Create a Better Emergency Contact Number with Google Voice [Emergency]

Source: http://lifehacker.com/5603492/create-a-better-emergency-contact-number-with-google-voice

Create a Better Emergency Contact Number with Google VoiceEverybody's got a go-to in case of emergency (ICE) contact, but emergencies have a nasty habit of not caring whether your ICE contact is available to pick up the phone. Reader snappingleather's clever solution: Expand your ICE reach with Google Voice.

Use an extra Google Voice number to make an In Case of Emergency contact number that dials multiple family members at once.

A lot of us have more than one Google account (in fact, Google just launched a new feature specifically for multiple account owners), so the idea would be that you set up one of your non-primary accounts with Google Voice, then make that number, when called, ring everyone you'd consider an emergency contact—maybe your significant other, your parents, your sister. The only caveat:

While Google Voice allows you to use two Voice accounts for the same number, you do have to trade off features. That is, let's say your significant other already has a Google Voice account. If you created a new Voice account and set his/her number to ring when that Voice number was dialed, you could do that. But they wouldn't be able to use SMS with their default Voice account. (Then again, if no one you'd list as an ICE contact uses Google Voice, you're in the clear.)

It's a clever idea, and one you could also incorporate with the ICE contact you've already added to your phone.

The Best Things to Buy in August [Buying Guide]

Source: http://lifehacker.com/5602613/the-best-things-to-buy-in-august

The Best Things to Buy in AugustMajor retailers are reminding you it's back to school, back to work, and back to seasons without so much sun. Before you buy what they're selling, consider the nice chunk of change you can save in August with these smartly timed purchases.

Each month, we take a look at the chart and list of the best times to buy anything we compiled back in January and pull out the items you should be on the lookout for that month. Here's a full-size blow-up and cut-out of what to look for this month (click for a larger view):

The Best Things to Buy in August

Now, onto the best deals you can find throughout August. As always, this isn't so much a list of things to "Run out and buy right now," so much as, "Buy this now, rather than later, if you're in the market." Normally we'd include some all-season deals, but in the summer, the best deals are often toward the tail end—big appliances in the post-remodel-season wind-down.

Older computers: John Morris of CNET tells MSN Money that July and August can sometimes yield savings on slightly older computer models, as AMD and Intel's release schedules see computer makers ramping up to release new gear around this time of year.

Laptops: Per Gizmodo's post, and the knowledge that this is when big-box retailers and direct-sale makers start piling on with the back-to-school deals.

Outdoor Toys and Camping Equipment: CNN's Money site quotes eToys.com's Sheliah Gilliland as stating that retailers are eager to move the space-hogging pools, playgrounds, squirt guns, and other summer toys for as much as 65 percent off as the pre-holiday season approaches. Yahoo! Finance suggests it's also a good time to pick up your camping gear.

Kid's Clothing: Because even if you don't have a kid going back to school, you might have a kid you can buy gifts for now. If you do have kids, think beyond the immediate fall needs.

Wines: Somewhat obvious, sure, but you can also lock down some hard-to-find, small-run wines in the early fall harvest season, according to SmartMoney.com.

Linens and Storage Containers: They're aimed at the incoming college crowd this time of year, as AOL Shopping suggests, but you don't need to show a college ID to pick up some things you almost always find yourself in need of.


We're combing the comments of these monthly pieces to see what other deals our readers find during particular months, in the hopes of kicking out an upgraded buying guide in 2011. Got a hot tip on off-season or space-making sales you've seen? Share them in the comments.

Quantum computers could overturn Heisenberg's uncertainty principle [Mad Physics]

Source: http://io9.com/5603298/quantum-computers-could-overturn-heisenbergs-uncertainty-principle

Quantum computers could overturn Heisenberg's uncertainty principleThe uncertainty principle is at the foundation of quantum mechanics: You can measure a particle's position or its velocity, but not both. Now it seems that quantum computer memory could let us violate this rule.

The theoretical underpinnings of the uncertainty principle are, like most things to do with quantum mechanics, extremely difficult to follow and require a minimum of six degrees to really understand, but the great physicist Paul Dirac provided a more concrete illustration of what the uncertainty principle means. He explained that one of the very, very few ways to measure a particle's position is to hit it with a photon and then chart where the photon lands on a detector. That gives you the particle's position, yes, but it's also fundamentally changed its velocity, and the only way to learn that would consequently alter its position.

Now, technically speaking, the uncertainty principle doesn't forbid you from measuring both the position and the velocity of a subatomic particle - it merely prevents you from measuring both with any great precision. It's possible to get a rough idea of both or a highly accurate measure of one, but those are your only options. So you could weaken the photon burst so that the particle's velocity was less affected, but this would give you a fuzzier sense of its position and still change its position, if to a smaller degree than if you set out to measure its position exactly.

That's more or less been the status quo of quantum mechanics since Werner Heisenberg first published his theories in 1927, and no attempts to overturn it - including multiple by Albert Einstein himself - proved successful. But now five physicists from Germany, Switzerland, and Canada hope to succeed where the father of relativity failed. If they're successful, it will be because of something that wasn't even theorized until decades after Einstein's death: quantum computers.

Key to quantum computers are qubits, the individual units of quantum memory. A particle would need to be entangled with a quantum memory large enough to hold all its possible states and degrees of freedom. Then, the particle would be separated and one of its features measured. If, say, its position was measured, then the researcher would tell the keeper of the quantum memory to measure its velocity.

Because the uncertainty principle wouldn't extend from the particle to the memory, it wouldn't prevent the keeper from measuring this second figure, allowing for exact (or possibly, for obscure mathematical reasons, almost exact) measurements of both figures in flagrant disregard of Heisenberg's principle. If this wouldn't destroy uncertainty completely, at the very least it would fundamentally alter our understanding of quantum mechanics and particle physics. (It might even reopen the possibility of that interstellar ansible, but you didn't hear that from me.)

The mathematics of all this appears to be sound, but we're still a long way from testing it in the laboratory. It would take lots of qubits - far more than the dozen or so we've so far been able to generate at any one time - to entangle all that quantum information from a particle, and the task of entangling so many qubits together would be extremely fragile and tricky. Not impossibly tricky, mind you, but still way beyond what we can do now. Quantum computers better be ready the day they come online, because we've got one hell of a to-do list waiting for them.

Apple Security Breach Gives Complete Access to Your iPhone [Security]

Source: http://gizmodo.com/5603319/new-apple-security-breach-gives-complete-access-to-your-iphone

iphone-pacman.jpgRight now, if you visit a web page and load a simple PDF file, you may give total control of your iPhone, iPod touch, or iPad to a hacker. The security bug affects all devices running iOS 3.1.2 and higher.

Update: Initially we thought that this exploit only effected iOS4 devices, but it turns out all iPhones, iPod Touches and iPads running 3.1.2 and higher are susceptible.

The vulnerability is easily exploitable. In fact, the latest one-click, no-computer-required Jailbreak solution for iOS 4 devices uses this same method to break Apple's own security (although in a completely benign way for the user).

How it works

It just requires the user to visit a web address using Safari. The web site can automatically load a simple PDF document, which contains a font that hides a special program. When your iOS device tries to display the PDF file, that font causes something called stack overflow, a technical condition that allows the secret ninja code inside the font to gain complete control of your device.

The result is that, without any user intervention whatsoever, that program can do whatever it wants inside your iPhone, iPod touch or iPad. Anything you can imagine: Delete files, transmit files, install programs running on the background that can monitor your actions... anything can be done.

This is not the first time that something similar has happened. At the beginning of the iPhone's life there was a problem with TIFF files that also caused the same security breach. Apple patched the bug after a while, but back then there were very few iPhones compared to the current installed base. Apple says that there are 100 million iPhones, iPod touches, and iPads in the world. Obviously, malicious hackers are racing to get a slice of that market.

How can you avoid it?

Right now, the easiest way to avoid this problem is by not going to any PDF links directly and not loading any PDF from any non-trusted source.

You can also jailbreak your iPhone and install a program that will ask for authorization every time your browser encounters a PDF (just look for "PDF loading warner" in Cydia).

Apple Security Breach Gives Complete Access to Your iPhone

While this doesn't solve the security problem at all, at least it will remind you every single time.

Apple hasn't commented on the situation yet. [Macstories and Digdog]

BlackBerry Torch Impressions: The BlackBerry, Weirdly Evolved [Blackberry Torch 9800]

Source: http://gizmodo.com/5603176/blackberry-torch-impressions-the-blackberry-weirdly-evolved

BlackBerry Torch Impressions: The BlackBerry, Weirdly EvolvedBlackBerry Torch. The name of the phone that RIM hopes will revitalize BlackBerry is so metaphorically heavy handed that it almost inflicts blunt-force trauma. The iconic BlackBerry metastasized into a slider with sparkly new software, it's wonderfully weird.

Imagine any BlackBerry released in the last year. Now imagine that the screen and trackpad sprouted downward, uncontrollably, until it reached the bottom of the phone, completely smothering the keyboard. Then a seam appeared at the bottom. You push up with your thumb, and the screen smoothly slides along a track for a quarter of a second before shooting skyward, clacking into place. Solid, is how it feels. Now it's 30 percent taller, the touchscreen, trackpad and four ever-present BlackBerry buttons floating above the keyboard you've probably always loved. But this whole production is hardly thicker than the BlackBerrys that don't split in two. That's the Torch. At first glance, it looks, feels, is almost exactly like any other BlackBerry released in the last year, except that it happens to be a revival of the vertical slider—a squarer, better constructed exploration of what the Pre tried to accomplish. Oh, and the ridged, ripple-y rubber back is nice. I'm pretty sure you'll never drop it.

BlackBerry Torch Impressions: The BlackBerry, Weirdly EvolvedAn immediate disappointment in a world where 800x480 has become the default display resolution for anything that credibly claims to a decently equipped phone is the Torch's 3.2-inch screen, whose resolution is a mere 480x360. You could try to make the argument you don't need a super high res screen for a mostly text-oriented, and I would direct your crazy eyeballs to the screens on the iPhone 4 or the original Droid screen, where text is super crispy, and simply awesome to read. It's jarring after staring at those phones to see such jaggy-looking text—it's like staring back at 2006, but with cataracts. (Not to mention, it's clearly trying to be way more than just a corporate email device.)

BlackBerry Torch Impressions: The BlackBerry, Weirdly EvolvedThe keyboard is, like most of the new keyboards RIM designs, a marvel. Their thinnest keyboard ever, it types just like the current BlackBerry Bold, and the overall balance of the phone when it's popped open makes typing effortless and natural—it really is exactly what you'd expect from a BlackBerry. The touch keyboard feels usable. The words "not bad" stick in my mind.

It is odd, though. Almost schizo, really: a (non-clicky) touchscreen; a full keyboard; an optical trackpad. Conceptually, the Torch really begins to make sense in context as a product of RIM's particular psychology. The Nielsen numbers released yesterday might illuminate what that is: Over the last year, BlackBerry's marketshare in the US has crept downward as Android's exploded and iOS has steadily inched up. More importantly—if Nielsen's polling is worth a crap—while the overwhelming majority of current iPhone and Android owners plan on sticking with their phones, a majority of BlackBerry owners say their next phone is going to be Android or iPhone. It's a fine recipe for an existential crisis.

BlackBerry Torch Impressions: The BlackBerry, Weirdly EvolvedSo, you immediately get the sense that the Torch is a flagship for RIM in the same way that the T-Mobile G1 was for Google when it launched Android nearly two years ago—the phone had to do everything, be anything, to any developer or consumer, since it was it was trying to launch a brand new platform. In this case, RIM's trying to re-launch BlackBerry, with OS 6, which has the deeply unenviable task of trying to be great for suits—BlackBerry's lifeblood—and dudes in jeans. The catch is that BlackBerry, from the beginning, has been truly designed for the former—I mean, the BlackBerry feature getting it kicked out of the UAE is the security of its communications, not its beautiful, easy-to-use interface—it's just happened to have been adopted by lots of normal people in the meantime. Microsoft, confronted with the same existential problem with Windows Mobile—does it exist for businesses or for people? Both?—ultimately punted, and started from scratch with Windows Phone 7, aiming primarily at consumers. (Remember it too had decent marketshare, once upon a time.) That's where RIM sort of finds itself: Can it do both?

BlackBerry 6, it's quickly apparent, is not a clean start. It's still very much a BlackBerry. Which is the point, as RIM's director of user experience research made clear on BlackBerry's official blog a week ago. "Fresh, but familiar" is the goal. The interface, initially, is very reminiscent of the Storm 2, even in the little ways it seems slightly cleaned up. What's seriously noticeable is that the home screen now uses a drawer metaphor—a handful of icons are visible, and you drag up to reveal everything hidden below. Flicking left or right takes you to a different "drawer" (or "panel," in Android parlance). Each one is a section, like frequent apps, media apps, or downloaded apps. It's not very immediately obvious what to do—I guessed, having used Android so much. Universal search is finally on BlackBerry, so you can just start typing and finding stuff, which is a good thing. Otherwise, it looks and feels very "familiar," as RIM is wont to say.

BlackBerry's gambit into handling your social networking in a better, integrated way—as webOS, and most recently Android, have tried to do—is a new social feeds app that drags Twitter, Facebook, MySpace, other apps and even RSS into a single feed, which is itself integrated into BlackBerry's central universal inbox (aka "Messages"). (So, "Messages" includes email, SMS, MMS and if you want, messages and updates from social networking apps.) Oh, and like Android, the official Facebook and Twitter apps are baked in. (Along with apps for Google Talk and AIM and others.)

Oh yes, the much-ballyhooed WebKit browser. It is, from the second you fire it up, quite obvously better than any BlackBerry browsers ever. Faster, more competent, and pinch-to-zoomy. Zooming is a little choppy on Gizmodo's heavy page, but still totally usable and dandy. The start page is cleaner, showing simply bookmarks and history, with an integrated search + address bar. It's hard to tell how decently it stacks up against iOS and Android's browser without more extensive testing.

BlackBerry Torch Impressions: The BlackBerry, Weirdly EvolvedIt's loaded with BlackBerry App World 2.0. Going off memory, it looks just like 1.0? So it could be better, it seems. (The main features are under the hood improvements, anyway.) Here's something crazy: This phone also has a separate AT&T app store. Oh, and there's no BlackBerry Maps, just AT&T Maps. This could be messy! The music player is updated with a faux Cover Flow, which is weird, since it appears to be active at all times. That is, you can page through album art at any time, so it works like skipping a track. Speaking of music, what I'm most excited about, really, is wireless syncing. (Why doesn't everybody do this, again?)

The email app looks about the same overall, though it's using WebKit as a rendering engine, for emails with fancier formatting. The very beautiful Outlook mail app for Windows Phone 7 makes it look kinda old and washed up, which has a tragic subtext to it, since BlackBerry is supposed to be all about email. The lower res screen of the Torch doesn't help here—reading doesn't feel nice, the way it really should on this thing, at least not initially.

There's a lot more to dig into, but a few things are clear right now. The Torch and BlackBerry OS 6 take what BlackBerry's already doing and move it forward slightly—they're not reinventing, overturning, or blowing up things. Even the sorta kinda half-crazy slider design of the Torch feels fundamentally like a BlackBerry, just a leeeeettle different. Which is fine, in a way—existing BlackBerry users who just want the same thing will probably love this. But is that enough anymore? Here's the question: Do people simply want a better BlackBerry or do they want something else, something completely new that also happens to be good at all the things BlackBerry is good at? I suppose we'll find out.
