Skype for Business is coming to your mobile device

Two months after Microsoft launched Skype’s Business edition , which integrates into MS Office Calendar and allows for group messaging/video chats/calls for up to 250 people, the video conferencing company announced on Tuesday that a mobile version for both iOS and Android devices is in the works. The mobile app will feature a central dashboard from which the user can search for contacts, check for and RSVP to upcoming meetings and dig through past archived conversations. Additionally, actually contacting people will be easier thanks to larger onscreen buttons and a full-screen video chat option. The apps aren’t ready quite yet though. Skype is currently recruiting businesses to participate in its preview program. Corporate IT managers can sign to eight employees (four for iOS, four for Android) up for the preview at www.skypepreview.com before August 17th. Once the apps actually go live “later this year, ” users will need to have Lync 2013 , on which this system is built, installed on their device in order to use them.

Your Android games are getting a software speed boost

iPhone users have low-level Metal code to speed up games and other visually intensive apps, but what if you’re an Android fan? Don’t worry, you’ll get your boost soon. Google has announced that Android will soon support Vulkan , an open graphics standard that cuts a lot of the computing overhead and gives apps more direct control over video hardware. It’s not as easy to work with as OpenGL, but it should let developers wring more performance out of your phone’s processor. That could prove very important when you’d otherwise struggle to run a game on a lower-end phone, or want to get pretty, high-detail graphics on a shiny new flagship . It’ll be a while before Vulkan for Android is ready — the standard itself isn’t available, let alone Google’s implementation of it — but it should be worth the wait if your Android devices double as game consoles .

Coder wins a thousand Twitter contests using a bot

You’ve probably seen “retweet to win” contests on Twitter, and maybe even won a t-shirt, concert tickets or marshmallows . But computer engineer Hunter Scott completely automated the idea and created a bot that entered every Twitter contest it could find — 165, 000 in total. As a result, he claims to have won four contests a day for nine months, for a total haul of over a thousand prizes . A lot of that swag was terrible, and a lot of it he couldn’t accept. But the interesting part was how he allegedly managed to beat Twitter’s system. The most difficult part of this project was preventing the bot from getting banned by Twitter. Scott said that “the most difficult part of this project was preventing the bot from getting banned by Twitter.” The social network has limits in place to stop such activities: unless you have a high follower count, you can only follow up to 2, 000 people yourself, for instance. At the same time, you can’t follow and unfollow users too rapidly or retweet too often. Luckily, Scott’s Python script was able to balance all that and follow every single contest it found. He said his win rate was “pretty miserable” considering the low quality of the prizes. He couldn’t claim the best one, a $4, 000 trip to New York’s fashion week because of taxes and fact that he didn’t live near New York. Nevertheless, he was fond of a few them, especially a cowboy hat autographed by actors in a Mexican soap opera. “It really embodies the totally random outcome of these contests, ” he said. Scott never revealed the name of his Twitter bot, so we’ve reached out to verify his claims — but the prizes appear to check out.

Nano-sized ‘yolks’ should lead to longer-lasting batteries

Those eggs you might have had for breakfast? They’re not just food — they may be the key to longer-running batteries in your devices. Scientists at MIT and Tsinghua University have developed a nanoparticle battery electrode whose egg-like design is built to last. Their invention, which houses a shape-changing aluminum “yolk” in a titanium dioxide cell, can go through charging cycles without degrading like the graphite electrodes in conventional power packs. That could improve not only the overall longevity of the battery, but also its capacity and maximum power. You’d have gadgets that not only hold out for longer between charges, but don’t need to be replaced quite so often under heavy use. This is still a lab experiment, but it’s closer to practical reality than you think. The manufacturing technique is simple, and these materials are relatively easy to find. The yolks already hold up well under stress, for that matter. Even with super-fast charging (which typically shortens a battery’s lifespan), a test unit had just over half its capacity after 500 cycles. So long as the team does get its tech into a shipping product, you could see a wave of hardware that reduces many of your energy-related woes, such as range anxiety in electric cars or phone batteries that die before you’re ready to upgrade.

Phone companies ditching copper wires will have to follow the rules

The age of the copper land-line is nearing its end, but traditional phone lines aren’t going quietly: new rules from the FCC now require service providers notify customers of the impending removal and drawbacks of switching to a VOIP line three months before killing a copper network. It sounds like a reasonable move — customers need to know that the technology replacing their traditional land-line won’t work during a power-outage without an external power source — but not everybody at the FCC is happy with the new rules. “It appears that Chicken Little rules the roost, ” writes Commissioner Ajit Pai in a dissent to the updated transition rules. “By dragging out the copper retirement process , the FCC is adopting ‘regulations that deter rather than promote fiber deployment.'” Pai argues that the FCC is making it more difficult for companies to modernize their networks because lobbyists are claiming that retiring copper will cause the “sky to fall, ” disrupting services and hurting their business model. He has a point — but wouldn’t you want to be notified if the phone company was changing out your voice service worked? Check out the FCC’s official announcement at the source link below.

None of the affected companies have disclosed the specific reason for the outage yet, though they all have already issued vague statements about how they’re working on the issue. Update : Verizon is reporting the issue is resolved as of 8PM ET, however we haven’t seen an update from the others yet. Verizon issued the following statement after fielding numerous complaints on its Twitter account: A connectivity issue is causing a service interruption in our market. Our engineers are aware of this issue and are working with our vendor partners to resolve this issue quickly. At present we do not have an estimated time of resolution. As did T-Mobile: @baegail Customers across all carriers are affected in your region. Engineers are on it and working to restore your services asap! *MMH – T-Mobile USA (@TMobileHelp) August 4, 2015 Sprint followed the same pattern in its statement: We are aware of the impacts to service in which customers may be unable to access voice and some data services. This appears to be an issue caused by a local exchange provider and our network team is working with the provider to restore service to impacted customers as quickly as possible. We apologize for any inconvenience. As did AT&T: Some customers across parts of the Southeast are experiencing wireline and wireless service issues. We are investigating the cause and working as quickly as possible to restore service. We apologize for this inconvenience. According to Re/code , a Sprint rep has hinted that the issue originated at a local exchange provider that works with the affected companies. “We are aware of the impacts to service in which customers across multiple carriers may be unable to access voice and some data services, ” the rep said. “This appears to be an issue caused by a local exchange provider and our network team is working with the provider to restore service to impacted customers as quickly as possible.” Filed under: Internet , Mobile , Verizon , Sprint , AT&T , T-Mobile Comments Via: Gizmodo Source: WATE 6

OnStar hack remotely starts cars, GM working on a fix

Hacker Samy Kamkar unveiled his latest triumph this morning: OwnStar, a tiny box that acts as a Wi-Fi hotspot and intercepts commands sent from a driver’s OnStar RemoteLink app, allowing an unauthorized user to locate, unlock or start the vehicle. Simply place the box somewhere in an OnStar-connected car and wait for the driver to start up the RemoteLink app within range of the vehicle. The driver’s smartphone should automatically connect to OwnStar’s network and, voila , the hacker now has all of the car owner’s information (email, home address, final four digits on a credit card plus expiration date), and control of the car. GM has already issued one patch this morning aimed at securing the RemoteLink app, but it was unsuccessful, according to Kamkar . Kamkar never intended to wreak havok with OwnStar, he said in an interview with Wired . He wanted to expose a vulnerability in the OnStar app and help GM fix it — and it seems as if that’s precisely what’s happening. GM is working to patch the RemoteLink bug now and Kamkar says he’s in contact with the company as they fix it. Kamkar plans to reveal more technical details about OwnStar at Defcon 2015, which runs from August 6th to the 9th in Las Vegas. OwnStar update: GM told WIRED that OnStar bug was fixed, however it’s not actually resolved yet. I spoke with GM & they’re working on it now – Samy Kamkar (@samykamkar) July 30, 2015 This is the second major car-based hack to surface this month. On July 24th, Fiat Chrysler issued a voluntary recall of 1.4 million US vehicles with certain touchscreen entertainment systems, after Wired reported that it was possible to remotely cut the engine, disable and activate the brakes, and track the location of these cars.

US wants the world’s fastest supercomputer by 2025

President Obama has signed an executive order demanding that the US build the world’s fastest supercomputer by 2025. The National Strategic Computing Initiative has been implemented to get the country building an Exascale machine and not fall behind rival nations in the technological arms race. This supercomputer will be developed by arms of the federal government and then be harnessed to speed up research into a wide variety of topics. One example is that the hardware will be used to help NASA better understand turbulence for aircraft design, while another is to crunch the numbers for medical researchers. The US may have more of the Top 500 supercomputers than any other nation, but its prestige in this area is slipping to nations like China and Japan. China’s Tianhe-2 has been the world’s fastest machine for two and a half years in a row, and the list’s authors feel that the US approaching is plunging to a “historical low.” With the weight of the federal government behind it, the NSCI is hoping to steal a march on its rivals and break new ground in the high performance computing sphere. With all of the various challenges that the planet is facing — challenges that we’re told Exascale computing will be able to fix — it can’t come soon enough.

Microsoft now rolling out free Windows 10 upgrades

Today’s the day! Windows 10 is now available in 190 countries as a free upgrade to Windows 7 or 8.1 owners. Replacing an OS is no one’s idea of fun, but we’re actually looking forward to this one. First off, we’ll be leaving behind the most hated version of Windows ever (sorry, Vista). In return, we’ll get one Microsoft was so confident in that they skipped version 9 altogether because hey, Windows 10 sounds better. So how to get it? We’ve got a handy guide , and Microsoft has info here , but if you already reserved your free upgrade, hang in there, as Microsoft says it’s rolling out in waves. Organizations will start to see the new version on August 1st. The computer you have should work just fine, as the minimum requirements haven’t changed much from Windows 7 and 8: A 1GHz processor, 1GB of RAM (2GB for the 64-bit version) and 20GB of free space. The whole thing will take 30-45 minutes, according to Microsoft, not counting the 4-5GB download. Speaking of which, you’ll likely need to be patient, as the roll-out may actually break internet traffic records. As for what’s in it for you, the answer is plenty: you’ll get a much improved interface that takes the best of Windows 7 and 8.1, the new Edge browser, Cortana and better modern apps. You can read more about it in our Windows 10 review , but to cut to the chase, we gave it a stellar 91 rating. Filed under: Software , Microsoft Comments Source: Microsoft
