Do You Want Restaurants Following You on Twitter?

This receipt is from a restaurant in San Francisco. Typical. On one hand, the thought of a restaurant following you on Twitter and Instagram, stalking you, liking your arty snapshots and faving your 140-character quips is obnoxious. And on the other hand, gift cards.

Does this annoy you? Or do you even care if restaurants want to follow you? More here.

Starbucks to Open 1500 More Locations for You to Find Free Wi-Fi

Starbucks announced today that it was opening 1,500 more stores in the U.S. over the next five years. For some this means more places to buy coffee, for others it means 1,500 more places to find free Wi-Fi.

It appears that the gigantic coffee seller is going to do something about that, and according to USA Today, it announced at its most recent investor day that it would be opening another 1,500 locations over the next five years through out the U.S. Canada, South America and China are also prime targets for further expansion. More here.

America Is Just So Beautiful at Night

NASA's Suomi NPP satellite was able to grab this beautiful image of the United States of America at night because of a new infrared sensor on the satellite. The sensor is able to detect natural light versus man-made light at extremely high resolution. That's how you get this perfect image of Earth at night.

Wired writes:

The Visible Infrared Imaging Radiometer Suite has a "day-night band" that can detect natural and man-made light with unprecedented resolution and clarity. It can resolve everything from the nocturnal glow of the atmosphere to the light of a single boat at sea. It can detect auroras, wildfires, the reflection of moon and star light off clouds and ice and the lights alongside highways. The sensor has six times better spatial resolution and 250 times better resolution of lighting levels than anything that came before it.

What's interesting is that the pictures from the Suomi satellite are available to the public, giving most people the clearest look of Earth at night ever. Before, the Air Forced had nighttime sattelites in play but most of the data was classified and not nearly as clear as the image above. To see more angles that the Suomi satellite was able to take, check it out here

A USB Flash Drive That Might Be More Beautiful Than a MacBook

This sleek flash drive is the perfect complement to your beloved Apple hardware, even going so far as to match its silvery finish.

Available in 16 and 32GB capacities for $60 and $82 respectively, these ultra-compact flash drives from Elecom add a bit of stylish extra storage to your hardware. And given their compact cylindrical design sits flush to the edge of your laptop, in theory you'll never need, or want, to remove it. Besides, why would you ever lend it to someone and risk never getting it back? More here.

Grand Theft Auto: Vice City Now Available for iOS

Grand Theft Auto: Vice City is now available for the iPod touch, iPad and iPhone, as expected. Oddly, however, Rockstar hasn’t yet released the Android version, which was also due out today. The game has been tailored specifically for touchscreen devices and features updated graphics with improved character models and lighting effects, the ability to save games to iCloud, support for Retina displays and the option to play your own iTunes playlists. Here’s a bit about the game:

From the decade of big hair, excess and pastel suits comes a story of one man’s rise to the top of the criminal pile. Vice City, a huge urban sprawl ranging from the beach to the swamps and the glitz to the ghetto, was one of the most varied, complete and alive digital cities ever created. Combining open-world gameplay with a character driven narrative, you arrive in a town brimming with delights and degradation and given the opportunity to take it over as you choose.  More here.

Secret Elixir Makes Any Glove Touchscreen-Friendly

By now it's almost impossible to find a winter glove that doesn't work with touchscreen devices. But if you've got a favorite pair that predates the iPhone, this AnyGlove potion will let you use them with a touchscreen display without having to resort to sewing conductive thread onto the fingertips.

Just a few drops is all that's needed for your smartphone or tablet to recognize your gloved gestures. And while the liquid might stain lighter colored fabrics or yarns, it's completely invisible on darker materials. It's not permanent, though, you'll need to reapply the AnyGlove elixir as often as every few days depending on how active you are in your gloves. But a single $15 bottle should last until the warm summer returns. More here.

The Mathematical Formula For a Perfectly Decorated Christmas Tree

It turns out that decorating your Christmas tree isn't necessarily all about taste. Mathematicians at the University of Sheffield in the UK have developed a formula for the perfect way to deck the halls. More specifically, what ratio of ornaments to lights to tinsel will make your tree most aesthetically pleasing.

Since the geniuses behind the formula hail from the UK and embrace that new-fangled metric system, you'll need to know the height of your tree in centimeters. But you're just a tape measure away from having the data you need to use their handy online calculator. Did you know your average six foot tree only needs 37 ornaments to look its best? More here.

Wireless Card Reader Lets You Share Your Shots Without Stupid Cables

Wireless devices are usually far more convenient than their tethered alternative. But in this case losing the USB cable has made the REX-WIFISD1 SD/SDHX/SDXC and flash drive reader a bit on the bulky side. So what do you really gain for it being wireless? The ability to access it from any mobile device.

Apple already sells a memory card adapter for its iOS devices, but this is a more universal solution letting Android hardware and Windows/Mac PCs access the data from an attached storage device. Of course the onboard wireless hardware is powered by a 3,000 mAh battery, which should give upwards of nine hours of operation. And not surprisingly, given the extra functionality the REX-WIFISD1 is priced bit higher than your average card reader at $97. So is this one worth importing? If you abhor cables the answer is obvious. More here.

Feel Free To Spill Whatever You Want On This Waterproof PC

You can be as reckless as you want with your bottle of Moutain Dew around Stealth's new fanless WPC-525F computer. As the name implies it relies on its aluminum chassis as one large heatsink to dissipate high temperatures.

So besides near silent operation, it's also sealed making it completely waterproof and dustproof. The $1,595 base configuration comes with an Intel Dual-Core D525 processor running at 1.8GHz, 4GB of DDR3 memory, and a 120GB SSD so there's basically no moving parts inside. And in order to provide connectivity like USB, video, and LAN while keeping water out, the case uses watertight bayonet connections and adapter cables. So if one unfortunately wears out, they're not exactly common or easy to replace at your local computer shop. More here.

This Is Now the Coolest Microwave of All

Sure, this other microwave is "the most beautiful," and it certainly is "classy," "modern," and maybe even "timeless." But this microwave is a god damn dome. And because it's a dome, it wins it all. It wins microwaves.

The Fagor Spoutnik has two major things going for it: it's called the Spoutnik and it has a dome cover. Also, sike, it has three things going for it: it comes in a ton of wacky colors. Green! Purple! It does everything you'd expect from a microwave—cooking things, cooking things with a timer, etc.—but it does all of it under a dome. This does serve some functional purpose besides being a sweet rainbow dome: you can get a 360-degree view of what you're cooking, and fit odd-shaped foods that might not fit in a rectangle. The microwave used to be a symbol of Space Age luxury—and now that it's no longer a luxury, we can at least pretend we're living in The Jetsons. More here.

Would You Trust a Doctor Checking Your Heart with an iPhone?

Meet the Alivecor Heart Monitor iPhone case. The FDA just approved it. Affordable electrocardiogram (ECG) screening is actually a real need (the AliveCor monitor is just $200), even though you've probably never heard of it. Failure of the ECG screens to detect underlying heart conditions is suspected to have led to many young athletes going into cardiac arrest, and sometimes death. Children's lives literally depend on these things. And being FDA-approved is about as good an endorsement as you can get.

Appending sensors onto the computing power of a device you probably already have is a fine and efficient idea. There are other medical iPhone uses, like blood sugar tests for diabetics, or simple heart monitors. And again, AliveCor has all of the backing of the FDA, as well as the encouraging responses from the American Heart Association and American College of Cardiology. More here.

It Takes 20 Seconds Before People Get Annoyed About Waiting for the Elevator

Theresa Christy, a mathematician who works for Otis Elevator Co (they probably power your building), told the WSJ that once you press a button and wait for the elevator, it takes about 20 seconds before you start getting impatient and annoyed.

Is that it? Or is that on the long side? If I imagine a 20-second count in my head, it seems on the long side. But if I can see the elevator light up the floors, maybe it's not so long. What do you guys think?

Christy actually revealed a lot of interesting tidbits about elevators and how they work and solve problems with math. Like how to tweak elevator speed to accomodate more rides, how many people squeeze into elevators in Western Countries versus Asia and how she uses a computer simulation program that replays elevator decision making (like a video game!) to analyze what to do.

How To Easily Build the Most Useful Keychain You’ve Ever Owned

If you've got access to a bucket of Lego Technic pieces, then you've probably already got everything you need to build what could possibly be the most useful keychains ever devised. As for the building instructions, just take a look at the image above and you'll easily figure it out.

It's cheap, it's compact, and removing a single key doesn't require you to tear your fingernails to shreds trying to pry open a keyring. And because Lego is produced to such exacting dimensions, there's little to no chance this thing is going to come apart until you want it to. As a bonus it's even easier to build a spot to hang the keychain when you get home—just stick a Lego baseplate to the wall near your front door. Done. More here.

Insane Blasts of Heat Could Make Flash Memory Live Longer Than Ever

Flash memory is fast, it's stable, but it's not without its flaws. It has a tendency to wear out after too many write-erase cycles, for example. Now there's a way to deal with that problem, and it could lead to self-healing NAND flash memory that could last for much, much longer than the stuff we have now.

The discovery comes from Taiwan-based company Macronix who realized that the key to long-lasting NAND memory is the strategic application of heat. If you bake the memory at a heat of around 480 degrees Fahrenheit for a few hours, you can breathe some of the life back into it. The problem is that isn't exactly practical.

Macronix is working on a solution that is more practical, though: a chip with on-board heaters. Instead of baking the whole chip, it would jolt unused-but-aging sectors with a super blast of heat (about 1,400 degrees) every now and then. This could give chips a lifespan of roughly 100 million cycles, orders of magnitude more than the current highs of 100,000 to 1 million.

Before you get too excited, commercial versions are not inbound yet. Macronix will instead be presenting the tech at the IEEE International Electron Devices Meeting. It's still an exciting development nonetheless and is sure to make it into consumer goodies sooner or later. Hopefully sooner. More here.

This Minimalist Christmas Tree Is Great for the Irredeemably Lazy

Christmas is coming. The goose is getting fat and whatnot. Maybe you're in the market for a Christmas tree, maybe you're not. Maybe you'd like to be in said market, but you are extremely, extremely lazy. Treeasy's got your back, that is, if you don't mind something bare and metallic.

Designed by José Manuel Rebert Alarcon, Treeasy (in addition to being a halfway decent pun) is a single sheet of aluminum cut just so that you can just push it from the bottom and it pops out into a little Christmas tree with almost no effort involved. Granted, it's not your standard Christmas tree by any means, but if you're sufficiently lazy—but can't just not have a tree of some sort for some reason—Treeasy is at least identifiably tree-like, and kind of clever. More here.

Raspberry Pi's $25 Model A Enters Production, Could be in Tinkerers' Projects Early Next Year

Raspberry Pi's Model B computer will be no stranger to regular readers. If you were holding out for the cheaper, lower specced Model A however, your time is near. A recent post on the official Raspberry Pi site confirms that the first Model A samples are rolling off the production line. The main differences? 

Whereas Model B has two USB ports and 512 MB of RAM plus Ethernet, Model A sports only the one port, has half the RAM, and no Ethernet connection, making it more power economical as well as $10 cheaper. Price likely isn't the issue here, but if you were after the even more stripped back version, it's estimated they'll be ready to purchase online early next year. More here.

Hi-Tech Parenting: The DIY Kid-Tracking Surveillance Copter

Parents can be unnerved by the thought of sending their children off to school by themselves. In the past, that usually meant walking the child or following close behind, diving behind bushes to avoid embarrassing the tot. Now, it involves something else — a quadcopter, a GPS signaler and a little know-how.

Paul Wallich rigged a drone with a camera and then stashed the GPS unit in his son’s backpack. Using navigation software, he made sure the copter would stay a certain distance behind the child as it followed the kid to the bus stop.

In concept, it’s a brilliant stroke of hi-tech parenting that allows Wallich to keep an eye on his son remotely. But as a real-world safety measure, it’s questionable. It’s one thing to make sure dangerous strangers don’t approach the boy, but it’s another when the surveillance/tracking copter makes him a target for bullies. More here.

Researchers Can Make Bread Stay Fresh for 60 Days

Most foods deteriorate over time, but bread's a major culprit, often going stale after just a couple of days. Now, though, a US research company claims to be able to make your loaf stay fresh for up to 60 whole days.

The secret? Um, a gigantic microwave. No, seriously. The company, called—wait for it—Microzap, has developed a long, metallic microwave device for the purpose. The concept was orignally developed to kill bacteria like salmonella, but the team put a slice of bread through the thing and noticed it didn't go stale. In fact, even after 60 days the bread "had the same mould content as it had when it came out of the oven." Nice!

Crucially, this microwave is a little fancier than the one in your kitchen. Don Stull from Microzap explained to the BBC:

"We introduce the microwave frequencies in different ways, through a slotted radiator. We get a basically homogeneous signal density in our chamber - in other words, we don't get the hot and cold spots you get in your home microwave."

Of course, it remains to be seen whether consumers want bread that lasts for 60 days. There's something about the concept that seems a little unnerving—but what price a fresh sandwich? More here.

This Portable Bluetooth Speaker Is Different Because It Looks Weird and You Can’t Break it

The world is seething with a billion cheap, portable Bluetooth speakers. To differentiate itself from the pack, Boom Movement has created this thing. It's called the Urchin, and the silicone cloaked beast looks as bizarre as its name implies. It's also certified shock and water-resistant.

The Urchin will cost $150 when it's available at the beginning of February. Additional colorful silicone covers will be available for 20 bucks a pop, if dressing up consumer electronics is your thing.

Boom Movement's audio and design pedigree is impressive: It's an offshoot of the same company that owns undeniably legit Polk Audio. The Urchin is supposedly designed to maximize the full-range potential of its pair of dinky speakers with minimum distortion.

But even if The Urchin sounds better than the competition, you have to wonder if that's going to be enough to help it stand out from the other $150 Bluetooth numbers out there. If not, maybe people will find it while searching for an odd, indestructible fashion statement. More here.
