption between. Greenhouse and Outdoor Cultivation"
http://www.itc.nl/library/papers_2006/msc/wrem/mpusia.pdf

we can see that greenhouses save some 50% of water compared to outdoor cultivation (on page 11).

That mean we can 'readily' half the agricultural water consumption. Imagine greenhouses the size of Nebraska...

R is an excellent language to learn for just about every field. It's ability to import and export data to MS based resources such as Access, Excel, MS-SQL and other non-MS sources makes it a versital tool. It's commerical parent is S-PLUS and is nearly syntax identical with minor variations. Buy the book, use the tool, impress your Eve Online players by pinning down the July Tritanium prices and hitting the weekly averages within .5 ISK by doing time series analysis using regression plus ARIMA on the residuals. Find out cool things like Hulkageddon impacts frigate prices more then exhumers and MORE! FUN FOR THE WHOLE FAMILY (Except your big sister because she's icky and into boys....) For those what want to do google searches but find 'R' difficult there is the rseek.org site and a few quick links to get you started while you wait for the nutshell book to arrive in the mail.

Oh yee ignorant /.ers...

Here's a beginner's introduction to 'soils', i.e. dirt, of which there are actually many, many types:

Oh, heck, there's even soil taxonomy, for pete's sake (for those of you who are truly twisted enough to find out more):
http://www.itc.nl/~rossiter/research/rsrch_ss_class.html

In other words, there ain't no such thing as just plain 'dirt!'...:-)

Enjoy, and have another closer look at that dirt that's all around you, and what it may (or may not) contain...

Personally, I'm very excited to learn more about the undoubtably unique characteristics of Martian dir...er, I mean, soil.
I wonder how it compares to various Earth and Lunar soils, etc.?

Map of China's Coal Fires

Coal fires produce about 2-3% of the total world carbon dioxide production due to fossil fuels.

Some of Chinese coal fires have been dated to the Pleistocene Era!

As to China, nobody mentioned the underground continuous coal fires (I got that from here a month or two back).

this link works

you are exactly right

but, not to take away from any of your statements at all, there is a gigantic underground coal fire in china that emits enough CO2 in one year to equal and surpass all exhaust from all cars in the US.

and that's just the coal fire burning coal, not counting all of the industrial development in china. it's no wonder things must be insane over there.

here's the first site i could find with info, there are better:

i had to repost, my first post was to the wrong place.. woops.

And don't forget China's coal fires!

WTF? Your being paranoid. Noone accused USA of being the fault of this.

If we want to find a source for the blame, China should be first on the list. China has let numerous coal fires burn out of control, becoming the number one source for carbon dioxide emissions into the atmosphere.

According to experts, 2% to 3% of CO2 emissions originate from this single source. Check this map out to see how widespread the problem is - literally all of northern China has fires raging uncontrolled and disregarded by the Chinese government. So what if the USA has more storms that kill its citizens - in fact, this is a good thing for China.

If only the Deep Atlantic Conveyer Belt would shut down so the colonialist European pigs would freeze to death. Then China would be the world's only superpower. Serves them right for all their meddling!!!

From http://www.itc.nl/~bakker/info/rs-data/cd-family.h tml:

The ISO 9660 standard is a specification for PC's and has two levels. Level one looks like the DOS filing system. File names consist of eight characters a dot and an extension of three characters. The only characters allowed are the alphanumeric and the underscore. Directories, contrary to DOS, can have no extensions. All alphabetics are in UPPER case; some software maps this to lower case. Either the file name or the extension may be empty, but not both ("F." and ".E" are both legal file names).

...

For Unix there is the "Rock Ridge" extension of the ISO 9660. The Rock Ridge extensions use some undefined fields in the ISO-9660 standard to allow full unix-like filenames, symbolic links, and deep directories. "Rock Ridge" is named after the town in the movie "Blazing Saddles" for no particular reason.

IANAPL, but this would seem to be prior art if it appeared when I think it did (ca. 1994). I'm pretty sure the first couple Linux CD collections I got in early '95 had Rock Ridge extensions.
