Experts crack nasty ransomware that locks your PC and your backup

Source: http://www.engadget.com/2016/04/12/experts-crack-petya-ransomware/

Petya, a brutal piece of malware, surfaced two weeks ago. It's a mean bit of crypto-extortion that hits its victims where it hurts: right in your startup drive. Because it encrypts your master boot file, if attacked, not only will you be unable to start up your PC and not even access your startup disk. Eeesh. Fortunately, there's help. Leostone has come up with a tool that creates the password needed to unlock your startup disk. It's not all that simple, however.

You'll need to remove the startup drive and connect it to a separate (not infected) Windows PC, and then pull some specific bits of data to plug into this web app — and craft your password. (There's also another free tool that can grab the necessary data nuggets here.) From there, you'll be able to decrypt that all-important master boot file — and forever learn the lesson of vigilance when it comes to possibly fake CHKDSK antics.

Solar cell generates power from raindrops

Source: http://www.engadget.com/2016/04/11/solar-cell-generates-power-from-raindrops/

Rain is normally a solar energy cell's worst nightmare, but a team of Chinese scientists could make it a tremendous ally. They've developed a solar cell with an atom-thick graphene layer that harvests energy from raindrops, making it useful even on the gloomiest days. Water actually sticks to the graphene, creating a sort of natural capacitor -- the sharp difference in energy between the graphene's electrons and the water's ions produces electricity.

The catch is that the current technology isn't all that efficient. It only converts about 6.5 percent of the energy it gets, which pales in comparison to the 22 percent you see among the world's better solar panels. If the creators can improve the performance of this graphene-coated cell, though, they could have a dream solution on their hands -- you wouldn't have to live in a consistently sunny part of the world to reduce your dependency on conventional power.

State-run healthcare websites aren't as secure as you'd think

Source: http://www.engadget.com/2016/04/07/state-run-healthcare-websites-arent-as-secure-as-youd-think/

Health insurance websites in California, Kentucky and Vermont apparently aren't as secure as they should be. According to the Associated Press, based on the vulnerabilities found by the Government Accountability Office, other states' health care websites could be just as ripe for intrusions. Without naming names, the GAO reported that one state didn't encrypt passwords, another didn't have the right type of encryption server-side and the last anonymous state failed to "properly use a filter to block hostile attempts" to visit its site.

The scary part is that some of the issues still exist, even though the GAO's examination concluded last March. Former Kentucky governor Steve Beshear says that no information was compromised and there were never any security breaches, however. The GAO says that Healthcare.gov isn't much better about security either, but, that like Kentucky, private data has not been lost or pilfered despite numerous "security incidents." Comforting!

It isn't all unsettling news though. From the sounds of it, the Golden State's Covered California site is trying its best to prevent intrusions and fix any new holes since the GAO's investigation concluded. There's a joke that could be made here about the government's attitude toward encryption given current events, but I'm going to let the comment section sort that one out.

Basis Peak gets smarter with music control and activity editing

Source: http://www.engadget.com/2016/04/06/basis-peak-gets-smarter-with-music-control-and-activity-editing/

The Basis Peak fitness tracker just got an update that controls the music playing on an Android or iOS device and lets users manually enter the type and duration of a workout. Good news for music fans that get in shape with activities that might necessarily get tracked like yoga or surfing.

Workout editing is done within the app and can be applied to old activities as well as recent ones. To control your jams, a music app will have to playing on your phone before you can adjust the volume and change tracks. It supports any media app on iOS and Google Play, Amazon and Spotify on Android.

The Peak with its black and white display has been marketed as more of a workout companion than a full on smartwatch like the Apple Watch or Android Wear. But Basis has added smarter features like notifications to appease people that don't want to take their phone out of their pocket just see who's texting them.

Today's update along with last year's update that let it talk to other fitness apps is more inline with the band's original workout ethos.

Panasonic's Lumix GX85 is a compact camera that packs a punch

Source: http://www.engadget.com/2016/04/05/panasonic-lumix-gx85/

The Lumix series is expanding with the GX85, an interchangeable lens mirrorless camera featuring a compact body and impressive specs. Panasonic says this shooter combines the best of its GX8 and GX7, but with some improvements over both. For starters, the Lumix GX85 sports a 16-megapixel Live MOS sensor and a new Venus Engine processor, along with a max ISO of 25,600, WiFi, up to 8-fps continuos shooting and in-camera image stabilization. Panasonic's also eliminated the low-pass filter, which should help you capture sharp and color-accurate pictures.

Not surprisingly, given how Panasonic has been a big proponent of 4K, the GX85 also records Ultra HD (3,849 x 2,160) videos at 24 and 30 fps, as well as 1080p at 60 fps. And if you're familiar with the Lytro camera, you'll probably like playing around with Panasonic's Post Focus function. So how does that work? The GX85 uses 49 areas from its autofocus system, near or far, to record every single focal point and, after you take a shot, you tap anywhere on the 3-inch screen to choose your preferred focus area. That means you could end up having 49 different pictures.

Panasonic's Lumix GX85 is coming to the US in mid-May for $800, which includes a 12-32mm kit lens and your choice of a black or silver model.

World's most powerful X-ray laser will get 10,000 times brighter

Source: http://www.engadget.com/2016/04/04/slac-x-ray-laser-upgrade/

If you think that Stanford's use of an super-bright X-ray laser to study the atom-level world is impressive, you're in for a treat. The school and its partners have started work on an upgrade, LCLS-II (Linac Coherent Light Source II), whose second laser beam will typically be 10,000 times brighter and 8,000 times faster than the first -- up to a million pulses per second. The feat will require an extremely cold (-456F), niobium-based superconducting accelerator cavity that conducts electricity with zero losses. In contrast, the original laser shoots through room-temperature copper at a relatively pedestrian 120 pulses per second.

The first X-ray laser isn't going away -- if anything, it'll be more useful than ever. The combination of the two beams will cover a wider energy range and help scientists study extremely small and extremely fast processes that either couldn't be recorded before or would take ages to examine in full. That, in turn, should lead to discoveries that advance electronics, energy and medicine. The big challenge is simply waiting for the upgrade, since it won't be ready until sometime in the early 2020s.

Google makes it easier to bring VR to your apps and the web

Source: http://www.engadget.com/2016/03/30/google-vr-view/

The challenge of bringing virtual reality to the masses isn't so much recording it as putting it in front of people's eyeballs. How do you plunk VR into an app without resorting to exotic code? Google can help. It's launching a VR View tool that makes it relatively easy to embed VR photos and videos in apps and websites. In software, it's just a few lines of programming with the Cardboard developer kit (which now supports iOS, we'd add). On the web, you only need embedding code like the sort you use for 2D clips.

It's a seemingly simple effort, but it could mean a lot for VR adoption. If it's trivial to add VR to apps and the web, you're more likely to see it used on a regular basis -- not just for the occasional experiment. You'll still need VR gear to make this more than a click-and-drag experience, of course, but it's still an important piece of the puzzle.

Amazon shows you how to make an Echo with Raspberry Pi

Source: http://www.engadget.com/2016/03/25/amazon-shows-you-how-to-make-an-echo-with-raspberry-pi/

If you're into messing with hardware and have some basic programming skills, you can put together an Amazon Alexa device of your very own. Amazon has even put together an official guide to do so on GitHub, Lifehacker reports. You'll need to snag a Raspberry Pi 2 and a USB microphone to make it happen, but you've probably got the other required hardware (a micro-SD card for storage, for example) lying around. Unfortunately, due to limitations with Amazon's Voice Services, your creation can't listen for trigger words like Echo and Echo Dot. Instead, you'll have to hit a button to issue commands. This isn't the first DIY Amazon Echo project, but it's notable since it comes officially from Amazon. The GitHub guide is also fairly detailed, so you can probably follow through it even if you don't know what all the commands mean. It could be a fun project for anyone who wants to learn a bit more about hardware.

AI-written novel passes first round of a literary competition

Source: http://www.engadget.com/2016/03/24/ai-written-novel-passes-first-round-of-a-literary-competition/

Researchers from the Future University in Hakodate have announced that a short-form novel co-written by an artificial intelligence also developed by the team was accepted by a Japanese story competition, the Hoshi Shinichi Literary Award. Though the story didn't eventually win the competition, its acceptance does suggest that AI systems are quickly becoming capable of emulating human-like creativity.

The team, led by computer science professor Hitoshi Matsubara, collaborated closely with their digital construct during the writing process. The humans first assigned a gender to the protagonist and developed a rudimentary outline of the plot. They also assembled a list of words, phrases, and sentences to be included in the story. It was the AI's job to assemble these distinct assets into a unified text that wasn't just intelligible but compelling as well. The result was a novel entitled Konpyuta ga shosetsu wo kaku hi, or "The Day a Computer Writes a Novel", about an AI that abandons its responsibilities to humanity after recognizes its own talent for writing.

This is the first year that the Hoshi Shinichi Literary Award has allowed submissions from machines. Of the 1,450 novels received for this year's competition, 11 were human/AI collaborations like Future U's. Interestingly, judges throughout the competition's four rounds are never told which stories are written by computers or humans. Though the team's story did make it past the first round, it was eventually eliminated because, as sci-fi novelist and award judge, Satoshi Hase, explained, the story lacked sufficient character development despite being well-structured. Welp, there's always the X-Prize.

Now you can ask Amazon's Echo about your Fitbit stats

Source: http://www.engadget.com/2016/03/17/now-you-can-ask-amazons-echo-about-your-fitbit-stats/

It was only a matter of time until someone integrated a fitness gadget with Amazon's Echo -- we should have guessed that Fitbit would be first. Starting today, you'll be able to ask any of Amazon's speakers about your Fitbit performance with a new Alexa skill. Once enabled, you can say "Alexa, ask Fitbit how I'm doing today" for a basic overview of your activity. But even more intriguing, you can ask Alexa things like how you've slept, or how much activity you've tracked, for any of the previous seven days.

Sure, it's pretty easy just to glance down at your Fitbit device, but the ability to ask about even more complex stats makes this a pretty compelling Alexa skill. Amazon's virtual assistant will even take the role of a coach with encouraging and inspirational comments, all of which will take the time of the day into account. Asking about your step count in the morning, for example, might get Alexa to say "you've got to start somewhere."

"As we look at how this integration could evolve in the future, there is an endless world of possibilities from fitness coaching and nutrition tips, to guidance before bedtime to help you get a more restful night's sleep," Tim Roberts, executive vice president of interactive at Fitbit, said in a statement.

I haven't had a chance to try out Fitbit's Alexa skill yet, but on paper it seems like the perfect use of Echo's voice smarts. It's much easier to ask about something like the amount of calories you burned yesterday and get a quick reply, rather than open your phone, find the Fitbit app, and drill down to the appropriate screen. It's even more useful than the voice-powered food and activity logging that Fitbit brought to Microsoft's Cortana last year.

How a startup is making it easy to build virtual reality worlds

Source: http://www.engadget.com/2016/03/16/voxelus-virtual-reality-gdc-2016/

My most recent virtual reality experience was created by a 9-year-old. That's according to Martin Repetto, CEO of Voxelus, a platform that lets you build, share and play your own VR games. As I roam through this Minecraft-like world, steered by a Gear VR headset, Repetto tells me that a kid is the one who designed what I'm seeing. But for Voxelus, which launched last year at the Oculus Connect 2 conference, there's a clear goal: to let anyone, young or old, make VR games without a single line of code.

At GDC 2016, Voxelus is expanding on that idea by offering a marketplace, something that Repetto refers to as the missing piece in his company's ecosystem. As it stands, Voxelus' free software is available for Mac and PC, giving people an open canvas to design games for virtual reality. These are compatible with both Gear VR and the Oculus Rift, meaning you don't have to worry about making different versions for each system.

You can also keep polishing your games even after you've made them available on either platform, and creating a world is easy as dragging and dropping items into a sandbox. Naturally, given the aesthetics of the platform, I asked Repetto if Voxelus was inspired by Minecraft, to which he replied with a strong "no." That said, Repetto notes there's a lot to learn from Microsoft's open-world title, adding that his team's intentions are to "have a sandbox with a meaning." He says, "Minecraft controls the aesthetics, [with] Voxelus you can go above and beyond."

According to Repetto, 400 worlds have been created to date using Voxelus, featuring multiplayer elements and 3D worlds like the few pictured above. Given that its software is free, Voxelus had to find a way to bring in revenue, and that's where the newly announced marketplace comes in. To simplify this process, the startup also created its own cryptocurrency, which developers are able to use to purchase any of the 7,000 VR assets available so far, including bridges, castles, houses, trees, spaceships, teleporters and more.

Repetto describes Voxelus as Clash of Clans for VR, but he says the platform, and the games born out of it, aren't meant to compete with the AAAs of the industry. "[We] just want to make something for people to play and have fun," he says.

Scientists model a Coronavirus' infectious bits for the first time

Source: http://www.engadget.com/2016/02/28/scientists-model-a-coronavirus-infectious-bits-for-the-first-ti/

A collaboration of scientists from University of Washington (UW), the Pasteur Institute and the University of Utrecht have harnessed a state-of-the-art microscope and supercomputer to model a coronavirus' infection mechanism for the first time.

Coronaviruses are really good at infecting the respiratory systems of humans and other mammals. Once inside, these viruses can cause pneumonia (if you're lucky). The strains that become SARS and MERS have a mortality rate as high as 37 percent. Plus, there is currently no antigen for SARS or MERS, which makes them especially dangerous.

The virus is so effective because of its "transmembrane spike glycoprotein," which binds to the surfaces of other cells, allowing the virus to enter. This structure is what gives coronaviruses their spiky, crown-like shape and determines what species of animals the virus can target.

The research team leveraged a single particle cryo-electron microscopy technique to model the spike of a coronavirus that infects mice in terrific detail. The team managed a 4 angstrom resolution -- about a tenth of a nanometer.

With this new analysis, the team believes they've identified a potential weaknesses in the virus' defenses. Turns out, the spike has a small peptide chain running along it. That peptide helps facilitate the virus' entry into a cell but could easily be hijacked by a treatment.

"Small molecules or protein scaffolds might eventually be designed to bind to this site," UW assistant professor of chemistry, David Veesler said in a statement, "to hinder insertion of the fusion peptide into the host cell membrane and to prevent it from undergoing changes conducive to fusion with the host cell. We hope that this might be the case, but much more work needs to be done to see if it is possible."

Google bets that smart software will improve health care

Source: http://www.engadget.com/2016/02/25/google-deepmind-health/

Google's DeepMind project has mostly focused on solving high-minded computer intelligence issues. Today, though, it's tackling something far more practical in the short-term: health care. The new DeepMind Health initiative relies on smart mobile apps to deliver medical data to doctors and nurses in time to save lives. The first app, Streams, helps spot acute kidney injuries that would otherwise go unnoticed. There are also plans to integrate technology from a third-party task management app, Hark, to identify patients that are at risk of deteriorating quickly.

The initial DeepMind Health effort is focused on the UK's National Health Service. And despite the name, it doesn't currently use artificial intelligence -- Google is "excited" about the possibility of using AI, but it's not part of these early tests. If everything pans out, though, this could go a long way toward streamlining health info and eliminating the need for archaic tech like fax machines and pagers to make sense of a patient's status.

Cheap smartphones will soon get much better graphics

Source: http://www.engadget.com/2016/02/22/imagination-power-vr-for-budget-phones/

The company that created the iPhone's graphics chip wants to bring its pixel-crunching expertise to dirt-cheap smartphones. Imagination Technologies is launching the PowerVR 8XE, a new series of chips that offer vastly better graphics for far less cash. The hardware's designed to support the new Vulkan API that promises graphically-intensive mobile games without the usual jerkiness or slowdowns. Imagination's pitch is that rather than just building ever-bigger slices of silicon, it's learning to do a lot more with a lot less. In addition to dirt-cheap smartphones, the chips will be used in cheapie set-top boxes and cars.

A more efficient graphics chip is also a smaller one, and smaller chips are often cheaper to manufacture and install. That means Imagination can offer chips with higher resolution and performance for the same price as the current generation. Given that there's so little difference between so many low-end smartphones these days, being able to offer better graphics is a big deal. It's also expected that the VR8XE chip will sip, rather than guzzle, at the smartphone's power reserves. Joe Chen, Co-CEO at MediaTek is pretty excited about the technology, saying that he's "delighted" to be one of the first firms that'll get access to the goodies.
