Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Artificial islands could help China anchor its claim to waters that host some of the world's busiest shipping lanes. The South China Sea may hold as much as 11 billion barrels of oil and 190 trillion cubic feet of natural gas, according to a 2013 report by the U.S. Energy Information Administration. China has considered the Spratlys—which it calls Nansha—part of its territory since the 1940s and on occasion has used its military might to enforce its claim. In 1988 a Chinese naval attack at Johnson South Reef, in the northern portion of the archipelago, killed 64 Vietnamese border guards.
Director of regulated industry Harvey Bradshaw of the U.K. tells the Guardian: "This sentence is a landmark ruling because it's the first time anyone has been sent to prison for illegal waste exports." But five separate university research projects question what the crime was, and whether prohibition in trade is really the best way to reduce the percentage of bad product (less than 100% waste). Admittedly, I have been following this case from the beginning and interviewed both Benson and the Basel Secretariat Executive Director, and am shocked that the U.K. judge went ahead with the sentencing following the publication of the E-Waste Assessment Study last year. But what do Slashdotters think about the campaign to arrest African geeks who pay 10 times the value of scrap for used products replaced in rich nations?
Commercial drone flights are set to become a widespread reality in the United States, starting next year, under a 2012 law passed by Congress. Drone flights by law enforcement agencies and the military, which already occur on a limited basis, are projected to surge. The documents obtained by The Post detail scores of previously unreported crashes involving remotely controlled aircraft, challenging the federal government’s assurances that drones will be able to fly safely over populated areas and in the same airspace as passenger planes."
He says, "If a sequence of conventional mathematical operations isn't patentable, then no software should enjoy patent protection. For example, the 'data compression' patents that Justice Kennedy wants to preserve simply claim formulas for converting information from one digital format to another. If that's not a mathematical algorithm, nothing is. This is the fundamental confusion at the heart of America's software patent jurisprudence: many judges seem to believe that mathematical algorithms shouldn't be patented but that certain kinds of software should be patentable. ... If a patent claims a mathematical formula simple enough for a judge to understand how it works, she is likely to recognize that the patent claims a mathematical formula and invalidate it. But if the formula is too complex for her to understand, then she concludes that it's something more than a mathematical algorithm and uphold it."
The first stage is to orbit a cubesat, a tiny, coffee can sized satellite that would contain two highly accurate accelerometers that would go into orbit around Europa and measure its gravity field. In this way the location of Europa's subsurface oceans would be mapped. Indeed it is possible that the probe might find an opening through the ice crust to the ocean, warmed it is thought by tidal forces.
The second stage is to deploy even smaller probes called chipsats, tiny devices that contain sensors, a microchip, and an antenna. Hundreds of these probes, the size of human fingernails, would float down on Europa's atmosphere to be scattered about its surface. While some might be lost, enough will land over a wide enough area to do an extensive chemical analysis of the surface of Europa, which would then be transmitted to the cubesat mothership and then beamed to Earth.
