RedEaredSlider writes: Relativity is usually something said to affect only things moving at speeds close to that of light. But now calculations show that the common car battery works because of relativistic effects.
The work was done by a team from Sweden's Uppsala University and the University of Helsinki. They looked at how much energy a lead-acid battery produces if one doesn't take into account relativistic effects. Then they did the same set of calculations including them.
What they found was that a large portion — some 80 percent — of the 2.1 volts a battery produces was from relativistic effects.

The IETF invites all interested parties to participate in the technical evolution and work toward even greater stability of the Internet.”

Judge Susan Ilston, in the U.S. District Court for the Northern District of California, said Sony has to show that George Hotz, a hacker who posted a method of "jailbreaking" PS3 consoles, has some connection to California if Sony is to claim damages for his work on the PS3.

DesScorp writes "AccuWeather meteorologist Joe Bastardi has a challenge for climate scientists. He wants one or more of their rank to accept a bet about temperature trends in the coming decade. Bastardi is making specific predictions. 'The scientific approach is: you see the other argument, you put forward predictions about where things are going to go, and you test them,' he says. 'That is what I have done. I have said the earth will cool .1 to .2 Celsius in the next ten years, according to objective satellite data.' Bastardi's challenge to his critics — who are legion — is to make their own predictions. And then wait. Climate science, he adds, 'is just a big weather forecast.' Bastardi's challenge is reminiscent of the famous Simon-Ehrlich Wager, where the two men made specific predictions about resource scarcity in the '80s."

However, this one is about a bug in the Google Apps services that actually lets you make free voice calls to the US from some other country. (India in our case)

When the PS3 launched in 2006, estimates pegged the price of producing the consoles to be as much as $250 more than the price at which they were sold. Production costs have dropped since then, but there have been several price cuts as well. Now, almost four years later, Sony Worldwide Studios president Shuhei Yoshida says they're finally turning a profit on the hardware.
"This year is the first time that we are able to cover the cost of the PlayStation 3,' Yoshida said. 'We aren't making huge money from hardware, but we aren't bleeding like we used to.' In May, Sony began shipping new PlayStation 3 consoles with smaller and more cost-effective graphics chips. Now, Yoshida said, Sony is looking at replenishing retail stock that has been running on empty since January rather than cutting the price. 'When we bring the cost of hardware down, we are looking at opportunities to adjust prices if we believe that will increase demand,' he explained. 'At the moment, we are trying to catch up our production.'"

It's got Ethernet, and a certain amount of nerd appeal. Read more here. There's even a small text adventure. Feedback, abuse and offers of cash all welcome (to varying degrees).
AGreenberg writes: I've written a post at Forbes' cybersecurity and privacy blog on a study by the Ponemon Institute showing that Americans' trust in government privacy protections is at an all-time low. That's largely because Americans' privacy trust in the Census Bureau fell dramatically over the last year, more even than trust in the NSA fell after the revelations of its warrantless surveillance of American citizens. This is a sad consequence of paranoia fueled by bizarre and ridiculous reports like this one, which argued that the Census would use GPS to target missiles at citizens' homes.

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

AndrewDBarker writes "Modern Warfare 2 will use a matchmaking setup powered by IWNet for online play (as we've discussed). It's too early to say what Rage will use, but Carmack indicated he believed the servers are something of a remnant of the early days of PC gaming. That said, he realizes the affinity many PC gamers have for them — and is glad Rage won't be leading the charge away from them. 'The great thing is we won't have to be a pioneer on that,' he says. 'We'll see how it works out for everyone else.'"
