Skype 6.0 brings revamped design to both iOS and Android

Skype users have ridden a rollercoaster of different designs over the years, and the latest version promises yet more change. Version 6.0 has been completely redesigned for both iOS and Android apps, which are now in lockstep with each other. For Google’s ecosystem, the new layout took a page from the Android 5 “Material” playbook with circular icons and other touches. Other features include a floating action button to start new calls or chats (à la Facebook’s Messenger), enhanced search and improved messaging. There are also custom ringtones, photo sharing and web link reviews to bring the app in line with rival messaging products like Google’s Hangouts. On the Apple side, Microsoft made similar visual tweaks and added swipe gestures for calls and messages. It’s also easier to post photos, links and emoticons when you’re on a video or voice call. Other tweaks include enhanced search, location info and other features you’d expect on a messaging system. The Skype iPad app has been completely revamped to take advantage of the larger screen, and now includes group calling to boot. Both the Android and iOS apps are now available, and as for Skype on Windows 10 Mobile, MIcrosoft said it’s working hard on the next version and “we’ll let you know when we have more to share.” Filed under: Cellphones , Tablets , Mobile , Microsoft Comments Source: Skype Tags: Android, iOS, iPhone, microsoft, mobilepostcross, Skype, Skype 6.0

Just add water and this squid-inspired plastic heals itself

While you’ve been busy scarfing down fried calamari rings, scientists at the University of Pennsylvania have been doing something else with squid . Namely? Studying the cephalopod’s ring teeth for a way to create a material that heals when water’s present , much in the way that those tentacle-bound choppers do. The way the report spotted by Popular Science tells it, the researchers were able to reproduce the type of proteins found in the self-healing squid teeth and trigger bacteria to make it in a lab environment. To test just how strong the new material was, the scientists formed the protein into the shape of a dog bone and cut it in two with a razor blade. After pressing the two segments back together, dousing them with a bit of water and applying pressure, the pieces fused and were still as strong compared to before they were cut. Like PopSci notes, this type of material could be used to coat things deep-sea internet cables or perhaps help biomedical devices have a longer lifespan, but is still a ways off from primetime. That and it still needs to be tested against shark bites , of course.

Samsung jumps into Ultra HD Blu-ray, as Fox provides the movies

Today Samsung is the first company to announce an Ultra HD Blu-ray player, taking the lead in 4K and HDR video. Following up on its big Ultra HD push at CES and the movie streaming/ download tech that has arrived in the months since, Samsung is ready to push super high resolution movies (four times the resolution of Blu-ray, and 64 times as many colors) on discs too. There’s not much detail available on its new player, although we expect it will cost less than the $1, 000 price its first Blu-ray player commanded nearly a decade ago and it should launch early next year. Joining the tech company on its IFA 2015 stage are Fox execs, with president Mike Dunn proclaiming the studio is committed to releasing its slate of upcoming movies in Ultra HD with HDR day-and-date with the Blu-ray and Digital HD releases. That includes Fantastic Four , Maze Runner , Kingsman: The Secret Service and more. Samsung’s Ultra HD Blu-ray player is curved to match its TVs , and also includes a number of UHD streaming services. The other news today at IFA is that Samsung’s TVs will be the first ones getting a software update to support HDMI 2.0a , necessary to receive HDR info from the new Blu-ray players. As far as that UHD Alliance the tech industry and Hollywood are creating to push their new video standards, Fox CTO Hanno Basse said it has tripled in size, and hopes to share more details in “the coming months.” Filed under: Home Entertainment , HD , Samsung , Microsoft Comments Tags: 4K, Blu-ray, Fox, hdpostcross, HDR, IFA, IFA2015, microsoft, MikeDunn, samsung, SUHD, UltraHD, UltraHDBlu-ray

Mac keychain flaw can send your passwords to hackers via text

Antoine Vincent Jebara and Raja Rahbani have discovered a Mac Keychain vulnerability that hackers can easily exploit to steal passwords, certificates, etc. with very little user interaction needed. The duo stumbled upon the flaw while working on the Keychain for their identity management software Myki . They found out that attackers can craft commands that can make Mac’s password management system prompt users to click an “Allow button” instead of asking them to type in their passwords. Once a user clicks that button, the malicious code can forward Keychain’s contents via text, though the info could also be saved somewhere for download later on. The malware required to trigger that process can be introduced into the victim’s computer via innocuous files such as images, documents and spreadsheets. In fact, the proof of concept Rahbani and Jebara developed to test out what they discovered launches the malware-wrapped image in Preview after you click Allow. They designed it that way to show how that method can be used to allay any suspicion brewing in the back of the victim’s mind. In Jebara’s email to Engadget , he said they already notified Apple of the vulnerability and are waiting to hear back. He explained that they decided to come out with this information, because it could be extremely harmful to users if exploited. By knowing the flaw’s nature, you can at least protect yourself by not click strange buttons that pop up in Keychain. We disclosed because we feel that it is the right thing to do knowing that a vulnerability of this magnitude would have disastrous consequences (you wouldn’t be able to open any third-party file on your computer without the risk of losing all of your sensitive information until Apple issues a patch)… The vulnerability is extremely critical as it allows anyone to steal all of your passwords remotely by simply downloading a file that doesn’t look malicious at all and that can’t be detected by malware detectors because it doesn’t behave the way malware usually does.

ASUS unveils the Intel-powered, Windows 10 VivoStick

Intel generated a storm of interest when it launched the HDMI-based Compute Stick , but is anybody willing to buy a tiny, under-powered PC? Who knows, but ASUS has just launched its own model that trumps Intel’s in nearly every way. It’s a lot less clunky-looking and one-ups Intel’s Atom CPU with a Cherry Trail model, while adding an extra USB 3.0 port and headphone jack for good measure. Otherwise, it has the same 2GB of RAM and 32GB storage, and works in the same way: you plug it into any HDMI TV, add a keyboard and mouse, then compute away on Windows 10. At least, we hope so. As we noted in our review , Intel’s stick is far from a powerhouse and not quite up to its primary task of serving music and video streaming to your TV and sound system. However, at $129, the ASUS VivoStick runs a bit less than Intel’s $150 Compute Stick, which might make it worth the gamble. Availability has yet to be determined.

Google is working to make 4K video less of a data hog

Ultra HD 4K video is still in its infancy, but there’s no doubt the format will become increasingly popular in the next year or two. Huge players like YouTube and Netflix already support it, but delivering such high bandwidth video content remains a challenge. Google’s trying to do its part to solve that problem by developing a more efficient video compression codec called VP10. The new codec has been in the works for nearly a year, but the company gave some details about how effective it can be over the VP9 format it’ll eventually replace. In an interview with CNET , Google product manager James Bankoski said that VP9 uses half the bandwidth needed to deliver the same quality video as the popular H.264 format — and with VP10, the company is trying to cut it in half again. Reduced bandwidth usage isn’t the only thing VP10 has going for it — it should also provide shaper images, better color, and a better dynamic range between lights and dark. But despite some strong technical credentials and the backing of Google, widespread adoption of VP10 is hardly a foregone conclusion. H.264 is still the dominant video compression standard, and its successor (HEVC / H.265) will likely see widespread support. Still, this is a battle that isn’t yet won, and the dominance of YouTube means that VP10 will have a fighting chance against HEVC. The fact that VP10 is open source is another point in its favor; the licensing for HEVC could add red tape and costs for developers and devices makers. It’ll be a while before this conflict comes to a head, however: Google said it hopes to hit its performance targets for VP10 by the end of next year.

Algorithm turns any picture into the work of a famous artist

A group of German researchers have created an algorithm that basically amounts to the most amazing Instagram filter ever conceived: a convolutional neural network that can convert any photograph into a work of fine art. The process takes an hour (sorry, it’s not actually coming to a smartphone near you), and the math behind it is horrendously complicated, but the results speak for themselves. The algorithm leverages how complex neural networks process object recognition to help it rebuild photographs in the style of specific artists. On a very basic level, the network treats the art style of a source image as a “texture, ” and filters the target image through several layers of computational units to create a representation of it that agrees with the features of the original art. It’s a pretty neat trick, but not the actual point of the group’s research — the art project is simply an example that shows that convolutional neural networks are now capable of separating the content and style of an image. That said, researchers admit that content and style have to be careful balanced if the output image is to make any sense — too much focus on style, and the output image won’t look anything like the original photograph. The group plans to publish an additional paper on the algorithm in Nature later this year — but you can read the original report at the source link below.

Colombia is conducting widescale illegal surveillance

Want to know why it’s important to have checks on mass surveillance programs? Colombia should serve as a good example. Privacy International reports that the country not only collects bulk internet and phone data on a grand scale, but violates the law in the process — it’s supposed to require judicial approval for any surveillance, but regularly ignores that oversight. Colombian agencies have also relied on controversial tools like IMSI catchers (which scoop up nearby cellphone data) and Hacking Team’s spyware, and they’ve sought to expand their powers rather than rein things in. It’s no secret that Colombia has a history of surveillance, fueled in no small part by its decades-long battles with rebels and drug cartels. And unfortunately, the pressure to keep an eye on communications isn’t likely to drop anytime soon. A Venezuelan immigrant crackdown has forced many Colombia-born residents back to their homeland, increasing tensions between the two countries. It may take a long while before the political climate is truly conducive to surveillance reform.

Smoother movements help robots save a lot of energy

Eliminating the herky-jerky movements of robots isn’t just good for comforting nervous humans… it helps the robots, too. Researchers have developed smooth movement algorithms that slow the acceleration and deceleration of robots, saving as much as 40 percent of the energy they’d normally use. The trick is to order tasks in a way that lets robots move at their own pace without colliding into each other. Factory robots typically rush through tasks in a rigid order, only to wait for their fellow automatons to catch up. Here, they’re more flexible as to when and how quickly they get things done. You may see these more graceful robotics sooner than you think. General Motors is one of the partners in the project, and it has a vested interest in saving as much energy as it can. Robots use roughly half of the electricity at a vehicle assembly plant — if GM can save a lot of money using nothing more than code, you know it’s going to leap on that opportunity. While it’ll likely take a long time before robots ship with smoother movements from the get-go, it won’t be surprising if the underlying algorithms eventually become ubiquitous.

Ferrofluid ‘font’ produces trippy, one-of-a-kind art

You may have seen ferrofluid (aka magnetic ink) used for clever science demonstrations in school, but it might just get a much cooler application before long. Linden Gledhill and Craig Ward have developed Fe2O3 Glyphs , wild-looking characters created by putting a ferrofluid between glass plates and subjecting it to spinning magnetic fields. The result is a sort of anti-font — while the “letters” look like they could be part of an alien language, they’re so unique that you’d likely never produce the same effect twice. The creators are producing a digital typeface that you can use for your own projects, and they also hope to create a limited run of letterpress art prints to show your friends. You’ll need to pitch in to make both of these a reality, though. The duo has launched a crowdfunding campaign that gives you both the digital font and at least one print (either unique or copied). You’ll need to pledge at least $30 to get something in return, but it might be worth the cash if you’ve ever wanted science-influenced artwork in your home.
