Crippling drought this year has caused more than $1 billion in damage. As it has played out, anyone affected by the drought or trying to manage it has turned to a once obscure map that has become key to understanding what's happening: the U.S. Drought Monitor. From a report: That includes water planners who decide resource allotments. Farmers who need water for their livelihood. Federal bureaucrats who use the map to calculate aid for the Livestock Forage Disaster Program. And then there are citizen scientists like Dave Kitts outside of Sante Fe, N.M. "I think it's a little obsessive, but I check it every Thursday," says Kitts, who has lived on the same 2-acre spread in New Mexico for decades. Dry years like this past one can crust the soil and kill his pinyon trees. "It's just upsetting and depressing to me," he says. "And when it moves the other direction, it definitely lifts my spirits."

Scientist Mark Svoboda started the drought map 20 years ago, when Congress took an interest after drought struck Washington, D.C. He directs the National Drought Mitigation Center at the University of Nebraska, Lincoln. "We're covering everything," he says, "from groundwater, stream flow, temperature." In bad drought years like this one, the map has patches of crayon yellow, orange and red that show the levels of drought. Right now, there's a deep crimson bull's-eye in the hardest-hit area of the southwest, where Colorado borders Utah, Arizona and New Mexico. The Drought Monitor map is updated weekly, often taking into account input from hundreds of people -- in addition to scientists. Ranchers and farmers from across the country also send missives to state and national offices, making the map a mix of art, science and farmer wisdom. But it starts with recommendations from state climatologists on any potential changes.

New submitter Chipmunk100 (3619141) writes "Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions."

elecngnr writes "Maybe size doesn't matter. ZDNet has a story about how the Mac mini may shift consumers away from the larger tower style desktops to smaller ones. Other computer makers, such as HP, have so far been unsuccessful in marketing small computers to consumers. However, Apple does have a history of leading the charge in paradigm shifts in certain aspects of consumer products (e.g. GUI's, color changes, the iPod, and the list goes on). It is also important to recognize that they have been wrong at times too (e.g. the Cube, the Newton, and the one button mouse). Time will tell which list the Mini will belong to."

Anonymous Meoward writes "Researchers at the University of Nebraska - Lincoln have come up with robotic traffic barrels ('bollards', for our British readers) that can be repositioned by remote control, thus minimizing a road worker's time in harm's way. Apparently, the barrels can be grouped and positioned by an autonomous 'shepherd' unit, that is also smart enough to also remove an errant barrel from its herd. The barrels themselves are about as intelligent as.. well, orange barrels. Okay, let's cue the more obvious jokes..." Reader zombieflesheater submitted this previous attempt to mobilize road furniture.

terradyn writes "Over at iPodlounge they've discovered that the iPod mini's have a major issue with their headphone jacks. It looks like the jacks connection to the main system board is extremely poorly engineered and so normal use will wear it out and cause lots of static after around 35-40 days... If any pressure on your iPod Mini results in crackling and static, you should return your iPod immediately to an Apple store for a free replacement. They're also theorizing over in the forums that the iPod Mini shortage may be a cover for this problem..." Update: 04/12 01:08 GMT by T : billybob writes "Someone in the forum thread originally linked to has posted pictures of the iPod taken apart, demonstrating the problem."

RanmaPlex asks: "I've been asked by a university professor to design a network security lab for use by about 15 students. Designing a course was asked earlier, but little info was discussed on equipment. It needs to be vendor independent if possible. I've got ideas on using virtual machines, patches, IDS, firewalls/vpn and sniffers but would like to know what the Slashdot community can come up with."

LiamRandall writes "Time magazine has an article discussing the effects that recent layoffs in corporate America has had on remaining workers. While I'm glad that I haven't been laid off (like 1/2 my group) I'm overloaded with all of my new responsibilities. On one hand I feel very fortunate to still have a job- I feel some what guilty complaining given that the computer industry is second in layoffs. While some former coworkers of mine got the axe because upper management didn't understand what their contributions to the company were, others were dead wood anyway. The Chinese symbol for crisis is danger + opportunity; in these turbulent times do you find yourself rising to the challenge or being overloaded with responsibility? Is your to-do list growing exponentially? What new work are you faced with and how are you dealing with it?"

Tetard asks: "Long live the pipe! Since the `|' was invented by Doug McIlroy in 1973, has there ever been a more effective way of reusing tools and connecting data ? The mouse is a device of the Beatles era; Rather than try and provoke nostalgia in the older ones among us, I'm asking myself, as are others: when we don't try to reinvent the wheel, or at least improve it, why must we try and copy it every time ? Xerox PARC exposed us to WIMPs and we haven't done better: some innovation, some plastic surgery -- but no "paradigm shift" -- where's the creative destruction that will take us further ? Graphical component programming is turning us into click-happy bonobos^H^H^Hchimpanzees, as we fail to find new ways to manage and connect richer data streams. My web designer friends are damaged for life because of mice, and yet we persist... Where do we go from here ? If we ever invent the graphical pipe, let if have keyboard shortcuts." Yes, you've probably seen a similar question to this run by Ask Slashdot before, but this time I'm wondering if maybe we need new input devices before the WIMP paradigm is replaced with something better. Might any of you have ideas on what form these input devices might take?

For those interested, here are the previous stories that have handled this type of question:

• GUI Research - Is it Still Being Done?
• Pipes In GUI's?
• Pipes in GUI's? (Redux)

So what it will take to break us out of the WIMP box (or prison, depending on your bias), maybe new input devices would do it, but quite frankly, I wouldn't be surprised if a 3D interface might be another route (it would possibly spark interest in designing a new input device that would work better with 3D interfaces, or maybe data-gloves could serve this purpose?). Going on a limb, maybe this guy might just be the ticket.

One can interpret it as waves of matter diffracted from "crystals" made of light, it's like matter and light swap roles. It was predicted in 1933 by a pair of future Nobel Prize winners, Russian Peter Kapitza (1894-1984) and Englishman P.A.M. Dirac (1902-84), but the technology needed to demonstrate it didn't exist at the time. It wasn't until April 11, 2001, when it was observed for the first time in Herman Batelaan's lab in the Behlen Laboratory for Physics at the University of Nebraska - Lincoln. This is the first time _ever_ that scientists have shown that light can bend matter, not just the opposite."

whatsit asks: "I was recently reminded of a little DOS database called Nutplus (also called Nutshell in its earlier versions) and decided to contact the company that owned it in hopes that they would open source it. After some research and some tears, I found that they may be out of business! I found a Web site address: www.fairsoft.com that doesn't work. The company's name is/was Fairhaven Software. I also came across an 800 number and a long distance number for them, but both ring busy. What happens to old software when the company that owns it goes out of business? How can I go about getting rights to the source code? Does anyone have experience with a similar situation? Do copyrights on these pieces of software ever expire?" Are there any ways to obtain the rights to software after the parent company is long gone (assuming the code happens to exist after the lifespan of said company)?

An an anonymous reader linked us to Quinn and Mark's LinuxWorld Page which among other things, features several pictures from the Cafe Babylon Slashdot party on monday, tons of pictures from the floor, and more. Definitely worth a read. I'm still hoping to have a chance to write a real report, but our booth seems to be a circus. I haven't even had enough time to wander around and collect my share of the free booty.

Miguel de Icaza has announced version 0.30 of the GNOME libraries ("Bouncing Bonobo"). The new libraries are much more stable and is the first release with CORBA support in the core. Other new features include the GNOME metadata library implementation, the GNORBA library (for mixing CORBA & GNOME), and much better documentation. Update: Miguel wrote in with a link where you can read about the bonobo.

Ryan Morgan wrote in to tell us that a new version of MindsEye- a 3d modeller for *nix was released this morning. There are binaries available if you want 'em. Check out their web site and their ftp site if you want to download them. I've never tried this program, but I may give it a whirl this weekend.
