* This new GOP plan to steal the presidency really is something else. Kudos.

* Priscilla Wald on Contagion.

* “These are songs about growing up on a tough planet,” said Springsteen, telling reporters that when the idea of humans and aliens working side by side in an extraterrestrial labor colony first occurred to him, he immediately knew he “had to tell their story.” “The Martians aren’t trying to run away from their lives or make excuses. They’re proud of what they do and where they’re from, even if the high-impact ion-compression carbonate mining industry isn’t what it used to be.” The Onion previews the next Springsteen album, Red Dust. Via io9.

* Koomey’s law: the electrical efficiency of computation has doubled roughly every year and a half.

Imagine you’ve got a shiny computer that is identical to a Macbook Air, except that it has the energy efficiency of a machine from 20 years ago. That computer would use so much power that you’d get a mere 2.5 seconds of battery life out of the Air’s 50 watt-hour battery instead of the seven hours that the Air actually gets.

* Asked and answered: How much of the Internet is actually for porn?

* And Kevin Drum’s chart of the day crows that “Obamacare is already working.”

Truly, the results are staggering.
