In the ongoing battle to purge Twitter of content promoting terrorism, the social media company has closed hundreds of thousands of accounts in recent months. In its latest transparency report covering the period from July 1, 2016 through December 31, 2016, Twitter said it shuttered a total of 376,890 accounts “for violations related to promotion of terrorism,” bringing the total number of closures for terror-related content to a colossal 636,248 accounts from August 1, 2015 through December 31, 2016. Faced with such a massive task, Twitter has had to develop proprietary tools designed to automatically identify accounts to take down. The software, which is supported by a team of human investigators, accounted for 74 percent of the most recent batch of reported account closures, the company said. Twitter, like Facebook and other online giants, has been accused in the past of not doing enough to combat extremist activity on its service. Criticism over the last few years prompted the com

In the upcoming Galaxy S8, users will find an extra button on the left side of the phone, just below the volume controls. Pressing it will activate Bixby, Samsung's new voice assistant. Once activated, Bixby will help you navigate what's arguably the most sophisticated piece of technology you own — the smartphone in your hand. If Samsung gets its wish, though, Bixby will eventually do much more than just help you order Lyfts or set up complex calendar appointments. The long-term vision is for Bixby to act as a kind of uber-interface for all of Samsung's products: TVs, wearables, washing machines, even remote controls. Samsung designed Bixby with a specific goal in mind, one that veers away from its fellow voice assistants — Apple's Siri, Amazon's Alexa, Microsoft's Cortana and the Google Assistant. Those platforms were generally built to help users quickly perform common tasks ("Remind me to buy milk") and perform search queries ("What's

Get ready, Android fans, because it looks like Google is going all-in on its emerging phone business. The Google Pixel and Pixel XL smartphones might not have been the best-selling Android handsets of 2016, but there’s precious little question that they were among the best and most desirable new handsets of the year. In fact, they’re still the best new Android phones you can buy right now, and that will continue to be the case until the LG G6, Galaxy S8 and Galaxy S8+ all launch next month. Google’s Pixel and Pixel XL actually would have sold far better than they have so far if not for manufacturing issues that have left Google and its ODM partner HTC completely unable to keep up with demand. Android fans love the idea of getting premium smartphones directly from Google that will always run the latest available version of Android. Of course, Google is planning to follow up its Pixel and Pixel XL with two second-generation models later this year, and the company recently confirmed a

CAPTCHA’s are an irritating but necessary evil. The system that is used to verify whether or not a user is human has been around a while and it had to evolve because machines were getting better at reading the text than humans. With its latest iteration, Google says you’ll no longer have to input anything at all. Invisible CAPTCHA’s are the latest development in the “Completely Automated Public Turing test to tell Computers and Humans Apart.” Google acquired reCaptcha back in 2009. It updated the system in 2013 to allow for the ubiquitous “I’m not a robot” checkbox that’s all over the internet. That version worked by determining the user’s humanity through their clicking style. If the click seemed fishy, a more elaborate test would be offered. But the Invisible CAPTCHA is able to recognize that a user is not a bot simply by analyzing their browsing behavior. In a video, the company explained “Powering these advances is a combination of machine learning and advanced risk analysis t

This is going to sound insane. But since Apple released iOS 10, a lot of people have asked how to hang up at the end of a call. It’s true: The bright red Hang Up button no longer appears on the call screen! For a mysterious reason known only to Apple, once you press your Home button for any reason during a call—to wake the phone because it’s gone to sleep, for example, or to open a different app for reference—the red Hang Up button goes away. Solution: How To End A Call On Your iPhone To hang up, press the Sleep button (the off switch on the side or top of the iPhone). That hangs up on the call. Alternatively, you can tap the person’s name and number at the top to make the red Hang Up button appear—and then tap it. Now you’re no longer baffled—as much.
