Ya know, your numbers are probly better than anything I coulda cooked up lol. It's just every time I see these blurbs about shattering previous pre-order records or product x eclipsing its predecessor's release, I wonder if these numbers are even valid. Simply trying to remain safely skeptical.

So far my biggest criticism of the new iphone, sight unseen, is their claims of battery life. While I understand there have been immense improvements in mobile battery life in the past year, the numbers Apple is claiming seem a bit lofty. They barely upped the battery capacity (1432 mAh? someting like that, all I know is its their most capacious battery yet, even if by only a minute margin) but they're claiming 8 hours of web browsing on 3G and LTE? My current book learning (studying Electrical Engineering) and current experience with an LTE equipped smartphone tells me those numbers most likely shouldn't be the same. Factor in the bigger screen which will have a higher power draw, and a faster processor, and these numbers just aren't adding up for me. I really want to see some battery tests.

So I'm not trying to incite a flame war, but I'm honestly curious to see who is coming from what in the pre-order figures. By which I mean, how many are current iphone users looking to have their latest and greatest, who's switching from one ecosystem to another, how many are first time smartphone buyer, etc.

I've always wondered how these "millions of pre-orders" figures broke down.

Submission + - US President intending to implement CISPA by executive order (techdirt.com)

An anonymous reader writes: A draft of a new executive order is circulating among insiders that will attempt to implement CISPA without congressional approval. Jason Miller of Federal News Radio claims to have seen it and according to him, it contains most of the provisions of the Lieberman/Collins Cybersecurity Act that failed in the U.S. Senate. The provisions appear to put pressure on companies to "share" information with the government.

Submission + - SPAM: How to Charge a laptop battery effective

ltpower writes: Claims of fast charging laptop battery in one hour or less usually results in lower charge levels. Such a charger simply eliminates stage two and goes directly into 'ready' once the voltage threshold is reached at the end of stage one. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.

Depending on the charger and the self discharge of the laptop battery, a topping charge may be implemented once every 500 hours or 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05 volts per cell and turns off when it reaches 4.20V/cell.

No trickle charge is applied because the laptop batteries for laptop is unable to absorb overcharge. Trickle charge could cause plating of metallic lithium, a condition that makes the cell unstable. Instead, a brief topping charge is applied to compensate for the small amount of self-discharge the laptop battery and its protective circuit consume.

Submission + - Flash spotted on Jupiter: Is it a hit? (nbcnews.com)

puddingebola writes: From the article, "Astronomers are abuzz over sightings of a flash on Jupiter — which suggests that the giant planet has taken another bullet for the solar system team. Monday's report follows Jovian impacts in 2009 and 2010. As in those earlier cases, the call has gone out to look for any visible scars on Jupiter's cloud tops. That would be a sure sign that an asteroid or comet was drawn in by the planet's gravitational pull, potentially saving us from a cosmic collision threat."

Submission + - 58% of South Australia's Power Generated by Wind Farms (reneweconomy.com.au)

SA_Democrat writes: You've probably heard people saying that wind energy doesn't work, well, South Australia would beg to differ. Ongoing investment in wind farms has resulted in wind providing 58% of demand . Australia has a National electricity grid, so excess energy is exported to other states. Of course, in a country this size, the wind is always blowing somewhere.

Submission + - Is Windows Phone 8 Already in Trouble? (slashdot.org)

Nerval's Lobster writes: "In the days following Nokia unveiling the Lumia 920 and 820 at a high-profile event in New York City, various publications have begun questioning whether Windows Phone 8’s rollout will be smooth as silk or rougher than a rocky patch of country road. The Verge, following up on its report that Nokia had faked some of the footage promoting the new Lumia devices’ cameras, tried to give Microsoft a minor aneurism with a Sept. 11 story questioning whether Windows Phone 8 would launch on schedule; it alluded to “delays and bugs” in testing.

Ars Technica, meanwhile, threw its own darts with a Sept. 6 story highlighting the total lack of information about Windows Phone 8’s release date.

Compare that to Amazon’s rollout of the Kindle Fire HD, which has a definite release date and pricing, or Apple’s iPhone 5, which—at least if history is any indication—will also make its debut with a price-tag and shelf date in place. As these IT giants head into the crucial holiday shopping season, Microsoft’s information vacuum could end up confusing consumers to the point where they turn to rival vendors for satisfaction."


Submission + - Windows Store opens to developers worldwide (msdn.com)

An anonymous reader writes: A year ago this week at //build/, Microsoft unveiled the largest developer opportunity ever coming with Windows 8 and Windows Store. You may also recall that at Windows 8 RTM last month, Microsoft opened the Windows Store for any qualifying business. Starting today, the Store is officially open for all individual developers in 120 markets around the world to register and submit their apps. This marks the last significant milestone for the Windows Store before Windows 8 becomes generally available on October 26, and signifies the moment where all individual developers across the world can access the Store in preparation for the biggest developer opportunity ever.

Submission + - Steve Mann Is Fighting for Your Cyborg Rights (vice.com) 1

pigrabbitbear writes: "Last month, Dr. Steve Mann, a professor at the University of Toronto who has been living as a cyborg for his entire adult life, was attacked by employees at a Parisian McDonald’s.

He’d gone into the restaurant to use the bathroom — McDonald’s in France tend to have single-occupancy, “cyborg friendly,” bathrooms — and grab some food with his family. The management, however, objected to his head-mounted camera glasses, a system called “EyeTap” that captures images at 120 frames per second in 1080 × 1920-pixel resolution. Even after they had been shown a doctor’s note explaining the device and the impossibility of removing it without special surgical tools, the McDonald’s employees allegedly roughhoused Dr. Mann, ripped up his note, and kicked him out of the restaurant onto the street. After Dr. Mann made his story public online, McDonald’s corporate responded with an assurance that nothing of the sort had happened.

Then he released the images. Taken with the very glasses his aggressors objected to, the pictures show the perpetrators in flagranti, surrounding the cyborg at eye-level and swiping at his head."


Submission + - NASA:Dry ice snow lands on Mars – no word on school closings (networkworld.com)

coondoggie writes: "NASA said today new data show carbon dioxide-based snow, or what's more commonly known as dry ice, falls on the Red Planet's south pole -the only known such weather in our solar system.
Frozen carbon dioxide requires temperatures of about minus 193 degrees Fahrenheit (minus 125 Celsius) and the new analysis is based on data from observations in the south polar region during southern Mars winter in 2006-2007, identifying a tall carbon dioxide cloud about 300 miles (500 kilometers) in diameter persisting over the pole and smaller, shorter-lived, lower-altitude carbon dioxide ice clouds at latitudes from 70 to 80 degrees south."


Submission + - Amateur Astronomers Spot Jovian Blast

RocketAcademy writes: Spaceweather.com reports an explosion on Jupiter, which was detected by two amateur astronomers.

According to Spaceweather.com, the event occurred at 11:35 Universal Time on September 10. Dan Peterson of Racine, Wisconsin, observing through a 12-inch Meade telescope, observed a white flash lasting for 1.5-2 seconds. George Hall of Dallas, Texas was capturing a video of Jupiter at the time, which also captured the event.

It's believed that the explosion was due to a comet or small asteroid collision. Similar events were observed in the past, in June and August 2010.
