Rude Drivers Reduce Traffic Jams 882

BuzzSkyline writes "Traffic jams are minimized if a significant fraction of drivers break the rules by doing things like passing on the wrong side or changing lanes too close to an intersection. The insight comes from a cellular automata study published this month in the journal Physical Review E. In effect, people who disregard the rules help to break up the groups that form as rule-followers clump together. The risk of jamming is lower if all people obey the rules than if they all disobey them, according to the analysis, but jamming risk is lowest when about 40 percent of people drive like jerks."

Comcast Intercepts and Redirects Port 53 Traffic 527

An anonymous reader writes "An interesting (and profane) writeup of one frustrated user's discovery that Comcast is actually intercepting DNS requests bound for non-Comcast DNS servers and redirecting them to their own servers. I had obviously heard of the DNS hijacking for nonexistent domains, but I had no idea they'd actually prevent people from directly contacting their own DNS servers." If true, this is a pretty serious escalation in the Net Neutrality wars. Someone using Comcast, please replicate the simple experiment spelled out in the article and confirm or deny the truth of it. Also, it would be useful if someone using Comcast ran the ICSI Netalyzr and posted the resulting permalink in the comments.

davidphogan74 writes "I wanted to drop my TV and phone. I don't use them, and don't want to pay $40/mo more for them. It took two calls to Comcast to drop those parts. The first call led to a message telling me to call back during business hours. The second call went to sales, and got me a $40/mo cheaper deal. No audio, sorry. I didn't plan ahead.

Why does it take this much work to drop service from a cable bill? Don't they get this is part of why I'm dropping services?"

The Universe As Hologram 532

Posted by kdawson
from the surface-projection dept.
Several readers sent in news of theoretical work bolstering the proposition that the universe may be a hologram. The story begins at the German experiment GEO600, a laser inteferometer looking for gravity waves. For years, researchers there have been locating and eliminating sources of interference and noise from the experiment (they have not yet seen a gravity wave). For months they have been puzzling over a source of noise they could not explain. Then Craig Hogan, a Fermilab physicist, approached them with a possible answer: that GEO600 may have stumbled upon a fundamental limit where space-time stops behaving like a smooth continuum and instead dissolves into "grains." The "holographic principle" suggests that the universe at small scales would be "blurry," its smallest features far larger than Planck scale, and possibly accessible to current technology such as the GEO600. The holographic principle, if borne out, could help distinguish among competing theories of quantum gravity, but "We think it's at least a year too early to get excited," the lead GEO600 scientist said.

Suggest you just sit there and wait till life gets easier.
