Comment Re:35 years of computer time (Score 1) 309

How about measuring that in actual computer usage? X MHz on Y cores per Z nodes over A hours? Or at least say it would have taken one X MHz processor 35 years to compute it.

Um, they did. From the article:

it would take a good desktop PC (Intel Nehalem, four-core, 2.8GHz) 1.1 billion seconds, or about 35 CPU years, to perform this calculation

VASIMR Ion Engine Could Cut Mars Trip To 39 Days 356

An anonymous reader writes "It would take about 39 days to reach Mars, compared to six months by conventional rocket power. 'This engine is in fact going to be tested on the International Space Station, launched about 2013,' astronaut Chris Hadfield said. The Variable Specific Impulse Magnetoplasma Rocket (VASIMR®) system encompasses three linked magnetic cells. The 'Plasma Source' cell involves the main injection of neutral gas (typically hydrogen, or other light gases) to be turned into plasma and the ionization subsystem. The 'RF Booster' cell acts as an amplifier to further energize the plasma to the desired temperature using electromagnetic waves. The 'Magnetic Nozzle' cell converts the energy of the plasma into directed motion and ultimately useful thrust."

Submission + - Google: Apple VP Rejected Google Voice iPhone App (blogspot.com) 1

bruckie writes: "Today Google released the full, unredacted letter that they sent last month in response to an FCC inquiry into the roles of Apple, Google, and AT&T in the reported rejection of Google Voice from the iPhone App Store. In contrast to Apple's statement that it "has not rejected the Google Voice application, and continues to study it", the previously-redacted section of Google's letter states that in a phone call in July, "Mr. Schiller [Apple SVP of marketing] informed Mr. Eustace [Google VP of engineering] that Apple was rejecting the Google Voice application"."

Submission + - Our Moon May Hold Coldest Location in the Milky Wa (nytimes.com)

tromtone writes: ""The shadowy craters near the south pole of the Moon may be the coldest places in the solar system, colder than even Pluto, NASA scientists reported Thursday as they unveiled some of the first findings from the Lunar Reconnaissance Orbiter spacecraft.In the newly released data, thermal measurements showed that daytime temperatures over much of the surface reached 220 degrees Fahrenheit â" hotter than boiling water â" before plummeting to frigidness at night.But the bottoms of the craters, which lie in permanent darkness, never warm above minus 400.""

Comment Re:Auto Pilot (Score 1) 203

Heck with the way things are now, the Auto Pilot can nearly land a plane by itself.

Actually, autopilot can land a plane without any human help, and in some cases it's even required to. I was talking to a pilot for United (friend's uncle) a couple years ago, and he said that in high winds or poor visibility, airline regulations prevent the pilot from landing the plan manually. The pilot is required to allow the autopilot to land the plane. Pretty crazy stuff.

Comment Carriers get paid for incoming calls (Score 5, Informative) 383

An interesting, relatively unknown fact that I picked up while working on telephony systems a while back: carriers get paid (by other carriers) for incoming calls.

Not only do you pay more to your carrier to listen to the inane voicemail prompt (since you might use more minutes), but your carrier also pays more to your friend's carrier. For example, if I'm an AT&T customer and I call a Verizon customer to leave a voicemail, AT&T has to pay Verizon for every second that I'm on the phone. This (perverse) incentive makes more sense than charging people for more minutes, since often the company charging for minutes (AT&T in this case) is not the company that controls the recorded message (Verizon).

Comment Not the first time (Score 2, Informative) 495

This sounds a lot like the 40-year-old Carterfone decision, where AT&T argued that allowing people to connect third-party devices to their network could disrupt or degrade service. I'm pretty sure that modems and Panasonic phones didn't ruin the telephone system, and I have a feeling that jailbroken iPhones wouldn't be the end of the world, either.

Comment DRM? Really? (Score 1) 403

It sounds to me like the EFF is overreacting again. When the new iPod shuffle came out, the they sounded the alarm about headphones requiring "DRM authentication". They later retracted their statement. Turns out that the "DRM" was just an electrical signaling protocol that allowed the headphones to send button press events to the iPod. You knowâ"the kind that any EE would design. The headphones and the iPod have to communicate somehow.

It sounds to me like this is more of the same. From the article:

car manufacturers now severely limit the number of repair shops that are allowed to have the tools, diagnostic codes and updated repair information essential to being able to repair late-model cars

A lack of information, or the need for sophisticated test equipment does not automatically imply DRM.

I'm all for making information on car diagnostic protocols and diagnostic code semantics more freely available, but let's call it what it really is.
