    The breath, sweat and urine will all evaporate the water back into the air.

    Do soldiers go around urinating outdoors? I expect much of it will go into either:

    Septic tanks where it will take hundreds of years to sink into the water-table before eventually being pumped back up by humans.

    OR

    Sewers, where it will be wisked away to some distant river, lake, ocean, and still be removed from the LOCAL environment.

    Evaporation is adding water to the atmosphere. Condensation is removing it.

    the urbanization of the desert has actually added to the relative humidity via increased plants and the watering of them.

    I don't know about you, but I don't generally go around urinating on the ground. Usually it's flushed and either put underground where it can't escape for hundreds of years, or travels off to some distance river, lake, or ocean.

    You might think that 300 gallons a day is a lot of water, but keep in mind that the atmosphere contains 1.12E17 gallons of it, and that only represents 0.0031% of the water on earth.

    That is a ridiculously small number. For the US army in Iraq, you're probably talking about 10s of millions of gallons per day.

    but keep in mind that the atmosphere contains 1.12E17 gallons of it

    Most of which is in places with excess moisture (like over the oceans, lakes, tundra, etc), rather than evenly distributed around the globe. The deserts have far less than their fair share of this moisture.

    And removing perhaps just 5% of the moisture in an area could have a dramatic impact, as the higher pressure could cause stronger winds. Though, since much of this water will be sweated right back out to the atmosphere, I have no idea what kind of an impact to really expect.

  9. Very specific instructions... on Could I Run a TV Station on Linux? · · Score: 1

    To get a perfect interlaced signal out of a computer...

    Setup Slackware 10.0 (1) on a fast machine, with a recent NVidia card (2)... Install the NVidia binary driver.

    Configure X.org to use a 60Hz refresh. IF you are going to need S-Video out, use a resolution of 800x600 and set "Overscan" (in xorg.conf) to a large value, around 0.8 should work.

    Get mplayer working with -vo gl. Add -dr for performance. Try different yuv= parameters to gl. Try with -vf bgr24. Once OpenGL output that works, add -vf tfields,softskip (3) which will give you (absolutly great quality) interlaced video output which will rival any professional setup. Hopefully that video stream will be accepted properly by whatever your broadcast hardware is. (I'm not an analog TV broadcast guy, so I have no idea what you may have)

    Also add "echo 1024 > /proc/sys/dev/rtc/max-user-freq" to your rc.local, so MPlayer can use rtc for accurate timing. You probably want to used the "-fixed-vo" option as well.

    That should get you started, and the hardest part taken care of.

    After that, it's largely left as an exersize to the reader...

    bmovl (or the bmovl2 patch) should allow you to display any arbitrary on-screen graphic overlays you want.

    You can write a very simple command-line program to control MPlayer via slave mode... As long as your program can keep a schedule, tell MPlayer the filename of the videos you want it to play, etc. you're all set.

    If you're a real low-budget operation, you might even use MPlayer on a second machine to scan the video (before you broadcast it) for black frames. Then, you could use that info to have your scheduling program automatically insert your commercials where the feature's scene-changes occur.

    And last but not least, you'll certainly want X11 running without any window manager, and probably an all-black background, to hide any minor mistakes that occur.

    (1) I know Slack 10.0 will work perfectly (except for the NTP daemon) for your task. 10.2 has some X11 bugs.

    (2) NVidia's binary driver is absolutely essential for proper OpenGL video output, so no ATI cards allowed.

    (3) If -vf bgr24 is necessary for your NVidia card, the filter line is going to be tricky: "format=yv12,tfields,softskip,scale,format=bgr24"

    I don't want to stand out in the sun all day, day after day picking fruit. Even if picking fruit all day payed better than IT does, I think I would find something else to do.

    Good for you. I'm rather sure 80+% of the population disagrees, however. Myself included.

    I would much rather let someone who wants to do the work come to this country and continue to have them do it.

    Mexicans don't want to do the work any more than Americans do. They do it because it's the only option they have, considering their illegal status. Make them legal, and they will go to other jobs that pay more, or demand higher wages for their work, just like every other American.

    Indentured servitude isn't a good policy, even if it's necessary to make US-grown pears profitable...

    People pay a lot more per pound for Alaskan Crab than they do for pears. If the pears start costing what the crab costs, I think they will eat more crab.

    It doesn't matter who eats what. Crab fishing is the hardest, most dangerous job in the world, yet it's all Americans that do it, not illegal immigrants... Because the pay is high enough to live on, unlike what farmers currently pay.

    With pears being produced in other countries at lower prices, the farmers here will not be able to pass on price increases in order to pay higher wages. In the California Farm Bureau article I linked to in the GP, the farmer was talking about other pear farmers in the area buldozing their orchards.

    Good for them. It's plain and simple economics.

    If your business model depends on slave labor to be profitable, you don't import slaves, you change the business model.

    Some farms are a marginal business with a lot of risk.
    Other farms make good money.

    Subsudising the "marginal" farms with illegally-cheap labor, is not a smart move on any account. In a capitalist society, those companies NEED to go out of business, to make way for stronger competitors that can pay decent wages.

    Maybe next year WalMart will have a shortage because all their workers left to go pick pears for more money. ;)

    I can only hope... That could only possibly raise the standard of living for the working-poor in this country.

    Where we once exported lots of food abroad, maybe we can buy more food from countries that don't have our labor laws.

    Funny you'd say that, since your solution to this problem is to sweep aside our labor laws, and allow indentured Mexicans to work for less-than minimum wage.

    Hell, maybe it would suddenly be profitable to have farms IN MEXICO, where the Mexicans have rights, aren't afraid of being exported if they complain, etc.

    California grows a lot of food and it is wierd to see it sitting on the ground rotting.

    Employers have historically pulled LOTS of dirty tricks in the past, to try and get better deals on labor. It wouldn't suprise me if they are doing it again. After all, more expensive employees are far better than no employees at all.

    At worst, if I was a farmer, I'd probably put up a sign along the lines of "Pick your own pears $5" and make some money, if not as much as usual. That's how capitalism works, when the situation changes, you change your business model the best you can. In the long term, MANY businesses profit far more, when they are finally forced to come to terms with changes, and think up new business models for their industry.
  11. Morning Shows... on The Daily Show as Substantive as Broadcast News · · Score: 1

    News viewership is terribly sad. It seems the worse the source, the more people watch it.

    Evening News is taking it's cues from the morning shows. More in-depth coverage of "How did being kidnapped make you feel?" and people crying on camera, filling the time, and little to no time for substantive news from politics, war, economics, and general world news. School shootings are terrible, but spending half an hour every day for weeks, interviewing scared kids and parents, isn't helping anybody.

    Evening News is bad, but local news is MUCH WORSE... If you think back to days before the invasion of Iraq, all of the major nightly news programs had a nice run-down of all of Bush's evidence, and why it was all utterly incorrect. The local news programs, however, just showed Bush's original sound bytes on the subject, and never followed up when new information came along. The viewership of local news is why some 70% of people (or whatever the figure) believed there were links between Bin Laden and Iraq.

    The thing most people have forgotten, though, is that you are NOT stuck with just those crappy options. The alternate national newscasts are actually a lot better...

    Both CBS and ABC have very good (fast-paced) morning newscasts at 4:30-5:00 am that are packed with news from the entire day, vastly unlike evening news programs, which are half commercials, crawl along at a snail's pace, and barely get through the three top stories of the day... Of note especially on /. they also have more of a tech slant than other news programs, reporting on the major developments, before you see it here on /.

    If that isn't to your liking though, you also have the option of ABC's WNN around 2-4am every night. Over the course of an hour, they get just slightly more in-depth than the half-hour CBS/ABC morning news shows, and throw in lots of idle time, uncomfortable anchor chit-chat, and regular bits of fluff news pieces if you like a little of that.

    Despite the opinion around here that news is crap and utterly worthless, I easily see some 98% of the news stories I care about in a half-hour a day, as opposed to spending a couple hours over a day, reading the same stuff through Google News or the like. So, IMHO, set your DVR for 4:30, and the news not only won't suck, but it will be quite useful.

    Republicans want to legalize the practice of companies exploiting foreigners (guest worker program), while the Democrats want the xenophobic voters to be less worried about losing their jobs to foreigners.

    As for "jobs Americans don't want to do..."
