Latest Technology / The best smartphone camera accessories
« on: June 09, 2018, 11:03:47 AM »
The two best ways to improve your smartphone photography are "talent" and "practice," but if you'd rather buy your way to better shots, that works too. Nowadays, there's a great selection of accessories like clip-on lenses, stabilizers, stands and other gear you can get without blowing a hole in your budget. If you've been thinking about taking that next step, here are a few questions to ask yourself and some of the best products on the market.

Smartphone photography has become so good that you might rightly question whether you need accessories at all. Devices from Apple, Samsung, Sony, LG and Google can achieve a level of quality that was unthinkable just two years ago. Even second-tier manufacturers like Huawei (above) and OnePlus offer dual-camera systems that are as good as if not better than the big brands.

Smartphone makers have stolen some lens accessory business by introducing multi-camera phones and reducing the need for stabilizers with better built-in OIS systems. That said, however, none have truly wide-angle or telephoto lenses, nor could you do any serious video tracking shots with a smartphone alone, sans stabilizer.

So there's still a need for accessories to fill in the gaps of what your smartphone camera can't do. With a few well-chosen ones, you can drastically improve your videos and photos for social media and other purposes.

Clip-on lenses
Smartphone lenses are better than ever, but there's only so much you can do with parts that are less than a centimeter across. That's where clip-on lenses come in. The extra glass can let in a lot more light and give you better control of exposure, color temperature and other parameters via the apps.

Some lenses, like ones from Olloclip and Aukey, are relatively simple affairs that clip directly to your phone, while others, like models from Moment, require a case for your specific model of phone. Bear in mind that none of the lenses will improve the clarity of your photos, as the light still passes through the smartphone's built-in lens. They can make the quality worse, though, if you buy a cheaply built lens.

If you do want better quality, with a much bigger sensor and lens and a smartphone's ease of sharing, then you'll need something like the DxO One. That's essentially a stand-alone camera -- with its own sensor, lens and aperture -- that's powered by your smartphone via an app. Those are great, but the DxO one runs over $500, so you might as well just buy a really good compact camera like Sony's RX100 Mark III, which can currently be found for just over $600.

Moment lenses
Most smartphone photo nuts agree that Moment is at the top of the clip-on lens heap. The company, which first came on the scene via Kickstarter in 2014, recently released new versions of its five lenses (superfish fisheye, wide, tele portrait, anamorphic and macro). It also launched new cases that attach them more firmly and work with the latest iPhone, Pixel and Samsung Galaxy smartphones.

The lenses are a bit pricey (between $90 and $100 and up to $120 for the anamorphic lens, plus another $30 for the case, or more for the battery cases), but the glass construction and multi-element design provides some of the best image quality you can get on a smartphone. Built with aerospace-grade metal, they attach easily and firmly to the phone case with a twist, just like on a DSLR. The app is also easy to use and gives you more control than you'd get with most built-in smartphone camera apps.

That said, Moment touts the tele portrait lens as being sharp in the middle but deliberately soft on the edges, to give a slightly dreamy look. So if you don't want the soft edges for portraits, you're better off sticking with your smartphone camera.

Olloclip
Olloclip works only on the iPhone, even though Samsung, Google and others are making arguably better smartphone cameras now. If you're using an Apple device, however, it has a lot to offer. For $100, you can get the Core Lens set for iPhone 7/7 Plus or 8/8 Plus, which includes a fisheye, 15x macro and super-wide lens. The same lens set is also available for the iPhone X, but it's called the "Mobile Photography Box."

Much like with the Moment, it comes with its own app that extends what you can do with the regular smartphone camera app. It's got great optics for the price, and you don't need to buy a case to attach the lenses like you do with Moment. However, you can't use both lenses on the iPhone 7 Plus and 8 Plus models, and it doesn't work with most iPhone cases. If you can live with those limits, and the fact that it's iPhone only, Olloclip will improve your smartphone photography on the cheap.

Aukey Ora lens kit
If you're toying with the idea of clip-on lenses, but not seriously enough to drop a C-note or more, Aukey's Ora kit might do the trick. For just $20, you get a 140-degree wide-angle lens, plus a 10x macro lens for close-up shots. The housings are built from aluminum alloy, the glass is coated to prevent ghosting and flares and the grip has rubber contacts to minimize slipping on your phone. What's more, it works with a number of smartphones, including the iPhone 8.

Stabilizers
If you want to do Facebook Live or Periscope videos without shaky video, you'll need to consider a smartphone stabilizer at some point. Available in both manual and motorized versions, they remove all the bumps and jerks in your shooting, letting you create a more cinematic experience. Just remember they're not a magic bullet -- it takes some practice to get the kinds of results you'll see on YouTube.

Zhiyun Smooth 4
The Zhiyun Smooth 4 is at the top of most smartphone videographers' lists, because it's well built and does a lot for the money. It's made from metal (unlike the DJI Osmo Mobile 2), it's fairly lightweight and it can handle any phone with up to a 7-inch screen (up to 500 grams, or 1.1 pounds). It offers two-way charging, so you can juice it with a portable charger while charging your phone at the same time.

What separates it from the pack, though, is all the features. Multiple triggers let you instantly set different follow modes: PhoneGo mode for instant scene transitions or a locked-off mode for quick movements. The side wheel lets you pull focus or zoom, while the control panel offers options for POV orbiting, time lapse or "vertigo shots" (dollying in while zooming out, the effect that Hitchcock made famous). You get all that for $149, making it a no-brainer for serious smartphone videographers.

DJI Osmo Mobile 2
DJI helped popularize smartphone stabilization with the original Osmo and Osmo Mobile (at top), but the latter is pretty costly at $299 and doesn't work great with large phones. At CES 2018, it launched the much cheaper $129 Osmo Mobile 2, which is now built from high-strength nylon instead of metal. You can't hot-swap the battery on the Mobile 2 as you could with the original, but there's less need, as the built-in battery can last three times longer -- up to 15 hours.

Unlike on the Zhiyun Smooth 4, the controls are pretty basic, though you might argue that this makes it easier to learn and operate. You can also quickly re-center it by double-tapping the mode button, an operation that's harder to do on the Smooth 4. It's easy and quick to switch to the front camera button, making vlogging a relative snap. Unfortunately, to switch the camera to portrait mode for Instagram stories, you need to manually remove it and flip it around. Otherwise, it's better than the original in every way, and also cheaper.

Other accessories
Smartphone photography has a few other weak points besides the lenses and stabilization systems. It's nice to have something to hold your phone if you're a one-man videographer, for instance, and the flash and microphone quality still isn't great. These last few accessories can fill all of those holes.

Joby GripTight GorillaPod

Joby's flexible tabletop GorillaPod tripods have long been popular with videographers, especially vloggers, because they act as a convenient handle and tripod in one. The GripTight GorillaPod can handle any smartphone measuring 66 to 99 mm (2.6 to 3.9 inches) -- just pull the clamp open, insert your phone and tighten the screw. Then you can set it on rocks or other uneven surfaces or even wrap it around a tree, giving you an instant camera mount. It's just 12 inches tall and weighs 2.4 ounces, so it can travel anywhere, and at $30, it's a must-have accessory for smartphone videographers and photographers.

iBlazr 2 LED light

When extolling the virtues of their cameras, most smartphone manufacturers don't talk about the flash. Suffice to say, most are pretty dim, so if you're doing a lot of night shooting, you could probably use some help. The 3.5-ounce, $50 iBlzr 2 has four LED lights that can clamp to the top of your iOS or Android phone and sync to the stock cameras over Bluetooth. It can extend your shooting distance by 80 feet, compensate for indoor lighting, and handle 300 flashes or three hours of continuous light on a charge.

Rode VideoMicro and VideoMic ME
Another thing you don't hear a lot about is the quality of your smartphone's built-in microphone. Most aren't acceptable for anything approaching professional video, and that's where Rode's VideoMicro and VideoMic ME come in. Both are around $60 and include a (hilariously big) furry windshield, but the latter is just for smartphones, and the VideoMicro can also be used on a camera. Both focus the sound in front of the camera, reducing peripheral and rear noise. You can even plug in a set of headphones so you can monitor the sound quality in real time.

Wrap-up
With all the excellent smartphones released over the past year, everyone has a camera in their pocket. What compromises do remain can be addressed with a lot of the gadgets mentioned here. While some of them are expensive, it's a heck of a lot cheaper than buying a new compact camera, and the results you'll get will be nearly as good.

Google's rumored (but really, expected) Pixel 3 XL may have become much more tangible. An XDA forum goer has posted photos of what appears to be a test unit for the Android P flagship, and it largely supports earlier leaks, including the edge-to-edge screen -- yes, there's an unusually deep notch with two front cameras. The rear is less polarizing, but the curvier-than-usual shape suggests there might be a glass back, or at least something slightly more fanciful than on Pixel 2 devices.

The firmware suggests there won't be any dramatic leaps forward in specs. This developer model comes with 4GB of RAM and 128GB of storage, which isn't that much different than the existing phone. It's possible Google could bump up the specs, but we wouldn't count on it given that the company has likely locked down the design at this point

If a previous Bloomberg scoop was accurate, you could expect to see the finished version of the phone in October. The main question at this stage is pricing. Will the new screen command a premium, or will Google try to keep costs in check? We wouldn't expect a price hike given that most features seem familiar, but it's difficult to rule anything out.

2016's Hitman refresh from IO Interactive was a watershed moment for the long-running assassination and stealth game series. Even as the developer was essentially cut loose from Square Enix, it retained ownership over the franchise, signing a new publishing deal with Warner Bros. Now the company is ready to launch the next iteration in the popular stealth series. Hitman 2 will be released for PlayStation, Xbox and PC on November 13, 2018.

Agent 47 is back in this new adventure, which the developer promises will be a hyper-detailed sandbox of international locales to explore while planning the ultimate assassinations. You'll get the requisite arsenal, stealth techniques and a wardrobe full of disguises to creatively end each of your your targets' lives. There's also a new Sniper Assassin mode (trailer below) that lets you work alone or with a buddy to take down your target. You can try it out as an early bonus if you pre-order Hitman 2's Standard, Silver, Gold, or Collector's Edition. The last two options will also net you access to the game four days before the official release.

If a company isn't talking about the transformation of transportation there's a good chance it might get caught flat-footed when cars start driving themselves loaded with battery packs. Mostly these conversations center around passenger vehicles, but trucks could do with some cleaning up, too, and one of the companies on the forefront of that is Daimler.

The parent company of Mercedes-Benz, Fuso, Freightliner, bus-maker Thomas and a whole host of other companies is investing heavily in electrified trucks. It's easy to imagine that most semis we see on the highway are enduring multistate treks. In reality, most of those big trucks -- especially in areas near ports and railroad hubs -- are transferring freight from those locations to warehouses, where they'll reach their final destination via smaller trucks.

It's those local trucks Daimler is electrifying and at an event in Portland, Oregon, yesterday it unveiled two electric freight-hauling machines. The larger of the two -- and what you imagine when you think big rig -- is the heavy duty class 8 eCascadia (based on the diesel Freightliner Casadia line). For local deliveries, the company showed off the smaller eM2 which is based on the ... you guessed it, Freightliner M2 line.

Both trucks have ranges over 200 miles (eCascadia will go up to 250 miles while eM2 tops out at 230 on a full charge). For those trucks that travel about 150 miles per day, electrification makes a lot of sense. Daimler isn't putting these trucks into production just yet though, first it's handing out 30 to select customers this fall.

"They'll be tested with real customers, with real freight on real American highways. That'll give us the learning we need to understand the durability of the batteries," Roger Nielsen, CEO of Daimler Trucks North America told Engadget.

No one knows how well battery packs will fare on a big truck after 500,000 miles, not to mention 1 million miles of heavy-duty use, according to Nielsen. Can they survive that type of nonstop punishment? That's what Daimler hopes to find out during its tests with partners.

While it's working on bringing more electric trucks to the roads, Daimler also announced the opening of the Automated Truck R&D Center in Portland. But don't expect the first electrified semis to have anything other than the semi-autonomous features already found on other vehicles in the Daimler lineup.

"We don't believe in level-five trucks. I don't think we're ready for that," Nielsen said. "One day you'll see a highly automated electrified vehicle."

Like the rest of the evolution of transportation, none of this will happen overnight. Daimler wants to make sure it's there when it does. For now, at least, it's focusing on putting a lot of big vehicles on the road that doesn't pump out huge clouds of smog.

The FCC has been willing to tackle surprise phone bill charges for a long time, but now it's more explicitly forbidding the practice. The regulator has approved rules that include a "clear ban" on cramming, or slapping customers with unauthorized charges on phone bills. The activity was already illegal, the FCC said -- this mainly "reaffirms" the agency's authority to crack down on bad behavior.

There are also new rules clamping down on slamming, or switching a customer's phone company through deceptive means. If a company misleads you during a sale call, that fibbing will "invalidate" any permission you gave, the FCC said. Moreover, any phone companies that abuse third-party verification for switches will lose that process for five years and have to use alternative methods. In other words, a company that regularly tries tricking people into changing networks could find itself at a disadvantage.

This being the deregulation-happy Pai-era FCC, there are some looser rules, too. The Commission has eliminated a requirement that phone companies using third-party verification have to get your permission for every service being sold. It's a "time-consuming" demand that can "confuse" customers, according to the regulatory body. There's a degree of truth to that, but it does increase the chances that you might unwittingly greenlight a service.

Facebook hasn't been shy about its plans to challenge game streaming services like Twitch, Mixer and YouTube Gaming, and it's taking that effort to its next logical step. The social site recently started testing a dedicated gaming video portal (appropriately shortened to fb.gg) that highlights both live and pre-recorded footage based on the games, creators, pages and groups you follow. It'll also put the spotlight on eSports competitions and game-related events, and mobile gamers will see a section for Instant Games. The experience will no doubt seem familiar if you've used rival services, but it's hard to complain when you can find a Fortnite stream that much faster.

At the same time, Facebook is giving new streamers more opportunities to find their footing. It's unveiling a Level Up program in the months ahead that will let newcomers earn money from viewers who buy and send virtual items in the middle of live streams. It's somewhat like Twitch's Affiliate tier -- you can still generate an income without a full-fledged partnership. On that note, Facebook said it plans to expand its creator subscription test to include more partners in the weeks ahead.

There's a clear goal behind the two moves: Facebook is hoping to turn its game streaming into more of a viable option with better exposure and money-making opportunities. It's still a long way off from attracting a host of superstar broadcasters like Ninja, but it might have a larger influence going forward.

Latest Technology / GM is supplying next-gen batteries for Honda EVs
« on: June 09, 2018, 10:56:18 AM »
GM has expanded its collaboration with Honda to supply the Japanese automaker with next-generation batteries. These will go in EVs built mainly for the North American market, and though neither company stated when they would start using the new power options, sources told Reuters that they're expected to begin production in 2021.

GM's innovations intend to cut electric battery costs in half -- which is huge, given their typical pricetag between $10,000 and $12,000, sources told Reuters earlier in the year. The deal will help Honda speed up EV production after 2020. It's not the automaker's first collaboration with GM: In early 2017, the pair went in together on a Michigan factory dedicated to producing hydrogen fuel cells to power their vehicles. But given the auto industry's increasingly expansive investments in electric vehicles -- GM included -- this is a savvy move to get more EVs on the road.

The Insider program on Xbox One is a few years old now and just keeps rolling out new features for testing by early adopters. Now Microsoft has announced that it's giving participants a chance to try features that are even further away from their scheduled release date with a new "Alpha - Skip Ahead" ring of testers.

There's no word on exactly which features people will be able to test, but there's traditionally one or two new items coming in a Winter-window update, and isn't there some kind of event just around the corner where Microsoft might make such an announcement? If you value life on the bleeding edge over stability -- or just have multiple consoles and can afford to have one that's running far-future test builds -- you will see the option to enroll "in the coming weeks" if you're an Alpha tester already, and later by invitation for others.

Despite rumors it's up for sale, Essential is still operating as if everything is just fine. After releasing a new beta for Android P, the company has just launched its second modular accessory. The Audio Adapter HD packs a pre-amp and an ESS Sabre DAC that can handle high-resolution MQA (master quality audio) used by Tidal and other services. More importantly for most Essential PH-1 smartphone owners, it has a 3.5mm headphone jack, so they can soon dust off their favorite cans or earbuds.

Essential, launched by Android founder Andy Rubin, is also offering a free three-month Tidal HiFi subscription to all Essential phone owners, so that they'll have something to play using the audio adapter. Tidal HiFi has over 50,000 tracks encoded with MQA, which "allows subscribers to hear music just as it was recorded in the studio; an audio experience as the artist intended," as Tidal describes it.

Essential's PH-1 was marketed from the get-go as a modular smartphone, so the unveiling of a second module is obviously a big deal. The Audio Adapter HD is set to arrive sometime this summer, but the price has yet to be announced. Essential's first accessory, a 360-degree camera, retails for $200, but can be found on Amazon for $76 at the moment. The phone itself, the first with a camera notch (yes, ahead of the iPhone X), has dropped in price from $700 to $499.

In The Netherlands, a company called Van Wijnen is working with the city of Eindhoven to build the world's first community of 3D-printed houses. The planned community will have five houses, all printed with concrete. Each subsequent house will build on the ones that came before; the first house will be relatively simple, just one story. The fifth house will be two stories and incorporate what the team has previously learned.

At the beginning, the houses will be printed offsite and brought to their final location in the Meerhoven district of Eindhoven. The aim is to make the futuristic-looking houses a work of art in and of themselves, so the final community looks like a sort of sculpture garden.

Van Wijnen is embarking on this project for multiple reasons. According to The Guardian, there are a shortage of bricklayers in The Netherlands. The craft is becoming more expensive as a result. In contrast, concrete is relatively in expensive and versatile. What's more, 3D printing it is economical because none of the material goes to waste, and the method allows printing different types of concrete (reinforced with insulation or coated with dirt repellant) at once. Additionally, it can be easily customized according to the wishes of the person who will live in the home.

The real key here is that these homes aren't just models; they will actually be lived in. And if this project is successful, more 3D-printed concrete homes will follow. The first home of Project Milestone should be ready sometime in 2019. For now, the homes are being printed offsite, but the company hopes that by the fifth house, the work will be done at the Meerhoven site. And apparently, the waiting list for the first house is already 20 people long, so it's clear that Van Wijnen won't have trouble finding someone to rent their 3D printed homes.

Latest Technology / The best portable air conditioner
« on: June 09, 2018, 10:53:48 AM »
This post was done in partnership with Wirecutter. When readers choose to buy Wirecutter's independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here.

After putting in 65 hours of research, comparing more than 110 portable air conditioners and testing 11 of the best models, we recommend the Whynter Elite ARC-122DS. However, bear in mind that because portable air conditioners are housed entirely indoors they're extremely inefficient, and in very hot weather they can struggle to do the job at all. Dual-hose models like the Whynter are more efficient and effective than single-hose models. But, if possible, you should use a window or wall AC instead—they work better, usually cost less, and don't take up as much space.

While the Whynter Elite ARC-122DS is our top pick, we have seen this model and others experience stock issues. If you're willing to wait a bit longer, it is available for purchase on backorder.

Why don't portable ACs work well?
Air conditioning works by moving heat from the inside to the outside of your house. Most types of air conditioners are designed to sit at least partially outdoors, where the heat can just passively radiate away. But a portable AC sits entirely indoors, so it needs to actively push the heat up an exhaust hose that ventilates through a window (sort of like a clothes dryer). It's quite an uphill battle.

This design has several bad side effects. The worst is that it pulls warm air into the room through cracks around doors, windows, and floorboards. Another side effect is that a portable AC's exhaust system wastes a bunch of cold air. Other types of ACs keep indoor and outdoor air almost totally separate: Indoor air gets cooled as it passes over the evaporator, outdoor air takes the heat off the condenser. But a portable AC uses some indoor air—which it already took the time and energy to cool off—to take heat off the condenser, and then dumps it outside.

Finally, the body and hoses radiate some heat back into the room before it all gets pushed out through the exhaust. The Department of Energy determined that, on average, a portable AC's hoses radiate about 3 Btu per square foot, while the body casing radiates enough heat to offset about 2 percent of cooling.

We considered both single- and dual-hose models, but gave a preference to the latter. With such a huge field of contenders, we decided to focus on models with a high energy-efficiency ratio, eliminating most with an EER below 9.0.

We then homed in on models with the strongest owner ratings, because good ratings usually indicate good reliability. A fair price for a portable AC with these features is somewhere in the range of $325 to $400 for single-hose, and $400 to $500 for dual-hose.

For our most recent tests we settled on eight finalists (five single-hose and three dual-hose) that were priced fairly and widely available at the time of our research, purchased them, and brought them in for testing: the Honeywell MN10CESWW, Honeywell HL10CES, Whynter ARC-12S, Black+Decker BPACT12WT, LG LP1217GSR, Haier HPND14XCT, Whynter ARC-14S, and Whynter Elite ARC-122DS. (We did not test the Elite ARC-122DHP—the version with the heater and drain pump—because its other components are identical to the ARC-122DS, according to Whynter.)

In the four years we've covered portable air conditioners, we've tested temperature, noise, humidity, airflow, efficiency, and portability. But in that time we haven't gotten any closer to developing a system that can reliably and consistently measure the cooling performance of a given model. This is an unusually difficult category for testing, and even the Department of Energy acknowledges in its 122-page Final Rule that there are simply too many variables influencing how well an AC performs.

That said, we did find a way to measure how much infiltration air a machine is likely to draw into a room. We used a handheld anemometer to get a basic air velocity rate (in feet per minute), then multiplied that figure by the duct area (in square feet), and weighted the results (as described here) to arrive at a general infiltration airflow measurement in cubic feet per minute.

To test noise, on the advice of audiovisual expert and Wirecutter contributor Geoff Morrison we connected a calibrated microphone to an iPhone 7, launched the SPLnFFT Noise Meter app, and set it to a C-weighting with a slow response.

We also hooked up each unit to a Kill A Watt electricity-usage meter to gauge the advertised energy use against the real-world figures. Finally, we did livability tests. We hauled the units around an apartment, comparing the maneuverability of the casters and how smoothly they rolled over thresholds and carpeting.

If you need a portable air conditioner, we recommend the Whynter Elite ARC-122DS, a dual-hose unit. It's quiet for a dual-hose machine, and drew the least amount of infiltration air of any model we tested.

The Elite ARC-122DS has the best specs of any portable AC we've come across. It's a dual-hose model, with a category-leading energy efficiency ratio of 12.0, and a strong 12,000 Btu cooling capacity. As hard as it is for us to objectively measure performance, we did get a chance to try out the ARC-122DS on a 90 °F day—it made the room feel comfortable, for whatever that's worth.

In our 2018 tests the ARC-122DS produced some of the quietest decibel figures of any AC. The compressor, which initiates the cooling cycle, is by far the loudest part of any air conditioner. The ARC-122DS is noticeably more compact than its closest competitors, and much lighter, too.

In other aspects, the ARC-122DS is typical of dual-hose models. It comes with the same installation kit as our other finalists. The control scheme and remote control are also pretty much the same—no real complaints to note. Testing the same unit for the second year in a row, we didn't find any reliability problems; it worked just as well and showed no signs of wear and tear, even after carrying it up a flight of stairs, throwing it in the back of a car, and moving it to a different home on the other side of Boston.

Runner-up: Whynter Elite ARC-122DHP
The Whynter Elite ARC-122DHP is the same air conditioner as our main pick, with the addition of a heater and a drain pump. That means it can double as a space heater during cold weather, and automatically pump water out of the condensation tray, instead of needing manual emptying.

Also great: Haier HPND14XCT

If our main picks are unavailable, or their prices jump, the Haier HPND14XCT is a good alternative. It's got a higher cooling capacity (14,000 Btu) than our top picks, and in our testing it drew in the second-least infiltration air, meaning you can expect it to work quickly and efficiently. It's also the single quietest dual-hose AC we tested in 2018.

A good single-hose portable air conditioner: Honeywell HL10CES
If you're not super-concerned with performance during a heat wave, and just need something to take the edge off at night or in a small, overly warm apartment, the Honeywell HL10CES is a good option. It has one of the highest efficiency ratings we've seen, and it produced the single quietest operation of any AC we tested this year.

Latest Technology / Yahoo Messenger will shut down on July 17th
« on: June 09, 2018, 10:52:20 AM »
Yahoo announced that its Messenger service will be discontinued after July 17th, 2018. If you're looking for a Messenger replacement, Yahoo recommends the product Squirrel, which is currently in beta and invite only. You can request an invitation here.

You can download your chat history for the next 6 months at this download request site. Your chats will be emailed to you. If you have anything you want to save from Yahoo Messenger, it's a good idea to get a copy, because users will be unable to sign into the service after July 17th.

It's not the first long-standing chat app to shut down -- AOL Instant Messenger shut down December 15th of last year. But Yahoo Messenger was one of the few old-school messaging services left. "We know we have many loyal fans who have used Yahoo Messenger since its beginning as one of the first chat apps of its kind," the company said in an FAQ. "As the communications landscape continues to change over, we're focusing on building and introducing new, exciting communications tools that better fit consumer needs."

Researchers at MIT have found a way to stump hackers who are trying to snag data from wireless signals. They've created a transmitter that moves data packets between different radio frequencies rapidly enough to keep hackers at bay.

Typically, this method, known as frequency hopping, sends each data packet over a random radio channel. These packets often contain thousands of bits, and larger packets move just sluggishly enough to let hackers intercept them. The MIT transmitter, however, goes a step further; it bounces each individual bit at random every microsecond across 80 different channels, which is too fast and low-level for hackers to keep up with. The researchers also developed a different type of wireless protocol (i.e. a new type of WiFi or Bluetooth) to support the rapid frequency hopping.

The receiving device needs to understand how data is being sent to it, so the sending device shares a key before transmitting the bits. The receiving device can then make sense of how the data is being split and stitch it together, but any potential hackers won't -- so for them, trying to fish the data out of the air and make sense of it is nigh-on impossible. The scientists are presenting a paper on the transmitter at the IEEE Radio Frequency Integrated Circuits Symposium, which starts this weekend.

As the number and types of connected devices expands rapidly, it's becoming even more important to secure the data they're transmitting. The researchers noted that their transmitter could protect medical devices like pacemakers and insulin pumps from attacks, for instance. The technology could also "secure smart meters that read home utilities, control heating, or monitor the grid." Given that hackers have attacked power grids and other public resources, this could be an important development in shutting them out. News of the transmitter follows other recent MIT work on wireless data, like a way to give drones and self-driving cars the most current possible information.

While swipe gestures to deal with your email have been around for some time, Gmail for Android just made them even better. If you're running the latest version of the Gmail app (8.5.20) on your phone, you'll now be able to customize the swipe actions instead of just use the default settings. We've confirmed the new functionality, which was originally spotted by Android Police and reported by 9to5Google.

ou can enable the new Swipe actions feature in Gmail's General settings screen, then tap through to the specific Swipe actions page. You'll then be able to choose what happens when you right or left swipe, including Archive, Delete, Mark as read or unread, Move to, Snooze or None. This brings the Gmail app (on Android, at least) up to par with Gmail's web mail's ability to snooze your emails until later.

Once you reconfigure your swipe action, it should work across the entirety of the Gmail app. Now you're in charge of what happens when you swipe on an email. According to Android Police, the update has been rolling out over the past week, so you should see it soon if you don't already.

The Department of Energy pulled back the curtain on the world's most powerful supercomputer Friday. When Summit is operating at max capacity, it can run at 200 petaflops -- that's 200 quadrillion calculations per second. That smokes the previous record holder, China's Sunway TaihuLight (which has a 93 petaflop capacity). Summit is also about seven times faster than Titan, the previous US record holder which is housed at the same Oak Ridge National Lab in Tennessee. For perspective, in one hour, Summit can solve a problem that it would take a desktop computer 30 years to crack.

Summit's 4,608 servers, which take up the size of two tennis courts, house more than 9,000 22-core IBM Power9 processors and more than 27,000 NVIDIA Tesla V100 GPUs. Cooling the system takes 4,000 gallons of water a minute and Summit uses enough power to run 8,100 homes.

There's a lot more to Summit than simply snatching back a record China's held for five years. It was designed for artificial intelligence operations, and can use machine learning and deep learning to power research into health, physics and climate modeling, among other domains.

Scientists have already used Summit to run what they say is the first exascale scientific calculation. That's one billion billion calculations per second (or one exaop). Summit almost doubled that, as it ran at 1.88 exaops to analyze millions of genomes; the supercomputer can hit 3.3 exaops using mixed precision calculations. The US is aiming to build a fully capable exascale computing ecosystem for research by 2021, and Summit is a step towards that.

Upcoming projects include analyzing exploding stars (or supernovas) to find out how elements like gold moved through the universe, and running simulations on new types of materials such as superconductors. Scientists also plan to look for relationships between cancer factors like genes, biological markers and environment by crunching vast reams of health data. Researchers will use Summit's power to probe other disease markers, such as for Alzheimer's, heart disease and addiction. "Summit is enabling a whole new range of science that was simply not possible before it arrived," Oak Ridge computational biologist Dan Jacobson said in a release.

There's a battle between not only the US and China, but Europe, Japan and other nations to build better supercomputers. The machines aren't just focused on health and environmental research; supercomputers are used for aircraft design and developing nuclear weapons too, so there's a lot at stake.
