RealSki Augmented Reality iPhone App Might Save A Few Black Diamond-Chancing Lives [IPhone Apps]
Gizmodo helm-man and keen snowman Brian nearly creamed his pants when he heard about RealSki's augmented reality iPhone app, and rightly so—the app uses the camera, accelerometer, compass and GPS to map ski-trails of over 80 US mountains.
You'll need to be running at least OS 3.1.2 on your iPhone 3GS to use RealSki, and to make it work you move the phone around you on the ski-trail, so it can map the location. Then, digital overlays will appear within the app, showing you where the lifts, lodges, restrooms and restaurants are, as well as trails (and their level of skill) and any other parks or features of that resort.
The free download will provide maps for five of the major resorts, but if you're going off-piste and need other maps, you can purchase additional ones (there's 80 available) from within the app. Here's hoping the RealSki app is intelligent enough to bolt you to the chair lift when you decide to conquer the difficult Black Diamond course.

Ski California getting increasingly difficult thanks to Nanny State regulations
California now officially a "No Fun Zone"
by Eric Dondero
Skiing, snowboarding, sledding, getting increasingly difficult at California's famous resorts? Blame it on the Nanny State, more specifically un-elected bureaucrats and the Democrat-controlled legislature. Authorities in California are getting increasingly safety conscience to the point of outright bans on those seeking a little Winter fun.
From Frank Girardot, Metro Editor for San Gabriel Valley News Group, Whittier Daily News, "Nanny state forces us to settle for slush" Jan. 25:
Forget about taking responsibility for your actions anymore.
"Officials" and "authorities" take a strong stand against personal responsibility. At least that's what I got out of an article that appeared in Monday's newspaper.
The story, by staff writer Brian Day, had some information that makes clear just how much we've become a nanny state:
About 900 people drove up San Gabriel Canyon Sunday seeking snow.
Unspecified safety concerns caused authorities to close roads above 3,200 feet.
Families hoping to enjoy a day frolicking in fresh fallen snow instead settled for slushy remains at lower elevations.
Gabriel sums up his frustration:
Enough already.
We've allowed anonymous "authorities," "experts" and "officials" to control our lives and turn California into a virtual no-fun zone.
Events in San Gabriel Canyon this weekend and in the state Legislature this month stand as good reminders for us all. California is now a place where... snow is too dangerous.
So we settle for slush.
But it doesn't stop at higher elevation closures. Democrats in the state legislature are now seriously proposing mandatory helmets for California skiiers.
Nanny-statism should be part of California culture says Democrat lawmaker
From the Sac Bee, "Two Bills would require helmets on Ski Slopes" Jan. 25:
California children must wear a helmet to ride a bicycle, skates, skateboard or non-motorized scooter...
The measures by Sacramento Assemblyman Dave Jones and San Francisco Sen. Leland Yee, both Democrats, would make it clear that the constitutional right to pursue happiness does not include skiing bareheaded.
"Lots of Californians take advantage of some wonderful skiing and snowboarding opportunities, and we want to make sure that they are as safe as possible," said Jones, whose bill also targets other aspects of snow-sport safety.
Yee said families would abide by a mandatory ski and snowboard helmet law, realizing that the goal is to reduce the number of head injuries in a sport where one fall can cause permanent harm.
"People will understand that the culture has changed and that (wearing helmets) is the way we do it now," he said.
Republicans, a minority in both houses, have reacted swiftly to oppose the legislation. Continuing:
Opponents criticize the new legislation as "nanny government" in which lawmakers usurp parents in deciding what is best for children.
Sen. Tom Harman, R-Huntington Beach, characterized the proposal as "kind of silly."
"I think it's overregulation," he said. "I'm sensitive to sometimes the government watching out for people, but people need to learn to take care of themselves, and look out for themselves."
Assemblyman Chuck DeVore, R- Irvine, said life and sport inevitably pose risk of injury and overzealous government, left unchecked, someday could require thrill-seekers to wear a full crash helmet and cover themselves in bubble wrap.
"Where do we stop?" DeVore asked.
As of yet, ski enthusiast, Gov. Arnold Schwarzenegger has not indicated where he stands on the proposeld legislation.
Of course, runaway entitlement spending by the Democrat-controlled legislature has also led to state park closures, adding to the woes of winter fun seekers.
California's loss may be other states' gains. Ski Utah anyone?

Last-Minute Leaked Shot of the Apple Tablet: Curiously Plausible [Unconfirmed]
We're about 12 hours away from seeing the thing for real, away from the speculation and leaks, but these two photos popped up just a few minutes ago. We don't know if it's real, but it's definitely possible.
So here's what we can see in these photos, sent by a tipster to Engadget: A tablet in the general form of an iPhone, including the trademark home button, looking like it's encased in some kind of S&M leather case with snaps. It's running what seems to be a larger, scaled version of the iPhone's Google Maps app. In the upper left, it looks like it says "No Service," which would be referencing 3G (also a ha! moment for AT&T, if it uses AT&T) as well as a Wi-Fi logo. Very little else can be ascertained, including the most important pieces of the puzzle, the software and keyboard.
Is it real? It's the most likely suspect in my mind, not least because it only popped up the night before the event—Apple's security is so tight that this is the most leakable time. But it is, right now, unconfirmed.
Stay tuned until tomorrow, when we'll be liveblogging the Apple event from San Francisco. [Engadget]

The Secrets of SkyMall Lie in an Arizona Office Park [Skymall]
Bill Donahue made a trip to the headquarters of SkyMall, purveyors of the most useless gadgetry in the western world (good luck competing with Brando). My favorite part of the article? SkyMall's president is named Christine Aguilera. Ha!
It is kind of an interesting piece, though—SkyMall doesn't make, design, or even (to my surprise) ship products. They just pick and choose their favorites and assemble them into a magazine, and maybe provide some customer service. Mostly, the piece is a portrait of a company that could not be in a worse industry during a recession: Sharper Image and Circuit City have already bit the dust, and SkyMall's profits are way down. But there is a very cheerful-sounding guy working there, and I like their rationale for dismissing a USB-powered air-conditioned shirt:
"You have to unplug it to get up and go to the printer?" Downey said, vaguely incredulous. "I vote no."
"It's a geek shirt," said McCoy. "It wouldn't sell."
Good call, SkyMall. [WorldHum]
