I agree with you on the tribalism issue. And I agree that Obama has not lived up to many of his promises. However, you're not living in reality if you think nothing good has changed. Take a look at PolitiFact's Obama promise meter - certainly he hasn't kept his promises, but (a) he's not a dictator and (b) I think its fine if he gets to office and finds things are different than they looked before he got there, due to secret intelligence, etc.: http://www.politifact.com/truth-o-meter/promises/obameter/

Comment Re:How do we generate the power? (Score 0) 525

This is a summary of an article showing that DC transmission of electric power is cost effective up to about 7000km (4300 mi). It's rather old, but I don't think anything has changed in terms of physics. Also superconducting power lines have started being installed, which was not the case when this article was written: http://www.geni.org/globalenergy/library/technical-articles/transmission/cigre/present-limits-of-very-long-distance-transmission-systems/index.shtml Regarding the climate change, I think that is debatable. The amount of incoming energy is the same whether or not PV panels are present or not. More may be reflected from white sand than a dark panel, but a lot of the heat the PV panels generate is reradiated upwards. And you also have to factor in the reduction in CO2 output the PV panels give you vs gasoline engines, coal, etc.

I don't know about you but my clutch is where my left foot is. Touching the clutch is part of driving the vehicle over here. Press clutch to disengage gearbox. Everyone who drives a manual over here knows that.

That's actually the clutch pedal, not the clutch itself, hence the remark about the resident pedant above yours.

I think MMR is the only common childhood vaccine that might contain egg proteins, and very few children with egg allergies actually turned out to be allergic to MMR. In any case, children can be tested for an allergic reaction to the vaccine before the vaccine is given.

I agree the Android market is poor right now, but I can see it improving over time as the apps get better.

I totally agree with your comment about "dual core" being a useless feature. I used an iPad for quite a while before getting an iPad 2, and while logically I know the iPad 2 has a dual core processor and more memory, the only improvement I've really noticed is that the iPad 2 is noticeably lighter and easier to move around.

Submission + - Phony TCP Retransmissions Can Hide Secret Messages 2

Hugh Pickens writes: "New Scientist reports that a team of steganographers at the Institute of Telecommunications in Warsaw, Poland have figured out how to send hidden messages using the internet's transmission control protocol (TCP) using a method that might help people in totalitarian regimes avoid censorship. Web, file transfer, email and peer-to-peer networks all use TCP, which ensures that data packets are received securely by making the sender wait until the receiver returns a "got it" message. If no such acknowledgement arrives (on average 1 in 1000 packets gets lost or corrupted), the sender's computer sends the packet again in a system known as TCP's retransmission mechanism. The new steganographic system, dubbed retransmission steganography (RSTEG), relies on the sender and receiver using software that deliberately asks for retransmission even when email data packets are received successfully. "The receiver intentionally signals that a loss has occurred," says Wojciech Mazurczyk. "The sender then retransmits the packet but with some secret data inserted in it." Could a careful eavesdropper spot that RSTEG is being used because the first sent packet is different from the one containing the secret message? As long as the system is not over-used, apparently not, because if a packet is corrupted the original packet and the retransmitted one will differ from each other anyway, masking the use of RSTEG."

Submission + - Flaw made public in OpenSSH encryption (zdnet.com) 1

alimo20 writes: "Researchers at the Royal Holloway, University of London have discovered a flaw in Version 4.7 of OpenSSH on Debian/GNU Linux. According to ISG lead professor Kenny Patterson, an attacker has a 2^{-18} (that is, one in 262,144) chance of success. Patterson tells that this is more significant than past discoveries because "This is a design flaw in OpenSSH. The other vulnerabilities have been more about coding errors"

The vulnerability is possible by a man-in-the-middle intercepting blocks of encrypted material as it passes. The attacker then re-transmits the data back to the server and counts the number of bytes before the server to throws error messages and disconnects the attacker. Using this information, the attacker can work backwards to figure out the first 4 bytes of data before encryption. "The attack relies on flaws in the RFC (Request for Comments) internet standards that define SSH, said Patterson"

"Patterson said that he did not believe this flaw had been exploited in the wild, and that to deduce a message of appreciable length could take days.""

World's First Battery Fueled By Air 205

Hugh Pickens writes "The Telegraph reports on the revolutionary 'STAIR' (St Andrews Air) battery could now pave the way for a new generation of electric cars, laptops and mobile phones. The cells are charged in a traditional way but as power is used an open mesh section of battery draws in oxygen from the surrounding air that reacts with a porous carbon component inside the battery, which creates more energy and helps to continually 'charge' the cell as it is being discharged. The battery has a greater storage capacity than other similar-sized cells and can emit power up to 10 times longer. 'The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery,' says Professor Peter Bruce of the Chemistry Department at the University of St Andrews. 'Our target is to get a five to ten fold increase in storage capacity, which is beyond the horizon of current lithium batteries.'"
