Desert Farming Experiment Yields Good Initial Results 178

Taco Cowboy writes "For the past year or so, a tiny scale farming experiment in has been carried out in the desert field of Qatar, using only sunlight and seawater. From the article: 'A pilot plant built by the Sahara Forest Project (SFP) produced 75 kilograms of vegetables per square meter in three crops annually (or 25 kilograms per square meter, per crop)' If the yield level can be maintained, a farm of the size of 60 hectares would be enough to supply the nation of Qatar with all the cucumbers, tomatoes, peppers, and egglants that it needs. 'The project will proceed to the next stage with an expansion to 20 hectares, to test its viability into commercial operation.'"

Slashdot Asks: What Are You Doing For Hallowe'en? 273

Hallowe'en is my favorite holiday: I like seeing costumes (and walking around in my own), and seeing what people do to decorate their houses, yards, etc. For the second year in a row though, I've failed to come up with a really good scheme for making my own place appropriately spooky. So, in hopes of loosing some inspiration for myself and others, I ask today what you're doing to spookify your surroundings (or your person) tomorrow, especially if it means using technology in interesting ways. Sensor-activated scary sounds or lights? An Arduino or Raspberry Pi-controlled costume? Elaborate trap-door? Infrasonic hackle-raising subwoofer install? Maybe one year Alek Komarnitsky will switch to Hallowe'en instead of Christmas, and offer a webcam-equipped remote-controllable haunt.

CAPTCHA Busted? Company Claims To Have Broken Protection System 141

sciencehabit writes "A software company called Vicarious claims to have created a computer algorithm that can solve CAPTCHA with greater than 90% accuracy. If true, the advance would represent a major breakthrough in artificial intelligence. It would also mean that the internet will have to start looking for a new security system. The problem, however, is that Vicarious has provided little evidence for its claims, though some well-known scientists are behind the work."

France Moves To Protect Independent Booksellers From Amazon 264

Hugh Pickens DOT Com writes "Tourists often marvel at the number of rich and varied bookstores along Paris streets. Right across from Notre Dame Cathedral is one of the city's most famous independent bookstores, Shakespeare and Company. Inside, every inch of space is crammed with books and readers. The city buys buildings in high-rent districts and tries to keep a core of 300 independent bookstore by offering booksellers leases at an affordable price. 'We have to keep our identity,' says Lynn Cohen-Solal, 'because if we don't, all the shops are exactly the same in Paris, in London, in New York, in New Delhi, everywhere.' Now Eleanor Beardsley reports at NPR that the French government has accused Amazon of trying to push the price of physical books too low and is limiting discounts on books to ensure the survival of its independent booksellers. France's lower house of parliament has unanimously voted to add an amendment to a law from 1981, known in France as the Lang Law which sets the value of new books at fixed prices and only allows retailers to lower books' set price by 5%, in an effort to regulate competition between booksellers and to promote reading. Guillaume Husson, spokesman for the SLF book retailers' union, says Amazon's practice of bundling a 5 percent discount with free delivery amounted to selling books at a loss, which was impossible for traditional book sellers of any size. 'Today, the competition is unfair,' says Husson. 'No other book retailer, whether a small or large book or even a chain, can allow itself to lose that much money,' referring to Amazon's alleged losses on free delivery. Amazon spent $2.8 billion on free shipping worldwide last year to gain a competitive advantage. The bill limiting Amazon's price reductions in France still has to pass the Senate to become law. In a statement, Amazon said any effort to raise the price of books diminishes the cultural choices of French consumers and penalizes both Internet users and small publishers who rely on Internet sales."

We go through this every time there is a DARPA challenge:

5 Intellectual Property
DARPA claims no rights to software developed by Open Track competitors as a result of participation in the CGC. DARPA does not intend to disclose the CQE and CFE Technical Papers outside the Government, with the following exception: CGC Technical Papers may be handled by DARPA support contractors for administrative purposes and/or to assist with technical evaluation. All DARPA support contractors performing this role are bound by nondisclosure agreements. DARPA does not intend to disclose CGC Technical Papers to contractors to duplicate, commercialize, or for reprocurement or reverse engineering purposes.

Do you think all the participants of the past DARPA grand challenges relating to autonomous vehicles have given away their IP? Of course not. Those teams that pushed through have made lucrative deals with car manufacturers and others.

All DARPA want's to do is spur innovation. A challenge like this is essentially a heads up that in 5 years they'd like to spend a lot of money on procuring services like these. In the past, they'd just give someone the money to build it, and maybe it worked, maybe it didn't. At least now it's a bit more market driven.

Also, i'm not sure if anyone else picked up on this, but he was giving out his box.com account credentials to clients so they could upload straight to the folder.

I gave them the email addresses of several people with whom I had shared files over the years, thinking maybe the account had been mistakenly assigned to them.

Hrrmm? that's odd. Why would you even think because you sent someone a link to your cloud shared folder that the cloud company would magically given them the account...unless you didn't send them some link....

My lovely and talented wife, with whom I collaborate on stories for Family Circle (where we used Box.com a lot), had apparently invited an employee of this PR firm to upload an image to one of our shared folders last April

Ahh, now this language seems a bit too obtuse. "Invited an employee to upload an image". At first glance, you'd think you send this PR employee a link and they uploaded to your box.com folder. But you can't do that with box.com.... Only way to let someone upload to your folder is via an E-mail ( which won't work for large files ) or the 'upload widget' which you have to host on a website and it's up to you to lock it down ( he didn't use this either ). Failing that, YOU HAVE TO GIVE YOUR ACCOUNT USERNAME/PW TO THE PERSON TO UPLOAD TO YOU.

They probably pulled all the accounts used from an IP range known to be the PR firm, and assumed that's "PR Firms" employees. Since this employee had the username/pw, what else were they to assume.

Not a brilliant move on Box.com's part, but also, a stupid move on this writers part.

Most of these large cloud storage apps make it difficult for someone else to 'contribute' (upload) files. Otherwise they get abused for warez or porn.

Long story short, this guy violated their terms of agreement and gave away his username and password and was amazed when his files disappeared.

If he wasn't a tech writer, they would have written him off and rightly so. If anything, this is "Treat me different, I'm the press" mentality.

Not all are locked. It wasn't illegal to switch cars on the subway until 2005. And then it became a 75 dollar fine.

The ones that are locked are the newer models which the locks can be controlled by the conductor. Also, only the trains that have extreme turns or spots where there is a very large gap between the cars, get locked.

The 1/2/3 line weren't locked last time I hit a car with no AC in the summer.

Also, on the 1 line for south ferry you have to move between cars because only the first 5 reach the platform... Not sure how they handle this these days.

That's one way to look at it.

The other way to look at it is, the USGIS name database should have been contracted and paid for in say 10 year increments. Any funding disruption less than a full year should not impact them...

Plenty of other departments of the government are running just fine off user fees too. Not sure if USGIS required a fee to use, but why not ask for 10 bucks a year to cover their data hosting costs.
