Generating power from heat will soon be dirt cheap


Thermoelectrics — which use wasted heat to generate electricity — could get a lot more interesting thanks to a company called Alphabet Energy. It’s set to commercialize tetrahedrite, a metal that more than doubles the efficiency of current tech for as little as a fiftieth the cost. Thermoelectric materials work thanks to a rare trick: transferring heat poorly while conducting electricity well. However, current materials are pricy and polluting, and only convert about 2.5 percent of heat energy to electricity. Tetrahedrite, meanwhile, could reach 5 to 10 percent efficiency while running a mere $4 per kilogram. Alphabet Energy says it could tap waste heat from industrial plants or even a vehicle’s exhaust system to produce electricity, making it virtually free. That’d mean you could power your car’s cooling AC using wasted heat, ironically — without a solar panel in sight.

[Discussion] Is your Nexus 4 having soft key issues on Android 4.4.4?



Nexus 4 having soft key issues on Android 4.4.4There are currently only a handful of devices that can be updated to Android 4.4.4, including Nexus, Motorola and Sony devices. Of those devices, it’s the ones that are most closely related to Google that have apparently suffered severe teething issues. One particular issue that has been brought to our attention is the fact some Nexus 4 owners have been reporting that their soft keys have stopped functioning after updating to Android 4.4.4. With all of these issues with Android KitKat, Nexus owners have had varied experiences, even with seemingly identical devices, so we’d thought we’d ask: is your Nexus 4 having soft key issues on Android 4.4.4?

Perhaps the most unusual thing about this particular issue is that it appears to manifest as a hardware issue where the bottom of the panel stops operating, and there are pages and pages of users making note of the issue, though it seems entirely up for debate whether the real cause is the Android 4.4.4 update or a deeper hardware issue. There has been no official word on what the root cause of the issue is, and users are reporting very mixed experiences with lodging RMA’s with Google or requesting digitizer replacement from LG. By now, most Nexus 4′s will already be out of warranty, which has created a rather harrowing situation for some users whose device has essentially been rendered useless.


Have you been experiencing any issues on your Nexus 4 on Android 4.4.4? Anything to the degree that is described above? Let us know your story in the comments.

Thanks @Dibang69 for the tip!

UK police begin trialling the world’s fastest face recognition tech


With more than six million CCTV cameras in operation, Britain is the most watched country in the world. London’s police officers are trialling body-worn cameras to help bring about “speedier justice,” but only now are other forces beginning to find efficient ways to process that surveillance. Leicestershire Police today confirmed it has become the first force in the UK to test NEC’s NeoFace face recognition software, which it hopes will “transform the way criminals are tracked down.” NeoFace’s strengths lie in analysing “dozens” of facial features from digital images captured by CCTV or police body cameras and matching them with the 90,000 photos stored on Leicestershire Police’s database.

Because processing only takes a matter of seconds (NeoFace ranks number one in independent face matching speed and accuracy tests), it stands to eliminate the need for officers to manually search for possible matches, which can take hours. Although the face recognition tech is only now making its UK debut, it has already proved invaluable in the US. Just last month, the Chicago Police Department used the system to sort through 4.5 million booking photos to help convict a suspected armed robber. Unfortunately, Leicestershire Police can’t submit NeoFace’s findings as evidence in court — instead it’ll serve as a useful tool to detect possible suspects (and also their family members) and develop new lines of enquiry.

21st Century Fox tried to buy Time Warner for $80 billion — but the main target could be HBO


Could Fox News and CNN have the same owner? No, but close. 21 Century Fox has confirmed reports (first published by the New York Times) that it made an $80 billion bid for fellow media conglomerate Time Warner — and was turned down, for now. Curiously, this comes just as Comcast is trying to swallow Time Warner Cable, but those two similarly-named companies are no longer directly connected. Time Warner (also no longer related to AOL, which owns this website) recently ditched its Time Inc. magazine properties, and now consists of three parts: HBO, Turner and Warner Bros. According to the reports, Fox would sell CNN as part of the buyout to avoid regulatory hurdles caused by owning both large news networks, but as analyst Porter Bibb pointed out on Bloomberg TV, this would give it access to HBO, which he called “the only Netflix fighter left.”

Of course, there’s more to Time Warner than just Game of Thrones and HBO Go. Turner Broadcasting Systems without CNN still has a network of channels like TNT, TBS, Cartoon Network and Turner Sports which has deals for games from the NBA, NCAA Tournament, NASCAR and MLB. The Warner Bros. movie studio is no small fish either, but reports indicate that any combination would keep its operations separate from Twentieth Century Fox. Of course, Fox already has many of those things, except for a premium cable network.

Jawbone takes on Weight Watchers with its latest app update


There are things fitness trackers are generally pretty good at. You know, like counting your steps, measuring how many calories you burned. And then there are things fitness trackers are generally bad at. Logging your food intake is a particularly sore point. After all, it’s not like the onboard sensors can tell when or what you’ve eaten, so you have to go through the tedious business of manually entering all your meals. What’s more, companies like Jawbone and Fitbit aren’t exactly weight-loss specialists, which means their food databases tend to have gaping holes compared to services like Weight Watchers. So, even if you’re disciplined enough to keep a food diary, the thing you ate might not even be in the system. That goes double if you eat out — how are tech companies supposed to know how many calories are in the brownies at that cafe around the corner?

Incidentally, that’s where Jawbone thinks it can do better. The company just released a major update to its iOS app, and it’s all about weight loss. Accordingly, users can now set a weight goal, at which point the app creates a daily calorie target based on your height, goal, current weight and physical activity (remember that the app can log workouts, in addition to your total step count). Unsurprisingly, it would seem existing Up owners have been clamoring for features like this: According to the company, 76 percent of people who use the Up band have a weight goal in mind, and 84 percent of those who log food do so to lose weight. Makes you wonder why Jawbone didn’t address this sooner — rival Fitbit has let you set a weight goal for ages now.

Things get interesting when you actually start to log your food. For one thing, Jawbone lets you batch-add lots of items at once. So, if you had oatmeal, a banana and orange juice for breakfast, you can do a long-press and then add it all in one fell swoop. (If that sounds like a rudimentary feature, consider this: Weight Watchers’ apps still don’t let you do batch-add, and its entire business is centered on weight loss.) Also, Jawbone’s app learns its users’ habits, so it’ll surface foods you eat often. Similarly, if you start to add something like fried eggs, the app will show you foods that other people often eat at the same time. Bacon, for example — people like to eat bacon with eggs.

And now we get to the part where you go to brunch and your tempura oyster frittata isn’t in the food database. So then what? Well, Jawbone’s app now shows listings for local restaurants, and thanks to integration with recipe/food-delivery services like Munchery, PlateJoy, The Orange Chef, HealthyOut and NuMi (coming soon), it can sometimes import the calorie info. Unfortunately, though, if a restaurant isn’t represented there, you’ve got little choice but to turn to crowdsourcing. You could enter the data yourself, for instance, which would involve doing the calorie math on your own (eggs + oysters + home fries). That’s what Weight Watchers users do when they go out, and it isn’t always precise, depending on who’s entering the data. Alternatively, you could ask the restaurant staff about calories, though let’s be real: That’s kind of awkward. Or, the eatery could add its nutritional info through the same back-end service used to aggregate those restaurant listings in the first place. All told, it’s not an especially comprehensive system, but it’s better than nothing: While other apps might include chains like Starbucks, they tend not to offer calorie data for mom-and-pop joints.

Throughout, the app shows how many calories each food item is worth, and you can see at a glance how many calories you “have left,” depending on your daily target. In addition, though, Jawbone has created what it calls a food score, a single number on a scale from 1 to 10 that illustrates how healthy your food choices are. These numbers are color-coded too, so when you see a score of 1.8 for cream cheese in bright red, you know you’ve done something wrong. (Ed. note: If cream cheese is wrong, I don’t want to be right.) Finally, in addition to seeing your rolling food-score average for the day, you can also see how you’ve been doing over longer periods of time. Basically, then, the idea is not just to count your calorie consumption, but also to give you information you can use to possibly even change your habits. To that end, Jawbone is also adding some food-related challenges to its “Today I Will” feature. Think: eating a certain amount of fiber for the day. Yum.

Version 3.2 of the Jawbone Up app is available today, but only on iOS for now. The Android app will receive the same update, according to a company rep, but it’s still in development. So happy downloading, iPhone users, and Android fans, even if you can’t try out the new features today, you might still enjoy Jawbone’s interactive food-pairing table — it’s a pretty good way to waste a few minutes at work. You know, after you’ve had your toasted bagel with cream cheese.

Alleged iPhone 6 Touch ID Fingerprint Sensor Shown Off in New Photos


Nowhereelese.fr (Google Translate) shares some new photos of an alleged Touch ID fingerprint sensor said to be for the iPhone 6. The component appears to be mostly similar in design to the Touch ID component used for the iPhone 5s, aside from relocated screw holes that line up with the metal housing of the device.

Apple supplier Taiwan Semiconductor Manufacturing Company (TSMC) is said to have provided the first batch of fingerprint sensors for the iPhone 6, iPad Air 2 and iPad Mini 3 in May. A report last month noted that these newer Touch ID units would be more durable than the ones currently found in the iPhone 5s thanks to an updated manufacturing process that uses tin.

Higher shipments for Touch ID components would likely help launch supplies for the iPhone 6, as low yield rates of the component were reportedly to blame for the limited supplies of the iPhone 5s last year. The iPhone 6 will likely be announced and launched this September, and is expected to come in two sizes of 4.7-inches and 5.5-inches. However, a recent report suggested that the company is running into production issues with the device, which may lead to the 5.5-inch version launching after October or in early 2015.

The Big Picture: Boeing 787-9 performs extreme maneuvers at Farnborough


Boeing’s original Dreamliner may be old news by now, but a longer variant — the 787-9 — is about to enter passenger service with Air New Zealand. That extended aircraft is also on display for would-be airline customers this week at the Farnborough Airshow, just south of London. With a very light load on board, Boeing’s able to show off its latest plane with some extreme maneuvers, including steep takeoffs and high-bank turns just feet off the ground. The moves may make you uneasy, but they’re designed to demonstrate the aircraft’s flexibility — you won’t experience any of these intense angles on a commercial flight, but you can get a feel for what the new 787 can do in the video after the break.

Hailo’s Uber-like private car service launches in London


Hailo’s long been a friend to London’s black cabbies, giving drivers another way to find punters through its mobile app. With competition from upstart Uber already rubbing black cab drivers up the wrong way, they went as far as vandalizing Hailo’s HQ when the company announced that it, too, was going to launch a private care service in London. Undeterred, the new HailoExec option has started to roll out to Hailo’s iOS and Android apps, meaning you can request a ride in one of the company’s new, in-house fleet of luxury motors. Hailo’s own drivers might not possess the same Knowledge as black cabbies, but getting lost in the labyrinthine streets of London won’t be a burden on your wallet, as you’re quoted the full cost of the journey before you set off.

The new private car service essentially makes Hailo a direct Uber competitor — especially since the latter added a way to hail black cabs from within its app recently. Considering Hailo’s operated relatively uncontested in London and elsewhere, it’s reacting quickly to disruptive new player Uber, even if it’s losing a few friends along the way. Seeming as HailoExec doesn’t calculate fares live, it’s unlikely the Licensed Taxi Drivers Association (LTDA) will be able to use the illegal taximeter argument to give Hailo any bother. Although we do cringe at the thought of another misguided attempt to shut down competition as opposed to, you know, just competing.

Honda’s upgraded ASIMO robot is faster and smarter but still won’t scare Sarah Connor


Honda’s been working on its ASIMO robot for the better part of two decades, but only now is it finally beginning to look like a useful project. The latest version of the droid, similar to the one we saw two years ago, comes with a raft of physical improvements, including new legs that’ll cope with uneven terrain, walk backwards and even run at speeds of nearly six miles an hour. Then there are the redesigned hands, which now have 13 degrees of freedom, enabling the ‘bot to hold and manipulate objects without crushing or dropping them.

It’s not just physical improvements either, since Honda has also been working hard on ASIMO’s artificial intelligence. For instance, the machine can walk around without the aid of an operator, and can observe human behavior and predict the outcome. That means that if ASIMO sees someone hurtling down the corridor, it can work out that it needs to move out of the way. The droid is also capable of picking out multiple voices and faces from crowds and identifying multiple voices when they’re all talking at once. Even more impressively, however, is that the automaton can even communicate in sign language thanks, in part, to those redesigned hands. The only question that remains, of course, is if we’d take one of these over SoftBank’s Pepper? We know that the rival device is nowhere near as useful, but you have to admit, it is a lot cuter.
