No, because I don't want to carry a key around everywhere, and because I don't want to (and sometimes can't) install encryption software on every computer I need to use email on.

For me, the extra privacy isn't worth the extra inconvenience.

US Air Force Pays SETI To Check Kepler-22b For Alien Life 301

New submitter iComp writes with this quote from El Reg: "The Search for Extra Terrestrial Intelligence (SETI) has announced that it is back in business checking out the new [potentially] habitable exoplanets recently discovered by NASA's Kepler space telescope to see if they might be home to alien civilizations. The cash needed to restart SETI's efforts has come in part from the U.S. Air Force Space Command, who are interested in using the organization's detection instruments for 'space situational awareness'."

Nice conspiracy theory.

The Australian standard voltage is 230V +10% -6%. So 255V is outside the allowable range. If they deliberately set the supply to 255V, they'd be exposing themselves to a huge lawsuit. Any 250V-rated components or insulation that failed, causing damage or fire or injury, would all be their fault.

Also, by setting the voltage that high, the power used by other loads (some types of lights and motors, and various other things) would increase noticeably. Generating that much extra power would be more expensive than paying the tiny number of people who have solar feed-in systems.

tl;dr: if you're getting 255V, it's a technical problem rather than a conspiracy, and you should be complaining to your electricity provider rather than to random slashdot readers.

Copyright Isn't Working, Says EU Technology Chief Neelie Kroes 314

superglaze writes "Against the backdrop of governments and courts around the world ordering ISPs to block file-sharing sites, European commissioner Neelie Kroes has said people have started to see copyright as 'a tool to punish and withhold, not a tool to recognise and reward. ... Citizens increasingly hear the word copyright and hate what is behind it,' the EU's digital chief said, adding that the copyright system also wasn't rewarding the vast majority of artists."

> Secondly, the requests and responses are travelling through the Internet and of course through the airwaves, which means someone could easily alter those replies with the aforementioned valid keys (pretty easy)

If an attacker can arbitrarily alter the contents of an SSL session, we're all a bit screwed anyway. It's certainly not "pretty easy".

Robotics

Startup Testing Mobile Farmbots 243

An anonymous reader writes "Wired reports on Harvest Automation, a Massachusetts company developing small robots that can perform basic agricultural labor. The ones currently being tested in greenhouses and plant nurseries are 'knee-high, wheeled machines.' 'Each robot has a gripper for grasping pots, a deck for carrying pots, and an array of sensors to keep track of where it is and what's around it. Teams of robots zip around nursery fields, single-mindedly spacing and grouping plants. Key to making the robots flexible and cost-effective is designing them to work only with information provided by their sensors. They don't construct a global map of their environment, and they don't use GPS. The robots have sensors that detect boundary markers, a laser range finder to detect objects in front of them, and a gyroscope for navigating by dead reckoning. The robots determine how far they've traveled by keeping track of wheel rotations.'"

I disagree that the carbon tax "bones the economy on a grand scale". I also disagree that we "fucked the future of the country".

Could you provide any information (e.g studies predicting a significant decrease in GDP, standard of living or any other reasonable measure of progress) to support this claim?

I agree that the carbon tax in Australia won't make much of a difference. But of course we can look at each individual in the world and say their individual actions won't make much of a difference. It would be unreasonable to use this as a reason to take no action.

Comment Re:Impossible to prove true randomness exists. (Score 1) 189

It's impossible to prove anything at all, aside from abstract mathematics and "I think therefore I am" and such. But we shouldn't let philosophy and arguments about human conventions get in the way of the fact that Occam's Razor and the acceptance of unprovable theories is actually incredibly useful.
